Description

Technical Field

[0001] This invention relates to a high-efficiency heat dissipation type energy storage container, belonging to the field of energy storage container technology. Background Technology

[0002] As an integrated and modular energy storage device, energy storage containers have been widely used in fields such as new energy grid connection, industrial and commercial energy storage, and grid peak shaving. Currently, the battery clusters inside energy storage containers mainly use air cooling or liquid cooling for thermal management: air cooling systems have a simple structure and low cost, but poor heat dissipation uniformity and limited heat exchange efficiency; liquid cooling systems have higher heat dissipation efficiency and can better adapt to high-power charging and discharging conditions.

[0003] However, when using existing heat dissipation methods in hot summer, the external ambient temperature is high, the temperature difference between the air-cooled condenser and the outside is small, and the heat dissipation effect is greatly reduced. The outdoor heat exchanger of the liquid cooling system is also easily affected by the high temperature environment. In order to meet the battery operating temperature requirements, the operating power of the fan and water pump needs to be greatly increased, resulting in a significant increase in system energy consumption. Moreover, it is still difficult to stabilize the battery temperature in the optimal operating range, which can easily lead to problems such as local overheating and excessively rapid temperature rise, affecting battery safety and service life.

[0004] To address these issues, a high-efficiency heat dissipation type energy storage container was designed. Summary of the Invention

[0005] The main objective of this invention is to provide a high-efficiency heat dissipation energy storage container. By installing underground-mountable air ducts and water-cooled radiators at the bottom of the container, which are then coordinated with the water pump and fan of the cold source delivery mechanism, integrated and synergistic heat dissipation of the liquid and air cooling systems is achieved. This effectively avoids interference from high temperatures in summer on the heat exchange process, significantly improving heat dissipation efficiency. Simultaneously, the liquid and air cooling systems can operate independently. In winter, geothermal energy can be used to create a suitable temperature environment for battery operation within the container, effectively ensuring battery energy storage performance and avoiding the adverse effects of low temperatures on battery energy storage capacity. By incorporating a guide component consisting of a servo motor, mounting rod, and baffle in the cold source delivery mechanism, the cold source utilization path of the air cooling system can be flexibly switched according to the external ambient temperature. When the ambient temperature is lower than the underground temperature, external cold sources can be used directly for heat dissipation. When the ambient temperature is higher, underground cold sources can be used for cooling, achieving efficient adaptation and utilization of cold sources. This significantly improves the equipment's adaptability to different ambient temperatures and further enhances the cooling effect. By opening a groove at the bottom of the enclosure, the air duct and water-cooled radiator can be stored in the groove in the initial state, effectively saving space. At the same time, in conjunction with the lifting mechanism inside the enclosure, which consists of a first guide groove, a first slider, a screw, a lifting motor, a shaft, a first bevel gear, a second bevel gear, a second guide groove, and a second slider, the lifting and lowering of the air duct and water-cooled radiator can be easily adjusted during equipment installation without additional auxiliary disassembly and assembly operations, greatly improving the convenience of equipment installation and use.

[0024] This invention provides a high-efficiency heat dissipation energy storage container. By installing underground-layout air ducts and water-cooled radiators at the bottom of the container, and cooperating with the water pump and fan of the cold source delivery mechanism, the integrated and coordinated heat dissipation of liquid cooling and air cooling systems is achieved. This effectively avoids the interference of high-temperature external environment in summer on the heat exchange process, significantly improving heat dissipation efficiency. At the same time, the liquid cooling system and air cooling system can operate independently. In winter, geothermal energy can be used to create a temperature environment suitable for battery operation inside the container, effectively ensuring the battery's energy storage performance and avoiding the adverse effects of low temperature environment on battery energy storage capacity.

