Description Description
Titre de l’invention : Echangeur de chaleur à plaques comportant une multitude de compartiments d’échange de chaleur Title of the invention: Plate heat exchanger comprising a multitude of heat exchange compartments
[0001] La présente invention concerne un échangeur de chaleur à plaques comportant divers compartiments d’échange fluide. La présente invention concerne aussi une installation comprenant un circuit de fluide réfrigérant, au moins un circuit de circulation annexe d’un fluide caloporteur avec un tel échangeur de chaleur à plaques. The present invention relates to a plate heat exchanger comprising various fluid exchange compartments. The present invention also relates to an installation comprising a refrigerant fluid circuit, at least one auxiliary circulation circuit of a heat transfer fluid with such a plate heat exchanger.
[0002] Dans le domaine automobile, il est courant d’avoir à modifier une température d’un composant, tel qu’un moteur électrique, une batterie, un dispositif de stockage de calories et/ou de frigories ou analogue. A cet effet, le véhicule automobile est équipé d’une installation qui comprend un circuit de fluide ré frigérant à l’intérieur duquel circule un fluide réfrigérant et au moins un circuit de circulation annexe à l’intérieur duquel circule un fluide caloporteur. Le cir cuit de fluide réfrigérant comprend généralement un compresseur pour compri mer le fluide réfrigérant, un premier échangeur thermique appelé généralement condenseur pour refroidir le fluide réfrigérant à pression constante, un disposi tif de détente pour permettre une détente du fluide réfrigérant et un deuxième échangeur de chaleur dit refroidisseur, par exemple un échangeur de chaleur bifluide, généralement à plaques, agencé conjointement dans le circuit de fluide réfrigérant et dans le circuit de circulation annexe. Cet échangeur de chaleur bi fluide permet notamment les échanges d’énergie calorifique entre le fluide ré frigérant et le fluide caloporteur circulant dans le circuit de circulation annexe. Le circuit de circulation annexe comprend quant à lui généralement une pompe et un échangeur thermique apte à modifier une température d’un composant. [0002] In the automotive field, it is common to have to modify the temperature of a component, such as an electric motor, a battery, a calorie and/or cold storage device or the like. For this purpose, the motor vehicle is equipped with an installation which comprises a refrigerating fluid circuit inside which a refrigerating fluid circulates and at least one auxiliary circulation circuit inside which a heat transfer fluid circulates. The refrigerant circuit generally comprises a compressor to compress the refrigerant fluid, a first heat exchanger generally called a condenser to cool the refrigerant fluid at constant pressure, an expansion device to allow expansion of the refrigerant fluid and a second heat exchanger. heat said cooler, for example a two-fluid heat exchanger, generally plates, arranged jointly in the refrigerant circuit and in the auxiliary circulation circuit. This bi-fluid heat exchanger allows in particular the exchange of calorific energy between the refrigerating fluid and the heat transfer fluid circulating in the additional circulation circuit. The additional circulation circuit generally comprises a pump and a heat exchanger capable of modifying the temperature of a component.
[0003] L’échangeur de chaleur bifluide est un échangeur comprenant généralement des plaques empilées et jointes ensemble pour former des tubes délimitant des chambres de circulation du fluide réfrigérant ou du liquide caloporteur. La plaque comprend au moins quatre orifices pour permettre une première arrivée et une première sortie du fluide réfrigérant, et une deuxième arrivée et une deu xième sortie du liquide caloporteur à l’intérieur des chambres de circulation si tuées de part et d’autre d’une même plaque. [0003] The two-fluid heat exchanger is an exchanger generally comprising plates stacked and joined together to form tubes defining circulation chambers for the refrigerant fluid or the heat transfer liquid. The plate comprises at least four orifices to allow a first inlet and a first outlet of the refrigerant fluid, and a second inlet and a second outlet of the coolant liquid inside the circulation chambers if killed on either side of the same plate.
[0004] Il est également connu afin d’améliorer le coefficient de performance du circuit de fluide réfrigérant, de munir ce dernier d’un échangeur de chaleur interne configuré pour permettre les échanges d’énergie calorifique entre le fluide ré frigérant à haute pression en sortie du condenseur et le fluide réfrigérant à basse pression en sortie du refroidisseur. [0005] La multiplication de ces échangeurs de chaleur permet certes une meilleure ef ficacité cependant cela entraîne également des problèmes d’encombrement et de branchement des divers échangeurs de chaleur au sein du véhicule automo bile. [0004] In order to improve the coefficient of performance of the refrigerant circuit, it is also known to provide the latter with an internal heat exchanger configured to allow the exchange of heat energy between the high-pressure refrigerant fluid in outlet of the condenser and the low-pressure refrigerant fluid at the outlet of the chiller. [0005] The multiplication of these heat exchangers certainly allows better efficiency, however, this also leads to problems of space and connection of the various heat exchangers within the motor vehicle.
