    FR 3 063 338 - A1 (PT) The invention relates to a device for regulating (12) an air flow (F) circulating within a first heat exchanger (4) for a motor vehicle comprising at least two curtains (14), the regulating device (12) being configured to pass from a closed configuration where the curtains (14) completely block the passage of the air flow (F) to an open configuration where the curtains (14) are positioned so as to allow the air flow (F) to pass with maximum flow and any intermediate configuration.

    i
    The present invention relates to a device for regulating a flow of air circulating within a first heat exchanger for a motor vehicle as well as a cooling module provided with such a device.
    In this field, cooling modules are typically known comprising typically two heat exchangers, a first exchanger having the function of cooling an auxiliary circuit of the vehicle, such as an air conditioning device or a charge air cooling device, by means of a loop, called low temperature, and a second heat exchanger, necessary for the cooling of the vehicle engine. They are arranged on the front of the vehicle to be traversed by a flow of air entering through the grille of the vehicle. They include a heat exchange beam traversed by the fluid to be cooled and traversed by the air coming from the grille.
    To form a compact module, the two exchangers are assembled and aligned in series one after the other so that an air flow circulates successively in the two exchangers. The module is arranged in the vehicle so that the air circulates first in the first exchanger and then in the second heat exchanger, due to the cooling needs of each.
    However, this type of module does not allow the cooling of the two exchangers to be dissociated. This is a drawback because, in certain situations, it may be desirable to avoid cooling the engine so that it heats up more quickly, in particular when it is started.
    At the same time, the air circulation within the module is penalizing for the aerodynamics of the vehicle. In fact, the air that rushes under the hood of the vehicle into the cooling module inside the vehicle provides additional resistance to the movement of the vehicle. It is therefore all the more damaging to let the air pass through the entire module when there is no need for cooling at the level of the second exchanger, while ensuring the use of air conditioning or the cooling of the charge air.
    Known solutions, such as for example in document US 2015 246 608, propose cooling devices with a roll-down flap arranged vertically between two heat exchangers. A more or less significant winding of the curtain is provided, thereby regulating the air flow. In the majority of cases the opening of the entire surface of the exchangers is not necessary for cooling needs, the components being dimensioned for critical conditions. In addition, inadvertent opening and closing of the curtain parallel to the tubes can cause thermal shock at the exchangers. These thermal shocks impact the tubes by varying their length, îo This creates differential expansions at the feet of tubes attached to the manifolds causing leaks. The risk of leaks is increased during partial openings positioned in a non-uniform manner.
    There is therefore an advantage in designing a system of adaptable partial openings in order to optimize aerodynamic gains with regard to thermal needs.
    The invention therefore aims to overcome these drawbacks and for this purpose proposes a device for regulating an air flow circulating within a first heat exchanger for a motor vehicle, the regulating device comprising at least two curtains, the regulating device being configured to pass from a closed configuration where the curtains completely block the passage of the air flow to an open configuration where the curtains are positioned so as to allow the air flow to pass with a maximum flow rate, characterized in that the two curtains are arranged to move away from one another when the regulating device changes from the closed configuration to the open configuration and to approach each other when the regulating device changes from open configuration to closed configuration.
    By moving away from each other, for example from a central position, the flaps therefore guarantee by opening that the air flow is directed towards the central part of the heat exchangers thus reducing thermal shocks and differential expansions at the feet of the tubes.
