  • the invention relates to a heat exchanger according to the preamble of claim 1 and a method for producing a heat exchanger according to the preamble of claim 9. Furthermore, the invention relates to an automotive air conditioning system and a motor vehicle.
  • Heat exchangers serve 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 particularly useful in motor vehicles, in which the heat exchanger is used to deliver the heat released from the engine waste heat to the ambient air.
  • the heat exchanger generally consists of two manifolds between which a plurality of tubes are arranged.
  • heat exchangers can be used in motor vehicles, for example, engine or transmission oil, air, z.

  • the heat exchanger components are generally flat tubes, discs with and without breakthroughs and two connecting pieces, on which an inlet or an outlet opening for the fluid is formed.
  • turbulence inserts are generally arranged and the ends of the flat tubes are each closed by means of an insert.
  • recesses are arranged on a flat tube.
  • the discs with breakthroughs are placed in each case in the region of the end.
  • the recesses of the flat tubes come into coincidence with the openings of the discs.
  • the flat tube consists of a cover and bottom wall, in each of which the recess is arranged in the region of the ends. Between the cover and bottom wall, the fluid can flow into the flat tube. From the collecting tube, which is formed by the recesses and the openings, the fluid flows into the flat tubes.
  • the disks assume different functions.

  • a type of heat exchanger component ie a disk, have different functions.
  • the individual discs are each placed on the flat tubes. This can lead to errors if the wrong discs, d. H. with a wrong function, be placed in the wrong position inside the heat exchanger. This leads to considerable damage, because the heat exchanger is generally no longer suitable for normal use, if the error is not detected, or when detecting the incorrect placement of the discs during manufacture, especially during the arrangement of the discs and the flat tubes on top of each other , a part of the already established heat exchanger must be dismantled again in a costly and expensive manner.
  • the EP 0 961 095 B1 shows a generic heat exchanger.

  • the heat exchanger components of the same type with the different outer contour have different functions or properties.
  • the discs are formed with or without openings. Washers with apertures serve to form a manifold within the heat exchanger due to the arrangement of discs with breakthrough on top of each other. Discs without apertures are generally arranged at the top and bottom of the heat exchanger to complete the collection of the discs with breakthrough and recesses in pipes, in particular flat tubes.
  • the different outer contour is formed by means of at least one projection and / or at least one recess.
  • the at least one projection and / or the at least one recess is rectangular in cross section.

  • optical, electrical or magnetic the surface or geometry, ie the outer contour of the heat exchanger components detect or scan. The location of a heat exchanger component is thus determined by the blueprint of the heat exchanger component.

  • the individual heat exchanger components are arranged to form a structural unit. This is generally done by superimposing the individual heat exchanger components in a block paver on a table. After assembling the individual heat exchanger components to form a structural unit, they are compressed by a clamping device under prestress. The individual heat exchanger components are provided on the surface with a solder, d. H. are plated with solder. The preloaded assembly is then heated in a soldering oven to temperatures in the range of about 600 ° C. As a result, the individual heat exchanger components are soldered together, so that they are fluid-tightly interconnected. As a fluid, for example, a cooling liquid or air is used.
