Definitions

  • the present invention relates to a heat exchanger, in particular for motor vehicles.
  • DE-A-24 18 132 discloses a heat exchanger comprising a bundle of finned tubes on which is fixedly fixed on one of its lateral edges, a plate or cross-member allowing the bundle to be suspended or fixed to the vehicle body.
  • a heat exchanger comprising at least one water box disposed at one end of a bundle of finned tubes traversed by a first fluid and an envelope traversed by a second fluid and surrounding said bundle.
  • the exchanger thus formed is part of an installation used for cooling the air leaving a turbo-compressor and intended for supercharging the heat engine.
  • the envelope may be a casing which generally provides a housing open at at least one end and into which the bundle is inserted by sliding, in the manner of a drawer.
  • the casing is then closed by a cover so as to provide an enclosure, which, in the case of cooling of the charge air, comprises an inlet manifold and an outlet manifold of said air so that it arrives by the inlet tubing passes through the bundle that comprises the exchanger and can be cooled there.
  • a bundle of tubes is provided. fins, provided with two water boxes and comprising hollow cylindrical sheaths of length slightly greater than the thickness of the bundle and traversing it right through, being placed from place to place along said bundle and parallel to a lateral face of the exchanger.
  • the bundle is then slid, like a drawer, into a casing with a single open face to be assembled therewith, the ends of the sleeves coming into contact with the internal faces of the walls of said casing by forming spacers.
  • These walls include, in accordance with the cylindrical sleeves, bores allowing the introduction of screws.
  • the beam is immobilized in translation in the casing by the sleeves and locked in the latter by the screws and on the other hand the possible deformations of said walls are prevented by the same screws which form tie rods.
  • the hollow cylindrical sleeves must be of large diameter in order to be able to resist the tightening force exerted by the screw and the nut.
  • the placement of these sleeves requires on the one hand to occupy a location requiring the removal of a tube from the bundle and on the other hand to provide bores for receiving them through said bundle, these bores requiring to cut fins along their length.
  • the present invention aims to remedy these drawbacks by simplifying and facilitating assembly of the bundle with the envelope or the casing containing it while retaining the performance of said exchanger.
  • a heat exchanger in particular for motor vehicles, comprising at least one water box disposed at one end of a bundle of finned tubes traversed by a first fluid and an envelope, such as a limited casing. by walls surrounding said bundle and traversed by a second fluid, exchanger in which two faces of the bundle are adjacent to walls of the casing braced between them by assembly means positioning the bundle and carried by the latter, the exchanger is characterized in that the assembly means consist of sliding mutual engagement means carried respectively by the beam and by at least one of the walls of the casing, forming means for bracing and holding said walls.
  • the means of mutual engagement consist of at least one assembly of the tenon-mortise type.
  • FIGS 1 and 2 are shown a heat exchanger comprising a bundle 6 of tubes 8 with fins 7 and an envelope 2 containing it.
  • the bundle 6 is provided with at least one water box 3 comprising inlet pipes 4 and outlet pipes 5 for the heat transfer fluid.
  • the latter is slid, like a drawer, into the casing 2 here a casing 9 providing a housing 10 open at one end 11.
  • This casing is of generally parallelepipedal shape delimited by two large parallel and opposite walls 12, 13, two small opposite walls and inclined towards one another 14, 15 and a bottom 16.
  • the open end 11 is closed, after introduction of the bundle 6 into the housing 10, by a cover 17 carrying inlet pipes 18 and outlet pipes 19 for the fluid to be cooled.
  • the assembly thus formed constitutes a device for cooling the air leaving a tubocompressor intended for supercharging the heat engine of a motor vehicle.
  • the present invention proposes, as better visible to Figure 3, to remedy this drawback.
  • the bundle 6 of finned tubes is linked to the casing 9 by means of mutual engagement.
  • At least one front face of the beams 6, here both, comprises, over the entire length and parallel to a lateral face of said beam, at least one groove 21 or mortise, here in the form of a dovetail, practiced on the edge of the fins 7.
  • an internal face 22 of at least one wall, here the two walls 12, 13, has at least one projection 23 with a tenon, of shape and arrangement complementary to those of the mortise 21 therefore in shape dovetail arranged opposite the mortise over the entire length of the wall considered.
