Description

Title of the invention: Thermal conditioning system Technical field

[0001] The present invention relates to the field of thermal conditioning systems. These systems can in particular equip a motor vehicle. Such systems make it possible to achieve thermal regulation of different parts of the vehicle, such as for example the passenger compartment or an electrical energy storage battery, in the case of an electrically powered vehicle. Heat exchanges are managed mainly by the evaporation and condensation of a refrigerant fluid within different heat exchangers making it possible to ensure heating or cooling of different parts. Prior art

[0002] Thermal conditioning systems commonly use a refrigerant loop and a heat transfer fluid loop exchanging heat with the refrigerant. Such systems are thus called indirect. The refrigerant loop is formed so that the refrigerant transfers heat to a heat transfer fluid in a first heat exchanger. The heat transferred to the heat transfer fluid can then be dissipated in an air flow intended for the passenger compartment in order to heat it. The heat transfer fluid circuit also makes it possible to cool elements of the vehicle's powertrain that dissipate heat, such as the vehicle's electric traction motor or the power electronics controlling the electric motor. For this, another heat exchanger makes it possible to carry out a heat exchange between the heat transfer fluid and the refrigerant in order to cool the heat transfer fluid.

[0003] There is therefore a need to arrange thermal conditioning systems as compactly as possible, which can offer different modes of cooling and / or heating the battery or different elements of the vehicle's powertrain.

[0004] Thermal conditioning systems consist in particular of thermal management components, such as pumps, valves, heat exchangers, as well as components for temperature regulation. Components, such as conduits, are also provided for guiding a fluid and fluidically connecting the thermal management components to each other.

[0005] The development of electric vehicles has increased the need for optimized thermal conditioning systems with simplified and economical manufacturing processes while creating a demand for systems with reduced footprint.

[0006] However, the optimized management of space under the hood, or more generally in the vehicle, remains essential, including for electric vehicles in which new components (compared to thermal cars) are necessary.

[0007] Also the reduction of these components or their associated connections is of major interest.

[0008] The invention aims firstly to propose a solution to improve the situation. Summary

[0009] To this end, the present invention proposes a thermal regulation system for a vehicle, in particular for a hybrid or electric vehicle, the thermal regulation system comprising: - a first thermal regulation module, intended for the circulation of at least a first fluid, in particular heat transfer liquid, said first thermal regulation module extending mainly along a first plane, said first module being configured to receive at least one element with a fluidic function, such as a pump or a valve, - a second thermal regulation module, intended for the circulation of at least one second fluid, different from the first fluid, in particular the refrigerant fluid, said second thermal regulation module extending mainly along a second plane, the first and second planes being substantially parallel, said second module being configured to receive at least one element with a fluidic function, such as a pump or a valve, the thermal regulation system comprising at least one first bi-fluid heat exchanger, in particular of the liquid evaporator type, positioned at least partially between the first and second planes, in particular between the first and second modules.

[0010] The term “fluidic function” means a function participating in the operation of the assembly, for example chosen to act on the flow of a heat transfer fluid (for example a fluid flow channel) or to measure a parameter linked to the fluid or to its flow in channels.

[0011] The thermal regulation system participates in the cooling of at least one element of the motor vehicle with which it is fitted. For this purpose, it is configured to carry out a heat exchange between the first fluid and the second fluid, the heat exchange being carried out thanks to the first bi-fluid heat exchanger which it comprises.

[0013] Such a thermal regulation system makes it possible to gain in compactness, the first bi-fluid heat exchanger being positioned between the first and second modules, and the lengths of the connections between the first bi-fluid heat exchanger and the first and second modules are reduced accordingly.

[0014] According to an exemplary embodiment of the invention, the first bi-fluid heat exchanger comprises a plurality of plates which all extend in planes substantially parallel to the first and second planes.

[0023] According to an exemplary embodiment of the invention, the thermal regulation system comprises at least one internal heat exchanger, positioned at least partially between the first and second planes, in particular between the first and second modules.

[0024] According to an exemplary embodiment of the invention, the internal heat exchanger comprises a plurality of plates which all extend in planes substantially parallel to the first and second planes. More particularly, the internal heat exchanger is formed by a stack of plates which are superimposed on each other in a stacking direction substantially perpendicular to the first and second planes.

[0025] According to an exemplary embodiment of the invention, the first bi-fluid heat exchanger and the internal heat exchanger are integral. In particular, at least one end plate of the first bi-fluid heat exchanger is integral with at least one end plate of the internal heat exchanger.

[0026] According to an exemplary embodiment of the invention, the first bi-fluid heat exchanger is positioned at least partially between the internal heat exchanger and the first module.

