Definitions

  • the invention relates to a heat exchanger for motor vehicles with a finned tube block consisting of flat tubes with fins arranged between them, the shaped ends of the flat tubes opening into opposite collecting or deflection boxes and being connected to one another with the long sides of the shaped ends, the ends being connected to one another the flat tubes are in contact with the connecting edges of the collecting or deflection boxes and are connected by means of soldering.
  • a heat exchanger for motor vehicles with a finned tube block consisting of flat tubes with fins arranged between them, the shaped ends of the flat tubes opening into opposite collecting or deflection boxes and being connected to one another with the long sides of the shaped ends, the ends being connected to one another the flat tubes are in contact with the connecting edges of the collecting or deflection boxes and are connected by means of soldering.
  • Such heat exchange is already known from EP 0 775 884.
  • the invention further relates to a method for producing such heat exchangers, in which the finned tube block is soldered to the collecting
  • the ends of welded or extruded or drawn flat tubes have a separating cut which divides the ends of the flat tubes into two parts, that at least one of the parts of each flat tube has a bend transversely to the longitudinal direction which leads to a connecting surface between The long side of the flat tube and the long side of the part of the adjacent flat tube leads and that the collecting or deflection boxes with their connecting edges extend over the bend and the cut section and are connected to the narrow sides of the flat tubes.
  • the flat tubes are welded have one or more longitudinal beads, which form a plurality of flow channels in the flat tube, wherein the longitudinal beads within the separated section are eliminated by forming. Welded flat tubes are cheaper than drawn flat tubes.
  • the material of the longitudinal beads within the cut-off section is pressed outwards into the longitudinal edges, as a result of which the connecting surfaces which form at the ends of the adjacent flat tubes are smooth and cause little problems with regard to a tight soldered connection.
  • This claim is only optional.
  • the longitudinal seam is arranged outside the separating cut, preferably on a long side of the flat tube, in the vicinity of a narrow side of the flat tube. This simplifies the application of the separating cut.
  • the flat tubes are drawn or extruded tubes and have one or more longitudinal walls for subdivision into several flow channels. This is particularly advantageous with coolant coolers.
  • longitudinal beads or longitudinal walls can be dispensed with. An indoor insert is provided for this case.
  • Claim 7 provides that both ends or both parts of each flat tube each have two bends arranged transversely to the longitudinal direction of the flat tube, one bend being arranged approximately where the connecting surface of the long side of the one flat tube begins with the long side of the adjacent flat tube and the other bend is provided approximately where the cut-off section of the flat tubes begins or ends.
  • the separating cut is preferably arranged parallel to the long sides of each flat tube, so that both end faces of the flat tube are separated. This has characterized an advantageous embodiment of the invention.
  • claim 1 also includes designs with only one bend, namely that at the end of the cut section where the flat tube begins. Where the connection surface begins, there may also be a gradual transition into the connection surface.
  • Claim 8 provides alternatively that only one of the parts mentioned has a bend and the other part remains smooth.
  • the long sides of the flat tubes are essentially smooth on the side on which they form a connecting surface with the long side of the adjacent flat tube. It is advantageous if one or more pressure joining points are arranged between the long sides or in the connecting surface.
  • the method according to the invention provides that the ends of the flat tubes are separated and at least one of the two parts of each flat tube formed after the separation is bent transversely to the longitudinal direction of the flat tubes in order to form a connecting surface with the longitudinal side of the adjacent flat tube that the collecting or Deflection boxes with their connecting edges are pushed over the ribbed flat tube block and the connecting edges are connected to the narrow sides of the separated parts of the flat tubes.
  • the separation can be carried out with a laser beam or a liquid jet or by means of conventional separating means and is preferably carried out parallel to the long sides of the flat tubes, exactly in the middle between the two long sides. It is preferably provided that both parts of the flat tubes are bent once or twice across the longitudinal direction of the flat tubes.
  • the at least one separating cut is arranged outside the center line on at least one of the two narrow sides. The separating cut should preferably be arranged parallel to both longitudinal sides of the flat tube, that is to say on both narrow sides outside their center line.
  • the attachment of at least one off-center separating cut is very advantageous for heat exchangers with flat tubes with somewhat wider narrow sides, because the narrower, separated part of the ends of the flat tubes can be shaped or bent more easily.
  • Claim 13 provides for two, preferably parallel, eccentric separating cuts to be arranged in the narrow sides of the ends of the flat tubes, the central part resulting from the separating cuts remaining undeformed and both lateral parts being bent so that their long sides abut the long sides of adjacent flat tube ends.
  • the cutout is preferably carried out with a tool with which the Cut out in both opposite narrow sides in one operation can.
  • the subsequent turning of the narrow parts can be done simultaneously the attachment of the cutout, but also later, after the assembly of the Ribs - flat tube blocks.
  • the coolers 1 consist of flat tubes 2 and corrugated fins 3 arranged between them .
  • the corrugated fins 3 were not drawn in FIGS. 1 and 2, but can be seen, for example, in FIG. 3.
