Liquid cooled alternator having finned stator sleeve

A coolant system for an internal combustion engine for an automobile comprising:

• an engine having flow passages therein adapted to allow coolant to flow through said engine;
• a radiator adapted to cool the coolant flowing therethrough;
• a heater core adapted to receive heated coolant which has passed through the engine and to provide heated air to a passenger compartment of the automobile;
• an alternator having flow passages therein adapted to allow coolant to flow through said alternator, said alternator being positioned up-stream of said heater core such that heat transferred from said alternator to said coolant is utilized by said heater core to provide heated air to a passenger compartment of the automobile;
• said alternator having and an inner housing, an outer housing mounted over said inner housing, and an internal plate mounted within said outer housing, said inner housing, said outer housing and said internal plate defining a sealed flow chamber;
• said flow chamber including an inlet reservoir and an outlet reservoir located adjacent a first end of said alternator, and a cross over reservoir located adjacent a second end of said alternator;
• said inner housing including a plurality of radially extending axial fins, said fins extending radially outward toward an inner surface of said outer housing to define a plurality of axial flow channels;
• a first portion of said plurality of axial flow channels interconnecting said inlet reservoir to said cross over reservoir and a second portion of said plurality of axial flow channels interconnecting said cross over reservoir to said outlet reservoir.
