【 Auto cooling fan 】 Noise reduction is xiao
the cooling fan is now use range is very broad, this fan is used mostly in many aspects, such as chemical industry, light industry and in building families such as ventilation effect is also very good, the effect of the cooling fan and types, each of the cooling fan has its unique role. But for auto radiator, be about to choose a good cooling fan, or chasing a noise, have a certain impact on performance, in order to avoid the performance won't appear mistake, auto cooling fan should be how to avoid noise?
auto cooling fan, air flow noise and friction. Fan speed is higher, the air volume, the greater the noise caused by the will, the greater the other factors of the vibration of the fan itself is also cannot be ignored. High quality cooling fans, of course, its vibration will be small, but in front of the two is difficult to overcome. To solve this problem, we can try to use the size larger power cooling fan. Should be under the condition of the same volume, big fan work at low speed when the noise is smaller than small fan noise at high speed work. Another we easy to overlook the factor is the fan bearing. Due to the cooling fan to friction collision between high speed rotating shaft and the bearing, so is also a main source of cooling fan noise.
