  • the invention also relates to a heat exchanger comprising at least one collector as mentioned above.
  • a heat exchanger 1 It comprises a bundle of tubes 100, intended to be traversed by a fluid exchanging heat with a flow of air through the exchanger, alternating with inserts 110, arranged between the tubes 100 to increase the exchange surface.
  • Said heat exchanger 1 also comprises a bipartite collector 2, with a lower part 3 and an upper part 4. That being so, the terms “lower” and “upper” do not presage the orientation of the collector or the orientation of the collector. exchanger in which said collector is used, the exchanger can be oriented so as to allow circulation vertical flow of fluid flowing through its tubes.
  • the lower part 3 forms the base of the collector 2 and comprises a bottom 5, longitudinal walls 6 terminated by longitudinal edges 7, for example rectilinear, and transverse walls 8.
  • the upper part 4 forms the cover of the collector 2.
  • the dimensions of the cover 4 are designed to allow insertion and reception of the cover 4 between the longitudinal walls 6, when the longitudinal edges 7 are in the upright position.
  • the exchanger 1 further comprises two fluid inlet / outlet flanges 9 each allowing the reception of a fluid line (not shown in the accompanying figures).
  • the exchanger 1 also comprises two other flanges forming two fastening lugs 10. These fastening lugs 10 make it possible to secure the exchanger 2 to a support (not shown in the appended figures), according to various fixing possibilities. known to those skilled in the art.
  • the inlet / outlet flange 9 has a particular profile 11. This profile 11 allows the reception, at the flanks 12 of the flange 9, the longitudinal edges 7, once the latter folded.
  • the profile 11 allows the insertion of the inlet / outlet flange 9 between the longitudinal edges 7 when they are in the upright position and the crimping of the flange 9 by folding said longitudinal edges 7 on the flanks 12.
  • the profile 11 has a groove 13 formed in a flank 12 of the flange 9 and on its other side 12 a protrusion 14.
  • the protrusion 14 has a lower face 15 substantially matching the shape of the lid 4 and a side face 16 abutting the inside of the longitudinal wall 6 of the lower part 3. In this way, when the longitudinal edges 7 are folded for one in the groove 13 and for the other on the protrusion 14, on the one hand the crimping of the flange 9 on the cover 4 is obtained and on the other hand the clasping of the cover 4 between the flange 9 and the lower part 3.
  • the crimping of the flange 9 therefore makes it possible to securely hold the cover 4 between the lower part 3 and the flange 9 in a single crimping operation.
  • the groove 13 and the protrusion 14 extend over the entire length of the flanks 12 of the flange 9.
  • the fixing lugs 10 are also designed to be secured to the lid 4 and the lower part 3 simultaneously with the crimping operation of the flanges 9.
  • the profile 17 of the fixing lugs 10 comprises, for example, two wedge-shaped ends 18.
  • Each corner 19 matches the surface of the cover 4 and fits into the space formed between the cover 4 and the longitudinal walls 6 of the lower part 3.
  • the fastening between the fixing lugs 10, the cover 4 and the lower part is obtained when the longitudinal edges 7 are folded over the corners 19 preventing any movement of spacing of the tabs 10 vis-à-vis the cover 4 and the lower part 3.
  • This inclination is obtained by varying the length of the protrusion 14 and the depth of the groove 13. It is thus possible to precisely obtain different inclinations of the flange 9 with respect to the collector 2. referring to the figure 3 a possible example of inclination between the flange 9 and the collector 2, the inclination being controlled by the dimensions of the groove 13 and the protrusion 14.
  • the orientation of the fixing lug 10 with respect to the collector 2 is controlled by varying the length of the corners 19.
  • the corners 19 are substantially identical, however, to obtain other inclinations, may be provided corners 19 of non-identical lengths.
  • the exchanger may also comprise a bottle 40, provided in fluid communication with the collector.
  • a bottle is oriented parallel to the collector 2 and has a wall 42, defining an inner volume 44.
  • Such a bottle serves, in particular, to define a fluid storage volume and / or to facilitate phase separation, when associated with a condenser.
  • Said bottle may also be equipped with a filter and / or a desiccant cartridge, not shown.
  • Said collector may then be provided with a flange, as mentioned above, this time defining a flange 30 for attaching the bottle 40, said attachment flange 30 possibly being provided in continuity of material of the bottle 40.
  • the fastening flange 30 is of the excrescence type 14 or corners 19.
  • the collector 2 may comprise partitions dividing its internal volume into several parts, each connected to a given number of tubes of the exchanger, defining fluid circulation passes, with to effect an alternating circulation of the fluid in an alternating direction from one pass to another.
  • the cover 4 can bear on the lower part 3 by means of said partitions and / or transverse walls 8 alternatively and / or complementary to a support made by the stops 20.
  • the proposed structure makes it possible simultaneously to crimp the various types of flanges 9, 10, 30 provided for the collector 2, while ensuring the maintenance of the cover 4.
  • the folded edges 7 will be present, for example, at the level of said flanges, at least at the level of at least one of said flanges, and it is the crimping of said flange (s) by the folded edges 7 which will block the lid 4 on the lower part 3. It can also be provided folded edges 7 beyond said flanges to ensure a locking position of the lid not only by the flanges but also by the folded parts, then in direct contact with said cover, provided beyond the flanges.
  • the method of assembling the exchanger consists in carrying out a first step of positioning the cover 4 of the collector 2. To do this, the cover 4 is inserted into the lower part 3 until it reaches the stop 20. different flanges input / output 9 are positioned on the cover 4. This positioning of the flange 9 is easy since it is sufficient to move vertically the flanges 9 to the contact with the cover 4 by matching the openings provided on the cover 4 with those provided on the flanges 9.
  • the heat exchanger 1 has fastening lugs 10 at the collector 2, the positioning of the fastening lugs 10 is consequently also carried out. However, this step is naturally omitted when the fastening lugs 10 are not removed. disposed on the cover of the collector 2 or in a degraded embodiment of the invention wherein the fastening lugs 10 are fixed in a conventional manner on the lid 4 in particular by welding or stapling.
  • the method of assembly of the exchanger 1 then consists in carrying out a step of folding the longitudinal edges 7.
  • This folding step makes it possible to position the end of the longitudinal edges 7 in the grooves 13 and on the protuberances 14 of the flanges 9 and as appropriate, on the corners 19.
  • the grooves 13 and the protuberances 14 of the flanges 9 extend only partially along the length of the components 9 and 10.
  • the longitudinal edges 7 may be in the form of crimping tabs distributed along the sidewalls, for example regularly and / or so as to coincide with the locations of the grooves, excrescences and / or corners flanges, the assembly being performed after folding said crimping tabs.
