[0026] Dans la présente description, on peut indexer certains éléments ou paramètres, comme par exemple premier élément ou deuxième élément ainsi que premier paramètre et second paramètre ou encore premier critère et deuxième critère, etc. Dans ce cas, il s’agit d’un simple indexage pour différencier et dénommer des éléments ou paramètres ou critères proches, mais non identiques. Cette indexation n’implique pas une priorité d’un élément, paramètre ou critère par rapport à un autre et on peut aisément interchanger de telles dénominations sans sortir du cadre de la présente description. Cette indexation n’implique pas non plus un ordre dans le temps par exemple pour apprécier tel ou tel critère. [0026] In the present description, certain elements or parameters can be indexed, such as for example first element or second element as well as first parameter and second parameter or even first criterion and second criterion, etc. In this case, it is a simple indexing to differentiate and name elements or parameters or criteria that are close, but not identical. This indexing does not imply a priority of one element, parameter or criterion in relation to another and such denominations can easily be interchanged without departing from the scope of the present description. This indexing does not imply an order in time either, for example to assess this or that criterion.
[0027] Dans la présente description, on entend par « placé en amont » qu’un élément est placé avant un autre par rapport au sens de circulation d'un fluide. A contrario, on entend par « placé en aval » qu’un élément est placé après un autre par rapport au sens de circulation du fluide. [0027] In the present description, the term “placed upstream” means that one element is placed before another with respect to the direction of circulation of a fluid. Conversely, by “placed downstream” we mean that one element is placed after another in relation to the direction of circulation of the fluid.
[0028] Sur les figures 1 à 8 est représenté un trièdre XYZ de direction. L’axe X correspond à un axe dit longitudinal. L’axe Y correspond à un axe dit transversal. L’axe Z correspond quant à lui à un axe dit vertical. [0028] Figures 1 to 8 show an XYZ direction trihedron. The X axis corresponds to a so-called longitudinal axis. The Y axis corresponds to a so-called transverse axis. The Z axis corresponds to a so-called vertical axis.
[0029] Les figures 1 et 2 montrent un bloc hydraulique 1 pour fluide réfrigérant d’un circuit de gestion thermique de véhicule automobile. Ce bloc hydraulique peut notamment être réalisé en métal usiné, par exemple en aluminium ou alliage d’aluminium. [0029] Figures 1 and 2 show a hydraulic block 1 for refrigerant fluid of a thermal management circuit of a motor vehicle. This hydraulic block can in particular be made of machined metal, for example aluminum or aluminum alloy.
[0030] Ce bloc hydraulique 1 a une forme parallélépipédique et comporte plus particulièrement une première face 11 dite arrière, visible plus en détail sur la figure 2. Cette face arrière 11 s’étend plus particulièrement dans un plan parallèle à l’axe transversale Y et à l’axe verticale Z. Cette face arrière 11 peut également être plane afin qu’un ou plusieurs éléments du circuit de gestion thermique puissent venir s’accoler à cette dernière. This hydraulic block 1 has a parallelepiped shape and more particularly comprises a first so-called rear face 11, visible in more detail in Figure 2. This rear face 11 extends more particularly in a plane parallel to the transverse axis Y and to the vertical axis Z. This rear face 11 can also be flat so that one or more elements of the thermal management circuit can be attached to the latter.
[0031] Le bloc hydraulique 1 comporte en outre une deuxième face 12 dite avant, opposée à la face arrière 11, visible plus en détail sur la figure 1. Cette face avant 12 peut notamment être parallèle à la face arrière 11 et ainsi également s’étendre dans un plan parallèle à l’axe transversale Y et à l’axe verticale Z. Cette face avant 12 peut également être plane afin qu’un ou plusieurs éléments du circuit de gestion thermique puissent venir s’accoler à cette dernière. [0031] The hydraulic block 1 further comprises a second so-called front face 12, opposite the rear face 11, visible in more detail in Figure 1. This front face 12 can in particular be parallel to the rear face 11 and thus also s extend in a plane parallel to the transverse axis Y and to the vertical axis Z. This front face 12 can also be flat so that one or more elements of the thermal management circuit can be attached to the latter.
