[Abstract]:
Thermal silica gel is a product that is progressing in the market of thermal foams, mainly made of silicone, to reduce the contact resistance between the heat source surface and the heat sink interfac

Thermal silica gel is a product that is progressing in the market of thermal foams, mainly made of silicone, to reduce the contact resistance between the heat source surface and the heat sink interface. Specifically for the use of the gap to pass the heat of the design of the production program, to fill the gap to complete the heat and heat dissipation parts of the heat transfer, but also play insulation, shock absorption, sealing and so on, is an excellent thermal filler. The use of the field is also very wide, as long as the machinery, in the case of braking will be hot, good thermal performance of the product is much sought after by the mechanical manufacturers. This kind of thermal silicone film for the development of precision machinery, in the progress of science and technology, the traditional thermal glue has been unable to meet the current demand for precision instruments, therefore, on the basis of traditional manufacturers of thermal film developed by the larger Market prospects.

Thermal conductivity silicone film for the control of electronic products motherboard, motor, external pad and foot pad, electronic appliances, automotive machinery, computer host, notebook computer, DVD, VCD, all kinds of lamps and any need to fill and cooling module material. Thermal conductivity of silicone is a high-end thermal conductivity compounds, and will not be solid, not conductive characteristics can avoid such as circuit short circuit and other risks; its high bonding performance and superior thermal effect is the current CPU, GPU and heat sink contact Of the thermal solution.

Thermal conductivity of silicone can be widely coated in a variety of electronic products, electrical equipment in the heating body (power tube, SCR, electric reactor, etc.) and cooling facilities (heat sink, heat sink, shell, etc.) between the contact surface, From the role of heat media and moisture, dust, corrosion, shock and other properties. It is suitable for surface coating or whole potting of various microwave devices such as microwave communication, microwave transmission equipment, microwave special power supply, power supply and so on. Such silicon material provides excellent thermal effect to produce hot electronic components. Such as: transistor, CPU assembly, thermistor, temperature sensor, automotive electronics parts, car refrigerator, power module, the first printer.

The main purpose of selecting the thermal silicone film is to reduce the contact resistance between the heat source surface and the heat dissipating device contact surface.The thermal conductive silicone film can fill the gap of the contact surface well, squeeze the air out of the contact surface and the air is the bad conductor , Will seriously hinder the heat between the contact surface of the transfer; with the thermal silicone film supplement, you can make the contact surface better full contact, really face to face contact in the temperature reaction can reach as little as possible the temperature difference. Thermal conductivity of the thermal silica gel is relative, although its thermal conductivity in the flexible material is better, usually in the range of 0.6-1.5W / (m · K), a small number of performance may be higher, but no more than 2W / ( M · K).
