Definitions

  • the invention relates to collector plates, or collectors, for heat exchangers, especially for vehicles automotive, especially those that include in a central part at least one row of holes parallels suitable for receiving tube ends.
  • Parallel holes are generally made in stamped, by punching.
  • a second punching step holes are made, one per stamped, and whose shapes and dimensions are adapted to the cross section of tubes to be introduced.
  • the stamping carried out in the first stage cannot correspond to a single type of tube whose dimensions are chosen.
  • one of the objects of the invention is to provide a collector which does not have the disadvantage of prior art collectors.
  • the invention provides a blank according to claim 1.
  • a single stamping tool allows make stampings whose aligned footprints allow making holes of different sections.
  • a single footprint will be sufficient to make a hole small dimensions, while two footprints aligned and consecutive will allow for example the realization of a larger hole, or two holes smaller dimensions.
  • the invention also provides a method according to claims 5 and 6.
  • a method according to the preamble of claim 5 is known from FR-A-2,538,526.
  • a heat exchanger usually includes one or two fluid boxes (not shown) into which open 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 part central called “bottom”, and on the other hand, over the whole periphery of its central part, a peripheral edge shaped 4, for example by folding, which defines a groove 5 in U arranged to accommodate a peripheral heel made on the periphery of the wall forming the fluid box.
  • Each stamped 6-i has a hole 7 (in the example illustrated in figure 1 only stamped 6-3 is provided with a hole) likely to receive a tube end 1.
  • the stampings are preferably intended to accommodate tubes oblong (also called flat tubes) with a minor axis B (or width), and major axis A (or length).
  • tubes are positioned in the plate manifold 2 parallel to the short side, or transverse side, of the collector plate 2. Consequently, in the following the description, we will consider 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 in a direction substantially perpendicular to the short side (or transverse side) of the collector plate 2.
  • each stamp 6 is subdivided into at minus two undercuts 8a and 8b each forming a footprint.
  • each deep-drawn 6-i is actually subdivided into three deep-drawn 8a at 8c.
  • the peripheral edges 4 surrounding the flat central part 3 preferably already have a conformation forming the U-shaped groove 5.
  • stamping using a stamping tool with a multiplicity of heads parallel stamping each comprising as many sub-parts aligned as necessary we just stamp the central part 3 the blank to form the multiplicity of 6-i stamps each comprising as many undercuts (or imprints) 8 aligned that each head of the stamping tool has of subparts.
  • 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.
  • the hole 7 of stamped 6-3 is made over the entire length of the three undercuts 8a to 8c (or imprints), so that said hole has a length A3 (see Figures 2 and 4).
  • the invention also provides that the stamped 6-i, and therefore the pressed stamps 8, have a dimension in the Y-Y direction perpendicular to the alignment direction X-X of the undercuts, sufficient to allow the realization of at least two widths of different holes (see Figure 5).
  • stampings 6 are wide enough to allow the making holes of five different widths B.
  • the number of undercuts (or footprints) of the same stamped may be much greater than two, and the width of the stampings can be adapted to allow more than five different hole widths.
