Thermal resistance and thermal conductivity of thermal silicone pad

The vast majority of electrical appliances nowadays will generate heat during use, which is unavoidable, because the energy conversion process will be accompanied by loss, and heat will be generated when the current passes through the resistor. The higher the power of the device, the heat generated by it. The more it is, the slower the heat transfer rate in the air, and the narrower internal space of the device, the more difficult it is for heat to circulate, which easily leads to excessively high temperature.

As an excellent interface gap filling thermal conductive material, thermal silicone pad is generally used in the gap between the heat source and the heat dissipation module to eliminate the air in the gap, reduce the contact thermal resistance, and improve the heat transfer efficiency.Sheen's thermal silicone pad also can alternative Laird' thermal material.

Thermal conductivity is a parameter to measure the thermal conductivity of thermal silicone pad. The higher the thermal conductivity of the thermally conductive film, the better the thermal conductivity. At the same time, its price and its influence are proportional to the relationship between the two. Thermally conductive silicone film has many parameters, except for thermal conductivity. In addition to the coefficient, its own thermal resistance is also an important parameter, because the higher the thermal resistance, the higher the resistance to heat transfer in the thermally conductive silicone sheet. This is why the two types of thermally conductive silicone have other parameters in addition to thermal resistance, thermal silicone pad with low thermal resistance, its thermal conductivity is better.
