Micro Cooling Fan Radiation

"Micro Cooling Fan" radiation is due to the presence of a temperature difference between the thermal conductor and the adjacent material or space, so that the thermal conductor of heat will be sent out in the form of electromagnetic waves. The higher the surface temperature of the heat sink, the rougher the surface, the higher the rate of black surface, "Micro Cooling Fan" capacity radiator radiant energy is stronger. So most of the radiators have been black oxide treatment, is in order to increase the capacity of the thermal radiation. Conduction and convection, heat transfer is carried out by solid or liquid, and radiative heat transfer without any substance as a medium. "Micro Cooling Fan" heat radiation is electromagnetic radiation, due to its own temperature caused. Radiative heat transfer body therewith proportional to the absolute temperature. For radiation heat transfer, there is Stefan Boltzmann law exists.
