163: Chapter 163 Heat Flow Routing

Jiang Lin did not continue expanding the ARC-NE-01 arc segment.

L-NE-01 was already enough.

Its layered cross-section, curved microchannels, and crystalline residues had already singled it out from ordinary pipeline fragments in the previous round of review.

At this moment, the outer ring candidate arc segment formed by the three points PMCU-17, L-NE-01, and L-NE-02 had also advanced the TM-7 outer ring from a mere directional term into a ring-shaped thermal management service layer with extremely high engineering density.

Continuing to look for new fracture edges could certainly yield more coordinates, more arcs, and more fragments.

But these things would not change the most critical issue for now.

The real issue wasn't where the outer ring was, nor even how large the outer ring was.

But how the outer ring worked.

On the seventy-third day, at 8:40 AM.

The wind season on the Wasteland seemed to have entered a brief lull.

The grayish-white surface outside the Outpost was illuminated by the dim morning light, casting long, distorted rock shadows.

Atmospheric parameters transmitted by the probe showed that the surface dust concentration had dropped by about forty percent.

High-frequency electromagnetic disturbances still existed, making drones unsuitable for low-altitude close approaches, so sample recovery could only be handed over to G-Explorer-C.

G-Explorer-C arrived at L-NE-01 once again.

This time, it had only one mission.

Retrieve the flanged thin flake on the edge of L-NE-01 that had naturally fallen off and detached from the pressure-bearing path.

That flake had already been calibrated yesterday.

It was wedged between two heavily weathered dark brown rocks, with an inclination angle of about fifteen degrees.

Yesterday's low-frequency echo showed that this irregular fragment, about seven centimeters long and two centimeters wide, no longer bore any main structural stress, and the feedback from the tension test did not affect the deep structure beneath it.

Its value lay in providing Jiang Lin with an outer ring material cross-section that could truly be used for functional verification on the analytical bench.

G-Explorer-C advanced close to the ground with a low-posture hexapedal gait, its sacrificial foot tips pressing over the grayish-white particles and emitting a subtle frictional sound.

The macro camera at the front of the robotic arm slowly advanced, and the flake on the screen gradually magnified.

This was not a routine grab.

The material of the flake was extremely special; the edge presented a translucent grayish-black, while the interior was interspersed with blue crystalline textures.

Having weathered through countless Wasteland eras, it might have become abnormally fragile.

If the clamping force of the mechanical claw exceeded the critical value, this excellent sample would instantly shatter into meaningless powder.

But if the clamping force was insufficient, during the jolts on the return journey, it might slip from between the claw gaps and fall into the bottomless structural crevice below.

Jiang Lin spoke in a low voice.

"MPS-Agent α, enable torque feedback assistance, clamping force upper limit 0.15 Newtons. All actions retain manual confirmation."

[Instruction confirmed. Torque feedback assistance has intervened. Feedback loop latency: 12 milliseconds.]

The flexible tentacle at the front of the robotic arm reached out.

Jiang Lin stared at the screen.

The moment the flexible tentacle touched the surface of the flake, the torque sensor transmitted a smoothly rising curve.

He pressed confirm.

The claw tips closed inward on a micrometer scale.

The flake made a slight peeling sound between the two rocks, was steadily clamped at the front of the robotic arm, and then slowly lifted, stored into the sterile sampling box on the back of G-Explorer-C.

The moment he confirmed the chamber lid was closed, Jiang Lin let out a soft breath.

At 10:26, G-Explorer-C returned to the Outpost.

The outer door closed heavily, isolating the sound of the wind and sand outside.

Afterwards, the robotic arm operated automatically, sending the sealed box into the transfer window.

The flake entered the secondary isolation box.

Jiang Lin secured the flake onto the high-precision fixture in the center of the analytical bench.

Accompanied by a subtle mechanical engagement sound, the sample number was automatically written into the Outpost database.

[N73-LNE01-WallFlake-03]

Remarks below.

[Naturally detached edge fragment]

[Already detached from main pressure-bearing path]

[Purpose: Thermal response and microchannel functional verification]

The layout on the analytical bench was distinct.

On the left was an ordinary ablation composite material fragment picked up from the shallow surface of the Wasteland, serving as a conventional material baseline.

