Battery heat dissipation device for new energy automobile

Abstract

The invention discloses a battery heat dissipation device for a new energy automobile in the field of new energy automobile batteries. The battery heat dissipation device comprises a battery box and acooling unit fixed on the outer wall of the battery box; the battery box comprises a heat dissipation body, a vertical heat dissipation channel and a heat dissipation base; the cooling unit comprisesa booster pump and a liquid storage tank for storing cooling liquid; the periphery of the heat dissipation body vertically extends downwards to form an open thin wall; grooves with wavy edges are formed in the bottom surface of the heat dissipation body and the surface of the heat dissipation base; a liquid inlet is formed in the rear surface of the heat dissipation body; and a liquid outlet is formed in the front surface of the heat dissipation base. According to the battery heat dissipation device capable of efficiently dissipating heat, the power performance, reliability and safety of thebattery are improved, and the service life of the battery is prolonged.

Description

technical field [0001] The invention relates to the field of new energy vehicle batteries, in particular to a battery cooling device for new energy vehicles. Background technique [0002] New energy vehicles refer to all other energy vehicles except gasoline and diesel engines, including fuel cell vehicles, hybrid vehicles, hydrogen energy vehicles and solar vehicles. At present, most of the new energy vehicles sold in the Chinese market are hybrid vehicles and pure electric vehicles. A pure electric vehicle is a vehicle that uses a single battery as the energy storage power source. Provide electric energy to drive the motor to run, thereby driving the car. During the working process, a large amount of heat will be generated. If the heat is not transferred to the outside in time, the working efficiency and working life of the battery will be reduced, and even the battery will be burned. Contents of the invention [0003] Technical issues resolved [0004] Aiming at the p...
