Description

Technical Field

[0001] This invention belongs to the field of server heat dissipation technology, and in particular relates to a sweating-type heat dissipation method and system for servers or intelligent robots. Background Technology

[0002] With the rapid development and expanding application of artificial intelligence (AI) technology, the performance requirements for servers are indeed becoming increasingly stringent. As server performance improves, power consumption also increases, leading to greater heat generation. High-performance processors generate significant amounts of heat during large-scale parallel computing. If this heat cannot be effectively removed, it can cause hardware overheating, impacting performance and potentially damaging the equipment. Therefore, high-performance servers require more advanced and efficient cooling systems. Currently, liquid cooling and air cooling are the two most common cooling methods in data centers and high-performance computing equipment. However, in the long term, servers or intelligent robots should possess a self-heating mechanism similar to that of animals or plants.

[0003] Disadvantages of existing technology: Environmental Dependence: The heat dissipation efficiency of both liquid-cooled and air-cooled systems is affected by the ambient temperature. At high ambient temperatures, the heat dissipation capacity of both systems decreases. This means that maintaining equipment within its ideal operating temperature range is more difficult in hot environments.

[0004] High cost: Liquid cooling systems typically have higher construction costs. While the cooling system itself is relatively simple, efficient air-cooled solutions may require complex airflow designs and regular cleaning to prevent dust accumulation. Liquid cooling systems are more complex to design and install, requiring regular checks of the coolant condition, leak prevention, and maintenance of the system's seals.

[0005] Long-term reliability: Both systems may face reliability issues during long-term operation. Fans in air-cooled systems may become less efficient or stop working altogether due to dust accumulation, wear, or malfunction. Liquid-cooled systems may experience reduced heat dissipation efficiency due to coolant leaks, corrosion, or pipe blockages.

[0006] This invention aims to provide a sweat-wicking heat dissipation method and system for servers or intelligent robots, hoping to achieve the following: Independent of the environment and does not affect ambient temperature: This invention dissipates heat through the rapid evaporation of the discharged liquid, with the hot air from the evaporation being released to other locations. The ambient temperature will not affect the system's cooling and heat dissipation, and the system's heat dissipation will not affect the surrounding environment.

[0007] Reduced costs: Compared to the high cost of immersion systems, the returned liquid can be allowed to cool naturally and be recycled.

[0008] Environment-independent heat dissipation: design a heat dissipation method that does not depend on environmental temperature and does not change environmental temperature, ensuring stable operation of the equipment under various climate conditions.

[0009] Cost-effectiveness and sustainability: reduce the construction and operation cost of the heat dissipation system through innovative design, improve resource utilization, and achieve economic, environmentally friendly and stable heat dissipation effect.

[0010] Long-term reliability improvement: simplify the heat dissipation structure, reduce maintenance requirements, and use protective packaging technology to improve the long-term operation reliability of the heat dissipation system. SUMMARY

[0011] The purpose of the present application is to provide a sweat-type heat dissipation method and system for servers or intelligent robots to solve the technical problems existing in the prior art.

[0012] To solve the above technical problems, the technical solution adopted by the present application is as follows: In a first aspect, a sweat-type heat dissipation method for servers or intelligent robots is provided, which adopts a heat dissipation system including a moisture-wicking module, an intelligent control module, a liquid circulation module and a protective packaging module, comprising the following steps: S1: The heat generating elements of the server or intelligent robot generate heat, which is transferred to the moisture-wicking module attached to the surface of the heat generating elements. The moisture inside the moisture-wicking module absorbs heat and changes from liquid to gas, performing preliminary heat absorption; S2: The gasified moisture escapes through the micropores on the surface of the moisture-wicking material, passes through the protective packaging structure wrapped on the outside of the moisture-wicking material, and enters the airflow guide channel inside the server or intelligent robot through the air permeable channel. Finally, it is guided out of the device to complete the transfer and discharge of heat; S3: The intelligent control module collects real-time temperature data of the heat generating elements and the moisture-wicking material, and compares the real-time temperature data with the preset temperature threshold. If the temperature reaches the upper temperature threshold, the microcontroller sends a control signal to the drive circuit to accelerate the evaporation rate of the moisture-wicking material through electric field or magnetic field stimulation; S4: When the temperature drops to the lower temperature threshold, the microcontroller controls the drive circuit to weaken the stimulation intensity or use reverse stimulation to slow down the evaporation rate of the moisture-wicking material or promote its reabsorption of liquid; S5: The gasified moisture discharged outside the device condenses into liquid droplets in the preset liquid collection tank, and the liquid droplets fall into the liquid collection tank. The liquid in the liquid collection tank is transported to the cooling device through the delivery pipeline. The cooling device is a heat exchanger or a natural cooling coil. After the liquid is cooled by the cooling device, it is re-injected into the moisture-wicking material through the delivery pipeline, forming a liquid closed loop or semi-closed loop circulation.

