Definitions

  • the heat exchanger described above is for example from the DE 198 19 247 A1 known.
  • the projections correspond there with openings in the tube sheets.
  • a provisional cohesion of the items is provided before performing the soldering process.
  • the cost of soldering auxiliary device can be significantly reduced.
  • a certain disadvantage of the known heat exchanger is that there is still a clear overhang of the tube bottom over the rib-flat tube block, which could be regarded as an unnecessary space requirement.
  • the ratio of the cross sections occupied by the flat tubes is not optimal in comparison with the entire cross section of the heat exchanger or its tube plates, so that improvements are possible with regard to efficient heat exchange.
  • the flat tubes extend over the entire depth of the tubesheet, preferably even beyond, 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 more favorable ratio to the total occupied by the tube sheet surface, which in turn is about equal to the relevant area, which is occupied by the entire heat exchanger.
  • the first alternative mentioned as mentioned, preferred because it is better to prevent the already mentioned "collapse" of the flat tubes, since in this case the edge of the headers with the projections from the outside rests on the edge of the tube sheet and therefore because the projections against Forces which act in the direction of the broad side, ie transversely to the longitudinal direction of the flat tubes, are particularly resistant. Furthermore, this alternative also appears to be more favorable in terms of creating dense connections.
  • the projections each touch the narrow sides of the flat tubes from the inside and they are preferably soldered there.
  • each collection box has frontal openings.
  • each collection box turns out to be merely a sheet with two folds, which is also advantageous in terms of manufacturing technology.
  • 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.
  • 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 the aforementioned "incidence "the flat tubes, with the result of insufficient solder joints in the receiving openings, has been significantly reduced by the provision of the additional part.
  • the advantages of the prior art are retained, i. H.
  • the cost of soldering auxiliary devices is significantly reduced, since the strips (additional parts) at the ends have hooks that support the cohesion of the mounted items of the heat exchanger by grabbing over the side panels.
  • 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 the strip second projections are provided.
  • 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 inventive method for producing a whole-metal heat exchanger wherein flat tubes and ribs are merged into a flat-tube fin block, after which tube plates are attached to the ends of the flat tubes and finally collecting boxes are attached with their edges to the edges of the tube sheets is characterized in that arranged on a component projections in the narrow sides of the flat tubes are inserted in the ends thereof.
  • 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, ribs 4, tubesheets 5, 6 manifolds and side panels 30 are made of 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. In the embodiment shown, internal inserts are located in the flat tubes 1. The flat tubes 1 are then stacked with the ribs 4 to form a flat tube fins block.
  • the webs 22 are present.
  • the webs 22 may be formed profiled to increase their rigidity.
  • the side parts 30 are attached, which simultaneously close the frontal openings 60 of the collecting tanks 6 .
  • the side panels 30 each have a cup-shaped reshaped at their ends A closure piece that fits into the opening 60 .
  • deformable holding elements 61 which engage in a slot 62 of the side parts, the side parts 30 are pre-fixed and hold the individual parts of the heat exchanger together.
  • the heat exchanger is substantially prepared to carry out the CAB brazing process. All connections are made in a single pass in a brazing furnace.
  • the shape of the projections 11 is suitably adapted to the existing in the narrow sides 2 contour of the flat tubes 1 , so that both the insertion is facilitated as well as dense solder joints are provided. This also certain manufacturing tolerances are absorbed.
  • the distance between the projections 11 at the edge of the manifolds 6 corresponds to the distance between the flat tubes 1 in the row or with the height of the arranged between the flat tubes 1 ribs 4.
  • certain tolerances must be allowed, however, by the appropriate shape of the projections 11th can be compensated. (see the description of the Fig. 15 and 16 further down)
  • the tubesheets 5 during assembly can also be pushed transversely to their longitudinal direction, or in the direction of the broad sides 3 of the flat tube ends, onto the same. In the prior art, this requires a movement in the longitudinal direction of the flat tubes. There is talk of "pulling up" the tubesheets.
  • the projections 11 have a favorable effect on the reduction of the harmful bypass, which comes as a further advantage of the invention to bear.
  • the small gaps in the corners of the flat tube 1 have their cause in the representation. In practice, they are not available or are securely closed during the soldering process. The mentioned gaps will also level when inserting the projections 11 , because the projections 11 hold both broad sides 3 in the direction of the arrow under a certain tension.
  • the collecting boxes 6 also include the tubesheets 5 , so that therefore no classical tubesheets are provided as a single part, which can be taken from the mentioned figures.
  • the collecting box 6 has a base section 106 , from which two bent walls 107 of the collecting tank 6 depart. The walls 107 are deformed and they can be connected by means of a longitudinal weld, not shown, to form the header 6 .
  • receiving openings 21 are provided for the flat tube ends, which should therefore match the distances of the flat tubes 1 with the distances of the receiving openings 21 .
  • strip 110 comes from the Fig. 12 out.
  • the strip 110 with the mentioned additional functions is formed, can also make a contribution to the strength of the collecting tank 6 .
  • FIGS. 13 and 14 It is further apparent that it is advantageous to form at the ends of the strip 110 a hook 13 which is adapted to hold the side member 30 to the outer rib 4 firmly. This also supports the cohesion of the entire heat exchanger before soldering. Furthermore, it also suppresses the above-mentioned "sticking out" of the strip 110 from the wall 107 . It can also be used in the Fig. 1 With 61 and 62 shown brackets, which should hold the side panels 30 in the frontal openings 60 of the collecting tank 6 , are omitted, which is also a manufacturing advantage.
  • the Fig. 15 shows a section with only one projection 11.
  • the projections 11 have been performed on the type of cutting teeth 111 .
  • length tolerances in the flat tubes which are approximately in the range of +/- 1.0mm are better absorbed.
  • sharp edges 112 were formed, which are also in the radii, d. h in the region of the transition from the projection 11 in the wall of the collecting tank 6 or the additional part or the tube bottom extend.
  • the sharp edged edges 112 intersect these ends when inserting the projections 11 into the flat tube ends, somewhat at the flat tubes which are in the upper length tolerance range, and "fold" these ends slightly outwards. That is from the Fig. 16 easy to recognize at k.
  • the middle tube is slightly longer there than the other two tubes.
  • the sharp edge of the projections 11 is produced for example by cold forming.
  • the difference in thickness between the projections 11 and the wall of the flat tubes supports this procedure.
  • the wall of the collecting box 6, from which the projections 11 are formed for example, may be about 1.0 - 2.0mm thick while the thickness of the
  • the invention accordingly provides an innovative product which, compared to the state of the art, leaves only little to be desired.
