Abstract

The invention discloses a cooling device for an electric vehicle battery, which belongs to the technical field of new energy vehicle batteries. A heat dissipation device for an electric vehicle battery, comprising a box body with serpentine grooves on the bottom inner wall, cooling pipes in the serpentine grooves, a fixing seat connected to the bottom inner wall of the box body, and four The fixed groove, the horizontal inner wall of the box body is connected with the heat dissipation plate and the heat conduction plate in sequence in the horizontal direction, the heat conduction plate is fixedly connected with the longitudinal outer wall of the fixing seat, and the electric telescopic rod and the evenly distributed heat dissipation are connected between the heat dissipation plate and the heat conduction plate Assemblies, a damping assembly is connected between the heat dissipation plate and the inner wall of the box; the invention has a reasonable structure, and adopts a combination of water cooling and air cooling to improve heat dissipation efficiency, and at the same time realizes the adjustable performance of air cooling and heat dissipation, which is convenient for rapid cooling.

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,...
