A fan module, particularly for cooling motor vehicle engines allows for improved cooling of the fan motor. The fan housing () in which the fan motor () is arranged has fixed air-channeling elements () which are arranged in the region of a fan hub () of the fan wheel () driven by the fan motor () and which only partially cover an outlet cross section () defined by the fan housing ().

Fan module

A fanhas a hub, a plurality of fan bladesattached to the hub at one end and extending outwardly from the hub, and a ringconcentric with the hub and coupled to tipsof the blades. Wherein a dimensionless radius (r/R) is defined from a center of the hub (r/R=0) radially outwardly, wherein each tip of the blades is r/R=1. A stagger angle is defined as an angle between an axis of rotation of the fan and a set angle of each fan blade, and C/R is a dimensionless chord length where C is chord. The fan is defined by values of r/R, C/R and stagger angle.

Low pressure fan with high-flow

A fanincludes a central hub, an outer ring structure, and a plurality of fan blades. Each blade is of generally Y-shaped configuration having first and second separate branches, respectively, coupled to the huband merging with a third branch. The third branchis coupled to the ring structureat a tipof the blade

Low pressure fan with Y-shaped blades

A fanincludes a hub, a plurality of fan bladesattached to the hub at one end and extending outwardly from the hub, and a ringconcentric with the hub and coupled to tipsof the blades. A dimensionless radius (r/R) is defined from a center of the hub (r/R=0) radially outwardly, wherein each tip of the blades is r/R=1. A pitch ratio increases up to about r/R=0.85, and decreases in a range of about 0.85&#x3c;r/R&#x3c;1.0. In the range of about 0.6&#x3c;r/R&#x3c;1.0, a chord length decreases continually.
