DC cooling fan, a kind of cooling equipment commonly used to reduce the temperature of the working environment of the equipment and prolong the service life of the equipment, which is mainly composed of four parts: rotor, stator, motor and outer frame. Its rotor and stator are its core components, which form a magnetic field to attract each other and run after energized. The motor diameter and blade curvature of the DC cooling fan will affect the fan's air volume and air pressure, the higher the motor power the larger the diameter needed. The curvature of the blades also affects the fan's air delivery interval and air pressure, and a slight curvature ensures that the airflow is concentrated.

Advantages of DC cooling fans include:

1. Good heat dissipation: DC cooling fan drives the blades to rotate through DC voltage and electromagnetic induction, which is characterized by good heat dissipation and fast speed.

2. Fast speed: DC cooling fan rotates quickly, which can quickly reduce the temperature of the working environment of the equipment.

3. Long life: DC cooling fan has a long service life and can run stably for a long time.

4. Simple control: the control circuit of DC cooling fan includes many half-parts, which can be stored in the DC conductor cooling step, simple control.

5. Low cost: the cost of DC cooling fans is relatively low, suitable for a wide range of applications.

6. Wide application: DC cooling fan is widely used in various equipments, such as computers, automobiles, communication equipments, purifier industry, ups power supply, medical equipment industry and so on.

7. Convenient maintenance: DC cooling fans require regular lubrication, cleaning and storage for easy maintenance.

Overall, DC cooling fan is a kind of efficient, stable and easy to maintain cooling equipment, with a wide range of application prospects.