On the right was a control sample pressed under high pressure from debris scraped off the inner wall of the PMCU-17 cooling pipeline a few days ago.

In the middle was that L-NE-01 flake that had just experienced long years and saw the light of day again.

Jiang Lin set up the first group of tests.

Test type: Localized point heat pulse.

The input power was suppressed very low, and the upper limit of temperature rise was strictly controlled at 0.6 °C.

Duration twenty seconds, interval ten minutes, repeated for three rounds.

This was of course not to simulate the real thermal load when a behemoth like TM-7 was running.

That scale of thermal load could not be safely reproduced by the Outpost's power supply and isolation conditions.

At this moment, he only wanted to figure out one thing.

When tiny amounts of heat entered this structure filled with microchannels, would it diffuse approximately uniformly like ordinary materials, or would it be redistributed by some deep internal topology?

The first round of control data was quickly generated on the main screen.

As expected, on the ordinary ablation composite material fragment on the left, the hot spot was smooth, dull, and predictable, just like thermal diffusion in standard textbooks.

The control sample of PMCU-17 cooling pipeline debris on the right was slightly more complex.

Due to the specific micro-texture formed during the pressing process of the material, the thermal diffusion exhibited slight directionality along the material's textural direction, and the elliptical isotherms proved its anisotropy.

But essentially, the heat was still diffusing obediently, without any obvious physical inflection points.

When it came to the L-NE-01 flake, the infrared imaging curve on the screen suddenly changed.

The hot spot did not spread out in a normal circular or elliptical shape at all.

For the first fifteen seconds, the highlight thermal front rapidly elongated along the microchannel arc direction, forming a bright line of fire.

At the twenty-third second, an abnormality appeared.

When the thermal front encountered a microchannel bifurcation near a place hard to distinguish with the naked eye, a distinct stagnation appeared.

The temperature curve there suddenly smoothed out, as if temporarily swallowed by some local hysteresis zone.

At the thirty-first second, the heat that should have accumulated and continued to diffuse outward was pulled by another set of tiny channels originally in a low-temperature state, forcibly turning.

That feeling was like a drop of thick ink falling into what looked like an ordinary piece of Xuan paper, not spreading evenly around, but being pulled by the water-conducting fibers hidden inside the paper, meandering and sliding away along an invisible dark vein.

Jiang Lin zoomed in on the screen, his eyes staring intently at the beating data frames.

"MPS-Agent α, perform spatial superposition on the three rounds of data, extract the deflection angle."

The screen flickered once and gave the precise calculation result.

First test, deflection angle 7.2 degrees.

Second test, deflection angle 7.5 degrees.

Third test, deflection angle 7.1 degrees.

The error was extremely small.

This was not a random disturbance caused by environmental noise.

But a stable physical response.

Jiang Lin's fingers tapped quickly on the console, immediately switching directions to start the second group of tests.

Test type: Reverse thermal pulse.

Scientific intuition told him that if this phenomenon was solely due to the material's own structural anisotropy, then applying a thermal pulse in reverse at the same point should give an approximately symmetrical thermal response curve.

But L-NE-01 broke conventional expectations once again.

It did not give a symmetrical result.

After the reverse thermal pulse entered the flake, the thermal front still passed through the microchannel bifurcation node just now.

However, this time the stagnation time was greatly shortened, the heat seemed unwilling to stay too long in this direction, and the attenuation path also became very shallow.

Jiang Lin called both sets of data into the same coordinate system and stacked them together.

The same node.

The same section of physical hysteresis.

Different conduction directions, yet they gave completely different response intensities.

This could no longer be explained by simple thermal conductivity differences.

This was more like a miniature thermal diode network.

The weathered residues inside the microchannels, the micro-geometric structure of the walls, and the possibly existing asymmetric capillary forces together formed a directional thermal response threshold.

The real highlight was in the third group of tests.

Test type: Arc-direction pulse.

This time, the heat source was no longer a single point, but a very short line segment array.

The laser beam uniformly applied a weak thermal wall along the natural arc direction of the L-NE-01 fracture edge.

The infrared heat flow front on the screen showed a more macroscopic and obvious physical bifurcation than before.

Part of the heat flow continued to diffuse with difficulty along the main arc direction relying on the material's background thermal conductivity.

