Description

Condenseur pour circuit de climatisation avec bouteille intégrée Condenser for air conditioning circuit with integrated bottle

L'invention se rapporte au domaine des circuits de climatisation .The invention relates to the field of air conditioning circuits.

Elle concerne plus particulièrement un condenseur, notamment pour un circuit de climatisation de véhicule automobile, comprenant un premier bloc d'échange de chaleur pour assurer le refroidissement d'un fluide frigorigène jusqu'à sa condensation au moyen d'un fluide de refroidissement, un deuxième bloc d'échange de chaleur pour assurer le sous-refroidissement du fluide frigorigène au moyen d'un fluide de refroidissement, ainsi qu'une bouteille interposée entre le premier bloc et le deuxième bloc et propre à être traversée par le fluide frigorigène.It relates more particularly to a condenser, in particular for a motor vehicle air conditioning circuit, comprising a first heat exchange unit for cooling a refrigerant until it is condensed by means of a cooling fluid, a second heat exchange block for subcooling the refrigerant by means of a cooling fluid, and a bottle interposed between the first block and the second block and adapted to be traversed by the refrigerant.

Le terme « bouteille » désigne ici un réservoir intermédiaire qui permet d'assurer la filtration et la déshydratation du fluide frigorigène et aussi de compenser les variations de volume du fluide frigorigène et d'assurer la séparation des phases liquide et gazeuse.The term "bottle" here designates an intermediate reservoir which makes it possible to ensure filtration and dehydration of the refrigerant and also to compensate for variations in the volume of the refrigerant and to ensure the separation of the liquid and gaseous phases.

On connaît déjà, d'après FR 2 846 733, un condenseur de ce type qui intègre une bouteille indémontable brasée entre le premier bloc et le deuxième bloc d'échange de chaleur, lesquels sont formés chacun par des séries de plaques empilées .According to FR 2 846 733, a condenser of this type is already known which integrates an unreturnable bottle brazed between the first block and the second heat exchange block, which are each formed by series of stacked plates.

II en résulte la nécessité de braser un module complet comprenant le premier bloc (condenseur principal) , la bouteille et le deuxième bloc (condenseur additionnel) . En outre, la bouteille doit être équipée après cette opération. Le brasage en une seule fois du module complet est très complexe à réaliser en raison de la masse compacte de l'alliage métallique, généralement à base d'aluminium, qui est engagée dans cette opération.This results in the need to solder a complete module comprising the first block (main condenser), the bottle and the second block (additional condenser). In addition, the bottle must be equipped after this operation. Brazing at one time the complete module is very complex to achieve because of the compact mass of the metal alloy, usually aluminum-based, which is engaged in this operation.

Par ailleurs, en cas de défaillance de l'un des deux blocs ou de la bouteille, le module complet doit être changé.Moreover, in case of failure of one of the two blocks or the bottle, the complete module must be changed.

Il est certes envisageable de réaliser un tel condenseur avec une bouteille rapportée, mais cela nécessite d'utiliser des tubulures de liaison encombrantes entre les blocs et la bouteille. Cela nécessite donc deux interfaces supplémentaires pour lier les deux blocs du condenseur.It is certainly possible to make such a condenser with a reported bottle, but it requires the use of bulky connection pipes between the blocks and the bottle. This requires two additional interfaces to link the two blocks of the condenser.

L'invention a notamment pour but de surmonter les inconvénients précités.The object of the invention is in particular to overcome the aforementioned drawbacks.

Selon un premier aspect inventif, la présente inventionAccording to a first inventive aspect, the present invention

Par ailleurs, selon un second aspect inventif éventuellement distinct du premier aspect inventif ci- dessus, la présente invention propose également un condenseur du type défini en introduction, dans lequel la bouteille est fixée de manière démontable entre le premier bloc et le deuxième bloc par l'intermédiaire respectivement d'une première bride et d'une deuxième bride formant en même temps des interfaces pour la circulation du fluide frigorigène.Furthermore, according to a second inventive aspect possibly distinct from the first inventive aspect above, the present invention also proposes a condenser of the type defined in the introduction, in which the bottle is removably fixed between the first block and the second block by the intermediate respectively of a first flange and a second flange at the same time forming interfaces for the circulation of the refrigerant.

