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 collars 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 the free edge of which must be applied in leaktightness to the collector so as to divide the internal volume of the water box into two separate chambers in a substantially sealed manner.
  • 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 deforms, 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 invention provides a manifold for a heat exchanger, of the type described in the aforementioned document, which also has additional advantages.
  • the manifold for a tube bundle heat exchanger is characterized in that the opposite face of the manifold comprises two ribs parallel and identical to the ribs on the other face, the holes of said plate being defined by tubular collars projecting on each face of the plate, the ribs and the collars being identical and symmetrical on the two faces 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.
  • the ribs which are formed on the face of the collector opposite the water box come to bear on the end fin of the bundle of tubes by forming a barrier opposing the circulation. air between the manifold and the beam end fin, in a direction perpendicular to that of the ribs.
  • 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 whose 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 parallel ribs 16 projecting, 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 two faces of the manifold are strictly identical one to the other.
  • these ribs 16 could be offset from one another from one face to the other of the manifold.
  • 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 the collectors, then in radially expanding the ends of the tubes by deforming them plastically, but without exceeding the elastic limit of the material of the collector, then by canceling the forces of expansion radial ends of tubes.
  • 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 are not 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 formed on the face of the manifold 10 facing towards 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 a part is shown in FIG. 3, is then mounted on the collector 10 and fixed to the latter by welding, for example by ultrasound, the water box 32 having at this indeed a peripheral rim 34 welded on the corresponding face of the collector 10 in the vicinity of the periphery thereof.
  • 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 38 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 by 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 collector, but are not large enough for this 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 error during assembly. of the exchanger.
