The conventional treatment method is to fill the heat source and the heat sink with a thermally conductive material to fill the gap between the interface and remove the air between the gaps, thereby improving the heat transfer efficiency and improving the heat dissipation effect. This is also the main function of the 熱伝導性材料. Thermal conductivity is one of the parameters to measure the 熱伝導性材料. The greater the thermal conductivity, the stronger the thermal conductivity of the material.
There is an old saying in the industry: purchases look at thermal conductivity, and engineering looks at thermal resistance. Most purchasers will use the thermal conductivity as a reference when choosing 熱伝導性材料 , but engineers’ opinions are different, although thermal conductivity is a measure of material thermal conductivity. Performance, but there are also other parameters that affect its performance, such as thermal resistance.
Every kind of 熱伝導性材料 has thermal resistance. The smaller the thermal resistance, the better the thermal conductivity of the thermally conductive material, and vice versa. Why is this?
Simple explanation: a water pipe connecting two ports, the larger the water pipe, the greater the water flow that it can pass through, which also means the more water can circulate at the same time, but the water pipe has some scale, and the more scale, The more it hinders the flow of water, which results in slower water flow. Then compare the size of the water pipe to the thermal conductivity of the 熱伝導性材料 , and the scale to thermal resistance. It can be concluded that the smaller the thermal resistance, the better the thermal conductivity. Why different thermal resistance, other 熱伝導性材料 with the same parameters, the smaller the thermal resistance, the better the thermal conductivity.