Ces brides permettent ainsi d'assurer non seulement la liaison mécanique entre la bouteille et les deux blocs, mais aussi la circulation du fluide frigorigène. La bouteille forme alors un support pour les deux corps du condenseur. Du fait qu'elle est fixée de manière démontable aux deux blocs du condenseur, elle peut être pré-équipée avant d'être reliée aux deux blocs du condenseur, ce qui simplifie les opérations de montage. Par ailleurs, du fait que l'ensemble est démontable, il est possible de remplacer seulement une partie du condenseur en cas de défaillance de l'un des deux blocs ou de la bouteille.These flanges thus make it possible to ensure not only the mechanical connection between the bottle and the two blocks, but also the circulation of the refrigerant. The bottle then forms a support for the two bodies of the condenser. Because it is removably attached to the two condenser blocks, it can be pre-equipped before being connected to the two condenser blocks, which simplifies assembly operations. Moreover, because the assembly is removable, it is possible to replace only a portion of the condenser in case of failure of one of the two blocks or the bottle.

Dans la description qui suit, faite seulement à titre d'exemple, on se réfère aux dessins annexés, sur lesquels :In the description which follows, made only by way of example, reference is made to the appended drawings, in which:

On se réfère conjointement aux figures 1 et 3 à 5 qui montrent un condenseur 10 destiné notamment à faire partie d'un circuit de climatisation (non représenté} d'un véhicule automobile.FIGS. 1 and 3 to 5, which show a condenser 10 intended in particular to form part of an air conditioning circuit (not shown) of a motor vehicle, are referred to.

Dans un tel circuit, le fluide frigorigène traverse en boucle fermée un compresseur, le condenseur, un détendeur et un évaporateur avant de regagner le compresseur, et ainsi de suite. Dans l'exemple, le condenseur est destiné avant tout à fonctionner avec un fluide frigorigène susceptible d'être présent sous une forme liquide et sous une forme gazeuse. Il peut s'agir notamment d'un fluide fluoré tel que celui connu sous l'appellation R 134a.In such a circuit, the refrigerant passes through a closed loop compressor, the condenser, a pressure reducer and an evaporator before returning to the compressor, and so on. In the example, the condenser is primarily intended to operate with a refrigerant capable of being present in a liquid form and in a gaseous form. It may be in particular a fluoro fluid such as that known under the name R 134a.

Le condenseur comprend un premier bloc 12 d'échange de chaleur pour assurer le refroidissement du fluide frigorigène jusqu'à sa condensation au moyen d'un fluide de refroidissement, un deuxième bloc 14 d'échange de chaleur pour assurer le sous-refroidissement du fluide frigorigène au moyen d'un fluide de refroidissement, ainsi qu'une bouteille 16 interposée entre les blocs 12 et 14 et qui est propre à être traversée par le fluide frigorigène. Le fluide frigorigène en phase gazeuse provenant du compresseur, est d'abord refroidi jusqu'à sa condensation dans le premier bloc 12, il traverse ensuite la bouteille 16, où il est filtré et déshydraté, puis le deuxième bloc 14 qui assure le sous-refroidissement du fluide frigorigène préalablement condensé.The condenser comprises a first heat exchange block 12 for cooling the refrigerant until it is condensed by means of a cooling fluid, a second heat exchange block 14 for sub-cooling the fluid. refrigerant by means of a cooling fluid, and a bottle 16 interposed between the blocks 12 and 14 and which is adapted to be traversed by the refrigerant. The refrigerant gas phase from the compressor, is first cooled until it is condensed in the first block 12, it then passes through the bottle 16, where it is filtered and dehydrated, then the second block 14 which ensures the sub- cooling the condensed refrigerant.

La bouteille 16 est fixée de manière démontable entre le premier bloc 12 et le deuxième bloc 14 par l'intermédiaire respectivement d'une première bride 18 et d'une deuxième bride 20. Ces deux brides assurent non seulement la fixation mécanique de la bouteille entre les blocs 12 et 14, mais elles forment en même temps des interfaces pour la circulation du fluide frigorigène, c'est-à-dire pour passer du premier bloc 12 dans la bouteille 16 et ensuite de la bouteille au deuxième bloc 14.The bottle 16 is removably attached between the first block 12 and the second block 14 via respectively a first flange 18 and a second flange 20. These two flanges not only ensure the mechanical fixing of the bottle between the blocks 12 and 14, but at the same time they form interfaces for the circulation of the refrigerant, that is to say to pass from the first block 12 into the bottle 16 and then from the bottle to the second block 14.

