Heat dissipation structure of a battery pack

Abstract

The invention discloses a heat dissipation structure of a battery pack, which belongs to the technical field of batteries, and comprises a heat dissipation box, a heat dissipation cover body, a heat dissipation cover body two, a battery installation grid and a cold air assembly, the heat dissipation cover body one, the heat dissipation cover body two They are respectively arranged at both ends of the box body. The battery installation grid and the cooling air assembly are respectively arranged in the heat dissipation box. between; the heat dissipation box is provided with a heat-absorbing cavity, and the heat-absorbing cavity is filled with heat-conducting silicone grease; the heat dissipation cover one is provided with several heat dissipation outlets, and the heat dissipation cover two is provided with Several cold air inlets. The invention can effectively reduce the temperature of the battery pack, and has good heat dissipation effect; it is designed from the whole of the battery pack itself, has simple structure, small volume structure, small weight gain and convenient use of the battery pack.

Description

technical field [0001] The invention relates to a heat dissipation structure of a battery pack, which belongs to the technical field of batteries. Background technique [0002] The battery pack is composed of a number of closely fitted battery cells so that there is no gap between each battery cell, but it is easy to cause the temperature inside the battery pack to be too high, which will cause the battery to heat up, damage the core body, and even cause a fire. explode. There are many ways of heat dissipation, such as natural cooling, air cooling, circulating liquid cooling, etc., but the heat dissipation effect of natural cooling, air cooling, and circulating liquid cooling is poor, and the existing air cooling and circulating liquid cooling greatly increase the battery The weight and volume are not conducive to the use of battery packs. Contents of the invention [0003] Aiming at the problems existing in the above-mentioned prior art, the present invention provides a...

[0002] The battery pack is composed of a number of closely fitted battery cells so that there is no gap between each battery cell, but it is easy to cause the temperature inside the battery pack to be too high, which will cause the battery to heat up, damage the core, and even cause a fire. explode

There are many ways to dissipate heat, such as natural cooling, air cooling, and circulating liquid cooling, but natural cooling, air cooling, and circulating liquid cooling have poor heat dissipation effects, and the existing air cooling and circulating liquid cooling greatly increase the battery capacity Weight and bulk, not conducive to the use of battery packs
