Relative concept Micro Cooling Fan

Date: 2015-3-11   Click: 1447 Times

"Micro Cooling Fan" air volume and pressure are two opposing concepts. In general, to design air volume fan, it is necessary to sacrifice some pressure. If the fan can bring a lot of air flow, but the pressure is small, the wind can not blow the bottom of the radiator (which is why some high fan speed, air volume is large, but the cooling effect is good reason). In contrast, large pressure, air flow is small, there is not enough cold air and heat exchange fins, can also cause "Micro Cooling Fan" cooling effect is not good. General requirements of aluminum fin heat sink fan pressure is large enough, and the copper heat sink fin fan air volume is required to be large enough; more dense fin heat sink fins relatively sparse compared to the heat sink, the need greater pressure of "Micro Cooling Fan", otherwise poor air flow between the fins, the cooling effect will be greatly reduced.
