There are more DC fans used in electronic and electrical products than AC fans. Why does everyone use AC fans less? This is mainly caused by the following reasons:
1. The DC fan has high safety performance, DC5V, DC12V are directly touched, and there is no dangerous injury
2. The DC fan is convenient to obtain electricity, not only through the mains voltage transformation, but also through the battery. The USB interface on the car and the computer also has 5V power.
3. The DC fan can be designed to be very small and thin
4. The blades of the DC fan are longer and larger than the AC fan of the same model, and the air volume is larger
5. The DC fan is quieter under the same air volume
6. The cost of DC fans is lower