[0032] Le bloc hydraulique 1 comporte également une troisième face 13 dite supérieure faisant la liaison entre une arrête de la face avant 12 et un côté de la face arrière 11. Cette face supérieure 13 peut notamment être perpendiculaire aux faces arrière 11 et avant 12. Cette face supérieure peut ainsi s’étendre dans un plan parallèle à l’axe transversale Y et à l’axe longitudinal X. Cette face supérieur 13 peut également comporter une ou plusieurs surfaces planes afin qu’un ou plusieurs éléments du circuit de gestion thermique puissent venir s’accoler à cette dernière. The hydraulic block 1 also includes a third so-called upper face 13 making the connection between an edge of the front face 12 and one side of the rear face 11. This upper face 13 can in particular be perpendicular to the rear faces 11 and front 12 This upper face can thus extend in a plane parallel to the transverse axis Y and to the longitudinal axis X. This upper face 13 can also include one or more flat surfaces so that one or more elements of the management circuit thermal can be attached to the latter.
[0033] Le bloc hydraulique 1 comporte une quatrième face 14 dite inférieure, opposée à la face supérieure 13. A l’instar de la face supérieure 13, cette face inférieure 14 fait la liaison entre une arrête de la face avant 12 et un côté de la face arrière 11. [0033] The hydraulic block 1 has a fourth face 14 called the lower face, opposite the upper face 13. Like the upper face 13, this lower face 14 makes the connection between an edge of the front face 12 and a side of the rear face 11.
[0034] Enfin, le bloc hydraulique 1 comporte une cinquième 15 et une sixième 16 face dites latérales, reliant la face avant 12 à la face arrière 11 d’une part et reliant la face inférieure 14 à la face supérieure 13 d’autre part. Au moins une de ses faces latérales 15, 16 peut être perpendiculaire aux faces arrière 11 et avant 12 ainsi que perpendiculaire à la face supérieure 13. Dans l’exemple illustré aux figures 1 à 8, il s’agit de la face latérale 15. Cette face latérale 15 peut également être plane afin qu’un ou plusieurs éléments du circuit de gestion thermique puissent venir s’accoler à cette dernière. [0034] Finally, the hydraulic block 1 comprises a fifth 15 and a sixth 16 face called lateral, connecting the front face 12 to the rear face 11 on the one hand and connecting the lower face 14 to the upper face 13 on the other hand. At least one of its side faces 15, 16 can be perpendicular to the rear faces 11 and front 12 as well as perpendicular to the upper face 13. In the example illustrated in Figures 1 to 8, this is the side face 15. This side face 15 can also be flat so that one or more elements of the thermal management circuit can be attached to the latter.
[0035] Le bloc hydraulique 1 comporte en outre un premier logement 21, configuré pour recevoir un élément d’une vanne trois-voies 40 (visible sur la figure 3), d’un premier chemin de circulation A du fluide réfrigérant au sein du bloc hydraulique 1. The hydraulic block 1 further comprises a first housing 21, configured to receive an element of a three-way valve 40 (visible in Figure 3), of a first circulation path A of the refrigerant fluid within the hydraulic block 1.
[0036] Ce premier chemin de circulation A comporte une première sortie Al de fluide réfrigérant disposée sur la face arrière 11 du bloc hydraulique 1 ainsi qu’une deuxième sortie A2 de fluide réfrigérant. Comme illustré sur les figures 1 à 8, la deuxième sortie A2 de fluide réfrigérant du premier chemin de circulation A peut notamment être disposée sur une face latérale 15, 16 du bloc hydraulique 1, ici la face latérale 15 plane. Il n’est néanmoins pas exclu que cette deuxième sortie A2 de fluide réfrigérant du premier chemin de circulation A soit disposée sur une autre face du bloc hydraulique 1. This first circulation path A comprises a first refrigerant fluid outlet Al arranged on the rear face 11 of the hydraulic block 1 as well as a second refrigerant fluid outlet A2. As illustrated in Figures 1 to 8, the second refrigerant fluid outlet A2 of the first circulation path A can in particular be arranged on a side face 15, 16 of the hydraulic block 1, here the side face 15 is flat. It is nevertheless not excluded that this second refrigerant fluid outlet A2 of the first circulation path A is arranged on another face of the hydraulic block 1.
[0037] Le premier chemin de circulation A comporte également une entrée A3 de fluide réfrigérant disposée sur une face distincte de la face arrière 11. Comme illustré sur les figures 1 à 8, cette entrée A3 de fluide réfrigérant du premier chemin de circulation A peut plus particulièrement est disposée sur la face avant 12 du bloc hydraulique 1. H n’est néanmoins pas exclu que cette entrée A3 de fluide réfrigérant du premier chemin de circulation A soit disposée sur une autre face du bloc hydraulique 1. [0037] The first circulation path A also includes a refrigerant fluid inlet A3 arranged on a separate face from the rear face 11. As illustrated in Figures 1 to 8, this refrigerant fluid inlet A3 of the first circulation path A can more particularly is arranged on the front face 12 of the hydraulic block 1. It is nevertheless not excluded that this refrigerant fluid inlet A3 of the first circulation path A is arranged on another face of the hydraulic block 1.
