Description Title of the invention: Joining mechanism between a male-type pipe end and a female-type pipe end
[0001] The present invention relates to the field of leak-proof connection devices for sections of piping and more particularly to the field of connection devices involved in the circulation and / or distribution of heat transfer fluid for the thermal regulation of battery cells.
[0002] Maintaining the temperature of batteries typically involves heat exchange plates positioned in contact with the surface of the batteries to be heated or cooled. Each of these heat exchange plates has a hollow structure within which a heat transfer fluid circulates. The contact of such a plate with the surface of a battery optimizes heat exchange between the two surfaces. The heat transfer fluid moving within a heat exchange plate allows for the continuous transfer of heat to or from the battery. This circulation of the heat transfer fluid thus ensures optimal heat exchange between the battery and the heat exchange plate, with a continuous supply or removal of heat.
[0003] Inside the heat exchange plates, the heat transfer fluid moves between two ports, inlet and outlet, generally located at the periphery of the plates. In a known arrangement, these heat exchange plates are placed side-by-side in parallel planes, alternating with one or more battery cells. Each heat exchange plate is supplied with heat transfer fluid via sections of piping positioned at the inlet and outlet ports of each plate and oriented, for example, along an axis substantially perpendicular to the plane of the plates. These piping sections are then integrated into the heat exchange plates to create unit modules, each combining at least one heat exchange plate. with sections of duct for circulating heat transfer fluid to allow the construction of heat exchange systems that are easily adaptable to the number of battery cells present. In an optimized heat exchange system design, these modules may also include support elements incorporating housings for battery cells. Ultimately, the heat exchange system is achieved by juxtaposing several unit modules in an alternating arrangement of heat exchange plates and battery cells.During the installation and assembly of the units of such a heat exchange system, the different sections of piping respectively integrated into the heat exchange plates, or even into the battery cell support elements, are connected to each other in order to allow the creation of a heat transfer fluid distribution circuit.
[0004] In this type of construction, it remains imperative to ensure the perfect sealing of the volumes through which the heat transfer fluid passes. Indeed, any leak of heat transfer fluid near batteries could lead not only to a degradation in the operating performance of these batteries but also to damage to the motor powered by the energy supplied by them. Furthermore, batteries, which are generally associated with heat exchange systems, operate using rare earth elements and are prone to significant exothermic reactions upon contact with certain liquids, reinforcing the need for rigorous sealing of the heat transfer fluid distribution circuit, and in particular of the connections between the different sections of piping.
[0005] The present invention aims to overcome these drawbacks of the prior art by proposing a solution based on a sealing mechanism for the connection of the sections of piping for the circulation of heat transfer fluid which makes it possible, on the one hand, to limit the risk of loss of sealing and, on the other hand, to detect this possible loss of sealing without this loss of sealing impacting the operation of the system integrating this sealing mechanism, in particular when this system integrates battery cells.
[0006] The invention thus relates to a junction system for the circulation of a fluid between, on the one hand, an axial end of a male-type conduit and, on the other hand, an axial end of a female-type conduit, such that the system comprises: - a first connection interface formed by the outer surface of an axial end of a male-type conduit, - a second connection interface with a shape complementary to the first connection interface, this second connection interface being formed by the inner surface of an axial end of a female-type conduit, - an axial elastic intermediate junction device comprising at least one surface opposite the first connection interface and one surface opposite the second connection interface, to be arranged in compression between the two connection interfaces, characterized in that: - the surface of the second connection interface includes an external drainage port in communication with a drainage channel carried by the axial end of a female-type conduit, - the axial elastic intermediate junction device comprises on its surface opposite the second connection interface, at least two lips or series of lips respectively arranged in a plane orthogonal to the axis of the intermediate junction device and / or to the axis of the female type conduit end, the intermediate junction device being positioned in insertion into the female type conduit end so that each lip or series of lips of the intermediate junction device is arranged on either side of the external drainage orifice of the second connection interface.
[0007] The invention also relates to a module for a heat exchange assembly of at least one battery cell, comprising at least: - a heat exchange panel positioned against the supporting structure and comprising an internal volume for the circulation of a heat exchange fluid between at least one inlet and one outlet of the fluid, the inlet and outlet outlets being associated with an axial portion of respective conduit arranged along an axis substantially orthogonal to the plane of the heat exchange panel, - a support structure having a substantially planar arrangement of dimensions similar to the heat exchange panel and comprising at least one orifice forming a housing of complementary shape to the peripheral edge of at least one battery cell, at least one peripheral edge of the support structure carrying at least one axial portion of conduit arranged opposite and coaxially with the axial portion of conduit of an inlet or outlet orifice of the heat exchange panel, the axial portions of conduit arranged opposite each other having male / female type arrangements, characterized in that the axial portions of conduit arranged opposite each other are assembled by a joining system according to the invention.
[0008] The invention will be better understood from the following description, which relates to a preferred embodiment, given by way of non-limiting example, and explained with reference to the accompanying schematic drawings, in which: [Fig. 1] represents a schematic illustration in section view of a first example of an axial elastic intermediate junction device inserted at the level of a female-type conduit for a junction system according to the invention positioned at the level of an axial portion of a conduit of a fluid outlet orifice of a heat exchange panel, [Fig. 2] represents a schematic illustration according to a sectional view of a second example of an axial elastic intermediate junction device inserted at the level of a female-type conduit within a junction system according to the invention positioned at the level of an axial portion of a conduit of a fluid inlet orifice of heat exchange panels, [Fig. 3] represents a schematic illustration in three-quarter view of an example of a heat exchange panel incorporating axial portions of male and / or female type ducts for a module according to the invention, [Fig. 4] represents a schematic illustration of an example of an assembly of module elements for a heat exchanger assembly according to a view in section at the level of junction systems according to the invention, the plane of the section passing through the junction axis, [Fig. 5] represents a schematic illustration of an example of an assembly of module elements involving a first example of a ball joint mechanism in a set of heat exchangers according to a sectional view at the level of junction systems according to the invention, the plane of the section passing through the junction axis, [Fig. 6] represents a schematic illustration of an example of an assembly of module elements involving a second example of a ball joint mechanism in a set of heat exchangers according to a sectional view at the level of junction systems according to the invention, the plane of the section passing through the junction axis, [Fig. 7] represents a schematic illustration according to a sectional view of an example of a watertight joint at the level of a male type conduit welded at the level of an inlet port of a heat exchange panel within the framework of joint systems according to the invention.
