Definitions

  • the invention relates to a mechanically joined heat exchanger, in particular for motor vehicles according to the preamble of claim 1.
  • Heat exchangers especially those for motor vehicles are today mainly made of aluminum or an aluminum alloy, wherein this particular for the heat exchanger network consisting of pipes and ribs applies. Other parts of the heat exchanger that are not directly at the Heat transfer were, for cost reasons made of plastic made, such. B. from EP-B 962 739 known.
  • the tube / rib block is - depending on the requirements of the heat exchanger performance - either soldered or mechanically joined.
  • For mechanically joined heat exchangers becomes the connection of the tubes with the ribs as well as with a tubesheet of the collecting tank achieved by mechanical expansion of the tubes. Because of the increased requirement for tightness, the tube bottom connection after expansion for certain applications (see EP-B 962 739) additionally by sealing means from the outside, z. B.
  • Heat exchanger has a collecting box, the exclusively of aluminum parts or parts of an aluminum alloy which mechanically joined, d. H. held together by a clip connection become.
  • the tubes of the tube / rib block are end in Widening of the floor widened, d. H. mechanically with the collecting box connected.
