Description

Technical Field

[0001] This invention relates to the field of water electrolysis hydrogen production equipment technology, specifically to an intelligent temperature control and heat dissipation device for electrolyzer cables and its control method. Background Technology

[0002] In water electrolysis hydrogen production systems, the electrolyzers require high-current DC cables for power supply during operation. These cables operate at high currents, generate significant heat, and are densely laid. Traditional cable supports are mostly fixed structures, resulting in concentrated stacking and mutual compression of cables. This leads to limited heat dissipation space and easy heat accumulation, causing excessively high cable temperatures, accelerated aging of the insulation layer, and potential safety hazards such as thermal aging, short circuits, and insulation failure.

[0003] In existing technologies, conventional cable supports only have simple support functions, with fixed number of layers, spacing, and width, and cannot be dynamically adjusted according to the number of cables, wire diameter, and heating conditions of the electrolytic cell. Most supports do not have temperature monitoring and active heat dissipation functions, relying solely on natural ventilation for heat dissipation, which is insufficient to meet the heat dissipation requirements of high-current, long-term operation. Existing cable supports are mostly fixed structures, which cannot be adjusted according to changes in the number of cables or the layout of the site. When the electrolytic cell is expanded or new cables are added, the supports need to be remade and installed, resulting in high costs and long cycles. Some supports with heat dissipation functions mostly use overall fan cooling without a layered independent temperature control strategy, resulting in high energy consumption, poor targeting, and low control accuracy.

[0004] Currently, there is a lack of integrated devices that combine dedicated DC cables for electrolytic cells with adjustable stacking spacing, separate wiring, layered temperature measurement, independent air cooling, and refined temperature control methods. Therefore, developing an intelligent heat dissipation system that integrates mechanical adaptive adjustment, distributed temperature sensing, graded air cooling linkage, and process system coordination is a technical problem that urgently needs to be solved in this field.

The front and rear movable covers each have cable holes for the cables to pass through. Within the enclosed space formed by the movable covers, the cables occupy most of the volume. Airflow is forced to pass through the enclosed space at high speed in a small gap, forming a Venturi equivalent throat section with high flow velocity and a high heat transfer coefficient.

[0032] Preferably, the servo telescoping device can be a servo cylinder or a servo electric push rod.

[0033] The Venturi-assisted accelerated cooling device in this invention complements the existing open-type fan cooling method, with both cooling air sources derived from the fan. The specific complementary working mechanism is as follows: (1) Under normal working conditions, the default open directional cooling mode is adopted: In the initial state, the fan is off, all movable covers are open, and the heat dissipation system relies solely on the natural convection of the surrounding ambient air to dissipate heat from the cable; when the cable temperature rises at a certain point and exceeds the set first temperature threshold T1, the fan and the corresponding nozzle are turned on to directionally blow air to cool the temperature rise of the cable until the temperature drops below the safe temperature Ts and then the fan is turned off. (2) In harsh working conditions, the Venturi accelerated cooling mode is adopted: When the cable encounters overload, short circuit impact or extremely high ambient temperature, causing the overall temperature to rise sharply and exceed the set second temperature threshold T2, the heat dissipation system immediately switches to the Venturi accelerated cooling mode. At this time, the fan is turned on and all movable covers are closed. The high pressure airflow from the static pressure box passes through the composite Venturi inlet contraction section smoothly and accelerates, and then passes through the equivalent throat section of the Venturi at high speed, forcibly carrying away the heat of the cable. The heat is discharged from the composite Venturi expansion section, realizing the accelerated cooling of the cable. When the overall temperature of the cable is less than the set second temperature threshold T2, the heat dissipation system automatically switches to open-type directional cooling mode to reduce the energy consumption of the heat dissipation system.

[0034] Preferably, in the Venturi accelerated cooling mode, the airflow entering each layer of cable can be specifically controlled by a flow control valve based on the different temperatures of each layer of cable measured by the layer temperature monitoring module, thereby optimizing heat dissipation and cooling.