[0009] The invention relates to a junction system 1 for the circulation of a fluid between, on the one hand, an axial end of a male-type conduit 2 and, on the other hand, an axial end of a female-type conduit 3, such that the system 1 comprises: - a first connection interface 21 formed by the outer surface of an axial end of a male-type conduit 2, - a second connection interface 31 of complementary shape to the first connection interface 21, this second connection interface 31 being formed by the inner surface of an axial end of a female-type conduit 3, - an axial elastic intermediate junction device 11 comprising at least one surface 112 opposite the first connection interface 21 and a surface 113 opposite the second connection interface 31, to be arranged in compression between the two connection interfaces 21, 31, characterized in that: - the surface of the second connection interface 31 includes an external drainage orifice 41 in communication with a drainage channel carried by the axial end of a female-type conduit 3, - the axial elastic intermediate junction device 11 comprises on its surface opposite the second connection interface 31, at least two lips or series of lips 51, 52 respectively arranged in a plane orthogonal to the axis of the intermediate junction device 11 and / or to the axis of the female type conduit end 31, the intermediate junction device 11 being positioned in insertion into the female type conduit end 31 so that each lip or series of lips 51, 52 of the intermediate junction device 11 is arranged on either side of the external drainage orifice 41 of the second connection interface 31.
[0010] The junction system 1 of the invention is thus constructed so as to integrate, between the end of a male type conduit 2 and the end of a female type conduit 3, a double external sealing line respectively made by the at least two lips or series of lips 51, 52 of the axial elastic intermediate junction device 11 positioned in insertion between the conduits, male 2 and female 3. Each of these at least two lips or series of lips 51, 52 makes a continuous annular relief on the whole of the periphery or circumference of the intermediate junction device 11, these reliefs being preferably arranged in respective planes in section perpendicular to the axis of the junction device 11.This double external sealing line carried by the surface of the junction device 11 opposite the second connection interface 31, i.e. the peripheral surface of the junction device 11 in contact with the inner surface of the female type conduit 3, cooperates with an external drainage orifice 41 positioned at the level of the second connection interface 31, i.e. carried by the inner surface of the female type conduit 3. This cooperation is arranged to allow, in the event of a leak between the junction device 11 and the female type conduit 3, at the level of the first external sealing line formed by the lip or series of lips 51 located closest to the end of the male type conduit 2 or at the deepest point of the female type conduit 3, on the one hand, a blocking of the leak by the second external sealing line formed by the lip or series of lips 52 located at a distance from the end of the male type conduit. 2 or as close as possible to the end of the female-type conduit 3 and, on the other hand, recovery of the flowing fluid at the external drain port 41 and its discharge through a drainage channel. The drainage channel may be associated with a fluid detector so that the identification of a heat transfer fluid circulating in this channel indicates the presence of a leak at the junction between the male-type conduits 2 and 3.
[0011] According to a preferred construction, the axial elastic intermediate junction device 11 has a substantially axial tubular shape arrangement configured to be positioned coaxially, on one side, with the axis of the end of the male-type conduit 2 and, on the other side, with the axis of the end of the female-type conduit 3. In a cross-sectional plane perpendicular to the tubular axis, the junction device 11 has inner and outer surfaces of shape and dimensions that are substantially complementary to the shapes and dimensions of the outer surface of the tubular end of the male-type conduit 2 and the inner surface of the tubular end of the female-type conduit 3. The junction device 11 is made of an elastic material that allows deformation while exhibiting compressive strength properties.For example, the elastic material is a rubber or equivalent material that also exhibits chemical resistance to the fluid intended to circulate at the junction involved in the connection between the male-type conduit 2 and the female-type conduit 3. Since the junction device 11 has elastic properties, it is preferred that, in a cross-sectional plane perpendicular to the tubular axis, the dimensions of the inner surface of the junction device 11 be slightly smaller than those of the outer surface of the tubular end of the male-type conduit 2. Similarly, in this same plane, it is preferred that the outer dimensions of the outer surface of the junction device 11 be slightly larger than those of the inner surface of the tubular end of the female-type conduit 3.Such dimensioning of the internal and external surfaces of the junction device 11 in relation to the male 2 and female 3 type conduits, between which the device 11 is positioned, makes it possible to guarantee a minimum compressive force of the respective surfaces of each of the conduits 2, 3 against the external and internal surfaces of the junction device 11 so that the possibility of the occurrence. of an opening between each of the conduits 2, 3 and the junction device 1 1 is reduced and the sealing of this junction is optimized.
