Definitions

  • the invention relates to a rigid assembly comprising a first heat exchanger of generally flat shape, comprising at least one upper fluid box made of plastic material, and an expansion vessel in fluid exchange relationship with the upper fluid box, located near it; cf. for example EP-A-0 219 419 and FR-A-2 272 858.
  • the expansion tank can be formed in one piece with the upper fluid box, or fixed directly to the latter.
  • this solution would require a considerable reinforcement of the fluid box so that it can resist the forces exerted by the expansion tank. due to its own weight and the vehicle's acceleration.
  • first heat exchanger used for cooling the engine a second generally flat heat exchanger used for cooling the charge air of the engine, or more precisely the air leaving the turbocharger used for the charge air, the first and second heat exchangers being oriented parallel to the same substantially vertical plane and juxtaposed so as to be traversed in series by an air current directed perpendicular to this plane.
  • the fluid boxes of the second heat exchanger are generally made of metal, in particular of aluminum alloy.
  • the object of the invention is to take advantage of these metal elements of the second heat exchanger to secure the expansion tank.
  • the invention relates in particular to an assembly of the kind defined in the introduction, and provides that it comprises a second heat exchanger of generally flat shape, the first and second heat exchangers being oriented parallel to the same substantially vertical plane and juxtaposed so as to be crossed in series by an air flow directed perpendicular to this plane, and the expansion tank is rigidly fixed to at least one element of the second heat exchanger.
  • the illustrated assembly includes a radiator 1 for cooling the thermal engine driving a motor vehicle and a radiator 2 for cooling the charge air of this engine.
  • the radiator 1 has a generally flat rectangular shape and extends substantially along a vertical plane perpendicular to the longitudinal axis of the vehicle. It includes two fluid boxes in material plastic 3 and 4 extending horizontally, along the upper and lower sides respectively of the radiator and provided with fittings 5 and 6, one of which is used for the inlet and the other for the outlet of the coolant.
  • the fluid boxes 3 and 4 are connected to each other by vertical fluid circulation tubes.
  • the radiator 2 also has a generally flat shape and extends along a plane parallel to that of the radiator 1, being substantially attached to the face of the latter facing the front of the vehicle.
  • the radiator 2 comprises two fluid boxes 7 and 8 molded of aluminum alloy, elongated in the vertical direction and extending respectively along the left and right sides of the radiator 1.
  • the fluid boxes 7 and 8 are interconnected by the horizontal tubes for the circulation of the air to be cooled.
  • the upper region 9, 10 of each of them forms an air inlet or outlet pipe which is bent backwards and bypasses the radiator 1 at the ends of its upper fluid box 3, to be connected to the charge air compressor and the intake manifold, not shown, located behind the set of radiators.
  • the fluid box 3 is in fluid communication connection with an expansion tank 11 of cylindrical shape of revolution whose axis is parallel to the longitudinal direction of this same fluid box.
  • the expansion vessel 11 is made of brass. Its length is less than the width of the space available between the pipes 9 and 10, in front of the radiator 1. It is therefore arranged partly in this free space, and partly in front with respect to the front face of the radiator 2 It also extends, in the vertical direction, partly opposite the upper fluid box 3 of the radiator 1, partly above and partly below the latter.
  • the expansion vessel 11 is fixed on two pairs of legs which have been molded with the tubes 9 and 10 respectively and arranged symmetrically with respect to the median vertical plane of the vehicle. Each pair includes a lower tab 12 and an upper tab 13.
  • the lower tab 12 extends horizontally forward and towards the median plane from the tubing 9 or 10.
  • the expansion vessel rests on its upper face by means of a junction piece 14 which is welded to the external face of the cylindrical wall of the vessel. expansion and protrudes beyond the end thereof, where it is connected to the lug 12 by a bolt 15 near the vertical axial plane 16 of the expansion vessel.
  • the upper tab 13 extends from the upper horizontal region of the tube 9 or 10 in the direction of the median longitudinal plane of the vehicle, in a plane slightly inclined relative to the vertical.
  • To this upper tab is also connected by a bolt 17 a junction piece 18 welded to the outer face of the cylindrical wall of the expansion vessel, the piece 18 moving away enough from this wall to allow the housing of the bolt. This is contained in the right dihedral delimited by the half-planes extending rearward and upward respectively from the longitudinal axis of the expansion vessel.
  • the expansion vessel may be rigidly fixed at one of the fluid boxes and to slide freely, in the direction of the tube bundle, at the other 7 of the fluid boxes so as to allow unhindered expansion of the tube bundle.
  • this can be done by providing a bolt 17, at the level of the fluid box 7, which is shouldered and this at the level of the connection of the tab 13 and of the junction piece 18.