[0013] Preferably, the moisture absorption and sweat releasing module in step S1 uses a moisture absorption and sweat releasing material, which is a composite material with high moisture absorption and rapid evaporation characteristics, and is composed of 40-60% by mass of a high molecular moisture absorption resin and 40-60% by mass of porous ceramic particles, the porous ceramic particles have a pore size of 50-200 microns, and the surface thereof is treated to be hydrophilic to improve the moisture absorption and evaporation efficiency of the material.

[0015] Preferably, the specific process of step S3 is as follows: S31: The temperature sensor in the intelligent control module collects real-time temperature data of the heat generating element and the moisture absorption and sweat releasing material, the microcontroller pre-stores the safety temperature interval of the heat generating element of the server or intelligent robot, which contains an upper temperature threshold, and real-time receives two-way real-time temperature data from the temperature control sensor: one is the surface temperature of the heat generating element, and the other is the real-time temperature of the moisture absorption and sweat releasing material; S32: The microcontroller receives the comparison between the real-time temperature data and the preset temperature threshold, and when the microcontroller determines that any one of the temperature data reaches or exceeds the preset upper temperature threshold, the control logic for accelerating heat dissipation is triggered, the corresponding electrical signal instruction is generated and transmitted to the driving circuit, the electrical signal control instruction is a high-low level signal or a pulse signal, including three key parameters of stimulation type, stimulation intensity and stimulation duration; S33: The driving circuit analyzes the stimulation type, intensity and duration contained in the signal through the built-in signal analysis module, and then converts them into physical quantity signals that can directly drive the execution element; S34: The process of rapid migration of water in the material to the surface, rapid conversion of surface water into gaseous state, and accelerated escape of gaseous water through the micropores of the material is accelerated, rapidly taking away the heat generated by the heat generating element of the server / intelligent robot, so that the temperature of the device falls back to the safety interval.

[0016] Preferably, the specific process of step S4 is as follows: After the moisture absorption and sweat releasing material accelerates evaporation and heat dissipation, the temperature control sensor will collect the temperature change of the heat generating element and the material in real time, and feed back the data to the microcontroller, if the temperature drops to the preset lower threshold, the microcontroller will send a signal to weaken or stop the stimulation, and the driving circuit will reduce the intensity of the electric field / magnetic field or stop output, and the material will return to the normal moisture absorption and release state.

[0017] Preferably, the cooling device of step S5 cools the liquid to 15-25 DEG C, ensuring that the temperature of the liquid injected into the moisture-wicking material is 5-10 DEG C lower than the current temperature of the moisture-wicking material, thereby improving the absorption efficiency of the moisture-wicking material for the liquid.

