[0002] The heat transfer method in which two or three basic heat transfer methods work at the same time is called composite heat exchange. The heat obtained by composite heat exchange needs to be stored in a specific device for easy use; with the capacity and use of the energy storage battery system As the power gradually increases, its heat production also increases, resulting in a large temperature rise and high temperature of the energy storage battery system during the working process; because the comprehensive performance of the lithium-ion battery is sensitive to the working temperature, the battery works at high temperature for a long time , it will reduce its power performance, accelerate battery aging, and affect the cycle life of the energy storage system; therefore, it is necessary to set up a specific cooling device to cool and cool it

[0003] Most of the existing cooling devices are equipped with a liquid cooling device. The liquid cooling device is generally fixed on the outer wall of the energy storage box. Through the setting of circulating water in the liquid cooling device, heat exchange treatment is performed with the heat of the energy storage box, thereby Realize the cooling treatment of the energy storage box; but the fixed liquid cooling device can only exchange heat and cool down the fixed position of the energy storage box, and the heat in other positions in the energy storage box needs to be transferred to the location of the liquid cooling device to realize heat exchange , this will lead to poor heat dissipation and cooling effect on the energy storage box, and then the problem of component damage caused by excessive heat in the energy storage box
