Description

Technical Field

[0001] This invention relates to a heat dissipation component, specifically a high-efficiency heat dissipation component and method for an air-source heat pump evaporator, belonging to the field of heat pump evaporator technology. Background Technology

[0002] As a highly efficient and energy-saving heat transfer device, the performance and reliability of the core evaporator component of an air source heat pump directly determine the overall energy efficiency and operational stability of the unit. Key electronic components of the heat pump drive, such as the inverter module and controller, continuously generate heat during operation. Poor heat dissipation will lead to performance degradation, shortened lifespan, or even shutdown. Therefore, efficient heat dissipation technology for heat pump drive components has always been a key focus of industry research and development. Existing technical solutions mainly focus on optimizing a single heat dissipation path. A common approach is forced air cooling, using fans and air ducts to dissipate heat from the heat-generating components through overall convection. For example, one technology for gas evaporators uses a rectangular frame with air inlets, outlets, and a blower assembly to enhance airflow and improve heat dissipation. This approach is structurally simple, but its heat dissipation capacity is greatly affected by ambient temperature and it lacks specificity for localized hot spots, resulting in a bottleneck in heat dissipation efficiency. Another approach is to use liquid cooling technology, utilizing coolant to directly contact or conduct heat through the substrate. For example, the variable frequency heat pump unit and heat dissipation control method disclosed in CN120627461A reduces the impact on the main refrigeration cycle by drawing liquid refrigerant from the receiver and allowing it to flow through a heat dissipation pipeline specially configured for the variable frequency drive module. Although this solution improves heat dissipation efficiency, it still relies on the main refrigeration system, with complex piping and precise control logic, resulting in high system coupling and increased design and maintenance complexity.

[0003] With increasing energy-saving requirements, the recovery and utilization of waste heat generated during heat dissipation has gradually attracted attention. Some independent waste heat recovery attempts have emerged in existing technologies. For example, a dual-condition system based on indoor gas waste heat recovery, disclosed in CN220507300U, recovers flue gas condensation heat through an independent heat exchange chamber to enhance the heating capacity of the heat pump. However, most of these waste heat recovery systems are post- or bypass modules independent of the main heat dissipation unit, and are not integrated with the core electronic device's heat dissipation process. They fail to solve a fundamental problem: the heat lost from the heat pump drive components carries low-grade "waste heat" on its carriers (such as heated coolant and hot air), making collection difficult and resulting in low recovery value and system redundancy.

[0004] In summary, current heat dissipation technology for air source heat pump drive components faces three major challenges: First, a single heat dissipation mode (pure air cooling or pure liquid cooling) cannot simultaneously meet the needs of overall temperature control and local hotspot elimination, thus limiting its heat dissipation efficiency. Second, efficient liquid cooling solutions (such as those utilizing system refrigerant) are often deeply coupled with the main system, increasing system complexity and failure risks. Third, although there is awareness of waste heat recovery, existing recovery solutions are disconnected from the core heat dissipation process, failing to construct a continuous and compact collaborative system from "efficient heat dissipation" to "waste heat collection" and then to "energy conversion." Therefore, there is an urgent need for an innovative heat dissipation component that can break down the barriers between different heat dissipation methods and seamlessly integrate the heat dissipation terminal with the energy recovery starting point, thereby ensuring extremely high operational reliability of the drive components while achieving comprehensive cascade utilization of system energy. Summary of the Invention

[0005] The purpose of this invention is to provide a high-efficiency heat dissipation component and heat dissipation method for an air-source heat pump evaporator in order to solve at least one of the above-mentioned technical problems.

The heat pump drive is disposed between the upper cover and the bottom plate, and liquid cooling grooves are provided on the inner sides of both the upper cover and the bottom plate. Symmetrical drive limit seats are provided on both sides of the liquid cooling grooves provided on the inner sides of the upper cover and the bottom plate.

