Definitions

  • the invention relates to heat exchangers, in particular air conditioning condensers for motor vehicles, comprising a fluid box with a tubular wall having openings elongated transversely to its axis and mutually aligned along it to receive a row of tubes of fluid circulation.
  • the assembly of the circulation tubes and of the tubular wall is usually carried out by moving the latter, relative to the set of aligned tubes, in the longitudinal direction thereof so as to penetrate the ends of the tubes into the openings of the tubular wall. If, in an automatic assembly device, the tubular wall is very slightly offset laterally with respect to the row of tubes, or if these are not perfectly aligned, the ends of the tubes or of some of them will not come not strictly in coincidence with the openings, which will cause deterioration of the parts concerned or a blocking of the assembly operation.
  • the object of the invention is to remedy this drawback.
  • the invention relates to a tubular wall for a heat exchanger fluid box, having openings elongated transversely to its axis and mutually aligned along it to receive fluid circulation tubes of elongated cross section. , characterized in that it is formed from two parts assembled in a fluid-tight manner and each extending over a part of the circumference of the tubular wall, and in that tabs cut out from the wall to form said openings are folded substantially along the longitudinal axis of the tubes and respectively at the two ends of each opening.
  • the legs can be oriented outward or inward.
  • the openings and the tabs are made in one of the two parts.
  • the two tabs then deviate slightly from each other towards the outside of the wall to ensure centering of the corresponding tube at the time of assembly.
  • the openings are each formed by two notches made respectively in the two parts, the two tabs associated with the same opening belonging respectively to the two parts.
  • the two legs can then be substantially parallel to each other.
  • the assembly can be carried out by a movement of each component part of the tubular wall perpendicular to the longitudinal direction of the tubes.
  • the invention also relates to a method for manufacturing a heat exchanger comprising a tubular wall as defined above and a row of fluid circulation tubes of elongate cross section engaging the openings, method in which each of the two constituent parts of the tubular wall is moved relative to the row of tubes in the longitudinal direction of the cross section thereof, the two parts being moved towards each other on either side of the ends of the tubes, which penetrate into the notches of the parts, until the tabs abut on the tubes, and the two parts are assembled in a leaktight manner.
  • At least one disc intended to form a transverse partition of the fluid box is placed on one of the two parts, the peripheral edge of this disc coming into contact with the concave internal surface of the second part at the end of the relative movement of the two parts and then being tightly linked thereto.
  • Figure 1 shows by way of example a fluid box 1 comprising a tubular wall 2 having six openings 3-1 to 3-6 for receiving as many fluid circulation tubes of which only four are partially represented under the references 4-2 , 4-3, 4-5 and 4-6 to allow a better view of the tubular wall.
  • a spacer 5 consisting of a strip of metal sheet folded in a zigzag or curved in the form of a sinusoid is placed between the tubes 4-5 and 4-6 and in thermal contact with them. Such spacers are associated with each pair of consecutive tubes of the condenser.
  • the tubular wall 2 is formed of two substantially semi-cylindrical parts 6 and 7, the part 7 being partially torn off to allow a better view of the part 6.
  • the longitudinal marginal zones 8 and 9 (FIG. 2) of the part 7 externally cover the longitudinal longitudinal zones 10 and 11 respectively of the part 6 to which they are assembled in a sealed manner to the fluid intended to circulate in the condenser, for example by brazing.
  • Each of the openings 3 is formed by a notch formed in the part 6 from the zone 10 and by a notch formed in the part 7 from the zone 8.
  • the two sides of each notch are connected to the corresponding edge of the part. by a chamfer 12.
  • a tab 13 is left attached to the remaining part of part 6 or 7, at the bottom of each notch, and extending outward of the fluid box parallel to the longitudinal direction of the tubes.
  • the two tabs 13 associated with the same opening 3 come to bear respectively on the two small longitudinal sides 14 of the corresponding tube 4, that is to say at the ends of the elongated cross section of the tube.
  • FIG. 1 also shows a partition 15 intended to limit the fluid box 1 at one longitudinal end thereof, another similar partition not visible being provided at the opposite end.
  • the partition 15 is formed by a disc of which a part 16 of the peripheral edge is in sealed contact with the internal surface of the part 6 and another part 17 of the peripheral edge is in sealed contact with the internal surface of the part 7, one or several marginal regions of the disc, limited in the circumferential direction, being housed in openings or notches 18 passing through the thickness of the piece 6, so as to allow positioning of the disc relative to the piece 6 during assembly.
  • the region 17 of the peripheral edge of the disc 15 approaches the inner surface of the part 7 and comes into contact with the latter at the end of the stroke. Sealing at this level can then be achieved for example by brazing, the sealed connection between the disc 15 and the part 6 can be performed at the same time, during the brazing operation of all the parts.
  • the longitudinal marginal zones 8, 10, 9, 11, overlapping two by two, parts 6 and 7 constituting the tubular wall of the fluid box are located substantially in the median longitudinal plane P of the fluid box 1 and the row of tubes 4.
  • these marginal zones are located on either side of the median longitudinal plane, the openings for passage of the tubes and the legs being formed in only one of these rooms.
  • the assembly between this part and the tubes is then done in the usual way by a relative movement in the longitudinal direction of the tubes.
  • the legs ensure centering of the tubes in the longitudinal direction of their cross section. For this purpose, preferably, they deviate slightly from each other in this direction, at least in their end region.