[0025] By setting a guide component consisting of a servo motor, mounting rod, and baffle in the cold source conveying mechanism, the cold source utilization path of the air-cooling system can be flexibly switched according to the ambient temperature. When the ambient temperature is lower than the underground temperature, the external cold source can be directly used to complete the heat dissipation. When the ambient temperature is higher, the underground cold source can be switched to cool down. This achieves efficient adaptation and utilization of the cold source, greatly improves the equipment's adaptability to different ambient temperatures, and further enhances the cooling effect.

[0026] By creating a groove at the bottom of the housing, the air duct and water-cooled radiator can be stored in the groove in the initial state, effectively saving space. At the same time, in conjunction with the lifting mechanism inside the housing, which consists of a first guide groove, a first slider, a screw, a lifting motor, a shaft, a first bevel gear, a second bevel gear, a second guide groove, and a second slider, the lifting and adjusting of the air duct and water-cooled radiator can be easily achieved during equipment installation without the need for additional auxiliary disassembly and assembly operations, greatly improving the convenience of equipment installation and use.

[0053] To enable those skilled in the art to more clearly understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0054] like Figures 1-18 As shown, this embodiment provides a high-efficiency heat dissipation type energy storage container, including a container body 1, and an air duct 3, a water-cooled radiator 8 and a water tank 9 are adapted and housed inside the container body 1.

[0055] In both transport and non-use states, the air duct 3, water-cooled radiator 8, and water tank 9 are all housed inside the housing 1, achieving integrated equipment, significantly reducing the overall space occupied by the equipment, and facilitating transportation and transfer.

[0056] Mounting blocks 2 are vertically slidably installed at both ends of the inner side of the housing 1. The two ends of the air duct 3 slide into the interior of the housing 1 and are fixedly connected to the mounting blocks 2. A lifting mechanism 4 is provided inside the housing 1. The power output end of the lifting mechanism 4 is connected to the mounting blocks 2 to drive the air duct 3, water-cooled radiator 8 and water tank 9 to move up and down in the vertical direction.

[0057] After the equipment is transported to the target installation site, the lifting mechanism 4 drives the installation block 2 to move downward in the vertical direction, thereby driving the air duct 3 fixedly connected to the installation block 2, as well as the water-cooled radiator 8 and water tank 9 that are synchronously linked with the air duct 3 to extend downward in the groove 102 until the air duct 3, the water-cooled radiator 8 and water tank 9 are buried in the underground foundation pit of the site, thus completing the installation of the buried heat exchange components.

[0058] Inside the housing 1, water-cooled plates 10 are arranged in an array, and a drain pipe 11 connects the drain port of the water-cooled plate 10 to the water-cooled radiator 8.

[0059] A hollow plate 6 is provided at the bottom of the box 1, and a number of air holes 7 are evenly opened on the top of the hollow plate 6, which are connected to its hollow inner cavity.

[0060] An air inlet mechanism 5 is provided at one end of the housing 1, which is used to deliver external air into the air duct 3 when the equipment is in operation;

[0061] A cold source conveying mechanism 12 is provided at the end of the housing 1 away from the air intake mechanism 5. It is used to receive the coolant after underground heat exchange and convey it to the water-cooled plate 10. It can also selectively convey the air source after underground heat exchange or the external direct air source to the hollow plate 6.

[0062] In the liquid cooling heat dissipation cycle, the coolant stored in the water tank 9 is cooled down by underground heat exchange through the water-cooled radiator 8, and then transported to the array of water-cooled plates 10 inside the housing 1 through the cold source conveying mechanism 12. The water-cooled plates 10 are attached to the surface of the battery cluster to absorb the heat generated during battery charging and discharging. The heated coolant flows back to the water-cooled radiator 8 through the drain pipe 11, and is cooled down again by underground soil heat exchange before flowing back to the water tank 9, completing the closed liquid cooling cycle. The entire process utilizes the low temperature characteristics of the underground constant temperature layer to cool the coolant, without being affected by the high temperature environment of the outside, which greatly improves the heat exchange efficiency. At the same time, there is no need to install an outdoor condenser, reducing equipment energy consumption.