[0008] As a further embodiment of the present invention: the air intake pipe is connected to the cavity opened on one side plate, and the inner side of the side plate is provided with a plurality of air intake holes; the exhaust pipe is connected to the cavity opened on the opposite side plate, and the inner side of the side plate is provided with a plurality of air guide grooves.

[0009] As a further aspect of the present invention: several groups of air inlets are vertically arranged on the inner side of one of the side plates, and the cold air introduced by each group of air inlets is aligned with the installation gap of the heat pump drive component inside the housing assembly.

[0010] As a further aspect of the present invention: the air guide groove is vertically opened on the inner side of the other side plate, and each air guide groove is configured in a one-to-one correspondence with each group of air inlets.

[0011] As a further embodiment of the present invention: a heat insulation pad is provided between the thermoelectric generator box and the base plate, the thermoelectric generator is horizontally arranged inside the thermoelectric generator box, and the thermoelectric generator is electrically connected to an external storage battery.

[0012] As a further aspect of the present invention: a number of coolant fluid pipes are uniformly arranged in the liquid cooling tank opened in the upper cover and the bottom plate, and the two ends of the number of coolant fluid pipes are respectively connected to the inlet pipe and the outlet pipe through multi-port pipes. The middle of the inlet pipe and the outlet pipe are detachably installed with telescopic hoses.

[0013] As a further aspect of the present invention: the interior of the low-temperature chamber is provided with a plurality of uniformly distributed low-temperature coolant input pipes, and the two sides of the low-temperature chamber are connected to a low-temperature gas inlet port that is connected to an external low-temperature gas storage tank and a low-temperature gas inlet port that is connected to an inlet pipe. The other two sides of the high-temperature chamber are provided with a low-temperature coolant inlet port that is connected to an external low-temperature coolant storage tank and a low-temperature coolant inlet port that is connected to an inlet pipe. The two ends of the plurality of low-temperature coolant input pipes are respectively connected to the low-temperature coolant inlet port and the low-temperature coolant inlet port through multi-port pipes.

[0014] As a further embodiment of the present invention: the two sides of the high-temperature chamber are connected to a high-temperature gas outlet joint connected to an exhaust pipe and a high-temperature gas exhaust port for discharging gas. The other two sides of the high-temperature chamber are provided with a high-temperature coolant outlet port connected to a drain pipe and a high-temperature coolant drain port connected to a high-temperature coolant storage tank. The two ends of several high-temperature coolant output pipes are respectively connected to the high-temperature coolant outlet port and the high-temperature coolant drain port through multi-port pipes.

[0015] A heat dissipation method for an air source heat pump evaporator includes a high-efficiency heat dissipation component and a heat pump drive component for heat dissipation of the air source heat pump evaporator. The heat dissipation method includes the following steps: Step 1: Connect the external cryogenic coolant storage tank to the cryogenic coolant inlet interface to supply cryogenic coolant into the cryogenic coolant input pipe. At the same time, connect the external cryogenic gas storage tank to the cryogenic gas inlet interface to introduce cryogenic gas into the cryogenic chamber. When cryogenic coolant and cryogenic gas are introduced into the cryogenic chamber at the same time, a cryogenic area is formed on one side of the thermoelectric generator. Step 2: The low-temperature coolant in the low-temperature coolant inlet pipe is transported to the coolant fluid pipe through the inlet pipe, so that the coolant flows through multiple pipes from the upper and lower sides of the heat pump drive unit. At the same time, the low-temperature gas in the low-temperature chamber is transported to the housing assembly through the air inlet pipe, and the cold air introduced is directed to the gap between adjacent heat pump drive units and the outer edges of the two outermost heat pump drive units through the air inlet holes. Step 3: After the coolant in the coolant fluid pipe absorbs heat and heats up, it is transported to the high-temperature coolant output pipe through the drain pipe. At the same time, the flowing air in the shell assembly that heats up due to heat removal is collected by the air guide groove and transported to the high-temperature chamber through the exhaust pipe. This allows a high-temperature area to be formed on the other side of the thermoelectric generator when both high-temperature coolant and high-temperature gas are introduced into the high-temperature chamber. Step 4: The thermoelectric generator produces electricity when there is a temperature difference on both sides, and the electricity is stored in the battery and used to power other electrical equipment. Step 5: The high-temperature coolant introduced into the high-temperature coolant outlet pipe is discharged through the high-temperature coolant drain port and collected in the high-temperature coolant storage tank. At the same time, the high-temperature gas introduced into the high-temperature chamber is discharged through the high-temperature gas exhaust port.

