The role and type of thermal gap filler material

Contact with heat surface heat radiator is the mainstream way of heat dissipation, solid surface and surface contact heat transfer is better than air, but there are still problems, because the two touch each other solid surface, the actual contact is some discrete area, other did not contact interface in fills the air, heat through when the additional resistance, results in the decrease of heat transfer efficiency, This situation exists widely in reality.

In order to effectively reduce the contact thermal resistance between heat sink and heat sink, people have tried many methods, but the most effective method is to fill the thermal gap filler material between heat sink and heat sink to eliminate the air in the gap and improve the heat conduction efficiency. There are many heat conduction gap filling materials, such as thermal silicone pad, thermal gel, thermal silicone grease, heat conduction silicon tape, heat conduction phase change sheet, silicon-free thermal pad, carbon fiber thermal pad, heat conduction absorbing material and so on.

The types of thermal gap filler material are different, and they are good at different applications. If thermal silicone grease and thermal gel are used in many cases with very small tolerances, and they also have good application experience in the case of plane irregularity. Thermal conductive silicone pad, as a kind of thermal conductive gap filling material with high cost performance and excellent thermal conductivity, is used in all walks of life. Welcome to consult.
