The ends of the flat pipes are connected to corresponding openings in the base of junction boxes consisting of solder-plated material and are soldered to the junction boxes, wherein the flat pipes likewise consist of a soler-plated material and the ends have a round cross section, and a section with radial press-fit is present at the ends of the flat pipes in the region of the base of the junction boxes. The flat pipes consist preferably of material solder-plated on both sides, and supporting webs are situated in the flat pipes and are connected to the flat pipes by means of the solder of the flat pipes.
