Definitions

  • the invention relates to a heat exchanger for motor vehicles, according to the Preamble of claim 1 and a method for producing the Heat exchanger according to the preamble of claim 9.
  • the heat exchanger is known from EP 1 004 841 A2.
  • the process reliable Manufacture of the heat exchanger is sometimes not guaranteed because it is not what is said is how the connection areas, which are difficult to master in terms of soldering technology between the tube sheet, the side part and the caps of the front open collection boxes should be formed.
  • the items are out Solder-coated aluminum sheet has been produced, which is used for heat exchangers be put together.
  • Heat exchangers for automotive radiators have been part of the process for many decades State of the art and have both what their process-safe manufacturability concerns as well as proven in all their functional properties.
  • Example was described in German utility model 7 229 162, even if there the tube sheets were divided into many small segments.
  • the collection boxes are made of plastic and on the circumferential edge mechanically attached to the tube sheet. Because the edge has a clear protrusion over the cooling network of flat tubes and corrugated fins, need such Relatively large installation space. Furthermore, recycling is due to the use different materials difficult.
  • a coolant condenser is described in DE 195 36 999 A1. Are there too the caps mentioned above for closing the front openings of the Collection boxes available. Because the coolant condenser sockets are in two parts, one part can be regarded as a tube sheet, because it has Openings in which the ends of the flat tubes are arranged and the other part can be seen as a box. Both parts are in one Solder edge connected.
  • the object of the invention is to provide a heat exchanger for Motor vehicles with the features of the preamble, which are further developed in this way should be that the reliable production is guaranteed, the required installation space for the heat exchanger should remain small.
  • the at least one bending edge of the connecting edges and / or the folded edges located within the connection between the side part or the sealing cap and the tube sheet and the longitudinal wall of the collecting box should have a smaller bending radius than outside the connection, the inside of the Connection existing sheet thickness of the side part or the closure cap should be smaller than outside the connection.
  • the inventors very specifically use tube sheets for their heat exchanger, because they see it as justifiable to increase the weight of the motor vehicle radiator (slightly) compared to the heat exchangers described without tube sheets, because they achieve decisive progress in terms of manufacturability and already existing machines and systems to be able to use.
  • the tube sheets can have two bevelled connection longitudinal edges and two bevelled connection cross edges, the sheet metal thickness of the tube sheets inside the connection being smaller than outside the connection.
  • the longitudinal connection and the transverse connection edges of the tube sheets can be folded in the direction of the collecting box or in the direction of the flat tubes.
  • the tube sheets can also have only two have folded connecting longitudinal edges, the connecting transverse edges are executed without a bevel, so that the sheet thickness of the Tube sheets are available.
  • the side parts can be designed with extensions that as Caps work, or the side parts and caps are individual parts.
  • the at least one bending edge of the connecting edges and / or the edges lying within the connection between the side part or the sealing cap and the tube sheet and the longitudinal wall of the collecting tank is provided with a smaller bending radius than outside the connection, for which purpose the inside the existing sheet thickness at the bending edge of the connection is reduced compared to the sheet thickness outside the connection and that the smaller bending radii or the reduced sheet thickness are produced in a forming operation following the manufacture of the parts before they are assembled into the heat exchanger.
  • the sheet thickness can be reduced on both legs forming a bending edge or only on one of the two legs.
  • tube sheets 3 are present, as are shown in FIG. 4.
  • the tube sheets 3 were only shown in a cutout, but they have two opposite connecting longitudinal edges 5 and two opposite connecting transverse edges 15 , so that the corner regions A , B , C and D are present.
  • the connecting edges 5 and 15 are directed towards the flat tubes 1 or folded.
  • openings 4 in a known manner, which are to later accommodate the ends of the flat tubes 1 .
  • the bending radius (outside) should preferably not be greater than 0.8 mm, so that a definable, very small open cross section is formed on the assembled heat exchanger at point P (FIG. 1), which can be closed without problems during the subsequent soldering.
  • the inside of the longitudinal edges 7 and 8 of the collecting boxes 6 is coated with solder, so that a sufficient amount of solder is available to close the small, open cross section.
  • larger open cross sections could be easily sealed by adding solder. 2 and 4 of GB 20 98 313, relatively large open cross sections can be seen.
  • the sheet thickness a in both legs of the respective bending edge 30 was reduced both on the tube sheets 3 and on the side parts 9 , 10 in order to realize the smaller bending radius.
  • the side parts 9, 10 of this embodiment are extended and therefore have the caps 13 with the beveled edge 14 .