Another part of the heat was quickly introduced into the dense inner microchannel network, forming a brief hysteresis platform lasting several seconds in the infrared field of view.

Jiang Lin noticed that the location of that hysteresis platform was precisely the area on the flake where the grayish-blue crystalline residues were most dense.

The temperature curve there presented an eerie flatness.

Heat was continuously injected, but the temperature did not rise immediately.

After the external heat source was cut off, the temperature did not decay immediately either.

It was like a miniature energy-storage gasket heavily pressed at the bottom of a spring.

First, it silently swallowed part of the heat flow using phase change latent heat, and then spat these heats out along specific microchannels at a beat slower.

The fourth group of tests was composition mapping.

Jiang Lin did not continue heating, but switched to micro-region spectroscopy and near-infrared reflection scanning, projecting the spatial distribution of the grayish-blue crystalline residues onto the infrared hysteresis layer just now.

On the main interface of MPS-Agent α, blue analysis prompt boxes popped up one after another.

[System Diagnostics]

[Significant thermal hysteresis platform detected]

[Hysteresis region and grayish-blue crystalline residue distribution show medium-confidence spatial correlation]

[Hysteresis region and microchannel topological bifurcation nodes show weak correspondence]

[Dynamics judgment: No independent pump-controlled structural features detected in the current flake sample, not supporting interpreting it as a complete active circulation unit]

[Functional judgment: Highly supportive of candidate local passive / semi-passive thermal path redistribution layer outside the main circulation]

Looking at the last line of words on the screen, Jiang Lin's fingers tapping on the keyboard slowly stopped in mid-air and finally left the keys.

Local passive / semi-passive thermal path redistribution layer outside the main circulation.

These few dry professional terms carried the weight of a thousand jun at this moment.

It did not overturn the previous judgment about the TM-7 outer ring high-pressure phase-change cooling network.

On the contrary, it pressed the most difficult-to-explain puzzle piece in that huge network, for the first time, from an abstract field in the system logs back onto a physical structure that could be jointly supported by infrared curves, microchannel topology, and crystalline residues.

The main trunk road of the TM-7 outer ring could of course still rely on high-pressure pump control, main circulation valve groups, phase-change medium reserves, and active pressure regulation.

But the L-NE-01 flake proved that at least at the outer ring end, bypass layer, or local thermal anomaly processing node, the engineers here had designed an adaptive heat flow distribution structure that did not wait for central control commands.

It was not responsible for driving the entire cooling network to operate.

Instead, it was responsible for buying the main circulation a buffer time of a few seconds, tens of seconds, or even minutes when a certain local hot spot suddenly raised its head.

In high-density computing arrays, these few seconds were sometimes the line between life and death.

Jiang Lin turned around and called up the PMCU-17 cache field log on another screen.

Those Wasteland civilization error codes that had once troubled him like garbled code finally connected with the physical structure at this moment.

[CAPILLARY_PRESSURE_DROP]

[THERMAL_PHASE_BYPASS]

[ PHASE-CHANGE_ROUTING_FAILURE ]

These fields were neatly arranged on the right side of the screen.

On the left side of the screen was the brilliant yet eerie thermal pulse infrared response map of the L-NE-01 flake.

The eerie deflection of the thermal front.

The abnormal hysteresis at the branching nodes.

The constant-temperature plateau brought by the grey-blue crystals.

The asymmetry of the arc-directional response.

At this moment, the Physics reality on the left and the historical logs on the right tightly locked together for the first time across the long Wasteland era.

CAPILLARY_PRESSURE_DROP was not merely a simple pipeline pressure drop anomaly.

In this microscopic system, it corresponded to the local driving force changes induced by the temperature gradient within the microchannel capillary structure.

When local heat surged and altered the surface tension σ(T) of the phase-change medium, the capillary pressure difference would change accordingly, forcing the fluid to reroute.

THERMAL_PHASE_BYPASS was not just the mechanical opening of a certain backup Physics pipeline.

It was a local thermal anomaly acting as a trigger that caused a change in the state of the phase-change medium, utilizing volume changes and local pressure differences to squeeze out a new cooling path and redistribution route within the microchannels.

And the final PHASE-CHANGE_ROUTING_FAILURE was not simply a cooling system collapse.