[0038] Comme illustré aux figures 1 à 8, le premier logement 21 configuré pour recevoir une vanne trois-voies 40 peut être un orifice réalisé sur une des faces supérieure 13 ou inférieure 14. Dans l’exemple illustré, il s’agit de la face supérieure 13. Cet orifice 21 est configuré pour recevoir un élément de redirection de la vanne trois-voies 40. Des conduites A10, A20, A30 du premier chemin de circulation A sont ménagées dans le bloc hydraulique 1 et convergent dans cet orifice 21. Ces conduites A10, A20, A30 sont reliées respectivement à l’entrée A3 de fluide réfrigérant, à la première sortie Al et à la deuxième sortie A2 de fluide réfrigérant du premier chemin de circulation A. [0038] As illustrated in Figures 1 to 8, the first housing 21 configured to receive a three-way valve 40 can be an orifice made on one of the upper faces 13 or lower 14. In the example illustrated, this is the upper face 13. This orifice 21 is configured to receive a redirection element of the three-way valve 40. Pipes A10, A20, A30 of the first circulation path A are provided in the hydraulic block 1 and converge in this orifice 21 These pipes A10, A20, A30 are connected respectively to the refrigerant fluid inlet A3, to the first outlet Al and to the second refrigerant fluid outlet A2 of the first circulation path A.
[0039] Une première conduite A 10, visible aux figures 4 à 6, relie la première sortie Al au premier logement 21. Une deuxième conduite A20, visible aux figures 4 à 6, relie la deuxième sortie A2 au premier logement 21. Et enfin, une troisième conduite A30, visible aux figures 5 et 6, relie l’entrée A3 au premier logement 21. [0040] Le bloc hydraulique 1 peut également comporter un premier orifice 51 configuré pour recevoir un premier capteur Cl (visible figure 3), par exemple un capteur de température et/ou de pression. Ce premier orifice 51 débouche dans la conduite A30 reliant l’entrée A3 de fluide réfrigérant du premier chemin de circulation A au premier logement 21. Ce premier orifice 51 peut notamment être réalisé sur n’importe laquelle des faces du bloc hydraulique 1, plus particulièrement une des faces la plus proche de la conduite A30, ici la face latérale 15, comme illustré aux figures 1 à 4. [0039] A first pipe A 10, visible in Figures 4 to 6, connects the first outlet Al to the first housing 21. A second pipe A20, visible in Figures 4 to 6, connects the second outlet A2 to the first housing 21. And finally , a third pipe A30, visible in Figures 5 and 6, connects the inlet A3 to the first housing 21. The hydraulic block 1 can also include a first orifice 51 configured to receive a first sensor Cl (visible in Figure 3), for example a temperature and/or pressure sensor. This first orifice 51 opens into the pipe A30 connecting the refrigerant fluid inlet A3 of the first circulation path A to the first housing 21. This first orifice 51 can in particular be made on any of the faces of the hydraulic block 1, more particularly one of the faces closest to pipe A30, here the side face 15, as illustrated in Figures 1 to 4.
[0041] La face portant le premier logement 21, ici la face supérieure 13, peut notamment comporter des orifices de fixation 63 afin de permettre la fixation au moyen de vis ou boulons de la vanne trois-voies 40. [0041] The face carrying the first housing 21, here the upper face 13, may in particular include fixing holes 63 in order to allow the three-way valve 40 to be fixed by means of screws or bolts.
[0042] Le bloc hydraulique comporte également un deuxième logement 22 configuré pour recevoir un élément d’une vanne d’expansion 41 d’un deuxième chemin de circulation B du fluide réfrigérant au sein du bloc hydraulique 1. Dans l’exemple illustré, il s’agit de la face supérieure 13. Ce deuxième chemin de circulation B comporte une entrée B 1 de fluide réfrigérant disposée sur la face arrière 11 du bloc hydraulique et une sortie B2 de fluide réfrigérant disposée sur une face distincte de la face arrière 11. Plus particulièrement, cette sortie B2 de fluide réfrigérant du deuxième chemin de circulation B peut être disposée sur la face avant 12 du bloc hydraulique 1. Il n’est néanmoins pas exclu que cette sortie B2 de fluide réfrigérant du deuxième chemin de circulation B soit disposée sur une autre face du bloc hydraulique. [0042] The hydraulic block also includes a second housing 22 configured to receive an element of an expansion valve 41 of a second circulation path B of the refrigerant fluid within the hydraulic block 1. In the example illustrated, it this is the upper face 13. This second circulation path B comprises an inlet B 1 of refrigerant fluid disposed on the rear face 11 of the hydraulic block and an outlet B2 of refrigerant fluid disposed on a separate face of the rear face 11. More particularly, this outlet B2 of refrigerant fluid from the second circulation path B can be arranged on the front face 12 of the hydraulic block 1. It is nevertheless not excluded that this outlet B2 of refrigerant fluid from the second circulation path B is arranged on another face of the hydraulic block.
