Definitions

  • the present invention relates to a heat exchanger, in particular a cooling radiator for a motor vehicle according to the preamble of claim 1.
  • a heat exchanger in particular a cooling radiator for a motor vehicle according to the preamble of claim 1.
  • Such an exchanger is known according to FR-A-2 042 437.
  • a heat exchanger comprises at least one fluid collecting box into which opens, sealingly, a bundle of tubes provided with fins arranged either perpendicular to the longitudinal direction of the tubes by being fixed to them by brazing or mechanical assembly. , or parallel to the same direction by being fixed thereto by soldering.
  • FR-A-2 042 037 it is mentioned to attach lateral or cheek portions to the lateral edges of the tube bundle and to fix these on said edges by means of an adhesive paste, preferably made of epoxy resin. which, after drying, provides a rigid connection between the lateral edge of the bundle and the cheek used to support and maintain accessory members linked to the exchanger, such as the cooling fan, and / or to fix the radiator to the vehicle .
  • This arrangement nevertheless has the drawback of rigidly linking the cheek with the beam and the vibrations produced, either by the vehicle in operation in the case where the radiator is fixed to the vehicle by the cheeks, or by the members linked to the exchanger. , are transmitted directly to the bundle of finned tubes and can damage the latter, and more particularly at the level of the attachments of the fins on the tubes or at the level of the sealed attachment of the tubes in the fluid collecting box.
  • the finned tube bundle undergoes large longitudinal expansions during operation and more particularly at the level of the tubes on which the fins are fixed, which are rigidly connected, in addition, to one of their ends on the cheek by the epoxy resin. .
  • the present invention aims to remedy these drawbacks and proposes, for this purpose, a connection between the cheek and the bundle of finned tubes of simple design while providing a reliable connection between them.
  • a heat exchanger in particular a cooling radiator for a motor vehicle, comprising at least one fluid collecting box into which leaks out a bundle of finned tubes, at least one lateral edge of which is provided with at least one cheek, is characterized in that the cheek is connected to the lateral edge of the bundle of finned tubes by a flexible sealant, in that the cheek is placed at a distance from the lateral edge of the bundle and in that the space left free is, at least in part, filled with putty.
  • this arrangement not only prevents the transmission of vibrations, but allows a certain movement of the end of the fin in the flexible mastic.
  • the heat exchanger 1 here a cooling radiator, comprises at least one fluid collecting box, here two, 2, 3, in each of which opens with sealing, one end of a bundle 4 of tubes 5 provided with fins 6.
  • These tubes 5 are provided, here, with corrugated fins 6 arranged parallel to the longitudinal direction of said tubes by being fixed thereto by brazing, for example, but it would not depart from the scope of the invention by having flat fins perpendicular to the longitudinal direction of the tubes 5 and by fixing them by mechanical assembly or by brazing.
  • the cheeks 8 are capable of carrying tabs 10, 11 projecting from the said cheeks and which can be used for fixing a member linked to the exchanger, such as a support used for the reception of '' an electric motor driving a fan and / or fixing the radiator to the vehicle.
  • the cheek 8 is fixed to the lateral edge 7 of the bundle of finned tubes by a flexible mastic 9.
  • This sealant is a two-component polysulfide sealant such as that sold under the name "Scotch Alone” which, after setting, gives a certain flexibility as well as an elasticity to said sealant.
  • said cheek is disposed at a distance D from the edge 7 and the space thus created is filled in. less in part by the flexible mastic 9, here entirely.
  • the flexible mastic 9 under form at least one bead or in the form of a ribbon and bring the cheek 8 towards the edge 7 so that, if the putty is in the form of a cord, crush the said cord so that the -this turns into a ribbon and, once this shape has been reached, bring the cheek 8 closer to the edge 7 so that the putty 9 penetrates beyond the edge 7.
  • the mastic is deposited in the form of a ribbon, it is sufficient to bring the cheek 8 together so as to obtain penetration of the mastic beyond the edge 7.
