Abstract

The invention discloses an electric vehicle battery heat dissipation device, and belongs to the technical field of new energy vehicle battery. The electric vehicle battery heat dissipation device includes a box body; a snake-shaped groove is arranged on the inner wall of the bottom of the box body, a cooling pipe is arranged in the snake-shaped groove, a fixed seat is connected with the inner wallof the bottom of the box body, and four fixed grooves are formed in the bottom of the fixed seat; a heat dissipation plate and a heat conduction plate are connected in turn on the transverse inner side wall of the box body along the horizontal direction; the heat conduction plate is fixedly connected with the longitudinal outer side wall of the fixed seat; an electric telescopic rod and a uniformly distributed heat dissipation assembly are connected between the heat dissipation plate and the heat conduction plate, and shock absorbing assembly is connected between the heat dissipation plate and the inner wall of the box body. The structure is reasonable, and the heat dissipation efficiency is improved by combining water cooling with air cooling, and the air cooling and heat dissipation adjustable performance is realized at the same time, and rapid cooling is facilitated.

Description

technical field [0001] The invention relates to the technical field of new energy automobile batteries, in particular to a heat dissipation device for electric automobile batteries. Background technique [0002] The energy storage of new energy vehicles requires the use of high-performance power batteries. During use, the internal temperature of the battery will rise due to high-current charging and discharging, causing the battery temperature to exceed its normal operating temperature, and even cause the battery to rupture, leak, Fire and explosion will affect the reliability and safety of the battery, so it is particularly important to efficiently dissipate heat for the battery pack of new energy vehicles. Contents of the invention [0003] The purpose of the present invention is to solve the problem of poor rapid heat dissipation performance in the prior art, and propose an electric vehicle battery heat dissipation device. [0004] In order to achieve the above object,...
