Abstract:
An alternator comprising:an Inner housing; an outer housing mounted over said inner housing; a pair of o-rings positioned between said inner housing and said outer housing thereby creating a sealed flow chamber therebetween; said flow chamber including a first flow channel, a second flow channel and an axial passageway interconnecting said first and second flow channels; said first flow channel being defined by opposing first and second disk shaped portions of said inner housing, such that said first flow channel is a disk shaped cavity extending diametrically across said alternator; said second flow channel being defined by an inner diameter of said outer housing and an outer diameter of said inner housing, such that said second flow channel forms an annular jacket extending entirely around said alternator; said axial passageway being defined by an arcuate notch formed within said first disk shaped portion of said inner housing such that coolant is directed axially from said first flow channel into said second flow channel through said axial passageway; an inlet extending from said first flow channel to allow coolant to enter said first flow channel, said inlet being positioned diametrically across from said axial passageway such that coolant entering said inlet must flow diametrically across said alternator to reach said axial passageway; an outlet extending from said second flow channel to allow coolant to exit said flow chamber, said outlet being positioned diametrically across from said axial passageway such that coolant entering said second flow channel must travel annularly around said alternator to reach said outlet.
