Definitions

  • the invention relates to the field of heat exchangers and more particularly to the fixing between a heat exchange bundle and an inlet or outlet box for a heat transfer fluid.
  • An exchanger according to the preamble of claim 1 is known for example from document FR 2,422,921 .
  • a heat exchanger such as for example a charge air cooler, generally comprises a heat exchange bundle comprising tubes inside which circulates a first heat transfer fluid.
  • the heat exchanger also comprises input and output boxes of a second heat transfer fluid, here the supercharging air from a turbocharger.
  • the inlet and outlet boxes are fixed to the heat exchange bundle so that the second heat transfer fluid circulates between the tubes and can exchange heat energy with the first heat transfer fluid.
  • the boxes are generally attached to the heat exchange bundle by means of a collector.
  • This collector may for example be a metal strip on the periphery of the heat exchange bundle comprising crimping tabs which are folded by crimping tools on the box in order to crimp it.
  • One of the aims of the present invention is therefore to at least partially overcome the drawbacks of the prior art and to provide a heat exchanger whose attachment between a second fluid inlet or outlet box and a heat exchange tube. heat is improved.
  • the thinning of the thickness of the side wall at the level of the torsional portions is less than or equal to 20%.
  • the box is crimped by the collector over at least a quarter of its length between two corner corners of the heat exchange bundle.
  • the side wall is continuous over the entire periphery of the heat exchanger.
  • a seal is disposed between the bearing zone of the box and the base of the fixing device.
  • the seal is placed in a groove within the base of the fastener.
  • the box comprises, at the level of at least one corner corner of the heat exchange bundle, an abutment bearing against the edge of the non-folded portion and a perpendicular foot. said stop, said foot coming to compress the seal.
  • the collector comes from material with the heat exchange bundle.
  • the collector is an element fixed on the periphery of the heat exchange bundle.
  • the heat exchange bundle 3 generally has a parallelepiped shape, a first collector 7 following the periphery of a face of said heat exchange bundle 3 and a second collector 7 following the periphery of the opposite face.
  • the collector 7 can be made of material with the heat exchange bundle 3 or it can be an element fixed on the periphery of the heat beam 3, for example by brazing.
  • the manifold 7 comprises a base 71 on which is intended to rest a bearing zone 57 of the box 5a, 5b.
  • the box 5a, 5b comprises in turn at least one shoulder 51 facing outwardly of said box 5a, 5b. This shoulder 51 is disposed at its bearing zone 57.
  • the manifold 7 also has a side wall 75 which is folded over the shoulder 51 to secure the box 5a, 5b by crimping.
  • the heat exchanger 1 comprises at least one minus two portions folded 77 on the shoulder 51, preferably on opposite sides of the same face.
  • a continuous folded portion 77 is present on each side of the heat exchanger 1.
  • a seal 9 may be placed between the bearing zone 57 of the box 5a, 5b and the base 71 of the collector 7.
  • the seal 9 is compressed between the bearing zone 57 and the base 71 as shown in FIG. figure 2 .
  • the seal 9 may in particular be arranged in a groove within the base 71 of the manifold 7. It is nevertheless entirely possible to imagine that the seal 9 can be integrated directly into the bearing zone. 57.
  • the side wall 75 of the manifold 7 continuously follows the contour of an angle of the heat exchange bundle 7. This angle tracking by the side wall 75 is illustrated in more detail on the figure 3 .
  • the sidewall 75 comprises, on either side of the corner corner of the heat exchange bundle 3, a folded portion 77 and, at the corner corner of the heat exchange bundle 3, a non-folded portion 79.
  • the folded portions 77 are connected continuously to the non-folded portion 79 by a torsion portion 78 of the side wall 75.
  • the thinning of the thickness of the side wall 75 of the collector 7 at the level of the torsion portions 78 is preferably less than or equal to 20%.
  • L corresponds to the length between the non-folded wall 79 and the folded portion 77 in the fold axis of the portion 77.
  • P corresponds to the crimping depth, that is to say the distance between the inside of the wall 79 and the end of the folded portion 77, in the crimping direction of the folded portion 77.
  • H corresponds to the height of the non-folded portion 79, that is to say the distance between the plane formed by the shoulder 51 and the top of the non-folded portion 79.
  • the values a1, a2, b1 and b2 are constants obtained by tests and tests as a function of different thinning of the thickness of the collector 7. These constants are indicated in the following table: Slimming% a1 b1 a2 b2 3.3 -0.36 3.89 4.02 -4.40 6.7 -0.25 2.68 2.77 -3.03 10.0 -0.20 2.13 2.20 -2.41 13.3 -0.17 1.79 1.85 -2.03 16.7 -0.14 1.55 1.61 -1.76 20.0 -0.13 1.37 1.42 -1.56 23.3 -0.11 1.23 1.27 -1.39 26.7 -0.10 1.11 1.15 -1.26 30.0 -0.09 1.01 1.04 -1.14 33.3 -0.08 0.92 0.95 -1.04
  • the latter is crimped by the collector 7 over at least a quarter of its length between two corner angles of the heat exchange bundle 3.
  • the manifold 7 has a side wall 75 continuous over the entire periphery of the heat exchanger 1.
  • the manifold 7 has no crimping tabs and instead has folded portions 79 on each side of the heat exchanger 1, the folded portions 79 connecting the portions in torsion 79 at the corners.
  • the collector 7 is more resistant to stress, for example related to vibrations, since the latter are distributed over the entire length of the sides of the heat exchanger 1 and over the entire length of the side wall 75.
  • the box 5a, 5b may comprise, at the level of at least one corner corner of the heat exchange bundle 3, a stop 50 coming to bear against the edge of the non-folded portion 79 at a corner of angle of the heat exchanger 1.
  • the box 5a, 5b may also comprise a foot 52 perpendicular to said stop 50.
  • the stop 20 comes into contact with the edge of the portion not folded 79 and the foot 52 compresses the seal 9.
  • the length of the foot 52 determines the compression of the seal 9 on the periphery of said heat exchanger 1.
  • the heat exchanger 1 according to the present invention makes it possible, owing to the particular conformation of the collector 7, in particular at the corner corners, to have better resistance to stresses and therefore a better durability of the fixing between the heat exchange bundle 3 and the box 5a, 5b.
