Definitions

  • the box generally extends in a longitudinal direction (from preferably substantially vertical).
  • the entry of the fluid into the manifold takes place in an upper part, while the exit takes place in a lower part.
  • Entry and exit are generally connected to the installation, via tubing, to a common connector whose location may vary from vehicle to vehicle.
  • Such a connection often imposes complex shapes on tubing and little adaptability, which makes them bulky and expensive due, in particular, to folding operations.
  • One of the aims of the invention is therefore to provide an exchanger of heat which does not have all or some of the disadvantages prior art exchangers.
  • a first tube independent of the realization of the manifold, substantially parallel to it, connected to the first tubing, and comprising a first opening which extends longitudinally
  • the first box collector is provided with a second opening which extends also longitudinally.
  • It also includes a first connecting plate comprising, on the one hand, first and second edges with longitudinal extensions substantially equal to those of the first and second openings and intended to be respectively introduced into them so as to secure the first manifold to first tube, and secondly, a passage to allow the circulation of a fluid between the first manifold and the first tube.
  • the second opening extends over the entire length of the first box collector, and on the other hand, the first opening extends along the entire length of the first tube. This allows to simplify the production of the manifold and the tube, insofar as a simple folding without removing material (for openings) is enough to make them.
  • the exchanger comprises a second manifold which extends longitudinally (substantially parallel to the first manifold), said beam then being mounted between the first and second manifold boxes.
  • a second tube is also provided independent of the first manifold, substantially parallel to it and in the extension of the first tube, connected to the second tube, and provided with a third opening extending longitudinally to receive the first edge of the first connecting plate, which for this purpose has a longitudinal part of length substantially equal to that of the third opening, so as to secure the second tube to the first box collector.
  • a second passage in the first connection plate we provides for a second passage in the first connection plate.
  • a second independent tube is provided of the second manifold, substantially parallel to this one, connected to the second tubing, and provided with a third opening which extends longitudinally.
  • a second connecting plate which comprises, on the one hand, first and second edges having longitudinal extensions substantially equal to those of the third and fourth openings and intended to be respectively introduced into these so as to secure the second manifold to the second tube, and on the other hand, a second passage for allow the circulation of the fluid between the second box manifold and the second tube.
  • the first and second tubes can be made in the same folded metal plate comprising a transverse partition for prohibit any communication between them, which simplifies the realization of the exchanger (at least in terms of assembly).
  • the second manifold is made of preferably by folding a metal plate, a second hand, the third opening extends over the entire length of the second tube, and on the third hand, the fourth opening extends over the entire length of the second box collector.
  • a first connector block in which is formed by extruding the first tube, and which comprises a first axial housing communicating with the first tube and allowing the introduction of the first tube.
  • a second block in which is formed by extrusion the second tube, and comprising a second housing axial communicating with the second tubing and allowing the introduction of the second tube.
  • Such an embodiment provides the tubes with very good resistance to vibrations, since they are now joined together, even before soldering, to the manifold with which they communicate respectively, due including their cooperation with the first and second tubes.
  • first and second tubing when the entry and exit are provided on the same manifold, we can provide a single block in which are formed by extrusion the first and second tubing, and which includes first and second axial housings communicating respectively with the first and second tubing and allowing respectively the introduction of the first and second tubes.
  • the invention relates to heat exchangers, in particular for motor vehicle.
  • the heat exchanger is a condenser of a cold loop of a heating and air conditioning system of motor vehicle.
  • FIG. 1 there is shown in Figure 1, in cross section, a so-called multi-pass condenser comprising a bundle of parallel tubes 1 mounted between a first manifold 2 and a second manifold 3.
  • the manifolds 2 and 3 have an extension longitudinal in a direction which, in this example, is vertical (X-X axis).
  • Beam tubes 1 are installed in a direction substantially transverse to the X-X axis and are separated from each other by corrugated dividers 4 whose purpose is to promote heat exchanges between a refrigerant which circulates inside the tubes 1 beam and air flowing between these tubes.
  • the box collector 2 is subdivided into three sub-chambers 5 to 7, an upstream sub-chamber 5, a downstream sub-chamber 6 and a sub-cooling sub-chamber 7.
  • the second manifold 3 is subdivided into two sub-chambers 8 and 9, an upstream sub-chamber 8 and a sub-chamber downstream 9.
  • each manifold is separated from each other by partitions 10. Furthermore, the ends of the manifolds 2 and 3 are obstructed by end partitions 11.
  • the refrigerant in the upstream sub-chamber 5 of the first manifold 2, circulates in the tubes 1 of the bundle which open into this sub-chamber 5, reaches the upstream sub-chamber 8 of the second manifold 3 from which it emerges by ends of new tubes 1 with opposite ends open into the downstream sub-chamber 6 of the first box collector 2. Having reached this downstream sub-chamber 6, the fluid comes out of tube ends 1, then reaches by opposite ends of these tubes in the sub-chamber downstream 9 of the second manifold 3.
  • first manifold 2 To allow the introduction into the first manifold 2 of the refrigerant to be cooled and condensed, provides an inlet manifold 12 which communicates with a first feed tube 13 installed in one position substantially parallel to the first manifold 2, and communicating with it through a first pass 14 forming a slot (see FIGS. 3A and 3B), produced in a connecting plate 18 to which we will return later.
  • This first slot 14 has a longitudinal extension adapted to the shape, and therefore to the performance, of the upstream crazy chamber 5 of the first manifold 2.
