ABSTRACT:
An axial-flow fan-blade, with at least one profiled guide fin extending from the surface of each blade of the fan-blade, is able to control flow direction of the fluid and keep fluid flow speed stable; and, furthermore, offsets the centrifugal force (which is caused by rotation of the blade) with the centripetal force that is generated by pressure difference of the fluid flowing across both sides of each profiled guide fin. The fan blade minimizes turbulent flow, reduces noise generated by vibration of the blades, and increases rigidity of the blades.