[0063] In the air-cooled heat dissipation cycle, external air enters the air duct 3 through the air intake mechanism 5. During the flow of the air in the air duct 3, the air exchanges heat with the underground soil and cools down. The cooled low-temperature air is then transported to the cold source conveying mechanism 12, and then to the hollow plate 6 at the bottom of the housing 1. Finally, it is evenly sprayed upward through the air holes 7 evenly opened at the top of the hollow plate 6, forming a uniform cooling airflow from bottom to top inside the housing 1. This airflow fully covers the battery cluster inside the housing 1, carrying away the heat generated by the battery operation and achieving uniform air-cooled heat dissipation. At the same time, the cold source conveying mechanism 12 can selectively switch the air source path according to the ambient temperature. When the ambient temperature is lower than the underground soil temperature, it can directly draw external ambient air and transport it to the hollow plate 6 to complete the air-cooled heat dissipation. When the ambient temperature is higher than the underground soil temperature, it switches to drawing underground cold source air that has been heat-exchanged through the air duct 3 for heat dissipation, achieving efficient air-cooling adaptation under all temperature conditions and further reducing the system's operating energy consumption.

[0064] The liquid cooling and air cooling cycles can operate independently or synchronously, and can be flexibly adjusted according to the battery's charging and discharging power and ambient temperature. In low-temperature winter environments, the geothermal characteristics of the underground constant temperature layer can be utilized to heat the air source and coolant through the air duct 3 and water-cooled radiator 8, respectively. Then, the heat is transferred to the inside of the housing 1 through the air cooling and liquid cooling cycles, providing the battery with a suitable operating temperature. This avoids the problem of decreased battery charging and discharging efficiency and reduced energy storage capacity caused by low-temperature environments, ensuring stable operation of the battery under all-season conditions.

[0065] In this embodiment, as Figure 6 and Figure 8 As shown, a groove 102 is provided at the bottom of the box 1, and a bottom plate 103 is provided at the bottom of the groove 102. The bottom plate 103 covers and blocks the bottom opening of the groove 102. The air duct 3, the water-cooled radiator 8 and the water tank 9 are all stored in the groove 102, and their bottom ends are all fixedly connected to the bottom plate 103.

[0066] On the one hand, the bottom opening of the groove 102 is covered and blocked by the base plate 103, which isolates the inside of the box 1 from the external environment when not in use, and prevents dust, moisture and debris from entering the groove 102 and causing pollution or corrosion to the buried heat exchange components; on the other hand, the base plate 103 provides unified support and limit for the air duct 3, water-cooled radiator 8 and water tank 9, ensuring that the three rise and fall synchronously during the lifting process.

[0067] The bottom of the housing 1 is also fixedly provided with multiple support seats 101. The multiple support seats 101 provide stable support for the housing 1 during the transportation, storage and installation of the equipment, so that sufficient lifting space is reserved between the bottom of the housing 1 and the ground.

[0068] The top of the housing 1 is provided with an air vent 13, and the top of the air vent 13 is provided with a cover 14. The hot air discharged by the air cooling is discharged from the air vent 13, and the cover 14 is used to prevent rain and dust from entering.

[0069] In this embodiment, as Figure 4 As shown, there are two sets of air ducts 3. The ends of the two sets of air ducts 3 pass through the mounting blocks 2 on the corresponding sides and fit against the inner end face of the housing 1 to achieve radial limit of the air ducts 3 and prevent radial movement of the air ducts 3 during the lifting process. At the same time, after the equipment is installed, the mounting blocks 2 are moved down to the bottom of the housing 1. One end of the air duct 3 is connected to the air inlet hole 502 of the air inlet mechanism 5, and the other end is connected to the exhaust hole 1206 of the cold source conveying mechanism 12 to ensure the docking accuracy of the air duct 3 with the air inlet mechanism 5 and the cold source conveying mechanism 12, and to ensure the airtightness of the air passage connection.

[0070] The water-cooled radiator 8 and the water tank 9 are both located between the two sets of air ducts 3, making the structure of the entire buried heat exchange assembly more compact.