[0006] Un des buts de la présente invention est de remédier au moins partiellement aux inconvénients de l’art antérieur et de proposer un échangeur de chaleur compact et pouvant regrouper plusieurs fonctions afin d’occuper le moins de place possible et facilitant le branchement des échangeurs de chaleur. One of the aims of the present invention is to remedy at least partially the drawbacks of the prior art and to propose a compact heat exchanger which can combine several functions in order to occupy as little space as possible and to facilitate the connection of the heat exchangers.

[0042] Le troisième compartiment 30 d’échange de chaleur comporte un cinquième chemin de circulation 100e dans lequel est destiné à circuler un quatrième fluide caloporteur D entre une entrée 30D et une sortie 30D’ du quatrième fluide caloporteur D. Le troisième compartiment 30 comporte également un sixième chemin de circulation lOOf dans lequel est destiné à circuler le troisième fluide caloporteur C entre une entrée 30C et une sortie 30C’ dudit troisième fluide caloporteur C. La sortie 30C’ du troisième fluide caloporteur C du troisième compartiment 30 est plus particulièrement connectée à l’entrée 20C du troisième fluide caloporteur C du deuxième compartiment 20. Les cinquième 100e et sixième lOOf chemins de circulation sont empilés en alternance. De préférence, les sens de circulation dans le cinquième 100e et le sixième lOOf chemin de circulation sont à contre-courant afin d’améliorer les échanges de chaleur entre les deux fluides. The third heat exchange compartment 30 comprises a fifth circulation path 100e in which a fourth heat transfer fluid D is intended to circulate between an inlet 30D and an outlet 30D' of the fourth heat transfer fluid D. The third compartment 30 comprises also a sixth circulation path 100f in which the third heat transfer fluid C is intended to circulate between an inlet 30C and an outlet 30C' of said third heat transfer fluid C. The output 30C' of the third heat transfer fluid C of the third compartment 30 is more particularly connected at the inlet 20C of the third heat transfer fluid C of the second compartment 20. The fifth 100th and sixth 100th circulation paths are stacked alternately. Preferably, the directions of circulation in the fifth 100th and the sixth 100th circulation path are countercurrent in order to improve heat exchange between the two fluids.
[0043] Le troisième compartiment 30 est disposé côte à côte avec le premier compartiment 10. Cela permet, en combinaison avec le fait que les premier 10 et deuxième 20 compartiments soient empilés, d’avoir un échangeur de chaleur 1 compact et regroupant trois fonctions d’échanges de chaleur entre le premier A et le deuxième B fluide caloporteur dans le premier compartiment 10, entre le premier A et le troisième C fluide caloporteur dans le deuxième compartiment 20 et entre le troisième C et quatrième D fluide caloporteur dans le troisième compartiment 30.

La sortie 30C’ du troisième fluide caloporteur C du troisième compartiment 30 d’échange de chaleur est alors en vis-à-vis et connecté à l’entrée 20C du troisième fluide caloporteur C du deuxième compartiment 20 d’échange de chaleur. According to a first embodiment illustrated in Figures 1 to 4, the first 10 and the third 30 heat exchange compartment are arranged side by side and stacked on the same face of the second compartment 20 heat exchange. The output 30C' of the third heat transfer fluid C of the third heat exchange compartment 30 is then opposite and connected to the input 20C of the third heat transfer fluid C of the second heat exchange compartment 20.
[0045] Le premier compartiment 10 comporte ainsi une première plaque d’extrémité ou joue 101 disposée à une première extrémité de l’empilement de plaques 100 et comportant l’entrée 10A du premier fluide caloporteur A ainsi que l’entrée 10B et la sortie 1 OB’ du deuxième fluide caloporteur B. A une deuxième extrémité de l’empilement de plaques 100, le premier compartiment 10 comporte une deuxième plaque d’extrémité 102 faisant interface avec le deuxième compartiment 20. Cette deuxième plaque d’extrémité 102 laisse notamment passer le premier fluide caloporteur A dans le deuxième compartiment 20 mais bloque le deuxième fluide caloporteur B afin qu’il ne circule qu’au sein du premier compartiment 10. The first compartment 10 thus comprises a first end plate or flange 101 disposed at a first end of the stack of plates 100 and comprising the inlet 10A of the first heat transfer fluid A as well as the inlet 10B and the outlet 1 OB 'of the second heat transfer fluid B. At a second end of the stack of plates 100, the first compartment 10 comprises a second end plate 102 interfacing with the second compartment 20. This second end plate 102 leaves in particular pass the first heat transfer fluid A into the second compartment 20 but blocks the second heat transfer fluid B so that it only circulates within the first compartment 10.
