9GV1224H101

DC fans are fans primarily used in computer systems to keep internal parts cool and running smoothly. They are the most popular type of cooling fan available in a wide range of sizes for various configurations of PC cases. The 9GV1224H101 is a standard type of DC fan with a 12 volt rating and is used in a variety of applications.

Applications

The 9GV1224H101 is a standard size DC fan that is used in a variety of applications. It is widely used in desktops, tower PCs, as well as laptop computers, servers, routers, kiosks, POS systems, and more. In addition, it is used in industrial applications such as automated process control, medical devices, cooling of electronic enclosures, and other precision instrumentation.

Working Principle

DC fans are powered by direct current (DC) electricity. The 9GV1224H101 uses a four-wire connection to regulate fan speed. Two of the four wires supply power to the fan while the other two control the voltage sent to the fan, allowing it to operate at different speeds. Typically, voltage changes are accomplished using a Pulse-Width Modulation (PWM) signal. This PWM signal is controlled by the embedded system, such as the motherboard, and can be adjusted to deliver power to the fan in varying intensity pulses, allowing for more intricate control of the fan speed.

The 9GV1224H101 also uses internal semi-conductors to convert the DC power from the power supply to AC power, which then runs through an internal winding. This winding provides the magnetic field necessary to turn the motor shaft, thus spinning the fan blades. The spinning blades then draw in air from the side of the fan and discharge it from the center. This is what produces the cooling effect of the fan.

Conclusion

The 9GV1224H101 is a standard DC fan that is used for a wide variety of applications and systems. It is powered by DC electricity and uses a four-wire connection to regulate fan speed, allowing for more intricate control of the fan speed. Internally, it uses semi-conductors to convert the DC power to AC power and then spins the blades to draw in air from the side and discharge it from the center, thus producing a cooling effect.