  • the partial view in FIG. 1 shows only one collecting box 5. It goes without saying that the other collecting box 5 is arranged identically at the opposite ends 4 of the flat tubes 2 . All parts are made of aluminum and are coated with solder as required.
  • the collecting boxes 5 are of the simplest geometrical shape, so that they can be produced very inexpensively using known methods of metal forming.
  • Each collecting box 5 has two connecting edges 7 with which it overlaps the narrow sides 11 of the flat tubes 2 at the ends 4 in the section 12 (FIG. 2).
  • the ends 4 of the compartment tubes 2 each have a separating cut 8 .
  • the separating cut 8 runs in the direction of the large diameter D of the flat tubes 2, or parallel to the long sides 6. This has the advantage that both narrow sides 11 of the flat tubes 2 are wide enough to make a firm and tight connection with the connecting edges 7 ,
  • the ends 4 of the flat tubes have two parts 2a and 2b .
  • the parts 2a and 2b are bent transversely to the longitudinal direction of the flat tubes 2 , ie they have two bends 9 according to FIGS. 1, 2, 3, 8, 10. As the figures show, these bends 9 are not necessarily sharp bends.
  • a bend 9 is understood to mean at least one change in direction.
  • the specific design of the bends 9 depends on the distance between the flat tubes 2 and the height of the corrugated fins 3 in the fin-tube block.
  • the turns 9 cause the longitudinal side 6 of a flat tube 2 with the longitudinal side 6 of the part 2b of the adjacent flat tube 2 are each give a compound surface 10 of the part 2a.
  • the ends 4 of the flat tubes 2 are cut open after the flat tubes 2 have been cut to length.
  • the cut flat tubes 2 can then be joined together with the corrugated fins 3 to form a fin-tube block.
  • the parts 2a and 2b can then be bent as described.
  • the collecting boxes are block 5 is mounted in such a way that their joining edges are pushed 7 on both sides over the separated portion 12 of the ends 4 of the flat tubes 2 - to the thus prepared ribs - tube.
  • the connecting edges 7 also include the bends 9 , which is particularly evident from FIG. 3.
  • the collecting boxes 5 extend with their connecting edges 7 to just below the section 12. It is also possible to make the bends 9 directly after the ends 4 of the flat tubes 2 have been separated and only then to join the finned tube block.
  • the partial view of the cooler 1 in FIG. 3 further shows that, in the embodiments described so far, both parts 2a and 2b have been bent and 2 connecting surfaces 10 form due to the abutment of the longitudinal sides 6 of adjacent flat tubes.
  • the end faces of the collecting boxes 5 are closed with a cover 20 .
  • 4 shows the section A - A through part of the cooler 1.
  • the section runs just below the cut section 12 and therefore shows the flat tubes 2, which are not cut there.
  • the flat tubes 2 have long sides 6 and narrow sides 11, the narrow sides 11 being already connected to the connecting edge 7 of the header boxes 5 in this area.
  • 5 shows a section through the connecting surfaces 10 in FIG. 3. This shows what has already been mentioned above that the longitudinal sides 6 of adjacent flat tubes 2 form the connecting surfaces 10 , namely through part 2a of a flat tube 2 and one Part 2b of the adjacent flat tube 2. Both parts 2a and 2b have bends 9 .
  • FIG. 7 shows an exemplary embodiment in which flat tubes 2 welded with a longitudinal seam 14 have been used.
  • the longitudinal seam 14 is located in a longitudinal wall 6 of the flat tube 2, but in relative proximity to a narrow side 11, because there is a higher rigidity in the tube, which facilitates the connection by means of welding.
  • the weld seam 14 should be arranged at least outside the separating cut 8 .
  • FIG. 8 an embodiment is shown in which flat tubes 2 , each provided with a longitudinal bead 13 on both longitudinal sides 6 , are used.
  • the longitudinal beads 13 lie one on top of the other and because they are soldered to one another, two flow channels 16 are formed in the flat tube 2.
  • the longitudinal beads 13 could be disruptive in the connecting surfaces 10 , that is to say there could be leaks here. It has therefore been provided in this exemplary embodiment to remove the longitudinal beads 13 in the region of the connecting surfaces 10 by pressing them flat.
  • the material required for the longitudinal beads 13 has been pressed outwards and leads to an enlargement of the narrow sides 11 within the area of the connecting surfaces 10, which is shown in FIG. 8 but in particular in FIG. 10.
  • FIG. 12 is a partial side view of the fins 3 - tube 2 - block with bent ends 4 of the flat tubes 2.
  • the detail W has been drawn in, which is shown in FIGS. 13 and 14 in two different versions.
  • the separating cut 8 has an approximately circular hole 21 at its beginning or end. Something like this has proven to be advantageous if the bend 9 has to be relatively large because the tearing of the narrow sides 11 of the flat tubes 2 can be counteracted.
  • the holes 21 can e.g. B. in the manufacture of the separating cuts 8 by means of a laser beam or water jet, by piercing the beam there and then leading to the end 4 of the flat tube 2 . In most cases, however, such end crater-like holes 21 are not required and have not been provided according to FIG. 14.
