DC fans, sometimes referred to as direct current fans, are small electrical fans that expend power when they rotate. Its operating voltage and current are DC signals, which can be powered by any DC voltage available. OD9220-12HS fans are one of the most commonly used DC fan models. This product has a wide application field and working principle.

Application Field

OD9220-12HS fans can be used in various fields of the industries, such as the communication industry, telecom industry, computer industry, military, medical equipment and so on. They provide better heat dissipation and cooling performance in the high speed environment, and they can be used for the cooling of electronic equipment and components.

Working Principle

The working principle of the OD9220-12HS fan is based on the principle of when the stator and rotor of the motor are energized, the rotor will rotate. When the rotor rotates, the blades on the fan will produce a fan-shaped air duct, so that the air around it will be sucked in and the air pressure is increased in the fan chamber. The fan blade is connected to the rotor and is driven to rotate. At the same time, the air pressure in the fan will be changed and the air will be blown out

The rotating speed of the fan is determined by the voltage of the DC power supply. The higher the voltage, the faster the speed. In addition, the OD9220-12HS fan is also equipped with a temperature control function. When the temperature of the CPU or other electronic components is too high, the fan will automatically accelerate its rotation and speed to reduce the temperature.

Conclusion

In a nutshell, the OD9220-12HS fan has a wide range of application fields and works according to its well-known working principle. It can provide high cooling efficiency, improved life, safe temperature control and high device cooling performance in the environment of high speed or high temperature.
