The radiator and the heat source transfer heat through contact, but there is a gap between the contact surface of the heat sink and the heat source, and a greater pressure cannot be applied in time to achieve a complete fit. The air in the gap will hinder the heat transfer efficiency and reduce the heat dissipation. Therefore, it is necessary to use a thermally conductive material to fill the gaps, eliminate the air in the gaps, improve the heat transfer efficiency, and improve the heat dissipation effect.
Thermally conductive silicone sheet is a kind of gap-filling thermal pad made of silicone resin as the base material and added with temperature-resistant and thermally conductive materials. It has the characteristics of high thermal conductivity, low thermal resistance, insulation, compressibility, etc., because it is more The soft hardness makes it possible to realize a small thermal resistance under low pressure conditions, and at the same time eliminates the air between the contact surfaces and fully fills the rough surface between the contact surfaces to improve the heat conduction effect of the contact surfaces. Because of the good filling effect of the Thermally conductive silicone sheet, it can effectively conduct the heat of the heat source to the shell, and the thermally conductive silicone sheet has good compressibility and elasticity, and can serve as a shock-absorbing pad.
As a commonly used thermal conductive material, Thermally conductive silicone sheet is widely used in various industries. The thermal conductivity is a parameter to measure the thermal conductivity of the material. The higher the thermal conductivity of the thermally conductive silicone sheet, the better the thermal conductivity. The current conventional The thermal conductivity of thermally conductive silicone film is 1-6W/MK. However, with the development and progress of science and technology, thermally conductive silicone film with conventional thermal conductivity can no longer meet the current heat dissipation needs. It is necessary to use thermally conductive silicone film with higher thermal conductivity. Sheen, Dongguan City The SF Thermally conductive silicone sheet under New Material Technology Co., Ltd. has a thermal conductivity of 1-12W/MK. The product has passed a 1000-hour reliability test, and the enterprise system certification is complete. Welcome to consult.
