Help Micro Cooling Fan measure radiation

1) "Micro Cooling Fan" rougher surface heat, heat radiation is also stronger. Usually heating components should be coated with an outer casing shielding paint, painted surfaces of the fins rough black or colored paint; heat-sensitive components, often made of bright white surface in order to reduce the absorption of radiant heat.
2) increase the "Micro Cooling Fan" temperature difference between the radiator and the surrounding environment.
3) increase the surface area of the radiator.
These three methods of heat transfer are often co-exist, the heat transfer is multidimensional. Under specific conditions can ignore minor factors to simplify calculations. For example, the heat transfer of the semiconductor chip to the housing is mainly conduction, convection and radiation and conduction may be negligible compared, and if at high altitude conditions, convection in a secondary position, mainly "Micro Cooling Fan" heat conduction and radiation, etc. and so on.
