Definitions

  • the invention relates to manifold plates, or manifolds, for heat exchangers, in particular for motor vehicles, and more particularly those which comprise in a central part at least one row of parallel holes suitable for receiving ends of tubes.
  • the parallel holes are generally produced in stampings, by punching.
  • a second punching step holes are made, one by stamping, and the shapes and dimensions of which are adapted to the cross section of tubes to be introduced.
  • the stamping carried out in the first step can only correspond to a single type of tube, the dimensions of which are chosen.
  • one of the objects of the invention is to provide a collector which does not have the drawback of the collectors of the prior art.
  • the invention provides a manifold for a heat exchanger of the type described in the introduction, in which each hole is made in a deep-drawn comprising at least two aligned indentations, of respective dimensions chosen, and capable of being punched individually or in combination , by punches of different characteristic dimensions in at least the alignment direction of the indentations, to allow the passage of tubes of different dimensions in at least this alignment direction.
  • each imprint is capable of being punched, by punches of different characteristic dimensions, in a direction perpendicular to the direction of alignment of the imprints of a stamped, to allow the passage of tubes d 'at least two different dimensions in this direction perpendicular to the alignment.
  • a single stamping tool makes it possible to produce stampings whose aligned imprints allow the production of holes of different sections.
  • a single footprint will suffice to make a small hole, while two aligned and consecutive footprints will allow for example the production of a larger hole, or two smaller holes.
  • At least one of the imprints of a stamped has a dimension in the direction of alignment which is different from the dimension (s) of the other (or the other) imprint (s).
  • each stamp includes three aligned indentations capable of being punched individually or in combination to allow the passage of tubes of three different dimensions in the direction of alignment, and of five different dimensions in a direction perpendicular to this direction of alignment.
  • a heat exchanger generally comprises one or two fluid boxes (not shown) into which open the ends of metal tubes 1 (see FIG. 5), and forming a bundle of tubes spaced by fins.
  • collector plate 2 which also forms the cover of the fluid box.
  • the collector plate 2 comprises, on the one hand, a central part called "bottom”, and on the other hand, over the entire periphery of its central part, a shaped peripheral edge 4, for example by folding, which delimits a groove 5 U-shaped arranged to accommodate a peripheral heel formed on the periphery of the wall forming the fluid box.
  • Each pressed 6-i comprises a hole 7 (in the example illustrated in FIG. 1 only the pressed 6-3 is provided with a hole) capable of receiving one end of the tube 1.
  • the stampings are preferably intended to accommodate oblong tubes (also called flat tubes) having a small axis B (or width), and a large axis A (or length).
  • oblong tubes also called flat tubes
  • the tubes are positioned in the plate manifold 2 parallel to the short side, or transverse side, of the manifold plate 2. Consequently, in the following description, it will be considered that the length of a section of tube 1 (or of hole 7) corresponds to a direction substantially perpendicular to the long side (or longitudinal side) of the collector plate 2, while the width of a section of tube 1 (or hole 7) corresponds to a direction substantially perpendicular to the short side (or transverse side) of the plate collector 2.
  • each stamped part 7 is subdivided into at least two sub-stamps 8a and 8b each forming an imprint.
  • each stamped 6-i is in fact subdivided into three sub-stamps 8a to 8c.
  • stampings 6-i one starts from a blank whose peripheral edges 4 surrounding the flat central part 3 preferably have already a conformation forming the U-shaped groove 5. Then by stamping using a stamping tool comprising a multiplicity of parallel stamping heads each comprising as many aligned sub-parts as necessary (three in the example illustrated), the central part 3 of the blank is stamped in order to form the multiplicity stamping 6-i each comprising as many sub-stamps (or imprints) 8 aligned as each head of the stamping tool has sub-parts.
  • pre-collector or standard blank which can be transformed by punching into a large number of collector plates 2 adapted to receive tubes of different sections, respectively.
  • first type of collector 2 of which only the undercuts 8a have a hole 7 of length A1 (see FIG. 2) and of width B1 (see FIG. 5).
  • the hole 7 of the stamped 6-3 is made over the entire length of the three sub-stamps 8a to 8c (or indentations), so that said hole has a length A3 (see figures 2 and 4).
  • manifold plates 2 such as for example a first variant in which the holes are made on two consecutive sub-stamps 8a and 8b, in order to accommodate tubes of length A2 (see FIG. 2), or else a second variant in which two rows of holes of length A1 and A4 are produced using, on the one hand, the undercuts 8a, and on the other hand, the combination of consecutive undercuts 8b and 8c.
  • the invention also provides that the stampings 6-i, and therefore the undercuts 8, have a dimension in the direction YY perpendicular to the alignment direction XX of the undercuts, sufficient to allow the production of at least two different widths of holes (see Figure 5).
  • stampings 7 are wide enough to allow the production of holes of five different widths B. In the example illustrated in FIG. 5, only three different widths B1 to B3 have been materialized.
  • collectors provided with holes of a first section into collectors provided with holes of a second section greater in length and / or width than the first section.
  • the collector plate Once the collector plate has been produced, it only remains to introduce the tubes into the holes, then to join, by soldering or welding, the external wall of these tubes to the collector plate, at the punched imprints forming said holes.
  • the number of under-stamps (or footprints) of the same stamp can be much greater than two, and the width of the stamps can be adapted to allow more than five different widths of holes.
