Abstract:

An automotive alternator includes an inner housing assembly, an outer housing assembly mounted over the inner housing assembly, and an internal plate mounted within the outer housing assembly. The inner housing assembly, the outer housing assembly, and the internal plate define a sealed flow chamber. The flow chamber includes an inlet reservoir and an outlet reservoir located adjacent a first end, and a cross over reservoir located adjacent a second end. The inner housing assembly includes a plurality of radially extending axial fins. The fins extend outward from the sleeve toward the outer housing to define a plurality of axial flow channels. A first portion of the flow channels interconnects the inlet reservoir to the cross over reservoir and a second portion of the flow channels interconnects the cross over reservoir to the outlet reservoir.