[0035] Preferably, when local overheating of the cable is detected, the Venturi accelerated cooling mode can also set a chaotic turbulent local overheating blind zone elimination strategy to eliminate the local overheating blind zone of the cable; the chaotic turbulent local overheating blind zone elimination strategy is as follows: According to the number of layers of the cable tray components, the air volume and air pressure of the Venturi inlet contraction section corresponding to the layer are randomly and alternately varied. At the same time, the height of the streamlined bulge located in the composite Venturi expansion section is randomly adjusted by the pneumatic control system, so that the outlet diameter of each layer of Venturi expansion section produces random dynamic changes. The random pulsation of air volume / air pressure in the inlet section and the random change of the outlet diameter in the expansion section work together to make the airflow entering the equivalent throat section of Venturi generate strong lateral random disturbances while advancing longitudinally, forming chaotic turbulence.

[0036] Specifically, the random and alternating changes in airflow / pressure at the inlet create instantaneous pressure gradients between adjacent layers, inducing interlayer secondary flow. Simultaneously, the random adjustment of the streamlined bulge height within the expansion section dynamically alters the outlet diameter of each Venturi expansion section, causing non-periodic fluctuations in downstream back pressure. These fluctuations, transmitted upstream, further exacerbate the unsteady characteristics of the flow field within the equivalent throat section of the Venturi. Under the coupling effect of inlet and outlet pulsations, the airflow around the cable forms chaotic turbulence with a significant transverse velocity component. This transverse pulsation effectively disrupts the long-term stable laminar boundary layer on the cable surface, causing it to transition into a turbulent boundary layer. This significantly enhances the convective heat transfer coefficient between the cable surface and the airflow, thereby eliminating localized overheating blind spots in the cable.

[0037] In the aforementioned strategy for eliminating the local overheating blind zone in chaotic turbulence, the "random and alternating changes" refer to the following: The central temperature control unit 11 independently adjusts the opening of the flow control valves of each layer according to a pseudo-random sequence or fuzzy rules based on real-time temperature feedback at preset time intervals. At the same time, it issues commands to the pneumatic control system to adjust the height of the streamlined convex hulls in the Venturi expansion sections of each layer, so that the inlet air volume and air pressure of the Venturi inlet contraction section of each layer, as well as the outlet diameter of the composite Venturi expansion section, all exhibit non-periodic dynamic fluctuations. Due to the random differences in air volume / air pressure and outlet diameter between adjacent layers, an instantaneous pressure gradient is formed between layers, inducing the airflow to generate cross-layer secondary flow in the vertical direction. This causes the mainstream of the Venturi equivalent throat section to advance forward while superimposing a transverse pulsating component, forming a chaotic turbulent state with enhanced heat transfer.

[0038] The aforementioned chaotic turbulence local overheating blind zone elimination strategy can be activated in a timely manner when the layered temperature monitoring module detects a local overheating blind zone, or it can be activated periodically. Considering the limited number of temperature sensors in the layered temperature monitoring module, periodically activating the chaotic turbulence local overheating blind zone elimination strategy can eliminate local overheating blind zones in the cable that the layered temperature monitoring module cannot detect.

[0039] A control method for an intelligent temperature control and heat dissipation device for electrolytic cell cables includes the following steps: directional strong cooling of the cable using an open-type directional cooling mode. Step S1: Obtain cable temperature data collected by each temperature sensor, construct a three-dimensional temperature field distribution matrix including layer information, slot information and temperature values, and obtain the cable thermal characteristic model; Step S2: Compare each temperature value with the preset first temperature threshold T1. If any temperature value is ≥ T1, proceed to step S3; otherwise, continue monitoring. Step S3: Identify the floor information corresponding to the temperature value, start the distributed fan unit corresponding to the floor, and force-cool the cables of the floor. Step S4: During the forced air cooling process, continuously monitor the temperature change. When the temperature value continues to rise and reaches the second temperature threshold T2, where T2 > T1, proceed to step S5; when the temperature value falls back to below the safe temperature Ts, proceed to step S6. Step S5: Send a load reduction request signal to the electrolytic cell control system through the communication interface, and at the same time start all distributed fan units to enter the maximum air volume mode; Step S6: Shut down the corresponding distributed wind turbine unit and return to step S1.

[0040] It also includes adaptive learning steps: Step S7: Record historical operating data, including load current, ambient temperature, air-cooled start-up and shutdown records, and temperature change curves for each layer of cable; Step S8: Establish thermal characteristic models for each layer of cable based on historical data to predict the temperature rise rate under different load conditions; Step S9: Dynamically adjust the first temperature threshold T1 and the second temperature threshold T2 based on the prediction results.

