    摘要: 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.

    摘要: A cast assembly for a gas turbine engine compressor 12, including a plurality of axial flow stators and a rotor having a plurality of axial flow blades 34, each of the blades having a tip section 44 and a leading edge 50. The assembly comprises a stator outer platform 70, a boss 90, a passage 92, a blade outer shroud 46 and a circumferential slot 106. A boss 90 is formed in the platform 70 and includes a passage 92. The passage 92 includes an inlet 74 and an outlet 96. The inlet 94 is disposed in the circumferential slot 106. The outlet 94 is disposed upstream of the leading edge 50 of the blades 34. The passage 92 circumferentially converges inward from the inlet 94 to the outlet 96. The outer shroud 46 joins with said outer platform 70 during the assembly of the compressor such that the circumferential slot 106 is formed downstream and proximate to the leading edge 50 of the blades 34. The circumferential slot 106 is in flow communication with the inlet 94 and converges axially

    摘要: An axial fan is disclosed that includes a hub (10) supported for rotation around the longitudinal axis of the fan, a plurality of impeller blades (12) attached to the hub (16) and extending radially from the axis of rotation, a shroud assembly (34) including a band (36) encircling the blades (12) and spaced from the tips of the blades (12) a sufficient distance to provide ample clearance to avoid contact between the blades (12) and the band (36) during shipment and operation of the fan, the shroud (34) further including an orifice (38) positioned upstream of the blades (12) for preventing air from flowing between the orifice (38) and the band (36), the orifice (38) having a downstream end located adjacent to but spaced from the impeller blades (12) and having a diameter such that the impeller blades (12) extend outwardly from the hub (10) beyond the orifice (38) so that the flow of air over the tips of the impeller blades (12) is substantially reduced, which increases the efficiency of the fan.

    摘要: A fan shroud 4 is positioned upstream of a heat exchanger 5. An intake portion 9 of the fan shroud 4 has the shape that the axial length a thereof is smaller than a radial length b thereof, so that the intake portion expands quickly and the air flowing inwardly toward the fan blade is well guided by the intake portion.

    摘要: Ein Axialgebläse mit einem sich konisch verengenden Einlaufteil (2) und einem sich daran anschließenden zylindrischen Gehäuseteil (3) , in dem ein Laufrad (4) drehbar angeordnet ist, ist mit einer Einrichtung zur Stabilisierung der Abreißgrenze versehen. Diese Einrich­tung besteht aus einem feststehenden Leitring (6) , der dem Laufrad (4) vorgeschaltet ist. Der Leitring (6) weist etwa den gleichen Durchmesser auf wie der zylindrische Gehäuseteil (3) und ist von einem Ringkanal (7) umgeben. Dabei weist der Leitring (6) von den beiden Enden des Ringkanals (7) etwa den gleichen Abstand auf. Innerhalb des Ringkanals (7) sind gegen dessen Achse angestellte Lenkschaufeln (10) angeordnet, deren Anström- und Ab­strömkanten schräg nach außen verlaufen und aus ebenen Blechen bestehen.