It meant that this phase-change-driven thermal path redistribution network, under the extreme overload at the end of the cataclysm, exhausted its available routing margin and ultimately lost all available escape routes.

Jiang Lin picked up the gel pen on the desk and heavily wrote four characters on the paper notebook.

[Heat Flow Routing]

He put down the pen, picked up the long-since-cold coffee beside him to take a sip, and re-examined the logical chains of the four sets of verifications in his mind.

The first group, point thermal pulses, proved the heterogeneous topology.

The second group, reverse thermal pulses, proved the directional threshold.

The third group, arc-directional thermal pulses, revealed the diversion mechanism.

The fourth group, hysteresis regions superimposed with grey-blue crystal distribution, found the material basis driven by phase change.

Taken out individually, each group was local evidence.

But when they intertwined, they jointly pointed to an extremely advanced macroscopic engineering mechanism.

In this mechanism, heat no longer passively and blindly diffused from high-temperature areas to low-temperature areas.

At least within the L-NE-01 flake that once belonged to the outer ring service layer, the system allowed local thermal anomalies to occur.

When hot spots appeared, it would utilize microchannel topology, phase-change hysteresis absorption peaks, and dramatic changes in capillary pressure difference to actively rewrite the destination of the heat flow.

It was not heat being mechanically carried away.

Rather, heat itself participated in the calculation, determining how it should be carried away.

Having figured this layer out, Jiang Lin solemnly wrote down the first edition of the theoretical definition in his notebook.

[Heat Flow Routing: A passive/semi-passive cooling architecture that utilizes phase-change hysteresis induced by local thermal gradients, changes in capillary pressure difference, and variations in microchannel topological impedance to enable the cooling medium or equivalent heat conduction pathways to prioritize and spontaneously undergo networked redistribution toward hazardous thermal anomaly areas in the absence of global high-efficiency pump control.]

This was solid technical language that could be translated, dimension-reduced, and ultimately brought back to the Real World of 2022.

Mainstream thermal dissipation engineering in the Real World up to today was certainly not rough.

Server cold-plate liquid cooling, immersion cooling, vapor chamber heat pipe technology, microchannel cold plates, large-scale pump-controlled loop systems, and data center rack-level thermal management—behind every technical route accumulated the painstaking efforts of countless engineers and massive amounts of engineering data.

Jiang Lin had no interest in belittling the engineering accumulation of real Earth.

What truly made him stop all actions at this moment was another evolutionary branch displayed to him by the TM-7 outer ring deep within the ruins.

In real engineering thinking, whether dealing with a CPU or a high-load motor, most systems still habitually treated heat as a harmful load that must be eliminated as soon as possible and ruthlessly carried away.

If the heat generation was large, they increased the water pump head and increased the flow rate.

If hot spots were concentrated, they increased the cold plate contact area and piled up red copper.

When local temperature faced the risk of getting out of control, they added thermistors and sensors, wrote thresholds, increased fan speeds after triggering, and if that still failed, reduced frequencies, limited loads, or even powered down and crashed.

Were these methods useful?

Of course they were useful.

They supported the computing power foundation of the modern internet.

But these means were essentially mostly externally imposed strong controls.

The system mastermind directed the radiators to put out fires.

Meanwhile, the mindset of the TM-7 outer ring went a step further and was closer to system self-adaptation.

It allowed the structure itself to participate in judgment.

When the local thermal gradient soared, it did not need the main control chip to issue instructions; heat itself would change the physical state of the local phase-change medium.

Once the phase-change medium changed, the capillary pressure difference changed accordingly, directly leading to adjustments in local fluid impedance.

Once the flow resistance changed, the equivalent thermal paths within the entire microchannel network instantly reorganized.

The cooling capacity of those originally calm areas would be automatically sucked into the out-of-control thermal nodes due to the pressure difference changes.

This was no longer mere heat dissipation.

This was the routing of thermal loads.

Just like internet routers sent data packets to target nodes through IP addresses and congestion algorithms.

This outer ring network of the Wasteland sent precious cooling capacity to the nodes experiencing thermal disasters.

Jiang Lin closed his eyes.

If this logic could be reproduced with a low-end configuration in the Real World, even if only one percent of its essence was reproduced, the first benefited field might not be those wealthy large-scale data centers.

