Thermal conductive silicone grease filler, an ideal material for electronic devices with high temperatures
Thermal conductive silicone grease is a composite of thermal conductive organic silicone grease made by adding heat-resistant and excellent thermal conductive fillers, commonly known as heat dissipation silicone grease or heat dissipation paste.
During the operation of electronic devices, a large amount of heat is generated. If operated in a high-temperature environment for a long time, the performance of the device may decrease, its lifespan may be shortened, or it may even burn out. To effectively solve the problem, we can use thermal conductive silicone grease as a material to help the heating chip of the device dissipate heat. Thermal conductive silicone grease has excellent performance in heat dissipation and can meet the heat dissipation needs of different electronic devices. In addition, it has good stability, anti-aging performance and high and low temperature resistance, which can play a good heat dissipation effect under various environmental conditions, thus extending the service life of the equipment.
Compared with traditional thermal conductive materials, when using thermal conductive silicone grease, it is necessary to choose the appropriate material model and thermal conductivity, and master the correct construction method. Meanwhile, during storage, avoid exposure to sunlight and high temperatures to prevent material aging and performance degradation.
1、 Thermal conductivity coefficient
The thermal conductivity coefficient is one of the important indicators in the application process of thermal conductive silicone grease. Generally, users cannot directly test it, but confirm the heat dissipation effect through whole machine testing. However, these effects are short-lived and there is no obvious difference. After application for a long time, the thermal conductivity effect may not keep up, leading to premature product failure. Therefore, when selecting thermal conductive silicone grease, actual test values should be selected instead of theoretical values. When selecting thermal conductivity coefficient, relevant parameters such as test area, heat flow rate, thermal resistance, pressure, and average temperature should also be understood.
2、 Consistency
Consistency is an important indicator of the operability of thermal conductive silicone grease, usually manifested through fineness, viscosity, and cone penetration. Fineness requires the production of thermal conductive silicone grease without particles, which can lead to uneven contact surfaces and difficulty in scraping; The higher the viscosity or the lower the cone penetration of thermal conductive silicone grease with the same thermal conductivity, the greater the difficulty of operation. Therefore, after confirming the thermal conductivity, it is necessary to compare the operability to avoid affecting production efficiency.
3、 High temperature aging
To ensure the stability and reliability of thermal conductive silicone grease during the expected service life of the product, it is necessary to have knowledge about aging. Mainly focusing on two aspects, first, the degree of thermal conductivity attenuation of thermal conductive silicone grease after aging; Secondly, what is the volatility and oil yield of thermal conductive silicone grease after aging; By confirming these issues, it can be basically determined whether the thermal conductive silicone grease will fail prematurely during use.
Overall, thermal conductive silicone grease is an ideal thermal conductive material that can effectively solve the problems caused by high temperatures in electronic devices. This material has high thermal conductivity, stability, and resistance to high and low temperatures, providing a strong guarantee for the stable operation of electronic devices.
