New energy vehicle plate type battery cooling structure

Abstract

The utility model discloses a new energy car board type battery cooling structure, including the battery body, the battery body upper surface is fixed with the heat conduction metal sheet, and the heat conduction metal sheet upper surface is fixed with a plurality of interval arrangement's radiating fin, and the heat conduction metal sheet bottom surface and the battery body contact surface lay the graphene heat conduction film, the battery body lower surface is fixed with the liquid cooling board, and the liquid cooling board is connected cooling liquid circulating mechanism, the radiating fin inside is equipped with the heat pipe, and the condensing end of heat pipe extends to the cooling liquid tank inner chamber, and the utility model discloses compared with prior art advantage lies in: radiating fin and heat pipe combine, utilize the efficient heat conduction characteristic of heat pipe, and the heat that radiating fin absorbs is rapidly transferred to the cooling liquid tank. Evaporation section is embedded in the radiating fin, and the condensing section is equipped with spiral heat exchange part and goes into the cooling liquid tank, and the heat exchange area is increased, and the heat dissipation effect is strengthened, and heat pipe radiating and liquid cooling board cooling combine, improve the cooling effect, and can cool down fast, solve the response lag problem.
