Thermal grease is a heat dissipation material. It can enhance the heat dissipation purpose when used in the substrate. It is used in common notebooks, TVs, and refrigerators. Although the heat dissipation performance is outstanding, there are strict requirements on the use position. If you are not careful, it will be counterproductive.
Why does thermal grease have requirements on the use position?
The main purpose of thermal grease is to fill the gap to achieve the purpose of heat dissipation. When the heating element contacts the heat dissipation device, even if the surface is very smooth, there will be gaps when contacting. There are a lot of air in these gaps, which is not conducive to heat conduction. Thermal grease fills the gaps, so that the heating element and the heat dissipation device are fully in contact, thereby achieving rapid heat conduction.
Thermal grease is a thermal conductive material in a paste state for filling gaps in electronic components. It has no effect when used in other positions, so it has strict requirements on the use position.
Does thermal grease have high requirements for the use field?
The raw material parameters and physical properties of thermal grease determine the application field. Some thermal greases are suitable for CPU heat conduction, some are suitable for memory heat conduction, and some are suitable for power supply heat conduction. It is very important to buy a product with a wide range of applications and no restrictions on the application field. For example, TENSAN focuses on the research of thermal grease and provides customized thermal grease application solutions. It has a wide range of uses and can be applied to new energy, military, medical, aviation, shipbuilding, electronics, automobiles, instruments, power supplies, high-speed rail and other industries.
How is the temperature resistance of thermal grease?
Thermal grease has good temperature resistance. Products from major brands can achieve high and low temperature resistance. After use, it can also play an insulating and shockproof role. When applying, it should be noted that the more you apply, the better the thermal conductivity.
Thermal grease is a thermally conductive but non-conductive material. Some product formulas add silver powder or aluminum powder. Although the thermal conductivity is enhanced, the conductivity is also increased. Using it in electrical appliances increases the risk of electrical connection. Be cautious when purchasing products with such ingredients.
