Description
MODULE DE REFROIDISSEMENT POUR VÉHICULE VEHICLE COOLING MODULE
AUTOMOBILE AUTOMOTIVE
Domaine technique Technical area
[0001] L'invention se rapporte au domaine de l’automobile, et plus particulièrement au domaine de la circulation d’air pour le refroidissement du moteur et de ses équipements. [0001] The invention relates to the field of automobiles, and more particularly to the field of air circulation for cooling the engine and its equipment.
Technique antérieure Prior art
[0002] Les véhicules à moteur, qu’ils soient à combustion ou électriques, ont besoin d'évacuer les calories que génère leur fonctionnement et sont pour cela équipés d'échangeurs de chaleur. Un échangeur de chaleur de véhicule automobile comprend généralement des tubes, dans lesquels un fluide caloporteur est destiné à circuler, notamment un liquide tel que l’eau, et des éléments d’échange de chaleur reliés à ces tubes, souvent désignés par le terme « ailettes » ou « intercalaires ». Les ailettes permettent d’augmenter la surface d’échange entre les tubes et l’air ambiant. [0002] Motor vehicles, whether combustion or electric, need to remove the calories generated by their operation and are therefore equipped with heat exchangers. A motor vehicle heat exchanger generally comprises tubes, in which a heat transfer fluid is intended to circulate, in particular a liquid such as water, and heat exchange elements connected to these tubes, often designated by the term " fins ”or“ spacers ”. The fins increase the exchange surface between the tubes and the ambient air.
[0003] Toutefois, afin d’augmenter encore l’échange de chaleur entre le fluide caloporteur et l’air ambiant, il est fréquent qu’un dispositif de ventilation soit utilisé en sus, pour générer ou accroître un flux d’air dirigé vers les tubes et les ailettes. [0003] However, in order to further increase the heat exchange between the coolant and the ambient air, it is common for a ventilation device to be used in addition, to generate or increase an air flow directed towards tubes and fins.
[0004] De façon connue, un tel dispositif de ventilation comprend un ventilateur à hélice. [0004] In known manner, such a ventilation device comprises a propeller fan.
[0005] Le flux d’air généré par les pales d’un tel ventilateur est turbulent, notamment en raison de la géométrie circulaire de l’hélice, et n’atteint en général qu’une partie seulement de la surface de l’échangeur de chaleur (zone circulaire de l’échangeur faisant face à l’hélice du ventilateur). L’échange de chaleur ne se fait donc pas de façon homogène sur toute la surface des tubes et des ailettes. [0005] The air flow generated by the blades of such a fan is turbulent, in particular due to the circular geometry of the propeller, and generally only reaches part of the surface of the exchanger heat (circular area of the exchanger facing the fan impeller). The heat exchange is therefore not homogeneous over the entire surface of the tubes and fins.
[0006] En outre, lorsque la mise en marche du ventilateur ne s’avère pas nécessaire (typiquement lorsque l’échange de chaleur avec de l’air ambiant non accéléré suffit à refroidir le fluide caloporteur circulant dans l’échangeur), les pales obstruent en partie l’écoulement de l’air ambiant vers les tubes et les ailettes, ce qui
gêne la circulation d’air vers l’échangeur et limite ainsi l’échange de chaleur avec le fluide caloporteur. [0006] In addition, when switching on the fan is not necessary (typically when the heat exchange with unaccelerated ambient air is sufficient to cool the heat transfer fluid circulating in the exchanger), the blades partially obstruct the flow of ambient air to the tubes and fins, which interferes with air circulation to the exchanger and thus limits heat exchange with the heat transfer fluid.
[0007] Un tel ventilateur est en outre relativement encombrant, à cause notamment des dimensions nécessaires de l’hélice pour obtenir un refroidissement moteur effectif, ce qui rend long et délicat son intégration dans un véhicule automobile. [0007] Such a fan is also relatively bulky, in particular because of the dimensions of the propeller necessary to obtain effective engine cooling, which makes its integration into a motor vehicle long and difficult.
[0008] Cette intégration est d’autant plus compliquée dans un véhicule électrique, dont la face avant laisse peu de place pour y loger les éléments de refroidissement du véhicule. [0008] This integration is all the more complicated in an electric vehicle, the front of which leaves little room to house the vehicle's cooling elements.
[0009] Le but de l’invention est de remédier au moins partiellement à ces inconvénients. [0009] The aim of the invention is to at least partially remedy these drawbacks.

[0010] To this end, the invention relates to a cooling module for a motor vehicle, comprising at least one heat exchanger, at least one tangential turbomachine capable of creating an air flow intended to cool said at least one heat exchanger , said at least one tangential turbomachine being disposed behind said at least one heat exchanger relative to a direction of flow of said air flow in the cooling module, at least one flap disposed behind said at least one heat exchanger relative to the direction of 'flow of said air flow, and mounted to move between a first position, called the cooling module open position and a second position, called the cooling module closed position.
