24V DC Cooling Fan for low noise

Date: 2015-2-28   Click: 1525 Times

"24V DC Cooling Fan" system impedance: air flow resistance will cause the air flow generated noise.
Cooling fan airflow turbulence: due to poor air flow channel design turbulence caused by high frequency noise will occur, if the flow path is not difficult to have a qualitative improvement improvement.
Fan speed and size: the cooling fan speed sooner the better, the greater the larger the size of the fan air flow, cooling fans, the better. The larger the fan speed, the higher the noise, the greater the larger the size of the noise.
"24V DC Cooling Fan" rise in temperature: the temperature difference between the temperature rise is reduced, the cooling effect is reduced.
Vibration: Vibration can cause the fan noise increased life expectancy and reduced speed is reduced.
Voltage fluctuation: voltage fluctuations can cause the fan speed changes, so unstable and will generate additional noise.
"24V DC Cooling Fan" Design considerations: Some other requirements for design must also be taken into account to ensure that the effect of the cooling fan.
