Definitions

  • the invention relates to a manifold for a tube bundle heat exchanger, as well as a heat exchanger comprising this manifold and intended in particular for use in the automotive industry.
  • a collector, or tube plate, of such a heat exchanger can be constituted, in known manner, by a flat plate of rectangular shape, comprising holes in which the ends of the tubes are mounted for sealing, these holes being able to be defined by cylindrical tubular necks projecting from the plate, to improve the tightness of the mounting of the ends of the tubes.
  • the manifold can be made of plastic, which allows the ends of the sealing tubes to be mounted in the holes or collars of the manifold directly and without interposition of seals.
  • the water box which, conventionally, is mounted on the collector, is itself generally made of plastic material and is fixed in leaktight manner to the collector by welding.
  • This water box often includes an internal partition which extends perpendicularly to the collector and whose free edge must be applied to the sealing on the collector so as to divide the internal volume of the water box into two substantially sealed chambers.
  • the object of the invention is in particular to remedy this drawback and proposes for this purpose a collector for a tube bundle heat exchanger, this collector consisting of a plastic plate comprising mounting holes for the ends of the tubes, characterized in that the collector comprises, on its face external to the bundle of tubes, two parallel ribs defining between them a groove which extends between said holes.
  • This groove is intended to receive the free edge of the internal partition of the water box fixed to the collector.
  • the internal partition eventually breaks down, its free edge always remains maintained in the groove of the manifold, between the two parallel ribs thereof, which guarantees a substantially sealed separation between the two chambers of the water box.
  • the opposite face of the collector also comprises two ribs, which are parallel and identical to the ribs of the other face of the collector.
  • the collector can thus have a symmetrical structure, its two faces being identical to each other, which eliminates the risk of errors during the assembly of the heat exchanger.
  • said ribs when the holes are defined by tubular collars projecting from the collector, said ribs have, on each face of the collector, substantially the same height as the aforementioned collars and extend longitudinally on the collector .
  • the longitudinal orientation of the ribs can be defined as being perpendicular to the air flow which crosses the bundle when the exchanger is in service.
  • the ribs which are formed on the face of the collector opposite to the water box, and which have the same height as the collars, can come into contact with the end fin of the tube bundle and oppose an air flow, between the manifold and this end fin, in a transverse direction, that is to say perpendicular to the direction of said ribs.
  • the invention also relates to a tube bundle heat exchanger, comprising a collector of the aforementioned type and a water box fixed to the collector, this water box being formed with an internal partition which is perpendicular to the collector and one of which. edge is received in the groove formed by the aforementioned ribs of the collector.
  • This edge of the internal partition of the water box is advantageously fixed to sealing, for example by welding, in the groove of the collector.
  • the manifold 10, or tube plate, represented in FIGS. 1 and 2 consists of a flat molded plastic plate, with a rectangular outline, comprising cylindrical holes 12 arranged in rows and columns parallel to the edges of the plate 10 , and defined by tubular cylindrical collars 14 projecting on either side of the plate and thus having a height greater than the thickness of the plate.
  • the ends of the collars 14 can be chamfered internally, so that the ends of the holes 12 are slightly flared.
  • Each large face of the collector comprises two projecting parallel ribs 16, defining between them a groove 18 and extending longitudinally on the collector and for example along the median longitudinal axis 20 thereof.
  • the ribs 16 terminate in the vicinity of the ends of the manifold and therefore extend over most of the length thereof.
  • the height of the ribs 16 projecting from the plate 10 forming the manifold is substantially equal to that of the collars 14, preferably.
  • the ribs 16 formed on one side of the manifold 10 are strictly identical to those formed on the other side and symmetrical thereof, so that the clearance faces of the manifold are strictly identical one to the other.
  • these ribs 16 could be offset relative to the others from one side to the other of the collector.
  • This collector is intended for a heat exchanger shown partially in Figure 3, and which comprises a bundle of parallel tubes 22 which are provided with flat and parallel fins 24 crossed perpendicularly by the tubes 22 and fixed to the latter for example by crimping.
  • the ends of the tubes 22 are mounted in leaktight manner in the holes 12 of the manifold, for example using the elasticity of the plastic material constituting the manifold.
  • This known technique consists in introducing the ends of the tubes 22 into the holes of these manifolds, then in radially expanding the ends of the tubes by plastically deforming them, but without exceeding the elastic limit of the material of the collector, then by canceling the expansion forces.
  • radial ends of tubes Under the effect of their elasticity, the collars 14 defining the holes of the collector return to their initial shape, by radially contracting the parts 26 of tube lying between two parts 28 and 30 of tube which do not feel in contact with the collector and which remain radially expanded. This ensures simultaneous sealing between the ends of the tubes and the manifold, and the locking of the tubes in the holes of the manifold.
  • the end fin 24 of the tube bundle is applied over the entire length of the ribs 16 forced on the face of the manifold 10 facing said fins, l the end fin 24 is also applied, from place to place, on the ends of the collars 14 as shown in FIG. 3, when the ribs 16 and the collars 14 have the same height projecting from the collector 10.
  • a water box 32 of a conventional type, of which only one part is shown in Figure 3 is then mounted on the manifold 10 and fixed thereto by welding, for example by ultrasound, the water box 32 having for this purpose a peripheral flange 34 welded on the corresponding face of the manifold 10 to vicinity of the periphery of it.
  • the water box 32 is formed by molding with an internal partition 36 whose free edge 38 is received and welded in the groove 18 delimited by the ribs 16 of the corresponding face of the manifold 10.
  • the edge j8 of the internal partition 36 of the water box remains engaged between the ribs 16 of the manifold, and guarantees the sealing of the separation between the two chambers delimited in the water box via said internal partition 36.
  • the deformations of this partition 36 exert a stress at the weld between the edge 38 of this partition and the manifold, but are not large enough for the edge 38 to come completely out of the groove bounded by the ribs 16.
  • the latter can be mounted in one direction or the other between the water box 32 and the tube bundle, which prevents any risk of assembly-related error. of the exchanger.