[0046] Le troisième compartiment 30 comporte quant à lui une première plaque d’extrémité ou joue 101’ disposée à une première extrémité de l’empilement de plaques 100 et comportant l’entrée 30C du troisième fluide caloporteur C ainsi que l’entrée 30D et la sortie 30D’ du quatrième fluide caloporteur D. A une deuxième extrémité de l’empilement de plaques 100, le troisième compartiment 30 comporte également une deuxième plaque d’extrémité 102’ faisant interface avec le deuxième compartiment 20. Cette deuxième plaque d’extrémité 102e laisse notamment passer le troisième fluide caloporteur A dans le deuxième compartiment 20 mais bloque le quatrième fluide caloporteur D afin qu’il ne circule qu’au sein du troisième compartiment 30. The third compartment 30 for its part comprises a first end plate or flange 101′ disposed at a first end of the stack of plates 100 and comprising the inlet 30C of the third heat transfer fluid C as well as the inlet 30D and the outlet 30D' of the fourth heat transfer fluid D. At a second end of the stack of plates 100, the third compartment 30 also includes a second end plate 102' interfacing with the second compartment 20. This second plate end 102e in particular allows the third heat transfer fluid A to pass into the second compartment 20 but blocks the fourth heat transfer fluid D so that it only circulates within the third compartment 30.
[0047] Le deuxième compartiment 20 comporte quant à lui une plaque d’extrémité 103 disposée à l’extrémité de son empilement de plaques 100 opposée à l’extrémité en vis-à-vis des premier 10 et troisième 30 compartiments. Cette plaque d’extrémité 103 comporte notamment la sortie 20 A’ du premier fluide caloporteur A ainsi que la sortie 20C’ du troisième fluide caloporteur C. The second compartment 20 comprises an end plate 103 arranged at the end of its stack of plates 100 opposite the end facing the first 10 and third 30 compartments. This end plate 103 comprises in particular the outlet 20 A' of the first heat transfer fluid A as well as the outlet 20C' of the third heat transfer fluid C.
[0048] Dans l’exemple illustré aux figures 1 à 4, le deuxième compartiment 20 recouvre une surface au moins égale à l’addition de la surface des premier 10 et deuxième 20 compartiments de sorte que lesdits premier 10 et deuxième 20 compartiments puissent reposer entièrement sur le deuxième compartiment 20. Les chemins de circulation 100a, 100b, 100e et lOOf des premier 10 et deuxième 20 comportent chacun deux passes par plaque 100. Les chemins de circulation 100c, lOOd du deuxième compartiment 20 comportent quant à eux quatre passes par plaque 100. In the example illustrated in Figures 1 to 4, the second compartment 20 covers an area at least equal to the addition of the area of the first 10 and second 20 compartments so that said first 10 and second 20 compartments can rest entirely on the second compartment 20. The circulation paths 100a, 100b, 100e and 100f of the first 10 and second 20 each comprise two passes per plate 100. The circulation paths 100c, 100d of the second compartment 20 comprise four passes per plate 100.
[0049] Toujours selon l’exemple illustré aux figures 1 à 4, Les premier 10 et troisième 30 compartiments comportent le même nombre de plaques 100 de sorte que la hauteur des premier 10 et troisième 30 compartiments est identique. Il est cependant tout à fait possible d’imaginer une alternative dans laquelle es premier 10 et troisième 30 compartiments comportent un nombre de plaques 100 distincts afin de répondre à des contraintes et des demandes de puissance d’échange de chaleur desdits compartiments. Still according to the example illustrated in Figures 1 to 4, the first 10 and third 30 compartments comprise the same number of plates 100 so that the height of the first 10 and third 30 compartments is identical. However, it is quite possible to imagine an alternative in which the first 10 and third 30 compartments comprise a number of separate plates 100 in order to meet the constraints and heat exchange power demands of said compartments.
[0050] Selon une première variante du premier mode de réalisation visible sur les figures 3 et 4 en coupe, les premier 10 et troisième 30 compartiments sont réalisés à partir de deux empilements de plaques distincts. According to a first variant of the first embodiment visible in Figures 3 and 4 in section, the first 10 and third 30 compartments are made from two separate stacks of plates.
