What is AC & DC FAN
Cooling fans. The technology and performance of cooling fan have fully reached the mature stage, and new technologies continue to appear. The specifications and dimensions of the fan range from 8mm to 280mm. The voltages are 5V, 12V, 24V, 48V, 110V, 220V and 380V. The shape is square, round, olive, etc. The working principle of the cooling fan is realized according to the energy conversion, namely: electric energy → electromagnetic energy → mechanical energy → kinetic energy. The circuit principle is generally divided into various forms. The performance of the fan will be different with different circuits.

Noise of AC & DC Fan
In addition to the heat dissipation effect, the working noise of the fan is also a common concern. Fan noise refers to the noise generated by the fan during operation. It is affected by many factors, and the unit is dB. When measuring the noise of the fan, it needs to be carried out in the anechoic chamber with the noise less than 17dB, one meter away from the fan, align the air inlet of the fan along the direction of the fan rotating shaft, and measure it in A-weighted way. The spectral characteristics of fan noise are also very important. Therefore, it is also necessary to record the noise frequency distribution of the fan with a spectrometer. Generally, the noise of the fan should be as small as possible and there should be no abnormal sound.
Fan noise is related to friction and air flow. The higher the fan speed and the greater the air volume, the greater the noise will be. In addition, the vibration of the fan itself can not be ignored. Of course, the vibration of high-quality fans will be very small, but the first two are difficult to overcome. To solve this problem, we can try to use a larger fan. Under the same air volume, the working noise of large fan at low speed shall be less than that of small fan at high speed. Another factor we tend to ignore is the bearing of the fan. Because of the friction and collision between the rotating shaft and the bearing when the fan rotates at high speed, it is also a main source of fan noise.
