• a cooling module (or heat exchange module) of a motor vehicle conventionally comprises at least one heat exchanger and a ventilation device adapted to generate an air flow in contact with the at least one heat exchanger.
• the ventilation device thus makes it possible, for example, to generate a flow of air in contact with the heat exchanger, when the vehicle is stationary or at low driving speed.
• the at least one heat exchanger is substantially square in shape, the ventilation device then being a propeller fan whose diameter is substantially equal to the side of the square formed by the heat exchanger.
• the heat exchanger is then placed opposite at least two cooling bays, formed in the front face of the motor vehicle body.
• a first cooling bay is located above the bumper while a second bay is located below the bumper.
• Cooling bays are usually protected by a grille.
• electric vehicles are preferably only provided with cooling bays located under the bumper, because the electric motor does not need to be supplied with air.
• the motor vehicle may be provided with a single cooling bay located under the bumper, or even not include any cooling bay at all.
• the object of the present invention is therefore to at least partially remedy the drawbacks of the prior art and to propose an improved cooling module making it possible to circulate an air flow through the exchanger(s) even in the absence of a grille and/or a cooling bay.

• Figure 2 shows a schematic representation in perspective and in partial section of the front of a motor vehicle and of a cooling module according to a first embodiment
• FIG 3 shows a schematic sectional representation of a cooling module according to a second embodiment
• FIG 4 shows a schematic sectional representation of a cooling module according to a third embodiment.
• first element or second element as well as first parameter and second parameter or even first criterion and second criterion, etc.
• it is a simple indexing to differentiate and name elements or parameters or criteria that are close, but not identical.
• This indexing does not imply a priority of one element, parameter or criterion over another and such denominations can easily be interchanged without departing from the scope of the present description.
• This indexing does not imply an order in time either, for example to assess such and such a criterion.
• FIG. 1 In figures 1 to 4 is represented an XYZ trihedron in order to define the orientation of the various elements from each other.
• a first direction denoted X
• a second direction denoted Y
• a third direction denoted Z
• the directions, X, Y, Z are orthogonal two by two.
• FIG. 1 schematically illustrates the front part of an electric or hybrid motor vehicle 10 which may include an electric or hybrid motor 12.
• the vehicle 10 comprises in particular a body 14 and a bumper 16 carried by a chassis (not shown) of the motor vehicle 10.
• a cooling module 22 is arranged below the bumper 16 and facing the underbody of the motor vehicle 10
• the front face 14a of the bodywork 14 can define a cooling bay 18, that is to say an opening through the bodywork 14.
• This cooling bay 18 is preferably located opposite the cooling module 22.
• a grille 20 can optionally protect this cooling module 22.
• the cooling module 22 is intended to be traversed by an air flow L substantially parallel to the direction X going from the front to the rear of the vehicle 10.
• the direction X corresponds more particularly to the longitudinal axis of the cooling module 22 and the air flow L circulates from an air inlet 22a to an air outlet 22b.
• an element is referred to as "upstream” or "downstream” according to the longitudinal direction X of the cooling module 22, an element which is respectively disposed further forward or rearward than another element.
• the front corresponds to the front of the motor vehicle 10 in the assembled state.
• the rear corresponds to the rear of the motor vehicle 10 or else to the face of the cooling module 22 through which the air flow L is intended to come out of the cooling module 22.
• upper and lower is meant an orientation in the direction Z.
• a so-called upper element will be closer to the roof of the vehicle 10 and a so-called lower element will be closer to the ground.
• the cooling module 22 essentially comprises a fairing 40 forming an internal duct between an upstream end 40a and a downstream end 40b opposite each other.
• This internal conduit is preferably oriented parallel to the direction X so that the upstream end 40a is oriented towards the front of the vehicle 10 and so that the downstream end 40b is oriented towards the rear of the vehicle 10.
• inside said fairing 40 is arranged at least one heat exchanger 24, 26, 28.
• the cooling module 22 comprises three heat exchangers 24, 26, 28 grouped together within a set of exchangers heat 23, it could however include more or less depending on the desired configuration.
• the fairing 40 comprises an opening 401 delimiting the downstream end 40b and at least one junction wall 410 delimiting the internal duct.
• the latter comprises an opening 200 at its upstream end 40a so as to delimit the latter.
• This opening 200 is in particular located opposite the grille 20 in the case where the latter is present on the front face 14a of the motor vehicle 10.
• the fairing 40 can comprise a front wall 400 which obstructs the upstream end 40a, there is therefore no opening 200 as in the mode of previous achievement.
• the front face 14a of the motor vehicle 10 in particular does not have a grille 20 and the aerodynamics of the motor vehicle 10 can thus be optimized.
• the at least one junction wall 410 of the fairing 40 further comprises at least one suction opening 01, 02, 03 forming an air inlet 22a which allows air to penetrate inside the cooling module 22 .
• At least one so-called main suction opening 01 is arranged upstream of at least one heat exchanger 24, 26, 28 so that the air penetrating through this main suction opening 01 passes through the set 23 of heat exchangers heat exchangers 24, 26, 28.