Le premier bloc 12 et le deuxième bloc 14 comprennent chacun une série de plaques empilées 26, respectivement 28 (figure 3) . Ces plaques empilées forment des lames de circulation pour le fluide frigorigène qui alternent avec des lames de circulation pour le fluide de refroidissement. Les plaques 26 du corps 12 sont comprises entre une première plaque d'interface 30 dont est issue la première bride 18 et une première plaque d'extrémité 32 à l'opposé de la première plaque d'interface 30. De même, les plaques 28 du corps 14 sont comprises entre une deuxième plaque d'interface 34 dont est issue la deuxième bride 20 et une deuxième plaque d'extrémité 36 à l'opposé de la deuxième plaque d'interface 34.The first block 12 and the second block 14 each comprise a series of stacked plates 26, respectively 28 (Figure 3). These stacked plates form circulation slats for the refrigerant which alternate with circulation slats for the coolant. The plates 26 of the body 12 are between a first interface plate 30 from which is derived the first flange 18 and a first end plate 32 opposite the first interface plate 30. Similarly, the plates 28 of the body 14 are included between a second plate interface 34 from which the second flange 20 and a second end plate 36 emerge opposite the second interface plate 34.

Dans l'exemple la plaque d'interface 30 est réalisée d'une seule pièce avec la bride 18 et, de même, la plaque d'interface 34 est réalisée d'une seule pièce avec la bride 20, par exemple par moulage et usinage d'un alliage à base d'aluminium.In the example, the interface plate 30 is made in one piece with the flange 18 and, likewise, the interface plate 34 is made in one piece with the flange 20, for example by molding and machining. an aluminum-based alloy.

La plaque d'extrémité 32 porte une bride de raccordement 38 pour l'entrée du fluide frigorigène à condenser, tandis que la plaque d'extrémité 36 porte une bride de raccordement 40 pour la sortie du fluide frigorigène condensé et sous refroidi . La condensation du fluide frigorigène dans le premier bloc 12 s'effectue par échange de chaleur avec un fluide de refroidissement qui pénètre dans le bloc 12 par une tubulure d'entrée 42 et en ressort par une tubulure de sortie 44. Dans l'exemple les tubulures 42 et 44 sont disposées respectivement en haut et en bas du bloc 12 et la bride 38 en bas du bloc 12 (figure 6) .The end plate 32 carries a connection flange 38 for the entry of the refrigerant to be condensed, while the end plate 36 carries a connection flange 40 for the output of the condensed and cooled refrigerant. The condensation of the refrigerant in the first block 12 is effected by heat exchange with a cooling fluid which enters the block 12 through an inlet pipe 42 and leaves it through an outlet pipe 44. In the example, tubing 42 and 44 are respectively disposed at the top and bottom of the block 12 and the flange 38 at the bottom of the block 12 (Figure 6).

Le fluide frigorigène préalablement condensé est sous- refroidi dans le bloc 14 par échange de chaleur avec le fluide de refroidissement qui pénètre à l'intérieur du corps 14 par une tubulure d'entrée 46 et quitte ensuite le corps 14 par une tubulure de sortie 48. Dans l'exemple les tubulures 46 et 48 sont disposées respectivement en bas et en haut du bloc 14 et la bride 408 en bas du bloc 12 (figures 1 et 6) .The previously condensed refrigerant is subcooled in the block 14 by heat exchange with the cooling fluid which enters the body 14 through an inlet pipe 46 and then leaves the body 14 through an outlet pipe 48 In the example, the tubes 46 and 48 are arranged respectively at the bottom and at the top of the block 14 and the flange 408 at the bottom of the block 12 (FIGS.

La tubulure d'entrée 42, la tubulure de sortie 44 et la bride de raccordement 38 sont portées par le premier bloc 12 d'échange de chaleur et plus particulièrement par la plaque d'extrémité 32.The inlet pipe 42, the outlet pipe 44 and the connecting flange 38 are carried by the first block 12 of heat exchange and more particularly by the end plate 32.

De manière correspondante, la tubulure d'entrée 46, la tubulure de sortie 48 et la bride de raccordement 40 sont portées par le deuxième corps 14 et plus particulièrement par la plaque d'extrémité 36.Correspondingly, the inlet pipe 46, the outlet pipe 48 and the connecting flange 40 are carried by the second body 14 and more particularly by the end plate 36.

