Although the heat will dissipate to the surroundings after being generated, most electronic products are not ventilated inside, and the heat is easy to accumulate and cause the temperature to rise, which affects the operation of electronic components. Electronic components are very sensitive to temperature, and high temperatures will cause them to fail. , and the aging speed of the material will be accelerated at high temperatures, so it is necessary to dissipate heat in time.

It is not feasible to only rely on the heat source itself to dissipate heat, and heat dissipation devices, such as cooling fans, heat sinks, and heat pipes, will be used. Relying on the mutual bonding of the two, the excess heat of the heat source is guided into the heat dissipation device, but there is a gap between the heat dissipation device and the heat source, and heat-conducting materials will be used.

The Thermally conductive material is a general term for a material that is coated between the heating device and the cooling device of the product and reduces the contact thermal resistance between the two. Thermally conductive silicone grease is one of the thermally conductive materials. As one of the most commonly used thermally conductive materials in the market, it has a high reputation. Compared with other heat-conducting materials, the first time many people come into contact with thermal-conducting silicone grease is to install a cooling fan when assembling a computer, apply thermal-conducting silicone grease on the surface of the CPU, and then attach the contact piece of the cooling fan to the surface of the CPU.

thermal grease has high thermal conductivity and low interface thermal resistance. When using it, simply apply a thin layer of thermally conductive silicone grease, and then install the heat dissipation device, which can quickly remove the air in the gap and reduce the interface thermal resistance, so that heat can pass through quickly. Thermally conductive silicone grease is conducted to the heat dissipation device, and thermally conductive silicone grease is easy to operate, can be reworked, and is cost-effective.
