24V DC Cooling Fan Noise at Work mainly

Time:2014-12-11 Click:493Times

1. friction and vibration "24V DC Cooling Fan" bearing: not only produce noise, but also affect the performance and shorten the life of the device, reducing energy use efficiency 冺 is the key technical issues in product design as much as possible to solve.
2. vibrating blades "24V DC Cooling Fan": the general fan blades made of plastic has a certain toughness, can withstand a certain degree of physical strain, the same will in the process due to the vibration of air pushing force occurs, but the magnitude generally small. Another more serious vibration is due to the quality of the uneven distribution of the blades, and the rotation axis of the center of mass due to the presence of the eccentric distance. When the case fan area (quality) or larger eccentricity may be driven radiator fan even overall vibration occurs, and then spread to the entire chassis. If such a phenomenon occurs, the fan should be suspected quality and working condition.
3. "24V DC Cooling Fan" wind noise: the flow of air between each impulse interference occurs and the surrounding objects friction vane airflow separation, periodic pulse air force, etc., will produce noise. The faster the air flow, turbulence, the more often the wind
