Definitions

  • the invention relates to a heat exchanger, in particular for motor vehicles, its components made of flat tubes, corrugated fins, tube sheets with Openings for receiving the ends of the flat tubes and with connecting longitudinal and Crossing edges, as well as with four corners, exist, and off Collection boxes with two longitudinal walls for connection to the Connecting longitudinal edges, from side parts with caps, to the closure the lateral openings of the collecting boxes, wherein the closure caps a Have edge and wherein all parts are made of aluminum, the is suitably coated with solder, for metallic connection by means of a Soldering process.
  • This heat exchanger was registered with the DPMA on July 22, 2003 and received the file number DE 103 33 150.6.
  • the object of the invention consists in the development of this state of the Technology.
  • a heat exchanger is to be proposed, whose Manufacturability, in particular with regard to the creation of denser and stronger Soldered, further simplified or improved.
  • contour - cutout Can be further developed with a flange-like fold to the Increase connection area with the cap. This measure can be provided in particular when the sheet thickness of the tube sheet is reduced shall be.
  • a heat exchanger for motor vehicles is shown, the components of flat tubes 1 , corrugated fins 2 , tube sheets 3 with openings 4 for receiving the ends of the flat tubes 1 and with horrslhacks - and connecting transverse edges 5 , 6 , which form four corner regions exist.
  • the heat exchanger consists of collecting boxes 7 with two longitudinal walls 8 , 9 for connection to the connecting longitudinal edges 5 and side parts 10 with sealing caps 11 , for closing the lateral openings of the collecting boxes 7 , wherein the closure caps 11 have a bevelled edge 14 .
  • means 15 for fixing the heat exchanger at the edge of the collecting tank 6 and the edge 14 of the closure cap 11 are arranged, which cooperate. All mentioned parts of the heat exchanger are made of aluminum sheet, which is suitably coated with solder, for the metallic connection by means of a soldering process.
  • the longitudinal walls 8 , 9 of the manifolds 7 are arranged between the connecting longitudinal edges 5 of the tubesheets 3 , wherein projections 20 are provided on the longitudinal walls 8 , 9 , stuck in corresponding openings 30 in the tube sheets 3 .
  • the connecting transverse edges 6 of the tubesheets 3 have a contour cutout 40 which forms a tight and firm soldered connection with the closure caps 11 .
  • the projections 20 have a slightly conical shape, so that a certain guidance is ensured in the openings 30 and that at the same time it is ensured that the projections 20 fit tightly against the edge of the openings 30 .
  • the projections 20 and the openings 30 are arranged at appropriate intervals in order to fulfill their function.
  • the openings 30 in the tube sheet 3 are preferably arranged between the openings 4 for the flat tube ends, so that a maximum depth of the tube - rib block is ensured. Furthermore, they are preferably located directly on the connecting longitudinal edge 5 .
  • the contour cutout 40 of the connecting transverse edges 6 is provided between the connecting longitudinal edges 5 .
  • the contour cutout 40 corresponds approximately to the Kontor the cap 11 so that a solid and tight solder joint is achieved.
  • the contour of the cutout thus depends on the selected contour of the closure cap 11 .
  • FIG. 2 in conjunction with FIGS. 9 and 10 , shows the contour cutout 40 is formed in the exemplary embodiment so that the two connecting longitudinal edges 5 slightly above the remaining connecting transverse edge 6 of the tube sheet 3 protrude.
  • the protruding connecting longitudinal edges have the reference numeral 51 in FIGS. 2, 9 and 10.
  • a graduation 50 whose size approximately corresponds to the sheet thickness of the collecting boxes 7 , or the sheet thickness of the longitudinal walls 8 , 9 , also belongs on both sides.
  • the projecting connecting longitudinal edges 51 thus each receive a projection 20 between them and the edge 14 of the closure cap 11 .
  • the connection between the connecting transverse edge 5 and the closure cap 11 as shown in FIG. 12, be formed without a flange. 13 and 14, however, show a flange 41 , wherein in Fig. 13, the flange is directed downward and in Fig. 14 upwards to create a solid and tight solder joint even with thinner tube sheets 3 .
  • a cutout 16 is provided, into which a flap 17 has been bent on the transverse wall of the collecting box 7 in order to provide a provisional holding of the heat exchanger in the production phase.
  • the partial longitudinal section shown in FIG. 11 runs exactly through the mentioned means 15 for fixing and shows the tab 17 in the already bent state.
  • the assembly process of the heat exchanger is in the described embodiment as follows:
  • the flat tubes 1 are alternately assembled with the corrugated fins 2 to the so-called rib-tube block.
  • the side parts 10 are attached to the caps 11 .
  • a tube plate 3 is raised at each end of the flat tubes 1 , after which the ends of the flat tubes 1 are inserted into the openings 4 of the tubesheets 3 .
  • the collecting boxes 7 are placed on the tubesheets 3 , wherein the projections 20 are respectively inserted into the openings 30 .
  • the headers 7 are thereby fixed in their longitudinal direction.
  • a pressing of the connecting longitudinal edges 5 of the tube sheet 3 to the longitudinal walls 8 , 9 of the collecting tank 7 is achieved.
  • the mentioned means 15 are used for fixing, which are preferably formed in the form of the tabs 17 also mentioned, which are bent into the cutout 16 at the edge 14 of the cap 11 .
  • the heat exchanger is thus a self-contained unit that can be prepared for the soldering process.
  • FIG. 7 differs from FIG. 8 in that FIG. 7 shows a section in the region of a flat tube 1 and FIG. 8 shows another section in the region of the projections 20 .
  • FIGS. 5 and 6 also differ only because of the different cutting planes.
  • a heat exchanging medium into the collecting box 7 occurs, for example in the positions shown in Figs. 1 and 2 nozzles 70, and distributed to the flat tubes 1 to pass through to it.
  • An identical or similar collection box 7 is located on the one side not shown (in the longitudinal direction of the flat tubes) of the heat exchanger and another not shown nozzle is arranged either on the shown or not shown collection box 7 to dissipate the heat exchanging medium. Cooling air flows through the corrugated fins 2 and is in heat exchanging relationship with the mentioned medium.
  • only one side member 10 is shown, it being understood that a second side member is present on the second side not shown (transverse to the flat tubes) that is identical at least with respect to the features described herein.
  • the closure caps 11 are formed as individual parts, as has also been provided in the non-prepublished application. Even with such heat exchangers, a contour cutout 40 is provided in the connecting transverse edges 6 of the tubesheets 3 . Further, at the edges of the longitudinal walls 8 , 9 of the manifolds 7 projections 20 are provided, which are inserted into corresponding openings 30 in the tube sheets 3 . The mentioned openings 30 are not recognizable in FIG. 15, for which reason reference is made to FIG. 9 in this regard.
  • the fixing means 15 which are required in this embodiment rather than in the first embodiment, consist of clips formed on the edge 14 of the closure cap 11 .