[0071] The outer wall of the air duct 3 is evenly provided with several heat dissipation fins along its length, which greatly increases the contact area between the air duct 3 and the underground soil and enhances the heat exchange efficiency between the air source and the underground soil.

[0072] In this embodiment, as Figure 9 and Figure 14 As shown, the air intake mechanism 5 includes an air hood 501, an air intake hole 502, a first side air vent 503, and a first filter plate 504. The air hood 501 is fixedly installed on the outer side of one end of the housing 1. An air intake hole 502 communicating with the inside of the air hood 501 is opened at the lower end of the housing 1 near the air hood 501. The first filter plate 504 is installed inside the air hood 501. A first side air vent 503 is opened at the top of the outer side of the air hood 501.

[0073] When the equipment is running, ambient air enters the air hood 501 through the first side air vent 503, is filtered by the first filter plate 504, and then enters the air duct 3 through the air inlet 502 at the end of the housing 1, thus completing the input of the air source.

[0074] In this embodiment, as Figure 12 and Figure 15 As shown, the lifting mechanism 4 includes a first guide groove 401, a first slider 402, a screw 403, and a rotary drive assembly. The first guide groove 401 is vertically opened at the middle position of both ends of the inner side of the housing 1. A first slider 402 is vertically slidably installed in each set of first guide grooves 401. The first guide groove 401 provides guidance and limit for the sliding of the first slider 402, preventing the first slider 402 from rotating circumferentially with the screw 403 and ensuring the straightness of the sliding. The first slider 402 is fixedly connected to the mounting block 2 on the corresponding side. The screw 403 is rotatably installed between the upper and lower ends of the first guide groove 401. The screw 403 is threadedly engaged with the first slider 402. A rotary drive assembly is provided at the inner top of the housing 1. The rotary drive assembly is used to synchronously drive the two sets of screws 403 to rotate synchronously.

[0075] During the lifting operation, the rotary drive assembly synchronously drives the two sets of screws 403 at both ends of the housing 1 to rotate synchronously. During the rotation of the screws 403, the first slider 402 is driven to slide vertically along the first guide groove 401 through the threaded engagement. During the sliding of the first slider 402, the mounting block 2 fixedly connected to it is driven to lift synchronously. Then, the mounting block 2 drives the air duct 3, water-cooled radiator 8 and water tank 9 to complete the lifting action.

[0076] In this embodiment, as Figure 15 As shown, the rotary drive assembly includes a lifting motor 404, a shaft 405, a first bevel gear 406, and a second bevel gear 407. The lifting motor 404 is fixedly installed at the end of the housing 1. The lifting motor 404 is a forward and reverse reversible motor, which can control the descent and extension and the rise and retraction of the buried heat exchange assembly by forward and reverse rotation, respectively. Its output end is coaxially connected to the shaft 405. The shaft 405 is arranged along the length direction of the housing 1. The first bevel gear 406 is fixedly installed at both ends of the shaft 405. The second bevel gear 407 is fixedly installed at the top of both sets of screws 403. The second bevel gear 407 meshes with the first bevel gear 406 on the corresponding side.

[0077] During lifting operations, the lifting motor 404 starts, driving the shaft 405, which is coaxially connected to its output end, to rotate. During the rotation of the shaft 405, the first bevel gear 406, which is fixed at both ends, rotates synchronously. The first bevel gear 406 drives the second bevel gear 407 on the corresponding side to rotate through meshing transmission, and then drives the screw 403 to rotate synchronously through the second bevel gear 407, thus completing the transmission of lifting power.

[0078] In this embodiment, as Figure 9 and Figure 15 As shown, the inner sidewalls at both ends of the housing 1 are vertically provided with second guide grooves 408, and each set of second guide grooves 408 is slidably equipped with a second slider 409, which is fixedly connected to the mounting block 2 on the corresponding side.