Dans l'exemple de réalisation, la bride de raccordement 38 est réalisée d'une seule pièce avec la plaque d'extrémité 32, tandis que les tubulures 42 et 44 sont rapportées. De même, la bride de raccordement 40 est réalisée d'une seule pièce avec la plaque d'extrémité 36, tandis que les tubulures 46 et 48 sont rapportées sur cette dernière.In the exemplary embodiment, the connecting flange 38 is made in one piece with the end plate 32, while the pipes 42 and 44 are attached. Similarly, the connecting flange 40 is made in one piece with the end plate 36, while the pipes 46 and 48 are reported on the latter.

Les corps 12 et 14 d'échange de chaleur sont réalisés selon la technique bien connue des échangeurs de chaleur à plaques. Il ne paraît donc pas utile de décrire ici en détail la réalisation des plaques 26 et 28. Il s'agit de plaques empilées par paires délimitant des lames de circulation pour le fluide frigorigène qui alternent avec des lames de circulation pour le fluide de refroidissement. La structure de ces lames apparaît sur la coupe de la figure 3. Les corps 12 et 14 sont réalisés chacun par brasage de leurs composants, de préférence en une seule opération.The bodies 12 and 14 of heat exchange are made according to the well known technique of plate heat exchangers. It therefore does not seem useful to describe here in detail the production of the plates 26 and 28. These are plates stacked in pairs delimiting circulation blades for the refrigerant which alternate with the circulation blades for the cooling fluid. The structure of these blades appears on the section of Figure 3. The bodies 12 and 14 are each made by brazing their components, preferably in a single operation.

La première bride 18 et la deuxième bride 20 sont propres à être fixées de manière démontable sur une partie réceptrice 50 de la bouteille 16. Dans l'exemple de réalisation, la partie réceptrice 50 est un couvercle d'extrémité de forme générale circulaire qui vient coiffer un corps 52 de forme générale cylindrique circulaire de la bouteille. Dans l'exemple, ce couvercle d'extrémité est brasée sur le corps 52, la bouteille 16 étant ainsi rendue indémontable en elle-même. Le corps 12 se termine par un fond conique 54. Le couvercle d'extrémité 50 est fixé sur une extrémité ouverte du corps 52, à l'opposé du fond conique 54, en maintenant un tube axial 56 qui s'étend suivant la direction axiale XX de la bouteille.The first flange 18 and the second flange 20 are adapted to be removably attached to a receiving portion 50 of the bottle 16. In the exemplary embodiment, the receiving portion 50 is a generally circular end cap that comes to cap a body 52 of generally cylindrical circular shape of the bottle. In the example, this end cover is soldered to the body 52, the bottle 16 being thus made indémontable in itself. The body 12 terminates in a conical bottom 54. The end cap 50 is fixed on one end open body 52, opposite the conical bottom 54, maintaining an axial tube 56 which extends in the axial direction XX of the bottle.

Ge tube 56 comporte une collerette 58 qui permet de maintenir en position une cartouche filtrante et dessicante 59 disposée entre le couvercle d'extrémité 50 et la collerette de retenue 58.The tube 56 comprises a flange 58 which makes it possible to hold in position a filtering and desiccating cartridge 59 disposed between the end cap 50 and the retaining flange 58.

Le tube 56 comporte une extrémité inférieure 60 qui s'engage dans une bague 62 maintenue dans la région centrale du fond 54 et qui peut laisser passer le fluide frigorigène. Le tube comporte en outre une extrémité supérieure 64 qui est maintenue dans un logement axial du couvercle d'extrémité 50.The tube 56 has a lower end 60 which engages in a ring 62 held in the central region of the bottom 54 and which can pass the refrigerant. The tube further comprises an upper end 64 which is held in an axial housing of the end cap 50.

La direction axiale XX constitue l'axe longitudinal de la bouteille et aussi l'axe de révolution du corps 52.The axial direction XX constitutes the longitudinal axis of the bottle and also the axis of revolution of the body 52.

