Inventory of misconceptions about thermal paste


When electronic components are working, they often encounter heat dissipation problems. Although there are radiators, in order to achieve the ideal heat dissipation effect, they are now filled with thermal paste. After filling the thermal paste, the heat dissipation speed is fast and it can also prevent dust.

Misconceptions about thermal paste:

1. Thermal paste can prevent dust and have adhesive properties. This concept is wrong. The thermal paste is in the state of grease. No matter before or after use, the state remains the same. After being applied to the substrate, it can be adhered to the surface, but it has no adhesiveness and can be easily removed with a paper towel or scraper. .

2. Although thermal paste has good thermal conductivity, it is easy to connect to electricity. The reason for this kind of thinking is that there is too little understanding of the performance of thermal conductive paste. Although thermal conductive paste is a thermally conductive material, it does not have any electrical conductivity. It has high insulation performance and is an insulating material.

3. If you want to have a good heat conduction effect, you should apply more. When applying thermal paste, if the applied layer is thicker, not only will it fail to achieve thermal conductivity, but it will also be counterproductive. The principle of using thermal paste is to fill the gap, so that the heater and the heat dissipation device are fully connected.

4. The thermal conductivity of thermal paste is the same. In fact, this is not the case. The thermal conductivity of thermal paste needs to be determined according to the adaptability of electrical appliances, and the thermal conductivity of different brands is also different. At present, there are many kinds of thermal conductivity of the same thermal paste on the market for customers to choose from. If there is no suitable The thermal paste can be customized, and the current brands can be customized for customers, such as TENSAN, which focuses on the research of thermal paste and provides customized thermal paste application solutions. It has a wide range of uses and can be used in new energy, military industry, medical treatment, and aviation. , ships, electronics, automobiles, instruments, power supplies, high-speed rail and other industries.

Thermal paste will not solidify during use, but there will be slight oil separation, which is normal. The thermal paste can only be used between the electrical heating element and the heat dissipation facility, and it has no effect when applied to other positions.