[0079] During the lifting and lowering process of the mounting block 2, the second slider 409 slides vertically along the second guide groove 408 synchronously with the mounting block 2. The second guide groove 408 provides auxiliary guidance for the second slider 409 and forms a double-sided limit with the first guide groove 401, restricting the forward and backward and left and right movement of the mounting block 2, avoiding the mounting block 2 from swaying during the lifting and lowering process, thereby ensuring the smoothness of the lifting and lowering action of the buried heat exchange component and preventing jamming.

[0080] In this embodiment, as Figure 11 , Figure 12 and Figure 13 As shown, the cold source delivery mechanism 12 includes a cold source box 1201, an upper partition 1202, a water pump 1203, a circulation pipe 1204, a liquid inlet pipe 1205, and a gas delivery assembly. The cold source box 1201 is the core supporting shell of the cold source delivery mechanism 12, integrating the liquid cooling delivery system and the gas delivery system into one unit to achieve integrated control of liquid cooling and air cooling. The cold source box 1201 is fixedly installed on the inner side of the box 1 at the end away from the air inlet mechanism 5. The upper partition 1202 is fixedly installed on the inner top of the cold source box 1201, dividing the interior of the cold source box 1201 into independent liquid cooling chambers and air cooling chambers. The water pump 1203 is installed on the top of the upper partition 1202. The water pump 1203 can... By adjusting the rotation speed, the circulation flow rate of the coolant is controlled, thereby adapting to the heat dissipation requirements of the battery under different charging and discharging powers, achieving precise temperature control, and reducing unnecessary energy consumption. The input end of the water pump 1203 is connected to the water tank 9 by a circulation pipe 1204, and the output end of the water pump 1203 is connected to the liquid inlet of the water-cooled plate 10 by a liquid inlet pipe 1205. The interior of the cold source box 1201 is also equipped with an air source delivery component, which is used to deliver cooling air to the hollow plate 6. It can realize the extraction, path switching and delivery of air-cooled air source, and is independent of the liquid cooling delivery system. It can be started and stopped independently, realizing the independent operation and combined operation of the liquid cooling and air cooling systems, and improving the flexibility of equipment thermal management.

[0081] During the liquid cooling cycle, the water pump 1203 starts and draws the coolant from the water tank 9 after heat exchange and cooling by the water-cooled radiator 8 through the circulation pipe 1204. After being pressurized, the coolant is delivered to the water-cooled plate 10 inside the housing 1 through the liquid inlet pipe 1205, providing the water-cooled plate 10 with a continuous low-temperature coolant and ensuring the continuous and stable liquid cooling heat dissipation.

[0082] In this embodiment, as Figure 10 , Figure 13 and Figure 17 As shown, the air supply delivery assembly includes an exhaust port 1206, a lower partition 1207, a middle partition 1208, a through groove 1209, a fan 1210, an exhaust pipe 1211, a second filter plate 1212, a second side air outlet 1213, and a flow guide. The exhaust port 1206 is located below the end of the housing 1 near the cold source box 1201 and is connected to the interior of the cold source box 1201. The lower partition 1207 is fixedly installed at the bottom of the interior of the cold source box 1201, and the middle partition 1208 is fixedly installed in the middle of the interior of the cold source box 1201. The lower partition 1207 and the middle partition 1208 divide the lower part of the cold source box 1201 into an underground air source chamber, a fan installation chamber, and an external air source chamber, providing a structural basis for switching the air source path.

[0083] Both the lower partition 1207 and the middle partition 1208 have through slots 1209. A second filter plate 1212 is installed at the through slot 1209 at the top of the middle partition 1208. The second filter plate 1212 can filter the incoming external air source to remove dust and impurities. A second side air vent 1213 is provided on the outside of the cold source box 1201, which communicates with the top of the inside of the cold source box 1201. An air vent is installed between the middle partition 1208 and the lower partition 1207. The output end of the fan 1210 is connected to the hollow plate 6 by an exhaust pipe 1211. A guide is also provided between the middle partition 1208 and the lower partition 1207. The guide is used to selectively connect the two sets of through slots 1209 to the input end of the fan 1210. The through slots 1209 provide a unique flow path for the air source. With the on / off control of the guide, reliable isolation of the two air source paths can be achieved, and cross-flow between the two air sources can be avoided.

