摘要:
The air moving device includes a rotor and a stator. The quantity of the rotor blades is not less than 5 and not greater than 12. The average blade angle of rotor blades is not less than 45 degrees and is not greater than 64 degrees. The ratio of the hub diameter to the rotor diameter is not less than 0.4 and not greater than 0.79. The quantity of the stator blades is not less than 6 and not greater than 23. The average blade angle of stator blades is not less than 45 degrees and not greater than 70 degrees. The ratio of the total thickness of the air moving device to the rotor diameter is not less than 0.76 and not greater than 1.7. The ratio of the stator axial thickness to the rotor axial thickness is not less than 0.28 and not greater than 0.65.
