    [0001] The present invention claims the priority of French patent application No. 0957165 filed on October 13, 2009, the content of which (text, design and claims) is incorporated herein by reference.
    [0002] The present invention relates to a cooling device for a hybrid vehicle, comprising a thermal motor coupled to an electric machine and electrical energy storage means, such as a battery for example. The cooling of the different electrical members, the electrical energy storage means and the thermal motor is ensured by the circulation of a heat transfer fluid in the heat exchangers. The invention also relates to a radiator intended to be fitted to a hybrid vehicle.
    [0003] Hereinafter, for the sake of clarity of exposure of the invention, the electrical energy storage means will simply be referred to as a battery, although said means may comprise several batteries and / or one or more super-capacity (s) for example. In a hybrid vehicle, a supplementary battery, dedicated to supply electricity to the electric motor, is normally used. Its storage capacity is much higher than that of the usual battery and therefore tends to heat up, since it is much more requested than in a vehicle that does not include a thermal engine. The battery, having an ideal operation in a defined temperature range, usually centered around 40 ° C, it will be necessary to cool in order to keep its temperature close to 40 ° C. For this, it will be possible to use an air or a cooling system. heat carrier fluid or a refrigerant fluid. In the case of a heat carrier or coolant fluid, a cooling circuit equipped with a heat exchanger (a radiator) is used in which a heat carrier or coolant fluid circulates.
    [0004] Other electrical elements of the vehicle will also have to be cooled (for example the electric traction motors or motors, an inverter, etc.) in order to operate in an ideal temperature range, usually centered at 60 ° C. Another circuit cooling / cooling system equipped with a heat exchanger is then used.
    [0005] Likewise, the thermal motor needs to be cooled, in order to operate in a classical manner in a temperature range close to 80 ° C. Another cooling circuit, with a heat exchanger, will then be used.
    [0006] Three cooling circuits are therefore generally used, therefore three heat exchangers, operating in different temperature ranges. This solution allows to optimize the cooling but requires the addition of heat exchangers and the creation of independent cooling circuits. It will therefore be very advantageous to reduce the number of heat exchangers and, more generally, to modify the said cooling circuits in order to reduce costs and space under the hood.
    [0007] It will also be possible to use the refrigerant fluid from the air conditioning circuit for vehicles equipped with air conditioning. However, as before, it will need a dedicated cooling circuit. Furthermore, this solution generates a higher energy consumption caused by the operation of the air conditioning compressor.
    [0008] Figure 1 to be described later illustrates the solution o known by the state of the art (for the use of independent cooling circuits in which a heat transport fluid circulates) allowing to easily understand the drawbacks presented by the state of the art.
    [0009] According to the invention, when the battery is cooled by a heat transport fluid, the use of a heat exchanger is shared between the thermal engine and the battery according to the vehicle's operating conditions. The invention exploits the fact that the elements to be cooled do not generally work, and therefore do not need to be cooled at the same time (for example, when the thermal motor works, the electric traction motor is stopped, and vice versa).
    [00010] One of the objectives of the invention is therefore not to use just a radiator and share as much as possible the elements already present in the space under the hood of a hybrid engine (for example, the motor-fan group and the degassing box for filling ). For this purpose, the cooling device according to the present invention uses only a heat exchanger separated into three parts. Furthermore, the device according to the invention comprises means for allowing the heat transport fluid to circulate from one cooling circuit to another circuit.
    [00011] More precisely, the invention relates to a cooling device for the thermal engine, electrical components and electrical energy storage means of a hybrid vehicle, said device comprising a first circuit for cooling said engine thermal, a second circuit for cooling said electrical components and a third circuit for cooling said electrical energy storage means, a heat transport fluid which can circulate in said circuits comprising the heat exchange means. According to the invention, said heat exchange means consist of a heat exchanger separated into three parts: a high temperature HT part connected to said first circuit, a low temperature BT part connected to the second circuit and a part of very TBT low temperature connected to the third circuit.
    [00012] Furthermore, the device comprises means for placing said first circuit with said third circuit located above and beside said HT part of the heat exchanger, said communication means situated beside and being activated according to the temperature of said heat transport fluid at the level of said communicating means and said communication means located above and being activated according to the flow rate of the heat transport fluid in said first circuit.