[0016] The beneficial effects of this invention are: 1. This invention constructs a highly efficient and synergistic composite heat dissipation system by combining the forced convection of the first heat dissipation module with the conductive heat transfer of the second heat dissipation module. The first module, through the directional airflow formed by the intake and exhaust pipes, can provide full-area heat dissipation for the heat pump drive components within the housing assembly, quickly removing heat distributed over a large area. Simultaneously, the second module, through coolant fluid pipes arranged close to the key parts of the drive components, utilizes the high thermal conductivity of liquid cooling to provide precise and efficient cooling to specific areas with high power density and prone to localized hotspots. This air-liquid synergistic strategy overcomes the limitations of single heat dissipation methods, achieving a perfect balance between overall uniform heat dissipation and localized targeted cooling, thereby greatly improving the reliability and heat dissipation limit of the heat dissipation system and ensuring the long-term stable operation of the heat pump drive components under harsh operating conditions.

[0017] 2. This invention incorporates a waste heat recovery and power generation module. High-temperature gas carrying a large amount of low-grade waste heat, discharged from the first and second heat dissipation modules, along with high-temperature coolant, is concentrated and introduced into its high-temperature chamber. Meanwhile, an initial low-temperature medium for heat dissipation is introduced into its low-temperature chamber. This utilizes the stable and significant temperature difference established across the thermoelectric generator to directly generate electricity. This allows waste heat that would otherwise be wasted in the environment to be efficiently recovered and converted into useful electrical energy, which can be stored or supplied to the system itself. This significantly improves the overall energy efficiency of the entire air source heat pump system, aligning with advanced green and energy-saving concepts. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 like Figures 1 to 7 As shown, a high-efficiency heat dissipation component and heat dissipation method for an air source heat pump evaporator includes a housing assembly, a heat pump drive 4 for the air source heat pump evaporator is installed inside the housing assembly, and a first heat dissipation module, a second heat dissipation module and a waste heat recovery power generation module are integrated on the housing assembly. The first heat dissipation module dissipates heat from the heat pump drive unit 4 in a forced convection manner, including an intake pipe 8 that introduces low-temperature gas into the housing assembly and an exhaust pipe 10 that exhausts the gas that has absorbed heat and been heated out of the housing assembly. The second heat dissipation module dissipates heat to a specific area of ​​the heat pump drive component 4 by conduction heat exchange, including a coolant fluid pipe 14 installed in the housing assembly, an inlet pipe 7 that introduces low-temperature coolant into the coolant fluid pipe 14, and a drain pipe 9 that discharges the coolant after absorbing heat and raising its temperature from the coolant fluid pipe 14. The waste heat recovery power generation module is located at the bottom of the shell assembly. It includes a thermoelectric generator box 6 and a thermoelectric generator plate 63 located inside the box. The thermoelectric generator box 6 is divided into two independent and sealed low-temperature chambers 61 and high-temperature chambers 62 by the thermoelectric generator plate 63. The low-temperature chamber 61 is provided with several uniformly distributed low-temperature coolant inlet pipes 64 and low-temperature gas is circulated inside the low-temperature chamber 61. The high-temperature chamber 62 is provided with several uniformly distributed high-temperature coolant outlet pipes 65 and high-temperature gas is circulated inside the high-temperature chamber 62.