Data centers were too large.

Their systems were too mature, where pulling one hair could affect the whole body.

Such a structure relying on microchannel phase-change routing would tightly suppress the possibility of commercial implementation due to its material requirements, processing precision, long-term maintenance schemes, and comprehensive costs.

The first and most perfect adaptation target, on the contrary, would be those small, high-density computing nodes driven into desperate straits.

And his G-01C.

The thermal management problems faced by low-speed unstructured robotic platforms were completely in a different dimension from constant-temperature and constant-humidity high-density cabinets.

But they had a fatal commonality.

Local heat sources were dense, the external heat dissipation environment was harsh, and once a thermal failure occurred, the dominoes collapsed extremely quickly.

What the Low Entropy Workshop truly had to face next was no longer that closed-tunnel grayscale test of Hengtai.

That checkpoint proved whether G-01C could enter unstructured tunnels and complete basic travel in low illumination, weak communication, and gravelly ground.

What truly determined the depth of cooperation was the next phase of underground long-cycle unmanned inspection verification.

It no longer asked whether the machine could walk across.

It asked whether the machine could still bring itself back safely after being unattended, continuously inspecting for many hours, and repeatedly entering and exiting thermal environment dead ends.

High dust, low ventilation, low illumination, weak communication, and low speed with high torque were the most troublesome combination in underground long-cycle unmanned inspections.

Taken individually, none of them were fatal.

Piled together, they would push the motor, battery, controller, and relay module simultaneously toward the thermal margin boundary.

In past R&D cycles, the core computing power of G-01C's proud safety state machine was mainly used to handle terrain and kinematics problems.

It would calculate the confidence level of the foot-end contacting the ground.

It would monitor the body yaw angular velocity to prevent sideslipping or rollover.

It would analyze the abnormal slope of the spindle current to predict mechanical jamming.

It would assess slip risks and avoid red danger sectors.

These algorithms let the machine know where it could not step.

However, underground long-cycle unmanned inspections would pose even more cruel questions to G-01C.

When the right-front leg knee joint motor was in a continuous high-torque heating state due to continuous climbing.

Meanwhile, the back battery pack had just experienced a high-current climb and was entering the discharge recovery stage with a relatively high internal resistance.

At this exact moment, the controller caused computing power to soar and heat to accumulate due to underlying communication link retransmissions.

What was even more fatal was that the waste heat inside the machine body could not be quickly dissipated in the local low-ventilation environment.

When several of these pressures occurred simultaneously, as the machine's mastermind, what should the system prioritize sacrificing?

Which part of the load should be reduced first?

Should it lower the gait speed at the cost of staying in the risk area for too long?

Should it shorten the inspection radius and declare the mission concluded early?

Should it lie down in place to carry out local rest and wait for natural cooling?

Should it utilize some structural bypass that did not yet exist to guide heat to non-critical casing areas?

Or should it directly judge that the system was on the verge of thermal collapse and trigger the unconditional retreat sequence in advance?

Without the heat flow routing ideology brought by Wasteland technology, Real World engineers would easily split these problems into independent functional modules to solve.

Those working on motors would go thicken the motor cooling fins.

Those working on batteries would go optimize the BMS thermal management strategy.

Those working on communication would go reduce chip power consumption.

Those writing motion control would go optimize gait to save power.

Divide and conquer sounded very scientific.

However, in extreme Physics environments, machines would not die according to the classification frameworks drawn by engineers on PPTs.

They would die along the Physics path where heat accumulated the fastest and structural margin was the weakest.

Jiang Lin took a deep breath, opened his eyes, cleared an area on the desk, and pulled over the mobile workstation.

He no longer looked at the Wasteland screen of the Outpost, but instead created a new reality-side engineering branch library.

He typed out a brand-new file name.

[MPS-HeatRouter_v0.1]

Chinese name.

[Heat Flow Routing Underlying Framework]

Subsequently, he extremely fluently wrote down the architecture description.

Line 1: Core purpose.

[Provide engineering design guidelines for structural redistribution of passive/semi-passive thermal paths targeting local thermal anomalies of complex compact equipment under harsh environments.]

Line 2: First batch of adaptation targets.

