Description

Title of the invention: MOTOR VEHICLE WITH HEAT TRANSFER FLUID DISTRIBUTION DEVICE WITHOUT A DISTRIBUTION VALVE

[0001] The invention relates to a motor vehicle comprising control means arranged to control at least one thermal regulation circuit comprising a heat transfer fluid circulating in at least a first loop and a second loop, said first comprising, downstream of a first inlet, a first main pipe passing through a first thermodynamic component and a first circulation pump, upstream of a first outlet of said first loop arranged to cooperate with a second inlet that said second loop comprises, said second loop comprising, downstream of said second inlet, a second main pipe passing through a second circulation pump and a second thermodynamic component, upstream of a second outlet of said second loop arranged to cooperate with said first inlet.

[0002] The invention relates to the field of circulation of the heat transfer circuit in a thermal regulation, cooling and / or heating circuit of a powertrain or engine or even a passenger compartment, in particular for a motor vehicle.

[0003] Hydraulic thermal regulation circuits are known from the prior art, with a hydraulic architecture comprising at least two heat transfer fluid loops, in particular and not limited to two water loops, where the heat transfer fluid is driven within each loop by a circulation pump. Here, the term "hydraulic circuit" refers to any circuit conveying a heat transfer fluid, whether this fluid is water, glycolated water, oil, another liquid, or even a gas.

[0004] It is desired to be able to control the connection between the two loops proportionally, so that the flow rate in a branch can vary from zero flow rate to its full nominal flow rate.

[0005] To do this, three-way proportional valves are generally used, capable of regulating the flow rate.

[0006] [Fig.l] thus illustrates a conventional assembly. A thermal regulation circuit 100 comprises a first loop 10, and a second loop 20. These loops comprise or pass through thermodynamic components which can be passive thermodynamic components such as radiators, or active thermodynamic components such as boilers, motors, or others.

[0007] By convention, hereinafter Qn is referred to as the flow rate of heat transfer fluid passing through a thermodynamic component named “n”. In the same way, we use the qualifier “first” for the elements of the first loop 10, and the qualifier “second” for the elements of the second loop 20.

[0008] The first loop 10 comprises a first inlet 101 supplying a first inlet pipe 14 crossed by a flow Q4 of heat transfer fluid, for the supply, directly or through a first intermediate thermodynamic component 4, of a first thermodynamic component 1, which the flow of heat transfer fluid passes through before entering a first circulation pump 7, from which it leaves to enter, at a first outlet junction 18, a first proportional three-way valve 6. The two outlet channels of this first proportional three-way valve 6 are, one a first bypass 17, and the other a first outlet 102 of the first loop 10. The first bypass 17 can in particular supply a first additional thermodynamic component 2 whose outlet flow is then brought back to the first thermodynamic component 1

[0009] The second loop 20 comprises a second inlet 201 partially supplied by the first outlet 102 of the first loop 10, the flow of heat transfer fluid is subjected to the action of a second circulation pump 8, to supply, with a flow rate Q3, a second thermodynamic component 3 from which it leaves, at a second outlet junction 28, to enter a second proportional three-way valve 5, the two outlets of which are, one a second bypass 106 crossed by a flow rate Q9 passing through a non-return valve 9 and bringing the fluid back to a second inlet junction 26 in the vicinity of the second inlet 201 of the second loop 20, and the other a second outlet 202 which the second loop 20 comprises, supplying the first loop 10 with the flow rate Q4. The flow rate Q3 is equal to the sum of the flow rate Q4 and the flow rate Q9.

[0010] The control of the second proportional three-way valve 5 allows an adjustment of the flow rate Q4 in the first inlet pipe 14, and an adjustment of the flow rate Q9 passing through the non-return valve 9.

[0011] The control of the second valve 5 between its minimum and maximum positions allows a proportionality of the flow rate from 0% to 100% in the first intermediate thermodynamic component 4, and vice versa in the non-return valve 9.

[0012] Such an assembly is satisfactory, but at the cost of a complex circuit and the multiplication of actuators. This thermal regulation circuit according to the prior art is therefore expensive and bulky.

[0013] The objective of the present invention is to remedy these drawbacks by proposing a simplified thermal regulation circuit, comprising fewer thermodynamic components, and saving on a proportional three-way valve.

[0014] This is in fact a question of reducing the number of actuators, and of reducing the overall cost.

