Description

Title of the invention: MODULAR THERMAL MANAGEMENT SYSTEM FOR MOTOR VEHICLES AND VEHICLE INCLUDING SUCH A SYSTEM

[0001] The present invention relates to the field of thermal management systems for motor vehicles, and more particularly to a modular thermal management system that can be modified according to different types of architectures and refrigerants.

[0002] The term "thermal management system" means a loop comprising various heat exchangers, expansion devices, etc., in which a refrigerant circulates, which allows other fluids, such as water, air, etc., to be heated and / or cooled for thermal management of the various components and / or volumes of the vehicle, for example an engine (electric and / or thermal), a passenger compartment, a traction battery, etc.

[0003] Current thermal, electric or hybrid motor vehicles thus include one or more thermal systems for the thermal management of the various components of the vehicle, and these can have varied architectures using different refrigerants, such as 1234YF, R134A or R744 (CO2).

[0004] The architectures of said systems may be so-called "direct" architectures or so-called "indirect" architectures, as well as intermediate architectures between these two types of architecture. It should be noted that a direct architecture is understood to mean that heat exchangers of said thermal management system directly thermally condition the fluids that heat or cool the components and / or volumes of the vehicle, while an indirect architecture is understood to mean that heat exchangers of said thermal management system thermally condition one or more intermediate fluids (generally of a separate thermodynamic loop) that heat or cool a fluid that thermally conditions the components and / or volumes of the vehicle.

[0005] The various components or parts forming the architectures of thermal management systems are scattered throughout the engine compartment and connected to each other by means of pipes. Current thermal management systems are therefore not compact.

[0006] Furthermore, there is an evolution in the type of refrigerant used in the thermal management systems of motor vehicles, with the refrigerants used having characteristics that are as harmless as possible to the environment, in particular by altering the ozone layer as little as possible, not aggravating the greenhouse effect and / or not containing perfluoroalkyl and polyfluoroalkyl substances (or PFAS) considered to be at risk to flora and fauna.

[0007] Thus, the most commonly used refrigerants currently are R134a, R1234YF, and R744 (or carbon dioxide), but R290 (or propane) is a refrigerant that could potentially replace the aforementioned refrigerants in the future. Unfortunately, R290 has the problem of being highly flammable; therefore, specific integration measures must be implemented in the vehicle to ensure passenger safety.

[0008] One of the requirements for using R290 as a refrigerant in a vehicle thermal management system is, among other things, to have the various components of said system in a closed and sealed module.

[0009] It is therefore necessary that the thermal management system be compact, unlike thermal management systems using other types of refrigerant, where the various components are located all over the vehicle's engine compartment.

[0010] Furthermore, in view of the uncertainties on regulatory developments regarding the use of R290 as a refrigerant or another type of refrigerant, car manufacturers are seeking to design thermal management systems that can be adapted to different refrigerants, preferably for the same vehicle platform, while respecting regulatory safety requirements and space requirements.

[0011] The present invention thus aims to remedy at least one of the aforementioned drawbacks by proposing a new type of modular thermal management system for motor vehicles, said system comprising a box configured to accommodate various elements intended to form a thermal conditioning loop in which a refrigerant circulates, said system comprising the following elements: - at least one compressor forming a first module; - at least one heat exchanger, referred to as the first exchanger, and an expansion device forming a second module, said first exchanger being configured to thermally condition (for example cool) one or more components and / or volumes of a vehicle; - at least one interface room in which refrigerant fluid pipes are installed; the said first and second modules being housed in the box, the said box comprising a plurality of means of fixing for the securing of one or more elements and / or modules inside the said box.

[0012] The system according to the invention thus has the advantage of housing one or more system elements in a box, while comprising elements arranged in the form of modules that attach to said box via at least one interface piece. The system is therefore more compact, more efficient, more effective, and less expensive, while also allowing for adaptability of said system at the architectural level and / or to the type of refrigerant (R290, R134A, 1234YF, or R744) through the modules installed in the box of said system according to the invention. This is further enhanced by ensuring the safety of vehicle passengers, particularly when the refrigerant is R290.

[0013] It should also be noted that an element, such as a compressor, an exchanger, etc., is understood to "form" a module in the sense that said module includes at least this or these elements, said module being able to include additional elements (such as pipes).

[0014] According to one possible characteristic, said box is closed and sealed. The box is a closed volume, advantageously made of metal (for example steel, aluminum, etc.) or plastic, with sealed openings provided in one or more walls of the box, in order to allow pipes to pass through the wall or walls of said box.