[0022] The first heat dissipation module, through a forced convection system including an intake pipe 8 and an exhaust pipe 10, can quickly and evenly remove the overall heat generated by the heat pump drive component 4 using flowing low-temperature gas, achieving large-area active air cooling with high heat dissipation efficiency and ease of implementation. The second heat dissipation module, through a liquid cooling system including a coolant fluid pipe 14, a liquid inlet pipe 7, and a liquid outlet pipe 9, directly and densely dissipates heat to specific high-temperature areas of the heat pump drive component 4 through conduction heat transfer. This contact heat dissipation method has extremely high heat transfer efficiency and can effectively address local hotspot issues, complementing the first module. The waste heat recovery power generation module, through a unique structure including a thermoelectric generator box 6 and a thermoelectric generator plate 63, centrally recovers the waste heat from the high-temperature gas and high-temperature coolant discharged from the first and second heat dissipation modules. It uses the stable temperature difference established by the low-temperature chamber 61 and the high-temperature chamber 62 to drive the thermoelectric generator plate 63 to generate electricity, realizing the tiered utilization of waste heat energy and improving the overall energy utilization rate of the entire system.

[0023] Example 2 In addition to all the technical features included in Embodiment 1, this embodiment also includes: The housing assembly includes an upper cover 1 at the top, a bottom plate 3 at the bottom, and a side plate 2 connecting the upper cover 1 and the bottom plate 3. The heat pump drive 4 is placed between the upper cover 1 and the bottom plate 3. Liquid cooling grooves 13 are provided on the inner sides of both the upper cover 1 and the bottom plate 3. Symmetrical drive component limiting seats 12 are provided on both sides of the liquid cooling grooves 13 on the inner sides of the upper cover 1 and the bottom plate 3. The liquid cooling grooves 13 on the inner sides of the upper cover 1 and the bottom plate 3 provide a precise and stable installation space and flow channel for the coolant fluid pipes 14 of the second heat dissipation module, ensuring close thermal contact between the liquid cooling system and the heat pump drive 4. The symmetrically arranged drive component limiting seats 12 can securely clamp and position the heat pump drive 4 from the upper and lower sides, preventing it from shifting due to vibration or airflow impact during operation, and ensuring the long-term reliability of the heat dissipation assembly.

[0024] Furthermore, the intake pipe 8 is connected to the cavity 21 opened on one side plate 2, and the inner side of the side plate 2 is provided with several air inlets 22. The exhaust pipe 10 is connected to the cavity 21 opened on the other side plate 2, and the inner side of the side plate 2 is provided with several air guide grooves 23. By connecting the intake pipe 8 and the exhaust pipe 10 to the cavities 21 of the two side plates 2 respectively, and designing the airflow distribution to enter through the air inlet 22 on one side and exit through the air guide groove 23 on the other side, a directional and continuous through-flow airflow channel is constructed, which allows cold air to be forced to penetrate the entire internal space of the housing assembly laterally, avoiding airflow short-circuiting or the formation of vortex dead zones, ensuring that the airflow flowing through the surface of the heat pump drive component 4 is fully covered and the path is effective, improving the overall efficiency and uniformity of forced convection heat dissipation, and making heat exchange more complete.

[0025] Furthermore, several groups of air inlets 22 are vertically arranged on the inner side of one of the side plates 2. The cold air entering through each group of air inlets 22 is aligned with the mounting gap of the heat pump drive unit 4 inside the housing assembly. By vertically grouping the air inlets 22 and ensuring that the cold air entering through each group is precisely aligned with the mounting gap between the heat pump drive units 4, targeted airflow delivery is achieved. This allows the cooling airflow to be directly guided to the core heat exchange area, which is the most difficult to dissipate heat when the heat pump drive units 4 are stacked or arranged, enhancing the direct contact between the airflow and the side surface of the heat-generating element and the intensity of convective heat transfer. This solves the problem in traditional air cooling where airflow tends to flow through the periphery and is difficult to penetrate into the internal gaps of the device.