[0051] Selon une deuxième variante du premier mode de réalisation visible sur les figures 5 et 6 en coupe, les parties côtes à côtes des premier 10 et troisième 30 compartiments sont réalisées à partir d’un unique empilement de plaques 100 comportant à la fois les premier 100a, deuxième 100b, cinquième 100e et sixième lOOf chemins de circulation. According to a second variant of the first embodiment visible in FIGS. 5 and 6 in section, the side-by-side parts of the first 10 and third 30 compartments are made from a single stack of plates 100 comprising both the first 100a, second 100b, fifth 100th and sixth 100f circulation paths.
[0052] L’échangeur de chaleur 1 peut notamment être connecté au sein d’un dispositif de gestion thermique G illustré à la figure 7. Ce dispositif de gestion thermique G comporte une boucle de gestion thermique X au sein de laquelle est destiné à circuler un fluide réfrigérant. Cette boucle de gestion thermique X comporte dans le sens de circulation du fluide réfrigérant un compresseur 3, un condenseur 10, un dispositif de détente 4 et un refroidis seur 30. La boucle de gestion thermique X comporte également un échangeur de chaleur interne 20 connecté d’une part au fluide réfrigérant à haute pression (représenté en traits épais) en provenance du condenseur 10 et d’autre part au fluide réfrigérant à basse pression (représenté en traits fins) en provenance du refroidis seur 30. La boucle de gestion thermique X peut également comporter un dispositif de séparation de phase 5, par exemple un accumulateur disposé en amont du compresseur 3. Ce dispositif de séparation de phase 5 peut être disposé entre l’échangeur de chaleur interne 20 et le compresseur 3 comme illustré sur la figure 7. Dans une alternative non représentée le dispositif de séparation de phase 5 peut être disposé entre le refroidisseur 30 et l’échangeur de chaleur interne 20. Le fluide réfrigérant peut par exemple être du R744 ou encore du R1234yf. The heat exchanger 1 can in particular be connected within a thermal management device G illustrated in FIG. 7. This thermal management device G comprises a thermal management loop X within which is intended to circulate a refrigerant fluid. This thermal management loop X comprises, in the direction of circulation of the refrigerant fluid, a compressor 3, a condenser 10, an expansion device 4 and a cooler 30. The thermal management loop X also comprises an internal heat exchanger 20 connected to on the one hand to the high pressure refrigerant fluid (shown in thick lines) from the condenser 10 and on the other hand to the low pressure refrigerant fluid (shown in thin lines) from the cooler 30. The thermal management loop X may also comprise a phase separation device 5, for example an accumulator disposed upstream of the compressor 3. This phase separation device 5 may be disposed between the internal heat exchanger 20 and the compressor 3 as illustrated in FIG. In an alternative not shown, the phase separation device 5 can be arranged between the cooler 30 and the internal heat exchanger 20. ut for example be R744 or R1234yf.
[0053] Le condenseur 10 est également connecté à une première boucle de gestion thermique annexe Y dans laquelle est destiné à circuler un fluide caloporteur, par exemple de l’eau glycolée. Cette première boucle de gestion thermique annexe Y peut comporter en plus du condenseur 10 une pompe 6 ainsi qu’un radiateur 7, par exemple destiné à être traversé par un flux d’air externe afin de dissiper de la chaleur. The condenser 10 is also connected to a first annex thermal management loop Y in which a heat transfer fluid, for example glycol water, is intended to circulate. This first annex Y thermal management loop may comprise, in addition to the condenser 10, a pump 6 as well as a radiator 7, for example intended to be traversed by an external air flow in order to dissipate heat.
[0054] Le refroidisseur 30 est quant à lui connecté à une deuxième boucle de gestion thermique annexe Z dans laquelle est destiné à circuler un fluide caloporteur, par exemple de l’eau glycolée. Cette deuxième boucle de gestion thermique annexe Z peut comporter en plus du refroidisseur 30 une pompe 8 ainsi qu’un échangeur de chaleur 9, par exemple destiné à refroidir un élément du véhicule automobile comme par exemple les batteries. The cooler 30 is itself connected to a second management loop thermal appendix Z in which a heat transfer fluid, for example glycol water, is intended to circulate. This second annex thermal management loop Z may comprise, in addition to the cooler 30, a pump 8 as well as a heat exchanger 9, for example intended to cool an element of the motor vehicle such as the batteries.
[0055] Le premier compartiment 10 d’échange de chaleur 1 peut notamment correspondre au condenseur 10. Le premier chemin de circulation 100a est alors destiné à être traversé par le premier fluide caloporteur A étant le fluide réfrigérant à haute pression. Le deuxième chemin de circulation 100b est quant à lui destiné à être traversé par le deuxième fluide caloporteur B étant le fluide caloporteur circulant dans la première boucle de gestion thermique annexe Y. The first heat exchange compartment 10 may in particular correspond to the condenser 10. The first circulation path 100a is then intended to be traversed by the first heat transfer fluid A being the high pressure refrigerant fluid. The second circulation path 100b is intended to be crossed by the second heat transfer fluid B being the heat transfer fluid circulating in the first annex thermal management loop Y.
