Definitions

  • the invention relates to a header plate for a heat exchanger, in particular for a heating and / or air conditioning installation of a motor vehicle.
  • collector plate of the type comprising a multiplicity of holes suitable for receiving the ends of the tubes of a bundle, as well as a peripheral groove capable of accommodating a peripheral heel of a fluid box, with the interposition of a seal.
  • the seal is produced in the form of a separate element made of rubber or the like, which is put in place during assembly of the heat exchanger to seal the connection. of the collector plate with the ends of the tubes, on the one hand, and with the fluid box, on the other hand.
  • This seal usually comprises a plate of shape adapted to that of the collector plate and having sleeves suitable for being interposed each between a hole in the collector plate and one end of the tube, as well as a peripheral bead suitable for being housed. in the peripheral groove of the collector plate and to be compressed by the peripheral heel of the fluid box.
  • the collector plate has collars which surround the holes and which each receive one end of the tube.
  • the sealing of the connection of the collector plate with each tube is ensured by the corresponding sleeve of the compressible seal, which is compressed between the end of the tube and the corresponding collar of the collector plate.
  • This compression generally results from a crimping operation applied to the end of the tube to deform it radially outwards.
  • the object of the invention is in particular to overcome the aforementioned drawbacks.
  • collector plate of the type defined in the introduction, in which the seal is overmolded on the collector plate to form with it a unitary assembly before assembly of the collector plate with the bundle tubes and with the box. fluid.
  • the seal is overmolded on the header plate, it is correctly positioned relative to the latter, which then guarantees sealing during assembly of the heat exchanger.
  • the thickness of the seal can be reduced to a minimum, or even reduced to zero in some cases. regions of the collector plate, resulting in a saving of material.
  • the overmolded seal extends over an entire face of the collector plate and has regions of different thicknesses.
  • the overmolded seal comprises an additional thickness in the form of a bead which extends in the peripheral groove. This bead is intended to be compressed by the heel of the fluid box.
  • each hole is bordered by a collar
  • the allowance surrounding the hole extends mainly on the side opposite the collar.
  • the excess thickness surrounding the hole extends mainly on the side of the fluid box.
  • the overmolded joint comprises an additional thickness in a region intended to receive one end of a partition forming part of the fluid box in order to delimit, in the latter, at least two sealed compartments, one compared to each other.
  • the sealing at the connection of the partition with the collector plate is effected by compression of the excess thickness of the joint.
  • the overmolded seal is advantageously formed from natural or synthetic rubber.
  • the invention in another aspect, relates to a heat exchanger comprising at least one collecting plate as defined above, mounted at one end of a bundle of tubes and provided with a fluid box.
  • FIGS. 1 and 2 show a manifold plate 10 fitted with an overmolded seal 12.
  • the collector plate is provided with a peripheral rim 20 which extends in a generally perpendicular direction at the bottom 14 and in a direction opposite to that of the collars 18.
  • the peripheral rim 20 is provided with teeth 22 suitable for being folded at a right angle, as will be seen below.
  • this bead 32 is formed by an additional thickness of the joint which has a thickness or height clearly greater than that of the regions 28 and 30.
  • the bead 32 occupies only a part of the section of the groove 24, that is to say that located furthest outside along the rim 20.
  • the joint has an additional thickness 34 located in the central part, this additional thickness 34 having a thickness greater than that of the regions 28 and 30, but less than that of the bead 32.
  • the extra thickness 34 ensures continuity with extra thicknesses 36 and 38 having a shape, at least partially annular, which surround the holes 16 ( Figures 1 and 2).
  • these extra thicknesses 36 and 38 each border a hole 16 and extend mainly on the side opposite the collars 18.
  • these extra thicknesses 36 and 38 have an internal diameter smaller than the internal diameter of the collets 18.
  • the seal 12 is molded onto the collector plate 10 by injection of a suitable sealing material, for example a natural or synthetic rubber, or another suitable elastomer.
  • a suitable sealing material for example a natural or synthetic rubber, or another suitable elastomer.
  • the material is injected between the collector plate 10 which acts as a mold and a counter mold (not shown).
  • the seal 12 is linked to the collecting plate 10 to form with it a unitary assembly ready to be used for the assembly of a heat exchanger.
  • the seal 12 is necessarily placed in a correct position relative to the collector plate 10.
  • the seal may have a thickness minimum, especially in regions 28 and 30, which results in a saving of material.
  • the collecting plate 10 thus equipped with the overmolded seal 12 then receives a multiplicity of tubes 40 (FIG. 3) each of which has one end 42 which is flared radially to ensure the compression of the seal, at the level of the extra thicknesses 36 and 38, and ensure tightness at the connection. Flaring of the tubes is carried out by crimping using a suitable tool, such as a pin inserted axially into the end of the tube.
  • the collecting plate 10 receives a fluid box 44, as can be seen in FIG. 4.
  • This fluid box 44 is produced by molding a plastic material and has a bottom wall 46 which terminates to a peripheral heel 48 suitable for being received in the groove 24 of the collector plate 10 to compress the bead 32 of the seal 12.
  • This heel 48 has a peripheral rib 50 intended to be received between the bead 32 and the parts 28 and 30, of lesser thickness, of the seal 12.
  • the heat exchanger thus produced can comprise another fluid box at the opposite end of the tubes 40.
  • these can consist of pin or U-shaped tubes, in which case the heat exchanger does not comprise only one fluid box.
  • the thickness of the seal is zero, which makes it possible to further increase the saving in material.
  • the heat exchanger thus produced can serve, for example, as a radiator for cooling a combustion engine. internal of a motor vehicle, or of a radiator for heating the passenger compartment of such a vehicle.
