Abstract:
A shroud for an axial-flow fan includes an annular barrel. The barrel includes a cylindrical segment and a conical segment downstream of the cylindrical segment. The conical segment is angled radially inwardly from the cylindrical segment at an angle of between 15 and 35 degrees. The shroud also includes an annular outlet bell coupled to the conical segment at an apex defining a transition between the conical segment and the outlet bell. The outlet bell and barrel contain a plurality of leakage stators. A stator pedestal extends from a radially-inner surface of the outlet bell to a stator pedestal tip, and a depth (a) of the outlet bell measured from an end surface of the outlet bell to the apex is less than one-half a depth (b) measured from the end surface of the outlet bell to the stator tip in the direction of axial airflow through the fan shroud.

Claim (Index 4):
The fan shroud of  claim 3 , wherein each stator pedestal includes a radially-outer surface that forms an angle with the cylindrical segment of between 15 degrees and 35 degrees.