[0026] Furthermore, the air guide groove 23 is vertically opened on the inner side of the other side plate 2, and each air guide groove 23 is set in a one-to-one correspondence with each group of air inlets 22, ensuring that the hot air that has absorbed heat from a specific group of air inlets 22 can be efficiently collected by the corresponding air guide groove 23 and discharged to the exhaust pipe 10, avoiding mutual interference, mixing or backflow of hot airflows from different paths in the housing.

[0027] Furthermore, a heat insulation pad 5 is installed between the thermoelectric generator 6 and the base plate 3. The thermoelectric generator 63 is horizontally positioned inside the thermoelectric generator 6 and is electrically connected to an external battery. The heat insulation pad 5 between the thermoelectric generator 6 and the base plate 3 effectively prevents heat conducted from the upper shell assembly from directly interfering with the temperature field at the bottom of the thermoelectric generator 6, protecting the low-temperature environment of the low-temperature cavity 61 from interference, and ensuring that the thermoelectric generator 63 can maintain the largest possible stable temperature difference on both sides, thereby improving power generation efficiency. The horizontal placement of the thermoelectric generator 63 facilitates natural thermal stratification of the fluid within its two cavities, stabilizing the temperature distribution.

[0028] Furthermore, several coolant fluid pipes 14 are evenly arranged within the liquid cooling tank 13 formed by the upper cover 1 and the bottom plate 3. Both ends of each coolant fluid pipe 14 are connected to the inlet pipe 7 and the outlet pipe 9 via multi-port pipes. A removable flexible hose 11 is installed in the middle of both the inlet pipe 7 and the outlet pipe 9. The even arrangement of multiple coolant fluid pipes 14 within the liquid cooling tank 13, connected in parallel via multi-port pipes, allows the low-temperature coolant to be distributed into multiple fine streams, simultaneously covering a wide area on the upper and lower sides of the heat pump drive component 4. This significantly increases the contact area and heat exchange uniformity between the liquid cooling system and the heat-generating element, thereby improving the overall liquid cooling efficiency. The removable flexible hose 11 in the middle of the inlet pipe 7 and the outlet pipe 9 greatly improves the system's installation flexibility and maintainability. The flexible hose 11 can compensate for installation errors and alleviate stress caused by thermal expansion and contraction or vibration.

[0029] Furthermore, the cryogenic chamber 61 is equipped with several uniformly distributed cryogenic coolant inlet pipes 64. Both sides of the cryogenic chamber 61 are connected to a cryogenic gas inlet port 66, which is connected to an external cryogenic gas storage tank, and a cryogenic gas inlet port 67, which is connected to the inlet pipe 8. The other two sides of the high-temperature chamber 62 are equipped with a cryogenic coolant inlet port 610, which is connected to an external cryogenic coolant storage tank, and a cryogenic coolant inlet port 611, which is connected to the inlet pipe 7. Both ends of the several cryogenic coolant inlet pipes 64 are connected to the cryogenic coolant inlet port 610 and the cryogenic coolant inlet port 611 respectively via multi-port pipes. The uniform arrangement of multiple cryogenic coolant inlet pipes 64 within the cryogenic chamber 61, and their connection to the external circulation via the cryogenic coolant inlet port 610 and the cryogenic coolant inlet port 611, allows the cryogenic coolant from the storage tank to flow through the pipes within this chamber before flowing into the inlet pipe 7, thus fully pre-cooling the gas environment within the chamber. Meanwhile, external low-temperature gas and recovered cooling air are introduced through independent low-temperature gas inlet 66 and low-temperature gas outlet 67 respectively. The dual cold sources work together to quickly establish and maintain a low-temperature zone on one side of the thermoelectric generator 63, enhancing the stability and efficiency of thermoelectric power generation.

