Waterproof DC fan is a widely used device in computers, communication products, optoelectronic products, consumer electronics, automotive electronics, exchangers, etc. Its main function is to reduce the temperature of the working environment of the equipment and prolong the service life of the equipment. It converts electrical energy into mechanical energy through DC voltage and electromagnetic induction, and consists of a rotor and stator, whose direction of rotation is controlled by the Ampere's right-hand rule, and a Hall sensing assembly that acts as a synchronization-detecting device to control its continuous operation.

Advantages of waterproof DC fans include:

1. Waterproof: Waterproof DC fans are waterproof and can be used in high humidity environments, solving the problem of cooling outdoor water spots with heavy moisture. The fan can be rated up to IP68 with voltage from 5V-48V.

2. Efficient heat dissipation: The fan has a built-in sensitive temperature sensor, which enables the number of revolutions and current to change with the temperature, so that the heat dissipation effect can reach the best effect.

3. Low Noise: DC fans have the advantage of low noise and long life, and can be used in a quiet environment.

4. Long life: DC fans are characterized by fast rotation speed, good heat dissipation and long service life, and can be operated stably for a long time.

5. Easy to maintain: The advantages of AC fans are cheap and easy to maintain, which can be easily maintained and replaced.

6. Widely used: Waterproof DC fans are widely used in various devices, such as computers, communication products, optoelectronic products, consumer electronics, automotive electronics, exchangers and other fields.

Overall, the waterproof DC fan is a highly efficient, low noise, long life and easy to maintain device that can provide good heat dissipation in a variety of environments.