    [00013] According to a configuration of the invention, said means placed in communication from said first circuit to the third circuit located above said heat exchanger comprise a double valve closing said first circuit and allowing the passage of the heat transport fluid from the said third circuit for said HT part of the heat exchanger, when the flow rate of the heat transport fluid in said first circuit is less than a predetermined flow. Said means of communication from said first circuit to the third circuit located next to said heat exchanger comprise a double thermostatic valve closing the first circuit and allowing the passage of heat transport fluid from said first circuit in said third circuit when the temperature of the temperature transport fluid at the level of the thermostatic valve is below the ideal operating temperature of the said electrical energy storage means.
    [00014] Said first circuit may comprise a water pump, a water outlet box, said box communicating partly with a pump and a heater for heating the passenger compartment of the vehicle and partly with the entry of the HT part of the heat exchanger through a duct connected between the outlet of said water outlet box and the entry of said HT part. Said duct comprises said double valve located substantially at the entrance to said HT part and the outlet of said HT part being connected to said pump by a conduit comprising said thermostatic valve located substantially at the outlet of said HT part of the heat exchanger.
    [00015] Said third circuit may comprise said means of storing electric energy, a pump and said TBT part of the heat exchanger, the inlet of said pump being connected to the outlet of the heat transfer liquid, the storage means of electrical power and the pump outlet being connected to the entry of said TBT part. The output of said TBT part may be connected on one part to the first circuit by means of a thermostatic valve and on the other part to the said electrical energy storage means. The entry of said TBT part may be connected to said first circuit through said valve located substantially at the entrance of said HT part.
    [00016] Said second circuit may comprise said BT part of said thermal exchange means, a pump, an inverter, an electrical machine and a device for stopping and automatically starting the thermal motor.
    [00017] Advantageously, said first and third circuits comprise in common a degassing box.
    [00018] Said electrical energy storage means may comprise at least one battery.
    [00019] According to another embodiment of the invention, each of the TBT, HT and BT parts comprises a heat transfer fluid inlet box, a radiator and a heat transport fluid outlet box.
    [00020] The inlets of the TBT and HT parts may comprise a common passage that can be closed by a valve and allowing a part of the heat transport fluid to circulate from the TBT inlet box to the HT box, and the outlet boxes the TBT and HT parts may comprise a common passage that can be closed by a thermostatic valve and allowing a part of the heat transport fluid to circulate from the HT outlet box to the TBT outlet box.
    [00021] When the flow of heat transport fluid in said first circuit for the cooling of the thermal engine is lower than a predetermined value, said valve opens said common passage of the inlet boxes allowing part of the transport fluid of heat from said TBT inlet to pass through said HT inlet. The valve closes the first circuit when the flow rate of the heat transport fluid in said thermal engine cooling circuit is substantially zero.
    [00022] Said thermostatic valve opens the common passage between the HT and TND parts of the said outlet boxes and closes the outlet of the HT box when the temperature of the heat transport fluid at the outlet of said HT part is below one predetermined temperature and vice versa, said thermostatic valve closes the common passage between said HT and TBT parts of said outlet parts and opens the outlet of the outlet box HT when the temperature of the heat transport fluid leaving the outlet box HT is higher than said predetermined temperature, which may be roughly equal to the ideal operating temperature of said electrical energy storage means.
    [00023] The first circuit for cooling the thermal engine comprises a thermostatic valve located at the outlet of the water outlet box and allowing to stop the circulation of the heat transport fluid in said first circuit when the temperature of the heat transport fluid in the said water outlet box is below the ideal operating temperature of the thermal engine.
    [00024] The invention also relates to a radiator in which a heat transfer liquid can circulate and intended to be fitted to a hybrid vehicle. According to the invention, the radiator comprises three parts separated from each other by a shield, each of said parts comprising an inlet box provided with a heat transport fluid inlet, and a heat exchanger and an outlet box provided of a heat transfer fluid outlet, one of the screens separating the inlet boxes between two adjacent parts comprising a first passage and said screen separating the outlet boxes between said two adjacent parts comprising a second passage, the first means of obturation being able to have two positions, one position by which the entrance and a box is opened and said first passage is closed and another position by which the entrance of an entrance box is closed and said first passage is opened, the two secondary ones. shutter means having two positions, a position through which the exit of an outlet box is opened and said second passage not closed and another position by which the outlet of said box is closed and said second passage being opened.
