What are the advantages of glass fiber reinforced thermal conductive silicone sheet?

The main reason for the heating problem of the equipment is that a part of the energy will be lost during the conversion process of the electric energy, and a large part of this part of the energy is dissipated in the form of heat, so the equipment will generate heat during operation, although this is normal Physical phenomenon, but too high temperature is a safety hazard, so you need to install a radiator to transfer heat to the outside.

The general heat dissipation system is composed of a radiator, power dissipation components and thermal conductive materials. If the radiator and power dissipation components alone, the heat dissipation effect is very poor, because no matter how closely they fit, there is a gap between the two, and the air in the gap is A poor conductor of heat, so the heat conduction efficiency is low, and the thermal conductive material can effectively fill the gap between the two, reduce the thermal resistance, and improve the heat conduction efficiency. There are many kinds of common thermal conductive materials, such as thermally conductive silicone film, thermally conductive phase change film, thermally conductive paste, thermally conductive gel, non-silicon thermally conductive film, thermally conductive insulating film, etc.

Thermally conductive silicone sheet is a kind of gap-filled 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 interface thermal resistance, insulation, compressibility, etc., because Its softer hardness makes it possible to realize a smaller thermal resistance under low pressure conditions, and at the same time eliminates the air between the contact surfaces and fully fills the rough surfaces between the contact surfaces, improving the heat conduction effect of the contact surfaces.

Thermally conductive silicone sheet itself is a soft and elastic thermally conductive gasket. Some customers need glass fiber reinforced thermally conductive silicone sheet due to their product design. What are the advantages of glass fiber reinforced Thermally conductive silicone sheet?

First of all, the strength of the thermally conductive silicone sheet becomes higher. According to the research surface, the thinner the thermally conductive silicone sheet, the lower its tensile strength, and it is easy to tear during installation or use. Therefore, the ultra-thin thermally conductive silicone sheet is generally selected The method of glass fiber reinforcement is adopted to improve the tensile resistance.

Then, glass fiber is a non-metallic inorganic material with excellent performance, with excellent chemical resistance, acid corrosion resistance, etc., so it can improve the stability of the Thermally conductive silicone sheet.

Secondly, the cost of glass fiber reinforcement is not high. Compared with the loss caused by the process of use, transportation and storage, the thermal conductive silicone sheet can improve its reliability after glass fiber reinforcement, thereby indirectly reducing the cost.
