Abstract

A condenser includes a fluid inlet in an upper manifold and a fluid outlet in a lower manifold. The condenser includes multiport tubes provided with a plurality of separate flow channels which are delimited by outer opposite side walls and internal intermediate walls extending between the outer opposite side walls of the tubes. The multiport tubes define a channel space between them. A plurality of cooling plates extend between the upper manifold and the lower manifold. The cooling plates are in thermal contact with the multiport tubes to receive a heat load from fluid in the flow channels. The cooling plates have outer edges which protrude out from the channel space and are directed away from the channel space.