[0015] The invention proposes to manage the distribution of heat transfer fluid between the two loops by controlling only the circulation pumps, without using a proportional three-way valve.

[0016] To achieve this objective, the invention proposes a motor vehicle comprising control means arranged to control at least one thermal regulation circuit comprising a heat transfer fluid circulating in at least a first loop and a second loop, said first loop comprising, downstream of a first inlet, a first main pipe passing through a first thermodynamic component and a first circulation pump, upstream of a first outlet of said first loop arranged to cooperate with a second inlet that said second loop comprises, said second loop comprising, downstream of said second inlet, a second main pipe passing through a second circulation pump and a second thermodynamic component, upstream of a second outlet of said second loop arranged to cooperate with said first inlet.

[0017] According to the invention, said control means are arranged to control the value and the distribution of the flow rates of the heat transfer fluid in said first loop and in said second loop by controlling said first circulation pump and said second circulation pump, with reference to at least one control table which said control means comprise and which comprises instructions for adjusting the speed of said first circulation pump and said second circulation pump suitable for obtaining a first flow rate in said first loop and a second flow rate in said second loop.

[0018] Thanks to the invention, expensive components are limited and the thermal regulation circuit is simplified.

[0019] Advantageously, said first loop comprises, downstream of said first inlet and a first inlet pipe entering a first inlet junction, said first main pipe passing through said first thermodynamic component and said first circulation pump to a first outlet junction upstream of a first outlet pipe leading to said first outlet of said first loop, said second loop comprises, downstream of said second inlet and a second inlet pipe entering a second inlet junction, said second main pipe passing through said second circulation pump and said second thermodynamic component to a second outlet junction upstream of a second outlet pipe leading to said second outlet of said second loop.

[0020] Thus the thermal regulation circuit lends itself to the most common variants, and makes the integration of different components easy.

[0021] Advantageously, said control means are arranged to control the value and the distribution of the flow rates of the heat transfer fluid in said first loop and in said second loop by controlling said first circulation pump and said second circulation pump, as a function of information supplied to said control means by temperature sensors included in said control means or included in said thermal regulation circuit.

[0022] Thus the control means are able to select the control table adapted to the climatic environment of the vehicle, and the temperature information recorded in the loops makes it possible to finely adjust the flow rates for the best thermal regulation.

[0023] Advantageously, said first loop comprises a first bypass pipe downstream of said first outlet junction joining said first main pipe at said first inlet junction, and / or in that said second loop comprises a second bypass pipe downstream of said second outlet junction joining said second main pipe at said second inlet junction.

[0024] This arrangement provides a universal character to the thermal regulation circuit.

[0025] Advantageously, only one of said first loop or said second loop comprises, at its outlet junction downstream of its main pipe, a proportional three-way valve, one outlet channel of which corresponds to the outlet of the loop, and the other outlet channel of which feeds a bypass pipe directly or indirectly joining its thermodynamic component or an inlet junction of the loop.

[0026] This limits us to a single proportional three-way valve for the entire thermal regulation circuit.

[0027] Advantageously, said first loop comprises a first bypass pipe which passes through an intermediate thermodynamic component upstream of the first inlet junction which is located between on the one hand said first inlet pipe of the first loop downstream of the first inlet, and on the other hand the first main pipe passing through the first circulation pump and the first thermodynamic component.

[0028] This type of assembly allows for a very sophisticated thermal regulation circuit.

[0029] Advantageously, said first outlet junction of said first loop comprises a first proportional three-way valve, a first outlet channel of which is said first bypass pipe supplying said first additional thermodynamic component upstream of said first inlet junction, and a second outlet channel of which is said first outlet pipe of said first loop.

[0030] It is thus possible to finely regulate the internal functioning of the first loop.

[0031] Advantageously, said first proportional three-way valve is the only proportional three-way valve that said thermal regulation circuit comprises.

[0032] This unique proportional three-way valve limits the overall cost of the installation.

[0033] Advantageously, said second loop comprises a second discharge pipe rivation which passes through a non-return valve upstream of the second inlet junction which is located between on the one hand said second inlet pipe of the second loop downstream of the second inlet, and on the other hand the second main pipe passing through the second circulation pump and the second thermodynamic component.

[0034] The second loop is thus simple and secure.

[0035] Advantageously, said first inlet pipe of said first loop passes through an additional thermodynamic component upstream of said first inlet junction.