[0041] It also includes fault self-diagnosis steps: Step S10: When a distributed fan unit on a certain floor starts up, if the cable temperature on that floor does not drop or continues to rise within a preset time, it is determined that the air-cooled module is faulty and a maintenance alarm is issued. Step S11: When the temperature difference between adjacent cables in the same layer exceeds the preset temperature difference threshold, it is determined to be a local contact failure or insulation aging, and an early warning signal is issued to accurately locate the faulty cable.

[0042] As a further improvement of the present invention, the content of step S4 is replaced as follows: During the forced air cooling process, the temperature change is continuously monitored. When the temperature value continues to rise and reaches the second temperature threshold T2, where T2 > T1, the heat dissipation system switches from the open directional cooling mode to the venturi accelerated cooling mode under harsh conditions. At this time, the fan is turned on, all movable covers are closed, and the high-pressure airflow from the static pressure box passes through the composite venturi inlet contraction section smoothly and accelerates, and then passes through the equivalent throat section of the venturi at high speed, forcibly removing the heat from the cable. The heat is discharged from the composite venturi expansion section, realizing the accelerated cooling of the cable. When the temperature drops below the second temperature threshold T2, the heat dissipation system automatically returns to the open directional cooling mode. If the temperature still cannot drop below the second temperature threshold T2 after turning on the venturi accelerated cooling mode, step S5 is executed.

[0043] In this invention, the first temperature threshold T1 is 85°C, the second temperature threshold T2 is 95°C, and the safe temperature Ts is 70°C.

[0044] Preferably, the thermal characteristic model is established using machine learning algorithms, including multiple linear regression or neural networks.

[0045] Furthermore, the establishment of the machine learning algorithm also includes combining empirical data accumulated during operation of the chaotic turbulence local overheating blind zone elimination strategy with machine learning, based on three-dimensional temperature field monitoring, to achieve self-optimizing thermal management. Specifically, it includes the following steps: Step S12: Record the operating parameters, strategy parameters, and execution results each time the chaotic turbulence local overheating blind zone elimination strategy is executed, and construct a strategy effect dataset; Step S13: Based on the dataset, a predictive model for the effect of chaotic turbulence strategy is established using machine learning algorithms. The input of the model is the operating condition parameters and the strategy parameters, and the output is the expected temperature drop and the degree of improvement in temperature uniformity. Step S14: Before executing the chaotic turbulence strategy, the effect prediction model is used to simulate and evaluate multiple sets of candidate strategy parameters, and the parameter combination with the best expected effect is selected as the strategy parameters for this execution. Step S15: Periodically or after the dataset has accumulated to a preset size, retrain or fine-tune the effect prediction model to achieve adaptive iterative optimization of the strategy parameters.

[0046] Preferably, step S12 further includes recording the temperature distribution changes measured by the layered temperature monitoring module 10 before and after execution, and identifying the newly discovered local overheating blind zone locations during execution, as training samples for the local overheating blind zone prediction model.

[0047] Preferably, the chaotic turbulence strategy self-optimization step further includes: based on the local overheating blind zone prediction model, predicting the probability of the existence of a local overheating blind zone under the current operating conditions; when the predicted probability exceeds a preset threshold, actively triggering the execution of the chaotic turbulence strategy to achieve predictive thermal management.

[0048] The beneficial effects of this invention are: First, the present invention provides an intelligent temperature control and heat dissipation device and control method for electrolytic cell cables, which has multi-dimensional mechanical adaptive adjustment function: the overall height of the bracket component is infinitely adjustable through the height adjustment mechanism (lifting inner column), the number of single-layer cables can be expanded through the telescopic secondary cross brace, and the interlayer spacing is optimized through the interlayer adjustment component. This solves the problem that the fixed bracket cannot adapt to different cable specifications, quantities and site space, and meets the needs of electrolytic cell expansion and renovation.