[0012] According to an example relating to a variant of the construction of the junction system according to the invention, in cross-sectional planes parallel and orthogonal to the end axis of the female-type conduit 3, arranged on either side of the external drainage port 41, the surface of the second connection interface 31 has different dimensions such that, in a cross-sectional plane including the end axis of the female-type conduit 3, the surface of the second connection interface 31 has a shoulder 32. This shoulder 32 is preferably located on the inner surface of the female-type conduit 3 in the form of an annular arrangement. This shoulder 32 is capable of having a slope or inclination in a cross-sectional plane including the end axis of the female-type conduit 3.According to a particular, or even preferred, example of this construction variant, the shoulder 32 is made at the orifice at the end of the female-type conduit 3 so that the dimensions of the inner surface are larger near the end of the conduit 3 and smaller further away from the end of the conduit 3. Such a configuration of the shoulder 32 allows for a reduction or narrowing of the orifice of the female-type conduit 3 in the depth of the insertion of the connecting device 11 in this conduit 3. Thus, the compressive force exerted by the second connection interface 31 of the female-type conduit 3 against the connecting device 11 is greater at the depth of the conduit 3 than at its end.Also, the first external sealing line formed by the lip or series of lips 51 of the junction device 1 1 located deep within the female type conduit 3 supports a greater compressive force allowing to optimize the resistance of the junction device 11 to the pressure of the circulating fluid and therefore the sealing of the junction between the junction device 11 and the second connection interface 31 of the female type conduit 3.
[0013] According to an example relating to another construction variant of the junction system according to the invention, which can be combined with either of the variants detailed above, the elastic intermediate device Since the axial junction 11 is achieved by a tubular joint, the junction device 11 comprises: - at least one internal drainage orifice 42 formed by a hole passing through the thickness of the junction device 11 between the surfaces respectively positioned opposite the first connection interface 21 and the second connection interface 31 of the female type conduit 3, this internal drainage orifice 42 being positioned between the at least two lips or series of lips 51, 52 carried by the surface of the junction device 11 opposite the second connection interface 31 of the female type conduit 3, - at least two lips or series of lips 53, 54 carried by the surface of the junction device 11 opposite the first connection interface 21 of the male type conduit 2 and respectively arranged in a plane orthogonal to the axis of the junction device 11 and / or to the axis of the end of the male type conduit 2 positioned in insertion in the junction device 11 so that each lip or series of lips 53, 54 is arranged on either side of the internal drainage orifice 42. According to this construction variant, the junction system 1 of the invention also incorporates a double internal sealing line respectively formed by the at least two lips or series of lips 53, 54 of the axial elastic intermediate junction device 1 1 positioned in insertion between the conduits, male 2 and female 3. Each of these at least two lips or series of lips 53, 54 forms a continuous annular relief on the entire internal surface of the intermediate junction device 1 1, these reliefs being preferably arranged in respective section planes perpendicular to the axis of the junction device 1 1.This double internal sealing line carried by the surface of the junction device 11 opposite the first connection interface 21, i.e., the inner surface of the junction device 11 in contact with the outer surface of the male-type conduit 2, cooperates with an internal drainage orifice 42 carried by the junction device 11 such that this orifice passes through the thickness of the junction device 11. This cooperation between the double internal sealing line and the through-hole internal drainage orifice 42 carried by the junction device 11 is configured to allow, in the event of a leak between the device. junction 1 and the male type conduit 2, at the level of the first internal sealing line formed by the lip or series of lips 53 located as close as possible to the end of the male type conduit 2 or as close as possible to the end of the female type conduit 3, on the one hand, a blocking of the leak by the second internal sealing line made by the lip or series of lips 54 located at a distance from the end of the male type conduit 2 or as close as possible to the end of the female type conduit 3 and, on the other hand, a recovery of the flowing fluid at the level of the internal drainage orifice 42 and its evacuation by the external drainage orifice 41 and the drainage channel.Indeed, the external drainage orifice 41 being positioned between the at least two lips or series of lips 51, 52 carried by the surface of the junction device 11 opposite the second connection interface 31 of the female type conduit 3, the fluid flowing from the internal drainage orifice 42 is bounded between the two lips or series of lips 51, 52 and evacuated towards the external drainage orifice 41.
[0014] According to an example relating to another specific construction variant of the previously detailed junction system, the joint of the axial elastic intermediate junction device 11 comprises several internal drainage ports 42 arranged in the same plane orthogonal to the axis of the tubular joint. According to this construction variant, the junction device 11 comprises several drainage ports 42 arranged through its thickness so as to allow the evacuation of a fluid flowing between the junction device 11 and the male-type conduit 2 regardless of the spatial orientation of the junction system 1 of the invention.According to a particular embodiment of these drainage orifices 42, they are juxtaposed with an arrangement in the same plane in section perpendicular to the axis of the joining device 11 so as to present a configuration similar to a discontinuous annular groove which crosses the thickness of the joining device 11. In addition, each of these drainage orifices 42 is likely to have a circular or grooved shape, for example rectangular or oblong.