[0056] Le troisième compartiment d’échange de chaleur 30 peut correspondre au refroidisseur 30. Le cinquième chemin de circulation 100e est alors destiné à être traversé par le quatrième fluide caloporteur D étant le fluide caloporteur circulant dans la deuxième boucle de gestion thermique annexe Z. Le sixième chemin de circulation lOOf est quant à lui destiné à être traversé par le troisième fluide caloporteur C étant le fluide réfrigérant à basse pression. The third heat exchange compartment 30 may correspond to the cooler 30. The fifth circulation path 100th is then intended to be crossed by the fourth heat transfer fluid D being the heat transfer fluid circulating in the second annex thermal management loop Z The sixth circulation path 100f is for its part intended to be traversed by the third heat transfer fluid C being the low-pressure refrigerant fluid.
[0057] Le deuxième compartiment d’échange de chaleur 20 peut enfin correspondre à l’échangeur de chaleur interne 20. Le troisième chemin de circulation 100c est alors destiné à être traversé par le fluide réfrigérant à haute pression A ayant traversé le premier compartiment 10. Le quatrième chemin de circulation lOOd est quant à lui destiné à être traversé par le fluide réfrigérant à basse pression C ayant traversé le troisième compartiment d’échange de chaleur 30. The second heat exchange compartment 20 can finally correspond to the internal heat exchanger 20. The third circulation path 100c is then intended to be crossed by the high-pressure refrigerant A having passed through the first compartment 10 The fourth circulation path 100d is for its part intended to be traversed by the low-pressure refrigerant fluid C having passed through the third heat exchange compartment 30.
[0058] Le dispositif de gestion thermique X illustré à la figure 7 n’est qu’un exemple, il est tout à fait possible d’imaginer des architectures différentes, notamment par exemple dans lesquels les première Y et deuxième Z boucles de gestion thermiques annexes sont regroupées ensemble au sein d’une même boucle de gestion thermique annexe. Le deuxième B et le quatrième C fluide caloporteur seraient alors le même fluide caloporteur circulant dans cette boucle de gestion thermique annexe. The thermal management device X shown in Figure 7 is only an example, it is quite possible to imagine different architectures, in particular for example in which the first Y and second Z thermal management loops annexes are grouped together within the same annex thermal management loop. The second B and the fourth C heat transfer fluid would then be the same heat transfer fluid circulating in this additional thermal management loop.
[0059] Selon une alternative au premier mode de réalisation illustrée aux figures 8 et 9, le deuxième compartiment 20 peut comporter une deuxième entrée 20A2 du premier fluide réfrigérant A. Cette deuxième entrée 20A2 peut notamment rejoindre le premier fluide caloporteur A en provenance de l’entrée 20A afin de circuler dans les troisièmes chemins de circulation 100c. Cette deuxième entrée 20A2 peut par exemple permettre de connecter au deuxième compartiment 20 jouant un rôle d’échangeur de chaleur interne, un deuxième condenseur (non représenté) par exemple connecté en parallèle du premier compartiment 10 au sein de la boucle de gestion thermique X. According to an alternative to the first embodiment illustrated in Figures 8 and 9, the second compartment 20 may include a second inlet 20A2 of the first refrigerant fluid A. This second inlet 20A2 may in particular join the first heat transfer fluid A coming from the entry 20A in order to circulate in the third circulation paths 100c. This second input 20A2 can for example make it possible to connect to the second compartment 20 acting as an internal heat exchanger, a second condenser (not shown) for example connected in parallel to the first compartment 10 within the thermal management loop X.
[0060] Toujours selon l’alternative au premier mode de réalisation illustrée aux figures 8 et 9, le deuxième compartiment 20 peut comporter une deuxième entrée 20C2 du troisième fluide réfrigérant C. Cette deuxième entrée 20C2 peut notamment rejoindre le troisième fluide caloporteur C en provenance de l’entrée 20C afin de circuler dans les quatrièmes chemins de circulation 100b. Cette deuxième entrée 20C2 peut par exemple permettre de connecter au deuxième compartiment 20 jouant un rôle d’échangeur de chaleur interne, un deuxième refroidis seur (non représenté) par exemple connecté en parallèle du troisième compartiment 30 au sein de la boucle de gestion thermique X. Still according to the alternative to the first embodiment illustrated in Figures 8 and 9, the second compartment 20 may include a second entrance 20C2 of the third coolant C. This second inlet 20C2 can in particular join the third coolant C coming from the inlet 20C in order to circulate in the fourth circulation paths 100b. This second inlet 20C2 can for example make it possible to connect to the second compartment 20 acting as an internal heat exchanger, a second cooler (not shown) for example connected in parallel with the third compartment 30 within the thermal management loop X .