[0030] Furthermore, the high-temperature chamber 62 is connected to two sides by high-temperature gas outlet joints 68 connected to the exhaust pipe 10 and high-temperature gas exhaust ports 69 for discharging gas. The other two sides of the high-temperature chamber 62 are provided with high-temperature coolant outlet ports 612 connected to the drain pipe 9 and high-temperature coolant drain ports 613 connected to the high-temperature coolant storage tank. Several high-temperature coolant outlet pipes 65 are connected at both ends to the high-temperature coolant outlet ports 612 and 613 via multi-port pipes. Multiple high-temperature coolant outlet pipes 65 are evenly arranged within the high-temperature chamber 62 and connected to the external circulation via the high-temperature coolant outlet ports 612 and 613, ensuring that the heat of the high-temperature coolant discharged from the main heat dissipation circulation is retained within the chamber before being finally discharged back into the storage tank. Simultaneously, high-temperature gas discharged from the shell is introduced and finally discharged through the high-temperature gas outlet joints 68 and high-temperature gas exhaust ports 69. This dual heat source action efficiently establishes and maintains a high-temperature zone on the other side of the thermoelectric generator 63. The synergistic heating of the high-temperature coolant output pipe 65 and the high-temperature gas ensures sufficient and stable hot-end temperature, thereby forming a significant and lasting temperature difference on both sides of the thermoelectric generator 63 together with the low-temperature cavity 61, maximizing the amount of waste heat recovered for power generation.

[0031] Example 3 A heat dissipation method for an air source heat pump evaporator includes a high-efficiency heat dissipation component and a heat pump drive 4 for the air source heat pump evaporator to dissipate heat. The heat dissipation method includes the following steps: Step 1: Connect the external cryogenic coolant storage tank to the cryogenic coolant inlet port 610 to supply cryogenic coolant into the cryogenic coolant inlet pipe 64. At the same time, connect the external cryogenic gas storage tank to the cryogenic gas inlet port 66 to introduce cryogenic gas into the cryogenic chamber 61. When cryogenic coolant and cryogenic gas are introduced into the cryogenic chamber 61 at the same time, a cryogenic area is formed on one side of the thermoelectric generator 63. Step 2: The low-temperature coolant in the low-temperature coolant inlet pipe 64 is transported to the coolant fluid pipe 14 through the liquid inlet pipe 7, so that the coolant flows through multiple pipes from the upper and lower sides of the heat pump drive unit 4. At the same time, the low-temperature gas in the low-temperature chamber 61 is transported to the housing assembly through the air inlet pipe 8, and the cold air introduced is directed to the gap between adjacent heat pump drive units 4 and the outer edges of the two outermost heat pump drive units 4 through the air inlet 22. Step 3: After the coolant in the coolant fluid pipe 14 absorbs heat and heats up, it is transported to the high-temperature coolant output pipe 65 through the drain pipe 9. At the same time, the flowing air in the shell assembly that heats up due to heat removal is collected by the air guide groove 23 and transported to the high-temperature chamber 62 through the exhaust pipe 10. This allows the high-temperature chamber 62 to form a high-temperature area on the other side of the thermoelectric generator 63 when high-temperature coolant and high-temperature gas are simultaneously introduced. Step 4: The thermoelectric generator 63 generates electrical energy when there is a temperature difference on both sides, and the energy is stored in the battery and used to power other electrical equipment. Step 5: The high-temperature coolant introduced into the high-temperature coolant output pipe 65 is discharged through the high-temperature coolant drain port 613 and collected in the high-temperature coolant storage tank. At the same time, the high-temperature gas introduced into the high-temperature chamber 62 is discharged through the high-temperature gas exhaust port 69.

