Description

TECHNICAL FIELD

[0001] The present invention relates to a cooling module for an electric or hybrid motor vehicle, having tangential flow turbines. BACKGROUND

[0002] The cooling module (or heat exchange module) of a motor vehicle generally comprises at least one heat exchanger and a ventilation device designed to generate an airflow in contact with the at least one heat exchanger. Thus, when the vehicle is stationary or traveling at low speed, the ventilation device makes it possible to generate an airflow in contact with the heat exchanger, for example.

[0003] In a motor vehicle having a conventional internal combustion engine, the at least one heat exchanger has a substantially square shape and the ventilation device is a bladed fan whose diameter is substantially equal to the length of a side of the square formed by the heat exchanger.

[0004] Generally, the heat exchanger is placed facing at least two cooling openings formed in the front face of the body of the motor vehicle. The first cooling opening is located above the bumper and the second cooling opening is located below the bumper. This configuration is preferred because the internal combustion engine must also be fed with air and the intake of the engine is generally located in the passage of the airflow through the upper cooling opening.

[0005] However, an electric vehicle is preferably provided with only a cooling opening located below the bumper, and even more preferably with only a single cooling opening located below the bumper.

[0006] This is because the electric motor does not require an air supply. In addition, the reduction in the number of cooling openings and their size makes it possible to improve the aerodynamic properties of the electric vehicle. This also leads to a better range and faster top speed of the motor vehicle. Thus, according to the manufacturer's requirements, for electric and hybrid vehicles, in particular to improve the lift-to-drag ratio, the height of the heat exchanger present in these cooling openings is reduced and its thickness is increased.

[0007] However, stacking the heat exchangers in the direction of the airflow through the heat exchangers means that each heat exchanger positioned upstream influences the performance of the exchangers placed downstream. SUMMARY

[0008] Thus, one of the objectives of the present invention is to at least partially eliminate the drawbacks of the prior art and to propose an improved cooling module which allows an optimal level of performance of the different heat exchangers.

[0009] Thus, the present invention relates to a cooling module for an electric or hybrid motor vehicle, designed to have an airflow pass therethrough, and comprising at least one heat exchanger connected within a cooling circuit and a vehicle dryer,

[0010] The vehicle dryer is positioned in an upstream portion of the cooling module when considered in a longitudinal direction extending from a front portion towards a rear portion of the cooling module, and the vehicle dryer is positioned downstream of and facing the deflection element in this longitudinal direction of the cooling module.

[0011] According to one aspect of the application, the at least one heat exchanger positioned most upstream in the longitudinal direction of the cooling module and the vehicle dryer are arranged in the same plane.

[0012] According to another aspect of the application, the vehicle dryer is positioned such that its axis is perpendicular to the height axis of the at least one heat exchanger.

[0013] According to another aspect of the application, the deflection element is a transverse member of a frame of a frontal shut-off device positioned upstream of the at least one heat exchanger.

[0014] According to another aspect of the application, the deflection element is a crossbeam of a chassis of the motor vehicle, positioned upstream of the at least one heat exchanger.

[0015] According to another aspect of the application, the cooling module comprises two heat exchangers positioned in the same plane at the most upstream position in the longitudinal direction of the cooling module, the vehicle dryer being positioned between the heat exchangers.

[0016] According to another aspect of the application, the cooling module comprises:

[0017] a first heat exchanger configured to be a condenser connected within a cooling circuit,

[0018] a second heat exchanger configured to be a low-temperature radiator connected within a thermal management circuit, and

[0019] a third heat exchanger configured to be an auxiliary cooler connected within the cooling circuit.

[0020] According to another aspect of the application, in a direction of circulation of the heat transfer fluid, the thermal management circuit comprises:

[0021] a pump,

[0022] a first cooler, and

[0023] a second heat exchanger.

[0024] According to another aspect of the application, in a direction of circulation of the refrigerant, the cooling circuit comprises:

[0025] a compressor,

[0026] a first heat exchanger,

[0027] Vehicle dryer,

[0028] Third heat exchanger,

[0029] First expansion device, and

[0030] Second cooler.

[0031] According to another aspect of the application, the cooling circuit comprises a bypass branch connected in parallel to the first expansion device and to the first cooler, said bypass branch comprising a second expansion device positioned upstream of the third cooler.

[0032] According to another aspect of the application, the second heat exchanger and the third heat exchanger are positioned in the same plane upstream of the first heat exchanger when considered in the longitudinal direction of said cooling module.