[0084] When using underground cold source air source for heat dissipation, the guide component opens the through groove 1209 on the lower partition 1207 and closes the through groove 1209 on the middle partition 1208. The negative pressure generated by the fan 1210 is transferred to the bottom chamber of the cold source box 1201 through the through groove 1209 of the lower partition 1207. Then, the low-temperature air source after underground heat exchange is drawn from the air guide pipe 3 through the exhaust hole 1206. After the low-temperature air source enters the fan 1210, it is pressurized and transported to the hollow plate 6 through the exhaust pipe 1211, thus completing the air-cooling cycle of the underground cold source air source.

[0085] When external ambient air source is used for heat dissipation, the guide component closes the through groove 1209 on the lower partition 1207 and opens the through groove 1209 on the middle partition 1208. The negative pressure generated by the fan 1210 is transferred to the upper chamber of the cold source box 1201 through the through groove 1209 of the middle partition 1208. Then, the air source in the external environment is directly drawn through the second side air outlet 1213. The air source enters the fan 1210 after being filtered by the second filter plate 1212, and is then transported to the hollow plate 6 through the exhaust pipe 1211 to complete the air-cooling cycle of the external air source.

[0086] In this embodiment, as Figure 12 , Figure 13 and Figure 18 As shown, the flow guide includes a servo motor 1214, a mounting rod 1215, and a baffle 1216. The servo motor 1214 is fixedly installed on the inner side wall of the cold source box 1201, and its output end is coaxially connected to the mounting rod 1215. Two sets of baffles 1216 are symmetrically fixed on the outer side of the mounting rod 1215. The two sets of baffles 1216 are respectively adapted to be inserted into the through groove 1209 on the corresponding side, and the outer wall of the baffle 1216 is in contact with the through groove 1209 and the inner wall of the cold source box 1201.

[0087] When the air source path is switched, the servo motor 1214 starts, driving the mounting rod 1215, which is coaxially connected to its output end, to rotate. During the rotation of the mounting rod 1215, it drives the two sets of baffles 1216, which are symmetrically fixed on its outer side, to deflect synchronously. The baffles 1216 slide against the inner wall of the through groove 1209 and the cold source box 1201. Due to the contact between the outer wall of the baffle 1216 and the cold source box 1201, the two ends can be sealed directly during the rotation, preventing air leakage. When the baffle 1216 is inclined upward and faces the fan 1210, the external air source is connected. When the baffle 1216 is inclined downward and faces the fan 1210, the underground air source is connected, realizing the interlocking control of the opening and closing of the two sets of through grooves 1209, completely avoiding air source crossflow.

[0088] In this embodiment, as Figure 16 As shown, a storage slot 201 is provided at the middle position of the top of the mounting block 2. The storage slot 201 is used to store the drain pipe 11 and the connecting coil at the top of the circulation pipe 1204.

[0089] The storage slot 201 at the top of mounting block 2 provides dedicated storage space for flexible connecting pipes. Since the buried heat exchange component needs to perform lifting and lowering movements, the drain pipe 11 and circulation pipe 1204 need to adopt a retractable flexible coil structure to adapt to the lifting and lowering stroke of the buried heat exchange component. When the buried heat exchange component is in the retracted state, the connecting coil of the drain pipe 11 and circulation pipe 1204 can be completely stored in the storage slot 201, avoiding the squeezing, bending, and wear caused by the exposed pipes, while preventing the pipes from getting tangled on other components, ensuring the smoothness and integrity of the pipes during the lifting and lowering process. When the buried heat exchange component descends and extends, the connecting coil gradually extends from the storage slot 201 to adapt to the lifting and lowering stroke, without causing pulling damage to the pipes, ensuring the long-term stable connection of the liquid cooling circulation pipes.

