Cooling fans have a wide range of applications. The most commonly used places include chemical, light industry and other aspects, and they are also very good for applications in buildings and homes. Cooling fans have many functions and large types. Each cooling fan has its own unique role. .
u003cbru003eBut for car heat dissipation, it is necessary to choose a good cooling fan, otherwise noise will appear and it will have a certain impact on the performance. In order to avoid errors in the performance, how should the car cooling fan avoid noise?
u003cbru003eThe noise of automobile cooling fans is related to friction and air flow. The higher the fan speed and the greater the air volume, the greater the noise caused, and the vibration of the fan itself is also a factor that cannot be ignored.
u003cbru003eOf course, the vibration of a high-quality cooling fan will be very small, but the first two are difficult to overcome. To solve this problem, we can try to use a large-sized high-power cooling fan.
u003cbru003eWhen the air volume is the same, the working noise of a large fan at a lower speed should be smaller than that of a small fan at a high speed. Another factor that we easily overlook is the bearing of the fan.
u003cbru003eBecause of the friction and collision between the shaft and the bearing when the cooling fan rotates at high speed, it is also a main source of noise of the cooling fan.