[0011] Ainsi, avantageusement, la turbomachine tangentielle permet de créer un flux d’air à travers tous les échangeurs thermiques avec un bien meilleur rendement que si un ventilateur à hélice était mis en œuvre. [0011] Thus, advantageously, the tangential turbomachine makes it possible to create an air flow through all the heat exchangers with a much better efficiency than if a propeller fan were implemented.

- les volets sont montés parallèlement à un axe de rotation des turbomachines tangentielles. - The flaps are mounted parallel to an axis of rotation of the tangential turbomachines.
[0013] L’invention a également pour objet un véhicule automobile comprenant une carrosserie, un pare-chocs et un module de refroidissement tel que décrit précédemment, la carrosserie définissant au moins une baie de refroidissement disposée sous le pare-chocs, le module de refroidissement étant disposé en regard de la au moins une baie de refroidissement.

Description de modes de réalisation Description of embodiments
[0020] La figure 1 illustre de manière schématique la partie avant d’un véhicule automobile 10 comportant un moteur 12. Ce moteur 12 pouvant être thermique ou électrique. Le véhicule 10 comporte notamment une carrosserie 14 et un pare-chocs 16 portés par un châssis (non représenté) du véhicule automobile 10. La carrosserie 14 définit une baie de refroidissement 18, c'est-à-dire une ouverture à travers la carrosserie 14. La baie de refroidissement 18 est ici unique. Cette baie de refroidissement 18 se trouve en partie basse de la face avant 14a de la carrosserie 14. Dans l’exemple illustré, la baie de refroidissement 18 est située sous le pare- chocs 16. Une grille 20 peut être disposée dans la baie de refroidissement 18 pour éviter que des projectiles puissent traverser la baie de refroidissement 18. Un module de refroidissement 22 est disposé en vis-à-vis de la baie de refroidissement 18. La grille 20 permet notamment de protéger ce module de refroidissement 22. [0020] Figure 1 schematically illustrates the front part of a motor vehicle 10 comprising a motor 12. This motor 12 may be thermal or electric. The vehicle 10 comprises in particular a body 14 and a bumper 16 carried by a chassis (not shown) of the motor vehicle 10. The body 14 defines a cooling bay 18, that is to say an opening through the body. 14. The cooling bay 18 is unique here. This cooling bay 18 is located in the lower part of the front face 14a of the body 14. In the example illustrated, the cooling bay 18 is located under the bumper 16. A grid 20 can be placed in the cooling bay. cooling 18 to prevent projectiles from passing through the cooling bay 18. A cooling module 22 is placed opposite the cooling bay 18. The grid 20 makes it possible in particular to protect this cooling module 22.
[0021] Le module de refroidissement 22 comprend un dispositif de ventilation 24 associé à au moins un échangeur thermique 26. [0021] The cooling module 22 comprises a ventilation device 24 associated with at least one heat exchanger 26.
[0022] Comme il ressort des figures, le dispositif de ventilation 1 comprend au moins un ventilateur tangentiel, aussi nommé turbomachine tangentielle ci-après, référencée 2, qui aspire un flux d’air F à destination de l’échangeur de chaleur ou des échangeurs de chaleur. As emerges from the figures, the ventilation device 1 comprises at least one tangential fan, also called tangential turbomachine below, referenced 2, which sucks an air flow F intended for the heat exchanger or heat exchangers.
[0023] Selon les deux modes de réalisation illustrés sur ces figures, le dispositif de ventilation 24 comprend deux turbomachines 28-1 , 28-2, disposées parallèlement l’une à l’autre. [0023] According to the two embodiments illustrated in these figures, the ventilation device 24 comprises two turbomachines 28-1, 28-2, arranged parallel to one another.
[0024] Par parallèle, on entend qu’un axe de rotation A32-1 de la turbine de la turbomachine 28-1 est parallèle à un axe de rotation A32-2 de la turbine de la turbomachine 28-2. By parallel is meant that an axis of rotation A32-1 of the turbine of the turbomachine 28-1 is parallel to an axis of rotation A32-2 of the turbine of the turbomachine 28-2.
[0025] Les deux turbomachines 28-1 , 28-2 délimitent une surface S de sortie d’air hors du module de refroidissement 22. La surface S est disposée en regard du ou des échangeurs de chaleur 26 et constitue une face arrière du dispositif de ventilation 24.
[0026] Le dispositif de ventilation 24 comprend au moins un volet 30 monté mobile entre une première position, dite position d’ouverture du module de refroidissement (figure 5) et une deuxième position, dite position de fermeture du module de refroidissement (illustrée sur les figures 2, 3, 4). The two turbomachines 28-1, 28-2 define an air outlet surface S out of the cooling module 22. The surface S is disposed opposite the heat exchanger (s) 26 and constitutes a rear face of the device. ventilation 24. The ventilation device 24 comprises at least one flap 30 movably mounted between a first position, called the open position of the cooling module (Figure 5) and a second position, called the closed position of the cooling module (illustrated on Figures 2, 3, 4).