La première bride 18 comprend un alésage de sortie 66 propre à venir dans le prolongement d'un alésage d'entrée 68 de la partie réceptrice (couvercle 50) de la bouteille suivant une première direction d'alignement Dl (figure 4) . De façon correspondante, la deuxième bride 20 comprend un alésage d'entrée 70 propre à venir dans le prolongement d'un alésage de sortie 72 de la partie réceptrice (couvercle 50) de la bouteille suivant une deuxième direction d'alignement D2 (figure 4) .The first flange 18 comprises a clean output bore 66 coming in the extension of an inlet bore 68 of the receiving part (lid 50) of the bottle in a first alignment direction D1 (FIG. 4). Correspondingly, the second flange 20 comprises an inlet bore 70 proper to come in the extension of an outlet bore 72 of the receiving part (lid 50) of the bottle in a second alignment direction D2 (FIG. 4 ).

L'alésage d'entrée 68 traverse l'épaisseur de la partie réceptrice 50 et débouche à l'intérieur de la bouteille en amont de la cartouche 59. L'alésage de sortie 72 de la partie réceptrice 50 débouche dans un alésage radial 74 qui communique avec l'extrémité supérieure 64 du tube 56.The inlet bore 68 passes through the thickness of the receiving portion 50 and opens into the bottle upstream of the cartridge 59. The outlet bore 72 of the receiving portion 50 opens into a radial bore 74 which communicates with the upper end 64 of the tube 56.

L'alésage d'entrée 68 et l'alésage de sortie 72 de la partie réceptrice sont parallèles entre eux et à l'axe longitudinal XX de la bouteille 16. Les alésages 68 et 72 sont disposés dans une position angulaire choisie par rapport à l'axe longitudinal XX de la bouteille 16. Ceci permet de donner une orientation angulaire déterminée aux corps 12 et 14 par rapport à la bouteille 16 en fonction des conditions d'implantation du condenseur, par exemple dans le compartiment moteur d'un véhicule déterminé. Dans l'exemple de réalisation représenté, cette position angulaire est de sensiblement 180°, les alésages 68 et 72 étant disposés symétriquement de part et d'autre de l'axe longitudinal .The inlet bore 68 and the outlet bore 72 of the receiving portion are parallel to each other and to the axis longitudinal XX of the bottle 16. The bores 68 and 72 are arranged in a selected angular position relative to the longitudinal axis XX of the bottle 16. This allows to give a determined angular orientation to the bodies 12 and 14 with respect to the bottle 16 depending on the installation conditions of the condenser, for example in the engine compartment of a specific vehicle. In the exemplary embodiment shown, this angular position is substantially 180 °, the bores 68 and 72 being disposed symmetrically on either side of the longitudinal axis.

Comme on peut le voir sur la figure 4, l'alésage de sortie 66 de la première bride 18 se raccorde sensiblement à angle droit avec un alésage intermédiaire 76 débouchant dans le premier bloc 12. De plus, l'alésage d'entrée 70 de la deuxième bride 20 se raccorde sensiblement a angle droit avec un alésage intermédiaire 78 débouchant dans le deuxième bloc.As can be seen in FIG. 4, the outlet bore 66 of the first flange 18 is connected substantially at right angles to an intermediate bore 76 opening into the first block 12. In addition, the inlet bore 70 of the second flange 20 is connected substantially at right angles to an intermediate bore 78 opening into the second block.

II en résulte que le fluide frigorigène issu du premier bloc 12 pénètre dans la bouteille en passant successivement par l'alésage intermédiaire 76 et l'alésage de sortie 66 de la première bride puis par l'alésage d'entrée 68 de la partie réceptrice 50, pour être ensuite filtré et desséché en traversant la cartouche 59. Le fluide frigorigène remonte par le tube 56 pour traverser successivement l'alésage radial 74 et l'alésage de sortie 72 de la partie réceptrice puis l'alésage d'entrée 70 et l'alésage intermédiaire 78 de la deuxième bride 20 pour déboucher dans le deuxième bloc 14.As a result, the refrigerant from the first block 12 enters the bottle passing successively through the intermediate bore 76 and the outlet bore 66 of the first flange and then through the inlet bore 68 of the receiving portion 50 , to then be filtered and dried through the cartridge 59. The refrigerant rises through the tube 56 to successively pass through the radial bore 74 and the outlet bore 72 of the receiving portion and the inlet bore 70 and the intermediate bore 78 of the second flange 20 to open into the second block 14.

