| Thermal conductive silicone grease: also called thermal grease. It is a paste made of special silicone oil as the base oil, new metal oxide as the filler, with a variety of functional additives, and processed by a specific process. The color varies depending on the material Appearance. It has good thermal conductivity, temperature resistance, and insulation properties. It is an ideal dielectric material for heat-resistant devices and has stable performance. It will not generate corrosive gas during use and will not affect the metal in contact. The role of silicone grease is to fill the gap between the radiator and the chip. Take the well-known CPU and its radiator as an example. In fact, our seemingly smooth surface is actually ditch in a microscopic state. The surface of the CPU can be seen by our naked eyes. Polish the traces, and Limin, who is a radiator, can't escape the fate of pits. , Normal disassembly and assembly, plus the original polished lines, will make the radiator become a "moon surface". The uniform and appropriate thickness of silicone grease can fill these holes, make it more closely contact, increase the heat dissipation area, and improve the heat dissipation effect. The thermal conductivity of the silicone grease itself also determines the final practical effect. The application of silicone grease is actually not difficult. The focus is on two words, "even" and "thin". Here to correct a wrong concept, that is, silicone grease is not better if it is thicker, but if it is thinner. The editor recommends applying the method in the picture above, because the finger feel is very accurate. Although there is a special scraper, it is really not easy to use that thing well. |
