ABSTRACT:
A baffle for improving coolant gas flow distribution in the gap region of a gas cooled dynamoelectric comprises a perforate member defining at least one gas flow path therethrough. The baffle preferably is spaced from the arcuately surrounds the rotor of the generator, wherein the gas flow path provides communication between the end space region and gap region of the generator. The member may define a plurality of gas flow paths disposed in a predetermined array. Gas exiting the gas flow paths may be directed from substantially parallel to the axis of rotation of the generator to an outwardly radial angle of about 30.degree. with respect to the axis of rotation. The size, spacing and disposition of the gas flow paths are coordinated with circumferential gas flow paths around the baffle to provide rapidly radially diffused coolant gas flow downstream the baffle, thus ensuring adequate coolant gas flow to stator core coolant ducts of the generator.
