Various electronic products and machinery have become indispensable in people's lives and work, just like the mobile phones, computers, pure electric vehicles, elevators, and subways that we often use as driving energy. Electrical appliances generate heat during use, so it is necessary to do a good job of heat dissipation.
If only relying on the heat source to dissipate heat autonomously, it is impossible to reduce the temperature of the heat source, because the heat transfer efficiency in the air is full, and the internal environment of the electrical appliance is not easy to circulate heat, so it is necessary to use a heat sink to actively guide the heat into the heat sink, thereby reducing the temperature of the electrical appliance.
There is a gap between the heat source and the radiator, and even if pressure is applied, the gap cannot be eliminated. Therefore, when heat is transferred between the two, the thermal conductivity efficiency will decrease, and the heat dissipation effect cannot meet the requirements. Therefore, thermal conductive joint filling materials are used.
Thermal conductive caulking material is a new type of material specially used to solve the problem of heat conduction of equipment. There are many kinds of thermal conductive silicone gasket, thermal conductive gel, thermal conductive silicone tape, thermal conductive silicone grease, thermal conductive phase change sheet, silicon free thermal conductive gasket, carbon fiber thermal conductive gasket, which are widely used in the market.
The main function of thermal conductive joint filling material is to fill the gap between the heat source and the radiator, eliminate the air in the gap and fill the gap, reduce the contact thermal resistance between the two, so that heat can be quickly transferred from the thermal conductive joint filling material to the radiator, and then carried away by the radiator, thereby improving the thermal conductivity of the electrical appliance and ensuring its performance and service life.
