What are the main parameters for selecting DC cooling fans?

1. To determine the DC fan voltage, ask the supplier to set an acceptable size range based on the voltage for the speed of the two fans and provide samples. After testing with electricity, there will be three results. If-if the test is OK, it's better. We can adjust the DC fan if the wind is small or noisy.
2. If the wind volume is small, then we can slowly increase the adjustable power supply voltage, power the miniature fan, and the speed will slowly increase. The wind volume will increase until we confirm that the wind volume of the DC fan can meet the requirements of the equipment. And record the voltage at this time.
3. The noise is very large. We can reduce the voltage of the DC fan in the same way. The speed ratio will be reduced, the noise will be reduced, and the voltage will be recorded.
After testing the above steps, provide the DC fan supplier with samples and voltage values, record the speed at the current voltage, and make another sample. Basically, it's okay. If these three steps still fail, we can start with the first step and ask the supplier to make another size sample. However, with the experience of the first sample experiment, the chance of success is greater.
Thank you for reading. We will continue to publish fan cases and knowledge in industrial fans.
