Abstract
An axial flow air impeller for automotive radiator and heat exchanger use comprising a hub, a plurality of air moving blades and an orifice ring, the hub adapted for rotation about an axis and carrying a plurality of integrally formed similar circumaxially spaced and generally radially outwardly projecting air moving blades, each of said blades having a root end portion integral with the hub and a radially outwardly disposed tip end portion with smoothly curving side edges therebetween, said air impeller being adapted for unidirectional rotation and said side edges comprising leading and trailing edges the leading edge of which curves substantially forwardly when viewed from root end portion to tip end portion, the projected width of each blade thus being at least 40% greater at the tip end portion than at the root end portion, the maximum thickness of each blade varying from a maximum at the root end portion to a minimum at the tip end portion, and the maximum thickness at the tip end portion being at least three times the thickness at the blade trailing edge, and an orifice ring integral with each blade tip end portion and circumscribing the plurality of blades, said ring having upstream and downstream ends and having a flange at one end with a substantially smooth radius at the junction with the ring portion.