[0015] According to an example relating to another construction variant of the junction system according to the invention, which can be combined with some of the variants detailed above and which provides an alternative to the construction of an internal drainage orifice 42 passing through the thickness of the junction device 11, the intermediate axial elastic junction device 11 is made by at least two junction joints 11a, 11b such that: - the surface of each of the joining joints 11a, 11b opposite the second connection interface 31 has at least one of the at least two lips or at least one of the at least two sets of lips 51, 52, - the at least two connecting joints 11a, 11b are mounted spaced apart from each other so as to be separated by at least one internal drainage conduit 43 positioned between the at least two lips or series of lips 51, 52 carried by the connecting joints 11a, 11b opposite the second connection interface 31, - the surface of each of the junction joints 1 1 a, 1 1 b opposite the first connection interface 21 has at least one lip or at least a series of lips 53, 54, each of these lips or series of lips 53, 54 being arranged in a plane orthogonal to the axis of the joint and / or to the axis of the end of the male type conduit 2 positioned in insertion in the intermediate axial elastic junction device 1 1 so that at least one lip or series of lips 53, 54 is arranged on either side of the internal drainage conduit 43. According to this construction variant, the intermediate axial elastic junction device 11 is made in the form of at least two elements corresponding respectively to junction joints 11a, 11b positioned in insertion between the conduits, male 2 and female 3. These two junction joints 11a, 11b are positioned apart from each other between the two conduits, male 2 and female 3, so that the spacing between these two junction joints 11a, 11b, also partitioned between, on the one hand, the surface of the male conduit 2 forming the first connection interface 21 and, on the other hand, the surface of the female conduit 3 forming the second connection interface 31, creates an internal drainage conduit 43 of annular shape between the two conduits, male 2 and female 3.In addition to the at least two lips or at least two sets of lips 51, 52 positioned opposite the second connection interface 31 of the female type conduit 3, each of the at least two joining joints 11a, 11b has one or more lips forming at least two lips or sets of lips 53, 54 positioned opposite the. first connection interface 21 of the male type conduit 2 so as to achieve a double internal sealing line between the junction device 11 and the male type conduit 2. Preferably, each of these at least two lips or series of lips 53, 54 creates a continuous annular relief over the entire inner surface of each of the junction joints 11a, 11b. Preferably, these reliefs are arranged in respective section planes perpendicular to the axis of the junction device 11 or of each of the junction joints 11a, 11b. This double internal sealing line carried by the surface of each of the joints 11a, 11b opposite the first connection interface 21, i.e. the surface of the junction device 11 bearing against the outer surface of the male type conduit 2, cooperates with the internal drainage conduit 43 formed by the spacing between the two junction joints 11a, 11b.This cooperation between the double internal sealing line and the internal drainage conduit 43 of the junction device 11 is configured to allow, in the event of a leak between a first junction joint 11a and the male type conduit 2, at the level of the first internal sealing line formed by the lip or series of lips 53 located closest to the end of the male type conduit 2 or at the deepest point of the female type conduit 3, on the one hand, a blocking of the leak by the second internal sealing line made by the lip or series of lips 54 carried by the second junction joint 11b positioned at a distance from the end of the male type conduit 2 or closest to the end of the female type conduit 3 and, on the other hand, a recovery of the flowing fluid at the level of the internal drainage conduit 43 and its evacuation through the external drainage orifice 41 and the drainage channel.Indeed, the external drainage orifice 41 being positioned between the at least two lips or series of lips 51, 52 carried by the respective surfaces of each of the junction joints 11a, 11b opposite the second connection interface 31 of the female type conduit 3, the fluid flowing from the internal drainage conduit 43 is bounded between the two lips or series of lips 51, 52 and evacuated towards the external drainage orifice 41.
[0016] According to an example relating to another construction variant of the junction system according to the invention, which can be combined with some of the variants detailed previously, in section planes parallel and orthogonal to the end axis of male-type conduit 2 and arranged on either side and On the other side of the internal drainage port 42 or the internal drainage conduit 43, the surface of the first connection interface 21 has different dimensions such that, in a cross-sectional plane including the end axis of the male-type conduit 2, the surface of the first connection interface 21 has a shoulder 22. This shoulder 22 is preferably located on the outer surface of the male-type conduit 2 in the form of an annular peripheral arrangement. This shoulder 22 is likely to have a slope or inclination in a cross-sectional plane including the end axis of the male-type conduit 2.According to a particular, or even preferred, example of this construction variant, the shoulder 22 is formed at the orifice at the end of the male conduit such that the dimensions of the outer peripheral surface are smaller near the end of the male conduit 2 and larger further from this end. This configuration of the shoulder 22 allows for an increase or widening of the male conduit 2 as it moves away from its end. The compressive force exerted by the first connection interface 21 of the male conduit 2 against the junction device 11 thus increases with the depth of insertion of the male conduit 2 into the junction device 11, and is greater further from the orifice at the end of the male conduit 2.Also, the second internal sealing line formed by the lip or series of lips 54 of the junction device 11 positioned at a distance from the orifice at the end of the male conduit 2 or at the deepest point of the female type conduit 3, supports a greater compressive force allowing to optimize the resistance of the junction device 11 to the pressure of the flowing fluid in the event of a leak at the level of the first internal sealing line formed by the lip or series of lips 53, so that the sealing of the junction between the junction device 11 and the first connection interface 21 of the male type conduit 2 is improved.
[0017] According to an example relating to another specific construction variant of the previously detailed junction system construction variant, in a sectional plane comprising the end axes of the male and / or female type conduits 3 and / or the axis of the junction device 1 and / or the insertion axes of these different parts between them, the shoulders 22, 32 respectively carried by the first connection interface 21 and the second The connection interface 31 exhibits complementary shapes. These shoulders 22, 32 are thus likely to have substantially similar, or even identical, slopes or inclinations, so that the annular spacing or the separation distance between the surfaces of the two conduits, male 2 and female 3, intended to receive the axial elastic intermediate connecting device 11, is substantially constant. Therefore, the compression exerted by the two conduits, male 2 and female 3, against the surfaces of the connecting device 11 is substantially homogeneous between, on the one hand, the end of the connecting device 11 positioned deep within the female conduit 3 and, on the other hand, the end of the connecting device 11 positioned at the orifice of the female conduit 3.The elastic properties of the material of the junction device 1 1 allow the junction device 1 1 to adapt to the variation in shape or dimension of the annular spacing between the surfaces of the two conduits, male 2 and female 3, between its end deep in the female type conduit 3 and its end at the orifice of the female type conduit 3.
