‌ The application of heat sink in the energy storage system is mainly to improve the heat dissipation efficiency of the system by forced convection. ‌ For example, in an energy storage battery pack, a large amount of heat is generated when the battery is working, and it needs to be dissipated through a radiator to keep the temperature of the battery pack within a controllable range. In addition, on the controller, converter and other equipment in the energy storage device, the radiator can also reduce the heat generated when the electrical components work, and improve the stability and life of the system.
