  • a heat exchange system on the front face of the vehicle, said system comprising in particular a condenser capable of ensuring heat exchange between a refrigerant circulating in the condenser and an incident flow of fresh air coming from the exterior of the vehicle. It is known to produce the condenser in one piece with a series of stacked plates forming between them, on the one hand, sealed circulation ducts for the passage of the refrigerant, and, on the other hand, passages for the passage of air.
  • a known arrangement consists in arranging a first heat exchanger as a condenser and a second heat exchanger, parallel to the first, performing the function of a subcooler, facing a grille opening located on the front face of the vehicle.
  • the condenser and the subcooler are associated with a bottle for storing the refrigerant in the liquid phase.
  • the subcooler makes it possible to subcool the refrigerant at the outlet of the storage bottle.
  • the storage bottle separates the liquid phase from the gas phase of the refrigerant and ensures filtration and dehydration of the refrigerant.
  • a known arrangement for this system consists in placing the storage bottle laterally with respect to the heat exchangers and, on the one hand, in connecting it hydraulically to each of the exchangers via suitable pipes and, on the other hand, in keeping it in place with respect to the heat exchangers via a mechanical assembly securing the bottle to a structural element of the vehicle or to one of the exchangers.
  • the use of a storage bottle in the prior art thus requires numerous mechanical means penalizing the size of the system and making the manufacture and implementation of the heat exchange system on the vehicle complex.
  • the invention falls within this context and seeks to address the abovementioned drawbacks.

  • the heat exchanger has a substantially rectangular, parallelepipedal shape. It comprises a bundle of circulation channels, in particular produced by means of tubes, for the refrigerant, these circulation channels comprising an outlet which is located at a side wall of the heat exchanger.
  • the connection flange is secured, for example by fixing by brazing, at this fluid outlet of the heat exchanger.

  • the transverse mechanical fixing zone may be present at a free end opposite to the end of the connection flange secured by the heat exchanger.
  • the transverse mechanical fixing zone is configured to cooperate with another mechanical fixing zone included on another connection flange of another heat exchanger having properties similar to what has been described previously.
  • the cooperation between the transverse mechanical fixing zones makes it possible to ensure the position of the connection flanges between them and therefore the position of the heat exchangers with respect to one another, in order to ensure a separation between these heat exchangers dimensioned by calculation to allow optimum thermal efficiency in each of the heat exchangers. Moreover, this cooperation can allow the installation of a storage bottle as will be described below.
  • the transverse mechanical fixing zone comprises a bearing surface ensuring cooperation by complementarity of shape with the other connection flange.
  • the transverse mechanical fixing zone able to cooperate with the transverse mechanical fixing zone of the other connection flange has a particular shape allowing a complementarity of shape during the cooperation of the connection flanges. Cooperation takes place by direct contact between the connection flanges, via the bearing surface formed in their respective mechanical fixing zone.
  • the circulation channel is formed of at least two intersecting ducts in communication.
  • the inlet of this circulation channel is positioned opposite one end of the tube bundle where the refrigerant circulates, the position of this inlet of the circulation channel being ensured by the fixing of the connection flange, for example by brazing, to the heat exchanger.
  • the outlet of the circulation channel is located at a wall of the connection flange perpendicular to the wall of the connection flange comprising the inlet of the circulation channel.
  • the circulation channel can optionally comprise three intersecting ducts in communication, in the case where a transverse offset of the circulation channel is necessary before said circulation channel opens out at a wall of the connection flange perpendicular to the wall of the connection flange comprising the inlet of the circulation channel.
  • an intermediate duct located between the first duct and the second duct.
  • the circulation channel opens onto a nozzle forming a projection from a wall of the connection flange and intended to cooperate with a storage bottle.
  • the outlet of the circulation channel of the connection flange is located on a wall perpendicular to the wall of the connection flange comprising the inlet of the circulation channel of the connection flange, more precisely the inlet formed at one end of the first duct.
