DC Cooling Fan wide range of applications, some of the initial use of the installation method is not very familiar with, then look at the installation of DC cooling fan method. 

1. Remove the DC fan and check the circuit board and coil windings. Use The multimeter to check the quality of the three coil windings if not bad, then use the multimeter to check the quality of each component of the DC Fan Small Circuit Board. 

2. The mounting hole must be larger than the diameter of the fan. The mounting hole of the fan must be larger than the diameter of the fan. 

3. Don't leave a gap between the panel and the DC fan when installing it, as this will not give full play to the cooling effect. 

4. Drastic changes in wind direction and flow cross-section area can weaken the cooling effect, so try to avoid this. 

5. Install the box fan by inserting the bolt hole into the panel opening. Use The attached mounting screws and nuts to hold the box fan in place. Install the lid up and down, but install it as installed. 

The above is a brief introduction to the installation method of DC cooling fan by Dong Xingyue. It is very important to select a good DC cooling fan. It can not only make the equipment run normally, but also prolong its life and increase working efficiency, if you want to know more about DC cooling fan knowledge can pay attention to us.
