DC Fans are a type of cooling device that utilizes electric motors to provide cooling. The 9GA0812B20011 is a type of DC fan that incorporates a range of features to provide superior cooling power and efficiency. Its application field and working principle are explored in detail in this article.

Application Field

The 9GA0812B20011 is most suitable for cooling applications that require a high-powered, reliable fan. It is specifically designed for indoor space cooling and ventilation, as well as cooling applications for a range of electronic equipment, such as computers, servers, and networking and telecoms equipment. Its large blades provide a high-volume airflow that is effective for cooling large, confined indoor spaces.

Features

The 9GA0812B20011 is equipped with a number of features that make it a reliable, powerful cooling solution. It has a minimum speed of 800 RPM, a maximum speed of 4600 RPM, and can deliver up to 200 CFM of airflow. It also features a dual-pole motor design, which ensures optimal efficiency and silent operation, and a high-temperature resistance of up to 105 oC.

In addition, the 9GA0812B20011 is equipped with a series of built-in thermal protection and motor protection features that prevent overheating and overloading of the motor. It also offers adjustable speeds, which make it easy to customize the fan speed to the cooling needs of different environments. The fan comes with a power cord and is designed to operate on voltage ranging between 12V and 24 V DC.

Working Principle

The 9GA0812B20011 is designed to function with DC power, which means it draws power directly from a DC power source. Its dual-pole motor rotates the fan blades in a circular motion, creating an airflow. As air passes through the fan blades, it is drawn into the fan inlet, where it is cooled before exiting the fan outlet. The cooled air is then pushed out of the fan, providing cooling for the surrounding environment.

The motor’s speed is regulated by internal circuitry that adjusts the voltage sent to the motor. The fan is also regulated by a built-in thermal sensor which automatically adjusts the fan speed to maintain a safe operating temperature of up to 105 oC. This ensures optimal cooling power for longer periods of time without overheating or overloading the motor.

Conclusion

The 9GA0812B20011 is a powerful, efficient DC fan designed for cooling indoor spaces and electronic equipment. It features a range of features, such as adjustable speeds, a dual-pole motor design, and a high temperature resistance, that provide superior cooling efficiency and reliability. The fan also functions using a DC motor, which draws power directly from a DC power source. With its range of features, the 9GA0812B20011 is a reliable, powerful cooling solution.
