"Cross Flow Fan" is mainly composed of the impeller, air duct and the motor of three parts. Impeller material is generally aluminum or plastic. High-strength aluminum alloy wheel, light weight, high temperature, able to maintain long-term stable operation without deformation; plastic impeller from the injection mold, and then an ultrasonic welded together, generally used for low speed situations, larger diameter. Duct generally sheet metal stamping, plastic or aluminum can also be cast. Streamlined chassis design, can effectively reduce the loss of air flow, so that the efficiency of the fan is greatly improved. Motor is "Cross Flow Fan" power section, AC power supply can be a DC power supply. AC powered mainly shaded pole motor and capacitor start motor, a DC power supply, compared with brushless DC motor. "Cross Flow Fan" and the impeller drive motor is generally flexible installation, fixed to the duct.