[0018] The invention also relates to a module for a heat exchange assembly of at least one battery cell, comprising at least: - a heat exchange panel 7 comprising an internal volume for the circulation of a heat transfer fluid between at least one inlet orifice 71 and an outlet orifice 72 of the fluid, at least one of the inlet orifices 71 and outlet 72 being associated with an axial portion 2, 3 of a respective duct arranged along an axis substantially orthogonal to the plane of the heat exchange panel 7, - a support structure 6 having a substantially planar arrangement of dimensions similar to the heat exchange panel 7 against which the support structure 6 is intended to be positioned and comprising at least one orifice 61 forming a housing of complementary shape to the peripheral edge of at least one battery cell, at least one peripheral edge of the support structure 6 carrying at least one axial portion of conduit 2, 3 arranged opposite and coaxially with the axial portion of conduit 2, 3 of an inlet orifice 71 or outlet 72 of the heat exchange panel 7, the axial portions of conduits 2, 3 arranged opposite each other having male / female type arrangements, characterized in that at least one of the pairs of axial portions of conduits 2, 3 arranged opposite each other is assembled by a joining system according to the invention. Within the framework of a heat exchanger assembly module according to the invention, at least two elements contributing to the construction of this module, namely the heat exchanger panel 7 and the support structure 6, carry sections of piping 2, 3 for the circulation of a heat transfer fluid. These piping sections 2, 3 are respectively oriented along axes substantially orthogonal to the mean plane of the heat exchanger panel 7 and / or to the mean plane of the support structure 6, by means of a connection via a junction system according to the invention. In a preferred construction example, the axial sections of conduit, male 2 or female 3, respectively associated with an inlet 71 or outlet 72 of the heat exchanger panel 7 and fixed to this opening 71, 72 of the heat exchanger panel 7, are structurally integrated into a frame 73 that surrounds, or even frames, the peripheral edge of the heat exchanger panel 7.The various axial portions of the male 2 or female 3 conduit of the heat exchange panel 7 are preferably made of the same material as the frame 73. For example, this material could be a plastic such as a thermoplastic or a metal such as aluminum. However, other materials could also be considered.
[0019] According to an example relating to a variant construction of the module according to the invention, the heat exchange panel 7 and the support structure 6 respectively carry, at a peripheral edge, on the one hand, an axial portion of a male-type duct 2 and, on the other hand, an axial portion of a female-type duct 3, each of these duct portions 2, 3 carried by a first element of the heat exchange panel 7 and the support structure 6 being arranged to be positioned opposite a complementary duct portion carried by the second element of the heat exchange panel 7 and the support structure 6. It should be noted that, at the level of the heat exchange panel 7, a portion of the axial duct portions of Male 2 and / or female 3 conduits are positioned opposite the heat transfer fluid inlet 71 and / or outlet 72 ports within the internal volume of the heat exchanger panel 7. The other portion of the axial sections of the male 2 and / or female 3 conduits is attached to piping elements 74, allowing fluid circulation independently of the internal volume of the heat exchanger panel 7. These piping elements 74 are simply supported by the heat exchanger panel 7. Similarly, at the level of the support structure 6, the axial sections of the male 2 and / or female 3 conduits are all attached to piping elements 64, which are also simply supported by the support structure 6. These piping elements 64 and 74 thus participate only in the creation of a portion of the fluid circulation circuit around the periphery of the module and / or around the periphery of a group of modules. assembled.These channeling elements 64, 74 thus allow the circulating fluid to pass through the thickness of a heat exchange panel 7 or a support structure 6 without interacting with other parts or sections of the heat exchange panel 7 or the support structure 6. It should be noted that these channeling elements 64, 74 are preferably made of the same material as the support structure 6 or the reinforcement 73 of the heat exchange panel 7. For example, this material could be a plastic such as a thermoplastic or a metal such as aluminum. However, other materials could also be considered.It should be noted that, in addition to alignment with the inlet 71 and / or outlet 72 of the heat exchange panel 7, the peripheral positioning of the duct portions 2, 3 also allows, on the one hand, to limit the bulk of the central part of the heat exchange panel 7 which is essentially intended to carry out a heat exchange with at least one battery cell positioned on the support structure 6 and, on the other hand, to facilitate access to the ends of these duct portions 2, 3 for a manipulator, in particular in the context of an assembly of the elements of the module or the junction system according to the invention, or even in the context of maintenance of the module or the system.
[0020] According to an example relating to another construction variant of the module according to the invention, which can be combined with either of the variants As previously detailed, the heat exchange panel 7 and the support structure 6 carry, on the one hand, two axial portions of male type duct 2 and, on the other hand, two axial portions of female type duct 3, these portions of duct 2, 3 being arranged symmetrically in pairs on the respective peripheries of the heat exchange panel 7 and the support structure 6, each of these portions of duct 2, 3 carried by a first element among the heat exchange panel 7 and the support structure 6 being arranged to be positioned opposite a complementary portion of duct 2, 3 carried by the second element among the heat exchange panel 7 and the support structure 6.Such a symmetrical distribution of the conduits 2, 3 on the heat exchange panel 7 and the support structure 6 allows a variation of the possible assemblies with, on the one hand, a first assembly in which the heat exchange panel 7 and the support structure 6 have similar orientations and, on the other hand, a second assembly in which one of the elements between the heat exchange panel 7 and the support structure 6 is reversed symmetrically with respect to its orientation in the first assembly.
