Definitions

  • the tubes are fixed to the manifolds by brazing, which makes it possible to promote the sealing of the connection.
  • the fins are also brazed on the tubes.
  • the tubes, on the one hand, and / or the manifolds and the fins on the other hand, must be coated with a layer of plating allowing brazing.
  • This solution also requires the use of a flux which must be applied to the whole of the exchanger to promote the diffusion of the plating layer during brazing.
  • the object of the invention is to remedy these drawbacks
  • the invention thus relates, first of all, to a heat exchanger comprising a bundle of fluid circulation tubes, at least one collecting element, the two ends of each tube engaging in a fluid tight connection in holes. reception provided in the collecting element (s), and means for promoting the heat exchange between an air flow passing through the exchanger and the fluid circulating in the tubes, characterized in that the connection between the ends of the tubes and the collector (s) is constituted by a brazing joint and the means for promoting heat exchange are able to be assembled mechanically on the tubes after brazing the latter and the collector elements.
  • the fins are constituted by a corrugated plate having ripple ridges turned towards the tubes and which extend parallel to said alignment direction, each of said cutouts overlapping one of the ripple ridges.
  • Figures 1 is a perspective view illustrating an example of a heat exchanger according to the invention.
  • the tubes 2 extend beyond the tubes 23 and are therefore not in contact with the sheet 20 over the entire width of their planar lateral faces.
  • the tubes may be entirely between the plane of the folds 22 and that of the folds 23, thus increasing the exchange surface between the tubes and the fin block.
  • said exchanger constitutes a radiator for cooling a motor vehicle engine. It may however be any other type of exchanger, such as a condenser. Such use is illustrated in Figures 7 to 9, in the particular context of a module.
  • the invention also relates to a heat exchanger module comprising a fin block 30 common to a first exchanger, for example a radiator for cooling the drive motor of a vehicle, and to a second heat exchanger, for example a condenser belonging to a vehicle air conditioning loop.
  • the radiator 40 comprises, for example, a row of flat tubes 41 (FIG. 8) and two fluid boxes each formed by a collecting plate, crossed by the ends of the tubes, and by a hollow part 41 assembled in a fluid-tight manner at the periphery of the collector plate.
  • the condenser 50 comprises a row of tubes 51 and two tubular manifolds 52 having openings for the passage of the ends of the tubes.
