Heat sink area, the greater the heat dissipation effect is better?


the heat generated in the work is by conduction to radiator, bring the cold air blowing and then through the fan of the fin heat lead, and the heat conduction cooling fans can much related to the area size of heat sink, in general heat sink with the air of the contact area, the greater the fan cooling effect, the better, but that there is a premise, that is the case with enough under the condition of the remaining space, if a computer chassis space heat dissipation space is not large, originally without rest enough, are difficult to install a very large area of heat sink to the chassis, even if reluctantly installed in the chassis, the size of contact area will block the cooling in the hot air around quickly, resulting in casing internal optimal overall temperature is too high, that affect the performance of the whole car, so the morning of macro electronics technology co. , LTD. The proposal chooses the size of heat sink with case matching, can not blindly pursue large area of heat sink.