[0033] According to another aspect of the application, the cooling module comprises a fourth heat exchanger configured to be a low temperature radiator and positioned downstream of the first heat exchanger in the longitudinal direction of said cooling module. BRIEF DESCRIPTION OF DRAWINGS

[0042] The following examples are illustrative. Although the specification refers to one or more embodiments, this does not necessarily mean that each reference is to the same embodiment, or that features only apply to one embodiment. Individual aspects of the different embodiments can also each be provided independently of the other aspects or in any combination thereof.

[0043] In the present specification, certain elements or parameters can be indexed, for example a first element or a second element and a first parameter and a second parameter or a first criterion and a second criterion, etc. In this case, this is a simple index to distinguish and designate similar but non-identical elements or parameters or criteria. This index does not imply a higher priority of one element, parameter or criterion over another, and such designations can be easily interchanged without departing from the scope of the present specification. This index also does not imply a chronological order, for example in the evaluation of any given criterion.

[0044] In the present specification, "placed upstream" is understood to mean that, with respect to the direction of circulation of the airflow, one element is placed before another element. By contrast, "placed downstream" is understood to mean that, with respect to the direction of circulation of the airflow, one element is placed after another element.

[0045] In Figure 1 , 2 , 4, 5 and 6, a trihedron XYZ is shown to define the orientation of various elements relative to one another. A first direction, denoted by X, corresponds to the longitudinal direction of the vehicle. This first direction also corresponds to the direction opposite to that in which the vehicle moves forward. A second direction, denoted by Y, is the lateral or transverse direction. Finally, a third direction, denoted by Z, is the vertical direction. The directions X, Y, Z are pairwise orthogonal.

[0046] In the present specification, "lower (lower portion)" is understood to mean the position of one element relative to another element in the direction Z determined above.

[0047] In Figure 1 and Figure 2 , the cooling module according to the application is shown in a functional position, that is to say in the position in which it is arranged inside a motor vehicle.

[0048] Figure 1A front portion of an electric or hybrid motor vehicle 10 is schematically shown, which can comprise an electric motor 12. In particular, the vehicle 10 comprises a body 14 and a bumper 16 supported by a chassis (not shown) of the motor vehicle 10. The body 14 defines a cooling opening 18, i.e. an opening through the body 14. In this case, there is only one cooling opening 18. This cooling opening 18 is preferably located in a lower part of a front face 14a of the body 14. In the example shown, the cooling opening 18 is located below the bumper 16. A grille 20 can be positioned in the cooling opening 18 to prevent a projectile from being able to pass through the cooling opening 18. A cooling module 22 is positioned facing the cooling opening 18. The grille 20 in particular makes it possible to protect this cooling module 22.

[0049] As Figure 2 shown, the cooling module 22 is designed to have a flow of air F pass through it parallel to a direction X, from the front portion of the vehicle 10 to the rear portion. This direction X more particularly corresponds to a longitudinal direction X extending from a front portion of the cooling module 22 towards a rear portion. In this application, an element positioned more forward or more rearward than another element in the longitudinal direction X of the cooling module 22 is respectively called “upstream” or “downstream”. “Front” corresponds to a front portion of the motor vehicle 10 in the assembled state, or to a surface of the cooling module 22 through which the flow of air F is intended to enter the cooling module 22. “Rear” corresponds, for its part, to a rear portion of the motor vehicle 10, or to a surface of the cooling module 22 through which the flow of air F is intended to exit the cooling module 22.

[0050] The cooling module 22 comprises at least one heat exchanger 24, 26, 28, 29, as Figure 2 shown. More particularly, the at least one heat exchanger 24, 26, 28, 29 is positioned within a heat exchanger group 23. More particularly, this heat exchanger group 23 can comprise a first heat exchanger 24, a second heat exchanger 26 and a third heat exchanger 28.

[0051] The first heat exchanger 24 is in particular configured to dissipate thermal energy into the flow of air F. This first heat exchanger 24 can more particularly be a condenser of a cooling circuit A, as Figure 3 shown, making it possible to cool a battery of the vehicle 10. This cooling circuit A can also be configured to provide thermal management of a flow of air intended for the interior of the vehicle. In this case, the cooling circuit A can be an air conditioning circuit, in particular a reversible air conditioning circuit. The first heat exchanger 24 can thus be an evaporator-condenser in the context of a reversible air conditioning circuit (not shown).

