摘要： A generator cooling assembly is provided and includes a rotor, a generator assembly and an air-cycle machine (ACM). The generator assembly includes a generator housing, a generator housed in the generator housing and a shaft coupled to the rotor to transmit shaft power from the rotor to the generator to drive the generator. The ACM is housed in the generator housing and is receptive of air. The air is cooled by the ACM and output from the ACM to the generator as fully cooled air to cool the generator.

摘要： A turbogenerator includes a stator core defining a first end and a second end, a plurality of stator bars disposed within the stator core, each stator bar including a coolant flow path, and a parallel ring having a first segment and a second segment separate from the first segment. The parallel ring is coupled to the first end of the stator core and is arranged to electrically connect the plurality of stator bars and to fluidly connect the coolant flow paths of the plurality of stator bars. A tang includes a main chamber, a first coolant opening, a second coolant opening, and a distribution channel that fluidly interconnects the main chamber, the first coolant opening, and the second coolant opening. A first lead tube has a first lead end connected to the first coolant opening and a second lead end connected to the first segment, and a second lead tube separate from the first lead tube has a first lead end connected to the second coolant opening and a second lead end connected to the second segment. The plurality of stator bars, the parallel ring, the tang, the first lead tube, and the second lead tube cooperate to define a portion of a circuit and a portion of a cooling path.
