Waterproof Cooling Fan noise level

Date: 2015-3-4   Click: 1439 Times

"Waterproof Cooling Fan" system impedance: air flow resistance will cause the air flow generated noise.
Turbulent flow: the flow channel due to poor design will cause air turbulence frequency noise occurs, if the runner does not improve very difficult to have a qualitative improvement.
"Waterproof Cooling Fan" The speed and size: the fan speed cooling effect sooner the better, the larger the size of the fan air flow the greater the cooling fan, the better. The larger the fan speed, the higher the noise, the greater the larger the size of the noise.
Increase in temperature: the temperature rise the temperature difference decreases, 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.
"Waterproof Cooling Fan" Design considerations: Some other requirements for design must also be taken into account to ensure that the effect of the cooling fan.
