Why use thermal interface materials?

Air is a poor conductor of heat, and the heat conduction in the air is very poor. In addition, the space inside the equipment is limited and there is no ventilation, so the heat is easy to accumulate in the equipment and the local temperature of the equipment rises. Install a heatsink to reduce the temperature inside the device by actively directing heat to the outside.

In addition, the use of the radiator and the use of thermal interface materials filling the gap between heat source and heat sink, plane and plane between the aperture, even if he seems to have a joint, but the actual contact area is not much, heat transfer between the two transmission rate will be affected by the resistance and collocation, so the effect of thermal interface materials can fill the gap between, Reduce the contact thermal resistance between the heat source and the radiator, so as to increase the heat transfer rate between the two, improve the heat dissipation effect.

Whether it is a radiator or a heat sink, they need to be used to fit the heat source surface, so they need to use thermal interface materials, thermal interface materials are excellent heat dissipation auxiliary materials to deal with the heat conduction problems of equipment, in electronic equipment, large machinery and equipment, transportation has its application.
