Definitions

  • the invention relates to a heat exchanger with connected water boxes for motor vehicles, in particular for heavy goods vehicles.
  • Heat exchangers of this type comprise a bundle of tubes mounted between two water boxes, each of which is delimited by a wall of molded plastic material having two opposite lateral faces on which two uprights of shaped cross section are fixed. of U connecting the two water boxes and framing the bundle, each of the uprights comprising a core on which two lateral cheeks depend.
  • the two uprights which connect the water boxes then give such a heat exchanger high mechanical strength, which makes it possible to produce it in large dimensions and to mount it on a motor vehicle, in particular a heavy vehicle, where it must be subjected. in operation at high mechanical stresses due in particular to the vibrations of the motor and to the differences in expansion undergone by the tubes of the bundle.
  • the object of the invention is in particular to remedy the aforementioned drawbacks.
  • each upright comprises, in a manner known per se, an end provided with circular openings for rigid attachment to one of the two water boxes and a end provided with oblong openings for sliding attachment to the other water box, so as to compensate for variations in expansion.
  • tapping screws of the same type can be used both for rigid fixing of an upright on a water box and for sliding fixing of the upright on the other water box.
  • the ring can be an integral part of the self-tapping screw or else be threaded around the latter.
  • each of the lateral cheeks of an upright comprises an end connected by a recess, which allows this end to lie flat against the corresponding face of the water box.
  • each of the lateral cheeks has one end in its extension so that this end is supported on a face offset from the face of the water box.
  • each of the blind bores is formed in a boss formed in the wall of the water box.
  • the heat exchanger shown in FIGS. 1 and 2 comprises a bundle 10 which is formed from a multiplicity of tubes 12 passing through fins 14 and which is mounted between two water boxes 16 and 18.
  • the water box 16 placed in the upper part of the heat exchanger comprises a collecting plate 20 also called “plate with holes", into which the ends of the tubes 12 of the bundle open.
  • a collecting plate 20 also called “plate with holes”, into which the ends of the tubes 12 of the bundle open.
  • a wall 22 of molded plastic which delimits the water box 16. This wall comprises an inlet pipe 24 and a degassing pipe 26.
  • the water box 18, placed in the lower part, comprises a manifold plate 28 into which the other ends of the tubes 12 open as well as a molded plastic wall, in which an outlet pipe 32 and a drain pipe 34 are formed. .
  • the two water boxes 16 and 18 are connected to each other by two uprights 36, of U-shaped cross section, comprising a core 38 on which two lateral cheeks 40 depend.
  • Each of the two cheeks 40 comprises one end 42, of generally triangular shape , intended to be fixed on the water box 16 and an opposite end 44, of generally triangular shape, intended to be fixed on the water box 18.
  • Each of the ends 42 or 44 is fixed on the corresponding water box by the at least one self-tapping screw 46.
  • each of the uprights is fixed to one of the two water boxes by means of four self-tapping screws 46, which represents a total of 16 self-tapping screws for the heat exchanger.
  • the two uprights 36 thus frame the bundle 10.
  • the uprights 36 are also connected together, substantially at mid-height, by at least one tie rod 48, here two tie rods, extending transversely to the direction of the tubes 12 of the bundle.
  • each of the cheeks 40 of an upright 36 comprises a step 50 connecting it to its end 42 and another step 52 connecting it to its end 44.
  • the two ends 42 and 44 can thus be applied to flat against the water boxes 16 and 18 respectively, bypassing the protuberances formed by the collecting plates 20 and 28.
  • the wall 22 of the water box 16 comprises two opposite faces 54, substantially parallel to each other, on which are fixed respectively the two ends 42 of a post 36 and, correspondingly, the wall 30 of the water box 18 comprises two opposite faces 56 parallel to each other, on which are fixed respectively the two ends 44 of the same amount.
  • Each of the ends 42 (FIGS. 3, 5 and 6) is provided with two openings 58 of generally oblong shape, while each of the ends 44 is provided with two openings 60 of circular shape, to allow rigid fixing of each upright 36 on the water box 18 and a sliding fixing of each upright 36 on the water box 16.
  • each of the oblong openings 58 has a width l greater than the diameter d of circular openings 60 and a length L greater than the width l and extending in the direction of the length of the upright, to allow a clearance mutual of the two water boxes under the effect of the differences in expansion presented by the tubes 12 of the bundle as a function of the temperature of the fluid passing through them.
  • each of the opposite faces 54 of the water box 16 and in each of the opposite faces 56 of the water box 18 are formed bores 62 with smooth walls, which in the example are blind, and whose axis of each d 'them extends perpendicular to the plane of the corresponding flat face 54 or 56.
  • the bores 62 have come from molding with the corresponding water box and are formed in bosses 64 formed in the wall 22 of the water box 16 or in the wall 30 of the water box 18.
  • the self-tapping screw 46 shown in FIG. 7 successively comprises a threaded rod 66, a ring 68 in the form of a collar having an outside diameter D and a height h, a washer 70 of diameter greater than D and finally a hexagonal head 72.
  • the diameter D of the ring 68 is greater than the diameter d of an opening 60 and less than the width l of an opening 58. Its height h is greater than the thickness e of the end 42 or 44 of a cheek 40.
  • the ring 68 of a screw 46 presses against the end 44 around an opening 60 and thus ensures the tightening of this end 44 on a face 56 of the water box 18.
  • the ring 68 instead of being an integral part of the self-tapping screw 46, is simply threaded on the latter.
  • the bores 62 can be obtained by molding with the two water boxes and that the self-tapping screws 46 are introduced by simple screwing in force in the bores 62, the mounting and fixing of the uprights 36 are much simpler to realize that in the case of heat exchangers of the prior art.
  • each of the cheeks 40 does not include an offset 50.
  • the end 42 is located in the extension of the cheek 40, while that the faces of the bores 62 facing the end are located beyond the face of the wall 54 or 56 of the water box.