[G-01C Underground Long-Cycle Unmanned Inspection Version]

[Low-Ventilation/Near-Zero Effective Ventilation Long-Term Unmanned Equipment]

[Confined Space Liquid Cooling/Air Cooling Hybrid Topology Structures]

Line 3: System inputs.

[Thermal Conduction Path Matrix of Fuselage Base Materials]

[Local Temperature Rise Slope Curves of Key Nodes]

[External Extreme Heat Dissipation Boundary Conditions]

[Preset Passive Bypass Thermal Conduction Structure Models]

[Matrix Positions of Multi-Modal Temperature/Heat Flux Sensors]

[Priority Table of Existing Fault-State Load Reduction Actions]

Line 4: System outputs.

[Priority Physics diversion paths when local hot spots are endangered]

[Position points of potential hidden thermal hysteresis risks inside the system]

[Suggestions for physical thermal conduction bypass positions that must be newly added engineering-wise]

[Thermal dead-end areas that must absolutely not be enclosed in the shell assembly]

[New trigger conditions for fault-state load reduction based on global heat flow routing dynamic calculations]

At the very bottom of this realistic low-end version target vision, Jiang Lin typed a summary.

[Rewrite local hot spots from a dead end that could only rely on global excessive redundancy design to hard-carry into a tactical problem that can be dynamically shunted by a structural bypass network.]

After writing this sentence and pressing the save button, MPS-HeatRouter_v0.1 truly established a foothold in the reality dimension.

Jiang Lin was very clear-headed.

This was by no means a blind reproduction of the TM-7 outer ring.

In the year 2022 of the Real World, there was no such exotic phase-change material like L-NE-01 capable of controlling capillary pressure differences at the molecular level, nor was there the unfathomable microchannel processing precision of the Wasteland.

Nor was there a region-level underground giant computing array on Earth serving as a blood-supplying backend.

If one insisted on hard-copying the hardware, that was simply wishful thinking.

But reality could first learn the first layer.

Learn its art of war.

Learn its top-level architecture mindset.

How should the physical layout of the heat sources be adjusted so that it could naturally form a flow pressure difference.

How should the fuselage's thermal conductive skeleton be arranged so that it can act as a floodway in times of crisis?

When assembling the G-01 C, which positions are dust-proof, but must never have their heat dissipation gaps completely sealed?

Which delicate electronic control parts need to have sufficient thermal retreat paths reserved in their physical structures?

More importantly, the sensor definitions had been rewritten.

Which thermistors should continue to rigidly monitor absolute temperature peaks?

Which probes should monitor the temperature rise slope?

Which sensors should be deployed in those gray dead corners to specifically guard against thermal lag phenomena, rather than just looking at the maximum temperature?

These software and topological-level optimizations did not need to wait for future materials.

They could be used right now.

All that was required was a brand-new design perspective from a bird's-eye dimension.

After setting up the code framework, Jiang Lin did not rest. He directly used the underground long-cycle unmanned inspection environment that the G-01 C was about to face to build a simplified multi-Physics field model, running the first round of thermal flow routing simulations.

The environmental boundary conditions were set to be extremely harsh.

High dust coverage caused the fuselage's radiation heat dissipation coefficient to drop.

Low ventilation.

Up to six hours of continuous low-speed, high-torque off-road operation.

There was a mild, continuous attenuation in communication.

Most troublesome of all, the terrain resistance parameters were set to fluctuate randomly, simulating the gravel, standing water, and mud that might be encountered at any time.

Before importing the new framework, the G-01 C's existing safety state machine would, based on common sense, mark the highest risk points on the entire map in two locations.

A section of extremely steep gravel slope.

A section of slippery, continuous hairpin turn steering.

This completely matched the intuition of traditional robotics engineers.

Climbing slopes took the most effort, steering was the most taxing, and motor power was the highest—naturally making it the most dangerous.

However, after a long period of calculation, when MPS - HeatRouter generated a brand-new global thermal risk topology map, the results completely deviated from traditional intuition.

The red ultra-high risk point was not on that steepest gravel slope at all.

Nor was it in the steering section where the slip was most obvious and the posture was most distorted.

The glaring dark red alarm lingered on the latter half of the map, on an ordinary return section that looked flat and completely unthreatening.