[0061] Selon un deuxième mode de réalisation illustré aux figures 10 à 12, le troisième compartiment 30 est disposé côte à côte de la superposition des premier 10 et deuxième 20 compartiments. Selon ce deuxième mode de réalisation, seul le premier compartiment 10 est disposé sur le deuxième compartiment 20. According to a second embodiment illustrated in Figures 10 to 12, the third compartment 30 is arranged side by side of the superposition of the first 10 and second 20 compartments. According to this second embodiment, only the first compartment 10 is arranged on the second compartment 20.
[0062] Dans ce deuxième mode de réalisation, la deuxième plaque d’extrémité 102’ du troisième compartiment 30 n’est ainsi pas côte à côte avec la deuxième plaque d’extrémité 102 du premier compartiment 10 comme dans le premier mode de réalisation, mais côte à côte avec la deuxième plaque d’extrémité 103 du deuxième compartiment 20. La sortie 30C’ du troisième fluide caloporteur C du troisième compartiment 30 est ainsi connectée à l’entrée 20C du troisième fluide caloporteur C du deuxième compartiment 20. Dans l’exemple illustré aux figures 11 et 12, cette connexion est réalisée par une plaque de liaison 105 délimitant ces conduites reliant la sortie 30C’ et l’entrée 20C et disposée en vis-à-vis de la plaque d’extrémité 103 du deuxième compartiment 20 et de la deuxième plaque d’extrémité 102’ du troisième compartiment 30. Toujours selon l’exemple illustré, l’échangeur de chaleur 1 peut également comporter un canal 20A’2 traversant le premier 10 et deuxième 20 compartiment de sorte à prolonger la sortie 20 A’ du premier fluide caloporteur A du deuxième compartiment 20 afin que le premier fluide caloporteur A ressorte au travers de la premier plaque d’extrémité 101 du premier compartiment 10. La sortie 20 A’ du deuxième compartiment 20 étant ici reliée à l’entrée de ce canal 20A’2 par une conduite ménagée dans la plaque de liaison 105. In this second embodiment, the second end plate 102' of the third compartment 30 is thus not side by side with the second end plate 102 of the first compartment 10 as in the first embodiment, but side by side with the second end plate 103 of the second compartment 20. The outlet 30C' of the third heat transfer fluid C of the third compartment 30 is thus connected to the inlet 20C of the third heat transfer fluid C of the second compartment 20. In the 'example illustrated in Figures 11 and 12, this connection is made by a connecting plate 105 delimiting these pipes connecting the outlet 30C' and the inlet 20C and arranged opposite the end plate 103 of the second compartment 20 and the second end plate 102' of the third compartment 30. Still according to the example illustrated, the heat exchanger 1 can also comprise a channel 20A'2 passing through the first 10 and second 20 compartment so as to pro along the outlet 20 A' of the first heat transfer fluid A of the second compartment 20 so that the first heat transfer fluid A emerges through the first end plate 101 of the first compartment 10. The outlet 20 A' of the second compartment 20 being here connected at the entrance to this channel 20A'2 by a conduit formed in the connecting plate 105.
[0063] Selon ce deuxième mode de réalisation et à l’instar du premier mode de réalisation, les premier 10 et troisième 30 compartiments peuvent être réalisés à partir de deux empilements de plaques 100 distincts. Selon une variante, les parties côtes à côtes des premier 10 et troisième 30 compartiments peuvent être réalisées à partir d’un unique empilement de plaques 100 comportant à la fois les premier 100a, deuxième 100b, cinquième 100e et sixième lOOf chemins de circulation. According to this second embodiment and like the first embodiment, the first 10 and third 30 compartments can be made from two separate stacks of plates 100. According to a variant, the side-by-side parts of the first 10 and third 30 compartments can be made from a single stack of plates 100 comprising both the first 100a, second 100b, fifth 100e and sixth 100f circulation paths.
[0064] De même, les deuxième 20 et troisième 30 compartiments peuvent être réalisés à partir de deux empilements de plaques distincts. Selon une autre variantes les parties côtes à côtes des deuxième 20 et troisième 30 compartiments peuvent être réalisées à partir d’un unique empilement de plaques 100 comportant à la fois les troisième 100c, quatrième lOOd, cinquième 100e et sixième lOOf chemins de circulation. Similarly, the second 20 and third 30 compartments can be made from two separate stacks of plates. According to another variant, the side-by-side parts of the second 20 and third 30 compartments can be made from a single stack of plates 100 comprising both the third 100c, fourth 100d, fifth 100th and sixth 100f traffic paths.
