DC fan also known as DC ventilation fan, is a common cooling fan commonly seen in general electronic equipment. DC fans commonly used are based on 9GA0812H1611. This type of fan is widely used and has a simple working principle.

Features and Applications

The 9GA0812H1611 DC fan is a single phase DC fan that is rated for 12VDC. This type of fan runs quietly with noise less than 32 dB and provides users with superior air performance. This fan is RoHS compliant, and its housing is made of plastic ABS with good anti-corrosion, heat resistance and durability.

This DC fan is widely used in all kinds of electronic equipment for heat dissipation or ventilation purposes such as power supply, communications device, computer, monitoring system, etc. due to its small size, quiet operation, work efficiency, environmental performance and cost-effectiveness.

Working Principle

The 9GA0812H1611 DC fan is driven by a DC motor. Its working principle is fairly simple. A basic DC motor consists of a current carrying coil mounted on an axle and surrounded by a permanent magnet. When electricity is connected to the motor, current flows through the coil creating a magnetic field. This field interacts with the magnet on the outside and causes the coil and the axle to spin.

The spinning of the axle is used to turn the fan blade, creating air flow in the desired direction. The speed of the fan rotation is directly related to the strength of the electric current. More current means faster rotation and greater air flow. This is why a DC fan allows for speed control; by regulating the strength of the current the fan can be made to run faster or slower.

Conclusion

The 9GA0812H1611 DC fan has a wide range of applications due to its small size, quiet operation, efficiency and good environmental performance. All of these features make the DC fan a great choice for the cooling and ventilation applications. The working principle of a DC fan is relatively straightforward too, as it has a simple design and requires only minimal current to produce airflow.
