Brief introduction to frameless DC fan

Frameless DC fan is the fluid that frameless DC fan through the fan impeller twice, the fluid flows in the radial direction and then frameless DC fan out in the radial direction. The intake and exhaust directions are in the same plane, and the exhaust body is evenly distributed along the width of the fan. Because of frameless DC fans’ simple structure, small size, and high dynamic pressure coefficient, they can reach a long distance. Frameless DC fan is widely used in laser instruments, air conditioners, air curtain equipment, dryers, hairdryers, household appliances, and grain combine harvesters.

What is the structure of a frameless DC fan?

The frameless DC fan is mainly composed of three parts: impeller, air duct, and motor.

The impeller material is generally aluminum alloy or engineering plastics. The aluminum alloy impeller has high strength, lightweight, high-temperature resistance, and can maintain stable operation without deformation; the plastic impeller is injection molded from a mold and then welded by ultrasonic waves. It is generally used in applications with low speed and has a larger diameter.

The air duct is generally formed by stamping and forming of thin metal plates, and can also be cast in plastic or aluminum alloy. The casing adopts a streamlined design, which can effectively reduce the loss of airflow and greatly improve the working efficiency of the fan.

The motor is the power part of the cross-flow fan, which can be powered by AC or DC. AC power supply mainly includes shaded pole motors and capacitor starter motors, while DC power supply is DC brushless motors. The drive motor and the impeller are generally installed flexibly and fixed on the air duct.

 

What is the purpose of a frameless DC fan?

1.Cooling and heat dissipation: electronic equipment, dry-type transformers, photocopiers, projectors, computers, etc.;

2.Ventilation: rooms, public places, vehicles;

3.Industrial machinery: constant temperature and drying machinery; cold and warm room equipment;

4.Household appliances: refrigeration and display cabinets, air-conditioning fans (air conditioning fans, building fans, tower fans), heaters, electric fireplaces, air curtains, built-in ovens, etc.

 

It is the responsibility of each manufacturer to produce a frameless DC fan that meets the standards, so as to ensure the safety of the electricity supply and the healthy development of the cable market. Frameless DC fan conducts many tests on frameless DC fan before they leave the factory, and the quality qualification rate is guaranteed.