    [00025] Said means of closure may comprise an effective double valve that can change the position when the pressure exerted on the valve is substantially zero and said secondary means of closure can comprise a thermostatic valve that can change the position substantially at 40 °.
    [00026] Other advantages and characteristics of the invention will become apparent, with a detailed explanation of it in relation to the attached drawings, presented in an exemplary and non-limiting character, in which:
    [00027] - Figure 1 schematically illustrates a classic device known for the state of the art;
    [00028] - Figures 2 and 3 schematically illustrate two configurations of a device according to the present invention; and
    [00029] - Figures 4 and 5 schematically illustrate a configuration of a radiator according to the invention.
    [00030] The device illustrated in Figure 1 represents a proposed cooling configuration of different members of a hybrid vehicle. The latter comprises a thermal motor 10, equipped with a water outlet box (bucket) 12, an electrical machine 14 (usually the vehicle's electric drive motors or motors), a gearbox (gearbox) 16 and electrical energy storage means 18 (which may consist, for example, of one or more batteries of one or more super-capable (s)). For the sake of clarity, the means of storage of electrical energy will be designated hereinafter by the term "battery", being understood that this term covers all types of electrical energy storage media.
    [00031] The hybrid vehicle comprises three different cooling circuits: a first circuit 20 dedicated to cooling thermal engine 10 (this circuit being also called HT circuit for High Temperature) and represented in Figure 1 and the following figures in three planes: one second circuit 22, represented twice in full lines (also called BT circuit for Low Temperature), for the cooling of electrical components and a third circuit 24 (also called circuit for Very Low Temperature), represented with hyphens, for cooling the battery 18. Said electrical components generally comprise said electrical machine 14, an inverter 26, and often an automatic stop and start system 28 (commonly known as "Stop & Start"). A heat-carrying fluid (usually a mixture of water and glycol, for example, 50% water and 50% glycol) can circulate in the three circuits according to the directions indicated by the arrows.
    [00032] With respect to the first circuit 20 (HT circuit), the heat transport fluid circulates in the thermal motor 10 and leaves the motor through the water outlet box (bucket) 12 (note: it is usually called the outlet box) , serving as a coolant outlet that is not usually pure water). Box 12 comprises two outlets: an outlet 30 that can be closed with the aid of a thermostatic valve 32 and an outlet 34. Flowing through outlet 34, the heat-transferring fluid is aspirated by a pump 36 (electric pump for example), then sent to a heater 38 in order to heat the passenger compartment of the vehicle.
    [00033] Before penetrating heater 38, the heat-transferring fluid may eventually pass through a heater 40, which may be in the form of an electric or gasoline boiler. Leaving the heater 38, the fluid is directed to a pump 42, generally called << water pump »from where it returns to the thermal engine. A degassing box 44, common to the first circuit 20 and the second circuit 22, is used to evacuate the gas possibly present in the heat carrier fluid and to complete the level of heat carrier fluid in the cooling (refrigeration) circuits 20 and 22 Leaving through outlet 30 of the water outlet box 12, the heat transfer fluid passes through a heat exchanger 46 (HT for High Temperature), usually a radiator placed on the front face of the vehicle, after passing through the water pump 42 before resuming to the thermal motor 10. A bypass allows the fluid to return to the water outlet box 12 when the thermostatic valve 32 closes the outlet 30.
    [00034] The second circuit 22 (BT circuit), for the cooling of the electrical components, comprises a heat exchanger 48, usually a radiator (also called BT exchanger or BT radiator for Low Temperature). The heat transfer fluid is put into circulation in this second circuit 22 with the aid of an electric pump 50, the fluid then successively passing through the pump 50, the inverter26, the electric machine 14, the automatic stop and start system 28 of the motor thermal and BT 48 radiator.
    [00035] The third circuit 24 (TBT circuit) comprises a heat exchanger or radiator 52 or TBT (TBT for Very Low Temperature), the heat transport fluid being driven by an electric pump 54 to pass successively through the TBT 52 radiator and the battery 18. Thus, the fluid does not pass through the battery itself, but through the heat exchange means to cool the battery, for example a copper tube in the form of a serpentine around the battery.