[0018] In a second aspect, a moisture-wicking heat dissipation system for a server or intelligent robot is provided for implementing the moisture-wicking heat dissipation method for a server or intelligent robot. The moisture-wicking module comprises a composite material with high moisture absorption and rapid evaporation characteristics, which is attached to the surface of the heat-generating element of the server or intelligent robot, and is used to absorb the heat generated by the heat-generating element and cause phase change of the moisture inside the material, thereby removing the heat from the heat-generating element through evaporation of the moisture. The intelligent control module comprises a temperature control sensor, a microcontroller, and a driving circuit. The microcontroller is electrically connected to the temperature control sensor and the driving circuit, can receive the temperature data transmitted by the temperature control sensor, and generate a control signal according to a preset temperature threshold. The driving circuit is connected to the moisture-wicking material, and can adjust the moisture absorption and release rate of the moisture-wicking material through electric field or magnetic field stimulation according to the control signal of the microcontroller. The liquid circulation module comprises a liquid collection tank, a cooling device, and a delivery pipeline. The cooling device is a heat exchanger or a natural cooling coil, which is in communication with the liquid collection tank through the delivery pipeline, and is used to cool the liquid collected in the liquid collection tank. The delivery pipeline also connects the cooling device and the moisture-wicking material, and re-injects the cooled liquid into the moisture-wicking material, forming a closed-loop or semi-closed-loop liquid circulation. The protective packaging module comprises a waterproof and breathable film or a microporous ceramic, which is wrapped on the outside of the moisture-wicking material, and has a breathable passage at a position corresponding to the evaporation area of the moisture-wicking material.

[0019] The beneficial effects of the present application include: 1. Strong environmental adaptability: Compared with traditional liquid cooling and air cooling systems, the "sweating" heat dissipation method proposed by the invention is not affected by environmental temperature. Regardless of how the external environmental temperature changes, through the moisture absorption and sweating process of the biomimetic evaporative cooling material and the intelligent temperature control adjustment mechanism, the device can always operate stably within the set temperature range, significantly enhancing the adaptability of servers or intelligent robots in various climate conditions.

[0020] 2. Significant energy saving and consumption reduction: The technical solution utilizes the principle of natural evaporation cooling, without the need for additional refrigeration equipment (such as air conditioners, water chillers) to provide a cooling source, greatly reducing energy consumption. At the same time, the closed-loop or semi-closed-loop design of the liquid circulation system allows the evaporative liquid to be recycled, cooled, and reused, further improving resource utilization and reducing operating costs.

[0021] 3. Quiet operation and low maintenance requirements: Since the invention eliminates mechanical devices such as fans and pumps, it achieves noiseless operation, which is conducive to creating a quiet working environment. In addition, the heat dissipation system composed of biomimetic evaporative cooling materials and intelligent control modules has a simple structure, eliminating the need for frequent cleaning, maintenance, or replacement of parts, greatly reducing maintenance workload and related costs.

[0022] 4. Improved heat dissipation efficiency and precise temperature control: Biomimetic evaporative cooling materials have high moisture absorption and rapid evaporation characteristics, allowing them to quickly absorb and dissipate device heat, with a higher heat dissipation efficiency than traditional liquid cooling and air cooling systems. The intelligent temperature control adjustment mechanism can dynamically adjust the moisture absorption and sweating rate according to the actual heat load of the device, achieving precise control of the device temperature and ensuring stable operation under high-performance computing tasks.

[0023] 5. Environmentally friendly and sustainable: The invention uses natural evaporation cooling, with no harmful substance emissions and no negative impact on the environment. The high-efficiency recycling and reuse mechanism of the liquid circulation system reduces water consumption, meeting the requirements of green data centers and sustainable development. Compared to liquid cooling technology that relies on artificial refrigerants and complex piping systems, this solution has obvious advantages in environmental protection and sustainability.

[0024] 6. Enhanced long-term operation reliability: By simplifying the structure of the heat dissipation system, eliminating mechanical moving parts (such as fans and pumps), and using waterproof and breathable membranes or microporous ceramics for protective packaging, the invention reduces system failure rates and maintenance requirements, improving the long-term operation reliability of the heat dissipation system. In contrast, traditional liquid cooling and air cooling systems are relatively weak in long-term reliability due to environmental factors, mechanical wear, liquid leakage, and other issues.

[0025] In summary, the "sweating type" heat dissipation technology of the present application has significant advantages over existing liquid cooling technology in terms of environmental adaptability, energy saving and consumption reduction, silent operation, heat dissipation efficiency, temperature precision control, environmental friendliness, sustainability and long-term reliability, etc., and provides a more advanced, economical, environmentally friendly and stable heat dissipation solution for high-performance servers and intelligent robots.

