Definitions

  • the invention relates to a whole-metal heat exchanger, consisting of flat tubes with two narrow - and two broad sides and ribs, which together with the flat tubes form a block, and from at least one collecting box, in which the ends of the flat tubes open, and with in Interspaced projections, wherein the spacings of the projections correspond to the spacings of the flat tubes, so that the projections in the region of the narrow sides engage in the ends of the flat tubes.
  • the heat exchanger described above and a manufacturing method have been described in the recently filed European patent application with the application number EP 05012589.7 shown and described.
  • the projections are arranged there on the longitudinal walls of the collecting tanks or on the longitudinal edges of individual tube sheets.
  • the collection boxes are thus formed in two parts, ie they consist of an upper cover part and of a so-called tube sheet having receiving openings for the pipe ends.
  • the object of the invention is to provide a heat exchanger which, compared to the described prior art, should have alternative features which likewise lead to a heat exchanger which achieves a smaller space requirement with comparatively good thermal-technical values.
  • the proposed heat exchanger leads to a number of advantages.
  • the seated in the flat tube ends projections on a comb-like additional part, such as metal strips or the like., which is connected to the wall of the header, keep the flat tubes during the subsequent soldering process to tension, so that the risk of so-called “collapse "the flat tubes, with the result of insufficient solder joints in the receiving openings, has been substantially reduced.
  • the invention allows Therefore, the use of flat tubes, the broad sides may have larger dimensions and thus avoids the production technically complex use of several Flachroh marinan in the direction of the depth of the flat-tube rib block. In other words, with the invention, heat exchangers can be made available in a much broader performance spectrum with much less modification effort.
  • the flat tubes extend across the entire depth of the header, there is virtually no space that would not be available for heat exchange purposes.
  • the flow-through cross-sectional area of the flat tubes is in a favorable ratio to the total occupied by the collecting box surface, which in turn is approximately equal to the relevant cross-sectional area occupied by the entire heat exchanger.
  • the frontal openings of the collecting tank are closed by per se known side parts, which are extended beyond the length of the flat tubes out.
  • the headers can be formed in one piece or multiple parts. Striking is a part which has a U-shaped cross-section, wherein the base portion is provided with receiving openings for the pipe ends and the two legs form the two walls of the collecting tank. Once the walls have been reshaped and brought together to form a room, one-piece collection boxes are available. If the walls remain essentially flat, a second part is necessary for the formation of a closed space, which is why two-part collection boxes are then present.
  • the receiving openings extend minimally into the walls of the collecting tank.
  • the projections are appropriately shaped so that the insertion thereof into the ends of the flat tubes is assisted.
  • the additional part is a comb-like sheet metal strip, which is easy to process by forming technology to produce the additional part.
  • the term "strip" encompasses all possible physical formations, so that it is therefore generally possible to speak of an additional part.
  • the mentioned Projections on the strips or additional parts may be first projections, in the event that second projections are provided on the strip.
  • the second protrusions are then arranged between the first protrusions. The second protrusions improve the assembly or preparation of the heat exchanger for the following soldering process.
  • the all-metal heat exchanger can be used everywhere in the widest sense with advantages where a small space requirement with good heat exchange efficiency should be present.
  • the inventor remembers to use such heat exchangers especially as air-cooled intercoolers in motor vehicles, but without excluding any other possible use, especially in the field of motor vehicles.
  • An all-metal heat exchanger is intended to be a heat exchanger whose constituents referred to in the claims are made of metal, preferably aluminum, regardless of whether later non-metallic parts which could be part of the system are attached to this heat exchanger or Not.
  • Fig. 1 shows an exploded view of the heat exchanger according to the invention.
  • Figures 2 and 3 show perspective views of the finished heat exchanger.
  • Figures 4 and 5 show perspective views of a portion of the heat exchanger in a mounting situation.
  • Fig. 6 shows the end of a flat tube.
  • All illustrated individual parts of the heat exchanger are made of metal, preferably of aluminum or aluminum alloys, which is expediently coated with a layer of solder.
  • the items such as flat tubes 1, 4 ribs , 6 manifolds and side panels 30 are made of aluminum sheets, which, however, is not excluded that, for example, the flat tubes 1 could also be produced as drawn tubes.
  • the flat tubes 1 have an approximately rectangular cross-section, but the narrow sides 2 can also be curved slightly outwards.
  • the flat tubes 1 are then stacked with the ribs 4 to form a flat tube fins block. At least in that Embodiment, which is shown in Figs.
  • the collecting boxes 6 also include the tube plates 5 , so that therefore no classical tube plates are provided as a single part, which can be taken from Figs. 1, 4 and 5.
  • the collecting box 6 has a base portion 60 , from which two bent walls 61 of the collecting box 6 depart. The walls 61 are deformed and they can be connected by means of a longitudinal weld, not shown, to form the header 6 .
  • receiving openings 62 are provided for the flat tube ends, which should therefore match the spacing of the flat tubes 1 with the distances of the receiving openings 62 .
  • a rather striking feature is that the receiving openings 62 extend into the walls 61 , ie they extend to just above the bending edge of the walls 61 on the base portion 60, which is clearly enough from the Fig. 5 at reference 62 can be seen ,
  • a strip 10 is located on all the walls 61 of the two collecting boxes 6.
  • the strips 10 were designed with additional functions, such as holding functions 70 for accessories not shown.
  • the provision of strips 10 on all walls 61 is not an inevitable measure.
  • Fig. 3 Another advantage of the strip 10 is apparent from Fig. 3. It can be seen there that the strip 10, which is formed with the mentioned additional functions, can also contribute to the strength of the collecting tank 6 . It can be seen in Fig. 3 that the strip 10 extends over a substantial part of the wall 61 of the collecting box, and it is soldered to this wall 61 .
  • the projections 11 can be provided with such a contour that the sliding of the same is facilitated in the flat tubes 1 .
  • first projections 11 are first projections 11 .
  • second projections 12 are arranged between two first projections 11 .
  • the second projections 12 cause a counter-torque of the strip 10, which otherwise, when the first projections 11 are in the flat tube ends, could tend to stick from the wall 61 , which is undesirable. Since the second projections 12 rest against the ribs 4 from the outside, this is prevented, or at least counteracted.
  • FIGS. 4 and 5 it is advantageous to form at the ends of the strip 10 includes a hook 13 which is suitable to hold the side part 30 on the outer rib 4 determined. This also supports the cohesion of the entire heat exchanger before soldering. Further, also by the above-mentioned "sticking" of the strip 10 is suppressed by the wall 61 .
  • brackets which are to hold the side panels 30 in the frontal openings 65 of the collecting tank 6 , are omitted, which is also a manufacturing advantage.
  • Fig. 6 shows by way of example the end of a flat tube 1, consisting of two long sides 3 and two short sides 2, in which two protrusions 11 and, for example, an internal insert 80 are located.
  • the projections 11 are soldered inside tight on the narrow sides 2 .
  • the invention accordingly provides an innovative product which, compared to the state of the art, leaves only little to be desired.
