External rotor axial fan

The external rotor axial flow fan has the characteristics of compact structure, convenient installation, reliable operation, low noise, energy saving and high efficiency. Products are widely used in hotels, restaurants, industrial and mining enterprises, office buildings, theaters and other building facilities, as a refrigerator freezer supporting equipment or ventilation and heat dissipation. (for example, refrigerators, ice making machines, cold air blower, cold water machine, condensing unit and other refrigerating equipment or facilities for supermarket, with dehumidifier, evaporator, side wall fan, fire fan, central air conditioner fan and other equipment).

Extension structure:

The external rotor axial flow fan consists of fan blades, external rotor motor, mesh hood and lead wire. The structure of the fan is calculated by the finite element method. The strength check, modal analysis and harmonic response analysis are used to ensure that the product has the advantages of stable and reliable structure, high safety factor, small vibration and strong anti-interference ability. According to customer requirements, we can install heat protector, connection box and other components, or choose cylinder type, Fang Kuang. Different types of installation. The blade is designed according to the principle of aerodynamic law, acoustic principle and acoustic performance. The blade is twisted from the top to the root of the leaf according to a certain rule. The material is made of high quality steel sheet or plastic. Through dynamic balance check, the starting performance is good, the operation is smooth and the noise is low.