[0015] According to another possible feature, the first heat exchanger is a fluid-fluid type heat exchanger connected to a heat exchanger located outside the box. The first module thus comprises a first heat exchanger associated with an expansion device, for example upstream of said first heat exchanger, so that the refrigerant of the first heat exchanger is able to absorb heat from the other fluid, for example a heat transfer fluid. The heat exchanger located outside the box connected to the first heat exchanger is, for example, a heat exchanger intended to thermally condition a traction battery of a motor vehicle.

[0016] According to another possible feature, said system comprises: - additional components housed in the box, said additional components include for example pressure-reducing devices, valves, pipes and / or check valves, etc.; - a second heat exchanger configured to heat one or more components and / or volumes of a vehicle; - a third heat exchanger configured to cool one or more components and / or volumes of a vehicle; Advantageously, said system may include additional exchangers housed or not in the system box, in order to heat and / or cool certain components and / or volumes of said vehicle, and allow a high degree of modularity and adaptability of the system depending on the vehicle in which said system is installed.

[0017] According to another possible feature, the second and third exchangers are housed in the box and form respectively a third module and a fourth module, said heat exchangers housed in the box being fluid-fluid exchangers connected respectively to a fluid-air heat exchanger located outside the box, said additional components forming in combination with the first, second, third and fourth modules, a thermal conditioning loop having an architecture called "indirect".

[0018] Thus, the box of said system can accommodate up to four modules, each module having a specific function, and whose combination forms an indirect architecture. The system according to the invention, in indirect architecture, allows the use of any type of refrigerant, such as R290, 1234YF, R134A, or R744.

[0019] According to another possible feature, the second exchanger is housed in the box and forms the third module, the third exchanger being located outside the box, the second exchanger being a fluid-fluid type exchanger connected respectively to a fluid-air heat exchanger located outside the box, the third exchanger being a fluid-air type exchanger, said additional components and the third exchanger forming in combination with the first, second and third modules, a thermal conditioning loop having a so-called "semi-indirect" architecture.

[0020] Thus, in another possible arrangement of the system according to the invention, the third exchanger is disposed outside the box of the system according to the invention and replaced by additional components, so that the system according to the invention forms a so-called "semi-indirect" thermal conditioning loop.

[0021] It should be noted that the first, second and third modules are always housed in the system box, in the same position and preferably have the same technical characteristics and / or the same components (or at least similar or equivalent) as for the first architecture.

[0022] It should be noted that the architecture can be modified by adding pipes and components to said box, for example in the form of a link module taking the place of the fourth module and / or by a specific arrangement of said at least one interface piece.

[0023] According to another possible feature, the system comprises a fourth heat exchanger configured to thermally condition an airflow, the second, third, and fourth exchangers being disposed outside the box, the second exchanger being a fluid-fluid type exchanger, the third and fourth exchangers being fluid-air type exchangers, said additional components and said second, third, and fourth exchangers forming in combination with the first module and the second module, a thermal conditioning loop featuring a so-called "direct" architecture.

[0024] Thus, in another possible arrangement of the system according to the invention, the third and fourth modules are located outside the system box according to the invention and replaced by additional components, so that the system according to the invention forms a so-called "direct" thermal conditioning loop. It should be noted that the first and second modules are still housed within the system box, in the same position, and preferably have the same technical characteristics and / or the same components (or at least similar or equivalent components) as in the first and / or second architectures.

[0025] It should be noted that the architecture can be modified by adding pipes and components to said box, either in the form of a link module taking the place of the third and / or fourth module, or by a specific arrangement of said at least one interface piece.

[0026] According to another possible feature, said additional components include pressure-reducing devices, valves, pipes and / or check valves.

[0027] According to another possible feature, the system includes a reservoir bottle or an accumulator disposed directly upstream of the compressor.

[0028] According to another possible feature, the system includes a reservoir or accumulator located directly downstream of the second heat exchanger. It should be noted that the position of the reservoir or accumulator depends on the refrigerant used in the system, as well as the system's configuration.

[0029] According to another possible feature, said system is configured, on the one hand, to accommodate a predetermined number of modules, and, on the other hand, to present predetermined volumes and / or spaces for the installation of identical or similar (or equivalent) modules according to the architecture of said system.

[0030] Thus, modules comprising one or more additional components and / or organs, but whose function in the system is identical or equivalent, regardless of the system architecture, are arranged in a predetermined volume or space in the box of said system.

[0031] The invention also relates to a motor vehicle, for example a hybrid, electric or thermal vehicle, characterized in that said vehicle includes a thermal management system as defined above.

