Mini Air Cooling Fan major issues

Date: 2014-10-8   Click: 1468 Times

"Mini Air Cooling Fan" process in order to reduce the use of low-noise must note the following:
System Impedance: air flow resistance will cause the air flow noise generation. Air turbulence: due to poor air flow channel design turbulence caused by the high-frequency noise will occur, if the stream channel does not improve very difficult to have a qualitative improvement. "Mini Air Cooling Fan" of speed and size: the cooling effect of the fan speed, the faster the better, the greater the larger the size of the fan air flow, heat the better. Fans turn The higher the speed the greater the noise, the larger the size the larger the noise. Increase in temperature: the temperature difference between the temperature rise is reduced, the cooling effect is reduced. Vibration: Vibration can cause the fan noise rise, reducing life expectancy and reduce speed. "Mini Air Cooling Fan" Voltage fluctuation: voltage fluctuations can cause the fan speed changes so unstable and will generate additional noise. Design considerations: the design of a number of other requirements must also be taken into account to ensure that the cooling effect.
