Thermally conductive silicone sheet introduction: Thermally conductive silicone sheet in the industry, also known as thermally conductive silicone pad, thermally conductive silicone sheet, soft thermally conductive pad, thermally conductive silicone gasket, etc., is specially produced for the design of using gaps to transfer heat and can fill gaps , to complete the heat transfer between the heating part and the heat dissipation part, and also play the role of insulation, shock absorption, sealing, etc., which can meet the design requirements of miniaturization and ultra-thin equipment. It is very good in manufacturability and usability, and the thickness is suitable Wide range, a very good thermally conductive filler material.
How does the thermally conductive silicone sheet play a cooling role
In general, heat dissipation is inseparable from radiators: fans and heat sinks, but many people ignore the heat-conducting materials used in the middle. The heat-conducting materials include not only heat-conducting silica gel sheets, but also heat-conducting silicone grease, heat-conducting ceramic sheets, and heat-conducting silicon rubber cloth. Thermally conductive potting adhesive, thermally conductive double-sided adhesive, etc.;
The heat-conducting silicone sheet material belongs to the heat-conducting interface material, and the heat-conducting interface: we can understand it as a heating surface and a heat dissipation surface. The principle is to fill the gap between the two surfaces with a heat-conducting silicone sheet, so that the heat can be fully and quickly transferred from the heating surface to the heat dissipation surface, so as to achieve the purpose of heat dissipation, and at the same time play the role of insulation, shock absorption and sealing.
Thermal silica film application range
It is mainly used in control boards of electronic and electrical products, backing plates and foot pads inside and outside motors, electronic appliances, automotive machinery, computer hosts, notebook computers, DVDs, VCDs and any materials that need filling and cooling modules.
Factors Affecting Thermal Conductive Silicone Sheet
In the use of thermally conductive silicone sheets, pressure and temperature are mutually restrictive. As the temperature rises, after the equipment has been in operation for a period of time, the thermally conductive soft sheet material will soften, creep, and stress relax, and its mechanical strength will also decrease. , the pressure of the seal decreases, and vice versa.
It has good elasticity and recovery, and can adapt to pressure changes and temperature fluctuations;
It has proper softness and can fit well with the contact surface; it does not pollute the process medium; it has sufficient toughness without causing damage due to pressure and fastening force; it does not harden at low temperature and has a small shrinkage; it has good processability, It is convenient to install and press; it does not stick to the sealing surface and is easy to disassemble; it is cheap and has a long service life.