[0049] Secondly, the intelligent temperature control and heat dissipation device and its control method for electrolytic cell cables of the present invention can realize hierarchical intelligent air cooling control: adopting a two-level temperature threshold control strategy, local air cooling is started when the temperature is slightly over-temperature, and the electrolytic cell control system is linked to reduce the load and start the whole system strong cooling when the temperature is severely over-temperature, forming a closed-loop safety guarantee; distributed fans are started on demand to avoid energy waste caused by overall cooling.

[0050] Third, the intelligent temperature control and heat dissipation device and its control method for electrolytic cell cables of the present invention can coordinate and link the process system: through the communication interface with the electrolytic cell control system, the cable heat dissipation system and the electrolytic cell process system can be coordinated and controlled, and the load can be actively requested to be reduced under extreme working conditions to reduce heat generation from the source, forming a complete safety chain of "monitoring-early warning-cooling-load reduction".

[0051] Fourth, the intelligent temperature control and heat dissipation device and its control method for electrolytic cell cables of the present invention have adaptive and self-diagnostic capabilities: by learning from historical data to establish a thermal characteristic model, a forward-looking predictive control is achieved; by judging the faults of the air-cooling module and the cable body through temperature change trends, intelligent operation and maintenance is achieved.

[0052] Fifth, the intelligent temperature control and heat dissipation device and its control method for electrolytic cell cables of the present invention achieve a significant improvement in heat dissipation performance: by eliminating the contact thermal resistance between cables through a layered layout, optimizing natural convection with adjustable layer spacing, and combining graded forced air cooling, the measured cable operating temperature is reduced by 25℃-35℃ compared with the traditional stacking method, effectively extending the cable service life and ensuring production safety.

[0053] Sixth, the present invention provides an intelligent temperature control and heat dissipation device and control method for electrolytic cell cables. The layered air cooling mechanism is further equipped with a Venturi accelerated auxiliary cooling device for cables under severe heating conditions. The combination of the Venturi accelerated auxiliary cooling device and the original open cooling method can realize a dual-mode complementary mechanism of open directional cooling and Venturi equivalent throat cooling, thus solving the heat dissipation bottleneck under extreme conditions. Specifically, under normal operating conditions, an open-type directional cooling mode is adopted, which only provides localized air cooling to the overheated layer or overheated parts, resulting in low energy consumption and precise control. When encountering extreme conditions such as overload or short circuit, the heat dissipation system automatically switches to Venturi accelerated cooling mode. By using a movable cover to enclose the cable area to form a Venturi tube structure, the airflow velocity flowing over the cable surface is significantly increased by utilizing the Venturi effect, and the forced convection heat transfer coefficient is increased several times. Thus, extreme rapid cooling of the cable is achieved without increasing the power consumption of the fan, solving the problem of insufficient heat dissipation capacity of traditional air cooling under extreme conditions. At the same time, in Venturi accelerated cooling mode, the system can also allocate the air volume of each layer as needed through flow control valves based on the layer temperature monitoring results, avoiding energy waste and achieving a balance between extreme heat dissipation and energy efficiency optimization.

[0054] Seventh, the present invention provides an intelligent temperature control and heat dissipation device and control method for electrolytic cell cables. In the Venturi accelerated assisted cooling device, the cable occupies most of the volume within the enclosed space formed by the movable cover. When the airflow passes through the enclosed space, it is forced to pass through the small gap at high speed, forming a Venturi equivalent throat section with high flow velocity and high heat transfer coefficient, thereby realizing accelerated forced cooling of the cable. The movable cover structure in the Venturi accelerated assisted cooling device can realize the switching between open cooling and closed forced assisted cooling, reflecting a high degree of integration and engineering practicality.

[0055] Eighth, the present invention provides an intelligent temperature control and heat dissipation device and control method for electrolytic cell cables. By setting an online adjustable streamlined hollow shroud, combined with an infrared ranging sensor and a pneumatic control system, the device can dynamically adjust the shape and flow channel cross-section of the Venturi inlet contraction section according to real-time operating conditions, thereby achieving dynamic optimization of forced heat dissipation efficiency and further improving the device's adaptability to complex operating conditions. Through the coordinated control of the random pulsation of airflow / pressure in the inlet section and the random change of the outlet diameter in the expansion section, the flow field in the equivalent throat section of the Venturi forms a chaotic turbulent state with bidirectional disturbance, which significantly enhances the destructive ability of the cable surface boundary layer, effectively eliminates the local overheating blind zone that is difficult to cover by traditional air cooling, and realizes the full-domain refined management of the cable temperature field.