[0036] This arrangement allows optimization of the first loop.

[0037] The invention will be further detailed by the description of non-limiting embodiments, and on the basis of the appended figures illustrating variants of the invention, in which: - [Fig.l] schematically illustrates a motor vehicle comprising a thermal regulation circuit according to the prior art, with a first loop and a second loop each comprising a proportional three-way valve; - [Fig.2] schematically illustrates a motor vehicle comprising a thermal regulation circuit according to the invention in a basic execution in which the first loop and the second loop are each without a proportional three-way valve, and where the control of the circuit is carried out by controlling the flow rate in each loop by controlling the speed of its circulation pump on the basis of a control table; - [Fig.3] schematically illustrates a motor vehicle comprising a thermal regulation circuit according to the invention in an embodiment comprising, in the first loop, an intermediate component controlled by a proportional three-way valve, and an additional component at the level of the inlet pipe, and in the second loop, a non-return valve on a bypass between an inlet junction and an outlet junction.

[0038] The invention relates to a motor vehicle 1000 comprising a thermal regulation circuit 100, forming a device for distributing heat transfer fluid in several loops, without a distribution valve between these loops.

[0039] [Fig.2] illustrates a motor vehicle 1000 comprising a regulation circuit thermal valve 100 according to the invention, which differs mainly from the prior art illustrated in [Fig.l] by the elimination of the second proportional three-way valve 5.

[0040] This motor vehicle 1000 comprises control means 800 which are arranged to control at least one thermal regulation circuit 100 comprising a heat transfer fluid circulating in at least a first loop 10 and a second loop 20. The thermal regulation circuit comprises at least two thermodynamic loops, the examples are described here with only a first loop 10 and a second loop 20 for the purposes of simplification, but the principle can be generalized to more loops.

[0041] The first loop 10 comprises, from a first inlet 101 and a first inlet junction 16, a first main pipe 19 passing through a first thermodynamic component 1 and a first circulation pump 7 to a first outlet junction 18, upstream of a first outlet 102, which is arranged to cooperate with a second inlet 201 which the second loop 20 comprises.

[0042] The second loop 20 comprises, downstream of this second inlet 201 and a second inlet junction 26, a second main pipe 29 passing through a second circulation pump 8 and a second thermodynamic component 3 to a second outlet junction 28, upstream of a second outlet 202 which is arranged to cooperate with the first inlet 101 of the first loop 10.

[0043] More particularly, the control means 800 are arranged to control the value and the distribution of the flow rates of the heat transfer fluid in the first loop 10 and in the second loop 20 by controlling the first circulation pump 7 and the second circulation pump 8, with reference to at least one control table 500 that the control means 800 comprise and which comprises instructions for adjusting the speed of the first circulation pump 7 and the second circulation pump 8 suitable for obtaining a first flow rate in the first loop 10 and a second flow rate in the second loop 20.

[0044] Naturally, each control table 500 can be of a computer nature, and supported by a memory cooperating with a computer comprising the control means 800.

[0045] The invention thus consists of controlling the circulation pump 8 and the circulation pump 7, to choose the flow rate of heat transfer fluid in the first loop 10 and in the second loop 20, on the basis of one or more control tables 500, according to the external and / or internal thermal constraints.

[0046] More particularly, these control means 800 are arranged to control the value and the distribution of the flow rates of the heat transfer fluid in the first loop 10 and in the second loop 20 by controlling the first circulation pump 7 and the second circulation pump 8, according to information supplied to the control means 800 by temperature sensors 700 included in these control means 800 or the thermal regulation circuit 100.

[0047] More particularly, the first loop 10 comprises, downstream of the first inlet 101 and a first inlet pipe 14 entering a first inlet junction 16, the first main pipe 19 passing through the first thermodynamic component 1 and the first circulation pump 7 to a first outlet junction 18 upstream of a first outlet pipe 15 leading to the first outlet 102 of the first loop 10.

[0048] More particularly, the second loop 20 comprises, downstream of the second inlet 201 and a second inlet pipe 24 entering a second inlet junction 26, the second main pipe 29 passing through the second circulation pump 8 and the second thermodynamic component 3 to a second outlet junction 28 upstream of a second outlet pipe 25 leading to the second outlet 202 of the second loop 20.