  • 15 and 16 show a further variant in which only the parts 2b of the ends 4 of the flat tubes 2 have been bent. Parts 2a remain straight.
  • 6 connecting surfaces 10 are formed with the adjacent longitudinal sides.
  • 17 shows a section with three flat tubes 2, in which the separating cut 8 has been made, whereby two parts 2a; 2b arise. The depth of the separating cut 8 determines the size of the cut section 12 .
  • the separating cut 8 lies exactly between the two long sides 6.
  • Fig. 18 shows an additional measure, which consists in that between the adjacent longitudinal sides 6 of two adjacent flat tubes 2, or their parts 2a; 2b, one or more pressure joining points 22 have been arranged. Such pressure joining points 22 are known to be attached using suitable forming tools.
  • the pressure joining points 22 can take place, for example, together with the attachment of the bends 9 , if the bends 9 are to be attached after the ribs 3- pipe 2- block have been joined together. If the bends 9 are already made after the flat tubes have been cut to length, ie before the ribs 3- tube 2 block have been joined, an additional step on the joined ribs 3- tube 2 block is required for the production of the pressure joining points 22 .
  • the pressure joining points 22 cause the ribs 3- tube 2- block to be held together firmly before the soldering, so that auxiliary devices can be dispensed with or their expenditure can at least be reduced.
  • FIG. 19 to 28 is an air-cooled intercooler for motor vehicles, which consists of flat tubes 2 and corrugated fins 3 arranged between them.
  • the flat tubes 2 are welded, extruded or drawn.
  • the partial view in FIG. 19 shows only one collecting box 5.
  • the other collecting box 5 is arranged identically at the opposite ends 4 of the flat tubes 2 . All parts are made of aluminum and are coated with solder as required.
  • the collecting boxes 5 are of the simplest geometrical shape, so that they can be produced very inexpensively using known methods of metal forming.
  • Each collecting box 5 has two connecting edges 7, with which it engages over the narrow sides 11 of the flat tubes 2 at the ends 4 in the section which has been separated.
  • the ends 4 of the compartment tubes 2 each have a separating cut 8 .
  • the separating cut 8 runs in the direction of the large diameter of the flat tubes 2, or parallel to the long sides 6. This has the advantage that both narrow sides 11 of the flat tubes 2 are wide enough to make a firm and tight connection with the connecting edges 7 .
  • the ends 4 of the flat tubes After the separating cut 8 has been made at the ends 4 of the flat tubes 2 - specifically outside the center 31 of their narrow sides 11 - the ends 4 of the flat tubes have two parts 2a and 2b .
  • the wider parts 2a remain undeformed, while the narrower parts 2b have a bend 9 .
  • the bends 9 are designed so that the long side 6 of the flat tubes 2 of the narrower parts 2b abuts the long side 6 of the adjacent flat tube 2 , in each case on the long side 6, which belongs to the non-bent, wider part 2a , which the Fig. 19 clearly shows.
  • undeformed side parts 30 were used which at the same time close the front openings of the collecting boxes 5 .
  • 23 to 25 to be described below relate to an exemplary embodiment in which the narrow sides 11 of the flat tubes 2 are significantly wider than those in the exemplary embodiment described above.
  • a variant was therefore chosen here in which the ends 4 of the flat tubes 2 each have two separating cuts 8 on their narrow sides 11 .
  • 24 and 25 show in detail, the side parts 2a and 2b are of the same size and shape in this case and they both have the bends 9 .
  • the middle part 2c remains undeformed. In particular, it can be seen that these undeformed middle parts 2c have a favorable effect on the soldered connection between the connecting edges 7 of the header boxes 5 and the narrow sides 11 of the flat tubes 2 , because the middle parts 2c are also connected to the connecting edge 7 .
  • the bends 9 are also carried out here so that the long side 6 of the flat tube 2 or the narrower part 2a bears against the long side 6 of the corresponding part 2b of the adjacent flat tube 2 , so that they can be tightly connected by means of soldering.
  • This is also shown in particular by FIGS. 19, 22 and 23.
  • Shortly below the separating cut 8 in the flat tube ends 4 the ends 4 of the flat tubes 2 have not yet been separated. There, too, the narrow sides 11 of the flat tubes 2 are already connected to the connecting edges 7 of the collecting boxes 5 .
  • Fig. 19, 23 In the flat tubes 2 there is an inner insert, which ensures turbulence in the charge air and efficient heat exchange.
  • FIG. 19 further shows that in this exemplary embodiment continuous, deformed side panels 30 were used.
  • Such side parts 30 also have the next embodiment that is shown in FIGS. 26, 27 and 28.
  • the narrow sides 11 of the flat tubes 2 are first provided with a cutout, as is shown in FIG. 27.
  • the cutout takes up about 50% of the width B of the narrow side 11 of the flat tubes 2 , so that sufficiently wide edges remain on the parts 2a and 2b , which allow a secure connection at the connecting edges 7 .
