What is thermal conductive paste

When the computer shows that the temperature of a certain part is too high, people often clean the paste on the surface of the radiator and parts, and then apply new paste instead of directly replacing the radiator. Why?

The heat sink is in direct contact with the surface of the heat source, and the heat transfer efficiency in the air is lower than that of the solid. When heat is transferred between the two, it is hindered, thereby reducing the heat transfer efficiency. The heat sink and the surface of the parts are filled with thermal paste, which can fill the gaps between the two, allowing heat to be quickly transferred to the heat sink, thereby improving the heat dissipation effect.

The application range of thermal conductive paste is very wide, suitable for most devices with heat conduction problems. Its operation is convenient, just clean the surface to be coated, and then apply a thin layer of thermal conductive paste on it. So, what kind of thermal conductive material is thermal conductive paste specifically?

Thermal conductive paste is a semi fluid paste like composite material based on silicone resin, which has high thermal conductivity, low thermal resistance, and excellent interface lubrication performance. It can form an extremely thin interface layer at rough interfaces, making it easy for secondary rework. It is commonly used to fill the gaps between power consuming electronic components and heat sinks, improving the thermal conductivity efficiency of heat sinks and is widely applicable in the current industrial process field.

In addition to thermal conductive paste, there are thermal conductive silica gel sheet, thermal conductive gel, thermal conductive phase change sheet, thermal conductive insulation sheet, carbon fiber thermal conductive gasket, silicon free thermal conductive gasket, etc. on the market. Customers can choose according to the operating environment of the product to effectively improve the heat conduction problem.
