DC Fans are electrical machines which can be used in many types of applications, ranging from fans to drive air through manufacturing and industrial buildings, to the cooling of computers and electronics. The QFR1248GHE DC fan is a versatile and reliable fan option for several applications. This article examines the different application fields and working principles of this fan.

Application Fields:

The QFR1248GHE fan is a radial flow fan and can be used in a variety of applications in many different industries. It is primarily used for cooling in commercial and consumer electronic devices such as computers, laptop computers, cell phones, televisions and digital cameras. This fan is also suitable for use in industrial process control and electronics applications such as air flow sensing, smoke extraction, dust collection, and cooling of food refrigeration systems. The QFR1248GHE fan is also often used as a cooling fan in audio and video production equipment.

Working Principle:

The QFR1248GHE DC fan consists of a motor, fan blade, and a control board. The motor consists of a rotor and stator. The rotor is a set of electromagnet coils, which when energized by electricity, create an electromagnetic field. When this field is passed through the stator, the rotor and fan blade begin to spin. The fan blade is attached to the rotor so that it will spin at the same speed. The control board regulates the flow of electricity to the motor. When the motor is turned on, the control board applies power to the motor, which in turn causes the fan blade to spin.

The fan blade is designed to move air in a circular motion, creating an airflow that cools the components inside the device. The motor and fan blade can be adjusted to control the speed and direction of the airflow. When the speed is increased, the airflow increases, providing more cooling for the components. The direction can also be adjusted to create air flows in different directions.

The QFR1248GHE is a 250mm x 189mm DC fan with a design that is both quiet and durable. It features durable brushless motor technology that provides efficient operation and a long-lasting service life. It has a wide range of speed control, with a maximum speed of 2450 RPM, and features a low-noise level of 28dBA.

In conclusion, the QFR1248GHE DC fan is a versatile and reliable fan for many industrial and consumer applications. It is designed to move air in a circular motion, providing efficient cooling. The control board can be adjusted to control the speed and direction of the airflow, making it an ideal choice for many different uses.