  • the collecting boxes 6 are very simple and inexpensive to produce, because it is in principle a sheet bent on both sides, the two bends representing the longitudinal walls 7 and 8 of the collecting boxes 6 .
  • the collecting boxes 6 are open towards the front ends.
  • closure caps 13 are slightly bent relative to the side parts 9, 10 in order to facilitate the assembly of the heat exchanger, in particular the mounting of the tube sheets 3 onto the ends of the flat tubes 1 , which were previously packaged with the corrugated fins 2 are. Then the side parts 9, 10 are attached and the tube sheets 3 are drawn on. The above-mentioned bending of the closure caps 13 has been indicated in FIG. 3 by a dashed line. Finally, it can be seen from FIG. 2 that the flat tubes 1 or the openings 4 in the tube sheet 3 , which openings are adapted to the flat tubes 1 , approach the connecting longitudinal edges 5 of the tube sheet 3 .
  • the overall depth of the heat exchanger is only insignificantly greater than the depth that can be used for heat exchange, so that the space required for the heat exchanger in the motor vehicle can be used very efficiently.
  • the flat tubes 1 preferably have no deformations at the ends, which contributes to cost-effective production.
  • the exemplary embodiment shown in FIGS. 6, 7 and 8 differs from the exemplary embodiment described in that other tube sheets 3 have been provided. These tube sheets 3 are shown in FIG. 6. Further possible variations of the tube sheets 3 can be seen from FIG. 10.
  • the tube sheets 3 from FIG. 6 have two connecting longitudinal edges 5 bent towards the collecting tank 6 .
  • the connecting transverse edges 15 are designed without a bevel.
  • the sheet thickness of the tube sheets 3 is approximately 1.5 mm.
  • This thickness is sufficient to ensure, as was shown in FIGS. 7 and 8, a firm and tight solder connection to the closure caps 13 and the longitudinal edges 7, 8 of the collecting boxes 6 .
  • the thinning of the sheet thickness or the reduction of the bending radius was only carried out in the bending edges 30 of the closure caps 13 because a relatively sharp-edged design is already present in the corner regions A, B, C, D of the tube sheet 3 .
  • the exemplary embodiment from FIG. 9 has individual closure caps 13 with a beveled edge 14 and consequently also side parts 9, 10 , which are individual parts.
  • the sealing caps 13 were partially thinned in their bending edge 30 towards the edge 14 in order to reduce the bending radius compared to the rest of the bending radius.
  • tube sheets 3 as shown in FIG. 4, were used, the ends of the side parts 9, 10 being encompassed by the cross-connecting edge 15 of the tube sheets 3 .
  • the corner areas A, B, C, D have been designed as shown and described in FIG. 1, so that solid and tight soldered connections can also be expected in these problem areas.
  • tube sheets 3 were used, which can be seen in the picture at the top of FIG. 10, that is, tube sheets 3 without a bent connecting transverse edge 15 , the two longitudinal connecting edges 5 being directed towards the flat tubes 1 .
  • the connecting edges 15 of the tube sheets 3 do not have any bends, excellent soldered connections can also be expected here, because the bent edge 14 running around the entire circumference of the sealing caps 13 ensures this. It is irrelevant whether the edge 14 faces outwards, as shown, or also inwards, into the collecting box 6.
  • FIGS. 14 a and 14b show examples of how the thinning of the sheet thickness in the bending edge 30 can be formed within the connection 31 described.
  • a thinning was provided only in one leg 5 of the bending edge 30 in the tube sheet 3 , which already leads to a sufficient reduction in the bending radius.
  • the bending edge 30 on the side parts 9, 10 or on the bent edge of the closure cap 13 was not reduced in these exemplary embodiments.
  • the plate thickness b of the tubesheets 3 and that of a side of the parts 9, 10 or the cap 13 may be approximately the same size.
  • the sheet thickness a or b has been reduced by approximately 1/3, as shown in FIGS. 14a and 14b.
  • the size of the selected outer bending radius also depends on whether only one bending edge 30 is provided with a smaller bending radius, as shown in FIGS. 5 and 14, or whether both bending edges 30 have a reduced bending radius .
  • reducing the bending radius or sheet thickness a, b one can go as far as the production-technically feasible limit, with the person skilled in the art of course not choosing any radii smaller than necessary.
  • the bending edges to the bent longitudinal edges 11, 12 have a smaller bending radius.
  • an inward bend is shown transversely to the longitudinal direction of the side parts 9, 10 , which in the second illustration points outward.
  • the longitudinal edges 11, 12 can be formed continuously or can also be cut out.
  • training 20 can be provided in a known manner in order to permit the expansion of the side parts 9, 10 under the influence of temperature fluctuations.