[0090] During equipment transportation, the buried heat exchange assembly consisting of the air duct 3, water-cooled radiator 8, and water tank 9 is completely housed in the groove 102 at the bottom of the box 1. The bottom plate 103 seals the bottom of the groove 102. The connecting coils of the drain pipe 11 and the circulation pipe 1204 are housed in the storage slot 201 of the mounting block 2. The equipment as a whole has a standard container structure, which is convenient for road and sea transportation. There are no extra protruding parts, avoiding bumps and damage during transportation.

[0091] During the equipment installation phase, the housing 1 is placed stably on the preset installation site using the support base 101. The lifting motor 404 is started, and the lifting motor 404 drives the screws 403 at both ends of the housing 1 to rotate synchronously through the meshing transmission of the shaft 405, the first bevel gear 406, and the second bevel gear 407. Then, through the first slider 402, the mounting block 2 is driven to slide smoothly downward along the first guide groove 401 and the second guide groove 408. The mounting block 2 drives the air duct 3, the water-cooled radiator 8, and the water tank 9 to extend downward synchronously from the groove 102 until they are buried in the underground foundation pit, thus completing the installation of the buried heat exchange components.

[0092] When the equipment operates under high-temperature conditions in summer, it prioritizes underground cold sources for heat dissipation. In the liquid cooling cycle, water pump 1203 starts, driving the coolant to complete a closed-loop circulation between water tank 9, water-cooled radiator 8, and water-cooled plate 10. After the coolant exchanges heat with the low-temperature underground soil in water-cooled radiator 8, it is transported to water-cooled plate 10 to absorb battery heat, achieving efficient liquid cooling heat dissipation unaffected by the high-temperature external environment. In the air cooling cycle, fan 1210 starts, and servo motor 1214 drives baffle 1216 to close the intermediate partition 1208. The through slot 1209 connects to the lower partition 1207. External air source is filtered by the air intake mechanism 5 and enters the air duct 3. After being cooled by heat exchange with the underground soil, it is transported to the hollow plate 6 by the fan 1210 and evenly sprayed out through the air holes 7 to uniformly cool the inside of the box 1. The liquid cooling and air cooling dual circulation can operate simultaneously, quickly stabilizing the battery temperature in the optimal operating range and avoiding the problems of local overheating and excessive temperature rise. At the same time, there is no need to increase the operating power of the fan 1210 and the water pump 1203, which greatly reduces the system energy consumption.

[0093] When the equipment is operating under suitable ambient temperature conditions in spring and autumn, the servo motor 1214 drives the baffle 1216 to open the through slot 1209 of the middle partition 1208 and close the through slot 1209 of the lower partition 1207. The air-cooling system directly draws external ambient air for heat dissipation, without the need for heat exchange through the air duct 3, reducing wind resistance and further reducing the operating energy consumption of the fan 1210. The liquid cooling system can be started and stopped according to the heat generation of the battery to achieve optimal energy consumption control.

[0094] When the equipment operates in low-temperature conditions during winter, it utilizes the geothermal characteristics of the underground constant temperature layer to heat the coolant and air source through the water-cooled radiator 8 and the air duct 3, respectively. Then, the heat is transferred to the inside of the housing 1 through liquid cooling and air cooling circulation, providing a suitable operating temperature for the battery. This avoids the problem of decreased battery charging and discharging efficiency and capacity decay caused by low-temperature environment, ensuring the battery's energy storage capacity and service life in low-temperature environment. There is no need to install an additional electric heating device, further reducing the energy consumption of the equipment.

[0095] During the equipment maintenance and relocation phase, starting the lifting motor 404 in reverse will drive the buried heat exchange components upward and retract them into the groove 102, restoring the standard container structure. This facilitates the transfer, maintenance, and relocation of the equipment, and it can be reused to adapt to different application scenarios.

[0096] The above description is merely a further embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present invention, shall fall within the scope of protection of the present invention.
