    专利说明:

    The invention relates to a thermal management system, in particular for a hybrid-type motor vehicle. The invention relates more particularly to a thermal management system for a hybrid type of motor vehicle comprising at least one heat engine and an electric motor, said system comprising at least: a first cooling circuit for cooling the heat engine of the vehicle by circulation at least a first coolant, and - a second cooling circuit for cooling by circulation of at least a second coolant at least the electric motor and power electronics means associated with said electric motor.
    Examples of such a thermal management system (also known as "thermo-management") are known from the state of the art, in particular but not exclusively used in a hybrid-type motor vehicle.
    In the automotive field, the term "hybrid" means that the vehicle is equipped with two types of engines using two types of energy.
    A hybrid vehicle comprises in particular at least one heat engine, generally providing the energy required for the movement of the vehicle, and one or more electric motor (s) to optimize its operation.
    In known manner, there are mainly three families of motorization for hybrid vehicles, namely "micro-hybrid", "mild-hybrid" and "full-hybrid", the classification in one of said families being determined based the power of the electric motor used.
    Multiple combinations are possible in order to associate one or more electric motors with a heat engine, each having particular characteristics.
    Such "hybrid" vehicles are still referred to by the acronym "PHEV" for "Plug-in Hybrid Electric Vehicle" in English.
    The heating system of hybrid vehicles is generally identical to that of thermal vehicles, only hybrid modes of operation changing. The heating operation is determined by the operation of the heat engine to provide a heat engine cooling circuit with the calories required for heating.
    The vehicle heating system generally comprises at least one heating radiator (or "heater") which is associated with the cooling circuit of the engine. Unlike the heat engine, the energy efficiency of an electric motor is high so that it is established that there is little or no energy (calories) that can be used to heat the vehicle.
    However, it is sought to improve the thermal management in such a hybrid motor vehicle and especially to optimally provide the heating function.
    The object of the present invention is in particular to propose a new thermal management system design of a hybrid motor vehicle to improve the heating of the interior of the passenger compartment of the vehicle, while simplifying said thermal management system.
    For this purpose, the invention proposes a thermal management system of the type described above, characterized in that said second cooling circuit comprises at least one heating radiator for heating the interior of the passenger compartment of the vehicle.
    Advantageously, the first cooling circuit, said high temperature, of the heat engine and the second cooling circuit, said low temperature, associated in particular with the electric motor are independent of one another.
    Such a design of the cooling system with two independent cooling circuits, disconnected, also facilitates degassing.
    Thanks to such a system, the calories produced by the operating heat engine are recovered in order to be able to heat the interior of the passenger compartment of the hybrid type of motor vehicle. The calories recovered from the heat engine are thus added to those produced by the electric motor and the part of power electronics associated therewith.
    Advantageously, said at least one heating radiator (or "heater") is arranged in the second low temperature cooling circuit to participate selectively in said heating function of the passenger compartment. The arrangement of the heating radiator (or "heater") advantageously makes it possible to simplify the cooling system, especially the second so-called low temperature cooling circuit, in particular by reducing the number of necessary means such as solenoid valves, water pumps , degassing jars, etc.
    According to other characteristics of the invention: the second cooling circuit comprises at least one degassing jar which is mounted in parallel with said at least one heating radiator; the first cooling circuit of the heat engine and the second cooling circuit are selectively put into thermal transfer relationship through at least one water-water heat exchanger; said at least one water-water type heat exchanger is mounted in shunt with respect to the second cooling circuit; the second cooling circuit comprises heating means which are selectively controlled to heat the second cooling liquid; said heating means are arranged upstream of said at least one heating radiator for heating the interior of the passenger compartment of the vehicle; the second cooling circuit comprises means for measuring the temperature of the second cooling liquid; the second cooling circuit comprises at least one cooling radiator and a branch of the at least one radiator; the second cooling circuit comprises at least one circulator which is arranged downstream of said cooling radiator; the second cooling circuit comprises a cooling loop for cooling at least one high-voltage battery associated with said electric motor by means of said second cooling liquid. Other features and advantages of the invention will appear on reading the description which follows for the understanding of which reference will be made to the single figure which partially represents a thermal management system of a hybrid vehicle and which illustrates more particularly a second cooling circuit comprising a heater according to an exemplary embodiment of the invention.
