ABSTRACT:
A heat exchanger member contoured to fit along one side of an exhaust pipe is retained in place on the exhaust pipe by clamps. In one form of the invention the exhaust pipe forms a part of the heat exchanger reservoir in which case leak preventive adhesive secures the heat exchanger member to the pipe. The heat exchanger member is provided with intake and discharge tubes, the intake tube connected to the pump of an existing windshield washer assembly and discharge tube being connected, through a manifold to the discharge nozzles adjacent to the windshield. In another form of the invention, the discharge from the heat exchanger is directed along a header or manifold of a nozzle assembly adjacent to and for washing the rear window of the automobile. In still another form of the invention, the heat exchanger forms an essentially closed reservoir so that the exhaust pipe does not come in contact with the fluid flowing therethrough. The process includes heating the windshield cleaning liquid by heat from the exhaust of an engine and then discharging the same in a heated condition onto the windshield or window of an automobile.