[0030] The following will be described in conjunction with the accompanying Figures 1-4 Further detailed description of the present application: Example 1 Referring to the accompanying Figure 1 , Figure 3 , Figure 4 A sweating type heat dissipation method for servers or intelligent robots, which adopts a heat dissipation system including a moisture absorption and sweating module, an intelligent control module, a liquid circulation module and a protective packaging module, comprises the following steps: S1: The heat generated by the operation of the heat generating elements of the server or intelligent robot is transferred to the moisture absorption and sweating module attached to the surface of the heat generating elements, and the moisture inside the module absorbs heat and changes from liquid to gas, thereby preliminarily absorbing heat.

[0031] S2: The gaseous moisture escapes through the micropores on the surface of the moisture absorption and sweating material, passes through the protective packaging structure wrapped on the outside of the moisture absorption and sweating material, and enters the airflow guiding channel inside the server or intelligent robot through the air permeable channel, and is finally guided out of the device to the outside, thereby completing the transfer and discharge of heat.

[0032] S3: The intelligent control module collects real-time temperature data of the heat generating elements and the moisture absorption and sweating material, and transmits the data to the microcontroller; after receiving the real-time temperature data, the microcontroller compares it with the preset temperature threshold value, and if the temperature reaches the upper limit temperature threshold value, the microcontroller sends a control signal to the driving circuit, and the driving circuit accelerates the evaporation rate of the moisture in the moisture absorption and sweating material by stimulating it through an electric field or a magnetic field.

[0033] S4: When the temperature drops to the lower temperature threshold, the microcontroller controls the driving circuit to weaken the stimulation intensity or adopt reverse stimulation, slows down the moisture evaporation rate of the moisture-wicking material or promotes its liquid reabsorption, and maintains the device temperature stable.

[0034] S5: The gaseous moisture outside the device condenses into liquid droplets in the preset liquid collection tank when it meets the cold, and the liquid droplets fall into the liquid collection tank; the liquid in the liquid collection tank is transported to the cooling device through the conveying pipeline, the cooling device is a heat exchanger or a natural cooling coil, and the liquid is cooled and treated through the cooling device, and then re-injected into the moisture-wicking material through the conveying pipeline, forming a liquid closed loop or semi-closed loop circulation.

[0035] In this embodiment, the moisture-wicking module in step S1 uses moisture-wicking material, which is a composite material with high moisture absorption and rapid evaporation characteristics, and is composed of 40%-60% of high molecular moisture absorption resin and 40%-60% of porous ceramic particles. The pore size of the porous ceramic particles is 50-200 μm, and the surface is treated with hydrophilic treatment to improve the moisture absorption and evaporation efficiency of the material.

[0036] Embodiment 2 On the basis of embodiment 1, the protective packaging structure in step S2 uses a waterproof and breathable film or microporous ceramic with a reserved breathable channel, the waterproof and breathable film has a breathable amount of 500-1000 g / (m²·24h) and a waterproof level not less than IPX5; the microporous ceramic has a porosity of 30%-50% and a permeability coefficient greater than or equal to 1×10-12 m², preventing liquid water from penetrating into the sensitive electronic element area inside the device.