    Diagrammatically in the single figure, a thermal management system 10 (or thermo-management) for a hybrid type of motor vehicle (not shown).
    Such a hybrid vehicle comprises a heat engine (not shown) and at least one electric motor 12.
    The thermal management system 10 of the vehicle comprises at least a first cooling circuit 14, said high temperature, for cooling the engine of the vehicle by circulating at least a first coolant.
    In the single figure, the cooling circuit 14 of the engine is not illustrated in detail and shown schematically by an arrow.
    The thermal management system 10 of the vehicle comprises a second cooling circuit 16, said low temperature.
    The second cooling circuit 16 is in particular intended to cool, by circulation of at least a second cooling liquid, at least the electric motor 12 and power electronics means 18 associated with said electric motor 1 2.
    According to the invention, the second cooling circuit 16 comprises at least one heating radiator 20, still generally called a heater, for heating the interior of the passenger compartment of the vehicle.
    In the exemplary embodiment, the second coolant of said second cooling circuit 16 is, in addition to said electric motor 12 and said associated power electronics means 18, in heat transfer relationship with at least one charger 22 and / or a 24-DC converter (DC-DC) and / or a second electric motor 26.
    The second cooling circuit 16 comprises at least one degassing jar 28 which is here connected in parallel with said at least one heating radiator 20 (or air heater).
    Advantageously, the first cooling circuit 14 of the heat engine and the second cooling circuit 16 are selectively connected in heat transfer relation through at least one water-water heat exchanger 30.
    The first cooling circuit 12 (so-called high temperature) of the heat engine in which the first cooling liquid circulates and the second cooling circuit 16 (said low temperature) in which the second cooling liquid circulates are advantageously independent of one another. 'other.
    In known manner, the cooling liquid used in a vehicle is mainly constituted by water forming the base of the coolant and to which are advantageously added additives having, for example, antifreeze and / or anticorrosive properties.
    Preferably, said at least one heat exchanger 30 of water-water type is mounted in shunt with respect to the second cooling circuit, in a branch 31 bypass (or bypass).
    Advantageously, the water-water type heat exchanger 30 makes it possible to transfer heat from the first cooling fluid of the heat engine 12 to the second cooling fluid, more particularly when the heat engine 12 is in operation.
    The second cooling circuit 16 comprises regulating means 32 arranged upstream of the heat exchanger 30 for selectively controlling the circulation of the second cooling liquid in the bypass branch 31 comprising the at least one water-water type heat exchanger 30. .
    Preferably, the regulation means 32 consist of a three-way valve.
    In a variant not shown, said water-water type heat exchanger 30 comprises integrated control means which are controlled to selectively control the circulation of said second cooling liquid in the second cooling circuit 16.
    In such a variant and in comparison with the exemplary embodiment shown in the figure, said bypass branch 31 is then omitted, the "bypass" function being directly integrated with said heat exchanger 30.
    In variant not shown, the second cooling circuit 16 may not include such a heat exchanger 30 water-water type.
    Advantageously, additional heating means are then provided to compensate for the calories from the heat engine 12 and not transmitted via said water-water type heat exchanger 30.
    Such additional heating means are integrated in the system called "C.V.C" in French and corresponding to the acronym of "Heating, Ventilation, Air Conditioning".
    It is recalled that such a system "HVAC" is also referred to in English by the acronym "HVAC" for "Heating, Ventilation, Air-Conditioning".
    Preferably, said additional heating means of the "HVAC" system (or HVAC) comprise, for example, heating elements for heating the air, in particular heating elements such as "CTP" type resistors (acronym for "Positive Temperature Coefficient"). Allowing self-regulation.
    Advantageously, the second cooling circuit 16 comprises heating means 34 which are selectively controlled to heat said second coolant.
    The heating means 34 comprise, for example, electrical resistances to form a kettle adapted to heat the second cooling liquid to a given set temperature.
    Advantageously, such heating means 34 are also likely to be used to heat the first coolant of the first cooling circuit 14 of the engine to facilitate in particular the temperature rise of said engine.
    The heat transfer is then effected in the opposite direction through the water-water type heat exchanger 30, from the second cooling liquid to the first cooling liquid of the heat engine.
    By such a warming of the first coolant by the second liquid heated by the heating means 34, it is advantageous to reduce the friction during start-up of the heat engine.