• the cooling module 22 comprises at least two heat exchangers 24, 26, 28 arranged in the internal duct in the longitudinal direction X.
• the at least one main suction opening 01 is then arranged upstream of the heat exchanger 28 juxtaposed at the upstream end 40a.
• the at least one junction wall 410 includes at least one so-called secondary suction opening 02, 03 arranged between two adjacent heat exchangers 24, 26, 28, as illustrated in particular in the figures. 2 and 3.
• a first secondary opening 02 can be placed between the heat exchangers 28 and 24 and a second secondary opening 03 can be placed between the heat exchangers between 24 and 26.
• Such a secondary suction opening 02, 03 arranged between two heat exchangers 24, 26, 28 neighbors can bring cooler air to the heat exchanger disposed downstream of the latter, which can optimize its heat exchange.
• a first heat exchanger 24 can for example be configured to release heat energy from the air flow F.
• This first heat exchanger 24 can more particularly be a condenser connected to a cooling circuit (not shown), for example in order to cool the batteries of the vehicle 10.
• This cooling circuit can for example be an air conditioning circuit able to cool the batteries as well as an internal air flow intended for the passenger compartment of the motor vehicle.
• a second heat exchanger 26 can also be configured to release heat energy into the air flow F.
• This second heat exchanger 26 can more particularly be a radiator connected to a thermal management circuit (not shown) of electrical elements such as the electric motor 12.
• the first heat exchanger 24 generally being a condenser of an air conditioning circuit, the latter needs the air flow F to be as "cool" as possible in air conditioning mode
• the second heat exchanger 26 is preferably arranged downstream of the first heat exchanger 24 in the direction of circulation of the air flow F. It is nevertheless quite possible to imagine that the second heat exchanger 26 is arranged upstream of the first heat exchanger 24.
• the third heat exchanger 28 can also be configured to release heat energy into the airflow.
• This third heat exchanger 28 may more particularly be a radiator connected to a thermal management circuit (not shown), which may be separate from that connected to the second heat exchanger 26, for electrical elements such as power electronics. It is also quite possible to imagine that the second 26 and the third 28 heat exchanger are connected to the same thermal management circuit, for example connected in parallel with each other.
• the second heat exchanger 26 is arranged downstream of the first heat exchanger 24 while the third heat exchanger 28 is arranged upstream of the first heat exchanger 24.
• Other configurations can nevertheless be envisaged, such as for example the second 26 and third 28 heat exchangers both arranged downstream or upstream of the first heat exchanger 24.
• each of the heat exchangers 24, 26, 28 has a generally parallelepipedal shape determined by a length, a thickness and a height.
• the length extends along the Y direction, the thickness along the X direction and the height in the Z direction.
• the heat exchangers 24, 26, 28 then extend along a generally parallel plane in the vertical direction Z and the lateral direction Y. This general plane is thus perpendicular to the longitudinal direction X of the cooling module 22, the heat exchangers 24, 26, 28 are therefore perpendicular to the flow of air F intended to pass through them .
• the fairing 40 forming the internal duct is complementary to the general parallelepiped shape of at least one heat exchanger 24, 26, 28.
• the fairing 40 thus comprises four junction walls 410 including an upper wall 411 and a lower wall 412 arranged facing each other as well as two side walls (not visible in the figures) which connect the upper wall 411 to the lower wall 412.
• the upper wall 411 and the lower wall 412 extend in particular in a plane substantially parallel to the plane generated by the axes X and Y while the two side walls extend in a plane substantially parallel to the plane generated by the axes X and Z.
• the internal duct has in this particular case a rectangular or square section.
• the internal duct may have a section of shape different from that of a quadrilateral.
• the section of the internal duct can in particular take the form of a hexagon (in this case the fairing 40 comprises six junction walls 410), of an octagon (in this case the fairing 40 comprises eight junction walls 410) or even a circular shape (in this case the fairing 40 is cylindrical in shape and has a single junction wall 410 which forms the mantle of the cylinder).
• the section of the internal duct depends mainly on the geometry of at least one heat exchanger 24, 26, 28 arranged in this internal duct, inside the fairing 40.
• the at least one suction opening 01, 02, 03 perforates a lower part of the fairing 40 of the cooling module 22, for example the lower wall 412 In this case, it is the air present at the level of the underbody of the vehicle which enters the cooling module 22 via the at least one suction opening 01, 02, 03 to form the air flow F intended to circulate through the at least one heat exchanger 24, 26, 28 before being discharged through the air outlet 22b.
• the at least one suction opening 01, 02, 03 forming the air inlet 22a perforates an upper part of the fairing 40, for example the wall upper 411.
• the body 14 defines a cooling bay 18, that is to say an opening through the body 14 to allow air to pass close to the body 14 up to the at least one opening suction 01, 02, 03.
• only a main suction opening 01 is shown on the upper part of the fairing 40.
• at least one secondary suction opening arranged on this upper part of the fairing 40 is quite possible to imagine an embodiment also with at least one secondary suction opening arranged on this upper part of the fairing 40.
• the cooling module 22 may comprise at least one closure device 42 movable between an open position and a closed position of said at least one suction opening 01, 02, 03.
