Thermal grease has a good effect on heat dissipation. Many electrical appliances use it and it is very popular in the manufacturing industry. In order to meet market demand, thermal greases of different brands and specifications are divided into different fields of use. There are also general thermal greases. This type of thermal grease can be used in a variety of electrical appliances, such as CPUs, LEDs, routers, sensors, etc.
Can CPUs be used without thermal grease?
The CPU cannot be used without thermal grease because there are gaps between the CPU and the radiator. These gaps may be visible to the naked eye, but there is a lot of air in these gaps. Air is a non-conductor. If the CPU cannot fully contact the radiator, the heat energy cannot be transmitted.
Although thermal grease is a thermally conductive material, its main function is to fill the gap so that the CPU and the radiator are fully in contact. There is no gap between the two, so that the heat energy can be transmitted in time, and the heat energy will not accumulate and burn the CPU.
Why does the CPU still burn after applying thermal grease?
The CPU has a good heat dissipation effect after applying thermal grease, but sometimes it may burn. The main reason is that the thermal grease contains metallic silver powder. Although this type of thermal grease has good thermal conductivity, it has poor insulation. The overflowed grease is easy to contaminate the surrounding relays, causing the relays to be contaminated, thereby causing electrical short circuits and even burning. At present, the brand of thermal grease not only has good thermal conductivity but also has insulation. 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.
Thermal grease is of great importance in the field of electrical manufacturing. It is an irreplaceable product. As long as the electrical appliances that need heat dissipation can be coated with thermal grease, it has a very wide range of uses. The product shelf life has been upgraded in production. The general warranty period is 3 years. As long as it is stored properly, there will be no problems.
