Definitions

  • the invention relates to the field of heat exchangers and in particular to exchangers intended to be traversed by a fluid under high pressure.
  • the invention relates more particularly to air conditioning evaporators capable of being traversed by a refrigerant fluid in the supercritical state, as is the case with natural gases such as carbon dioxide or CO 2 .
  • air conditioning evaporators capable of being traversed by a refrigerant fluid in the supercritical state, as is the case with natural gases such as carbon dioxide or CO 2 .
  • Such exchangers find particular application in motor vehicles.
  • Collection boxes generally obtained by brazing, which are designed to withstand such high pressures, are already known.
  • the manifold is formed from an extruded hollow section in which are arranged slots for receiving the tubes of the heat exchanger bundle.
  • This solution requires machining a massive extruded profile to allow insertion of the tubes. Then, it does not allow to add a solder plating on the inside to allow good solderability.
  • JP 2000-337788 discloses a manifold composed of a stamped collector plate and an extruded lid. Flat tubes are introduced through openings in the header plate.
  • JP 2003-075024 discloses a three-part header, comprising a header plate, a cover and an intermediate plate used for dispensing the fluid.
  • the collector plate is made by stamping and the tubes are introduced into collars of the collector plate which protrude inside the collector box. Because the ends of the tubes protrude inside the manifold, the interior volume thereof can not be minimized.
  • JP 2002-041332 shows an embodiment similar to the previous one which has the same disadvantage of the fact that the ends of the tubes must protrude inside the manifold.
  • Another solution known by EP 0 563 471 relates to a multi-part manifold in which the tubes do not protrude into the manifold.
  • the brazing between the tubes and the collector plate is made in the thickness of the collector plate.
  • This solution requires an additional plate to stop the ends of the tubes.
  • the surface in contact with the ends of the tubes does not have solder plating.
  • This veneer comes from remainder of the collector plate and / or the stop plate. As a result, the weight of this part is not optimized.
  • the object of the invention is in particular to overcome the aforementioned drawbacks.
  • a heat exchanger collector box comprising a collector plate provided with openings for the insertion of heat exchange tubes, a distribution plate contiguous to the collector plate and delimiting chambers communicating with the heat exchange tubes. tubes, and a lid to close the chambers of the distribution plate.
  • the collector plate is a stamped plate having a flat inner face for receiving the distribution plate, while the distribution plate has a flat inner face adapted to come into contact with the flat inner face of the collector plate forming abutment stop for the tubes.
  • Such a manifold is particularly suitable for heat exchangers traversed by a fluid under high pressure, in particular to air-conditioning evaporators suitable for being traversed by a refrigerant fluid in the supercritical state, in particular by CO 2 .
  • the use of a stamped collector plate avoids machining operations.
  • the header plate and the distribution plate are in mutual contact with flat surfaces, this allows a good brazed connection on brazed surfaces. important.
  • the tubes are stopped by the distribution plate and can not project into the manifold.
  • the collector plate has an outer face from which flanges for receiving the tubes extend.
  • each of the collars envelops the entire periphery of the tube which it receives and comprises a chamfer favoring the introduction of the tube.
  • the collector plate has a given thickness, delimited between the inner face and the outer face, and each of the collars extends over a height, from the inner face, which is greater than the thickness of the collecting plate.
  • the apertures and collars of the header plate have internal generally rectangular shaped sections for receiving flat tubes of homologous outer section.
  • the header plate comprises two rows of openings and collars for receiving two rows of tubes.
  • crimping members come from the header plate to bear on the cover by enclosing the distribution plate for soldering assembly.
  • the presence of crimping members on the header plate allows a temporary assembly of components before soldering.
  • the invention in another aspect, relates to a heat exchanger comprising a bundle of tubes and at least one header as defined above.
  • this heat exchanger is in the form of an evaporator for an air conditioning circuit traversed by a high-pressure refrigerant, in particular a refrigerant fluid operating in the supercritical state.
  • FIG. 1 which shows a heat exchanger 10 having a beam 12 mounted between an upper manifold 14 and a lower manifold 16, the heat exchanger is considered in a vertical position.