[0028] According to an exemplary embodiment of the invention, the thermal regulation system comprises at least one second bi-fluid heat exchanger, in particular of the liquid condenser type, positioned at least partially between the first and second planes, in particular between the first and second modules.

[0029] According to an exemplary embodiment of the invention, the second bi-fluid heat exchanger comprises a plurality of plates which all extend in planes substantially parallel to the first and second planes. More particularly, the second bi-fluid heat exchanger is formed by a stack of plates which are superimposed on one another in a stacking direction substantially perpendicular to the first and second planes.

[0030] According to an exemplary embodiment of the invention, the first bi-fluid heat exchanger, the second bi-fluid heat exchanger and the internal heat exchanger are integral.

[0031] According to a particular embodiment of the invention, at least one end plate of the first dual-fluid heat exchanger is secured to at least one end plate of the internal heat exchanger, and / or at least one end plate of the second dual-fluid heat exchanger is secured to at least one end plate of the internal heat exchanger.

[0032] According to a variant of this embodiment, at least one plate of the first dual-fluid heat exchanger is the extension of at least one plate of the second dual-fluid heat exchanger. In other words, at least one plate of the first dual-fluid heat exchanger is in one piece with at least one plate of the second dual-fluid heat exchanger. According to this embodiment, a portion of the stack of plates of the first dual-fluid heat exchanger is common to the stack of plates of the second dual-fluid heat exchanger.

[0035] According to an exemplary embodiment of the invention, the projections of the bodies of the first and second bi-fluid exchangers, in a direction substantially perpendicular to the first and second planes, are included in a projection, in said direction, of the body of the internal heat exchanger.

[0036] The first bi-fluid heat exchanger, the second bi-fluid heat exchanger and the internal heat exchanger are all positioned between the first and second modules, making the thermal regulation system more compact. In addition, the assembly of the components together, in particular the positioning of the first and second bi-fluid heat exchangers between the internal heat exchanger and the first module, makes it possible to improve the compactness by reducing the volumes occupied by the heat exchangers. The volume made available between the first and second modules can then be used to house one or more elements with a fluidic function, such as a valve or a pump.

[0037] According to an exemplary embodiment of the invention, the second module is configured to receive a bottle, in particular a desiccant bottle or an accumulator.

In particular, variants of the invention may be imagined comprising only a selection of features described below in isolation from the other features described, if this selection of features is sufficient to confer a technical advantage and / or to differentiate the invention from the prior art. of the prior art.

[0058] [Fig.l] shows a thermal regulation system 1 for a vehicle, in particular for a hybrid or electric vehicle. Said thermal regulation system 1 comprises a first thermal regulation module 11, intended for the circulation of at least one first fluid, here glycolated water, said first thermal regulation module 11 extending mainly along a first plane PI. The first module is configured to receive at least one element with a fluidic function, such as a pump 13 or a valve 14.

[0059] The thermal regulation system 1 also comprises a second thermal regulation module 12, intended for the circulation of at least one second fluid, here a refrigerant fluid, said second thermal regulation module 12 extending mainly along a second plane P2, the first and second planes PI, P2 being substantially parallel. Said second module 12 is configured to receive at least one element with a fluidic function, such as a valve 14, for example an expansion device.

[0060] The expansion device used may be an electronic expansion valve, a thermostatic expansion valve, or a calibrated orifice. In the case of an electronic expansion valve, the passage section allowing the refrigerant fluid to pass through can be continuously adjusted between a closed position and a maximum open position. For this, an electronic control module drives an electric motor which moves a movable shutter controlling the passage section offered to the second fluid.

[0061] The first fluid is for example chosen from water, a mixture of water and ethylene glycol, an oil or a dielectric fluid.

[0062] The second fluid is for example chosen from a fluid R 134a, R1234yf or R744 which supplies an air conditioning loop of the vehicle.

[0063] The thermal regulation system 1 participates in the cooling of at least one element of the motor vehicle with which it is fitted. For this purpose, the thermal regulation system 1 comprises at least one first dual-fluid heat exchanger 21. The first dual-fluid heat exchanger 21 is a liquid evaporator, also called a “chiller” in English. Said first dual-fluid heat exchanger is configured to allow a heat exchange between, on the one hand, a flow of the first fluid, within the first dual-fluid heat exchanger 21, and, on the other hand, a flow of the second fluid, at low pressure and low temperature, within the first dual-fluid heat exchanger 21.

[0064] According to the illustrated embodiment [Fig.2], the first bi-fluid heat exchanger 21 comprises a plurality of plates, preferably of substantially rectangular shape, which all extend in planes substantially parallel to the first and second planes PI, P2. More particularly, the first bi-fluid heat exchanger 21 is formed by a stack of plates which are superimposed on each other in a stacking direction E substantially perpendicular to the first and second planes PI, P2.