• the at least one device closure 42 may in particular comprise at least one pivoting flap 420 configured to pivot about a pivot axis A42 (visible in Figure 3) and intended to close the at least one suction opening 01, 02, 03. It there may in particular be a pivoting flap 420 per suction opening 01, 02, 03.
• the pivoting flap or flaps 420 may be butterfly flaps or flag flaps.
• the cooling module 22 can include a control unit (not shown in the figures) configured to control the shutter device 42.
• the control unit can be configured to position and immobilize the shutter device 42 in at least one intermediate position during movement of said closure device 42 between its open position and its closed position.
• the angle of inclination of the pivoting flaps 420 makes it possible to regulate the flow of air F penetrating inside the cooling module 22 via the air inlet 22a formed by the suction opening or openings 01, 02, 03 within the junction walls 410 of the fairing 40.
• the flow of air F circulating through the heat exchanger(s) 24, 26, 28 can be adjusted according to the performance required from said exchangers heat 24, 26, 28.
• control unit can be configured to control each pivoting flap 420 independently.
• F 'one can thus imagine configurations where one or more pivoting flaps 420 obstruct the suction opening 01, 02, 03 to which they are attached while other pivoting flaps 420 adopt an open position or a position intermediary, thus influencing the quantity of air passing through the suction opening or openings 01, 02, 03.
• FIG. 3 Such a configuration is particularly illustrated in FIG. 3 in which the pivoting flap 420 located upstream of the third heat exchanger 28 is represented in its open position, the pivoting flap 420 located upstream of the first heat exchanger 24 is shown in its intermediate position and the pivoting flap 420 located upstream of the second heat exchanger 26 is shown in its closed position.
• Fes edges of the at least one suction opening 01, 02, 03 intended to come into contact with the edge or edges of the closure device 42 may comprise one or more seals. Fe or the seals can make it possible to absorb the shock of the impact of the edges of the obturation device 42 on the edge(s) of the at least one suction opening 01, 02, 03 when the obturation device 42 begins its closed position. This or these joints seals can be made by overmolding the edge(s) of the at least one suction opening 01, 02, 03. Alternatively, the seal(s) can be inserts. Furthermore, the edge(s) of the closure device 42 may also include at least one seal. This at least one seal can be made by overmolding or it can be an added piece.
• the cooling module 22 also comprises a collector box 41 disposed downstream of the shroud 40 and of the assembly 23 of heat exchangers 24, 26, 28. More specifically, the collector box 41 is juxtaposed at the downstream end 40b of the fairing 40, it is therefore aligned with the fairing 40 along the longitudinal axis X of the cooling module 22.
• This collector box 41 comprises the air outlet 22b intended to discharge the air flow F.
• the collector box 41 thus allows to recover the air flow F passing through the set of heat exchangers 23 and to direct this air flow F towards the air outlet 22b, this is illustrated in particular by the arrows representing the air flow F in FIGS. 3 and 4.
• Collector box 41 may be integral with fairing 40 or else be an attached part fixed to the downstream end 40b of said fairing 40.
• Tangential turbomachine 30 includes a rotor or turbine 32 (also called tangential propeller).
• the turbine 32 has a substantially cylindrical shape.
• the turbine 32 advantageously comprises several stages of blades (or vanes), visible in FIG. 3.
• the turbine 32 is rotatably mounted around an axis of rotation A which is for example parallel to the direction Y.
• the diameter of the turbine 32 is for example between 35 mm and 200 mm to limit its size.
• the tangential turbomachine 30 is thus compact.
• the tangential turbomachine 30 can also comprise a motor 31 (visible in FIG. 2) configured to set the turbine 32 in rotation.
• the motor 31 is for example adapted to drive the turbine 32 in rotation, at a speed of between 200 rpm and 14000 rpm. This makes it possible in particular to limit the noise generated by the tangential turbomachine 30.
• the tangential turbomachine 30 is arranged in the manifold housing 4L
• the tangential turbomachine 30 is then configured to suck in air in order to generate the air flow F passing through the set of heat exchangers 23.
• the tangential turbomachine 30 comprises more specifically a volute 44, formed by the manifold housing 41 and at the center of which is arranged the turbine 32.
• the volute 44 at least partially delimits the air outlet 22b of the air flow.
• the air outlet of the volute 44 corresponds to the air outlet 22b of the air flow F of the collector box 4L
• the tangential turbomachine 30 is in a high position, in particular in the upper third of the manifold housing 41, preferably in the upper quarter of the manifold housing 41. This allows in particular to protect the tangential turbomachine 30 in the event of submersion and/or to limit the size of the cooling module 22 in its lower part.
• the air outlet 22b of the air flow F is preferably oriented towards the lower part of the cooling module 22.
• the tangential turbomachine 30 is in a low position, in particular in the lower third of the manifold housing 41. This would limit the size of the cooling module 22 in its upper part.
• the air outlet 22b of the air flow F will preferably be oriented towards the upper part of the cooling module 22.
• the tangential turbomachine 30 can be in a middle position, in particular in the middle third of the height of the first collector box 41, for example for reasons of integration of the cooling module 22 in its environment.
