What is thermally conductive gap filler?

When the current passes through the electrical components, heat will be generated, which is an unavoidable and normal phenomenon. The common heat dissipation method is to install a heat sink on the heat source, and guide the heat from the surface of the heat source to the heat sink, but the heat dissipation effect will reach less than expected.

The way of heat transmission is mainly heat conduction, heat radiation and heat convection. The heat conduction speed in the air is lower than the contact between solids. There is a gap between the heat source and the radiator. The air in the gap will reduce the heat transfer efficiency, thus affecting the heat conduction and heat dissipation effect. , so people will fill the thermal gap between the heat source and the heat sink.

Thermally conductive gap filler is a new type of material that solves the problem of thermal conduction in equipment. , thermally conductive silicone grease, carbon fiber thermally conductive pad, etc. The thermally conductive material is mainly used between the radiator and the heat source, the air in the gap is removed, and the contact thermal resistance between the two is reduced, so that the heat can be quickly transferred to the radiator through the thermally conductive material. This reduces the problem.