[0056] Ninth, the present invention discloses an intelligent temperature control and heat dissipation device and its control method for electrolytic cell cables. The strategy for eliminating blind zones of chaotic turbulent local overheating in the Venturi accelerated cooling mode utilizes a random and alternating control of airflow and pressure at each layer. This causes the airflow passing through the equivalent throat section of the Venturi to generate transverse random pulsations, effectively disrupting the laminar boundary layer on the cable surface and significantly enhancing the heat exchange effect of local overheating hotspots, thus achieving refined management of the cable temperature field. This strategy for eliminating blind zones of chaotic turbulent local overheating employs a dual-mode triggering mechanism combining on-demand triggering and timed triggering. On-demand triggering mode can quickly respond to local thermal anomalies detected by sensors; timed triggering can eliminate blind zones of local overheating in the cable that cannot be detected by the layered temperature monitoring module. It actively generates chaotic turbulence to comprehensively flush the cable surface, eliminating potential overheating hazards within the temperature monitoring blind zone and playing a proactive role in preventing local overheating blind zones. The organic combination of the two triggering mechanisms forms a complete thermal management closed loop of "passive response + active prevention," significantly improving the system's ability to control cable overheating risks.

[0057] Tenth, the present invention provides an intelligent temperature control and heat dissipation device and control method for electrolytic cell cables. This device deeply integrates a chaotic turbulent local overheating blind zone elimination strategy with machine learning technology, constructing a closed-loop self-evolving thermal management system of "execution-recording-learning-optimization". By recording the operating parameters, strategy parameters, and effect data of each chaotic turbulent strategy execution, a strategy effect prediction model is established, enabling dynamic optimization of strategy parameters. Simultaneously, through the local overheating blind zone prediction model, preventative cooling is proactively triggered before the sensor-monitored blind zone forms, achieving a leap from "passive response" to "predictive elimination". This self-optimization mechanism allows the system to continuously learn and evolve from operational experience. As operating time increases, thermal management efficiency continuously improves, fully embodying the intelligent operation and maintenance concept empowered by artificial intelligence.

[0089] Preferably, the servo telescoping device 50 can be a servo cylinder or a servo electric actuator.

[0090] In this embodiment, the Venturi-assisted accelerated cooling device 29 complements the original open-type fan cooling method, with both cooling air sources taken from the fan 21. The specific complementary working mechanism is as follows: (1) Under normal working conditions, the default open directional cooling mode is adopted: In the initial state, the fan 21 is closed, all movable covers are open, and the heat dissipation system relies solely on the natural convection of the surrounding ambient air to dissipate heat from the cable 28; when the temperature of the cable 28 rises at a certain point and exceeds the set first temperature threshold T1, the fan 21 and the corresponding nozzle are turned on to directionally blow air to cool the temperature rise of the cable 28 until the temperature drops below the safe temperature Ts and then the fan 21 is turned off. (2) In harsh working conditions, the Venturi accelerated cooling mode is adopted: When the cable 28 encounters overload, short circuit impact or extremely high ambient temperature, causing the overall temperature to rise sharply and exceed the set second temperature threshold T2, the heat dissipation system immediately switches to the Venturi accelerated cooling mode. At this time, the fan 21 is turned on and all movable covers are closed. The high pressure airflow from the static pressure box 44 passes through the composite Venturi inlet contraction section 30 smoothly and accelerates, and then passes through the Venturi equivalent throat section 34 at high speed, forcibly removing the heat from the cable 28. The heat is discharged from the composite Venturi expansion section 40, realizing the accelerated cooling of the cable 28. When the overall temperature of cable 28 is less than the set second temperature threshold T2, the heat dissipation system automatically switches to open directional cooling mode to reduce the energy consumption of the heat dissipation system.

[0091] Preferably, in the Venturi accelerated cooling mode, the airflow entering each layer of cable 28 can be specifically controlled by the flow control valve 51 according to the different temperatures of each layer of cable 28 measured by the layer temperature monitoring module 10, thereby optimizing heat dissipation and cooling.

