The best thermal conductivity in the world is metal, not silicone grease, so why should we apply silicone grease? If the surface of radiator and CPU metal cover is as smooth as a mirror, then they can fully contact to achieve the best thermal conductivity. But this is impossible. The heat sink and the metal cover of CPU look smooth and smooth. In fact, with a magnifying glass, we can see many pits and holes in the metal surface, which lead to many holes in the middle of the contact surface. These holes are very obstructive to heat dissipation. Silica grease is a liquid, which can fill these ho...

The importance of choosing thermal conductive materials, such as thermal conductive silicone film, thermal conductive double-sided adhesive, thermal conductive graphite sheet and thermal conductive pouring sealant, is introduced.For thermal conductivity, whether active or passive cooling, it is very important to choose the appropriate thermal conductive material to select the appropriate thermal conductive material. Choosing the appropriate thermal conductive material and good thermal conductive material can form a good thermal conductivity efficiency and effectively transmit the heat of the c...

Thermal conductive silicone grease and soft thermal conductive silicone padSimple comparison between thermal conductive silicone grease and soft thermal conductive silicone pad1. Thermal conductivity: The thermal conductivity of thermal conductive silicone grease is higher than that of soft thermal conductive silicone gasket, which is 4.0-5.5w/m.k and 1.75-2.75w/m, respectively.2. Insulation: Due to the addition of metal powder, the thermal conductive silica gel pad has good insulation performance. The electrical insulation index of 1 mm thickness is over 3000 volts.3. Morphology: Thermal cond...

In the end, only about 30-40% of the input energy is converted into light energy, while the remaining 60-70% of the energy is converted into heat energy mainly in the form of lattice vibration caused by non-radiation recombination.The higher the chip temperature, the stronger the non-radiative recombination and the weaker the luminescence efficiency. Because people subjectively think that high-power LED has no heat, in fact it does. There is so much heat that problems occur during use. In addition, many people who use high-power LED for the first time do not know how to solve the thermal probl...