    Other embodiments propose that:
    - the curtains are arranged to occupy one or more intermediate positions between the closed configuration and the open configuration;
    - the curtains are arranged in a frame capable of preventing any contact between one of said curtains and a heat exchanger;
    - the curtains include a sealing lip at one end, in particular the end facing the other curtain;
    - a closing element is arranged between the two curtains and on which the curtains come to rest by finishing their stroke in the closed configuration;
    - The closing element comprises a cylindrical rod with notches in particular of shape complementary to the sealing lips;
    - A first curtain has a sealing lip with a rib and the second curtain has a sealing lip with a groove of shape complementary to the rib;
    - the curtains are configured to be set in motion by an actuator, the actuator being a motor coupled to the closure element, said closure element being connected to each curtain by means of at least one wire connection;
    - the curtains are configured to be set in motion by an actuator, the actuator being a motor coupled to a pinion by means of a belt, said belt being connected to each curtain by means of at least one wire connection ;
    - the curtains are configured to be set in motion by an actuator, the actuator being a motor coupled to a worm screw, the worm screw being connected to each curtain by means of at least one wired connection,
    - the curtains are arranged to be set in motion simultaneously,
    - as a variant, the curtains are arranged to be set in motion independently, for example, one begins to move while the other is still at rest or one stops moving while the other is always on the go,
    the regulating device comprises a spring, in particular a torsion spring, arranged to keep the curtain or curtains stretched permanently,
    - the curtains are arranged to be movable perpendicular to the tubes of the exchangers,
    - discharge flaps can be added, which ensure the air flow on the first exchanger when there is no need for cooling on the high temperature heat exchanger, the retractable curtains remaining closed,
    - the regulating device comprises a frame of retractable curtains, io which frame is located in front of the high temperature heat exchanger,
    - the chassis also makes it possible to guarantee the seal between the two radiators or heat exchangers, and the regulation device,
    - the axes of the retractable curtains are fixed on the chassis,
    - the curtains are arranged to be actuable separately thanks to a pulley mechanism, in particular associated with two independent actuators.
    The invention also relates to a cooling module comprising
    - a low temperature heat exchanger,
    - a high temperature heat exchanger, and
    - A regulation device as described above arranged between the two exchangers, the low temperature heat exchanger being positioned upstream of the regulation device and the high temperature heat exchanger being positioned downstream of the regulation device.
    Other characteristics and advantages of the invention will become apparent on reading the description which is given for information only and which is not intended to limit it, and which follows from exemplary embodiments given at Illustrative title with reference to the appended figures.

    FIG. 1 illustrates a device 12 for regulating an air flow F as well as a cooling module 1 in accordance with the invention, in particular for a motor vehicle, according to a top view. The cooling module 1 comprises an upstream heat exchanger 2 and a downstream heat exchanger 4 arranged in series according to the direction of flow of an air flow F passing through them. In other words, the cooling module 1 is configured to be placed on a support, such as the chassis of a vehicle, so that the upstream heat exchanger 2 is traversed by an air flow F first and the downstream heat exchanger 4 second.
    In Figure 1, the upstream heat exchanger 2 is in the foreground and the downstream heat exchanger 4 is in a plane behind. Here, the upstream heat exchanger 2 is a cooling radiator, called low temperature, used to cool a coolant of a heat exchange loop, called low temperature, comprising, in particular, an air conditioning condenser and / or a charge air cooler. The downstream heat exchanger 4 is a high temperature cooling radiator intended to cool a coolant in a heat exchange loop comprising a vehicle engine. The air passing through this downstream exchanger 4 cools the engine coolant.
    Each exchanger 2, 4 comprises, for example, a heat exchange bundle 6 and collection chambers 8 disposed laterally on either side of the bundle 6. The bundle 6 is crossed by the air flow F. II comprises a set of tubes parallel to each other, opening into the collection chambers 8, for the circulation of the coolant.
    The cooling module 1 is configured to allow a substantially airtight flow of air between said heat exchangers 2,4, that is to say that the upstream heat exchanger 2 and the downstream heat exchanger 4 are assembled one to the other so that the downstream heat exchanger 4 is not directly traversed by air coming from outside the module. In other words, the air flow F passing through the downstream heat exchanger 4 comes from the air flow F passing through the upstream heat exchanger 2. For this, the cooling module 1 can for example comprise means d sealing allowing the entire air flow having passed through the upstream heat exchanger 2 to the downstream heat exchanger 4 without loss of air flow. These sealing means, not illustrated, may for example comprise a sheath arranged between the two upstream heat exchangers 2,4. Another alternative is to add 2,4 heat exchangers to each other.
    To facilitate the passage of an air flow in the cooling module 1, in particular when the vehicle is stationary, the module comprises a fan unit 10 capable of circulating the air in the cooling module 1. As illustrated in FIG. 1, the motor-fan group 10 is arranged downstream of the downstream heat exchanger 4, the motor-fan group 10 being configured to draw air from an air intake of the vehicle, which is preference defined by its grille.
