Miniature radiator cooling fan noise cause and solution?
Miniature radiator cooling fan noise is mainly related to what factors?
We should be how to reduce the micro cooling fan noise?
Here by possessing YiRongChuan radiator cooling fan manufacturer of professional and technical personnel for you answer: 1, noise generated depends a lot on what factors?
Miniature cooling fan, air flow noise and friction.
The higher the speed, air volume, the greater the noise caused by the will, the greater the micro cooling fan's vibration is also cannot be ignored.
Of course high quality micro cooling fan of vibration will be small, but the two in front of the person is difficult to overcome.
2, how to measure the micro thermal cooling fan noise?
Noise is the size of the micro cooling fan is working to produce noise, affected by various factors, the unit is decibels (
Measuring micro cooling fan noise needs in the sound attenuation of noise is less than 17 db and cooling fan, one meter distance along the micro cooling fan rotation direction aim at the air inlet cooling fan, and is measured using A weighted way.
Miniature spectrum characteristics of cooling fan noise is also very important, so also need to use spectrometer to record the micro cooling fan noise frequency distribution, general requirements micro cooling fan noise to small, and can't exist different sounds.
3, how do we reduce the micro cooling fan noise?
To solve this problem, we can try to use the size larger cooling fan.
Should be under the same air volume, large heat dissipation fan noise at low speed when the work is smaller than small cooling fan noise at high speed work.
Another we are easy to overlook the factor is the miniature of the cooling fan bearing.
Due to micro cooling fan high-speed rotation to friction between the shaft and bearing during collisions, so also is the micro cooling fan is a major source of noise.
Above is about micro heat dissipation of the cooling fan noise causes and solutions, the hope can help you, more about radiator cooling fan knowledge, pay attention to possessing YiRongChuan radiator cooling fan manufacturers, our technical staff will you for your detailed answers one by one, to provide you with the best quality cooling cooling fan products and after-sales service, free proofing, directly or indirectly from three days to the sample.