  • the first supply tube 13 and the second discharge tube 16 are secured to the first manifold 2 via the connecting partition 18, which has a first longitudinal edge 19 and a second edge longitudinal 20 intended to be introduced respectively in openings 24, 23, 27, made in the walls delimiting the first 13 and second 16 tubes, as well as the first manifold 2.
  • the opening 23 made in the first manifold 2 does not have a longitudinal extension equal to the length (or height) of this manifold 2, it would not be necessary for the second edge 20 of the connecting partition 18 extends over all the height of the manifold, but simply on the height corresponding to the longitudinal extension of the opening 23.
  • the supply 13 and discharge 16 tubes are produced in much the same way as the first manifold 2, from metal plates folded so as to delimit a cylinder, of substantially parallel generatrices to the X-X axis, and of longitudinal extension chosen.
  • the first 13 and second 16 tubes are produced in two separate elements, but it is clear that one could consider carrying them out at from a single metal plate provided in one place chosen from a partition to allow separation to seal these two tubes.
  • the first feed tube 13 includes an opening longitudinal 24 delimited by the longitudinal edges 25 and 26 of the wall which constitutes it, which edges are separated for this purpose.
  • the opening 24 extends over the entire height (or length) of the first feed tube 13.
  • the first longitudinal edge 19 of the bulkhead link 18 can thus be introduced inside the opening 24.
  • This first supply tube 13 is positioned so that the first slot 14 made in the connecting plate 18 is partially housed inside of space delimited by its wall. In this way, the fluid, which arrives through the inlet tube 12, arrives in the tube supply 13, passes through the first slot 14 of the plate link 18, and opens into the upstream sub-chamber 5 of the first manifold 2.
  • the inlet tubing 12 and the tubing of outlet 15 are produced by extrusion, in a metal block connection 28 intended to be connected directly to a additional connector for the installation's cold loop.
  • the connector block 28 comprises a first longitudinal recess 29 which communicates with the inlet pipe 12 and intended to receive the open end of the first tube supply 13, so as to allow the circulation of the fluid from the inlet tubing 12 to said supply tube 13.
  • This connector block 28 includes a second recess axial 30 which communicates with the outlet pipe 15 and intended to receive the open end of the second tube evacuation 16, so as to allow the circulation of the fluid from this discharge tube 16 to the outlet pipe 15.
  • first connector block could be provided for the first supply tube 13, and a second connector block, completely independent of the first connector block, for the second discharge tube 16.
  • second connector block completely independent of the first connector block, for the second discharge tube 16.
  • single connector block 28 provided with a axial recess over its entire length so as to allow the introduction of a wall defining at the same time the first supply tube 13 and the second discharge tube 16.
  • the connector block or the connector blocks can be positioned anywhere included at least between the two ends of the first manifold 2. It is enough to do this on the respective lengths of tubes 13 and 16.
  • the connector block (s) which now integrate the inlet and outlet pipes have a resistance in high vibration insofar as they are joined to the first manifold 2 via the plate connecting 18 and supply 13 and evacuation tubes 16.
  • the connecting plate 18 is a plate metallic in the thickness of which are made the first 14 and second 17 slots, as illustrated on the Figures 3A and 3B.
  • the materials constituting such an exchanger and in particular the first and second tubes, the manifolds, the bundle tubes and connector blocks are made of aluminum.
  • These different constituents are definitively united with one another by a passage through an oven, for example brazing, or welding.
  • the first connection plate 34 has only one first passage 40 forming first slot. This first plate is made in the same way as the connecting plate referenced 18 in the previous embodiment (see Figures 3A and 3B).
  • the first connecting plate 34 does not extend only over part of the height (or length) of the first manifold 2. Consequently, the opening 39 of the first manifold 2 extends only over part of the total height thereof, and more precisely on a height equal to the longitudinal extension of the second edge 36 of the first partition 34.
  • This opening 39 is for example produced by local cutting of the longitudinal edges of the wall which delimits the first manifold 2.
  • first metallic connector block 41 in which is made by extrusion the inlet pipe 12, and which includes an axial recess 42 communicating with the tubing input 12 and allowing the introduction of the end open the first feed tube 38.
  • the second manifold 3 is almost identical to the first manifold 2 which has just been described. His embodiment is therefore identical to that which has just been described.
  • This second manifold 3 therefore includes a longitudinal opening 43 which extends only over a part of its height and intended to receive a second edge longitudinal 44 of a second connecting plate 45.
  • This second connection plate 45 includes a second passage 46 forming a second slot 47 allowing communication between the downstream sub-chamber 9 of the second manifold 3 and a second discharge tube 47 which communicates with the outlet pipe 15.
  • the second discharge tube 47 is produced in the same way that the first feed tube 38, namely from of a metal plate folded into the shape of a cylinder generators substantially parallel to the X-X axis. He understands also a longitudinal opening 48 intended to receive the first edge 49 of the second connecting plate 45. In this example, the longitudinal extension of the opening 48 is equal to the height (or length) of the wall which delimits the second discharge tube 47.
  • the outlet tubing 15 is, like the inlet tubing
  • a second connector block 50 which further comprises an axial recess 51, which communicates with the outlet pipe 15 and allowing the introduction of the open end of the second discharge tube 47.
  • first 34 and second 45 connecting plates longitudinal extension substantially equal to that of manifolds 2 and 3.
  • the opening made in each of the manifolds should extend over the entire height of the boxes.
