熱伝導性界面材料の役割とは?

During the operation of electrical equipment, energy conversion is accompanied by consumption, and heat generation is its main manifestation. Equipment heat generation is inevitable. Electrical equipment is prone to failure in high temperature environment and may cause spontaneous combustion, so timely heat dissipation is necessary. , but the heat conduction effect in the air is very poor, directly exposing the heat source to the air to dissipate heat is neither effective nor safe, so a radiator will be used.

Installing a radiator on the surface of the heat source is a commonly used heat dissipation method. The heat conduction effect of plane-to-plane contact is much better than that of air conduction, but there is still a lot of non-contact area between the plane and the plane, and the heat will be transferred between the two. Affected by it, thermal interface materials are used.

The 熱伝導材料 is filled between the heat source and the heat sink to remove the air in the gap, thereby reducing the contact thermal resistance between the heat sink and the heat source, thereby improving the heat dissipation effect of the device. Thermally conductive phase change sheet, thermally conductive silicone cloth, silicon-free thermally conductive gaskets, carbon fiber thermally conductive gaskets and other thermally conductive gaskets, as well as thermally conductive silicone grease, thermally conductive gel, etc. There are different applications in different devices, so as to play their own role.
