Definitions

  • the invention relates to heat exchangers of the type comprising at least one fluid box having an elongated tubular wall, and a multiplicity of parallel tubes entering the fluid box through openings in the tubular wall.
  • the object of the invention is to remedy this drawback.
  • the invention relates to a heat exchanger fluid box comprising a tubular wall traversed by a multiplicity of openings aligned in the axial direction to receive fluid circulation tubes, characterized in that said tubular wall, in each of the portions of its length delimited by said openings, is entirely located on one side of a contact plane extending parallel to its axial direction, opposite said openings, and which comes into contact with it at at least two spaced contact points in the circumferential direction.
  • At least two different contact planes can be provided for different portions of the length of the tubular wall, for example for that or those housing a transverse wall whose periphery is in contact with the internal surface of the tubular wall on the one hand, and for those which do not comprise such a partition on the other hand.
  • the tubular wall can be applied stably, without the risk of pivoting, on one or more flat bearing surfaces on which the tubular wall is supported by all of its contact points, or on discrete support elements arranged in one or more planes on which the tubular wall is supported by its different contact points respectively.
  • Such a surface or such support elements can be used, either to give the tubular wall a prior orientation, which will be maintained by clamping means during assembly with the tubes, or during this assembly itself.
  • the support elements may if necessary belong to the bundle formed by the tubes and by fins extending between them.
  • the openings are elongated in the circumferential direction, and are symmetrical with respect to an axial plane of the tubular wall.
  • the contact plane will then be chosen perpendicular to this axial plane of symmetry.
  • the tubular wall is in contact with the contact plane along at least one straight line perpendicular to its axial direction.
  • it may include a flat surface portion located in the contact plane.
  • the tubular wall has, between its two contact points, or between two contact zones spaced in the circumferential direction and each extending over a certain axial length, a concavity facing the contact plane.
  • a concavity has the advantage of improving the resistance to pressure of the tubular wall compared to the configuration comprising a transverse contact line segment or a portion of planar contact surface.
  • the illustrated fluid box intended in particular to be part of a condenser of an air conditioning installation of the passenger compartment of a motor vehicle, comprises a tubular wall 1 which can in particular be formed from a rectangular metal sheet rolled into a cylinder shape and welded on itself edge to edge in a leaktight manner according to a generator 2.
  • a generator 2 In the wall 1 are formed openings 3 elongated in the circumferential direction and mutually aligned in the direction of its axis 4, intended to receive the ends of the condenser fluid circulation tubes.
  • the fluid box also comprises transverse partitions 5a, 5b, constituted by discs extending transversely inside the tubular wall 1, immobilized by crimping and brazed in a sealed manner by their periphery to the internal surface of the wall 1
  • Figure 1 shows such a partition 5a disposed in the vicinity of an axial end 6 of the wall 1 and constituting an end wall of the fluid box.
  • FIG. 2 shows an intermediate partition 5b separating two compartments 7 and 8 of the fluid box into each of which opens a part of the openings 3.
  • the openings 3 are located at the bottom of respective depressions 9 of the tubular wall.
  • the outer surface of the tubular wall 1 present in the region between two consecutive openings 3, in line with the partition 5b and in correspondence with a flat part of the edge thereof , a surface portion 10 included in a plane P parallel to the axis 4 and perpendicular to the longitudinal plane of symmetry of the wall 1.
  • this outer surface is flattened over a certain length both in the axial direction only in the circumferential direction of the tubular wall.
  • Figures 2 and 4 show that the tubular wall, midway between two consecutive openings in a region free of transverse partition, is convex outward in the longitudinal direction, but has a concavity 11 in the circumferential direction. It therefore comes into contact with the plane P exclusively by two points A and B spaced in the circumferential direction.
  • the deformation of the tubular wall inwards to make the contact points is limited by the presence of the transverse partitions such as 5a and 5b, and is less significant in the length portions comprising such partitions than in the other portions.
  • the tubular wall may be convex in the longitudinal direction and flattened in the circumferential direction, and come into contact with the plane P exclusively along a straight line extending in the circumferential direction, or flattened in the longitudinal and concave direction in the circumferential direction, thus coming into contact with the plane P exclusively along two lines extending in the longitudinal direction and spaced apart in the circumferential direction. All these configurations can be found both at the level of a transverse partition and in a region free of transverse partition.
  • the openings 3 can be produced in particular by sawing or by punching.
  • the dishes and hollows according to the invention can be obtained by localized deformations of the tubular wall, preferably before making the openings 3 so as not to modify the shape of these.
  • the transverse partitions 5a, 5b may have at their periphery, before assembly, circumferential dishes or recesses corresponding to those of the tubular wall.
  • the partitions can be circular, the deformation of the outer surface of the tubular wall being accompanied by a corresponding deformation of the partitions and / or a variation in the thickness of the tubular wall.
