Case application of thermal interface materials in household appliances

TVs, refrigerators, electric fans, electric light tubes, computers, routers and other household appliances are often used in our daily life, and most of the electrical equipment is limited in size, so it is not possible to install external radiators for cooling, 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 radiator and the heat source.

Thermal interface material is a heat dissipation auxiliary material to deal with the heat conduction problem of equipment. There are many types of thermal interface materials, such as silicon-free thermal pads, carbon fiber thermal pads, thermal phase change sheets, thermal silicone cloth, thermal grease, thermal Gel, heat-conducting silicone sheet, heat-conducting and wave-absorbing materials, etc., the function of the heat-conducting interface material is to fill the gap between the heat sink and the heat source of the equipment, remove the air in the gap, and reduce the contact thermal resistance between the two, thereby increasing the heat in the The transfer rate between the two improves the cooling effect.

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