Abstract
A cooling fan assembly for cooling a heat exchanger includes a shroud having a plurality of stators extending radially to support a hub. A flow-guide including an outer rim and inner rim surrounds the shroud and extends to the heat exchanger. The outer rim extends from the heat exchanger to the stators. The inner rim extends annularly about the axis and curves convexly from the outer rim. A fan unit includes a plurality of fan blades extending radially from a motor supported by the hub. Each fan blade includes a leading edge facing the stators and a trailing edge facing in the opposite direction with a blade tip extending therebetween. A fan section extends from the inner rim and axially about the fan blades. The stators are disposed between the heat exchanger and the fan blades. The stators have a front edge facing the heat exchanger and a back edge facing the fan blades. Each stator is connected to the inner rim with the front edge extending radially outward and farther than the back edge.