[0037] The specific process of step S3 is as follows: S31: The temperature sensor in the intelligent control module collects real-time temperature data of the heating element and the moisture-wicking material, the microcontroller pre-stores the safe temperature interval of the heating element of the server or intelligent robot, which includes the upper temperature threshold, and receives two real-time temperature data from the temperature control sensor in real time: one is the surface temperature of the heating element, and the other is the real-time temperature of the moisture-wicking material; S32: The microcontroller receives the comparison between the real-time temperature data and the preset temperature threshold, and when the microcontroller determines that any one of the temperature data reaches or exceeds the preset upper temperature threshold, the control logic of accelerating heat dissipation is triggered, and the corresponding electrical signal instruction is generated and transmitted to the driving circuit. The electrical signal control instruction is a high-low level signal or a pulse signal, including three key parameters of stimulation type, stimulation intensity and stimulation time length, to adapt to different heat load scenarios: When selecting electric field stimulation, the signal needs to define the target voltage value, which is usually set to 5-20 V; When selecting magnetic field stimulation, the signal needs to define the target magnetic induction intensity, usually set to 0.1-0.5T; At the same time, the output duration or pulse frequency of the signal is defined, such as pulse power supply, the frequency is 1-10Hz, to avoid continuous stimulation leading to material performance degradation, and to ensure that the stimulation intensity matches the thermal load; S33: The driving circuit analyzes the stimulation type, intensity, and duration contained in the signal through the built-in signal analysis module, and then converts it into a physical quantity signal that can directly drive the execution element: If it is an electric field stimulation instruction, the driving circuit amplifies the low-voltage control signal (such as 3.3V / 5V) output by the microcontroller to the target voltage (5-20V), and adjusts the output current stability to ensure that the electric field intensity meets the requirements; If it is a magnetic field stimulation instruction, the driving circuit generates a magnetic field with a corresponding magnetic induction intensity (0.1-0.5T) by controlling the current size of the internal coil (such as adjusting the PWM duty cycle); The output end of the driving circuit is connected to the moisture-wicking material through conductive electrodes (for electric field stimulation) or electromagnetic coils (for magnetic field stimulation): Electric field stimulation: Two conductive electrodes are attached to the two sides of the moisture-wicking material to form a stable electric field action area; Magnetic field stimulation: The electromagnetic coil is wrapped around or close to the moisture-wicking material, so that the material is in the magnetic field generated by the coil; The driving circuit outputs a stable electric field or magnetic field to the conductive electrode or electromagnetic coil according to the analyzed parameters, directly acting on the moisture-wicking material, and completes the conversion of the control instruction to physical stimulation; S34: The electric field acts on the high-molecular moisture-absorbing resin (polar molecules) in the material, causing the resin molecules to be polarized, the hydrogen bond force between the molecules to be weakened, and the combined water (not easy to evaporate) originally absorbed by the resin to be converted into free water (easy to evaporate); Ion migration: The trace ions in the material move directionally under the action of the electric field, producing a weak thermal effect (auxiliary heating), while breaking the adsorption force between water and the material surface, promoting the migration of water to the material surface; Micropore expansion: The electric field may cause the micropore structure of the porous ceramic particles to expand slightly, increasing the cross-sectional area of the water evaporation channel and accelerating the escape of gaseous water from the material interior to the surface; Molecular motion intensification: The magnetic field acts on the water molecules (polar molecules) in the material, causing the thermal motion rate of the water molecules to accelerate, the molecular kinetic energy to increase, and the water molecules to be more easily released from the liquid state to the gaseous state; Interfacial tension reduction: The magnetic field can reduce the interfacial tension between water and the material (high-molecular resin, ceramic particles), reduce the residence time of water in the material, and accelerate the migration of water to the evaporation surface; No thermal effect interference: Compared with electric field, the additional heat generated by magnetic field stimulation is very small, avoiding the temperature rise of the material caused by the stimulation itself, and only focusing on accelerating the evaporation of water; Whether it is electric field or magnetic field stimulation, the final result is to realize the rapid migration of water in the material to the surface → the rapid conversion of surface water into gaseous state → the acceleration of the process of gaseous water escaping through the material micropores, thereby improving the overall heat dissipation efficiency, quickly taking away the heat generated by the heating elements of the server / intelligent robot, and making the equipment temperature fall back to the safe interval.

[0038] Embodiment 3 On the basis of embodiment 1 or embodiment 2, the specific process of step S4 is as follows: When the moisture-wicking material accelerates evaporation and heat dissipation, the temperature control sensor will collect the temperature changes of the heating element and the material in real time, and feed back the data to the microcontroller. If the temperature falls below the preset lower threshold, the microcontroller will send a signal to weaken the stimulation or stop the stimulation, and the drive circuit will accordingly reduce the electric field / magnetic field strength or stop output, and the material will return to the normal moisture absorption and release state, forming a closed loop of monitoring - control - feedback - adjustment, ensuring that the heat dissipation rate and the heat load are dynamically matched, and maintaining the stable temperature of the equipment.

[0039] The cooling device of step S5 cools the liquid to 15-25℃, ensuring that the temperature of the liquid injected into the moisture-wicking material is 5-10℃ lower than the current temperature of the moisture-wicking material, thereby improving the absorption efficiency of the moisture-wicking material to the liquid.

