Abstract

The invention belongs to the technical field of automobile batteries. The invention discloses an electric automobile battery pack with good heat dissipation performance. The battery pack comprises anouter box, a box cover, a heat dissipation inner box and a battery pack, a hinge shaft is mounted at one end of the outer box; the box cover is hinged with the outer box through the hinge shaft; the other end of the box cover is clamped with the outer box; a heat dissipation inner box is mounted in the outer box, a plurality of buffer spring columns are mounted at the bottom in the heat dissipation inner box, a mounting base is fixedly connected to the tops of the buffer spring columns, a battery pack is mounted on the mounting base, and a refrigeration water cavity, a first circulating pump and a second circulating pump are mounted in a bottom plate of the outer box. According to the invention, the outer box and the box cover are clamped and connected in a running fit manner; the mountingbase and the buffer spring columns are arranged at the inner bottom of the heat dissipation inner box, damage caused by shaking is avoided, a refrigeration piece in an inner cavity of a refrigerationwater cavity cools circulating water, the circulating water is conveyed to the inner cavity of the heat dissipation water cavity through a first circulating pump and a second circulating pump, and the heat dissipation effect is better.

Description

technical field [0001] The invention relates to the technical field of automobile batteries, in particular to an electric automobile battery pack with good heat dissipation performance. Background technique [0002] The use of fossil energy has caused the earth's ecological environment to become worse and worse. While restricting the use of fossil energy, people are also constantly developing new energy. As a clean energy, electric energy is becoming more and more popular. With the continuous increase of power equipment, batteries have become a must for many equipment. [0003] The battery often generates heat during use. If the heat cannot be dissipated in time, the temperature of the battery will rise, which will cause problems such as reduced battery efficiency and practical life, and may even cause damage to the battery or other equipment due to the high temperature of the battery; [0004] A power vehicle battery pack refers to a car battery pack with a capacity of mor...