  • the harness 6 is assembled with the casing 9 as follows:
  • the bundle 6 is presented opposite the open end 11 of the casing 9 in such a way that the mortises 21 of the bundle 6 are arranged in concordance with the tenons 23.
  • the bundle is then introduced into the housing 10 by sliding the mortises 21 on the tenons 23 by mutual engagement until the complete penetration of said beam in said housing.
  • the cover 17 is attached to the open end 11 for closing thereof.
  • the beam is blocked in a first direction by the bottom 16 and the cover 17 and in the other two directions by the tenon-mortise assembly with complementary shapes.
  • This assembly also makes it possible to avoid deformation of the walls 12, 13 of the casing 9, when the charge air is admitted, by creating a rigid connection between the front faces of the bundle 6 and the internal face of the walls 12 , 13, while allowing possible disassembly of the bundle 6 from the housing 10.
  • the bundle 6 comprises at least one tenon 24, here in the form of a dovetail, disposed on at least one front face of said bundle, here the two faces.
  • the tenon 24 can be part of either a projection each coming from the front edge of the fins 7 of the bundle 6 so as to form a longitudinal tenon of length equal to the length of the bundle and being parallel to a lateral face of the bundle 6, or an installation, during the development of the heat exchanger bundle, of at least one fin of greater thickness than the fins 7 and which has a projection forming a pin 24.
  • This fin can be arranged, at regular intervals , in the stacking of fins 7, such as for example all twenty or thirty fins 7. Thus in practice it is sufficient at least one fin of greater thickness disposed in the middle of said beam.
  • the walls 12, 13 of the casing 9 comprise, from their internal faces 22 and beyond their external faces, at least one groove 25 or mortise, of shape and arrangement complementary to those of the tenon 24, that is ie in the form of a dovetail, located in concordance with the tenon 24 and this, over the entire length of the wall considered.
  • the assembly of the bundle 6 with the casing 9 is carried out in the same manner as that described for FIG. 3.
  • Figure 5 shows another alternative embodiment of the assembly according to the invention.
  • At least one tenon 26 is attached to at least one front face of the bundle 6.
  • the latter is formed by a plate 50 which has a general T shape whose horizontal bar of the T is formed by two branches 27 , 28 parallel to the front face of the bundle and whose vertical bar is hollowed out from the intersection with the horizontal bar so as to leave one end open and whose base of said vertical bar forms a wall 29 parallel to said front face by being applied against it and connecting the branches 27, 28 respectively by perpendicular walls 30, 30 ⁇ to distance from the wall 29.
  • This plate 50 attached to a front face of the bundle along its length and parallel to a lateral face, is fixed to the bundle by any suitable means such as brazing for example.
  • each stud 26 through the heat exchanger bundle by any appropriate means such as for example a flat bar 31 consisting of a rectangular plate 32 which can pass into the space available between two fins and comprising, at one end, an enlarged part forming a support head 33.
  • a flat bar 31 consisting of a rectangular plate 32 which can pass into the space available between two fins and comprising, at one end, an enlarged part forming a support head 33.
  • the wall (s) 12, 13 carry at least one recess 34 or mortise of shape and arrangement complementary to that of the stud 26, that is to say in the shape of a T, erecting from their internal faces 22 projecting towards the outside of said walls and the horizontal bar of the T of which is constituted by a longitudinal groove 35 and the vertical bar by a longitudinal groove 36.
  • the assembly of the bundle 6 in the casing 9 is identical to that described above.
  • the casing 9 can be in two separate parts, each open at one end. So after having introduced the bundle of finned tubes into the first part by sliding the mortises or tenons carried by the beam along the tenons or mortises of said first part, it suffices to slide the tenons or mortises of the second part of the casing along the mortises or tenons carried by the beam.
  • the front face of the bundle and the internal face of the wall each carry an identical tenon or a mortise and that there is provided an intermediate connecting part carrying forms of mutual engagement with the forms carried. by said front face and said internal face, and that the latter is slid either in the tenons or in the mortises so as to ensure the connection between the wall and the bundle.