[0092] Preferably, when local overheating of the cable 28 is detected, the Venturi accelerated cooling mode can also set a chaotic turbulent local overheating blind zone elimination strategy to eliminate the local overheating blind zone of the cable 28; the chaotic turbulent local overheating blind zone elimination strategy is as follows: According to the number of layers of the cable tray component 6, the air volume and air pressure of the Venturi inlet contraction section corresponding to the layer are randomly and alternately varied. At the same time, the height of the streamlined bulge 32 located in the composite Venturi expansion section 40 is randomly adjusted by the pneumatic control system, so that the outlet diameter of each layer of Venturi expansion section produces random dynamic changes. The random pulsation of air volume / air pressure in the inlet section and the random change of the outlet diameter of the expansion section work together to make the airflow entering the Venturi equivalent throat section 34 generate strong lateral random disturbances while advancing longitudinally, forming chaotic turbulence.

[0093] Specifically, the random and alternating changes in airflow / pressure at the inlet create instantaneous pressure gradients between adjacent layers, inducing cross-layer secondary flow. Simultaneously, the random adjustment of the height of the streamlined convex 32 within the expansion section dynamically alters the outlet diameter of each Venturi expansion section, causing non-periodic fluctuations in downstream back pressure. These fluctuations, transmitted upstream, further exacerbate the unsteady characteristics of the flow field within the Venturi equivalent throat section 34. Under the coupling effect of inlet and outlet pulsations, the airflow around the cable 28 forms chaotic turbulence with a significant lateral velocity component. This lateral pulsation effectively disrupts the long-term stable laminar boundary layer on the surface of the cable 28, causing it to transition into a turbulent boundary layer. This significantly enhances the convective heat transfer coefficient between the cable 28 surface and the airflow, thereby eliminating localized overheating blind zones on the cable 28.

[0094] In the aforementioned strategy for eliminating the local overheating blind zone in chaotic turbulence, the "random and alternating changes" refer to the following: the central temperature control unit 11 independently adjusts the opening of the flow control valve 51 of each layer according to a pseudo-random sequence or fuzzy rules based on real-time temperature feedback at preset time intervals. At the same time, it issues commands to the pneumatic control system to adjust the height of the streamlined convex 32 in the Venturi expansion section of each layer, so that the inlet air volume and air pressure of the Venturi inlet contraction section 30 of each layer, as well as the outlet diameter of the composite Venturi expansion section 40, all exhibit non-periodic dynamic fluctuations. Due to the random differences in air volume / air pressure and outlet diameter between adjacent layers, an instantaneous pressure gradient is formed between layers, inducing the airflow to generate cross-layer secondary flow in the vertical direction. This causes the mainstream of the Venturi equivalent throat section 34 to advance forward while superimposing a transverse pulsating component, forming a chaotic turbulence with enhanced heat transfer.

[0095] The aforementioned chaotic turbulence local overheating blind zone elimination strategy can be activated in a timely manner when the layered temperature monitoring module 10 detects a local overheating blind zone, or it can be activated periodically. Considering the limited number of temperature sensor points in the layered temperature monitoring module 10, activating the chaotic turbulence local overheating blind zone elimination strategy periodically can eliminate cable local overheating blind zones that the layered temperature monitoring module 10 cannot detect.

[0096] Example 2: A control method for an intelligent temperature control and heat dissipation device for electrolytic cell cables includes the following steps: directional strong cooling of the cable 28 using an open-type directional cooling mode. Step S1: Obtain the temperature data of cable 28 collected by each temperature sensor 20, construct a three-dimensional temperature field distribution matrix including layer information, slot information and temperature values, and obtain the cable thermal characteristic model; Step S2: Compare each temperature value with the preset first temperature threshold T1. If any temperature value is ≥ T1, proceed to step S3; otherwise, continue monitoring. Step S3: Identify the floor information corresponding to the temperature value, start the distributed fan unit 13 corresponding to the floor, and force-cool the cable 28 of the floor. Step S4: During the forced air cooling process, continuously monitor the temperature change. When the temperature value continues to rise and reaches the second temperature threshold T2, where T2 > T1, proceed to step S5; when the temperature value falls back to below the safe temperature Ts, proceed to step S6. Step S5: Send a load reduction request signal to the electrolytic cell control system through the communication interface, and at the same time start all distributed fan units 13 to enter the maximum air volume mode; Step S6: Shut down the corresponding distributed wind turbine unit 13 and return to step S1.