[0052] The third heat exchanger 28 is itself configured to be an auxiliary cooler connected within the air conditioning circuit A. This third heat exchanger 28 is thus also configured to dissipate thermal energy into the flow of air F.

[0053] The second heat exchanger 26 is also configured to release thermal energy into the airflow F. This second heat exchanger 26 can more particularly be a radiator connected to the thermal management circuit C (visible in Figure 3 ) for electrical elements such as the electric motor 12.

[0054] In the example illustrated in Figure 2 , the heat exchanger group 23 comprises a fourth heat exchanger 29 which is also configured to release thermal energy into the airflow F. More particularly, this fourth heat exchanger 29 can also be a cryogenic radiator. As Figure 3 illustrated, the fourth heat exchanger 29 can be connected to the thermal management circuit C in parallel with the second heat exchanger 26. However, embodiments in which the fourth heat exchanger 29 is connected to another thermal management circuit (not shown) can be entirely envisaged, for example dedicated to the cooling of power electronics.

[0055] Again with reference to Figure 2 , the cooling module 22 essentially comprises a housing or fairing 40 forming an internal duct between two opposite ends 40a, 40b, and in which the heat exchanger group 23 is located. This internal duct is preferably oriented parallel to the longitudinal direction X, so that the upstream end 40a is oriented towards the front of the vehicle 10, facing the cooling opening 18, and so that the downstream end 40b is oriented towards the rear of the vehicle 10.

[0056] The cooling module 22 also comprises a plenum housing 41 positioned downstream of the heat exchanger group 23 in the longitudinal direction X of the cooling module 22. This first plenum housing 41 comprises an outlet 45 for the airflow F. This first plenum housing 41 thus makes it possible to recover the airflow passing through the heat exchanger group 23 and to direct it towards the outlet 45. The first plenum housing 41 can be integral with the fairing 40 or can be an additional part fixed on the downstream end 40b of said fairing 40.

[0057] The cooling module 22 also comprises at least one tangential fan, also called tangential flow turbine 30, configured to generate an airflow F towards the heat exchanger group 23. The tangential flow turbine 30 comprises a rotor or turbine (or tangential propeller) not shown. The turbine has a substantially cylindrical shape. The turbine advantageously comprises multiple stages of blades (or vanes). The turbine is mounted to rotate around an axis of rotation A, for example parallel to the direction Y. The diameter of the turbine is for example between 35 mm and 200 mm in order to limit its size. The turbine 30 is thus compact.

[0058] The tangential flow turbine 30 may also include a motor 31 configured to rotate the turbine. The motor 31 is, for example, designed to drive the turbine at speeds between 200 rpm and 14,000 rpm. This significantly reduces the noise generated by the tangential flow turbine 30.

[0059] The tangential flow turbine 30 is preferably positioned within the first gas collection casing 41. The tangential flow turbine 30 is then configured to draw in air to generate an airflow F that passes through the heat exchanger assembly 23. The first gas collection casing 41 then forms a volute, with the turbine 32 positioned at the center of the volute, and air at the outlet 45 of the first gas collection casing 41 is discharged from the volute, thereby allowing the airflow F to exit the volute.

[0060] exist Figure 2 In the example shown, the tangential flow turbine 30 is positioned high, particularly in the upper third of the first gas collection casing 41, preferably in the upper quarter of the first gas collection casing 41. This allows for protection of the tangential flow turbine 30 and / or limits the dimensions of the lower portion of the cooling module 22, especially in submerged conditions.

[0061] However, it is conceivable that the tangential flow turbine 30 is positioned low, particularly in the lower third of the first gas collection casing 41. This would allow for limiting the space occupied by the upper portion of the cooling module 22. Alternatively, the tangential flow turbine 30 could be positioned in the middle, particularly in the middle third of the height of the first gas collection casing 41, for example, for the purpose of integrating the cooling module 22 around it.

[0062] In addition, Figure 2 In the example shown, the tangential flow turbine 30 operates in an intake manner, meaning it draws in ambient air, which then passes through the heat exchanger assembly 23. Alternatively, the tangential flow turbine 30 can operate by blowing air toward the heat exchanger assembly 23. For this purpose, the tangential flow turbine 30 would be positioned upstream of the heat exchanger assembly 23.