  • the beam 12 is composed of two rows of tubes 18 (only one of which is visible in FIG. 1) and corrugated inserts 20 common to both rows of tubes.
  • the manifold 14 is provided with two pipes 22 and 24 respectively for the admission and evacuation of a fluid passing through the tubes of the bundle.
  • the heat exchanger 10 is in the form of an evaporator capable of being traversed by a refrigerant fluid operating in the supercritical state, in particular CO 2 , the pressure of which can reach values of order of 100 to 150 bar.
  • This fluid exchanges heat with a flow of air that scans the tube bundle to produce a flow of air conditioning, especially in a motor vehicle.
  • FIG. 2 shows an exploded view of the heat exchanger of Figure 1. It is seen that the manifold 14 has a manifold plate 26 provided with openings 28 for receiving the tubes of the beam.
  • the openings 28 are of elongate shape and arranged in two rows corresponding to the two rows of tubes.
  • the collecting plate 26 is generally rectangular in shape and comprises, along its two long sides, crimping members 30. It comprises a extension 32 in which are provided openings 34 and 36 for the respective mounting of the tubes 22 and 24.
  • a distribution plate 38 having two rows of slots 40 each communicating with a tube 18 and a row of slots 42 of greater width which each communicate with two adjacent tubes belonging to the two rows of the beam. Slots 40 and 42 contribute to defining chambers which allow the distribution of the fluid and its circulation in the tubes of the bundle along a defined path.
  • a cover 44 intended to be held against the collector plate, trapping the distribution plate 38, under the action of the crimping members 30.
  • the lower manifold 16 is made in a similar manner except that it has no extension. It consists of a header plate 46, a distribution plate 48 and a cover 50. Note that the distribution plate 48 has two rows of slots 52 each communicating with a tube of the beam at its lower part.
  • FIG. 3 shows a half-view in cross section of the manifold 14 relative to a plane of symmetry P.
  • the manifold has a symmetrical portion to the right of the plane of symmetry P .
  • FIG. 3 shows the collecting plate 26, the distribution plate 38 and the cover 44.
  • the collecting plate 26 is a stamped plate having a planar inner face 54 for receiving the distribution plate 38 and an outer face 56 for from which extend collars 58 respectively surrounding the openings 28 for receiving the tubes.
  • Each of the collars 58 has a chamfer 59 envelopes 1 all of the tube 18 that it receives and further comprises a chamfer 59 oriented to promote the introduction of the tube.
  • the outer face 56 is directed downwards and the collars 58 are also directed downwards. These collars are thus arranged in two rows corresponding to the two rows of openings 28.
  • the collars and the openings have a rectangular general section to allow the reception of flat tubes 18 having a homologous external section, as it is will be seen later with reference to FIG.
  • the collecting plate 26 has a given thickness E delimited between its inner face 54 and its outer face 56, and each of the collars 58 extends over a height H, from the outer face, which is greater than the thickness E the collector plate (see Figure 4).
  • the thickness E may be of the order of 1 to 2 mm and the height H at least equal to this value.
  • the crimping members 30 are, as already indicated, formed along the two long sides of the collecting plate 26. They are in the form of a folded, slot-shaped edge with a number of tabs or teeth 60 ( Figure 3). These tabs also appear in the folded state in FIG. 1 and in the unfolded state in FIG. 2.
  • the distribution plate 38 has a flat inner face 62 adapted to come into contact with the flat inner face 54 of the header plate and an outer face 64 generally flat, opposite, adapted to receive the cover 44.
  • the distribution plate 38 has a thickness E ' given, delimited between its outer face 64 and its inner face 62, which is substantially equal to the thickness E of the header plate ( Figure 4).
  • the slots 40 and 42 In the thickness of the distribution plate, are arranged the slots 40 and 42 above. In Figure 3 we see half of one of the slots, in this case a slot 42 which communicates with two adjacent tubes respectively belonging to the two rows of tubes of the beam. At the same time, the distribution plate 38 forms an insertion stop for the tubes as can be seen in FIG. 3. As a result, the respective ends of the tubes can not exceed the plane defined by the inner face 54 of the collector plate.
