Safety of 220 v AC Cooling Fan

Date: 2015-9-16   Click: 1290 Times

"220V AC Cooling Fan" major issues: the use of the process in order to reduce low-noise must note the following: System Impedance: Air flow resistance will cause air flow noise generation. Airflow turbulence: due to poor design of the flow channel of air turbulence caused by high-frequency noise will appear, if it does not improve the flow channel is difficult to have a qualitative improvement.Fan speed and size: the cooling fan speed sooner the better, the greater the greater the "220V AC Cooling Fan" in size amount of wind, the heat, the better. The larger the fan speed, the higher the noise, the greater the larger the size of the noise. Temperature rise: after reducing the temperature difference between the temperature rise, the cooling effect is reduced. Vibration: vibration will cause the fan noise rise, reducing the "220V AC Cooling Fan" life and speed decreases. Voltage fluctuation: The voltage fluctuation will cause the fan speed changes, so that job insecurity and will generate additional noise. Design considerations: Some other requirements for the design must also be taken into account, in order to ensure the cooling effect.
