Not many people have actually come into contact with thermal conductive materials, because thermal conductive materials are auxiliary materials for handling equipment heat conduction problems. Generally, they are used between the heat source and heat sink inside the equipment. If someone who has assembled a computer has come into contact with thermal conductive materials, they need to apply thermal conductive silicone grease on the surface of the CPU before installing the heat dissipation fan.
The main function of thermal conductive materials is to fill the gap between the heat source and the heat sink in the equipment, eliminate the air in the gap, reduce the contact thermal resistance between the two, and enable heat to be quickly transferred to the heat sink through the thermal conductive material, thereby improving the heat dissipation effect.
Thermal conductivity is a parameter that measures the thermal conductivity of a material. When choosing a thermal conductive material, people often prioritize its thermal conductivity. The higher the thermal conductivity, the better the material's thermal conductivity. Of course, it is not enough to just look at the material's thermal conductivity. There are many parameters of thermal conductive materials, and thermal conductivity is the most intuitive way to judge the material's thermal conductivity. There are also many parameters that can affect the material's thermal conductivity.
Thickness, hardness, compression ratio, temperature resistance Many parameters can affect its performance, and thermal resistance in thermal conductive materials affects the thermal conductivity of the material. Thermal resistance is like an obstacle on a track, and when a person runs on the track, their speed will decrease due to the obstacle. The more obstacles there are, the slower the speed. Therefore, the less thermal resistance there is, the better the thermal conductivity of the material. There are also two types of thermal conductive materials, except for thermal resistance, all other parameters are the same. The one with lower thermal resistance has better thermal conductivity than the one with higher thermal conductivity.
