Micro Cooling Fan choice points

1. "Micro Cooling Fan" selection of the control parameters for air flow, total pressure, efficiency, noise, and electrical power. There are centrifugal and axial flow.
2 fans due to set up a wind chassis conducive silencer.
3. "Micro Cooling Fan" the selection, should consider piping system leakage losses, calculation errors, and negative deviations ventilator actual wind, air pressure, and the general air volume of 1.05 to 1.1, 1.10 to 1.15 of pressure safety factor. But do not use too much, in order to prevent long-term ventilator running at low efficiency area.
4 Note that the pipe network resistance characteristics matching relationship with the "Micro Cooling Fan" characteristics. For the stable operation of the fan, the fan should be working near its maximum efficiency, the operating point of the fan performance curve to the right of the peak point of the total pressure (ie, the amount of side winds, and generally at full pressure peak of 80% ).