[0032] The invention will be better understood, and other objects, details, features and advantages thereof will become more apparent from the following description of a particular embodiment of the invention, given solely by way of illustration and not limitation, with reference to the accompanying drawings, in which: - Fig. 1 illustrates a functional schematic view of a thermal management system according to the invention arranged according to a first architecture; - [Fig.2] is a very schematic view of the spatial arrangement of the elements of the system in [Fig.1]; - [Fig.3] is a schematic, partial and perspective view of the system of [Fig.1]; - Fig. 4 illustrates a functional schematic view of a thermal management system according to the invention arranged according to a second architecture; - the [[Fig.5]] is a very schematic view of the spatial arrangement of the elements of the system of the [[Fig.4]]; - Fig. 6 illustrates a functional schematic view of a thermal management system according to the invention arranged according to a third architecture; - the [[Fig.7]] is a very schematic view of the spatial arrangement of the elements of the system of the [[Fig.6]]; - the [[Fig.8]] is a schematic functional representation in linear form of the system of the [Fig.6].

[0033] In the following description, the term "include" is synonymous with "include" and is not limiting in that it permits the presence of other elements in the vehicle, or the structure to which it relates. It is understood that the term "include" includes the terms "consist of".

[0034] In this description, "placed upstream" means that an element is positioned before another with respect to the direction of fluid flow. Conversely, "placed downstream" means that an element is positioned after another with respect to the direction of fluid flow.

[0035] Furthermore, in the present description, when an element is disposed "directly upstream" or "directly downstream", it is understood that no other element having an effect on the pressure and / or temperature of the refrigerant is disposed in the path of the refrigerant between the two elements concerned.

[0036] Fig. 1 thus illustrates a schematic functional view of a thermal management system 1 according to a first architecture of the invention intended to equip a motor vehicle, for example a hybrid, electric or thermal vehicle.

[0037] Said system 1 thus includes a box 3 which is configured to accommodate various elements connected to each other, by pipes 4, to form a thermal conditioning loop 2 in which a refrigerant fluid, such as R290, R744, R134A or 1234YF, circulates.

[0038] Said box 3 is advantageously a closed and sealed volume (or envelope), particularly with respect to the refrigerant circulating in the conditioning loop thermal 2. The said box 3 is for example made of metal, such as steel, aluminum, etc., or of a plastic material.

[0039] In addition, said box 3 has sealed openings 3a arranged at the level of one or more of its walls through which pipes 4 of heat transfer fluid or refrigerant fluid can pass.

[0040] Said thermal loop 2 thus comprises, in the direction of circulation of the refrigerant fluid, connected to each other by pipes 4, a compressor 5, a heat exchanger 7 configured to heat one or more components of a vehicle, two heat exchangers 9 and 11 which are mounted in parallel with each other and which are configured to cool one or more components and / or distinct volumes of the vehicle.

[0041] Said loop 2 further includes a reservoir bottle 13 disposed directly upstream of the compressor 5, the compressor 5 forming with (or without) the reservoir bottle 13 a first module Mi housed in the box 3.

[0042] Said loop 2 comprises a first expansion device 15 disposed directly upstream of the heat exchanger 9 (and downstream of the compressor 5), referred to as the first heat exchanger, configured to thermally condition, such as by cooling, one or more components and / or volumes of the vehicle, for example, a traction battery of the vehicle. The first heat exchanger 9 and the first expansion device 15 form a second module M2 housed in the box 3.

[0043] The heat exchanger 7, referred to as the second exchanger, is located directly downstream of the compressor 5 and is, for example, a fluid-fluid type exchanger. This means that the second exchanger carries both the refrigerant from loop 2 and a third fluid, such as a heat transfer fluid, from a secondary loop. The second exchanger 7 transfers heat from the refrigerant to the third fluid in the secondary loop. Furthermore, the second exchanger 7 forms a third module M3 housed within the box 3.

[0044] In the embodiment described herein, the second exchanger 7 is connected to a secondary heat exchanger 16 located outside the box 3 which is configured to heat certain components and / or volumes of the vehicle, either directly by means of said heat transfer fluid, or indirectly by heating, by means of the heat transfer fluid, a third fluid, such as air.

[0045] Said loop 2 comprises a first expansion device 17 disposed directly upstream of the exchanger 11, referred to as the third heat exchanger, configured to cool one or more components and / or volumes of the vehicle, for example a passenger compartment of vehicle. The third exchanger 11 and the second expansion device 17 form a third module M3 housed in box 3.

