Publication number: 20110139424Abstract: A heat exchanger, especially a heat exchanger for a motor vehicle, is provided that includes a plurality of tubes, at least one collecting tube with a wall and openings in the wall, supports protruding from the wall in the axial direction of the openings being formed at the openings. Wherein the tubes in the region of one end of the tubes are disposed partly at the supports and a fluid-tight connection exists between the supports and the tubes, so that a fluid can be passed through the tubes and the at least one collecting tube, and at least one inlet opening for passing the fluid in and at least one outlet opening for passing the fluid out. The mechanicals stability between the tubes and the at least one collecting tube is to be improved. This objective is accomplished owing to the fact that the thickness of the supports is less than the thickness of the wall, especially in the region of the openings of the collecting tube.Type: ApplicationFiled: December 10, 2010Publication date: June 16, 2011Inventors: Thomas Bensel, Hicham Rouhana, Haymo Broeder
