TURBO FAN

摘要

A turbo fan is provided to increase the amount of blown air even the axial height is small to install the turbo fan in a small space. A turbo fan includes a hub(52), a shroud(54), and a plurality of blades(56). A motor shaft is connected to the inner peripheral end of the hub to transfer power. The shroud guides sucked air from the axial direction to the radial direction. The plurality of blades blow the sucked air so that the sucked air can be discharged radially. The thickness of the outer peripheral end of the shroud is thinner than the thickness of the inner peripheral end thereof so that the outer end of the blade is higher than the height of the inner end thereof.