    The cooling module 1 according to the invention further comprises a device 12 for regulating the air flow arranged between the upstream heat exchanger 2 and the downstream heat exchanger 4. The regulating device 12 controls the passage of the flow of air F from the upstream heat exchanger 2 to the downstream heat exchanger 4 by means of retractable curtains 14, or in other words sliding shutters or even unwinding films. To this end, the curtains 14 can pass from a closed or shutter configuration where they completely block the passage of the air flow F to an open or opening configuration where they free the passage of the air flow as much as possible. F. In other words, the curtains 14 do not obstruct the flow of the air flow F, or in other words, the curtains 14 are positioned so as to let the air flow F pass with a flow d maximum air. The curtains 14 can obviously adopt any intermediate position. The curtains are for example made of glass fibers, in particular glass fibers impregnated with PTFE.
    FIG. 2 illustrates a more detailed schematic view of the regulating device 12 according to the invention according to a front view. The regulating device 12 îo comprises two curtains 14 each winding or unwinding around a support 16 to pass from the open configuration to the closed configuration. The supports 16 are adapted to allow the winding or unwinding of the curtains 14. They can for example be in the form of a roll, that is to say a straight circular cylinder (or cylinder of revolution with bases being delimited by two equal and parallel circles) as illustrated in FIG. 2. In order to allow the movement of the curtains 14, the regulating device 12 comprises a motor or actuator 18. The curtains 14 may also include at their ends a sealing lip 20 .
    In order to guarantee good sealing of the assembly, the regulating device may include a closing element 22, which corresponds to an element on which the curtains 14 come to rest at the end of the travel in the closed configuration, namely when they are unrolled.
    FIGS. 2A to 2D illustrate different embodiments for this closing element 22. The closing element 22 can for example be a simple cylindrical rod as illustrated in FIG. 2A and 2B, where the flaps passing from an intermediate configuration (fig. 2A) in the closed configuration (fig. 2B) end their travel by pressing on the closing element as illustrated in figure 2B.
    The closing element 22 can have other shapes such as for example a rod with notches 24 of complementary shape to the sealing lips 20 (FIG. 2C, 2D). The invention is not limited either to the shape of the sealing lips 20 or to the shape of the notches.
    In the open configuration, the curtains 14 do not obstruct the flow of the air flow F. For this, the curtains 14 are entirely wound on the supports 16. It is possible to arrange the curtains 14 on the external surface a support 16 of cylindrical shape. However, in such a configuration the curtains
    14 are more exposed to external air thus resulting in premature wear and deterioration of the curtains 14. To remedy this wear, a hollow tube 30 can be arranged around the support 16, the hollow tube 30 comprises an opening 36 suitable for leaving pass the curtain 14 as illustrated in figure 3.
    îo In order to clean the curtain 14 and to avoid its premature deterioration as well as to guarantee an optimal winding around the support 16, the hollow tube 30 can present on its surface one or more tongues 56 arranged so as to rub the surface of the curtain 14 and remove any dirt or dust. The tab or tabs can be arranged on the external surface of the hollow tube 30 as illustrated in FIG. 3 or on the internal surface of the hollow tube 30.
    In order to ensure good maintenance and movement of the curtains 14, each curtain 14 can be welded to a support 16, or each curtain 14 can also include an end with a retention element 32, for example a plastic rod, suitable for s 'introduce into a notch 34, of complementary shape to the retention element 32, present on the support 16. A return spring 38 can also be arranged in the center of the support 16 so as to facilitate the movement of the curtains 14 and to keep the curtains 14 stretched. The return spring 38 is arranged so that it is prestressed when the curtains 14 are in the closed configuration, in other words entirely unwound around the support 16, and stretched when the curtains 14 are in the open configuration, that is to say - say rolled up.
    In order to make the least possible obstacle to the flow of the air flow F, the supports 16 and, if necessary, the hollow tubes 30 should be arranged near the collection chambers 8 of the heat exchangers 2 , 4 as illustrated in FIG. 1. It is understood by this that the supports 16 are arranged so that the collection chambers 8 of the heat exchangers 2,4 and the supports 16 are aligned in a longitudinal axis.
