Cooling Fan - How many kinds of Our Fan Bearing System?
Jul 02 , 2020
The fan bearing system of cooling fan is mainly divided into sleeve bearing and ball bearing, while ball bearing is divided into single ball bearing and double ball bearing. Sleeve Bearing Sleeve Bearing is sintered from a copper-based powder. The use of the sleeve bearing requires lubrication to reduce the number of sliding friction. It can be said that it is the most common bearing technology in...

What is the relationship between starting voltage and cooling fan?
Dec 14 , 2021
With the increasing use of cooling fans, many people are interested in the details of cooling fans. Some people will ask whether the low voltage will affect the cooling fans. Low voltage has no effect on the fan, it will only make the fan rotate at low speed, which can prolong the service life of the fan, but low voltage for a long time may damage the motor. Voltage includes starting voltage and o...

Use of axial fans and blowers
Dec 28 , 2021
In the cooling fan, the DC fan provides variable flow and the AC fan provides constant flow. In addition to AC power supply and DC power supply, cooling fans are usually classified according to the way air enters and exits the fan. In an axial fan, air enters and exits in the same plane. If the airflow leaves in different planes, this is called centrifugal design or blower. Natural convection cool...

Why the speed of DC cooling fan slows down?
Mar 26 , 2022
Why the speed of DC cooling fan slows down? The speed of the cooling fan is determined by voltage, fan blade angle, diameter, number of fan blades, bearings, etc. So what is the reason why the cooling fan slows down? The speed of the cooling fan is mainly determined by the structure and components of the fan itself, the bearing friction and the wind resistance of the inclination angle of the fan b...
