DC Fans

A DC fan is a type of fan powered by direct current. Generally, DC fans can be divided into two types, one with a rotor and one without. The former motor-driven DC fan, codenamed 4312/2, is the most widely used fan in industry, while the latter is widely used in notebook computers for cooling.

4312/2 Application Field and Working Principle

The 4312/2 motor-driven DC fan is most commonly used in computer cabinets, industrial applications such as servers and automation projects. It utilizes direct current (DC) electricity to power the fan motor and can generate a considerable amount of airflow with relatively low power consumption.

The working principle of the 4312/2 DC fan is simple: a brushless DC motor is used for power transmission, and the rotor is usually composed of several small permanent magnets. A current is then passed through the motor and the rotor is attracted to the stator, which has a different polarity. This attraction causes the rotor to rotate, generating a current of air.

The more power supplied to the motor, the faster the rotor spins, and the higher the airflow it generates. Generally speaking, the fan motor speed can be changed freely through adjusting the DC power supply voltage, so as to achieve the effect of regulating air volume. This makes the 4312/2 DC fan an ideal equipment for external cooling system.

Features

The 4312/2 DC fan is characterized by its small size, light weight and relatively low power consumption. And it has high operating efficiency; the air volume is large and the air pressure is also strong, and its life span is relatively long. It can quickly reduce the temperature of the ambient environment in a confined space, improving the thermal performance of the computer cabinet.

In addition, the 4312/2 DC fan has some other advantages, such as low noise, low vibration and high reliability; the noise and vibration can be reduced by changing the rotating speed of the fan motor; and the high reliability can be achieved through the high insulation resistance of the brushless fan motor.

Conclusion

The 4312/2 motor-driven DC fan is one of the most widely used fans due to its small size, light weight and low power consumption, and its ability to quickly reduce the temperature of a confined space. In addition, its low noise, low vibration and high reliability make it the ideal fan for industrial applications such as computer cabinets and servers.