    In order to avoid deterioration of the films, the regulating device 12 may further comprise a hermetic frame 40, comprising bars or a grid with a grid, so as to allow the flow of air flowing while preventing the curtain. 14 to come into abutment against the heat exchangers 2,4. As illustrated in FIG. 1, the regulating device 12 comprises a hermetic frame 40 with a grid arranged between the regulating device 12 and the downstream heat exchanger 4 at high temperature, the heat being able to deteriorate the curtains 14. Good obviously, it is possible to design a regulation device 12 comprising two grids arranged on either side of the regulation device 12, or more precisely, a first grid positioned between the upstream heat exchanger 2 and the regulation device 12 and a second grid arranged between the downstream heat exchanger 4 and the regulating device 12. To avoid contact between the curtains 14 and the heat heat exchanger 2.4, rigid bars linked to the frame are positioned at the within the frame 40. The bars or the grid can be located opposite the tubes of the heat exchangers 2,4 so as not to disturb the flow.
    These characteristics described above can be taken individually or in combination and can be implemented in each embodiment which will be described later. The following embodiments differ only in the implementation for actuating and moving the curtains 14.
    According to a first embodiment illustrated in Figure 2, the motor 18 is connected to the closure element 22 via an output shaft 26 thus allowing the rotation of the closure element 22. The element closure 22 is also connected to the curtains 14, or to the sealing lips 20, by means of a wire connection 28 or any other possible guide such as a strap, a rod or a connecting rod. The regulating device 12 can comprise a single wired connection 28 or a plurality of wired connections 28, for example three per curtain 14, as illustrated in FIG. 2, this in order to guarantee a homogeneous winding / unwinding of the curtains 14. In this way a single motor 18 is sufficient to allow the movement of the curtains 14.
    FIG. 4 illustrates the embodiment device 12 according to a second embodiment. The second embodiment is similar to the embodiment ίο described above except for the actuation of the curtains 14. In this mode, a motor 18, which can correspond for example to a hydraulic or pneumatic cylinder, induces a pivoting movement and displaces a first belt 42 by means of the output shaft 26. This first belt 42 is connected to two first pinions 44 each driven by being associated with a support 16 of curtain 14 by means of a link 46 forming an axis turning the curtain. The fixed link 46 can be connected to the return spring 38 and thus retransmit the movement induced by the jack to the support 16 and therefore to the film 14. As an alternative, the fixed link 46 can pass through the support 16 without being connected to the spring return 38 and connect a first pinion 44 to a second pinion 48, the first and second pinions 44, 48 being arranged on either side of the support 16. The two second pinions 48 are also connected to each other by a second belt 50. In order to facilitate the movement of the curtains 14, the first and second belts 42, 50 comprise wire connections 52 thus connecting each belt to the two ends of a curtain 14, in particular at the level of the sealing lip 20 as illustrated in figure 4.
    FIG. 5 illustrates the embodiment device 12 according to a third embodiment. The third embodiment is similar to the embodiments described above except for the actuation of the curtains 14. In this mode, a motor 18, which can correspond for example to a hydraulic or pneumatic cylinder, induces a pivoting movement by the intermediate the output shaft 26 to an endless screw 58. The endless screw 58 contains inverted pitches and is connected to each curtain 14, for example at the sealing lip 20, by a wire connection 54, such as a strap, so that when the worm screw 58 rotates, the wire connection 54 moves, thereby causing the curtain 14 to move. The regulating device 12 may further comprise a second worm screw 56 arranged at the the opposite end of the curtains 14 and which is also connected to each curtain 14 by a wire connection 54.
    In this embodiment, the wire connection 54 may for example correspond to a wire fixed by a hole, a hook, or even a clip arranged on the curtain 14 or on the sealing lip 20 on the one hand, and on the other hand be fixed to a sliding nut on the worm 56,58.
    Although the closure element 22 is mainly described in the first embodiment, such an element can also be arranged in the second and third embodiments. In the first embodiment, the closing element 22 transmits the rotational movement induced by the motor 18 and guarantees the tightness of the regulating device 12 when the curtains 14 are in the closed configuration. The addition of a closure element 22 as described above in the second and third embodiments makes it possible to guarantee the tightness of the regulation device 12 when the curtains 14 are in the closed configuration. Such a closure element can for example be fixed to the hermetic frame 40 or to the heat exchangers 2, 4.
    As an alternative, it is conceivable not to put a closure element in embodiments 2 and 3 and to add sealing lips of complementary shape. For example, the regulating device 12 may comprise a first curtain 14 having a sealing lip 20 with a protrusion over its entire height and a second curtain 14 having a sealing lip 20 with a notch of shape complementary to the protrusion on all its height. In other words, a first curtain 14 may have a sealing lip 20 with a rib at its end while the second curtain 14 will have a sealing lip 20 with a groove of shape complementary to the rib at its end.
