Definitions

  • the invention relates to a heat exchanger for motor vehicles, the Components of flat tubes, corrugated fins, tube sheets with openings for Recording the ends of the flat tubes and with connecting edges as well as with four Corner areas exist, and collection boxes with two longitudinal walls to Connection with the connection edges, from side parts with longitudinal edges and Caps for closing the lateral openings of the collecting tanks, wherein the closure caps have a bevelled edge and wherein all parts are made of aluminum, suitably coated with solder is to metallic connection by means of a soldering process.
  • Such a heat exchanger was registered with the DPMA on 17.08.02 and received the file number DE 102 37 769.3.
  • the side panels and the caps are either integrally formed in the application (there Fig. 7) or it acts around two individual parts (there Fig. 9).
  • the present application is intended to further manufacturing and functional improvements in heat exchangers show that have side panels with integrated caps.
  • the object of the invention is further production technology and / or show functional advantages of the heat exchanger.
  • Heat exchanger offers above all functional advantages because of at least 50%, preferably by more than 80% reduced cross-section of the connection between the side part and the cap allows it, the remaining Cut through connecting webs on the finished heat exchanger.
  • reduced cross-section is used in the forming of the lateral part achieved with the integrated cap by cutting the same.
  • reduced cross-section leads to an improved balance of Temperature gradients caused stresses in the heat exchanger, causing the Frequency of occurrence of material breaks in the heat exchanger is reduced.
  • An equipped with the characteristics of the independent claim 2 Heat exchanger also offers manufacturing advantages, because the provided means for fixing the heat exchanger the need for Reduce auxiliary devices to perform the soldering process.
  • FIGS. 1 and 2 each show a side part 9 with a cap 13 , at the edge 14 means for fixing the heat exchanger in the assembled state, as it can be seen approximately in Figs. 5 and 6, are arranged.
  • the means consist of a bar 22 arranged on the upper edge 14 and of U-shaped tabs 21 with insertion bevels 25 arranged on both lateral edges 14 .
  • a central web 20 is provided as a connection between the side part 9 and the closure cap 13
  • FIG. 2 two adjacent webs 20 are provided.
  • FIGS. 3 and 4 differ from FIGS. 1 and 2 in that there the means for fixing are not present and furthermore in that the longitudinal edges 11, 12 of the side part 9 are bent in the same direction as the edge 14 of FIG Cap 13 .
  • Figs. 1 and 2 the edge 14 in the opposite direction to the edges 11, been bent 12th
  • the side part 9 is not in a common vertical plane with the closure cap 13 . This is necessary in the embodiment shown for structural reasons, because, as for example.
  • Fig. 9 shows, between the side part 9 and the first flat tube 1, a corrugated fin 2 is arranged. As a result, the plane of the side part 9 is located farther from the center of the heat exchanger than the plane of the closure cap 13 .
  • the webs 20 have a kink or a bow to compensate for the difference between the two planes, wherein the kink can at the same time by temperature gradient caused changes in length or makes them easier.
  • FIGS. 9 and 10 individual parts made of aluminum sheet, such as flat tubes 1 and corrugated fins 2 , are assembled with tubesheets 3 .
  • the flat tubes 1 can, as is known, also be produced by means of extrusion molding, that is to say not of aluminum sheet.
  • the opposite ends of the flat tubes 1 are inserted into the corresponding openings 4 opposite tube sheets 3 .
  • only one end of the flat tubes 1 , or one side of the heat exchanger 1 is partially depicted. The other side not shown may be identical.
  • the openings 4 in the tube sheets 3 are provided with the flat tubes 1 and the center of the heat exchanger directed outlines 40 , which are often referred to as passages 40 , because they are produced by the similar-sounding forming process (pulling, pulling).
  • the ends of the flat tubes 1 do not extend to the surface of the tube bottom 3 , preferably they end relatively clearly below this surface in order to keep the pressure loss of the medium flowing within the heat exchanger even lower.
  • the medium for example the liquid coolant of an automobile engine or the charge air to be cooled, flows through the inlet port 60 into the collecting box 6 and distributes itself to the flat tubes 1 , in which it flows freely through the corrugated fins 2 flows, is cooled.
  • the outlet is located on the other collection box 6 , not shown, at the other end of the flat tubes. 1
  • the tube sheets 3 in the illustrated embodiment, two folded connection edges 5 and two non-folded connection edges. Furthermore, four corner areas A, B, C, D result. In FIG. 8, only the corner areas A and B have been designated. Since, as already mentioned, the figures are only partial views, the identical corner areas C, D present at the opposite end are not visible.
  • the collecting boxes 6 are open at both ends and have two folded longitudinal walls, each of which provide the connecting edge 7 and 8 , which serve the connection with the bent connecting edges 5 of the tube sheets 3 .
  • the soldering problem areas can be seen, which are present in the mentioned corner areas A, B, C, D.
  • connection in each corner region consists of the edge of the tube bottom 3 , the edge 14 of the closure cap 13 and the respective connection edge 7, 8 of the collecting box 6 .
  • the bent edge 14 of the cap 13 in the region of the connection was sharp-edged, ie formed with a significantly smaller bending radius than the rest of the bent edge 14th This was achieved by a rework, in which the sheet thickness of the cap 13, where the smaller bending radius is present, has been significantly reduced, which can be seen in particular in Figs. 8 and 14, but otherwise the subject of the introduction mentioned unpublished patent application DE 102 37 769.3.
  • the side parts 9 are added with the integrated caps 13 .
  • the header boxes 6 are attached.
  • the edge of the collecting boxes 6 is inserted into the U-shaped tabs 21 at the edge 14 of the closure caps 13 until an intimate contact between the edge of the collecting box 6 and the edge 14 of the closure cap 13 is established.
  • the latch 22 can be rotated over the edge of the collecting box 6 , as can be seen well in Fig. 6, whereby the heat exchanger is prepared for performing the soldering process.
  • the two tabs 21 at all ends of the headers 6 and the respective one bar 22 ensure a temporary hold of the assembled components.
  • FIGS. 11-14 differs essentially from the previously described exemplary embodiments in that the tabs 21 have been moved from the bent-over edge 14 of the closure caps 13 to the edge of the collecting boxes 6 .
  • the bent edge 14 has been provided with a projection 26 which engages in the associated tab 21 in the joined state (FIGS. 12-14) of the heat exchanger.
