Definitions

  • the present invention relates to a collector flange for a heat exchanger for the equipment of a motor vehicle.
  • It has more particularly as object, but not exclusively, a flange and a collector, having at least a collection chamber, for an exchanger in which circulates a heat transfer fluid cooled by an external air flow.
  • the heat exchangers intended for the circulation of the "R-744" must be adapted to satisfy the high operating pressure of this fluid. This is why these types of heat exchangers often have collectors with two arches or two chambers to allow a good resistance to pressure.
  • This system has several disadvantages. First, it makes particularly difficult the orientation of the tubing in the different directions required by the general structure under hood. Moreover, the distribution of the fluid between the two ducts does not take place in a balanced ratio, in particular this distribution is a function of the CO 2 pressure / flow rate.
  • the document is also known EP 1462749 in which the fluid supply is carried out using a tubular pierced at its end, this tubing being pierced either in its longitudinal direction or in its transverse direction.
  • the optimization of the distribution of the fluid in the two arches is effected by varying the outlet diameters or by offsetting the position of the tubing relative to the longitudinal center of symmetry of the box.
  • this embodiment lies in a high pressure loss due in particular to the fact that in both cases, the fluid hits a flat surface before distributing in the two chambers. Furthermore, this embodiment has a low mechanical strength, especially to torsion, since the collector / flange contact is made on two cylinders, without return.
  • the present invention intends to overcome the disadvantages of existing heat exchanger flanges.
  • the invention relates to a flange for feeding a collector, comprising at least two chambers, to a heat exchanger, the flange having an inlet for communication with a pipe carrying a coolant towards the collector, characterized in that it comprises at least two fluid circulation channels, respectively to each of the two chambers, extending linearly from the aforesaid inlet orifice, to form between them an angle less than 180 °.
  • ifice means that the flange according to the invention does not include any inlet chamber receiving the fluid from the tubing. Indeed, the inlet orifice of the flange according to the invention is solely constituted by the meeting of the two linear flow channels, without other cut or truncated portion of the flange.
  • the present invention is particularly well suited to heat exchangers in which circulates a gas at very high pressure, such as CO 2 .
  • the collector chambers are often small because of their thick walls necessary for the holding of significant pressures (of the order of 100 to 150 bars).
  • the tubing it is not possible for the tubing to directly feed the two or more chambers of the collector; the diameter of the tubing being classically lower than the thickness of the wall separating the two chambers of the manifold. This is especially visible on the figure 1 .
  • the present invention also relates to a collector for a heat exchanger, comprising at least two chambers for the circulation of at least one fluid, characterized in that a flange, according to the characteristics described herein, is fixed to said collector.
  • this collector is adapted to the circulation of a very high pressure fluid of the CO 2 type.
  • the present invention relates to a heat exchanger for exchanging heat between two fluids, in particular for motor vehicles, comprising at least one collector and / or a flange according to the characteristics described above.
  • the present invention applies to all types of exchanger comprising at least one manifold including at least two inlet / distribution chambers of a heat transfer fluid.
  • the collector chosen to illustrate the invention represented on the figure 5 , a collector plate 1, an intermediate plate 2 and a cover 3 which here comprises two arches 4, 4 'so as to create two fluid circulation chambers 5 and 6.
  • the invention applies to a manifold of different structure, always having a plurality of flow chambers 5, 6, for example a manifold, or manifold, made in one piece.
  • the lid 3 has a flat upper surface 7 located respectively at its two ends, or lateral sides intended to allow optimum crimping of protuberances, or teeth 8, extending from the collector plate 1 in order to bind / fix the elements 1, 2 and 3 together.
  • Each arch 4, 4 ' consists essentially of a semicircle so that their section fits in a circle so as to best withstand the pressure of the supercritical fluid, CO 2 or the like.
  • the tubing 9 conventionally consists of a hollow cylinder with a thick wall, still for holding at high pressures.
  • the flange 10 constitutes, punctually, that is to say only where the flange 10 is attached to the collector, the tops of the arches 4, 4 'and the upper part of the lid 3.
  • the flange 10 comprises in particular the flat surfaces 7 so that the flange is fixed to the lid 3, to the intermediate plate 2 and to the collector plate 1 mainly by crimping the teeth 8 on these parts 7.
  • the flange 10 comprises a housing portion 11 intended to receive and accommodate the end of the tubing 9.
  • This housing portion 11 obviously has a geometry adapted to or equivalent to that of the end of the tubing 9.
  • the pipe 9 extends vertically, that is to say perpendicularly to the longitudinal axis of the collector and extending in the plane defined by the two circulation channels 12, 12 'of the flange 10.
  • the angle between the two channels 5, 6 will ideally be between 60 ° and 120 °.
  • the tubing 9 extends parallel to the manifold so that the tubing 9, and therefore the circulation of the fluid inside, extends perpendicularly to the plane defined by the two circulation channels 12, 12 'of the flange 10. It will be possible to provide that the inner end of the tubing 9 has a curved portion bringing the fluid to the inlet of the tubing 9.
  • tubing 9 extends horizontally, that is to say it has an axis perpendicular to the longitudinal axis of the collector and is in the plane defined by the two circulation channels 12, 12 'of the flange 10.
  • the angle between the two channels 5, 6 will be considerably less than 90 °, preferably between 30 ° and 80 °.
  • the figure 6 illustrates the flow of the fluid in the circulation channels 12, 12 'of the flange 10, the main common flow, at the level of the pipe 9, and that of each of the two channels 12 and 12', and the balanced distribution of the fluid between the two channels 12, 12 '. It is clearly seen in this figure that the fluid flow in each of the two channels 12, 12 'is optimized.
  • the two channels 12, 12 ' may have a linear section, as shown in the accompanying figures.
  • these two channels 12, 12 ' have different end sections, for example sections substantially parallel to each other, while retaining the two aspects of the invention which are the absence of a chamber / part dedicated to receiving the fluid from the tubing 9 and producing a plurality of channels 12, 12 'extending from the inlet port of the flange 10, extending substantially linearly and forming between an angle strictly less than the flat angle (180 °).
  • the invention makes it possible to distribute in a particularly equitable manner the flow rate in the two distribution channels 12, 12 'of the flange 10 so that the fluid occupies substantially equally the different chambers 5, 6 of the collector.
  • the invention thus allows a "self-balancing" flow rates in each chamber 5, 6 without having to resort to variations in diameter.
  • the design, or the "Design”, of Y-distribution of the flange 10 also allows an optimization in terms of size, thus avoiding the counter drilling.
