DC Cooling Fan can be widely used in various fields, many equipment have the application of cooling fan, in mechanical equipment after long-term use will produce too much heat energy, serious will affect the normal use of equipment, does the fan make noise when it is running, and what is the cause of the noise from the DC cooling fan?

 The noise of a fan sounds like a simple fan, but the noise of a fan is different. When the fan is running, if there is any other sound besides the wind, you can tell that there is a noise in the fan. Abnormal sound may be due to a foreign body in the bearing or deformation, as well as improper assembly and collision, or motor winding is uneven, resulting in loose, may produce abnormal sound. 

2. Wind noise, when the fan works, because the blade is periodically subjected to the pulsation force of the outlet non-uniform air flow, the noise is produced: On the other hand, because the blade itself and the uniform distribution of the pressure on the blade, the rotating noise is also caused by the disturbance of the surrounding gas and parts. 

3. Vibration, if the physical center of mass of the Rotor and the inertia center of the rotor are not on the same axis, the DC cooling fan manufacturers will cause the rotor imbalance. 

The above is a brief introduction of what causes the noise of DC cooling fans in Dongxingyue. When choosing DC COOLING FANS, choose a guaranteed manufacturer, with quality and after-sales guarantee, a good DC cooling fan determines the normal operation of the equipment, but also to extend its service life, efficiency also increased, if you want to know more DC cooling fan knowledge can pay attention to us http://www.dxymotors.com。