[0065] Selon l’exemple illustré aux figures 10 à 12, le troisième 30 compartiment comporte le même nombre de plaques 100 que les premier 10 et deuxième 20 compartiment réunis de sorte que la hauteur du troisième compartiment est identique à la hauteur de la superposition des premier 10 et deuxième 20 compartiments. Il est cependant tout à fait possible d’imaginer une alternative dans laquelle le troisième 30 compartiment comporte un nombre de plaques 100 distinct de la superposition des premier 10 et deuxième 20 compartiments afin de répondre à des contraintes et des demandes de puissance d’échange de chaleur desdits compartiments. According to the example illustrated in Figures 10 to 12, the third 30 compartment comprises the same number of plates 100 as the first 10 and second 20 compartment together so that the height of the third compartment is identical to the height of the superposition of the first 10 and second 20 compartments. It is however entirely possible to imagine an alternative in which the third 30 compartment comprises a number of plates 100 distinct from the superposition of the first 10 and second 20 compartments in order to meet the constraints and exchange power demands of heat from said compartments.
[0066] Selon un troisième mode de réalisation illustré aux figures 13 à 16, l’échangeur de chaleur 1 peut également comporter un quatrième compartiment 40 d’échange de chaleur. Ce quatrième compartiment 40 comporte notamment :According to a third embodiment illustrated in Figures 13 to 16, the heat exchanger 1 may also include a fourth compartment 40 for heat exchange. This fourth compartment 40 comprises in particular:
- un septième chemin de circulation lOOi dans lequel est destiné à circuler le quatrième fluide caloporteur D entre une entrée 40D et une sortie 40D’ du quatrième fluide caloporteur, et - a seventh circulation path lOOi in which the fourth heat transfer fluid D is intended to circulate between an inlet 40D and an outlet 40D' of the fourth heat transfer fluid, and
- un huitième chemin de circulation lOOj dans lequel est destiné à circuler le troisième fluide caloporteur C entre une entrée 40C et une sortie 40C’ du troisième fluide caloporteur C. - an eighth circulation path lOOj in which the third heat transfer fluid C is intended to circulate between an inlet 40C and an outlet 40C' of the third heat transfer fluid C.
[0067] Selon une première alternative du troisième mode de réalisation illustrée aux figures 13 à 16, la sortie 40C’ du troisième fluide caloporteur C du quatrième compartiment 30 peut être connectée à l’entrée 20C du troisième fluide caloporteur C du deuxième compartiment 20. Les septième lOOi et huitième lOOj chemins de circulation sont empilés en alternance. De préférence, le sens de circulation dans le septième lOOi et le huitième lOOj chemin de circulation sont à contre-courant afin d’améliorer les échanges de chaleur entre les deux fluides. Plus particulièrement, la sortie 40C’ du quatrième compartiment 40 et la sortie 30C’ du troisième compartiment 30 sont toutes deux connectées à l’entrée 20C du troisième fluide caloporteur C du deuxième compartiment 20. According to a first alternative of the third embodiment illustrated in Figures 13 to 16, the output 40C 'of the third heat transfer fluid C of the fourth compartment 30 can be connected to the input 20C of the third heat transfer fluid C of the second compartment 20. The seventh 100i and eighth 100j circulation paths are stacked alternately. Preferably, the direction of circulation in the seventh lOOi and the eighth lOOj circulation path are against the current in order to improve the heat exchanges between the two fluids. More particularly, the outlet 40C' of the fourth compartment 40 and the outlet 30C' of the third compartment 30 are both connected to the inlet 20C of the third heat transfer fluid C of the second compartment 20.
[0068] Selon une deuxième alternative du troisième mode de réalisation non représentée, la sortie 40C’ du troisième fluide caloporteur C du quatrième compartiment 30 peut être libre ou bien connectée directement à la sortie 20C’ du troisième fluide caloporteur C du deuxième compartiment 20. According to a second alternative of the third embodiment, not shown, the outlet 40C' of the third heat transfer fluid C of the fourth compartment 30 can be free or connected directly to the outlet 20C' of the third heat transfer fluid C of the second compartment 20.
[0069] Les figures 13 à 15 montrent une première variante de ce troisième mode de réalisation dans laquelle le troisième compartiment 30 est disposé côte à côte du premier compartiment 10 sur un premier côté et le quatrième compartiment 40 est disposé côte à côte du troisième compartiment 30 sur un deuxième côté du troisième compartiment 30 opposé à son premier côté. [0069] Figures 13 to 15 show a first variant of this third embodiment in which the third compartment 30 is arranged side by side of the first compartment 10 on a first side and the fourth compartment 40 is arranged side by side of the third compartment 30 on a second side of the third compartment 30 opposite its first side.
