Thermal grease is a kind of pasty substance mainly made of organic silicone as the main raw material, and then adding some heat-resistant and thermally conductive materials. This substance can be used in electrical and electronic manufacturing, and can play a role thermal performance.
Heat dissipation principle of thermal grease:
Thermal grease itself is a paste-like substance, which needs to be applied on the contact surface between the heating element of the electrical appliance and the heat dissipation facility to exert its heat dissipation performance, ensure the temperature balance of the heating element of the electrical appliance, and conduct excess heat energy away. If it is applied to other places, there will be no heat dissipation effect, and it may even be counterproductive, affecting the normal operation of other electrical components.
Does thermal grease have other properties besides thermal conductivity?
1. In addition to thermal conductivity, thermal grease also has dust-proof and moisture-proof properties, because after applying heat-dissipating silicone grease, a protective film similar to the middle layer will be formed on the surface, which will not cure, so that it can achieve the purpose of dust prevention.
2. In addition to thermal conductivity, thermal grease also has anti-shock performance. When electrical appliances are turbulent, thermal grease can reduce vibration because of its paste-like nature, prevent parts from rubbing against each other, and effectively protect electrical components.
3. Good quality thermal grease also has good insulation performance, but the level of insulation performance is related to the quality of thermal grease, poor quality may also have insulation performance, and its insulation index is relatively low. If you want to buy thermal grease with high insulation index, you need to cooperate with big brand products, such as TENSAN, which focuses on the research of thermal grease and provides customized thermal grease application solutions. It has a wide range of uses and can be used in new energy, Military, medical, aviation, shipbuilding, electronics, automobiles, instruments, power supplies, high-speed rail and other industries.
Now thermal grease has various properties, not only has thermal conductivity, but also has other properties, so as to meet the requirements of various modern electrical appliances.