Jiang Lin furrowed his brows, pulled up the temperature rise curve evolving over time, and traced the destination of the heat step by step.

The reason soon had nowhere to hide before the data, being so simple that it sent a chill down one's spine.

During the uphill stage, the servo motors were indeed in a state of high burst, and heat accumulated frantically.

But this was within the design redundancy range and could be endured.

When the machine passed through the most difficult gravel section and entered relatively flat terrain,

the traditional state machine considered the danger resolved and began to lower its guard.

In reality, however, the motion controller was still operating continuously in the background, compensating for tiny gait errors caused by the complex terrain.

In order to penetrate the rock strata and transmit back the complex terrain data from just now, the communication module increased its transmission power.

The back power battery pack had just withdrawn from the high-intensity discharge zone and entered the chemical recovery stage; the waste heat inside the batteries had not yet had time to dissipate and was still radiating outward inside the fuselage.

At this node, the external terrain physical risk indeed dropped in a straight line.

The system instinctively relaxed its global safety alert.

However, the thermal debt owed by the system had not been cleared to zero at all.

Under the physical blockage inside the fuselage, the waste heat formed a severe thermal lag.

If at this moment, on flat road surfaces, the G-01 C merely stepped on a small stone and encountered the slightest foot slip,

to maintain balance, the system's posture correction action would instantly raise the motor load of a certain leg once again.

This originally insignificant additional heat would become the last straw that broke the camel's back.

The locally accumulated hot spot would rush like floodwaters breaking through a dike, rapidly conducting backward from the right front leg's knee joint, along the metal bracket originally used for reinforcement inside the fuselage, to the vicinity of the main controller's fixing plate.

That was a dead corner wrapped by various wiring harnesses, where no sufficient thermal retreat paths had been planned at all.

This would not cause the motor to burn out and smoke immediately.

The true terror lay in that it would bring the temperature of the controller's core components close to the frequency-reduction red line, thereby infinitely compressing the subsequent thirty-minute precious retreat window, or even directly crashing and dying deep inside the tunnel.

Jiang Lin looked at the thermal risk map that revealed the implicit crisis, and gently nodded in the silent laboratory.

This was the true achievement.

If this thing were brought back to the Real World and handed over to the Low Entropy Workshop engineering team, then Hengtai's next stage of underground long-cycle unmanned inspection verification would no longer be just letting the G-01 C run a few more laps in the tunnel.

It would turn into a systematic verification of the complete machine's thermal debt, mission radius, retreat window, and fault-state self-preservation capability.

The Low Entropy Workshop could hold the blueprints and tell Party A before departure:

"The section of road from C4 to C5 on the map may not look like the most dangerous terrain, but it is precisely the section with the highest system thermal risk and the most prone to crashing."

"The machine stops at point B2 to rest and regroup, not because the motor performance is conservative, but to completely pay off the thermal debt incurred in the first half at this node with better ventilation conditions."

"When cutting and processing structural part D in the middle of the fuselage, we cannot just look at bending strength; it must be replaced with an aluminum alloy with higher thermal conductivity, because it must concurrently serve as a thermal conduction bypass when the system is overloaded."

"Starting today, sensor No. 3 deployed next to the main control board must not only check whether the peak temperature is overloaded, but also calculate the temperature rise slope and thermal lag time window in real time."

This was arming Real World machines with Wasteland top-level thinking.

A judgment framework born from the ruins of a future advanced civilization, yet capable of being used by 2022 Real World machines.

Jiang Lin typed on the keyboard, writing the first round of virtual simulation results into the application instructions.

[Application 1: Before entering Hengtai's underground long-cycle unmanned inspection verification, the G-01 C must undergo a full-road condition MPS thermal flow routing risk preview.]

[Application 2: The system must possess the ability to identify hidden traps with low terrain risk but high thermal debt risk, conducting thermal early warnings especially for the return section.]

[Application 3: Engineering structure reorganization. Physically connected structural thermal conduction bypasses must be compulsorily designed for the four joint motors, the main controller fixing board, the core battery compartment, and the communication relay module.]

[Application 4: Algorithm upgrade. The temperature rise slope monitored by sensors, the thermal lag time of various nodes in the system, and the real-time status of local thermal conduction paths must all be written into the next-generation G-01 C safety state machine.]