[0063] The cooling module 22 may also include a second air intake housing 42 positioned upstream of the heat exchanger assembly 23. The second air intake housing 42 includes an inlet 42a for airflow F from outside the vehicle 10. The inlet 42a may be positioned, in particular, toward the cooling opening 18. The inlet 42a may also include a protective grille 20. The second air intake housing 42 may be integral with the fairing 40, or may be an attachment fastened to the upstream end 40a of the fairing 40.

[0064] Furthermore, the inlet 42a of the second gas collecting housing 42 may include a front shut-off device 421 (in Figure 5As can be seen in the image, the device is configured to allow airflow F from outside the vehicle 10 to pass through the first inlet 42a when the device is in the open state, and to close the first airflow inlet 42a when the device is in the closed state. The front shut-off device 421 can take various forms, for example, as a plurality of rotating baffles 421b mounted to pivot within the frame 421a between an open position and a closed position. The rotating baffles 421b can be flag-shaped baffles, but other types of baffles, such as butterfly baffles, are also conceivable.

[0065] Figure 3 A schematic diagram of cooling circuit A and thermal management circuit C is shown, with a first heat exchanger 24, a second heat exchanger 26 and a third heat exchanger 28 connected to these two circuits.

[0066] The heat transfer fluid is designed to flow within the thermal management loop C, indicated by the dashed line. Therefore, in the direction of heat transfer fluid flow, the thermal management loop C may include a pump 80, a first cooler 82, and a second heat exchanger 26. The first cooler 82 may, in particular, be a heat exchange interface, for example, located near electrical components such as an electric motor 12 and / or power electronic devices, thereby managing their temperature.

[0067] As mentioned above, in Figure 3 In the example shown, the thermal management loop C may also include a third heat exchanger 29. Here, the third heat exchanger 29 is connected to the thermal management loop C in parallel with the second heat exchanger 26.

[0068] exist Figure 3 In the diagram, cooling circuit A is represented by a solid line. Refrigerant is designed to flow within cooling circuit A. Cooling circuit A includes a compressor 60 and a first heat exchanger 24 in the direction of refrigerant flow. The first heat exchanger 24 is configured as a condenser and designed to allow airflow F to pass through it. Downstream of the first heat exchanger 24, cooling circuit A includes a third heat exchanger 28, which is configured as an auxiliary cooler. Downstream of the third heat exchanger 28, cooling circuit A includes a first expansion device 63 and a second cooler 64, specifically designed for battery thermal management. The second cooler 64 may be an evaporator for direct cooling of the battery, or... Figure 3 As shown, it can be a dual-fluid heat exchanger arranged on additional circuit B for indirect cooling of the battery.

[0069] The additional circuit B may specifically include a pump 70 in contact with the battery and a thermal management interface 72, such as a cold plate. The additional circuit B may also include a bypass B' for bypassing the fifth heat exchanger 67, which includes a valve 74 to, for example, provide uniformity of battery temperature.

[0070] The cooling circuit A can comprise a bypass branch A' connected in parallel with the first expansion device 63 and the first cooler 64. This bypass branch A' comprises a second expansion device 66 positioned upstream of a third cooler 67. This third cooler 67 can in particular be an evaporator intended to pass the air flow to the vehicle interior through it.

[0071] Between the first heat exchanger 24 and the third heat exchanger 28, the cooling circuit A comprises a vehicle dryer 61. This vehicle dryer 61 is in particular connected within the cooling circuit A between the first heat exchanger 24 and the third heat exchanger 28 and downstream of the first heat exchanger 24 in the circulation direction of the refrigerant circulating in the cooling circuit A.

[0072] As Figure 2 to Figure 4 indicated, the third heat exchanger 28 is positioned upstream most in the longitudinal direction X of the cooling module 22 within the heat exchanger group 23. This allows the cooling module 22 to benefit from the "coldest" air of the air flow F. Thus, the third heat exchanger 28 can effectively perform its function of supercooling the refrigerant circulating in the cooling circuit A. Thus, the coefficient of performance of the cooling circuit A is high and its cooling capacity is for example sufficient to simultaneously ensure the cooling of the air flow to the vehicle interior and the cooling of the battery.

[0073] Again as Figure 2 to Figure 4 indicated, the second heat exchanger 26 is positioned upstream of the first heat exchanger 24 within the heat exchanger group 23 along the longitudinal direction X of the cooling module 22 within the heat exchanger group 23. More particularly, the second heat exchanger 26 and the third heat exchanger 28 can be positioned in the same plane within the heat exchanger group 23 upstream of the first heat exchanger 24 along the longitudinal direction X of the cooling module 22. This allows the second heat exchanger 26 and the third heat exchanger 28 to both be located further upstream of the cooling module 22 along the longitudinal direction X. Thus, the second heat exchanger 26 and the third heat exchanger 28 both benefit from the "coldest" air in order to dissipate heat energy as efficiently as possible.

