Definitions

  • the invention relates to a heat exchange module, especially for a motor vehicle, consisting of several exchangers having common fins.
  • It relates more particularly to a heat exchange module comprising at least two heat exchangers, each exchanger consisting of a beam interposed between two manifolds, the bundle being formed of fluid circulation tubes connected to the collector boxes and which pass through cooling fins common to at least two exchangers of the module.
  • the heat exchangers for motor vehicles are generally in the form of a bundle of fluid circulation tubes and heat exchange fins with the external medium.
  • the beam is interposed between two manifolds that distribute the fluid in the circulation tubes.
  • the exchanger has a single header divided into an inlet section and an outlet section.
  • the secondary exchanger is most often an engine cooler air cooler, an air conditioning condenser or an oil cooler.
  • the exchangers are assembled in a single operation by soldering.
  • the fins consist of corrugated dividers arranged between the tubes and parallel to these.
  • the constituent parts of the exchanger are assembled exclusively by mechanical means such as crimping.
  • This type of exchanger comprises thin fins and flat, arranged perpendicular to the tubes and traversed by them.
  • Mechanically assembled exchangers have several advantages. They are compact, they offer ease of mounting collectors, the spacings between the ends of the tubes being accurate. Their fins being finer than those of brazed exchangers, they are more numerous and allow a better heat exchange. However, they have the disadvantage of requiring assembly operations expensive in time and tooling. In particular, the assembly of the secondary heat exchanger (s) on the main exchanger must be obtained by particular mechanical means which adversely affect the compactness of the module.
  • the document EP 0881450 describes a heat exchange module comprising two exchangers having common flat fins brazed to the tubes of the exchangers.
  • this module remains a difficult and expensive assembly, the tubes being inserted axially into the fins.
  • JP 03128167 discloses an exchanger provided with flat fins. These consist of two half-wings laterally clasping the tubes. This avoids axial insertion of the tubes into the fins.
  • the present invention relates to a heat exchange module which, while retaining the advantages of mechanically assembled heat exchangers, provides ease of assembly of the heat exchangers between them and allows for a compact heat exchange module.
  • the tubes and the fins are joined by brazing and that the fins have the shape of an elongated rectangle having two elongate sides and two short sides, the fins having, on at least one of the elongate sides, the tubes receiving cutouts in which the circulation tubes of at least one of the exchangers are introduced.
  • the assembly of the module is particularly simplified in that the tubes can be slid laterally into the receiving cutouts of the fin tubes, before being secured to these fins by brazing.
  • the invention is preferably applied to heat exchange modules comprising metal manifolds, particularly of aluminum.
  • the tube plate and the lid being metallic, the lid, the tube plate and the bundle are assembled by soldering in a single operation.
  • This variant embodiment therefore requires a minimum of assembly operations.
  • the invention also applies to the case where the beam alone is brazed.
  • the tube plates are conventionally fixed to the tubes by flaring the ends of the latter.
  • the lid of the manifold made for example of plastic material, will be assembled only mechanically, for example by crimping of the legs of the manifold.
  • This variant has the advantage of removing a number of mechanical assembly operations of the tube plate on the ends of the tubes of the bundle.
  • the tubes receiving cutouts exist only on one of the two elongated sides of the fins.
  • the heat exchange module comprises at least two exchangers, two or more tubes are introduced successively into each of the receiving cutouts made in the fin.
  • the blank can thus contain two, three or more tubes.
  • the fin has recesses for receiving the tubes on each of the two elongate sides.
  • the tubes of the exchangers are distributed on the two elongated sides of the fins.
  • the tubes of an exchanger are introduced into the receiving cutouts of the tubes of one of the elongated sides, while the tubes of fluid flow are introduced into the receiving cutouts of the tubes on the other elongated side.
  • the heat exchange module comprises more than two exchangers, for example three, the tubes of two exchangers will be introduced into the receiving cutouts of the tubes of one of the elongate sides, and the tubes of the third exchanger into the cutouts of receiving the tubes from the other elongated side.
  • the receiving cutouts of the tubes may have a constant width over their entire length.
  • the receiving cutouts of the tubes have a stepped profile which widens from the bottom of the cutout to the inlet of the cutout.
  • This embodiment is particularly suitable in the case where the exchangers have fluid circulation tubes of different thicknesses.
  • the stepped profile of the tube receiving cutout makes it possible to adapt the width of the cut to the thickness of the tubes of each exchanger.
  • each receiving cutout of a tube comprises a thermal insulation notch located between the tubes of the exchangers.
  • This notch is intended to avoid, as far as possible, the establishment of a thermal bridge between the portion of the fins corresponding to an exchanger and the portion of the fins corresponding to the adjacent exchanger.
  • the fins and / or the tubes are covered with a solder plating.
  • the short sides of the fins are folded and secured to the beam by brazing.
  • the invention furthermore relates to a method for manufacturing a heat exchange module comprising at least two heat exchangers, each exchanger consisting of a beam interposed between two collecting boxes, the beam being formed of tubes of circulation of fluid connected to the manifolds, and which passes through cooling fins common to the exchangers of the module, the fins having the shape of an elongated rectangle having two elongated sides and two short sides.
  • the lid, the tube plate and the bundle are assembled by brazing in a single operation. If all the tube plates and covers are metallic, for example aluminum, the module is assembled in a single operation by brazing and all the mechanical assembly operations are removed.
  • the tube plate and the bundle can be assembled by brazing into one only operation.

On the elongated side 16, there are cutouts 22 for receiving the tubes 5 of the exchanger 1 and the elongated side 18 of the cutouts 24 for receiving the tubes 10 of the exchanger 2. As can be seen in Figure 3, the cutouts 22 and 24 have a shape corresponding to that of the tubes. Their width is designed in such a way that the tubes can be introduced by just sliding. The pitch of the cutouts 22 and 24 is equal to that of the tubes 5 and 10.