  • a nozzle protruding from the surface of the connection flange and having a hollow shape is arranged in the axial extension of the second duct of the connection flange.
  • This nozzle is cylindrical in shape and comprises seals on its periphery, advantageously made of flexible material such as rubber, for example.
  • the cylindrical shape of the nozzle is centered around an axis of elongation of the nozzle.
  • the nozzle is intended to be inserted into a circulation orifice of a storage bottle which will be described later.
  • the transverse mechanical fixing zone of the connection flange comprises a through-bore.
  • a bore passes right through the connection flange, in a direction parallel to the axis of elongation of the nozzle of the circulation channel.
  • This bore is configured to receive a fixing means, for example a screw.
  • the through-bore of the connection flange is smooth to ensure the passage of the fixing means which will be screwed to the storage bottle as will be described below, the fixing means making it possible to ensure a function of keeping the connection flange in place with respect to the storage bottle.
  • the invention also consists of a heat exchange system for a vehicle comprising a first heat exchanger and a second heat exchanger constituting a refrigerant circulation circuit, each exchanger conforming to what has been described above, characterized in that a first bearing surface of the first connection flange of the first heat exchanger is in direct contact with a second bearing surface of the second connection flange of the second heat exchanger.
  • the heat exchangers are both of parallelepipedal shape and each have a connection flange on their lateral surface.

  • the first connection flange may have substantially the shape of a block, with the longitudinal portion and the transverse portion having substantially equivalent dimensions while the second connection flange comprises a mainly longitudinal portion, that is to say that the transverse portion of the second connection flange consists of a tab of small dimensions compared with that of the longitudinal portion, the tab forming a projection perpendicular to the longitudinal portion.
  • the tab of the second connection flange forms the second mechanical fixing zone, presenting a bearing surface for the block shape of the first connection flange.
  • the heat exchange system comprises a storage bottle.
  • This storage bottle is connected to the two connection flanges by means which will be described below.

  • the bottom wall of the storage bottle is arranged opposite the connection flanges so that the orifices made in the bottom wall coincide with the positioning of the nozzles of the two connection flanges once the latter are fitted against one another.
  • the nozzles of the connection flanges are therefore each inserted into an orifice present in the bottom wall of the storage bottle, which participates in closing the refrigerant circuit within the heat exchange system.
  • the refrigerant first of all circulates within the first heat exchanger, then in the circulation channel of the connection flange of the first heat exchanger to the storage bottle via the nozzle inserted therein.
  • the refrigerant can therefore circulate in the circulation channel of the second connection flange of the second heat exchanger, then in the bundle of the second heat exchanger itself.
  • the heat exchange system comprises a single fixing means which secures the two connection flanges of the heat exchangers and the storage bottle.
  • the bottom wall of the storage bottle has a third orifice forming a fixing orifice separate from the two circulation orifices receiving the nozzles of the connection flanges.
  • the orifices passing through the connection flanges and the fixing orifice of the storage bottle are aligned, in a coaxial manner, with respect to one another.
  • each of these orifices has an axis of revolution and these different axes of revolution are substantially coincident when the heat exchange assembly is assembled.
  • the fixing orifice is configured to receive the single fixing means.
  • the fixing orifice can for example be threaded if the fixing means is a screw in order to guarantee the retention of this same screw.

  • the connection flanges are configured and dimensioned such that, when the connection flanges cooperate with one another, their respective through-bores face one another.
  • the fixing means can therefore be inserted through each through-bore so as to be able to be inserted afterwards into the fixing orifice opening onto the bottom wall of the storage bottle.
  • the fixing means has a length greater than the sum of the dimensions, in the corresponding direction, of the two transverse mechanical fixing zones so that the end of the fixing means can come out of the through-bores and subsequently be housed within the fixing orifice of the storage bottle.

  • the first nozzle 11 is present substantially in the center of the first connection flange 5 . This first nozzle 11 is therefore slightly offset transversely along a transverse axis T relative to the first heat exchanger 2 .