Pour assurer l 'étanchéité, on prévoit un premier raccord étanche entre la bride 18 et le couvercle 50 et un deuxième raccord étanche entre le couvercle 50 et la bride 20. Comme on le voit sur la coupe de la figure 4, le premier raccord étanche comprend une première tubulure 80 propre à être introduite dans l'alésage de sortie 66 de la première bride et dans l'alésage d'entrée 68 de la partie réceptrice avec interposition d'au moins un joint torique, dans l'exemple deux joints toriques 82. De même, le deuxième raccord étanche comprend une deuxième tubulure 84 propre à être introduite dans l'alésage d'entrée 70 de la deuxième bride et dans l'alésage de sortie 72 de la partie réceptrice avec interposition d'au moins un joint torique, ici deux joints toriques 86.For sealing, a first sealing connection is provided between the flange 18 and the cover 50 and a second sealing connection between the cover 50 and the flange 20. As seen in the section of FIG. 4, the first sealing connection comprises a first tube 80 adapted to be introduced into the outlet bore 66 of the first flange and into the inlet bore 68 of the receiving part with interposition of at least one O-ring, in the example two O-rings 82. Similarly, the second seal comprises a second manifold 84 adapted to be introduced into the inlet bore 70 of the second flange and into the outlet bore 72 of the receiving part with interposition of at least one O-ring, here two O-rings 86.

Les brides 18 et 20 sont propres à être fixées chacune sur la partie réceptrice 50 de la bouteille au moyen d'une vis 88, respectivement 90, qui à chaque fois traverse la bride et s'engage par vissage dans la partie réceptrice (voir figures 1, 5 et 6) . La bouteille 16 forme ainsi support pour les blocs 12 et 14 d'échange de chaleur qui peuvent être fixés avec une orientation mutuelle déterminée en fonction de la position angulaire respective des alésages 68 et 72.The flanges 18 and 20 are adapted to be each fixed to the receiving part 50 of the bottle by means of a screw 88, respectively 90, which each time passes through the flange and is screwed into the receiving part (see FIGS. 1, 5 and 6). The bottle 16 thus forms a support for the heat exchange blocks 12 and 14 which can be fixed with a mutual orientation determined according to the respective angular position of the bores 68 and 72.

Il est donc possible de concevoir des parties réceptrices 50 en fonction de l'application souhaitée pour permettre d'implanter les blocs 12 et 14 avec des orientations particulières par rapport à la partie réceptrice 50 suivant le type de véhicule auquel le condenseur est destiné.It is therefore possible to design receiving portions 50 according to the desired application to allow the blocks 12 and 14 to be implanted with particular orientations with respect to the receiving part 50 according to the type of vehicle for which the condenser is intended.

Comme la bouteille forme en même temps support, elle peut elle-même être munie de moyens d'interface ou de fixation (non représentés) pour la fixation sur la structure du véhicule auquel est destiné le condenseur.As the bottle forms at the same time support, it can itself be provided with interface means or attachment (not shown) for attachment to the structure of the vehicle to which the condenser is intended.

On comprendra que la bouteille peut être assemblée et pré- équipée avant d'être installée et fixée entre les deux blocs d'échange de chaleur, ce qui simplifie grandement les opérations de montage et d'assemblage, mais aussi les opérations de maintenance.It will be understood that the bottle can be assembled and pre-equipped before being installed and fixed between the two heat exchange blocks, which greatly simplifies the assembly and assembly operations, but also maintenance operations.

Par ailleurs, du fait que les blocs 12 et 14 et la bouteille 16 sont démontables les uns par rapport aux autres, il est possible de remplacer l'un de ces trois éléments en cas de défaillance.Moreover, because the blocks 12 and 14 and the bottle 16 are removable relative to each other, it is possible to replace one of these three elements in case of failure.

L'invention n'est pas limitée à la forme de réalisation décrite précédemment à titre d'exemple et s'étend à d'autres variantes.The invention is not limited to the embodiment described above by way of example and extends to other variants.

Ainsi, les blocs respectifs 12 et 14 du condenseur pourraient être réalisés suivant une autre technique que celle de la technique à plaques empilées.Thus, the respective blocks 12 and 14 of the condenser could be made using a technique other than that of the stacked plate technique.

L'invention trouve une application préférentielle aux circuits de climatisation des véhicules automobiles. The invention finds a preferential application to the air conditioning circuits of motor vehicles.
