Definitions

  • the present invention relates to heat exchangers comprising a bundle of tubes engaged in header plates which are intended to be covered by water boxes assembled in a removable manner, that is to say fixed on the periphery of each plate. collector with interposition of a deformable joint.
  • British patent 699,032 has described embodiments in which the peripheral edge of the water box is crimped onto a flexible joint by forming a hollow rib which is intended to increase the rigidity of the crimped edge. .
  • This apparently satisfactory arrangement requires the implementation of a complex tool to form the hollow rib inside which is placed the flexible joint.
  • the Applicant has itself described in its French patent 74 16284 an embodiment in which the peripheral edge of the water box has a rounded conformation to increase its rigidity and, in this case, the edge of the collector plate is crimped on the raised end of the peripheral edge of the water box.
  • the heat exchanger comprising a bundle of tubes opening into collector plates delimiting, at their periphery, a groove externally bordered by a rising edge, a seal being arranged in the bottom of the groove for be clamped by the underside of a rim formed by a water box maintained either by crimping parts extending the rising edge of the collecting plate, or by an attached pliers
  • the water box is thin-walled and in that a bar is interposed between the top of the edge of this water box and the crimping parts of the collector plate or of the attached pliers.
  • Fig. 1 is a partial perspective, partially cut away, of a heat exchanger applying the invention.
  • Fig. 2 is a partial perspective similar to FIG. 1 of a variant.
  • Fig. 3 is a perspective of a particular organ used for the implementation of the invention.
  • Fig. 4 is a partial section illustrating a variant of the invention
  • Fig. 5 is a section illustrating a development of the invention.
  • Fig. 6 is a section taken along line VI-VI of FIG. 5.
  • 1 denotes the circulation tubes of a heat exchanger, in particular of a cooling exchanger of the kind used in motor vehicles. These tubes are connected together in the usual way by dissipators 2 constituted, for example, by corrugated strips or by fins.
  • the ends of the tubes 1 are engaged in collecting plates 3 which have, at their periphery, a groove 4 and an external rising edge 5.
  • the collecting plates 3 which the exchanger comprises are made of a metal or an alloy compatible with the metal or alloy of the tubes 1 and of the dissipators 2 and all of these parts are joined together by brazing or by another means.
  • the collectors 3 there is used to cover the collectors 3 a water box 6 with a thin wall which is advantageously made of metal, in particular by stamping.
  • the water box comprises, in a known manner, pipes, bases and other conduits usual in the art.
  • the water box has at its base a peripheral rim 7 of width corresponding to that of the groove 4 of the collector plate 3 and this rim is extended, in particular to stiffen it, by a rising edge 8.
  • the bar 10 prefferably to form a bead 11 covering the top of the rising edge 8 of the box.
  • a next operation consists in putting in place a clamp 12, well known in itself, which wraps the underside of the part of the collecting plate forming the groove 4 and which extends along the rising edge 5 and of which tabs 13 are crimped onto the top of the bar 10.
  • the strip extends over the four sides of the collector plate.
  • the top 10a of the bar is preferably located above the edge of the collector so that the fold 13a of the legs does not generate a line of fatigue.
  • collector plates are most often of uniform width, it is advantageous, as illustrated in FIG. 3, to produce by molding bars 10 having the shape of a rectangular frame whose dimensions correspond to those of the largest collecting plate that can be used and these bars in the shape of rectangular frame are then cut to length, as illustrated for example by the section lines 14 shown in FIG. 3. It is obviously possible, if desired, to form bars in the form of a rectangular frame for each type of exchanger, similarly, it would not go beyond the scope of the invention to manufacture half-frames whose sides would then be cut to length or by using sections of bars which would be arranged in the four sides of the groove of each collector plate.
  • Fig. 2 illustrates a slight variant according to which the clamp 12 is not used.
  • the rising edge 5 of the collecting plate which is provided with lugs 13 crimped on the top of the bar 10.
  • the edge lOb at least of the bar is rounded so that the bending of the legs 13 is carried out in good conditions.
  • Fig. 4 illustrates a simplified embodiment according to which the water box 6 does not have a rising edge 8 as in the previous embodiments, but is only surrounded by a flat rim 7a.
  • a bar 10a place as above on the top of the rim a bar 10a whose width corresponds to that of the rim 7a and the lugs 13a of the collector plate 3 are crimped as illustrated in FIG. 2 on the top of the bar.
  • FIGs. 5 and 6 illustrate a development of the invention which is implemented in the embodiment described above with reference to FIG. 2 but which can obviously apply to other embodiments.
  • notches with a curved bottom are formed in the bars and the tabs 13 are folded back in the notches and deformed corresponding to the bottom, which considerably increases the stiffness of the tabs.
  • the bar which is made of hard material supports the forces due to crimping and distributes these forces on the rim 7 or 7a of the water box, rim which is thus applied under uniform pressure on the seal.
  • the water boxes can be made of synthetic material while having a thin wall normally deformable under the influence of the force usually applied by the legs 13 if the bars 10 were not used. It is thus possible to manufacture water boxes at a much lower cost price than that of molded plastic boxes, the thickness of which must prevent any deformation of the part applied to the seal 9 by the tabs 13.
