The invention discloses a battery cooling device of an electric vehicle. The battery cooling device comprises a battery box body, wherein a cooling liquid box is fixedly connected to a lower part of the battery box body, a battery box cover is arranged at the top of the battery box body, a return pipe and a transmission pipe are arranged on the battery box body and communicate with the cooling liquid box, a battery cavity is formed in the battery box body, cooling coils are arranged in the battery box body and encircle an outer wall of the battery cavity, heat absorption fins are arranged on a surface of an inner wall of the battery cavity, and a rubber cushion is pasted at one end of each heat absorption fin by an adhesive. The battery box body is matched with the cooling liquid box, heat dissipated from a battery can be rapidly absorbed by a circulated cooling liquid, so that the purpose of rapidly reducing temperature is achieved; and moreover, the heat absorption fins made of aluminum alloy materials are arranged on the inner wall of the battery cavity, the heat dissipated from the battery can be rapidly absorbed, the heat of the heat absorption fins is absorbed by the cooling coils to achieve temperature reduction, and the heat exchange efficiency is improved.
Description
technical field [0001] The invention relates to the field of auto parts, in particular to a battery cooling device for an electric vehicle. Background technique [0002] An electric vehicle (BEV) refers to a vehicle that is powered by a vehicle-mounted power supply, drives the wheels with a motor, and meets the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic, but the current technology is still immature. [0003] The battery casing in the existing electric vehicles is made of ordinary materials, which has poor ventilation and heat dissipation, and unreasonable structural design, which cannot quickly discharge the heat emitted by the battery, resulting in local high temperature and affecting the service life of the battery. Therefore, we propose an electric The battery cooling device of the car solves the above existing problems. Contents of the invention [0004] ...