    [00036] The temperature HT of the heat transfer fluid present in the first circuit 20 may vary from 70 to 110 ° C, the thermostatic valve 32 closing the outlet 30, and therefore closing the circulation of the heat transport fluid in the first circuit HT, when the temperature of the fluid in the HT circuit is below the ideal operating temperature of the thermal motor, usually 80 ° C.
    [00037] The temperature of the heat-transfer fluid present in the second 22 BT circuit is generally maintained at approximately 60 ° C, the ideal operating temperature of the electrical machine 14.
    [00038] The temperature of the heat-transfer fluid in the third circuit 24 TBT is generally maintained at approximately 40 ° C, the ideal operating temperature of temperature 18.
    [00039] These differences in the ideal operating temperature of the thermal engine, the electric machine and the battery are the cause of the use of three different cooling circuits, therefore of three radiators, which increases the manufacturing costs of the vehicle by increasing the space under the hood.
    [00040] Figure 2 schematically represents a first configuration of the invention in which the use of a heat exchanger between the thermal engine and the battery is shared according to the vehicle's operating conditions. In this Figure, the elements common to those in Figure 1, will be designated by the same reference numbers. There are three cooling circuits: the second circuit 22 (BT circuit) being identical and comprising, previously, a radiator 48, an electric pump 50, an inverter 26, an electrical machine 14 and a Stop & Start or 28 system.
    [00041] The first circuit 60 (HT circuit) is identical to the first circuit 20 of Figure 1, except that the first circuit 60 of Figure 2 comprises an effective double valve 62 placed above (in the direction of circulation of the heat-carrying fluid) the radiator 46 (HT radiator) and a thermostatic valve 64 placed next to the HT radiator. More precisely, valve 62 is located in a conduit 66 connecting the outlet of the water outlet housing 12 to the radiator HT. Furthermore, a duct 66 connects the duct 70 connecting the pump 66 in relation to the valve 62 so that when the valve 62 closes the duct 66, the heat transfer fluid can flow from the duct 68 to the HT radiator, and vice versa , when valve 62 is open, the communication between conduit 66 and the radiator HT will be open following the communication between conduit 68 and the radiator HT being closed.
    [00042] The thermostatic valve 64 is located next to the HT radiator in a conduit 72 connecting the outlet 74 of the HT radiator to the water pump 42. The TBT circuit comprises a duct 76 connecting the conduit to the battery 18, the conduit 76 evacuating in the pipeline 72 at the level of the thermostatic valve 64 so that, when the valve 64 closes the pipeline 72, the heat-carrying fluid leaving the radiator HT can pass in the pipeline 76, and vice versa, when the valve 64 does not close the pipeline 72 , the heat transfer fluid exiting the HT radiator will not pass through conduit 76.
    [00043] The third circuit 78, intended for cooling the battery 18, comprises the radiator TBT 52, a duct 80 (connecting the outlet 82 of the radiator 52 to the duct 68), the duct 76, the battery 18 (more generally the means of electrical energy storage) and the pump 54 connected to the battery 18 via the conduit 84 is connected to the inlet 86 of the TBT radiator via the conduit 70.
    [00044] Radiators 52, 46 and 48 may advantageously be formed from a single heat exchanger 58 separated into three distinct parts in order to form the three radiators 52 (TBT), 46 (HT and 48 (BT).
    [00045] As previously, the HT circuit (or first circuit) is represented in continuous full lines, the BT circuit (or second circuit) being represented in double lines and the TBT circuit (or third circuit) with hyphens.
    [00046] The effective double valve 62 allows the communication of the first circuit 60 with the third circuit 78 when the flow rate of the heat-carrying fluid in the conduit 72 is weak, practically zero. This situation occurs when the thermostatic valve 32 closes the outlet 30 of the water outlet box 12, which occurs when the temperature of the heat transport fluid in the water outlet box 12 is below the ideal operating temperature of the thermal motor. This ideal operating temperature can be, for example, between 80 to 110 ° C. In this case, outlet 30 will be opened when the temperature of the heat-transfer fluid is equal to or higher than, for example, 80 ° C and outlet 30 being closed when the fluid temperature is below 80 ° C.