[0043] De préférence et comme illustré aux figures 1 à 3, la sortie B2 de fluide réfrigérant du deuxième chemin de circulation B et l’entrée A3 de fluide réfrigérant du premier chemin de circulation A sont réalisées sur une même face du bloc hydraulique 1. [0043] Preferably and as illustrated in Figures 1 to 3, the refrigerant fluid outlet B2 of the second circulation path B and the refrigerant fluid inlet A3 of the first circulation path A are produced on the same face of the hydraulic block 1 .
[0044] Selon un premier mode de réalisation illustré aux figures 1 à 6, le deuxième logement 22 configuré pour recevoir une vanne d’expansion 41 est un orifice réalisé sur une des faces supérieure 13 ou inférieure 14. Cet orifice 22 est configuré pour recevoir un élément de détente de la vanne d’expansion 4L Des conduites B 10 et B20 du deuxième chemin de circulation B sont ménagées dans le bloc hydraulique 1 et convergent vers cet orifice 22. Les conduites B 10 et B20 sont reliées respectivement à l’entrée B1 et à la sortie B2 de fluide réfrigérant du deuxième chemin de circulation B. [0044] According to a first embodiment illustrated in Figures 1 to 6, the second housing 22 configured to receive an expansion valve 41 is an orifice made on one of the upper faces 13 or lower 14. This orifice 22 is configured to receive a relaxation element of the expansion valve 4L Pipes B 10 and B20 of the second circulation path B are provided in the hydraulic block 1 and converge towards this orifice 22. Pipes B 10 and B20 are connected respectively to the inlet B1 and at the refrigerant outlet B2 of the second circulation path B.
[0045] Une première conduite B 10, visible aux figures 4 et 6, relie l’entrée B 1 de fluide réfrigérant du deuxième chemin de circulation B au deuxième logement 22. Une deuxième conduite B20, visible aux figures 4 et 5, relie la sortie B2 de fluide réfrigérant du deuxième chemin de circulation B au deuxième logement 22. [0045] A first pipe B 10, visible in Figures 4 and 6, connects the refrigerant fluid inlet B 1 of the second circulation path B to the second housing 22. A second pipe B20, visible in Figures 4 and 5, connects the outlet B2 of refrigerant fluid from the second circulation path B to the second housing 22.
[0046] La face portant le deuxième logement 22 sous forme d’un orifice, ici la face su- périeure 13, peut notamment comporter des orifices de fixation 63’ afin de permettre la fixation au moyen de vis ou boulons de la vanne d’expansion 41. [0046] The face carrying the second housing 22 in the form of an orifice, here the upper face perieur 13, may in particular include fixing holes 63' in order to allow fixing by means of screws or bolts of the expansion valve 41.
[0047] Selon un deuxième mode de réalisation illustré aux figures 7 et 8, le deuxième logement 22 configuré pour recevoir une vanne d’expansion 41 est un renfoncement de la face arrière 11 vers la face avant 12 et ouvert sur une des faces supérieure 13 ou inférieure 14. Dans l’exemple illustré, ce renfoncement 22 est ouvert sur la face supérieure 13 du bloc hydraulique 1. Ce renfoncement 22 est configuré pour recevoir un élément de détente de la vanne d’expansion 41. Comme visible sur la figure 8, l’entrée B1 de fluide réfrigérant du deuxième chemin de circulation B débouche dans le renfoncement 22 et est destinée à être connectée fluidiquement à Télément de détente de la vanne d’expansion 41. According to a second embodiment illustrated in Figures 7 and 8, the second housing 22 configured to receive an expansion valve 41 is a recess from the rear face 11 towards the front face 12 and open on one of the upper faces 13 or lower 14. In the example illustrated, this recess 22 is open on the upper face 13 of the hydraulic block 1. This recess 22 is configured to receive a relaxation element of the expansion valve 41. As visible in Figure 8 , the refrigerant fluid inlet B1 of the second circulation path B opens into the recess 22 and is intended to be fluidly connected to the expansion element of the expansion valve 41.
