A heat exchanger including at least one collecting tank for input and output of a first heat transfer medium, a plurality of plastic tubes receiving the first heat transfer medium from the at least one collecting tank and outputting the first heat transfer medium to the at least one collecting tank, and a plurality of metal heat exchange elements between the tubes and in heat exchange contact with the tubes and a second heat transfer medium. At least some of the heat exchange elements are incorporated in the tube walls, with wave crests and troughs embedded in furrows of the walls. The heat exchanger is manufactured by heating the heat exchange element to plasticize the tubes at least at the contact sites between the tubes and the heat exchange elements, and then producing intimate contact between the tube and the heat exchange element.
