ABSTRACT:
An axial flow fan includes a plurality of auxiliary blades disposed upon and projecting from the suction and/or pressure surfaces of primary fan blades radially disposed on a hub member. The auxiliary blades extend substantially in the width direction or transversely of the primary blades, and the leading edges of the auxiliary blades, as viewed in the rotational axis direction of the fan, are disposed closer to the rotational center of the hub member than the trailing edges of the auxiliary blades. In this manner, the axial flow fan produces an axial fluid flow by means of the primary blades and a radial fluid flow by means of the auxiliary blades.
