A fan shroud (100) for a cooling fan assembly with a fan (110) that is rotatable about an axis of rotation (116) defines a downstream direction along the axis of rotation (116). The shroud (100) includes a barrel (118) for containing the fan (110). The barrel (118) is concentric with the axis of rotation (116) and further includes a base portion (122). A plenum (130) includes a plenum body (132) extending radially from the base portion (122). The plenum body (132) defines at least one edge (134) of length LI. A skirt (140) extends proximate the at least one edge (134) of length LI and substantially parallel to the axis of rotation (116). An interface (142) joins the at least one edge (134) of length LI and the skirt (140) and has a length LI. The interface (142) comprises an underside having a transition surface (146) of a length less than length LI. |
