Safety of 220 v AC Cooling Fan

"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 "ios版雷竞技官网入口 " 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.
