Definitions

  • the invention relates to a heat exchanger according to the preamble of claims 1 and 10 and a method for producing a heat exchanger according to the preamble of claim 6. Furthermore, the invention relates to a motor vehicle air conditioning.
  • Heat exchangers are used to transfer heat from one fluid to another fluid. For example, heat is transferred from a heat exchanger to the ambient air by a heat exchanger. This is used in particular in motor vehicles, in which the heat exchanger serves to deliver the exhaust heat released by the internal combustion engine to the ambient air.
  • the heat exchanger generally consists of two manifolds, between which a plurality of tubes is arranged. In the headers openings are introduced, in which the pipes open. The tubes are fluid-tightly connected to the openings of the headers.
  • the openings in the headers are made by punching or piercing. When punching through a wall of the manifold, the opening is punched through, so that that portion of the wall, which forms the later opening, is removed.
  • the bearing surface of the tubes in the openings of the collecting tubes thus corresponds to the thickness of the wall of the collecting tube in the region of the opening.
  • When piercing the openings through the wall of the collecting tube forms an annular passage at the openings, which corresponds to the deformed wall of the collecting tube in the partial area.
  • the partial area is that area of the wall of the collecting tube which corresponds after production to the opening.
  • the passage, which corresponds to the wall of the collecting tube in the region of the openings is substantially not stretched in the piercing, but only bent. This corresponds to a cross-section z.
  • the length of the passage or the bearing surface of the tube at the opening has a significant influence on the mechanical stress on the connection between the tube and the manifold.
  • Mechanical stress on this connection results, for example, from thermal stresses due to high compressive and / or tensile forces or expansions in the tubes or the manifold, as well as bending superpositions and bends or deformations of the tubes or the manifold.
  • This can damage, especially leaks, arise at the connection between the pipe and the manifold, resulting in failure of the heat exchanger.
  • This is generally associated with high costs, because a repair of the heat exchanger is not possible and this must be replaced.
  • the leakage of the heat exchanger leads to a loss of cooling fluid, so that the drive with the motor vehicle must be interrupted.
  • EP 0 990 868 B1 shows a generic heat exchanger.
  • the thickness of the passages in which the tubes are inserted corresponds to the thickness of the wall of the collecting tube outside the openings for introducing the tubes.
  • only in a portion of the passage in the direction of an axis of the openings creates a contact between the passages and the tubes.
  • only a small bearing surface of the tube is present at the passage, so that there is only a low mechanical strength in this important connection region between the tube and the manifold.
  • a collection plate has openings into which the ends of flat tubes are inserted, which are connected by soldering to the wall of the collection plate. To facilitate this connection, each hole is surrounded by a collar.

  • the tube or the opening is in cross section, for example, circular, rectangular or square.
  • the thickness of the passages decreases from the beginning of the passages on the wall of the collecting tube to one end of the passages, preferably continuously.
  • the end of the passage can either end in the flow space of the manifold, d. H. in the same way as the end of the tube, which is arranged in the collecting tube or ends outside the collecting tube, ie. H. the end of the passage ends in the opposite direction than that end of the tube which is arranged in the collecting pipe.