    The heating means 34 are arranged upstream of said at least one heating radiator 20 (or heater) for heating the interior of the passenger compartment of the vehicle.
    The second cooling circuit 16 comprises temperature measuring means 36 for measuring the temperature of the second cooling liquid.
    Preferably, said means 36 for measuring the temperature of the second cooling liquid are arranged upstream of said at least one heating radiator 20 and downstream of said heating means 34.
    The second cooling circuit 16 comprises at least one cooling radiator 38.
    Advantageously, the second cooling circuit 16 comprises a branch 39 bypass (or bypass) of said cooling radiator 38.
    The second cooling circuit 16 comprises control means 40, such as a three-way valve, which are arranged downstream of said cooling radiator 38.
    With said regulating means 40 and said bypass branch 39, the cooling radiator 38 is capable of being traversed by the second cooling liquid or not.
    Advantageously, the control means 40 are controlled so that the second coolant does not pass through said cooling radiator 38 to conserve the calories of said second coolant so as to use all or part of said calories to perform a function other than the sole heating the passenger compartment of the vehicle.
    This could be the case, for example, when the vehicle is used with a very low outdoor air temperature, that is to say in so-called "very cold" conditions.
    Indeed, the calories present in the second coolant are then likely to be for example also used to heat a high voltage battery associated with the electric motor.
    In the embodiment illustrated in the single figure, the second cooling circuit 16 comprises a cooling loop 42 for cooling by means of said second cooling liquid at least one battery 44, called high voltage, which is associated with said electric motor 12 .
    The second coolant is for example likely to be circulated in such a loop 42 for cooling a high voltage battery 44.
    Preferably, said loop 42 for cooling the high voltage battery 44 comprises at least one cooler 46.
    Preferably, said loop 42 for cooling the high voltage battery 44 comprises at least one circulator 48, said circulator 48 being arranged between said cooler 46 and said at least one high voltage battery 44.
    Advantageously, the loop 42 for cooling the high-voltage battery 44 comprises regulation means 50 that are selectively controlled to regulate the circulation of the coolant therein.
    The means 50 for regulating said cooling loop 42 are, for example, constituted by a three-way valve.
    The regulating means 50 make it possible in particular to selectively circulate the second cooling liquid between said loop 42 and the second cooling circuit 16. Depending on the position of the regulating means 50, said cooling loop 42 may be isolated from the second cooling circuit 16, the circulation interrupted.
    In the exemplary embodiment, the loop 42 for cooling the high-voltage battery 44 is connected to the second circuit 16 for cooling.
    In a variant that is not shown, the loop 42 for cooling the high-voltage battery 44 is independent of the second circuit 16 for cooling.
    Preferably, said loop 42 for cooling the high voltage battery 44 comprises at least means 52 for measuring the temperature.
    Advantageously, said means 52 for measuring the temperature are arranged downstream of the cooler 46, preferably downstream of the circulator 48 and upstream of the high-voltage battery 44, to measure the temperature of the second cooling liquid in said loop 42.
    Preferably, the second cooling circuit 16 comprises at least one circulator which is arranged downstream of said cooling radiator 38.
    Advantageously, the second cooling circuit 16 comprises two circulators, respectively a first circulator 54 and a second circulator 56.
    In the exemplary embodiment, the first circulator 54 and the second circulator 56 are arranged in series, downstream of said cooling radiator 38.
    In the exemplary embodiment, the two circulators 54 and 56 are arranged downstream of the regulating means 40 associated with said cooling radiator 38 and its branch 39 of bypass.
    The two circulators 54 and 56 are arranged upstream of the section of the second cooling circuit 16 comprising said at least one electric motor 12 and the associated power electronics means 18. The exemplary embodiment shown in the single figure is given as a non-limiting example of a thermal management system 10 according to the invention. The invention is susceptible of industrial application in that it concerns a thermal management system for a hybrid-type motor vehicle comprising at least one heat engine and an electric motor, said system comprising at least a first circuit 14 of cooling of the heat engine and a second cooling circuit 16 for cooling at least the electric motor 12 and associated power electronics means 18, and being characterized in that said second cooling circuit 16 comprises at least one radiator 20 of heating (or air heater) for heating the interior of the passenger compartment of the vehicle.
