Cooling fans are widely used in various industries with high market demand, which has led to an increasing number of cooling fan manufacturers. Some manufacturers, in order to save production costs, pass off inferior products in the production of cooling fans, and consumers may accidentally buy inferior products. To avoid this situation, today Shenzhen Yingtian Electromechanical Equipment Co., Ltd. will introduce it to you How to determine the quality of a cooling fan?

The quality of the cooling fan can be judged from the following aspects:

1. Appearance framework

The frame of a typical cooling fan is made of plastic or aluminum alloy materials. Generally, AC fans are made of aluminum alloy, while DC fans are made of plastic. For cooling fans with aluminum alloy frames, the central axis inside is very important. A good central axis is made of copper, while a poor one is made of aluminum alloy.

2. Circuit board

A high-performance cooling fan will be more complex in circuit board design and require many parts, while a poorly performing cooling fan will be simpler in circuit board design and require relatively fewer parts.

3. Copper wire

Good cooling fans use relatively rough and sturdy copper wire, which is manually wound, while poor cooling fans use very fine copper wire, but this is only relative to the same product. Generally, the smaller the fan, the thinner the copper wire will be.

　4. Bearing

Usually, there are two types of cooling fans: ball bearings and oil containing bearings. Ball bearings are much easier to use and have a longer service life than oil containing ones.

5. The material of the fan blades

Good cooling fan stators are usually made of medium steel, which is very sturdy and the fan blades are durable, while poor cooling fan blades are relatively thin and prone to cracking or breaking.