  • the cover 44 is made here in the form of a stamped part having a peripheral edge 66 (FIG. 3) for supporting the crimping members 30.
  • the cover could also be made in the form of an extruded part or forged or machined.
  • the lid 44 comprises, as seen on the half-section of Figure 3, a series of bosses 68, six in number along the width, three of these bosses appear on the half-section of Figure 3.

  • the cover 44 is formed of a plurality of arches or jambs having the same shapes and dimensions. As can be seen in FIG. 3, the arches located along a large side of the collector have the same shapes and dimensions as the other arches but to which, on its outer face, was added a foot of material whose height is greater than the height of the chambers 70. This foot of material provides a larger surface for crimping and contact between the cover 44, the plate of distribution 38 and the manifold plate 26 so that this crimping, intended to assemble and fix said elements 26, 38 and 44, is particularly robust and effective.
  • the crimping tabs or teeth 60 once crimped or placed on the peripheral edge 66 of the cover 44, extend beyond the chambers 70 so that the ends of the collector plate 26 have a C-shaped profile. framing or enclosing the distribution plate 38 and the chambers 70 formed by the cover 44. In this way, the assembly formed by the header plate 26, the distribution plate 38 and the cover 44 forms a compact and resistant whole.
  • the tabs or teeth 60 crimped onto the cover 44 have an inner planar surface in contact with the outer flat surface of the peripheral edge 66 so that said tabs 60 extend parallel to the distribution plate and to the defined lower plane. by the flat inner surface 54 of the header plate 26.
  • the tabs 60 operate a force, plane to plane, perpendicular to the aforesaid parallel planes of extension of the cover 44 and the distribution plate 38 so that the assembly formed of the manifold plate 26, the distribution plate 38 and the cover 44 is extremely strong and strong.
  • bosses are suitably arranged to allow the refrigerant fluid to penetrate inside the manifold 14 via the manifold 22, then circulate in the tubes of the bundle between the manifold 14 and the manifold 16 and leave the exchanger over there
  • the way in which the circulation of the fluid takes place in the bundle will not be described in detail, as it is a provision in itself known to those skilled in the art.
  • the cover 44 has a generally rectangular shape, the bosses 68 extending in the direction of the length of the cover. As already indicated, the cover has a plurality of bosses 68 in the width direction. In the example shown, six bosses are present in the direction of the width.

  • a metallic material preferably aluminum alloy
  • the fact of making several bosses makes it possible to form chambers 70 of small volume limiting the effect of the pressure of the fluid on the components of the header plate.
  • solder plating 72 is provided on the inside face 54 of the collector plate, as can be seen in FIG. 4. It is furthermore advantageous to provide solder plating at the interface between the distribution plate and lid.
  • This veneer may be placed either on the outer face 64 of the distribution plate 38, or on the inner face 74 of the cover 44 which is applied against the distribution plate.
  • the entire heat exchanger can be assembled.
  • the components of the bundle 12 (tubes and spacers) are arranged against each other and the ends of the tubes are placed, on one side, in the openings of the manifold 14 and, on the opposite side, in the openings of the box collector 16.

  • solder plating 72 from the inner face of the header plate provides a connection between the header plate and the distribution plate and a connection between the tubes and the collars. Moreover, a connection is ensured between the plate of distribution and the lid thanks to the solder plating provided at their interface.
  • FIG. 5 shows, in cross-sectional view, a tube 18 of the beam. It can be seen that this tube has a generally rectangular shape with two large parallel faces 76 and two small opposite faces 78.
  • the tube comprises a plurality of parallel channels 80 and is advantageously made by extrusion.
  • the manifold 16 is made in a similar manner to the manifold 14, except that it does not have an extension for mounting fluid inlet and outlet tubing.
  • the manifold of the invention is capable of many variants. It finds a main application to heat exchangers traversed by a high-pressure refrigerant, in particular to air-conditioning evaporators traversed by a fluid in the supercritical state such as CO 2 , such as those intended for motor vehicles.
