[0029] See Figure 1-5 As shown, an energy storage power station includes a station building 10 arranged above ground, with energy storage battery packs 11 arranged in the station building 10, and air distribution ducts 12 arranged in the station building 10.

The specific configuration is based on the needs of the user. The air distribution ducts 12 are arranged in the station building 10 to distribute air to the station building 10 to regulate the air flow and temperature within the station building 10.

[0030] The present application also includes an air supply system for supplying air to the air distribution duct 12, and the air supply system includes an air inlet duct 13, a heat exchange duct 14, an air outlet duct 15, and a fan 16; one end of the air inlet duct 13 is above the ground, for introducing external air into the air inlet duct 13, and the other end of the air inlet duct 13 is connected with the heat exchange duct 14, that is, the air in the air inlet duct 13 can enter the heat exchange duct 14; the heat exchange duct 14 is below the ground, for exchanging heat between the air passing through it and the material below the ground; the material for underground heat exchange can be underground soil or groundwater, and the underground material is heat exchanged with the air in the pipe through the heat exchange duct 14 to change the temperature of the air. For example, in summer, the underground temperature is lower than the ground temperature. Degree, so that the temperature of the air drops after heat exchange. In winter, the underground temperature is higher than the ground temperature. The temperature of the air rises after heat exchange, so as to exchange heat between the underground temperature and the air; one end of the outlet duct 15 is connected with the heat exchange duct 14, that is, the heat-exchanged air in the heat exchange duct 14 can enter the outlet duct 15, and the other end of the outlet duct 15 is connected to the air inlet of the fan 16, and the air outlet of the fan 16 is connected with the air distribution duct 12. The heat-exchanged air is sent into the air distribution duct 12 in the station building 10 through the transportation of the fan 16, and then the temperature in the station building 10 is adjusted to increase the stability of the air temperature in the station building 10, and also to provide the energy storage battery pack 11 with a proper storage temperature guarantee.

[0031] The heat exchange circuit 14 includes an air distributor 17, an air collector 18, and at least one heat exchanger assembly 19. The heat exchanger assembly 19 is connected between the air distributor 17 and the air collector 18. The air distributor 17 is connected to the air inlet pipe 13, and the air distributor 17 is connected to the air outlet pipe 15. The air in the air inlet pipe 13 is sent to the heat exchange assembly through the air distributor 17, and then collected by the air collector 18 and sent to the air outlet pipe 15.

[0032] In some implementations, the air distributor 17 and the air collector 18 are pipes arranged horizontally below ground level. The heat exchanger assembly 19 includes a heat exchange pipe 20, which communicates between the air distributor 17 and the air collector 18. A plurality of radiating metal sheets 21 are fixedly arranged along the periphery of the heat exchange pipe 20 along its length. The radiating metal sheets 21 are evenly spaced along the periphery of the heat exchange pipe 20. The radiating metal sheets 21 increase the heat exchange connection between the heat exchange pipe 20 and the underground, thereby enhancing the heat exchange capacity between the heat exchange pipe 20 and the air within it.

[0033] In some implementations, an air distribution plate 22 is fixedly provided at the upper part of the air distributor 17 along its length direction. The air distribution plate 22 divides the interior of the air distributor 17 into upper and lower chambers. The upper chamber is connected to the air inlet pipe 13, and the lower chamber is connected to the heat exchange pipe 20. Air distribution holes are distributed on the air distribution plate 22. The air in the upper and lower chambers is circulated through the air distribution holes 23. In this way, the air is distributed as evenly as possible in the air distributor 17, and a certain slow flow of the air can also be formed.

[0034] In some implementations, the heat exchange pipe 20 is formed by connecting multiple sections of curved pipes and / or straight pipes. When using curved pipes, the length of the underground curved pipes can be increased compared to using straight pipes of the same length to obtain a better heat exchange area.

[0035] In some implementations, adjacent radiating metal sheets 21 are fixedly connected using at least one fixing rod 24. Specifically, a through hole 25 can be provided on the outer edge of the radiating metal sheet 21 for the fixing rod 24 to pass through. The fixing rod and the radiating metal sheet 21 can be connected using conventional fixing methods such as welding. This enhances the overall connection strength between the radiating metal sheets 21 and improves the deformation resistance of the radiating metal sheets 21 when underground.

[0036] In some embodiments, an extension sleeve 26 extending outward is provided in the middle portion of the radiation metal sheet 21. The extension sleeve 26 is sleeved on the heat exchange pipe 20. An assembly gap is formed between the inner wall of the extension sleeve 26 and the outer wall of the heat exchange pipe 20. The radiation metal sheet 21 is installed on the heat exchange pipe 20. The inner wall of the extension sleeve 26 fits with the outer wall of the heat exchange pipe to increase the contact area and expand the radiation capacity; an insertion portion 27 is formed on the outer peripheral wall of the extension sleeve 26 on one side, and an insertion groove 28 is formed on the inner peripheral wall of the extension sleeve 26 on the other side to enhance the assembly stability between adjacent radiation metal sheets 21.

[0037] In some implementations, the internal cross-sections of the air distributor 17 and the air collector 18 are larger than the cross-section of the heat exchange pipe 20 .

[0038] In some embodiments, the connection point between the air inlet duct 13 and the air distributor 17 is staggered with the connection point between the heat exchange pipe 20 and the air distributor 17 to avoid air directly entering a certain heat exchange pipe 20, so that the air enters each heat exchange pipe 20 as balanced as possible.

[0039] In some implementations, the radiation metal sheet 21 is coated with a graphene layer to further enhance the radiation capability of the radiation metal sheet 21 .

[0040] In some embodiments, a filter box 29 having an air inlet and an air outlet is further included. An air filter element assembly is mounted within the filter box 29 and positioned between the air inlet and the air outlet. An air inlet hood 30 is mounted above the filter box 29 and communicates with the air inlet. The air inlet hood has air openings on its periphery for admitting external air, and the air outlet communicates with the air inlet duct 13. The air filter element assembly can filter the air, and the air filter element assembly in the filter box can be replaced regularly to ensure effective filtering.

[0041] In some implementations, a drying box 31 is arranged between the air outlet duct 15 and the fan 16 to dry the air in the air outlet duct 15 before entering the fan 16. The drying box 31 is provided with an air desiccant to dry the air discharged from the air outlet duct 15 to improve the dryness of the air entering the station building 10.

[0042] In some embodiments, a water collector 32 is disposed below the wind collector 18 and is positioned lower than the wind collector 18. One end of the wind collector 18 is higher than the other end, and the lower end of the wind collector 18 is connected to the water collector 32. In this way, water generated in the wind collector 18 flows into the water collector 32 for centralized collection. The water collector 32 can be tubular or rectangular, as long as it is positioned lower than the wind collector 18 so that the water generated in the wind collector 18 can flow into the water collector 32. A water pump 33 is disposed above the ground and is connected to the water collector 32 via a pipe. A liquid level sensor is disposed in the water collector 32. When the liquid level sensor detects that the water level has reached a set value, the water pump 33 starts pumping water to prevent excessive water from accumulating in the water collector 32.

[0043] In some implementations, the air distribution duct 12 in the station building 10 can be arranged along the bottom, middle, and top of the inner wall of the station building 10. The air distribution duct 12 is a pipe with air holes opened on the pipe to arrange the wind.

[0044] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention.
