Mini axial flow fan noise value
1, bearings, bearing the noise factors we should not be neglected, is one of the biggest part of the noise source, dual ball bearing in the general case of fan noise much larger than the oil bearing fan noise.
2, friction: when mini axial flow fan use time is too long, can appear etc. In some cases, this will cause the fan blades and fan, collision or friction to produce noise.
3, rotational speed, it is also a necessary factor, the higher the speed, the noise will grow accordingly.
4, air flow, fan blades during the rotation, is the resistance in the air, the faster the rotation, fan leaf area is larger, the greater the resistance, so the increase of noise will be no accident.
these are, of course, we cannot ignore the noise source, what we have to reduce the cooling fan noise little secret?
1, the regular dust with a soft brush to clean up the cooling fan.
2, cushion, in addition to fixed strong outside, still can increase thin cloth, rubber gasket, etc in the contact position buffer
3, combined with the corresponding lower fan speed
4, add lubricant to the cooling fan
5, choose quality, high credibility of the brand, good good expensive, good is expensive, in our cooling fan manufacturer with a cooling fan brands have to explain in detail at the top of some brands.
chi car professional do fan, agent JAMICON kaimei fan, AVC, macro fans in Taiwan, Japan's SANYO DENKI SANYO cooling fans, have their own research and development team, to provide the most professional, the most perfect technical support!
