For a long time,people concern about ac cooling fan is not only a cooling effect,and the voice of the ac cooling fan is working size.In fact,the generation of ac cooling fan noise fators are various.
Influence of ac cooling fan noise and air contact friction and flow to a certain extent,under normal circumstances,the greater the speed of the fan,air volume is larger,also has the greater the friction,the noise is big,moreover the fan itself will vibrate in the process of work,also can produce a small voice.In order to reduce the generation of noise,produce a small voice.In order to reduce the generation of noise,professional researchers found that under the same air,ac cooling fan blades,the greater the need to speed the less,so the noise is the less.the noise from the ac cooling fan also comes from th fan bearing the impact.