[Application 5: Output a list of forbidden operating conditions under extreme circumstances, providing impassable physical boundary conditions for the customer's on-site verification plan.]

Midnight.

On the Outpost's main screen, two contrasting system diagrams quietly stood displayed.

On the left was the dim and deep Wasteland side.

The chart was named: [TM-7 Outer Ring Thermal Management Failure Model v0.1]

It was covered with complex crystal distribution maps, phase transition critical formulas, and incomplete pipeline topologies.

On the right was the Engineering-filled Real World side.

The chart was named: [MPS - HeatRouter _ v0.1]

Above it was a wireframe perspective view of the G-01 C quadruped robot, along with bypass routing suggestions marked with temperature gradients.

Between these two blueprints representing different stages of civilization development, there were only four concise connection lines.

[Local Thermal Gradient]

[Phase Transition Hysteresis]

[Capillary Pressure Difference]

[Microchannel Topology]

It was precisely these four seemingly simple physical connections that compressed and translated a dead outer ring relic deeply buried beneath the Wasteland weathering layer into a set of technical language completely readable and usable by the Real World engineering system.

Jiang Lin stood up, walked to the whiteboard at the edge of the laboratory, picked up a marker, and wrote down the final achievement summary of this long day.

[Achievement 1: Cross-scale thermal response verification of the naturally peeled-off L-NE-01 flake completed.]

[Achievement 2: Confirmed the existence of stable thermal front directional deflection and node hysteresis phenomena in the microchannel structure.]

[Achievement 3: Proved the significant correspondence between the grayish-blue crystal residual area and the infrared thermal hysteresis platform, officially listing it as a candidate for Wasteland phase change medium residues.]

[Achievement 4: Completed conceptual reconstruction of the Wasteland underlying log THERMAL_PHASE_BYPASS, reinterpreting it as the fault-state passive bypass action of the thermal flow routing network.]

[Achievement 5: Established the Real World engineering mapping framework MPS - HeatRouter _ v0.1, prioritizing adaptation for the G-01 C underground long-cycle unmanned inspection version.]

In the assembly room, it was so quiet that only the slight humming sound of the instrument cooling fans remained.

Having completed its mission, the G-Explorer-C, like a tired beast, quietly lay prone on the automatic lifting platform to charge.

At the tip of its mechanical probe pole, there was still a bit of black micron-level powder that could not be cleaned off no matter what with high-pressure airflow.

That was the ash left after the death of this planet.

Meanwhile, inside the sterile isolation rack, the E-02 recording box lay quietly, next to the PMCU-17 peripheral maintenance computing unit, which, like a black obelisk, stubbornly refused to answer any redundant questions.

Deep in the wilderness seventy-three kilometers away from here, the area code-named Northeast Seventy-Three was still shrouded in wind and sand.

The main structure of L-NE-01 remained deeply buried among layers of grayish-white gravel and the long-cemented thin-shelled strata, waiting for the next excavation whose arrival time was unknown.

Everything seemed unchanged.

Yet Jiang Lin knew in his heart that during this long night of analysis, what he had obtained from those dead Wasteland ruins was a brand-new thermal management concept that could enable Real World machines to break through their own dimensions.

Here, heat was no longer a mindless enemy that only blindly burned components and killed the system.

In this sufficiently precise and grand conceptual structure, as long as it was given correct guidance and sufficient paths, even the most violent heat could become a milestone guiding the system to survive.

And these profound milestones could be interpreted by human engineers.

Could be compressed by mathematical models.

Could be rewritten by code.

Could grow anew within humanity's metal shells in the Real World, through a compromise of being one tier lower in grade, one tier rougher in craftsmanship, and one tier behind in basic materials.

Jiang Lin returned to the desk, opened the thick paper log, uncapped his pen, and wrote the final two lines at the bottom of this page.

[Day 73: The thermal flow routing concept completed its first Real World-side abstraction.]

After writing, he closed the notebook and pressed Ctrl + S on the keyboard.

The green progress bar at the bottom right corner of the screen flashed past, and the system prompt sound rang crisply, representing that all data was saved and archived.

The core file name on the main screen finally stabilized firmly, no longer flashing.