[0032] Working principle: When this high-efficiency heat dissipation component is working, the initial low-temperature medium is first provided by the low-temperature cavity 61 of the waste heat recovery power generation module. The low-temperature gas introduced into the cavity and the low-temperature coolant flowing through the low-temperature coolant inlet pipe 64 together establish a low-temperature zone on one side of the thermoelectric generator 63. The low-temperature coolant is pumped into the coolant fluid pipe 14 of the second heat dissipation module through the inlet pipe 7. These pipes are closely attached to the liquid cooling tanks 13 on the upper and lower surfaces of the heat pump drive component 4, and efficiently absorb the concentrated heat generated in specific areas (such as chips) of the heat pump drive component 4 through direct heat conduction.

[0033] Simultaneously, the first heat dissipation module activates, and low-temperature gas is introduced from the low-temperature chamber 61 through the intake pipe 8 into the cavity 21 on one side of the housing assembly. This gas then forms a directional airflow through the intake port 22. This cold air directly blows across the mounting gaps between the heat pump drive components 4 and their outer sides, carrying away a large amount of heat dissipated by the entire assembly through forced convection. The high-temperature coolant, after absorbing heat, is discharged through the drain pipe 9, while the heated gas is collected by the opposite air guide groove 23 and discharged through the exhaust pipe 10. These high-temperature media carrying waste heat are collectively introduced into the high-temperature chamber 62 of the waste heat recovery power generation module; the high-temperature coolant flows through the high-temperature coolant output pipe 65, and the high-temperature gas fills the cavity, both forming a stable high-temperature zone on the other side of the thermoelectric generator 63. Thus, the significant temperature difference between the two sides of the thermoelectric generator 63 generates direct current electricity, which can be stored or utilized.

[0034] The high-temperature coolant and gas that have completed heat exchange are discharged through the high-temperature coolant drain port 613 and the high-temperature gas exhaust port 69, respectively.

10. A heat dissipation method for an air-source heat pump evaporator, comprising a high-efficiency heat dissipation component and a heat pump drive (4) for heat dissipation of the air-source heat pump evaporator, characterized in that: The heat dissipation method includes the following steps: Step 1: Connect the external cryogenic coolant storage tank to the cryogenic coolant inlet interface (610) to deliver cryogenic coolant into the cryogenic coolant input pipe (64). At the same time, connect the external cryogenic gas storage tank to the cryogenic gas inlet interface (66) to introduce cryogenic gas into the cryogenic cavity (61). When cryogenic coolant and cryogenic gas are introduced into the cryogenic cavity (61) at the same time, a cryogenic area is formed on one side of the thermoelectric generator (63). Step 2: The low-temperature coolant in the low-temperature coolant inlet pipe (64) is transported to the coolant fluid pipe (14) through the inlet pipe (7), so that the coolant flows through multiple pipes from the upper and lower sides of the heat pump drive unit (4). At the same time, the low-temperature gas in the low-temperature chamber (61) is transported to the housing assembly through the air inlet pipe (8), and the cold air introduced is directed to the gap between adjacent heat pump drive units (4) and the outer side of the two outermost heat pump drive units (4) through the air inlet hole (22) to blow. Step 3: After the coolant in the coolant fluid pipe (14) absorbs heat and heats up, it is transported to the high-temperature coolant output pipe (65) through the drain pipe (9). At the same time, the flowing air in the shell assembly that heats up due to heat removal is collected by the air guide groove (23) and transported to the high-temperature chamber (62) through the exhaust pipe (10). This allows the high-temperature chamber (62) to form a high-temperature area on the other side of the thermoelectric generator (63) when high-temperature coolant and high-temperature gas are simultaneously introduced. Step 4: The thermoelectric generator (63) generates electrical energy when there is a temperature difference on both sides, and the energy is stored in the battery and used to power other electrical equipment. Step 5: The high-temperature coolant introduced into the high-temperature coolant output pipe (65) is discharged through the high-temperature coolant drain port (613) and collected in the high-temperature coolant storage tank. At the same time, the high-temperature gas introduced into the high-temperature chamber (62) is discharged through the high-temperature gas exhaust port (69).