[0065] Said first bi-fluid heat exchanger 21 is positioned at least partially between the first and second planes PI, P2, in particular between the first and second modules 11, 12.

[0066] In this way, the inlet and outlet of the first fluid of the first bi-fluid heat exchanger 21 are positioned opposite each other and directly fluidically connected to the first module, while the inlet and outlet of the second fluid of the first bi-fluid heat exchanger 21 are positioned opposite the second module.

[0067] Such a thermal regulation system 1 makes it possible to gain in compactness, the first bi-fluid heat exchanger 21 being positioned between the first and second modules, and the lengths of the connections between the first bi-fluid heat exchanger 21 and the first and second modules 11, 12 are reduced accordingly.

[0068] The thermal regulation system 1 is part of a heat pump, on board the vehicle. The heat pump is for example of the indirect type.

[0069] The thermal regulation system 1 illustrated [Fig.l] and 2 also comprises fluidic function elements. These fluidic function elements comprise: - a second bi-fluid heat exchanger 22, in particular of the liquid condenser type, - an internal heat exchanger 23, - a pump 13, - a compressor 17, - a valve 14, in particular a multi-way valve, a stop valve, a direction valve, a non-return valve, a throttle valve and / or a pressure relief device, - a sensor, in particular pressure and / or temperature, - a bottle 16 of refrigerant fluid, in particular a desiccant bottle or an accumulator, - a degassing tank 15, - a water heater, particularly a heating resistance type.

[0070] At least one element with a fluidic function is positioned at least partially between the first and second planes P1, P2, in particular between the first and second modules 11, 12. In the example illustrated, two pumps 13 and a valve 14 attached to the first module 11, and a valve 14, here an expansion device, attached to the second module 12, are positioned at least partially between the first and second modules 11, 12.

[0071] Thus, the space separating the first and second modules 11, 12 makes it possible to house one or more elements with fluidic functions, which makes it possible to improve compactness accordingly.

[0072] The first thermal regulation system 1 comprises a degassing tank 15, in particular a removable degassing tank 15, in which the first fluid can circulate to undergo degassing making it possible to separate a gas, here air, present in the first fluid.

[0073] The degassing tank 15 is preferably arranged on a face of the first module 11 opposite the second module 12.

[0074] The degassing tank 15 is fluidically connected to the first module 11.

[0075] In this way, the space between the first and second modules 11, 12 makes it possible to house at least the first bi-fluid heat exchanger 21, while the space on the other side of the first module 11 makes it possible to house the degassing tank 15.

[0076] The thermal regulation system 1 also comprises an internal heat exchanger 23. The internal heat exchanger 23 is configured to allow a heat exchange between, on the one hand, a flow of the second fluid at low pressure and low temperature, within the internal exchanger 23, and, on the other hand, a flow of the second fluid at high pressure and high temperature, within the internal exchanger 23.

[0077] The internal heat exchanger 23 is positioned at least partially between the first and second planes P1, P2, in particular between the first and second modules 11, 12.

[0078] According to the illustrated embodiment [Fig.2], the internal heat exchanger 23 comprises a plurality of plates, preferably of substantially rectangular shape, which all extend in planes substantially parallel to the first and second planes PI, P2. More particularly, the internal heat exchanger 23 is formed by a stack of plates which are superimposed on each other in a stacking direction E substantially perpendicular to the first and second planes PI, P2.

[0079] According to the illustrated embodiment [Fig.2], the first dual-fluid heat exchanger 21 and the internal heat exchanger 23 are integral. According to this embodiment, the stack of plates of the first dual-fluid heat exchanger 21 is produced in the extension of the stack of plates of the internal heat exchanger 23. In particular, at least one end plate of the first dual-fluid heat exchanger 21 is integral with at least one end plate of the internal heat exchanger 23.

[0080] In this way, the assembly formed by the first bi-fluid heat exchanger 21 and the internal heat exchanger 23 is more compact, and such an assembly makes it possible to braze the two exchangers at the same time.

[0081] The first bi-fluid heat exchanger 21 and the internal heat exchanger 23 are directly fluidically connected, in particular at the interface between said end plates. Thus, the second low-pressure, low-temperature fluid flows from the first bi-fluid heat exchanger 21 to the internal heat exchanger 23.

[0082] This first bi-fluid heat exchanger 21 / internal heat exchanger 23 assembly makes it possible to do without connections between the two and therefore to gain in compactness.

[0083] The thermal regulation system 1 also comprises a second dual-fluid heat exchanger 22. The second dual-fluid heat exchanger 22 is a liquid condenser. Said second dual-fluid heat exchanger is configured to allow a heat exchange between, on the one hand, a flow of the first fluid, within the second dual-fluid heat exchanger 22, and, on the other hand, a flow of the second fluid, at high pressure and high temperature, within the second dual-fluid heat exchanger 22.

