Definitions

  • the present invention relates to a new method for crimping a water box into a header plate of a heat exchanger so that the water box compresses a deformable seal which must ensure a perfect seal between the header plate and the water box .
  • the crimping of the water box is most often carried out by means of tabs which project from the peripheral rising edge of the collecting plate, these tabs being folded over a projecting rim which the water box has.
  • FR-A-2 050 306 a water box-collector plate connection by providing stapling members projecting into the peripheral edge of the water box and by engaging these stapling members in lights on the rising edge of the collector plate. Similar arrangements have also been described in FR-A-2 443 602.
  • FR-A-2 524 977 describes in one embodiment the fact of forming stampings near the upper end of lugs which extend the rising edge of the collector plate so that these stampings form stops for the peripheral edge of the water box.
  • This arrangement requires that the stampings be formed after the water box has been put in place and while it is tightened on the joint which must seal between it and the collector plate.
  • the tools required are complicated because it is also necessary to provide a leg retaining part when the stamping tool is working and the space for placing a retaining tool is so small that it is practically impossible to produce such a tool.
  • the present invention relates to an embodiment which makes it possible to obtain the same advantageous results as those obtained by the introduction of protruding stapling members of the water box into the openings of the rising edge of the collecting plate while allowing easy placement of the water box, regardless of the nature of the metal which constitutes the collecting plate.
  • the method for crimping a header plate of a heat exchanger on a water box in which there is provided a peripheral rising edge to fit an extra thickness delimited by the water box and a flexible deformable seal between the water box and a groove formed by the collector plate is characterized in that protruding undulations are formed above a line of least resistance in the edge, these undulations leaving segments free between them, in that 'the rising edge is placed in a tool having crimping walls whose spacing corresponds to the spacing of the external face of the different plane sides of the rising edges of the collector plate, so that it is placed in the groove of the collector plate the deformable seal, in that the water box is placed so that a heel which it presents bears on said seal, and in that one exerts pressure on the water box causing the seal is first deformed then that the projecting undulations and the segments placed between them are then folded down towards an edge of the water box at the same time as the deformable seal continues to be maintained under pressure.
  • 1 denotes a water box of a heat exchanger.
  • the box 1 is made of molded material, for example synthetic material or metal, and delimits, at its lower part, an extra thickness 2 forming on its bottom a heel 3 and on its top a rim 4.
  • the drawing shows that the extra thickness 2 is formed over the entire periphery of the water box.
  • the water box is intended to cover a metal collecting plate 5 into which open tubes 6 which are tightly connected thereto and between which are, for example, heat sinks 7.
  • the collecting plate defines a groove over its entire periphery or gutter 8.
  • the peripheral rising edge 9 of the collector plate has, substantially at the position which the rim 4 of the water box must occupy, holes or openings 10 intended to create a line of least resistance designated by 11 in the drawing.
  • Corrugations 12 are formed above the line of least resistance 11, these corrugations leaving free between them segments 13 which lie in the same vertical plane as that passing through the internal face of the rising edge 9.
  • Figs. 2 and 3 thus show that the corrugations 12 leave the groove 8 formed by the collector plate completely free, which allows an easy installation of the additional thickness 2 of the water box 1 in the groove 8 after having disposed there a flexible seal. deformable 14.
  • the existence of the corrugations 12 has the effect of stiffening the upper part of the rising edge 9 above the line of least resistance 11.
  • the height of crimp walls 18 is greater than the height of the rising edge 9 of the collector plate.
  • the collector plate to which the tubes 6 and dissipators 7 are fixed is engaged in the tool 15 until the corrugations 12 abut against the top 19 of the tool.
  • the holes or openings 10 delimiting the line 11 of least resistance cover the lateral edge of the rim 4 which is thus partially at least embedded while the segments 13 are folded over the top of said rim 4.
  • Figs. 4 and 8 illustrate a slight variant according to which notches 20 are formed in the rim 4 to delimit, between them, teeth 21 which coincide with the holes 10 of the collector plate. It is advantageous that the holes 10 have a diameter or a width if they are oblong, rectangular or trapezoidal (FIG. 8) greater than the width of the teeth 21 to compensate for the manufacturing tolerances existing between the water box and the collector plate .
  • the line of least resistance 11. is then situated substantially at the level of the base of the teeth 21.
  • the slots or notches 22 can be replaced by corrugations which are tightened at the time of crimping.
  • the line of least resistance can be delimited other than by lights; it is possible that it is formed by a thinned part, for example a continuous or discontinuous groove of the collector plate. It is also possible that the lights are connected by a part of less resistance, particularly when the water box forms teeth 21.
