220V Cooling Fan inlet and outlet

"220V Cooling Fan" in the inlet and outlet parallel; their performance ranged from axial fans and centrifugal fans, air volume, air pressure is also large; it out of the wind and into the wind with a tilt angle, if two fans in parallel , the air flow can spread to the entire system. In order to make the most efficient fan, the optimum operating point at 1/3 of the axial flow fan after fan characteristic curve, namely large amount of wind, the wind down of the range. If the cross-flow "dota2雷竞技下载 " air flow enough, it may also be part of the front third of that small amount of wind, air pressure high range, avoid unstable region in the middle; the optimum operating point of the fan centrifugal fan characteristic curve Fan cooling veneer thickness is the minimum distance from the fan-fold greater than 1;; the first 1/3 part, that the higher pressure range "220V Cooling Fan" of the outlet should be avoided where is on the front of personnel to operate the equipment ; cooling fan power shall not exceed 10% of the overall device power consumption.
