Application of thermal interface material in household appliances

Televisions, refrigerators, electric fans, lamps, computers, routers and other household appliances are often used in our lives, and most of the electrical equipment is limited in size and cannot be specially installed with external radiators to cool down, so household appliances Most of the heat dissipation system is installed above the heat source of the electrical appliance, and the excess heat is guided to the heat dissipation module through the contact between the heat sink and the heat source.


Thermal interface material is a heat dissipation auxiliary material to deal with the problem of thermal conduction of equipment. There are many types of thermal interface materials, such as silicon-free thermal pads, carbon fiber thermal pads, thermal phase change sheets, thermally conductive silicone sheet, thermally conductive silicone grease, thermally conductive Gel, thermally conductive silica gel sheet, thermally conductive wave absorbing material, etc. The role of thermally conductive interface material is to fill the gap between the radiator and the heating source of the device, remove the air in the gap, reduce the contact thermal resistance between the two, and thus improve the heat dissipation. The transfer rate between the two improves the heat dissipation effect.

Although there are many types of thermal interface materials, they are not universal in all occasions. Each thermal interface material has its own unique selling point and has different effects in different occasions. Customers need to choose according to the characteristics of the occasion.