[0046] It will be noted that the first and third exchangers 9 and 11 are for example a fluid-fluid type exchanger, that is to say that the first 9 and third 11 exchangers are each an exchanger in which the refrigerant of loop 2 circulates, but also a fluid, for example a heat transfer fluid, from a third or secondary loop, each of the first and third exchangers 9 and 11 allowing to capture heat from the heat transfer fluid of a secondary loop to the refrigerant (thus to cool the third fluid of the secondary loop).

[0047] In the embodiment described herein: - the first exchanger 9 is connected to a secondary heat exchanger 19, located outside the box 3, which is configured to cool certain components and / or volumes of the vehicle, either directly by means of the heat transfer fluid (from the secondary loop), or indirectly by cooling, by means of the heat transfer fluid, a third fluid, such as air; - the third exchanger 11 is connected to a secondary heat exchanger 21, located outside the box 3, which is configured to cool certain components and / or volumes of the vehicle, either directly by means of the heat transfer fluid (from the secondary loop), or indirectly by cooling, by means of the heat transfer fluid, a third fluid, such as air.

[0048] Advantageously, the first and third heat exchangers 9 and 11 are configured to cool separate components and / or volumes of the vehicle, including components and / or volumes requiring thermal conditioning incompatible with each other, such as a vehicle passenger compartment and a traction battery.

[0049] In addition, the reservoir bottle 13 is arranged downstream of the first and third exchangers 9 and 11, the arrangement of the various components forming the thermal conditioning loop 2 in which the refrigerant circulates undergoing a thermodynamic cycle to transfer and / or capture heat from other fluids.

[0050] Figure 2 illustrates a very schematic view of the spatial arrangement of the elements of loop 2 of system 1 according to the first architecture. System 1 thus comprises at least one interface piece 23 which is housed in box 3 and in which at least some of the refrigerant lines 4 of loop 2 are located.

[0051] Said system 1 further comprises fastening means for securing one or more components (or elements) and / or modules Mi to M4 inside said box 3. Said fastening means are, for example, provided on said at least one interface piece 23 and / or on at least one of the walls of the box 3. Said fastening means are, for example, screw-nut systems, bolts, clips, etc., both that the means of fixing are reversible and allow the assembly and disassembly of said Mi to M4 modules (or elements) to allow their interchangeability (or replacement).

[0052] Thus, the first, second, third and fourth modules Mi to M4 are housed in the box 3 and fixed to one or more walls of the box 3 and / or said at least one interface piece 23, this by means of suitable fixing means.

[0053] Fig. 3 is, for its part, a schematic, partial and perspective view of the different modules Mi to M4 housed in box 3, and which are fixed to the interface piece 23 and / or to box 3.

[0054] The entire set of modules Mi to M4 is thus grouped in a predefined volume delimited by the walls of the box 3. The system 1 may also include a support plate 25 on which to fix certain elements of the system 1, such as the compressor 5.

[0055] Said first, second, third and fourth modules Mi to M4 form, by their combination, a thermal conditioning loop called "indirect", that is to say that the system 1 thus arranged forms a loop 2 presenting a first architecture which is a so-called "indirect" architecture.

[0056] It should be noted that in an unrepresented variant of the first architecture, system 1 does not include the third module M3 (i.e. the branch of the loop including the third exchanger and the second expansion device, nor the associated secondary exchanger).

[0057] The box 3 of said system 1 can thus accommodate up to four modules Mi to M4, each of the modules Mi to M4 having a specific function, the combination of which forms an indirect architecture. The system 1 in indirect architecture allows the use of any type of refrigerant, such as R290, 1234YF, R134A or R744.

[0058] Figure 4 illustrates a functional schematic view of a system thermal management 1 according to a second architecture, the so-called "semi-indirect" architecture. While [Fig.5] is a schematic view of the spatial arrangement of the elements of loop 2 of system 1 according to this second architecture.

[0059] The second architecture of system 1 is substantially equivalent to the first architecture described in [Fig.1] and [Fig.2], with the difference that the third exchanger 11 of the fourth module M4 has been removed from box 3 and placed outside box 3, said third exchanger 11 still being mounted in parallel with the first exchanger 9.

[0060] The third exchanger 11 is, for example, a fluid-air type exchanger, the air circulating through the third exchanger 11 serving, for example, to thermally condition a passenger compartment of a motor vehicle, the second expansion device 17 is still housed in box 3 (and positioned directly upstream of said third exchanger 11).