[0021] According to an example relating to another construction variant of the module according to the invention capable of being combined with one or the other of the variants previously detailed, at least an axial portion of conduit 2, 3 relating to a piping element 64, 74 carried by the support structure 6 or by the heat exchange panel 7 and allowing fluid circulation in complete independence from the support structure 6 or the internal volume of the heat exchange panel 7, is mounted movable relative to the element, support structure 6 or heat exchange panel 7, which carries it in an arrangement allowing a pivoting inside a cone of revolution whose axis is perpendicular to the plane of the element, support structure 6 or heat exchange panel 7, which carries it and whose apex is positioned in the thickness of the element, support structure 6 or heat exchange panel 7, which carries it.This mobility of the axial portion of the conduit 2, 3 relative to the element, support structure 6 or heat exchange panel 7, which carries it, thus allows an inclination of the axial portion of the conduit, male 2 or female 3, relative to the perpendicular to the average plane of the element which it. This involves modifying the angle of the axial portion of the duct, male 2 or female 3, relative to the support structure 6 or the heat exchange panel 7. This inclination of the axial portion of the duct, male 2 or female 3, allows for adjustment of its axis so that it is coaxial with the axis of the complementary axial portion of the duct carried by the adjacent element, the support structure 6 or the heat exchange panel 7. This adjustment of the axial portion's axis corrects any misalignment resulting from the tight tolerances during the manufacturing of these module components, namely the support structure 6 and the heat exchange panel 7.Furthermore, this angular adjustment also allows the position tolerances of the different axial portions of the duct to be completed between them carried by the same support structure 6 or the same heat exchange panel 7 to facilitate the assembly by axial insertion of the different axial portions of the duct positioned on the same face of the support structure 6 with those positioned on the same face of the heat exchange panel 7.
[0022] According to an example relating to a specific construction variant of the previously detailed module construction variant, the module is characterized in that: - at least one axial portion of duct 2, 3 carried by the element, support structure 6 or heat exchange panel 7, which carries it, has a cylindrical arrangement whose outer surface includes a substantially flat relief 66 arranged in a plane orthogonal to the axis of the portion of duct 2, 3 and fixed with the portion of duct 2, 3, - the element, support structure 6 or heat exchange panel 7, which carries at least one axial portion of duct 2, 3, is made in the form of at least two frame elements 671, 672 juxtaposed within the thickness of the element, support structure 6 or heat exchange panel 7, which carries at least one axial portion of duct 2, 3, these frame elements 671, 672, on the one hand, respectively comprising at least one through orifice 68 with dimensions greater than those of the cylindrical axial portion of duct 2, 3 to be traversed by this portion of duct 2, 3 and, on the other hand, forming between them a housing 673 for receiving the relief 66 plane carried by the outer surface of the axial cylindrical portion of duct 2, 3, the width of the housing 673 along the axis of the thickness of the element, support structure 6 or heat exchange panel 7, which carries at least one axial portion of duct 2, 3 being greater than the thickness of the relief 66 plane carried by the outer surface of the portion of duct 2, 3. According to this construction variant, the mechanism enabling the duct portion 2, 3 to be pivoted relative to the element, support structure 6 or heat exchange panel 7, which carries at least one axial portion of duct 2, 3, involves the free mounting of the duct portion 2, 3 inside a through orifice 68 of this element, support structure 6 or heat exchange panel 7. The duct portion 2, 3 includes a peripheral raised portion 66 fixed with the rest of the duct portion 2, 3. This peripheral raised portion 66 has a substantially planar arrangement disposed in a plane perpendicular to the mean axis of the duct portion 2, 3 and is arranged to be locked inside a larger housing 673 integrated into the element, support structure 6 or heat exchange panel 7, which carries at least one axial portion of duct 2, 3.This housing 673 also communicates with the through opening 68 through which the portion of duct 2, 3 is positioned so that the positioning of the peripheral raised portion 66 inside the housing 673 positions the portion of duct 2, 3 through the through opening 68 of the element, support structure 6 or heat exchange panel 7, which carries the axial portion of duct 2, 3. The peripheral raised portion 66 being fixed with the rest of the portion of duct 2, 3, a deflection of this peripheral raised portion 66 inside the housing 68 jointly causes a displacement of the portion of duct 2, 3 relative to the element, support structure 6 or heat exchange panel 7, which carries the axial portion of duct 2, 3.The housing 673 being formed by two frame elements 671, 672 juxtaposed from the element, support structure 6 or heat exchange panel 7, which carries the axial portion of duct 2, 3 and positioned opposite each of the faces of the peripheral raised portion 66 of the portion of duct 2, 3, the portion of duct 2, 3 positioned through the through orifice 68 is thus mounted loosely on the element, structure of. support 6 or heat exchange panel 7, which carries this axial portion of duct 2, 3. Indeed, a displacement of the portion of duct 2, 3 along the axis of this portion is limited by the inner surfaces of the frame elements 671, 672 which form the housing 673 and block the displacement of the peripheral raised portion 66 of the portion of duct 2, 3. Similarly, a displacement of the portion of duct 2, 3 in a plane perpendicular to the axis of the portion of duct 2, 3 is limited by the inner edge of the through orifice 68 as soon as the peripheral surface of the portion of duct 2, 3 comes into contact with the inner edge of this through orifice 68.Also, the displacement of the peripheral portion in relief 66 of the portion of conduit 2, 3 inside the housing 673 of the element, support structure 6 or heat exchange panel 7, which carries this axial portion of conduit 2, 3, only allows a hinge of the portion of conduit 2, 3 inside a cone of revolution whose apex is positioned at the intersection of the axis of the portion of conduit 2, 3 with the through orifice 68.