  • the first connection flange 5 more particularly the first transverse portion 61 , comprises a first transverse mechanical fixing zone 21 .
  • This first transverse mechanical fixing zone 21 comprises in particular, as illustrated by a quadrilateral shape formed by short dotted lines in FIG. 3 , a first bearing surface 19 , the function of which will be explained in detail below, the first bearing surface 19 being located on the lower face of the first connection flange 5 , that is to say the face opposite to the first upper face 31 , at the first transverse portion 61 .
  • the first through-bore 13 passes right through the first connection flange 5 along a vertical axis V.
  • the cylindrical shape of the through-bore 13 is shown in FIG. 3 by transparency in dotted lines.

  • the second connection flange 6 secured to the second heat exchanger 3 , comprises, in a similar way to the above, a second nozzle 12 , of identical appearance to the first nozzle 11 , but which, unlike the latter, is centered on the plane of elongation of the second heat exchanger 3 , without transverse offset along a transverse axis T.
  • connection flange 6 is functionally identical to the first connection flange, and while the second connection flange 6 also comprises a second longitudinal portion 52 and a second transverse portion 62 , arranged in the extension of the second longitudinal portion, this second connection flange 6 has a different shape from the first connection flange 5 .
  • the second longitudinal portion 52 extends along a longitudinal axis L in the plane of elongation of the second heat exchanger 3 .
  • the second longitudinal portion 52 comprises a second upper face 32 , from which the second nozzle 12 projects.
  • the second longitudinal portion 52 also comprises a second transverse end face 72 , facing the first connection flange 5 .
  • the extension along the longitudinal axis L of the second longitudinal portion 52 is of a length identical to the extension along the longitudinal axis L of the first longitudinal portion 51 of the first connection flange 5 of the first heat exchanger 2 .

Indeed, the longitudinal dimension along an axis L is identical between the two connection flanges and their dimensions along a vertical axis V and along a transverse axis T are adapted for cooperation. The cooperation of the flanges with one another is represented in FIG. 3 by mixed dotted lines.
  • the first bearing surface 19 of the first connection flange 5 mentioned above rests on the second bearing surface 20 of the second connection flange 6
  • the first transverse end face 71 rests against the second transverse end face 72 .
  • FIG. 4 is a sectional view of the two connection flanges in cooperation, that is to say in their final position when the heat exchange system is assembled, in a section plane perpendicular to the heat exchangers and passing through the nozzles, this sectional view making visible the arrangement of the circulation channels formed in the structure of the connection flanges. For reasons of clarity, the heat exchangers are not shown in the figure.
  • Each circulation channel has one end located at the braze between the connection flange and the heat exchanger, and another end represented by the nozzle located on each connection flange.
  • first nozzle 11 of the first connection flange 5 is offset transversely with respect to the plane of elongation of the first heat exchanger and therefore with respect to the inlet of the circulation channel of the first connection flange, while the second nozzle 12 of the second connection flange 6 is in alignment with the plane of elongation of the second heat exchanger.
  • the first connection flange 5 comprises a first circulation channel 16 extending from a circular inlet 24 , located on the wall intended to be brazed to the heat exchanger, up to the first nozzle 11 .
  • the refrigerant after having circulated in the heat exchanger, emerges at this circular inlet 24 and flows in liquid/gaseous form within this first circulation channel 16 .
  • the first circulation channel 16 is formed by the succession of three intersecting ducts in fluid communication, including a first duct 161 , an intermediate duct 162 and a second duct 163 .
  • the first duct 161 extends mainly in a longitudinal direction L.
  • the first circulation channel 16 therefore extends subsequently along a transverse axis T, via the intermediate duct 162 .
  • the first circulation channel 16 then extends in a vertical direction V, via the second duct 163 which extends the intermediate duct 162 and opens onto the first nozzle 11 .
