How Does The Thermal Silicone Adhesive Heat?
- Oct 30, 2017 -

Thermal Silicone Adhesive is a thermal medium used to reduce the Thermal Silicone Adhesive between the surface of the heat source and the contact surface of the heat sink. In the industry, can also be called Thermal Silicone Adhesive, thermal conductivity silicone pad, soft heat pad and so on. As electronic devices continue to integrate more powerful capabilities into smaller components, an increase in temperature can lead to slowdown in device operation, failure of device work, space limitations, and many other performance issues. So temperature control has become one of the most important challenges in the design, that is, in the structure of the tight, the operating space is getting smaller and smaller circumstances, how to effectively take away the greater power generated by greater unit power.

Soft Thermal Silicone Adhesive from the engineering point of view of how to make the irregular surface of the material match, the use of high-performance thermal conductivity material to eliminate the air gap, thereby enhancing the overall heat transfer capacity, the device at lower temperatures.

Thermal Silicone Adhesive rubber is a silicone resin as a bonding material, filled with thermal conductivity powder to achieve the purpose of conducting polymer composite materials, including the following materials:

Silicone resin (basic raw material)

Insulated Thermal Silicone Adhesive: alumina, magnesium oxide, boron nitride, aluminum nitride, beryllium oxide, quartz and other silicone plasticizer.

Flame retardant: magnesium hydroxide, aluminum hydroxide inorganic colorant (color distinction) cross-linking agent (bonding performance requirements) catalyst (process molding requirements)

Thermal conductivity of silicone film only play a role in thermal conductivity, heat generator and heat dissipation between the device to form a good heat conduction path, and heat sink, structural fixtures and other components together to form a cooling module.

How does the heat-conductive silicone film dissipate heat? In general, the heat dissipation is inseparable from the radiator: the fan and the heat sink, but many people ignore the middle of the thermal material, which contains not only thermal conductivity of silicone film, as well as thermal Silicone grease, thermal conductivity ceramic, Thermal Silicone Adhesive, thermal conductivity potting, thermal double-sided adhesive, and so on;

So how to heat the silicone film to play a cooling effect, we have to analyze, thermal conductivity of silicone film material is the thermal interface material, thermal interface: we can be understood as the heating surface and heat dissipation surface. The principle is through the Thermal Silicone Adhesive to fill the gap between the two sides, so that heat from the heating surface to the rapid delivery of heat to the surface, so as to achieve the purpose of cooling, but also play insulation, shock absorption, sealing effect.

Thermal Silicone Adhesive is mainly used in the control of electronic and electrical products motherboard, motor, external pad and foot pad, electronic appliances, automotive machinery, computer host, notebook computer, DVD, VCD and any need to fill and heat the module material, Said the application is very wide.