[0084] According to the illustrated embodiment [Fig.2], the second bi-fluid heat exchanger 22 comprises a plurality of plates, substantially rectangular, which all extend in planes substantially parallel to the first and second planes PI, P2. More particularly, the second bi-fluid heat exchanger 22 is formed by a stack of plates which are superimposed on each other in a stacking direction E substantially perpendicular to the first and second planes PI, P2.

[0085] Said second bi-fluid heat exchanger 22 is positioned at least partially between the first and second planes PI, P2, in particular between the first and second modules 11, 12.

[0086] According to the illustrated embodiment [Fig.2], the first bi-fluid heat exchanger 21, the second bi-fluid heat exchanger 22 and the internal heat exchanger 23 are integral.

[0087] According to this embodiment, the stack of plates of the first dual-fluid heat exchanger 21 and second dual-fluid heat exchanger 22 are produced in the extension of the stack of plates of the internal heat exchanger 23. In particular, at least one end plate of the first dual-fluid heat exchanger 21 and at least one end plate of the second dual-fluid heat exchanger 22 are integral with at least one end plate of the internal heat exchanger 23.

[0088] In this way, the assembly formed by the first bi-fluid heat exchanger 21, the second bi-fluid heat exchanger 22 and the internal heat exchanger 23 is more compact, and such an assembly makes it possible to braze the three exchangers at the same time. time.

[0089] The first dual-fluid heat exchanger 21 and the second dual-fluid heat exchanger 22 on the one hand, and the internal heat exchanger 23 on the other hand, are directly fluidically connected, in particular at the interface between said end plates. Thus, the second low-pressure, low-temperature fluid flows from the first dual-fluid heat exchanger 21 to the internal heat exchanger 23, while the second high-pressure, high-temperature fluid flows from the second dual-fluid heat exchanger 22 to the internal exchanger 23.

[0090] This first bi-fluid heat exchanger 21 / second bi-fluid heat exchanger 22 / internal heat exchanger 23 assembly makes it possible to do without connections between the exchangers and therefore to gain in compactness.

[0091] The first dual-fluid heat exchanger 21 and the second dual-fluid heat exchanger 22 are positioned at least partially between the internal heat exchanger 23 and the first module 11. In particular, the projections of the bodies of the first and second dual-fluid exchangers 21, 22, in a direction substantially perpendicular to the first and second planes P1, P2, are inscribed in a projection, in said direction, of the body of the internal heat exchanger 23.

[0092] According to the illustrated embodiment [Fig.3], the second module 12 of the thermal regulation system 1 is configured to receive a bottle 16, in particular a desiccant bottle or an accumulator.

[0093] The first module 11 comprises an opening 31, the bottle 16 extending from the second module 12 and through said opening 31. The bottle 16 therefore extends through the first plane PL

[0094] In this way, as shown [Fig. 1], the height of the bottle 16 corresponds substantially to the height of the complete module, integrating in particular the first and second modules 11, 12 and the degassing tank 15, which makes it possible to gain in compactness.

[0095] According to the illustrated embodiment [Fig.2], the thermal regulation system 1 also comprises a compressor 17, said compressor extending at least partially between the first plane PI and the second plane P2.

[0096] According to the illustrated embodiment [Fig.4], the first module 11 comprises at least one first distribution element 111, designed substantially in the form of a plate, at least one second distribution element 112 being placed substantially in parallel with the first distribution element 111. The first module 11 comprises at least one first channel 31 and / or a first fluid inlet and / or a first fluid outlet.

[0097] The first distribution element 111 and / or the second distribution element 112 comprises at least in places a plastic material.

[0098] The fact of producing a part of the first module 11 in plastic material makes it possible to reduce its mass, while allowing great modularity of shape.

[0099] According to the illustrated embodiment, the first module 11 is a constituent element of several elements with a fluidic function, in particular a valve 14 and three pumps 13. The first module thus comprises the chamber of the valve 13 and the volutes of the pumps 13.

[0100] The second module 12 comprises at least one second channel and / or a second fluid inlet and / or a second fluid outlet.

[0101] The second module 12 comprises aluminum at least in places. This makes it possible to produce a module capable of supporting the flow of the refrigerant fluid under pressure.

[0102] Also, one or more features and / or steps disclosed only in one embodiment or example may be generalized to other embodiments. Similarly, one or more features and / or steps disclosed only in one embodiment or example may be combined with one or more other features and / or steps disclosed only in another embodiment.

[0103] The use of the verb “comprise”, “comprise” or “include” and its conjugated forms does not exclude the presence of other elements or other steps than those stated in a claim.

[0104] In the claims, any reference sign in parentheses cannot be interpreted as a limitation of the claim.
