[0002] An energy storage integrated machine is a comprehensive energy storage system integrating an energy storage device and an inverter. It mainly consists of components such as a battery pack, a battery management system, an inverter, and an energy management system. The energy storage integrated machine can convert electric energy from the power grid or renewable energy power generation equipment into direct current for storage, and then convert the stored electric energy into alternating current for users when needed. This comprehensive energy storage solution can be used for functions such as balancing the power grid load, regulating the power supply and demand, and providing emergency backup power.

[0003] Most of the existing energy storage integrated machines mainly use air cooling for heat dissipation. However, for outdoor use, air cooling is affected by the ambient temperature and air volume flow, resulting in a large temperature difference between energy storage systems, which in turn leads to inconsistent attenuation of battery cells, thus affecting the lifespan of the battery cells. Therefore, there are still some deficiencies.

[0022] Refer to the appendix Figures 1-4, the array liquid-cooled energy storage integrated cabinet provided by the present utility model includes a cabinet body 100 and energy storage battery cells. The inner wall of the cabinet body 100 is separated by a plurality of partitions 120 to form a placement cavity 110 for storing the energy storage battery cells. A heat dissipation component for dissipating heat from the energy storage battery cells is further provided on the cabinet body 100.

Adjacent two lower liquid storage tanks 220 are communicated through a connecting pipe. Specifically, the low-temperature water cooled by the cold water equipment can enter the upper liquid storage tank 200 through the water supply pipe 210 and the short pipes for storage. The upper liquid storage tank 200 will convey the low-temperature water to the support frame 300 through a water inlet pipe, so that the low-temperature water can flow in the placement cavity 110. When the low-temperature water flows, it will reduce the temperature in the placement cavity 110, and cooperate with the air cooling component to cool the energy storage battery cells. The cooled water after use will flow back and gather in the lower liquid storage tank 220, and flow back to the cold water equipment through the return water pipe 221 for cooling and reuse. The cold water between adjacent lower liquid storage tanks 220 is discharged through the connecting pipe;

[0023] A plurality of support frames 300 are both arranged on the inner walls on both sides of the placement cavity 110. Bar-shaped tubes 310 are fixedly connected to the front and rear sides of the inner walls of the support frames 300.

The bottoms of the inner walls of the bottom bar-shaped tubes 310 are all connected to the upper part of one side of the inner wall of the lower liquid storage tank 220 through drain pipes. On the outer walls of the opposite sides of the two support frames 300 arranged in each placement cavity 110 and at positions corresponding to the energy storage battery cells, support blocks 320 are fixed. Placement sinks are provided at the tops of the outer walls of the support blocks 320. The two sides of the bottom ends of the outer walls of the energy storage battery cells are both abutted against the inner walls of the placement sinks. Specifically, the outer walls of the provided support frames 300 can support the placed energy storage battery cells through the fixed support blocks 320. The cooling water in the upper liquid storage tank 200 can enter the top bar-shaped tubes 310 through the water inlet pipes, and the flowing water will flow in the bar-shaped tubes 310 and the shunt tubes 311. The materials of the bar-shaped tubes 310 and the shunt tubes 311 can be selected as copper, aluminum, etc. It can release the cold air of the low-temperature water into the placement cavity 110, and the low-temperature water in the bottom bar-shaped tubes 310 will flow back to the lower liquid storage tank 220 through the drain pipes and be discharged;

[0024] The air-cooling component is arranged at the upper end of the inner wall of the cabinet body 100 and below the upper liquid storage tank 200. The air outlet end of the air-cooling component is arranged on one side of the inner wall of the placement cavity 110. The air-cooling component includes a cold air blower 400. The cold air blower 400 is fixed on the upper part of one side of the outer wall of the cabinet body 100. The air outlet end of the cold air blower 400 is fixedly connected to a main air supply pipe 410. The main air supply pipe 410 is installed at the top of the inner wall of the cabinet body 100 and below the upper liquid storage tank 200. At the bottom ends of the inner walls of the cold air blower 400 and at positions corresponding to the partition plate 120, air supply branch pipes 420 are fixedly connected. The ends of the air supply branch pipes 420 far from the main air supply pipe 410 are all embedded in the inside of the partition plate 120. Air outlet nozzles 421 are fixedly connected to the outer walls of the air supply branch pipes 420 and on the right sides of the energy storage battery cells. Exhaust fans 130 are installed at the rear ends of the inner walls of the placement cavity 110 and on the left sides of the energy storage battery cells. Specifically, after the provided cold air blower 400 is started, the refrigerated cold air can be conveyed to the air supply branch pipes 420 through the main air supply pipe 410, so that the air supply branch pipes 420 can blow the cold air from the direction of the energy storage battery cells through the air outlet nozzles 421. When the cold air is blown out, it will also blow the cold generated by the low-temperature water flowing in the shunt tubes 311 towards the direction of the energy storage battery cells, so that the temperature of the energy storage battery cells can be reduced. At the same time, the exhaust fans 130 are started to discharge the air in the placement cavity 110 from the rear side, so as to accelerate the air flow in the placement cavity 110, thereby achieving a certain cooling purpose.

The upper liquid storage tank 200 will transport the low-temperature water to the top strip pipe 310 through the water inlet pipe. The flowing water will flow in the strip pipe 310 and the shunt pipe 311, enabling the low-temperature water to flow in the placement cavity 110. When the low-temperature water flows, it will reduce the temperature in the placement cavity 110. At the same time, after the cold air blower 400 is started, the refrigerated cold air can be transported to the air supply branch pipe 420 through the air supply main pipe 410, so that the air supply branch pipe 420 can blow the cold air from the direction of the energy storage battery core through the air outlet nozzle 421. When the cold air is blown out, it will also blow the cold generated by the low-temperature water flowing in the shunt pipe 311 towards the energy storage battery core, enabling the temperature of the energy storage battery core to be reduced. At the same time, the exhaust fan 130 is started to discharge the air in the placement cavity 110 from the rear side, thereby accelerating the air flow in the placement cavity 110. The cooled water after use will flow back and gather in the lower liquid storage tank 220, and flow back to the cold water equipment through the water return pipe 221 for cooling and reuse. The cold water between adjacent lower liquid storage tanks 220 is discharged through the connecting pipe.
