Abstract
A reverse flow cooled dynamoelectric machine is provided with duplex gas coolers disposed in a side-by-side relationship. The coolers are baffled such that a portion of the gas flowing through both coolers is channeled to both the end portion of the rotor and to the stator and the body portion of the rotor so that both areas may be effectively cooled under reduced load operating conditions in the event of the failure of one of the coolers. In a preferred embodiment of the invention, first and second U-shaped baffles are disposed between the coolers and the inner walls of a removable dome, and a planar baffle engages adjacent free ends of the U-shaped baffles. The baffle components are dimensioned to ensure satisfactory flow of cooling gas to the body portion of the rotor. Aligned stator and rotor baffles are provided to segregate inlet zones and outlet zones in the gap between the stator and the rotor to better ensure effective cooling of the body portion of the rotor.