[0048] De préférence, le premier 21 et le deuxième logement 22 sont réalisés sur une face identique du bloc hydraulique 1. Cela permet de réunir la vanne trois- voies 41 et la vanne d’expansion 42 sur une même face et ainsi facilite le montage et les éventuels remplacements. [0048] Preferably, the first 21 and the second housing 22 are made on an identical face of the hydraulic block 1. This makes it possible to bring together the three-way valve 41 and the expansion valve 42 on the same face and thus facilitates the assembly and possible replacements.
[0049] Comme illustré sur les figures 1 à 3, 5 et 7, le bloc hydraulique 1 peut comporter un deuxième orifice 52 configuré pour recevoir un deuxième capteur C2 (visible figure 3), par exemple un capteur de température et/ou de pression. Ce deuxième orifice 52 débouche dans le deuxième chemin de circulation B en aval du deuxième logement 22. Ce deuxième orifice 52 peut notamment être réalisé sur n’importe laquelle des faces du bloc hydraulique 1, plus particulièrement une des faces la plus proche du deuxième chemin de circulation B en aval du deuxième logement 22. Dans l’exemple illustré aux figures 1 à 3, 5 et 7, le deuxième orifice 52 est réalisé sur un plan incliné de la face supérieure. [0049] As illustrated in Figures 1 to 3, 5 and 7, the hydraulic block 1 can include a second orifice 52 configured to receive a second sensor C2 (visible in Figure 3), for example a temperature and/or pressure sensor . This second orifice 52 opens into the second circulation path B downstream of the second housing 22. This second orifice 52 can in particular be made on any of the faces of the hydraulic block 1, more particularly one of the faces closest to the second path circulation B downstream of the second housing 22. In the example illustrated in Figures 1 to 3, 5 and 7, the second orifice 52 is made on an inclined plane of the upper face.
[0050] Le bloc hydraulique 1 peut également comporter un orifice 60 configuré pour une insertion d’un outil de serrage, ledit orifice 60 s’étendant depuis la face avant 12 vers la face arrière 11 mais ne traversant pas complètement le bloc hydraulique 1. Cet orifice 60 est prolongé par un autre orifice 61 de diamètre inférieur qui débouche sur la face arrière 11. Cela permet ainsi d‘insérer une vis ou un boulon pour permettre la fixation d’un élément du circuit de gestion thermique venant s’accoler à la face arrière 11. The hydraulic block 1 may also include an orifice 60 configured for insertion of a tightening tool, said orifice 60 extending from the front face 12 towards the rear face 11 but not completely passing through the hydraulic block 1. This orifice 60 is extended by another orifice 61 of smaller diameter which opens onto the rear face 11. This thus makes it possible to insert a screw or a bolt to allow the fixing of an element of the thermal management circuit coming next to it. the rear face 11.
[0051] Toujours afin de permettre la fixation d’un élément du circuit de gestion thermique venant s’accoler à la face arrière 11, le bloc hydraulique 1 peut également comporter des lobbes 64 percés d’un orifice. Ces lobbes 64 dépassent par exemple d’une des faces latérales 15, inférieure 14 ou supérieure 13. L’orifice de ces lobbes 64 est perpendiculaire à la face arrière 11 afin de permettre l’insertion d’une vis ou d’un boulon pour permettre la fixation d’un élément du circuit de gestion thermique venant s’accoler à la face arrière 11. [0051] Still in order to allow the fixing of an element of the thermal management circuit coming next to the rear face 11, the hydraulic block 1 can also include lobes 64 pierced with an orifice. These lobes 64 protrude for example from one of the side faces 15, lower 14 or upper 13. The orifice of these lobes 64 is perpendicular to the rear face 11 in order to allow the insertion of a screw or a bolt for allow the fixing of an element of the thermal management circuit coming next to the rear face 11.
[0052] Ainsi, on voit bien que du fait de son architecture, le bloc hydraulique 1 permet de regrouper au sein d’une structure compacte des conduites A10, A20, A30, B10 et B20 pour deux chemins de circulation A et B distincts ainsi que des logements 21 et 22 pour d’autres éléments du circuit de gestion thermique tels qu’une vanne trois-voie 41 et une vanne d’expansion 42. Cela permet ainsi au circuit de gestion thermique d’être le plus compact possible. [0052] Thus, we can clearly see that due to its architecture, the hydraulic block 1 makes it possible to group together within a compact structure pipes A10, A20, A30, B10 and B20 for two separate circulation paths A and B as well as housings 21 and 22 for other elements of the thermal management circuit such as a three-way valve 41 and an expansion valve 42. This thus allows the thermal management circuit to be as compact as possible.
