Title:
SPACEBLOCK DEFLECTOR FOR INCREASED ELECTRIC GENERATOR ENDWINDING COOLING
Document Type and Number:
WIPO Patent Application WO2002050982
Kind Code:
A3
Abstract:
A gas cooled dynamoelectric machine is provided that is comprised of a rotor 10, a rotor winding comprising axially extending coils (22) and concentric endwindings (28), and a plurality of spaceblocks (140), (240) located between adjacent endwindings thereby to define a plurality of cavities (142), (242), each bounded by adjacent spaceblocks (140), (240) and adjacent endwindings (28). To enhance the heat transfer rate from the copper end turns of the filed endwinding region, at least one flow deflector structure (144), (244) is provided on a cavity facing surface (146), (246) of at least one spaceblock (140), (240) for intercepting and redirecting circulating coolant flow towards a central region of the respective cavity 1429, (242).
