DC fans, commonly known as electric fans, are an important type of industrial fans, widely popular for their wide range of applications and efficient heat dissipation. In electronic equipment, the application of DC fans is mainly through the conversion of electrical energy into kinetic energy, which drives the fan to rotate and realize the purpose of heat dissipation.

The working principle of DC fan is to convert electrical energy into electromagnetic energy through DC voltage and electromagnetic induction, which is then converted into mechanical energy to make the fan blade rotate. It is mainly composed of four parts: rotor, stator, motor, and outer frame, of which the stator and rotor are its core components. Inside the fan blades of a DC fan, there is a first-charged magnetic rubber magnet surrounding a silicon steel sheet, two sets of coils wrapped around the core of the shaft, and a set of circuits controlled by Hall induction components as a synchronization detection device to keep the fan blades in continuous operation.

In electronic equipment, DC fans are mainly used in the following areas:

1. Heat dissipation: DC fans can effectively reduce the temperature of electronic equipment to extend the life of the equipment. For example, the 12-volt DC centrifugal fan of Kunshan Shouken Electronics Industry Co., Ltd. has a wide range of applications in the fields of heat dissipation of electronic equipment, cooling of mechanical equipment, air filtration and purification as well as ventilation and heat dissipation by virtue of its high efficiency, low noise, long life and low maintenance.

2. Air filtration and purification: DC fan can draw air into the inside of the equipment by rotating, and through the filter mesh or other filtering devices, the dust, bacteria and other impurities in the air will be filtered out, so as to realize the purpose of air filtration and purification.

3. Ventilation and heat dissipation: DC fan can exhaust the hot air inside the equipment, and at the same time draw in the fresh air from outside, thus realizing the purpose of ventilation and heat dissipation.

4. Noise reduction: DC fan will produce a certain amount of noise during operation, but through the optimization of the design and the use of advanced noise reduction technology, can effectively reduce the noise of the fan, improve the comfort of the use of equipment.

In short, DC fans are widely used in electronic equipment, which can effectively realize the functions of heat dissipation, air filtration and purification, ventilation and heat dissipation and noise reduction, and improve the service life of the equipment and user experience. With the continuous development of technology, the performance and application areas of DC fans will continue to expand and innovate.
