Micro Cooling Fan air-cooling principle

From "Micro Cooling Fan" thermodynamic point of view, the object of endothermic, exothermic is relative, where there exists a temperature difference, it is bound to heat transfer from the high temperature occurs at low temperature, which is the nature of art and engineering a very common phenomenon. The way "Micro Cooling Fan" heat transfer in three ways: radiation, convection, conduction, which is the fastest heat conduction. Air cooling we have to discuss is actually forced convection cooling. Convective heat transfer that is dominated by the thermal conductivity of the law, but also by the laws of fluid flow domination, "Micro Cooling Fan" belongs to a complex process of heat transfer, convective heat transfer performance factors more.