    [00047] When valve 32 closes the outlet of the water outlet box, valve 62 opens the communication from plumbing 68 to the radiator HT, thus putting the third circuit 78 (TBT) in communication with the first circuit 60 (HT) . The effective double thermostatic valve 64 is calibrated to open the pipe 72 at a predetermined temperature, simply corresponding to the ideal operating temperature of the battery 18. This temperature could be, for example, approximately 40 ° C.
    [00048] A device according to the invention works differently according to the conditions of use of the vehicle. As an example: ■ First conditions of use: • thermal engine little requested or in the case stopped; • reheater 40 in the case of stopped or little used; • electric machine 14 in case it is stopped or running; • battery charge 18 from the electrical sector.
    [00049] At a temperature of the heat carrier fluid below 80 ° C in the HT circuit, the thermostatic valve 32 is closed: the heat carrier fluid provided by the thermal motor 10 being sent directly to the heater 40 and the heater 38 to heat the passenger compartment of the vehicle. The heat-transferring fluid does not pass through the HT radiator, the flow in the pipeline 66 is null: the valve 62 is therefore in a closed position (no pressure exerted above). The heat transfer fluid of the third circuit 78 (TBT) then passes through the HT radiator and then through the TBT radiator. This improves the cooling of the battery 18 by increasing the heat transfer fluid exchange surface in the heat exchanger 88. The temperature in the third TBT circuit does not exceed 40 ° C, when the thermostatic valve 64 is in the closed position: it allows to resend the heat carrier fluid leaving the HT radiator to battery 18. The thermostatic valve 64 also prevents any risk of sending the heat carrier fluid to a temperature above 40 ° C, in battery 18, which degrades its performance and / or duration of life. The flow in the third TBT circuit is ensured by the electric pump 54, the cooling of the battery being ensured when the thermal motor is stopped.
    [00050] These operating conditions correspond to the moments when the battery needs to be cooled, where the resources for a surface of the heat exchanger are most important during this period. ■ Secondary conditions of use: • thermal engine 10 running; • reheater 40 in operation or stopped; • electrical machine 14 stopped or little requested; • battery charge 18 with the thermal engine power.
    [00051] When the thermal motor needs to be cooled, for heat transport fluid temperatures above 80 ° C in the first HT circuit, the thermostatic valve 32 opens. Under the pressure of the heat-transferring fluid, valve 62 also opens, closing the duct 76. The heat-transferring fluid provided by the thermal motor 10 is cooled in the HT radiator. The temperature at the outlet 74 of the HT radiator is higher than 40 ° C, the thermostatic valve 64 also opens, allowing the fluid to be sent back to the thermal motor through the duct 72. The battery 18 is then cooled only by the TBT radiator, the valve 62 and the thermostatic valve 64 closing the pipes 68 and 76 connecting the third TBT circuit to the HT radiator.
    [00052] These two operating conditions correspond to the moments when the battery 18 recharges from the power of the thermal motor 10. It therefore proposes to ensure a minimum cooling of the battery. The need for cooling being less important than in the first conditions, the heat exchange surface of the TBT radiator is sufficient.
    [00053] Figure 3 schematically illustrates a second configuration of the invention. This configuration incorporates the same elements as the configuration represented in Figure 2, these common elements being designated by the same reference numbers. The differences between the two configurations refer to the heat exchanger (framed as an oval 88), valve 62 and thermostatic valve 64. Heat exchanger 88 is formed of a single radiator divided into three parts TBT, HT and BT. Valve 62 and thermostatic valve 64 are in this second configuration integrated in the radiator HT. This arrangement allows notably to simplify the HT and TBT circuits, the communication between the HT and TBT circuits being carried out in the heat exchanger 88, and more precisely between the HT and TBT parts of the heat exchanger, in view of the use of a new type of radiator represented by the Figures 4 and 5. It can be seen in Figure 3 that the outlet 74 of the HT radiator is connected directly to the water pump 42, that the communication duct 68 and part of the duct 76 have been suppressed.
    [00054] The heat exchanger 88 is represented schematically in Figure 4 which represents a situation in which the temperature of the heat-transfer fluid in the HT circuit is below the ideal operating temperature of the thermal motor (for example below 80 ° C). Exchanger 88 is a "complex" radiator with changes in the refrigerant between the TBT and HT parts. This radiator consists of three parts: - a TBT (Very Low Temperature) part 90; - an HT (High Temperature) part 92, and - a BR (Low Temperature) part 94. The TBT and HT parts are separated by a bulkhead 96, and the HT and BT parts are separated by a bulkhead 98.
