As cars become more and more common in life, cooling fans are also widely used in different cars. These automotive cooling fans need to be maintained after a period of time, which is conducive to long-term use and prolong the service life of the fans. The next content is to introduce some car cooling fan maintenance methods.

1. First of all, open the cooling fan shell, then open the cooling fan, and then turn off the power supply. Blow with an air gun at 3 cm away from the cooling fan. After blowing the dust off the surface, wipe the remaining dirt above the fan blades with industrial alcohol. From the front of the device to the back, it needs to be cleaned and then rotated repeatedly until it is clean.

2. There are many factors affecting the wind speed of the automobile cooling fan, among which the most important factor is the bearing of the cooling fan.

Ball bearings: Long-term oxidation and accumulation of dirt and dust of the bearings of ball bearing exhaust fans will increase the friction resistance of the bearings and gradually reduce the fan speed.

Oil-bearing: With the longer the use time of the cooling fan of oil-bearing, the oil in the bearing gradually decreases, resulting in the speed of the cooling fan becoming slower.

The bearings of the cooling fans rotate repeatedly when they are used, which will shorten the life of the fans as well as produce wear. So we need to maintain the bearings of the automobile cooling fan in different ways according to the characteristics of different bearings.

3. The intake network port of the automobile cooling fan should be kept clean to prevent airflow obstruction. The intake network port can be cleaned with a soft brush or compressed air.
