Thermal grease is needed in the manufacture of electrical appliances or electronic equipment, so that the contact surface between the heating element and the heat dissipation facility can play a role in heat dissipation, so that the heating element of the electrical appliance can be at a stable temperature, and it is not easy to burn out electrical appliances. So what kind of electrical thermal grease is good?
The main components of thermal grease are organic silicone and materials with good heat resistance and thermal conductivity. Because silicone grease has insulating properties, it will have insulation and thermal conductivity properties when used on electrical appliances.
If the main component of thermal grease is insulator silicone grease, then the thermal conductivity will be much worse. Therefore, thermal greases are all semiconductors, and the cheap semiconductors are only silicon and some other metal compounds. Metal compounds are usually used in high-end silicone greases. There is a big difference in coefficients.
How can I buy a good thermal grease?
1. When buying thermal grease, you need to pay attention, don’t just look at the price blindly, the quality can’t be guaranteed if the price is low, at this time, you can cooperate with big brands and companies with good reputation, such as TENSAN, which focuses on the research of thermal grease, Provide customized thermal grease application solutions, which are widely used and can be used in new energy, military, medical, aviation, shipbuilding, electronics, automobiles, instruments, power supplies, high-speed rail and other industries. Such thermal grease is at least in quality There is a guarantee.
2. At the time of purchase, pay attention to whether the surface of the thermal grease will be dry after coating and whether it will be cured. If the thermally conductive silicone grease is cured after construction, it is not of good quality. The cured thermal grease is relatively poor in moisture resistance and thermal conductivity, and there is no guarantee. Good quality thermal grease will never cure after curing, and it will always be sticky.
The relevant content about thermal conductive silicone grease is the above. Although the use of thermal grease in electrical appliances is small and the metering for one-time use is not much, it plays a vital role in the service life and safety of electrical appliances. It is necessary to purchase quality good.
