发明名称
摘要 A fan assembly for directing fluid flow in a hybrid radial and axial direction includes a backplate having an inner diameter portion and a substantially frusto-conical outer diameter portion positioned about a center axis (CL), a plurality of blades extending from the backplate, and an annular fan shroud positioned adjacent to the plurality of blades and configured for co-rotation therewith. The backplate, the plurality of fan blades and the fan shroud form a fan subassembly, and an overall depth of the fan subassembly is approximately 20-35% of an overall fan subassembly diameter (øD1).