[0097] It also includes adaptive learning steps: Step S7: Record historical operating data, including load current, ambient temperature, air-cooled start-up and shutdown records, and temperature change curves for each layer of cable 28; Step S8: Establish thermal characteristic models of each layer of cable 28 based on historical data to predict the temperature rise rate under different load conditions; Step S9: Dynamically adjust the first temperature threshold T1 and the second temperature threshold T2 based on the prediction results.

[0098] It also includes fault self-diagnosis steps: Step S10: When a distributed fan unit 13 on a certain floor is started, if the temperature of the cable 28 on that floor does not drop or continues to rise within a preset time, it is determined that the air-cooled module is faulty and a maintenance alarm is issued. Step S11: When the temperature difference between adjacent cables 28 in the same layer exceeds the preset temperature difference threshold, it is determined to be a local contact failure or insulation aging, and an early warning signal is issued to accurately locate the faulty cable 28.

[0099] As a further improvement to this embodiment, step S4 is replaced with: continuously monitoring temperature changes during forced air cooling; when the temperature continues to rise and reaches the second temperature threshold T2 (where T2 > T1), the heat dissipation system switches from open directional cooling mode to venturi accelerated cooling mode under harsh conditions. At this time, fan 21 is turned on, all movable covers are closed, and the high-pressure airflow from static pressure box 44 passes smoothly through the composite venturi inlet contraction section 30 and then passes through the equivalent throat section 34 of venturi at high speed, forcibly removing the heat from the cable 28. The heat is discharged from the composite venturi expansion section 40, achieving accelerated cooling of cable 28 until the temperature drops below the second temperature threshold T2, at which point the heat dissipation system automatically returns to open directional cooling mode; if the temperature still cannot drop below the second temperature threshold T2 after activating venturi accelerated cooling mode, step S5 is executed.

[0100] In this embodiment, the first temperature threshold T1 is 85°C, the second temperature threshold T2 is 95°C, and the safe temperature Ts is 70°C.

[0101] Preferably, the thermal characteristic model is established using machine learning algorithms, including multiple linear regression or neural networks.

[0102] Furthermore, the establishment of the machine learning algorithm also includes combining empirical data accumulated during operation of the chaotic turbulence local overheating blind zone elimination strategy with machine learning, based on three-dimensional temperature field monitoring, to achieve self-optimizing thermal management. Specifically, it includes the following steps: Step S12: Record the operating parameters, strategy parameters, and execution results each time the chaotic turbulence local overheating blind zone elimination strategy is executed, and construct a strategy effect dataset; Step S13: Based on the dataset, a predictive model for the effect of chaotic turbulence strategy is established using machine learning algorithms. The input of the model is the operating condition parameters and the strategy parameters, and the output is the expected temperature drop and the degree of improvement in temperature uniformity. Step S14: Before executing the chaotic turbulence strategy, the effect prediction model is used to simulate and evaluate multiple sets of candidate strategy parameters, and the parameter combination with the best expected effect is selected as the strategy parameters for this execution. Step S15: Periodically or after the dataset has accumulated to a preset size, retrain or fine-tune the effect prediction model to achieve adaptive iterative optimization of the strategy parameters.

[0103] Preferably, step S12 further includes recording the temperature distribution changes measured by the layered temperature monitoring module 10 before and after execution, and identifying the newly discovered local overheating blind zone locations during execution, as training samples for the local overheating blind zone prediction model.

[0104] Preferably, the chaotic turbulence strategy self-optimization step further includes: based on the local overheating blind zone prediction model, predicting the probability of the existence of a local overheating blind zone under the current operating conditions; when the predicted probability exceeds a preset threshold, actively triggering the execution of the chaotic turbulence strategy to achieve predictive thermal management.

[0105] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.

The heat is discharged from the composite venturi expansion section, realizing the accelerated cooling of the cable until the temperature drops below the second temperature threshold T2. Then the heat dissipation system automatically returns to the open directional cooling mode. If the temperature still cannot drop below the second temperature threshold T2 after turning on the venturi accelerated cooling mode, step S5 is executed.