[0070] L’exemple des figures 13 à 15, reprend la caractéristique du deuxième mode de réalisation dans lequel le troisième compartiment 30 est disposé côte à côte de la superposition des premier 10 et deuxième 20 compartiments. Ainsi, dans cet exemple, seul le premier compartiment 10 est disposé sur le deuxième compartiment 20. Il est cependant tout à fait possible d’imaginer un mode de réalisation dans lequel à la fois le premier 10, le troisième 30 et le quatrième 40 compartiments sont disposés sur le deuxième compartiment 20. The example of Figures 13 to 15 repeats the characteristic of the second embodiment in which the third compartment 30 is arranged side by side of the superposition of the first 10 and second 20 compartments. So in this example, only the first compartment 10 is arranged on the second compartment 20. It is however quite possible to imagine an embodiment in which both the first 10, the third 30 and the fourth 40 compartments are arranged on the second compartment 20.
[0071] En revenant à l’exemple des figures 13 à 15, la sortie 40C’ du quatrième compartiment 40 et la sortie 30C’ du troisième compartiment 30 sont toutes deux connectées à l’entrée 20C du troisième fluide caloporteur C du deuxième compartiment 20 via la plaque de liaison 105. Returning to the example of Figures 13 to 15, the output 40C 'of the fourth compartment 40 and the output 30C' of the third compartment 30 are both connected to the input 20C of the third heat transfer fluid C of the second compartment 20 via connecting plate 105.
[0072] La figure 16 montre une deuxième variante du troisième mode de réalisation dans laquelle le troisième compartiment 30 et le quatrième compartiment 40 sont tous deux disposés côte à côte du premier compartiment 10 sur un premier côté. Le quatrième compartiment 40 est également disposé côte à côte du troisième compartiment 30 sur un deuxième côté du troisième compartiment 30 contigu avec son premier côté. De même que pour la première variante, l’exemple illustré à la figure 16 reprend la caractéristique du deuxième mode de réalisation dans lequel le troisième compartiment 30 est disposé côte à côte de la superposition des premier 10 et deuxième 20 compartiments. Ainsi, dans cet exemple, seul le premier compartiment 10 est disposé sur le deuxième compartiment 20. Il est cependant tout à fait possible d’imaginer un mode de réalisation dans lequel à la fois le premier 10, le troisième 30 et le quatrième 40 compartiments sont disposés sur le deuxième compartiment 20. [0072] Figure 16 shows a second variant of the third embodiment in which the third compartment 30 and the fourth compartment 40 are both arranged side by side of the first compartment 10 on a first side. The fourth compartment 40 is also arranged side by side of the third compartment 30 on a second side of the third compartment 30 contiguous with its first side. As with the first variant, the example illustrated in Figure 16 repeats the characteristic of the second embodiment in which the third compartment 30 is arranged side by side of the superposition of the first 10 and second 20 compartments. Thus, in this example, only the first compartment 10 is arranged on the second compartment 20. It is however quite possible to imagine an embodiment in which both the first 10, the third 30 and the fourth 40 compartments are arranged on the second compartment 20.
[0073] Ainsi, ont voir bien que l’échangeur de chaleur 1 de par sa division en différents compartiments 10, 20, 30 ainsi que les différentes connexions des chemins de circulations de fluide caloporteur, permet d’avoir un échangeur de chaleur compact et pouvant regrouper diverses fonctions telles qu’un condenseur, un refroidisseur et un échangeur de chaleur interne. Cela permet une meilleure compacité pour une meilleure intégration au sein d’un véhicule automobile. De plus la structure de l’échangeur de chaleur 1 permet également un montage plus aisé notamment au niveau des connexions avec un dispositif de gestion thermique comportant divers circuits de circulation du fait qu’il intègre en son sein déjà certaines connexions et ainsi réduit le nombre de connexions nécessaires. Thus, we can see that the heat exchanger 1 by its division into different compartments 10, 20, 30 as well as the different connections of the heat transfer fluid circulation paths, makes it possible to have a compact heat exchanger and which can combine various functions such as a condenser, a cooler and an internal heat exchanger. This allows better compactness for better integration within a motor vehicle. In addition, the structure of the heat exchanger 1 also allows easier assembly, in particular at the level of the connections with a thermal management device comprising various circulation circuits, because it already incorporates certain connections within it and thus reduces the number necessary connections.
