Definitions

  • the invention relates to a fluid box for a heat exchanger.
  • heat especially a condenser in an air conditioning unit of the passenger compartment of a vehicle, comprising a wall tubular extending in a longitudinal direction and at minus two end walls delimiting inside the tubular wall a space to receive a circulating fluid, the tubular wall comprising two profiled elements formed from strips of curved sheet metal substantially in shape of gutter whose concavities are turned one towards the other, the two marginal regions of one of said elements being in fluid tight contact respectively with the two marginal regions of the other element over any the length of said space and one of the elements having openings aligned in the longitudinal direction for the passage of circulation tubes communicating with said space.
  • EP-A-375 896 describes a fluid box in which the marginal regions of one of the profiled elements are mutually parallel and fit into folds formed by the marginal regions of the other element, or come to cover, flat, these last marginal regions. To achieve mutual immobilization of the two elements before brazing, their marginal regions are "riveted” by local deformations, protrusions thus formed by one elements engaging if necessary in openings provided in the other.
  • the object of the invention is to simplify the mounting of the manifold, eliminating the described riveting step in this document.
  • the invention relates in particular to a fluid box of the defined kind in the introduction, and provides that over the entire length and at least a first zone of the height of said regions marginal, the outer faces of the marginal regions of a first of the profiled elements flares towards free edges of it and cooperate with the faces interior of the marginal regions of the second profiled element which are tightening towards the free edges of this one, so as to keep the two elements hooked to one another.
  • the term “height” refers to the direction in which the two gutters face each other, or to the longitudinal direction of the circulation tubes, which that is the orientation of the fluid box in space.
  • the invention also relates to a heat exchanger comprising at least one fluid box as defined above and a row of circulation tubes each of which engages in one of said openings, as well as a process to assemble such a heat exchanger.
  • the two are arranged profiled elements of the fluid box externally one to the other with their concavities facing each other, we move towards each other, their marginal regions get pushing back elastically to make a click, then the row of tubes is engaged in said openings and braze the whole.
  • the tubular wall 1 represented in FIGS. 1 and 1a is composed of two profiled elements 2 and 3 each formed at from a strip of substantially curved sheet metal shaped like a gutter. These two elements are mutually assembled by their respective marginal regions, the concavity of each of them being turned towards the other.
  • the profiles of elements 1 and 2, and the closed profile of the wall tubular 3 that they form, are symmetrical with respect to a S axis, oriented vertically in the figures.
  • On a zone 6 the height of the marginal regions of elements 2 and 3, limited by the free edges 7 of the element 2 and by the free edges 8 of element 3, the outer faces 9 of marginal regions 4 of element 1 flare out in direction of the free edges 7, while the inner faces 10 of the marginal regions 5 of element 3 go together tightening towards the edges 8.
  • the sides 9 of element 2, the concavity of which faces towards bottom, and the faces 10 of the element 3, whose concavity is facing upwards, are all tilted towards the S axis, from bottom to top.
  • the faces 10 being supported on the faces 9, this results in a mutual attachment of the two elements that holds them together.
  • Elements 2 and 3 are curved by stamping and have a substantially constant wall thickness.
  • the internal width of element 2 decreases while rising from the free edges 7 up to a relative minimum defined by moldings 12 made during stamping, then increases to a relative maximum to gradually decrease to the bottom 13 of the gutter formed by the element 2.
  • the fluid box has intermediate partitions 14 in the form of blanks whose contour conforms to the internal profile of the tubular wall 1. These partitions therefore have depressions 15 to receive the moldings 12.
  • the installation of partitions in element 2 can be carried out by snap-fitting with elastic region spacing marginal of element 2, the partitions being pushed in direction from the bottom of it.
  • elements 2 and 3 can also be snapped together, with elastic spacing of the marginal regions of element 3, the bottoms of the two elements being pushed towards each other.
  • the movement towards ruzement is limited by the arrival in abutment of the internal face of the element 3 on the peripheral edge partitions 14. Reverse movement is avoided by cooperation of the marginal regions of the two elements as described above.
  • the profiled element 3 has openings for the passage of non-fluid circulation tubes represented.
  • the tubular wall 20 of Figures 2 and 2a is also composed of two profiled elements, the lower element 3 being identical to that described above, while the upper element 21 differs from element 2. From the free edges 22 of element 21, its internal width remains constant up to a certain height, then decreases so continues to cancel at the bottom 23 of the element. To realize, in zone 6 of contact between the two elements, a inclined outer face 24 of each marginal region 25 of the element 21 cooperating with the inclined inner face 10 of the corresponding marginal region 5 of element 10, the outer faces 24 are struck, before stamping, with so as to gradually reduce the thickness of these regions marginal from the free edges 26 of the element. The absence of a minimum in the internal width of the element 21 not allowing the transverse partitions to click into place, these are held in place by crimping this element. The sequence of assembly operations is the same as previously.
  • the tubular wall 30 shown in Figure 3 includes a upper element 2 substantially identical to that described in relationship with Figures 1 and la, and a lower element 31.
  • the latter differs from element 3 described above in that that in an area 32 of the height located immediately above of zone 6, the interior faces 33 of its regions marginal 34 widening to the free edges 35 of this element for cooperating with the outer faces 9 of marginal regions 4 of element 2 which are tightening. This cooperation of the faces in the area 32 limits the bringing the two elements together, even in the absence of a partition transverse.
  • a circulation tube 36 engaged in an opening of the element 31, the end of which abuts against the free edges 7 of the element 2.
  • a manifold 37 inlet or outlet of the fluid passing through an opening in element 2.
  • the upper 41 and lower 42 profile elements have profiles similar to those of elements 2 and 31 in FIG. 3.
  • the essential difference is that the marginal regions of the upper element externally cover those of the lower element and no longer the reverse. In others terms, these are the inner faces of the top element 41 which cooperate with the external faces of the regions marginal 42.
  • the any transverse partitions must be mounted on the lower element before the mutual assembly of the two elements. The assembly operations are unchanged by elsewhere.