  • the second connection flange 6 comprises a second circulation channel 23 extending from the second nozzle 12 to a circular outlet 25 located on the wall intended to be brazed to the second heat exchanger.
  • the refrigerant circulates from the second nozzle 12 to the circular outlet 25 while being guided by the second circulation channel 23 , comprising a third duct 231 and a fourth duct 232 .
  • the second nozzle 12 is centered with respect to the plane of elongation of the second heat exchanger so that the second circulation channel does not require an intermediate duct as described for the first connection flange.
  • the second connection flange 6 therefore comprises two intersecting ducts forming the second circulation channel 23 , the second circulation channel 23 extending along a longitudinal axis L via the third duct 231 and along a vertical axis V via the fourth duct 232 .
  • FIGS. 5 and 6 are views from two different angles of the cooperation of the connection flanges.
  • FIG. 5 is a side view, from a viewing angle coincident with a longitudinal axis L
  • FIG. 6 is a bottom view, from a viewing angle coincident with a vertical axis V.
  • the heat exchangers are not shown here for reasons of clarity.
  • FIG. 5 illustrates more particularly the configuration of the connection flanges when the heat exchange system is assembled and in particular the fact that, on the one hand, the first transverse mechanical fixing zone of the first connection flange 5 bears on the second transverse mechanical fixing zone of the second connection flange 6 by means of direct contact between their respective bearing surface 19 and 20 , and that, on the other hand, a contact plane is also formed by the contact between the first transverse end face 71 and the second transverse end face 72 .
  • a first vertical dimension V 1 corresponds to the vertical dimension of the first connection flange 5 .
  • a second vertical dimension V 2 corresponds to the vertical dimension of the second longitudinal portion of the second connection flange 6 .
  • a third vertical dimension V 3 corresponds to the vertical dimension of the second transverse portion or of the second transverse mechanical fixing zone of the second connection flange 6 , forming a tab projecting from the second transverse end face 72 .
  • the first connection flange 5 of a first vertical dimension V 1 rests on the second transverse mechanical fixing zone of the second connection flange 6 of a third vertical dimension V 3 .
  • the heat exchange system is configured so that the first upper face 31 of the first connection flange 5 and the second upper face 32 of the second connection flange 6 are coplanar and participate in forming the same planar cooperation surface 80 . It follows from the above that the second vertical dimension V 2 is equal to the sum of the first vertical dimension V 1 and of the third vertical dimension V 3 .
  • connection flanges implies that the through-bores of each connection flange 5 , 6 are aligned.
  • a fixing means 15 can be inserted through the two connection flanges 5 and 6 .
  • the fixing means 15 shown here is a screw, but any fixing means capable of being inserted within the bores can be envisioned.
  • the fixing means 15 comprises a head 151 , which bears on the lower wall of the second connection flange 6 , and a shank, the fixing means being dimensioned so that, once inserted into the through-bores, and the head 151 bearing against the lower wall of the second connection flange, the shank protrudes beyond the planar cooperation surface 80 , here at the upper face of the first connection flange, so as to be able to be inserted into a fixing orifice of the storage bottle.
  • FIG. 6 makes more particularly visible the head of the fixing means 15 as well as the arrangement of the transverse mechanical fixing zones of the connection flanges 5 and 6 with respect to one another.
  • This viewing angle makes it possible to observe that the first connection flange 5 comprises a chamfer 26 , also visible in FIG. 5 , at the junction edge between the lower face and the first transverse end face 71 , that is to say the edge able to face the junction between the second transverse end face 72 of the second connection flange and the tab which projects from this second face and which forms the second mechanical fixing zone.
  • This chamfer 26 makes it possible to limit the mechanical interference which may occur during the cooperation between the connection flanges 5 and 6 .
  • FIG. 7 more particularly represents the storage bottle 4 .
  • the storage bottle 4 is cylindrical or substantially cylindrical in shape.
  • the storage bottle 4 comprises a bottom wall 28 . It is this bottom wall 28 which will interact with the connection flanges.