    [00055] Each of these parts comprises a heat transfer fluid inlet box (100 for the TBT part, 102 for the HT part, and 104 for the BT part), a heat exchange part (106 for the TBT part, 108 for the HT part and 110 for the BT part) and an outlet box (112 for the TBT part, 114 for the HT part and 116 for the BT part). The heat-carrying fluid in the directions indicated by the arrows, the hyphens for the TBT part, and full lines for the HT part and in double lines for the BT part.
    [00056] Each of the inlet boxes 100, 102 and 104 are provided with a heat transfer fluid inlet 118, 120 and 122 respectively. Each of the outlet boxes 112, 114 and 116 comprise a fluid outlet, respectively 124 , 126 and 128. The bulkhead 96 separating the TBT and HT parts comprises a first communication passage 130 between the input boxes 100 and 102 and a second communication passage 132 between the output boxes 112 and 114. The passage 130 is provided first closure means 134 having two positions, one is the position in which the inlet 120 of the inlet box 102 is opened and the first passage 130 is closed and another position in which the inlet 120 of the inlet box 102 is closed and the first passage 130 being opened.
    [00057] The passage 132 is provided with secondary closing means 136 and can have two positions, one position in which the outlet 126 of the outlet box 114 is opened and the second passage 132 being closed, and another position in which the outlet 126 is closed and the second passage 132 is opened.
    [00058] The closure means 134 may comprise an effective double valve equivalent to valve 62 of the configuration of Figure 2, that valve closing the inlet 120 and opening the passage 130 when the flow in the pipe 72 is very weak, almost zero, and therefore when the temperature of the heat transfer fluid is below 80 ° C, for example (temperature at which the thermostatic valve 32 closes the outlet 30 of the water outlet box).
    [00059] The closing means 136 may comprise a thermostatic valve identical to the thermostatic valve 64 of the configuration of Figure 2. That valve closes the outlet 126 and opens the passage 132 when the temperature of the heat-transfer fluid in the outlet box 114 is lower at the ideal operating temperature of battery 18, for example 40 ° C.
    [00060] The conditions for circulating the TBT circuit carrier liquid in the HT radiator are as follows: when the thermostatic valve 32 of the water outlet box closes the outlet 30; the flow rate in the radiator HT 108 will be null, the valve 134 closes the inlet of the radiator HT and the passage 130 is opened; the input boxes 100 and 102 communicating and the heat transfer fluid then passing through the HT circuit. The fluid contained in the HT 108 radiator will cool. Since the temperature of this fluid is below 40 ° C, the thermostatic valve 136 opens the passage 13e and closes the outlet 126 of the radiator HT. The heat transfer fluid of the TBT circuit can then circulate in the HT circuit, more precisely in the radiator 108 of the HT circuit.
    [00061] Figure 5 represents the radiator of Figure 4, when the thermostatic valve 32 of the water outlet box is in the open position, that is, when the outlet 30 is open. This corresponds to a coolant temperature greater than or equal to the ideal operating temperature of the thermal engine (for example 80 ° C). There will be no circulation of heat transfer fluid from the TB circuit to the HT circuit. In effect, valve 134 closes passage 130 and opens inlet 120 of radiator HT 108. Thermostatic valve 136 (open to approximately 40 ° C) is opened, that is, opening outlet 126 of radiator HT and closing passage 132 There is therefore no communication between the TBT and HT circuits. This results in the HT radiator being used for cooling the thermal engine.
    [00062] The advantages sought by the present invention are for example and in a non-limiting way: - intelligent thermal management of the cooling circuit; - sharing the radiator to cool different members operating at very different temperature margins; - the absence of the supplementary heat exchanger, on the front face of the vehicle or in another part of the vehicle; - the absence of the additional motor-fan group and the use of the main motor-fan group on the facade; - the installation of the cooling circuit in the vehicle is easier due to the small space of the radiator of the invention compared to the three radiators known in the art; - the electrical consumption of the cooling circuit is small compared to the electrical consumption of an air or refrigerant cooling circuit.
    [00063] Other configurations of those described and represented may be known to a person skilled in the art, aware of the state of the art, without departing from the scope of the present invention.