[0061] System 1 therefore no longer includes a third module M3 arranged in box 3, but the first, second and third modules Mi to M3 in combination with the third exchanger 11 thus form a so-called "semi-indirect" thermal conditioning loop.

[0062] It will be noted that the first, second and third modules Mi to M3 are always housed in box 3 of system 1, in the same positions and preferably have the same components (or equivalents) with technical characteristics identical or similar to those of system 1 arranged in an indirect architecture (or first architecture).

[0063] The architecture of system 1 can thus be modified very simply to go from a direct architecture to a semi-indirect architecture, and thus allow the use of 1234YF, R134A or R744 as refrigerant (this in a more efficient way).

[0064] Figure 6 illustrates a functional schematic view of a thermal management system 1 according to a third architecture, the so-called "direct" architecture. Figure 7, on the other hand, is a schematic view of the spatial arrangement of the elements of loop 2 of system 1 according to the third architecture.

[0065] The third architecture of system 1 is substantially equivalent to the second architecture of system 1 described in [[Fig.4]], with the difference that: - the second exchanger 7 is located outside the box 3 and is advantageously configured to heat an airflow intended to heat one or more components and / or volumes of the vehicle; - a fourth heat exchanger 27 is located outside the box 3 and is configured to thermally condition an airflow for the thermal management of one or more components and / or volumes of the vehicle; - there is the addition of additional components, such as a pressure-reducing device 29, two valves 31 and 33, pipes, as well as two check valves 35 and 37.

[0066] The third architecture of system 1 thus forms a so-called "direct" thermal conditioning loop. Figure 8 is a very schematic linear representation of system 1 arranged in the third architecture.

[0067] Indeed, the loop 2 thus comprises in the direction of circulation of the refrigerant fluid: the compressor 5, the second heat exchanger 7, two parallel branches Bi and B2, called first and second branches, joining in a node Ni connected to the reservoir bottle 13 (itself placed directly upstream of the compressor 5).

[0068] Thus, the first branch Bi comprises, in the direction of fluid flow, a first valve 31, a third expansion device 29, the fourth exchanger 27 and the first non-return valve 35. The second branch B2 comprises, in the direction of fluid flow, the second expansion device 17, the third exchanger 11 and the second valve 33.

[0069] Said loop 2 also includes: - a third branch B3 connecting the first branch Bi to the second branch B2, respectively between the first valve 31 and the third expansion device 29 at the level of the first branch Bb and between the third exchanger 11 and the second valve 33 at the level of the second branch B2; - a fourth branch B4 comprising, in the direction of fluid flow, the first expansion device 15 and the first exchanger 9, the fourth branch B4 being connected to the node Ni of junction of the first and second branches Bi and B2 which is itself connected to the reservoir bottle 13.

[0070] Said third branch B3 further includes the second check valve 37 which is configured to prevent, via the third branch B3, a reflux of refrigerant from the outlet of the third heat exchanger 11 to the first branch B1 or the fourth branch B4. Said second check valve 37 is advantageously located downstream of the junction between the third and fourth branches B3 and B4.

[0071] In this third architecture, the first exchanger 9 is advantageously a fluid-fluid type exchanger, while the third and fourth exchangers 11 and 27 are, for example, fluid-air type exchangers.

[0072] The third architecture of the thermal management system 1 thus results, in relation to the second architecture, from the removal of the first heat exchanger 7 from the box 3 and the addition of pipes and functional components in the box 3. The pipes thus added can be fitted directly into the interface piece 23 and / or be separate pieces attached to said interface piece 23 and / or to the box 3.

[0073] The various organs and conduits housed in the box 3 can also form a so-called linking module which fits and interfaces with the first and second modules Mi and M2, as well as with the interface piece 23 (the linking module, for example, takes the place of the third and / or fourth module).

[0074] It should be noted that the first and second modules Mi and M2 are always housed in box 3 of system 1, in the same position and preferably have the same (or equivalent, or similar) technical characteristics and / or identical or similar components.

[0075] The third architecture of system 1 advantageously uses R744 as the refrigerant, the compressor 5 then being adapted or replaced by a suitable compressor, but having a similar footprint to the compressors used for other types of refrigerant, such as R290, R134A or 1234YF.

[0076] In another unrepresented embodiment of system 1 arranged according to the third architecture, there is no fourth exchanger 27 as well as the associated components, i.e. the third expansion device 29, and the first non-return valve 35.

[0077] In another unrepresented embodiment of the system, the reservoir bottle or accumulator is disposed directly downstream of the second exchanger.