  • the bottom wall 28 comprises three orifices: two circulation orifices 17 and one fixing orifice 18 which corresponds to the fixing orifice mentioned above and capable of cooperating with the shank of the fixing means 15 .
  • the circulation orifices 17 are able to receive respectively the first nozzle of the first connection flange 5 and the second nozzle of the second connection flange 6 .
  • the circulation orifices 17 therefore have a diameter suitable for receiving the nozzles of the connection flanges, taking into account any seals which may be included at the nozzles.
  • the center distance between the circulation orifices 17 is substantially equal to the center distance between the nozzles when the connection flanges cooperate with one another with the transverse end faces 71 , 72 of each connection flange in contact.
  • the fixing hole 18 is also present at the bottom wall 28 .
  • the fixing orifice 18 is opposite the through-bores superposed on one another.
  • the fixing orifice 18 is suitable for receiving the fixing means, which therefore passes through each of the connection flanges before being secured to the storage bottle. If the fixing means is for example a screw, the fixing orifice 18 is threaded.
  • the fixing means is for example a screw, the fixing orifice 18 is threaded.
  • FIG. 8 is a sectional view of the connection flanges and of the storage bottle when they are secured to one another. For reasons of clarity of the figure, the heat exchangers and the fixing means are not shown.
  • first connection flange 5 and the second connection flange 6 cooperate with each other via their bearing surface and their respective transverse end face.
  • the first through-bore 13 and the second through-bore 14 face one another and thus participate in forming a continuous through-bore.
  • the storage bottle 4 is arranged at the planar cooperation surface 80 , resulting from the cooperation of the connection flanges 5 and 6 , so that the fixing orifice 18 of the storage bottle 4 is opposite the bores 13 and 14 . This position is obtained in particular by inserting the nozzles of the flanges into the circulation orifices of the storage bottle (not visible in this FIG. 8 ).
  • the fixing means is inserted through the end of the second through-bore 14 and along a vertical axis V.
  • the shank of the fixing means therefore passes through the second through-bore 14 , then through the first through-bore 13 up to within the fixing orifice 18 of the storage bottle 4 .
  • the shank of the fixing means must therefore be long enough to pass through all of the bores 13 and 14 and to extend over a substantial length of the fixing orifice 18 .
  • the bores 13 and 14 are smooth in order to ensure the passage of the shank of the fixing means without mechanical interference, while the fixing orifice 18 of the storage bottle 4 , on the other hand, comprises a means for mechanically retaining the fixing means, for example an internal thread if said fixing means is a screw.
  • FIG. 8 also makes it possible to demonstrate the importance of the chamfer 26 in order to avoid mechanical interference. As illustrated, the latter is opposite a fillet 27 (also visible in FIG. 5 ) included at the second connection flange 6 , at the junction between the second transverse end face of the second connection flange and the tab which projects from this second face and which forms the second mechanical fixing zone.
  • a fillet 27 also visible in FIG. 5
  • FIG. 9 is a view of the heat exchange system 1 as a whole, illustrating the interchangeability of the connection flanges. Indeed, FIG. 9 is identical to FIG. 1 , except for the fact that the first connection flange 5 as described above is located on the second heat exchanger 3 , and the second connection flange 6 as previously described is located on the first heat exchanger 2 .
  • the shape of the connection flanges does not depend on the heat exchanger to which the connection flange is brazed. According to the invention, it is important to have two flanges respectively configured to ensure the passage of fluid between the heat exchangers 2 and 3 and the storage bottle 4 , and to cooperate with each other by complementarity of shapes.
  • connection flanges 5 and 6 can therefore also vary, as long as they have a complementarity between them making it possible to obtain a planar cooperation surface to accommodate the storage bottle 4 as well as through-bores aligned during the cooperation of the flanges so that they can allow the passage of a single fixing means making it possible to secure the connection flanges and the storage bottle in a single operation.
  • connection flanges can be modified without harming the invention, insofar as they perform the functions described in the present document.
