Heat dissipation device for new energy automobile battery

Abstract

The invention discloses a heat dissipation device for a new energy automobile battery. The invention belongs to the technical field of new-energy vehicles. The device comprises an installation net box, a box cover, a first heat dissipation assembly, a second heat dissipation assembly, a wiping assembly, a ventilation heat dissipation assembly, a ventilation assembly and a drainage assembly. The box cover is arranged at the top of the installation net box. The first heat dissipation assembly is arranged at the bottom of the installation net box. The second heat dissipation assembly is arrangedon the side wall of the installation net box and is in sliding fit with the side wall of the installation net box. The wiping assembly is arranged in the installation net box. The ventilation heat dissipation assembly is arranged on the side wall of the installation net box. The ventilation assembly is arranged on the side wall, symmetrical to the ventilation heat dissipation assembly, of the installation net box. The drainage assembly is arranged at the bottom of the installation net box. A plurality of semiconductor chilling plates work on an installation net plate to generate cold air, andthree first heat dissipation fans work to convey the cold air to the bottom of the battery to conduct heat dissipation operation on the battery.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a heat dissipation device for batteries of new energy vehicles. Background technique [0002] With the continuous depletion of fossil energy in modern society, the energy structure of people's lives is also constantly changing, such as cars, many cars have given up the traditional pure fossil energy supply, and instead use a variety of energy sources to make travel more environmentally friendly, such as New energy vehicles, they use more electricity, reduce greenhouse gas emissions during the driving process, and effectively protect the environment, but the batteries of this type of vehicle will continue to accumulate heat during the driving process, which will affect the efficiency and safety. . [0003] For example, the patent with the publication number CN108682766B relates to a heat sink for a new energy vehicle battery, including a bottom plate, a heat dissipati...