[0074] Preferably, the cumulative height of the second heat exchanger 26 and the third heat exchanger 28 is substantially equal to the height of the first heat exchanger 24. Thus, this makes it possible to maintain a similar size for each level or echelon of heat exchangers in the heat exchanger group 23. This also makes it possible to limit the number of heat exchangers through which the air flow F passes, thereby limiting the drop in head. Thus, for example, a fourth heat exchanger 29 can be added in the air flow F downstream of the first heat exchanger 24.

[0075] Still according to Figure 2 to Figure 4The third heat exchanger 28 is preferably positioned below the second heat exchanger 26. In this case, "positioned below" means that the third heat exchanger 28 is closer to the ground than the second heat exchanger 26 when installed within the motor vehicle 10.

[0076] As shown in Figure 4 , within the cooling module, the vehicle dryer 61 is positioned in an upstream portion of the cooling module 22 when considered in a longitudinal direction X extending from a front portion of said cooling module 22 towards a rear portion. More particularly, the vehicle dryer 61 is positioned downstream of and facing the deflection element 70 (visible in Figure 5 and 6 ). This positioning of the vehicle dryer 61 behind the deflection element 70 makes it possible to limit the disturbances caused by the vehicle dryer 61 to the air flow F. In particular, only the perturbations and turbulences caused by the deflection element 70 have an impact on the heat exchangers 24, 26, 28 and 29.

[0077] As shown in Figure 4 , the at least one heat exchanger 24, 26, 28, 29 positioned most upstream in the longitudinal direction X of said cooling module 22, in this case the second heat exchanger 26, and the vehicle dryer 61 can be arranged in the same plane. This makes it possible for the cooling module 22 to occupy significantly less space. More particularly, the vehicle dryer 61 can be positioned such that its axis, in this case the transverse axis Y, is perpendicular to the height axis Z of said at least one heat exchanger 24, 26, 28, 29. Thus, the vehicle dryer 61 "lies" below or above said at least one heat exchanger 24, 26, 28, 29.

[0078] In the case where the cooling module 22 comprises two heat exchangers, in this case the second heat exchanger 26 and the third heat exchanger 28 are positioned in the same plane and are positioned most upstream along the longitudinal direction X of said cooling module 22, the vehicle dryer 61 can more particularly be positioned between said heat exchangers 26, 28, as shown in Figure 4 to Figure 6 .

[0079] Preferably, the deflection element 70 is an element already present within the motor vehicle 10 or within the cooling module 22. Thus, by placing the vehicle dryer 61 behind this element, the turbulences or perturbations affecting the air flow F are not greater than those already present.

[0080] According to Figure 5In the first alternative form shown, the deflection element 70 can be a cross member of the frame 421a of the frontal shut-off device 421 positioned upstream of at least one of the heat exchangers 24, 26, 28, 29. The frontal shut-off device 421 here comprises a portion, called upper portion, facing the second heat exchanger 26 and a portion, called lower portion, facing the third heat exchanger 28. The vehicle dryer 61, which is positioned between the second heat exchanger 26 and the third heat exchanger 28, is thus hidden by the cross member of the frame 412a separating the two portions. The air flow F can thus flow in the two portions without being disturbed by the vehicle dryer 61.

[0081] According to Figure 6 In the second alternative form shown, the deflection element 70 can be a cross member of the chassis of the motor vehicle 10, positioned upstream of at least one of the heat exchangers 24, 26, 28, 29. As in the first alternative form, the cross member of the chassis of the motor vehicle 10 defines a portion, called upper portion, facing the second heat exchanger 26 and a portion, called lower portion, facing the third heat exchanger 28. The vehicle dryer 61, which is positioned between the second heat exchanger 26 and the third heat exchanger 28, is thus hidden by the cross member separating the two portions. The air flow F can thus flow in the two portions without being disturbed by the vehicle dryer 61.

[0082] It can thus be clearly seen that the provision of the vehicle dryer 61 downstream of the deflection element 70 and facing the deflection element 70 allows a better circulation of the air flow F, thus achieving optimal performance of the various heat exchangers, and allows the cooling module 22 to occupy a smaller space.
