Mini Air Cooling Fan low noise must be taken to reduce the problem

Date: 2015-12-2   Click: 1462 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 air flow noise generation. "Mini Air Cooling Fan" 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 larger the size of the fan air flow, cooling effect is 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. "Mini Air Cooling Fan" Vibration: vibration will cause the fan noise increased, reducing life expectancy as well as the speed is reduced. 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.
