Patent ID: 7798204

Claim:
A centrifugal condenser for use in an engine that produces exhaust steam, said centrifugal condenser comprising: a stacked arrangement of metal plates forming a vertical wall structure having an outboard side and an inner side surrounding an open central core, and said plates being structured and arranged to include outer top and bottom surfaces facing outer radial gaps that are open to said outboard side, and said plates further including inner top and bottom surfaces facing inner radial gaps that are open towards said central core; an air duct surrounding said outboard side of said vertical wall structure of said stacked arrangement of metal plates; at least one intake blower structured and disposed for intake and forced distribution of ambient cooling air through said air duct, into said outer radial gaps and across the outer top and bottom surfaces of said plates for cooling said plates; a rotatable impeller within said central core for driving the exhaust steam into the inner radial gaps and against the inner top and bottom surfaces of said plates to cause the steam to condense into a liquid; and at least one passage formed in said stacked arrangement of metal plates for directing the condensed liquid to a collection reservoir.