[0040] A moisture-wicking heat dissipation system for servers or intelligent robots is used to realize the moisture-wicking heat dissipation method for servers or intelligent robots, as shown in Figure 2 As shown, it comprises a moisture-wicking module, an intelligent control module, a liquid circulation module and a protective packaging module. The moisture-wicking module comprises a composite material with high moisture absorption and rapid evaporation characteristics, which is attached to the surface of the heating element of the server or intelligent robot, and is used to absorb the heat generated by the heating element and cause phase change of the water in the material, and then take away the heat from the heating element through water evaporation; The intelligent control module comprises a temperature control sensor, a microcontroller and a drive circuit. The temperature control sensor is connected to the heating element of the server or intelligent robot and the moisture-wicking material, and is used to collect the temperature data of the heating element and the moisture-wicking material in real time; The microcontroller is electrically connected with the temperature control sensor and the drive circuit respectively, can receive the temperature data transmitted by the temperature control sensor, and generate a control signal according to the preset temperature threshold; The drive circuit is connected with the moisture-wicking material, and can adjust the moisture absorption and release rate of the moisture-wicking material through electric field or magnetic field stimulation according to the control signal of the microcontroller; The liquid circulation module comprises a liquid collecting tank, a cooling device and a conveying pipeline, the liquid collecting tank is arranged below or around the moisture-wicking and sweat-releasing material and is used for collecting liquid droplets condensed after evaporation of the moisture-wicking and sweat-releasing material; The cooling device is a heat exchanger or a natural cooling coil, which is communicated with the liquid collecting tank through the conveying pipeline and is used for cooling the liquid collected by the liquid collecting tank; The conveying pipeline also connects the cooling device and the moisture-wicking and sweat-releasing material, so that the cooled liquid is re-injected into the moisture-wicking and sweat-releasing material, forming a closed loop or a semi-closed loop of liquid circulation; The protective packaging module comprises a waterproof and breathable film or a microporous ceramic, which is wrapped on the outside of the moisture-wicking and sweat-releasing material and has a breathable passage at a position corresponding to the evaporation area of the moisture-wicking and sweat-releasing material; meanwhile, an air flow guiding passage is arranged in a region corresponding to the protective packaging structure inside the server or the intelligent robot, which is used for guiding the gas generated by evaporation of the moisture-wicking and sweat-releasing material out of the equipment.

[0041] In summary, the server or intelligent robot sweat-releasing heat dissipation method and system provided by the application can absorb and convert heat: the heat generated by the equipment is transferred to the moisture-wicking and sweat-releasing material, which promotes the water in the material to change from solid or liquid state to gaseous state, thereby absorbing a large amount of heat. The evaporated water vapor is quickly released to the environment through the micropores on the surface of the material, taking the heat away from the equipment and achieving heat dissipation. The intelligent control module continuously monitors the temperature of the equipment and adjusts the physical stimulation parameters such as electric field and magnetic field according to the preset strategy to control the moisture absorption and release rate of the moisture-wicking and sweat-releasing material, so that the temperature of the equipment can be maintained within the set range. Liquid recovery and circulation: the evaporated water vapor condenses into liquid droplets when it encounters cold outside the equipment, which are collected by the liquid collecting tank. After being cooled by the cooling device, the liquid droplets are re-injected into the moisture-wicking and sweat-releasing material, forming a liquid circulation, which overcomes the dependence on the environment, high cost and long-term reliability problems of the traditional heat dissipation method.

The delivery pipeline is also connected to a cooling device and a moisture-wicking material, so that the cooled liquid is re-injected into the moisture-wicking material to form a closed-loop or semi-closed-loop liquid circulation. The protective encapsulation module includes a waterproof and breathable membrane or microporous ceramic, which is wrapped around the outside of the moisture-wicking material and has a breathable channel at the location corresponding to the evaporation area of ​​the moisture-wicking material. At the same time, an airflow guiding channel is set in the area inside the server or intelligent robot corresponding to the protective encapsulation structure to exhaust the gas generated by the evaporation of the moisture-wicking material to the outside of the device.
