Abstract

A heat exchanger includes a tube with a heat-exchange passage and an end piece. The heat-exchange passage directs the flow of a first medium and includes a first flow section and a second flow section arranged in parallel. The end piece has a tube plate that includes a base plate, a diverter plate, and a cover plate. An end of the tube connects to the base plate. The diverter plate has a cutout that forms a diverter passage. The cover plate lies adjacent to the diverter plate and covers the diverter passage in a fluid-tight manner. A second medium flows exterior to the heat-exchange passage.
