Supply of thermal silica films

 High-end thermal compound thermal silica Supply of thermal silica films is not solidified and not conductive characteristics such as to avoid the risk of a short circuit and the like; its high adhesion properties and superior thermal effects is the CPU, GPU and heatsink the best thermal solution for contact. Thermal silica can be widely applied to a variety of electronic products, electrical equipment contact surface heating element (power transistor, SCR, electric reactor, etc.) and cooling facilities (heat sink, cooling section, housing, etc.), and Heat and moisture from the role of the media, dust, corrosion, shock and other properties. Selection of thermal silica film main purpose is to reduce the contact thermal resistance between the heat source and heat sink surface in contact surfaces. Thermal silica film can be a good gap-filling the contact surface, the contact surface of the air out of the air is a poor conductor of heat, will seriously hamper the transfer of heat between the contacting surfaces; with complementary thermal silica film, you can make contacts Better face full contact, truly face to face contact. The reaction in the temperature can reach temperature differences as small as possible. Thermal effects of thermal silica is relative, though in its flexible material better thermal performance, usually within 0.6-1.5W / (m · K) range, a small number of performance may be higher, but not more than 2W / ( m · K). 0.5 compared to water, 0.22 vulcanized rubber, petrolatum 0.184 [1], and so is higher. But and cement 1.5W / (m · K), there is no advantage. The thermal conductivity of almost all metals, are much higher than thermal silica. Thermal conductivity of metals of gold, silver, copper between 330 ~ 360, the thermal conductivity of aluminum is about 200. Thermal silica itself is not a good conductor of heat, thermal silica role is to bridge the gap between the heat source and heat sink. So the use of the thermal conductivity of silicon is as thin as possible, to smear thermal silica 0.1-0.5 mm thick to fill the gap, the effect is much better than 1 mm thick silica film.
