In a product application that requires heat dissipation,DC cooling fanThe working principle of is completed according to energy conversion, namely: electrical energy → electromagnetic energy → mechanical energy → kinetic energy. Its circuit principle is generally divided into various forms, the circuit used is different, the performance of the fan will be different.

The speed of the DC cooling electric fan depends on the voltage, the angle of the electric fan blade, the diameter, the number of electric fan blades and the bearing. So, what is the reason for the slow speed of the cooling fan?

The primary resolution conditions for the speed of the heat dissipation electric fan are the structure and parts of the electric fan, the friction of the bearing and the wind resistance of the blade angle. If the wind pressure of the cooling fan is insufficient, it will also affect the speed of the fan.

1. The external environment (such as wind and sand, high temperature and low temperature) will also affect the speed of the cooling fan.

2. Check whether the cooling fan does not need to be cleaned for a long time, because the accumulation of dust and impurities will make the fan work. Lowering the bottom speed requires more effort.

3. Check whether the cooling fan is installed correctly. If the installation is not correct, if the fan is loose, the fan speed will drop at the bottom.

There are six keys to the selection of DC fans:

First, select the policy that can complete the strong wind volume. Let's look at whether the strong wind value is what we expect.

Second. The selection can complete the small size of the policy. According to the environmental requirements of our use place to choose a small size cooling fan.

Third, the selection can complete the small noise policy. The height of the noise is always a standard for the quality of an electric fan. So this aspect should be carefully selected.

Fourth. The selection can complete the policy of less power consumption. Energy saving is a big policy for us to choose cooling fans.

Fifth. Select a long-term approach to the use of longevity. To be able to work long hours is our necessary choice.

Sixth, the selection of low-cost programmes. This is a very real problem
 

The above is the choice of DC fan hot fan problems encountered, for more information, please consult our official website!
