Definitions

  • the invention relates to a heat exchanger, in particular for a motor vehicle, of the tube bundle and metal manifold type, in which the ends of the bundle tubes are sealingly mounted in the holes of the manifold, on which is fixed a water.
  • These heat exchangers are intended in particular to form cooling radiators for the thermal engines of motor vehicles.
  • Such a heat exchanger is assembled without welding, the sealing of the bundle tubes with the collector being ensured by an elastomer seal.
  • Such relative movements can be caused in particular under the effect of pressure and mechanical stresses transmitted to the water boxes by the fixing points of the heat exchanger.
  • This pivoting or torsion phenomenon is particularly critical when the bundle has only one row of tubes.
  • French Patent No 84 02964 published under No 2 560 368, describes a heat exchanger which comprises immobilization means cooperating with fins or the like carried by the tubes of the bundle to oppose relative displacement, in particular by pivoting or twisting, of the beam relative to the manifold-water box assembly.
  • these immobilization means are constituted by tabs molded with the water box, which requires to provide specific water boxes.
  • the invention provides another solution.
  • the immobilization means comprise immobilization tabs, folded and formed in one piece with the metal manifold and extending parallel to the direction of the tubes so as to bear against the edges of a certain number of fins of the beam.
  • immobilization tabs are therefore produced in one piece with the collector, the assembly being able to be easily manufactured by conventional operations of cutting, stamping and bending of a metal sheet.
  • the heat exchanger comprises two folded tabs provided at the longitudinal ends of the manifold so as to receive the longitudinal ends of a certain number of fins of the bundle.
  • the folded tabs have, in section, substantially the shape of a U.
  • each of the legs comprises a generally rectangular core connected to the collector by a tongue and two wings folded at right angles to the core, the core coming to bear against an end face of the bundle and the two wings coming to bear against two longitudinal faces of the beam.
  • the two U-shaped legs thus cover the bundle at its two longitudinal ends.
  • the folded legs have slightly open edges in order to facilitate the mounting of the bundle and not to injure the fins.
  • the collector and the immobilization tabs are formed from a sheet blank previously cut and stamped.
  • the tabs are formed initially in the plane of the sheet blank and then folded.
  • the heat exchanger partially shown in FIGS. 1 to 3 comprises a bundle 10 formed of a single row of aligned tubes 12 passing through a multiplicity of plane fins 14 parallel to each other and extending perpendicular to the direction of the tubes 12.
  • a manifold 18 also called “tube plate” or “plate with holes” comprising at its periphery crimping lugs 20 which are folded over the peripheral rim 22 of a water box 24 of the conventional type.
  • the holes 16 of the manifold 18 ( Figure 3) have substantially the shape of ellipses whose small axes are aligned and directed in the direction of the row R of the tubes.
  • Each of the holes 16 is surrounded by a collar 26 ( Figures 1 and 3).
  • an elastomer sheet 27 (FIG. 1) which covers one face of the manifold 18 and which includes collars (not shown) clamped between the ends of the tubes 12 and the collars 26, and this in a manner known per se.
  • the collector 18 is formed from a blank of a metal sheet.
  • the manifold 18 proper has a generally rectangular shape and has two longitudinal edges 30 which form the long sides of the rectangle and extend parallel to an axis XX corresponding to the direction of the row R and at the same time constituting an axis of symmetry.
  • the manifold 18 comprises two longitudinal ends 32 which constitute the short sides of the rectangle.
  • the crimping lugs 20 are formed essentially along each of the longitudinal edges 30.
  • the collector 18 further comprises a crimping lug 34 formed by a puncture in the sheet at each of the longitudinal ends 32 ( Figures 1 to 3).
  • the crimping lugs 20 and the crimping lugs 34 are adapted to be folded against the peripheral edge 22 of the water box 24, and this in a manner known per se.
  • the collector 18 is formed in one piece with two immobilizing lugs 36 formed in the sheet blank and attached to the collector 18 proper at its two longitudinal ends 32.
  • Each of the immobilizing tabs 36 has a generally rectangular shape and is attached to the corresponding end 32 by a tongue 38 of generally rectangular shape, which is limited by two sides 40 (FIG. 2) extending parallel to the axis XX .
  • the tab 36 ( Figure 1) is limited by a large side 42 attached to the tongue 38 and another large side 44, and by two small sides 46 located symmetrically on either side of the axis XX.
  • notches 48 located symmetrically on either side of the axis XX and in the extension of the sides 40 of the tongue 38 ( Figures 1, 2 and 4).
  • the tab 36 has a central core 52 located in the extension of the tongue 38 and two lateral wings 54 connected to the core 52.
  • the notches 48 make it easier to fold the tab 36 along a folding axis 56 perpendicular to the axis XX, which makes it possible to form an edge 58 slightly open attached to the core 52 and two edges 60 slightly open and attached respectively to the two wings 54, as shown in FIGS. 1 to 4.
  • At least one collector 18 formed by cutting a metal sheet.
  • the latter is then stamped so as to constitute a peripheral groove (not shown) suitable for subsequently receiving the peripheral rim 22 of the water box 24.
  • the two wings 54 are also folded at right angles to the core 52 , which makes it possible to provide a folded tab with a U-section as shown in FIGS. 1 and 2.
  • edge 58 and the two edges 60 have advantageously been folded along the axis 56 before the two wings 54 are folded.
  • the tongue 38 comprises a recess formed by two adjacent fold lines 62 which extend parallel to each other and perpendicular to the direction XX.
  • This recess allows the tongue 38 and the core 52 to bypass the longitudinal end 32 of the manifold 18 so as to come as close as possible to the fins 14.
  • each of the legs 36 it then suffices to fold each of the legs 36 around an axis 64 which extends perpendicular to the axis XX and which constitutes the connection between the end 32 of the collector and the corresponding tongue 38.
  • the immobilization tab 36 is then pivoted by approximately 90 °. Then, the manifold 18 is assembled in a conventional manner to the harness 10 and then to the water box 34.
  • each of the immobilizing lugs 36 extends parallel to the direction of the tubes 12 so as to bear against the edges of a certain number of fins 14 of the beam.
  • the folded tab 36 in the position thus represented, covers a longitudinal end of the bundle, the core 52 coming to bear against an end face of said bundle and the two wings 54 coming to bear against two longitudinal faces of the beam.
  • the bundle of tubes is perfectly immobilized with respect to any pivoting or torsional movements relative to the manifold-water box assembly.
