Application of thermal gel in battery thermal management

At present, most pure electric vehicles are composed of multiple batteries in a battery pack. When the car is running, the battery pack will emit heat while discharging. At this time, the heat needs to be taken out of the battery pack in time, and the heat is taken out through the external heat dissipation system In the car, the battery pack is composed of multiple batteries. There are irregular gaps between the battery and the battery. The air is a poor conductor of heat, which will hinder the flow of heat in the battery pack, so that the battery pack is locally hot, and the heat cannot be dissipated. .

The common thermal conductive materials on the market are thermally conductive pads based on thermally conductive silicone sheets, but thermally conductive pads cannot effectively fill the gaps between the interfaces, and thermally conductive gels can be used here.

Thermal gel is a kind of gel that uses silicone resin as the matrix, adds thermally conductive fillers and bonding materials in a certain proportion, and is processed through a special process. In the industry, it is also called thermal gel mud and thermally conductive mud. It has high thermal conductivity, low thermal resistance and good thixotropy. It has become an ideal material for applications with large gap tolerances. It is filled between the electronic components that need to be cooled and the radiator/shell to make close contact and reduce Thermal resistance quickly and effectively reduces the temperature of electronic components, thereby prolonging the service life of electronic components and improving their reliability.
