DC Fans: G4020H05B-RSR-CC Application Field and Working Principle

DC Fans, whose full name is direct current fans, are widely used in today’s market. G4020H05B-RSR-CC is one of the most popular DC fans. This article will introduce its application field and working principle.

Application Field

G4020H05B-RSR-CC fans are popular in both commercial and household applications. Generally, they come with a selection of flow-rate , audible noise , static pressure and electronic speed control features. Its application field is mainly used in cooling computer and electronic products like computers, routers, switches and power supplies. As it works stably and quietly, it is suitable for audio, communication and video with strict requirements on noise.

Working Principle

The G4020H05B-RSR-CC model utilizes a three-phase drive approach through the use of its three-wire connection. It consists of six main components, a stator, a rotor,a drive motor, a fan blade, heat sink, and a thermostat.The magnet rotor revolving around the stator in the stator-magnet rotor assembly creates a rotating magnetic field in the three-phase motor, thus driving the fan blades.The fan blades then tilt and move in large circles which generate air flow. The fan motor is also connected to a controller, which is responsible for monitoring the current, RPM, and voltage of the device. The thermostat is responsible for detecting the temperature of the air passing through the fan and adjusting the fan speed accordingly in order to maintain an optimal temperature level. Finally, the heat sink is used to dissipate heat from the motor and provide cooling to the fan.

Conclusion

G4020H05B-RSR-CC DC fans are widely used for cooling computers, routers, switches and power supplies in both commercial and household applications. They have great flow-rate, audible noise, static pressure and electronic speed control features. This fan model utilizes a three-phase drive approach through the use of its three-wire connection and consists of six main components: a stator, a rotor,a drive motor, a fan blade, heat sink, and a thermostat.
