Abstract

The embodiment of the utility model discloses a liquid cooling unit for heat dissipation of a battery and an energy storage box, a controller, a driver and a turbulent flow fan are sealed in an electric control box, the mode that the controller and the turbulent flow fan are arranged in the electric control box in a staggered mode in the height direction is adopted, air flow circulation flow is formed in the electric control box, the temperature in the electric control box is kept uniform, and the heat dissipation efficiency of the battery is improved. And over-temperature work of the controller is avoided. Moreover, the air duct is arranged outside the electric control box, and the second radiator is arranged in the air duct, so that most of heat can be taken away in cooperation with the air draft effect of the heat dissipation fan located at the top and the heat dissipation effect of the first radiator, and heat dissipation of the electric power system is guaranteed.
