What is the working principle of thermal conductive silicone pad and silicone heat sink?

         Thermally conductive silicone pad is also called thermally conductive silicone sheet, silicone heat sink, soft thermally conductive pad, and Taiwan is also called thermally conductive silicone film, etc. It is actually a product, the main ingredient is silica gel as the base material, and metal is added. Various auxiliary materials such as oxides are a kind of heat conductive medium material synthesized through a special process. It is specially produced for the design of using the gap to transfer heat. It can fill the gap and complete the heat transfer between the heating part and the heat dissipation part. Insulation, shock absorption, sealing, etc., can meet the design requirements of equipment miniaturization and ultra-thinness. It is extremely manufacturable and usable, and has a wide range of thicknesses. It is an excellent thermally conductive filling material.

          What is the working principle of thermally conductive silicone sheet?Let me introduce for you.

          The effect of thermal interface material on heat conduction is mainly reflected in the following aspects: 

          A. There is no thermal interface material between the heating chip and the heat sink, and the heat flow path through the two connecting surfaces. The heat resistance of air is enlarged, and the heat conduction effect is poor. 

          B. When there is a good thermal interface material between the heating chip and the heat sink or the casing, the path of the heat flow through the two connecting surfaces. The thermally conductive silicone sheet fills the air space. Since the heat transfer efficiency of the thermally conductive silicone sheet is dozens of times that of air, it improves the overall thermal conductivity and makes heat dissipation smoother. In layman's terms, the working principle of thermal conductive silicone pad is mainly to connect two substances to conduct heat and heat dissipation and insulation. The thermal conductivity is different, and the thermal conductivity is different. Everyone is buying thermal conductive silicone pads, and silicone heat sinks can be understood first. How it works.
