ABSTRACT:
A fan module with an axial flow fan and a shroud member. The axial flow fan has a hub and a plurality of fan blades, each blade extending radially from the hub. At the tips of the blades are air guide members secured to respective fan blades and concentric with the hub. Each air guide member has an axially-extending arcuate portion, and a respective lip portion extending radially outwardly from each said arcuate portion. The axially-extending portion has an axial length substantially equal to or less than the axial length of said hub. The shroud member has a surface cooperating with the air guide members in an arrangement to reduce tip vortices.
