Silicone thermal pads in battery application solutions

The battery use process is the process of discharging. The battery releases current to drive the equipment. During this process, the battery generates heat. The higher the power, the more heat it releases. The advancement of technology and the requirements for production capacity, the battery trend Due to the development of miniaturization and high savings, although some large-scale battery packs are large in size, their internal space utilization is very high, resulting in a small internal space, and heat is not easy to circulate after generation, resulting in local high temperatures.

High temperature is one of the important factors that affect battery life, performance, and safety. Timely heat dissipation is indispensable. There are gaps between the battery and the case. The air between the gaps will hinder the flow of heat, making it difficult to dissipate heat to the outside. Therefore, it is necessary to use thermally conductive materials to fill the gaps, eliminate the air in the gaps, reduce contact thermal resistance, and improve thermal conductivity. Silicone thermally conductive gaskets are a soft, thermally conductive gap filling material, which is well-applied in the battery field. , Then what is the silicone thermal pad?

Silicone thermal pad is a kind of gap-filling thermally conductive gasket made of silicone resin as the base material and added with temperature-resistant and thermally conductive materials. It has the characteristics of high thermal conductivity, low thermal resistance, insulation, compressibility, etc., because of its The softer hardness makes it possible to realize a smaller thermal resistance under low pressure conditions, and at the same time eliminate the air between the contact surfaces and fully fill the rough surfaces between the contact surfaces to improve the heat conduction effect of the contact surfaces. Because of the good filling effect of the silica gel thermal pad, it can effectively conduct the heat of the heat source to the shell, and the silica gel thermal pad has good compressibility and elasticity, and can serve as a shock-absorbing pad.