[0023] According to an example relating to a construction variant forming an alternative to the construction variant of the module detailed previously, the module is characterized in that: - at least one axial portion of duct 2, 3 carried by the element, support structure 6 or heat exchange panel 7, which carries this axial portion of duct 2, 3 has a cylindrical arrangement whose outer surface includes a peripheral groove 65 disposed in a plane orthogonal to the axis of the portion of duct 2, 3, - the element, support structure 6 or heat exchange panel 7, which carries at least one axial portion of duct 2, 3, includes a through orifice 68 with dimensions, on the one hand, smaller than those of the outer peripheral surface of the cylindrical axial portion of duct 2, 3 and, on the other hand, larger than those of the inner peripheral surface of the peripheral groove 65 so as to be, on the one hand, traversed by this portion of duct 2, 3 and, on the other hand, positioned inside the groove 65, the width of the groove 65 being greater than the thickness of the element, support structure 6 or heat exchange panel 7, which carries this axial portion of duct 2, 3, at the level of the through orifice 68 along an axis parallel to the axis of this orifice 68. According to this construction variant, the mechanism allowing a ball joint of the portion of duct 2, 3 with respect to the element, support structure 6 or heat exchange panel 7, which carries this axial portion of duct 2, 3, also involves the free mounting of the portion of duct 2, 3 inside a through orifice 68 of this element 6,7. The portion of duct 2, 3 includes a peripheral groove 65. This groove 65 is thus arranged in a plane perpendicular to the mean axis of the portion of conduit 2, 3 and is arranged to form a housing which receives the inner edge of the through orifice 68 carried by the element, support structure 6 or heat exchange panel 7, which carries the axial portion of conduit 2, 3, so that this element, support structure 6 or heat exchange panel 7, is blocked inside the groove 65 by the peripheral edge of its orifice 68.The element, support structure 6 or heat exchange panel 7, which carries the axial portion of duct 2, 3, can be made up of at least two parts assembled together. Each of these parts then carries a portion of the inner edge of the through orifice 68, so that the orifice 68 is formed by the assembly of these at least two parts of the element, support structure 6 or heat exchange panel 7, which carries the axial portion of duct 2, 3. Also, the assembly of the at least two parts of the element, support structure 6 or heat exchange panel 7, which carries this axial portion of duct 2, 3, is carried out around the groove 65 of the portion of duct 2, 3.The dimensions of the groove 65 and the inner edge of the through-hole 68 are respectively defined to allow movement of the duct portion 2, 3 relative to the element, support structure 6 or heat exchange panel 7, without extraction of the portion of this element, support structure 6 or heat exchange panel 7, which forms the inner edge of the hole 68, from the groove 65. The duct portion 2, 3 positioned through the through-hole 68 is thus mounted loosely on the element, support structure 6 or heat exchange panel 7. The displacement of the duct portion 2, 3 along its axis is limited by the respective edges of the peripheral groove 65 which, at the peripheral edge of the through-hole 68, comes into contact with the respective surfaces of the element, support structure 6 or heat exchange panel 7, which carries the axial portion of duct 2, 3. Also, only one. The articulation of the portion of conduit 2, 3 inside a cone of revolution whose apex is positioned at the intersection of the axis of the portion of conduit 2, 3 with the through orifice 68 of the element, support structure 6 or heat exchange panel 7, is mechanically permitted.
[0024] According to an example relating to another construction variant of the module according to the invention capable of being combined with either of the variants detailed above, the module comprises two heat exchange panels 7 positioned against each other and held together in position by a frame 73 positioned on at least a part of the periphery of each of the two heat exchange panels 7, on the one hand, the inlet ports 71 and, on the other hand, the outlet ports 72 of each of the heat exchange panels 7 being respectively positioned opposite each other, the frame 73, on the one hand, integrating the axial portions of conduit 2, 3 positioned opposite each of the inlet ports 71 or outlet ports 72 of the heat exchange panel 7 and, on the other hand, comprising a drainage channel in communication with the volume 75 between the two heat exchange panels thermal 7.Preferably, the two heat exchange panels 7 have substantially similar shapes and dimensions to facilitate their assembly side-by-side, framed by a structure 73, for the construction of this variant of the module of the invention. The integration of two heat exchange panels 7 into a single module allows for efficient heat exchange on the two faces opposite the faces facing each other. Furthermore, the juxtaposition of these two heat exchange panels 7 allows for heat exchange, firstly, with at least one battery cell housed in the support structure 6 of the module and, secondly, with at least one battery cell housed in the support structure of the juxtaposed module. The juxtaposition of the two heat exchange panels 7 may also involve the use of insulating material in the space 75 separating these two panels 7.This insulating material thus makes it possible to limit, or even prevent, any unwanted heat exchange between the heat transfer fluids circulating in each of the two heat exchange panels 7. According to a construction example, to limit the risk of leakage, the volume 75 which separates the two heat exchange panels. The thermal barrier 7 is partitioned by at least one annular weld made along the peripheral edge surrounding the two opposing surfaces of these two panels 7, so that any fluid leakage within this separation volume 75 is prevented from dispersing. To prevent unnecessary fluid accumulation within this separation volume 75, the peripheral sealed joint includes a discharge conduit 751 connected to a drainage channel. Preferably, this discharge conduit 751 is positioned at a portion of the peripheral sealed joint intended to be located in the lower part of the separation volume 75. The drainage channel is thus situated below the lower part of the separation volume 75. This arrangement has the advantage of utilizing gravity to direct the fluid towards the drainage channel.The structural integration of the drainage channel into the structure of the frame 73 allows for easier assembly of the various elements that constitute the module, in particular by limiting the number of parts to be assembled since the assembly of each of the heat exchange panels 7 with the peripheral frame 73 leads to the positioning of the drainage channel and the evacuation conduit 751 in relation to the volume 75 separating the two heat exchange panels 7. As a further example, this drainage channel can be associated with a fluid detector so that a characterization of a heat transfer fluid circulating in this channel can indicate the presence of a leak at the level of one or the other of the heat exchange panels 7 that border the separation volume 75.