[0049] More particularly, the control means 800 are arranged to control the value and the distribution of the flow rates of the heat transfer fluid in the first loop 10 and in the second loop 20 by controlling the first circulation pump 7 and the second circulation pump 8, as a function of information supplied to the control means 800 by temperature sensors 700 that the control means 800 comprise or that the thermal regulation circuit 100 comprises. These temperature sensors 700 can be either external, to choose an applicable control table, for example for a temperate climate, for a cold climate, for a hot climate (to be defined), or / and internal to automatically control the distribution of the flow rates as a function of the measured instantaneous temperatures, to regulate the flow of heat transfer fluid with reference to extreme setpoint values.

[0050] In particular, at least the first loop 10 and / or the second loop 20 respectively comprise a first branch pipe 17 downstream of the first outlet junction 18 joining the first main pipe 19 at the first inlet junction 16 and / or respectively a second branch pipe 27 downstream of the second outlet junction 28 joining the second main pipe 29 at the second inlet junction 26.

[0051] More particularly, the first loop 10 comprises a first bypass pipe 17 downstream of the first outlet junction 18 joining the first main pipe 19 at the first inlet junction 16, and / or the second loop 20 comprises a second bypass pipe 27 downstream of the second outlet junction 28 joining the second main pipe 29 at the second input junction 26.

[0052] More particularly, only one of the first loop 10 or the second loop 20 comprises, at its outlet junction 18, 28, downstream of its main pipe 19, 29, a proportional three-way valve 6, 5, one outlet of which corresponds to the outlet 102, 202 of the loop 10, 20, and the other outlet of which feeds a bypass pipe 17, 27, directly or indirectly joining its thermodynamic component 1, 3, or an inlet junction 16, 26 of the loop 10, 20.

[0053] More particularly, the first loop 10 comprises a first bypass pipe 17 which passes through an intermediate thermodynamic component 2 upstream of the first inlet junction 16 which is located between on the one hand the first inlet pipe 14 of the first loop 10 downstream of the first inlet 101, and on the other hand the first main pipe 19 passing through the first circulation pump 7 and the first thermodynamic component 1.

[0054] More particularly, the first outlet junction 18 of the first loop 10 comprises a first proportional three-way valve 6, a first outlet channel of which is the first bypass pipe 17 supplying the first additional thermodynamic component 2 upstream of the first inlet junction 16, and a second outlet channel of which is the first outlet pipe 15 of the first loop 10.

[0055] More particularly, the proportional three-way valve 6 is the only proportional three-way valve included in the thermal regulation circuit 100.

[0056] More particularly, the second loop 200 comprises a second bypass pipe 27 which passes through a non-return valve 9 upstream of the second inlet junction 26 which is located between on the one hand the second inlet pipe 24 of the second loop 20 downstream of the second inlet 201, and on the other hand the second main pipe 29 passing through the second circulation pump 8 and the second thermodynamic component 3.

[0057] More particularly, the first inlet pipe 14 of the first loop 10 passes through an additional thermodynamic component 4 upstream of the first inlet junction 16.

[0058] [Fig-3] illustrates a complete execution comprising, in the first loop 10 a first intermediate component 2 controlled by a proportional three-way valve 6 supplying a first bypass 17, and an additional component 4 at the level of the first inlet pipe 14, and in the second loop 20 a non-return valve 9 on a second bypass 27 between a second inlet junction 26 and a second outlet junction 28.

[0059] This [Fig.3] groups together the usual components visible in an automobile thermal regulation circuit. Naturally, the invention applies in a similar way to less complete circuits, lacking some of the components mentioned above.

[0060] The following example concerns this variant according to [Fig.3].

[0061] The distribution of the first flow rate Q1 between the first downstream flow rate Q4 passing through the first intermediate thermodynamic component 4, and the second downstream flow rate Q9 passing through the non-return valve 9, is carried out as a function of the rotation speed of the first circulation pump 7 and that of the second circulation pump 8. The first flow rate Q1 is equal to the sum of the first downstream flow rate Q4 and the second downstream flow rate Q9.

[0062] The respective rotation speeds of the first circulation pump 7 and the second circulation pump 8 have a direct influence on the first downstream flow rate Q4 passing through the first intermediate thermodynamic component 4, and the second downstream flow rate Q9 passing through the non-return valve 9.

[0063] For example, if the second circulation pump 8 is running at 100%, reducing the speed of the first circulation pump 7 will have the effect of increasing the second downstream flow rate Q9 and reducing the first downstream flow rate Q4. In the extreme, the first downstream flow rate Q4 can be completely zero.