    The regulating device 12 according to the invention is more advantageous compared to the prior art since it guarantees a continuously adjustable partial opening thus allowing the cooling to be adapted precisely and obtaining better aerodynamic gain. In addition, the opening in the center of the heat exchangers 2,4 makes it possible to optimize their operation. On the other hand, the partial opening is located in the center of the heat exchangers 2,4 perpendicular to the tubes, thus avoiding differential expansions at the feet of tubes attached to the collection chambers 8 and therefore leaks.
    In addition, the regulating device 12 makes it possible to have a displacement a displacement of the curtains 14 which is synchronously or symmetrically as described in the previous embodiments.
    It is also possible to have a regulation device 12 making it possible to have an asymmetrical displacement of the curtains 14. We can cite by way of example the addition of a closure element 22 in two parts where each part is actuated by a separate motor 18. There is also the use of an endless screw 56, 58 with reverse pitch and of different sizes. We can also evoke the idea îo of arranging return springs 38 within each support 16 having different return forces. Finally, we can also mention the possibility of arranging two motors 18 where each motor 18 actuates a single curtain 14.
    Although the regulating device 12 is described as being arranged between the two heat exchangers 2,4, it is also possible to arrange it downstream of the downstream heat exchanger 4 or upstream of the upstream heat exchanger 2.
    It should be understood, however, that these exemplary embodiments are given by way of illustration of the subject of the invention. The invention is not limited to these embodiments described above and provided only by way of example. It encompasses various modifications, alternative forms and other variants that a person skilled in the art may envisage in the context of the present invention and in particular any combination of the various embodiments described above.
    We will now describe with reference to Figs 6 and 7 another example of implementation of the invention.
    In this example, the curtains 14 are arranged to be actuable separately.
    As illustrated in FIG. 6, the regulating device comprises a chassis
    100 of the retractable curtains 14, which chassis is located in front of the high temperature heat exchanger 4. The pins 101 of the retractable curtains 14 are fixed on the chassis 100.
    The rectangular opening 102 of the chassis 100 and the bearings 103 of the axes are placed so as to facilitate the movement of the retractable curtains 14.
    As shown in FIG. 7, the retractable curtains 14 are fixed on the axis 101 by means of a rectangular notch 105.
    At each end of the axis 101, a gear is fixed to engage on one side in a pulley 107 with an internal gear and on the other side on the actuating gear through a belt 108.
    A wire 110 is placed on each pulley. The wire paths go to the middle of the regulating device, wind around a mad pulley 111 and are then fixed on the handrail of the retractable curtains 14.
    The attachment plates of the idler pulleys also have a rectilinear notch for the movement of the handrail.
    This notch is coated with a fiber joint to limit air leakage. Above the pulley 107, a torsion spring 116 is inserted on one side into a square notch on the axle and on the other side into a cover. The spring 116 keeps the retractable curtains 14 thanks to the force applied by the spring on the axis. This spring 116 is arranged to help manage the opening and closing speeds.
    In addition to this mechanism, a grid is fixed to the frame 100 between the retractable curtains 14 and the high temperature heat exchanger 4 in order to avoid damaging the retractable curtains 14 closed when the air is blown.
    Thanks to the two actuators 120 and the pulley, gear and wire system, the retractable curtains 14 can be rolled up and unwound separately.
    The first advantage is to ensure the safety mode: in the event of a malfunction of one of the actuators; it opens the other curtain to cool whatever happens the high temperature heat exchanger 4. The second advantage is the opening in the middle of the core of the high temperature heat exchanger 4. This limits the thermal shock on the tube legs and in most cases, the opening of the retractable curtains 14 is aligned with the axis of a fan. The air flow can be well guided and maximized given the smallest opening.
    Additional functionality could be added to the mounting plates. Thus, as illustrated in FIG. 6, discharge flaps 120 can be added, which ensure the flow of air on the first exchanger when there is no need for cooling on the high temperature heat exchanger 4 , the retractable curtains 14 remaining closed. The discharge flaps 120 can be actuated by over-travel of the retractable curtains 14. The handrail then pushes a lug which opens the discharge flap.