[0025] According to an example relating to another construction variant of the module according to the invention, which can be combined with either of the variants detailed above, at least one inlet 71 and / or outlet 72 of at least one heat exchange panel 7 is associated with one end of an axial portion of a male-type conduit 2 welded to the heat exchange panel 7 on the periphery of the inlet 71 or outlet 72. The peripheral surface of the axial portion of the male-type conduit 2 is associated, on the one hand, with an annular seal 17 and, on the other hand, with a reinforcement 731 or portion 731 of reinforcement fixed tightly against the surface of the heat exchange panel 7 and surrounding the annular seal 17 in compression against The peripheral surface of the axial portion of the male-type conduit 2, the reinforcement 731 defining with a portion of the surface of the heat exchange panel 7 at its junction with the axial portion of the male-type conduit 2 at least one discharge conduit 44 in communication with a drainage channel carried by a portion of the reinforcement 731. According to this construction variant, at least one heat exchange panel 7 of the module has an inlet 71 or outlet 72 associated with an axial portion of the male-type conduit 2. The inner edge of one end of this axial portion of the male-type conduit 2 is thus fixed by welding to the periphery of the inlet 71 or outlet 72 of the heat exchange panel 7.This weld between the heat exchanger panel 7 and the axial portion of the male-type duct 2 may be formed by one or more annular weld lines around the inlet 71 or outlet 72, so as to create a first sealing line between the heat exchanger panel 7 and the axial portion of the male-type duct 2. The axial portion of the male-type duct 2 is also associated with an annular seal 17, for example, elastic and similar in shape to an O-ring. This annular seal 17 is positioned against the peripheral surface of the male-type duct 2, near the junction of the male-type duct 2 with the heat exchanger panel 7. The axial portion of the male-type duct 2 is also associated with a reinforcement 731 or a portion of reinforcement 731 mounted on the heat exchanger panel 7.This reinforcement 731 or portion 731 of reinforcement surrounds at least the outer surface of the annular joint 17 by means of a surface forming a flat integrated into the structure of the reinforcement 731 or the portion 731 of reinforcement. The reinforcement 731 or portion 731 of reinforcement frames the peripheral surface of the annular joint 17 by its flat side to maintain this annular joint 17 in a compression position against the peripheral surface of the male-type conduit 2. The reinforcement 731 or a portion 731 of reinforcement thus has an orifice 7318 arranged concentrically with the annular joint 17 to be traversed by the male-type conduit 2. Preferably, the orifice 7318 of the reinforcement 731 or portion 731 of reinforcement has a cross-section of shape substantially identical, or even similar, to that of the annular joint 17 and also complementary to the cross-sectional shape of the male-type conduit 2. The reinforcement 731 or portion 731 of reinforcement being mounted. welded, directly or indirectly, to the heat exchange panel 7 along an annular line which surrounds the inlet 71 or outlet 72 orifice, associated with the male type conduit 2, the annular seal 17 in compression against the peripheral surface of the male type conduit 2 thus creates a second sealing line between the heat exchange panel 7 and the axial portion of the male type conduit 2. Also, a leak at the welded junction between the axial portion of the male type conduit 2 and the heat exchange panel 7 forming the first sealing line will lead to a flow of heat transfer fluid in the volume 8 defined by the heat exchange panel 7, the axial portion of the male type conduit 2, the annular seal 17 and the reinforcement 731 or the portion 731 of reinforcement. This volume 8 is also in communication with a drainage channel carried by part of the reinforcement 731 or portion 731 of reinforcement by means of an evacuation conduit 44.For example, this drain duct 44 can be formed by the sealed joining of two walls: on the one hand, the heat exchange panel 7 and, on the other hand, the reinforcement 731 or portion 731 of reinforcement. Preferably, this drain duct 44 is positioned at the lower part of the volume 8 defined by the heat exchange panel 7, the axial portion of the male-type duct 2, the annular seal 17, and the reinforcement 731 or portion 731 of reinforcement. The drainage channel is thus located at a level lower than the lower part of this volume 8 so that, by gravity, the fluid present in this volume 8 flows towards the drainage channel.The structural integration of the drainage channel into the structure of the reinforcement 731 or the reinforcement section 731 facilitates the assembly of the various elements that constitute the module, notably by limiting the number of parts to be assembled or mounted on the heat exchange panel 7. Mounting the reinforcement 731 or the reinforcement section 731 with the annular seal 17 on the heat exchange panel 7 thus creates the volume 8 defined by the heat exchange panel 7, the axial portion of the male-type conduit 2, the annular seal 17, and the reinforcement 731 or the reinforcement section 731, as well as the drain conduit 44, while simultaneously positioning the drainage channel. As a further example, this drainage channel can be associated with a fluid detector so that the presence of a heat transfer fluid circulating in this channel can be detected. of a leak at the junction between the heat exchange panel 7 and the axial portion of the male type duct 2. It should also be noted that the reinforcement 731 or portion 731 of reinforcement which is involved in this construction variant is likely to be structurally integrated into the reinforcement 73 which surrounds, or even frames, the peripheral edge of the heat exchange panel 7.
[0026] According to an example relating to another specific construction variant of the construction variant of the module previously detailed, the frame 73 carrying at least one axial portion of female type duct 3 and / or the heat exchange panel 7 being associated with an axial portion of female type duct 3, the drainage channel associated with the axial end of female type duct 3 is common or connected with the drainage channel of the frame 73 in communication with the volume 75 between the two heat exchange panels 7 and / or with the drainage channel of the frame 731 in communication with the junction between the heat exchange panel 7 and the axial portion of male type duct 2.
[0027] Of course, the invention is not limited to the embodiments described and shown in the accompanying drawings. Modifications remain possible, particularly with regard to the composition of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