[0064] Conversely, if the first circulation pump 7 is running at 100% and the speed of the second circulation pump 8 is varied, the second downstream flow rate Q9 can decrease to zero flow rate, and the first downstream flow rate Q4 will increase accordingly.

[0065] A default 500 control table, well suited to the use of a motor vehicle in a temperate climate, includes for example the following parameters, corresponding to significant intermediate values, according to eight non-limiting distributions.

[0066] First distribution: - Rotation speed of the first circulation pump 7 (%): 100 - Rotation speed of the second circulation pump pump 8 (%): 100 - First flow rate Q1 (1 / min): 18.9 - First downstream flow rate Q4 (1 / min): 2.6 - Second downstream flow rate Q9 (1 / min): 16.3

[0067] Second distribution: - Rotation speed of the first circulation pump 7 (%): 100 - Rotation speed of the second circulation pump pump 8 (%): 75 - First flow rate Q1 (1 / min): 17.2 - First downstream flow rate Q4 (1 / min): 1.3 - Second downstream flow rate Q9 (1 / min): 15.9

[0068] Third distribution: - Rotation speed of the first circulation pump 7 (%): 100 - Rotation speed of the second circulation pump pump 8 (%): 40 - First flow rate Q1 (1 / min): 12.3 - First downstream flow rate Q4 (1 / min): 0.5 - Second downstream flow rate Q9 (1 / min): 11.8

[0069] Fourth distribution: - Rotation speed of the first circulation pump 7 (%): 100 - Rotation speed of the second circulation pump pump 8 (%): 0 - First flow rate Q1 (1 / min): 11.5 - First downstream flow Q4 (1 / min): 0 - Second downstream flow Q9 (1 / min): 11.5

[0070] Fifth distribution: - Rotation speed of the first circulation pump 7 (%): 75 - Rotation speed of the second circulation pump pump 8 (%): 100 - First flow rate Q1 (1 / min): 16.9 - First downstream flow rate Q4 (1 / min): 0.2 - Second downstream flow rate Q9 (1 / min): 16.7

[0071] Sixth distribution: - Rotation speed of the first circulation pump 7 (%): 50 - Rotation speed of the second circulation pump pump 8 (%): 100 - First flow rate Q1 (1 / min): 16.8 - First downstream flow rate Q4 (1 / min): 6.2 - Second downstream flow rate Q9 (1 / min): 10.7

[0072] Seventh distribution: - Rotation speed of the first circulation pump 7 (%): 25 - Rotation speed of the second circulation pump pump 8 (%): 100 - First flow rate Q1 (1 / min): 16.6 - First downstream flow rate Q4 (1 / min): 11.2 - Second downstream flow rate Q9 (1 / min): 5.4

[0073] Eighth distribution: - Rotation speed of the first circulation pump 7 (%): 0 - Rotation speed of the second circulation pump pump 8 (%): 100 - First flow rate Q1 (1 / min): 16.3 - First downstream flow rate Q4 (1 / min): 16.3 - Second downstream flow Q9 (1 / min): 0

[0074] Such a control strategy is successfully applied to battery electric vehicles, or hybrid vehicles, with this type of control table 500 of the pumps and the resulting flow rates Q1, Q4 and Q9.

[0075] In this non-limiting example, the first circulation pump 7 has a power of 150 W, and the second circulation pump 8 has a power of 40 W.

[0076] Regardless of the pump controlled, it is possible to vary the flow distribution between Q4 and Q9.

[0077] However, the use of pumps of different power makes it possible to obtain different sensitivity.

[0078] Depending on the control of the second circulation pump 8, the sensitivity is quite fine, the second downstream flow rate Q9 varies from 0 to 2.6 1 / min.

[0079] On the other hand, for the use of the first circulation pump 7, the sensitivity is higher, the first downstream flow rate Q4 can vary from 0 up to 16.3 1 / min.

[0080] In summary, the motor vehicle comprises control means, in which at least one control table is loaded, and these control means control the speeds of the first circulation pump and the second circulation pump on the basis of a default control table, or a particular control table chosen by the user or by the control means of the vehicle as a function of the climatic conditions external and internal to the vehicle, in particular according to the indications provided by external and / or internal temperature sensors connected to these control means, in particular to check the temperature in each thermal loop.