[0027] Sur les figures 2 et 3, le dispositif de ventilation 24 comprend plusieurs volets 30 répartis sur huit rangées et disposés parallèlement aux axes de rotation A32-1 , A32-2. L’ensemble des volets 30 occupe la face arrière S du module de refroidissement. Figures 2 and 3, the ventilation device 24 comprises several flaps 30 distributed over eight rows and arranged parallel to the axes of rotation A32-1, A32-2. All of the flaps 30 occupy the rear face S of the cooling module.
[0028] Comme il ressort de ces figures, chacun des volets 30 comprend une paroi 32 montée pivotante autour d’un axe de rotation parallèle aux axes de rotations A32- 1, A32-2. As emerges from these figures, each of the flaps 30 comprises a wall 32 pivotally mounted about an axis of rotation parallel to the axes of rotation A32-1, A32-2.
[0029] En position de fermeture, chaque paroi 32 couvre une partie de la surface S. Sur les figures 2 et 3, en position de fermeture, les parois 32 des volets 30 sont jointives les uns des autres, ce qui obstrue toute la surface S. In the closed position, each wall 32 covers part of the surface S. In Figures 2 and 3, in the closed position, the walls 32 of the flaps 30 are contiguous to each other, which obstructs the entire surface S.
[0030] Dans chaque position d’ouverture, chaque paroi 32 forme localement un angle non nul avec la surface S, ce qui permet au flux d’air F de traverser le module de refroidissement 22, comme visible sur la figure 5. In each open position, each wall 32 locally forms a non-zero angle with the surface S, which allows the air flow F to pass through the cooling module 22, as shown in Figure 5.
[0031] Le module de refroidissement 22 est configuré pour positionner les volets 30 en position d’ouverture quand les turbomachines tangentielles 28-1 , 28-2 sont à l’arrêt. [0031] The cooling module 22 is configured to position the flaps 30 in the open position when the tangential turbomachines 28-1, 28-2 are stopped.
[0032] De préférence, les turbomachines sont à l’arrêt quand un débit d’air traversant le ou les échangeur(s) de chaleur du module de refroidissement 22 est supérieur ou égal à un débit d’air maximal pouvant être aspiré par les turbomachines tangentielles 28-1 , 28-2. Cette condition est notamment réalisée à haute vitesse, par exemple quand le véhicule roule sur autoroute. Preferably, the turbomachines are stopped when an air flow passing through the heat exchanger (s) of the cooling module 22 is greater than or equal to a maximum air flow that can be sucked in by the tangential turbomachines 28-1, 28-2. This condition is achieved in particular at high speed, for example when the vehicle is traveling on a motorway.
[0033] Une telle configuration, parce qu’elle permet de mettre à l’arrêt les turbomachines dès que le flux d’air généré par la vitesse du véhicule est suffisante. Une telle propriété permet par exemple pour les véhicules électriques, à assurer une réelle économie de courant et ainsi une autonomie plus longue du véhicule électrique.
[0034] Selon le mode de réalisation illustré à la figure 2, les volets 30 sont de type passif, c’est-à-dire qu’ils ne sont pas alimentés électriquement. Such a configuration, because it makes it possible to stop the turbomachines as soon as the air flow generated by the speed of the vehicle is sufficient. Such a property makes it possible, for example, for electric vehicles, to ensure a real saving of current and thus a longer autonomy of the electric vehicle. According to the embodiment illustrated in Figure 2, the flaps 30 are of the passive type, that is to say they are not electrically powered.
[0035] Ainsi, à faible vitesse du véhicule, les turbomachines 28-1 , 28-2 fonctionnent et aspirent le flux d’air F qui traverse le(s) échangeur(s) thermique(s) et ouvre les volets 30. Thus, at low vehicle speed, the turbomachines 28-1, 28-2 operate and draw in the air flow F which passes through the heat exchanger (s) and opens the shutters 30.
[0036] A vitesse élevée du véhicule, les turbomachines 28-1 , 28-2 sont mises à l’arrêt et le flux d’air directement généré par le mouvement du véhicule traverse le(s) échangeur(s) thermique(s) et ouvre les volets 30. At high vehicle speed, the turbomachines 28-1, 28-2 are stopped and the air flow directly generated by the movement of the vehicle passes through the heat exchanger (s) and opens the shutters 30.
[0037] Avantageusement, les volets sont réalisés en matériau plastique PA6 ou PA66. Advantageously, the flaps are made of PA6 or PA66 plastic material.
[0038] Selon le mode de réalisation illustré à la figure 3, les volets 30 sont pilotés par un actionneur. According to the embodiment illustrated in Figure 3, the flaps 30 are controlled by an actuator.
[0039] Ainsi, à faible vitesse du véhicule, les turbomachines 28-1 , 28-2 fonctionnent et aspirent le flux d’air F qui traverse le(s) échangeur(s) thermique(s) et ouvre les volets 30. Thus, at low vehicle speed, the turbomachines 28-1, 28-2 operate and suck in the air flow F which passes through the heat exchanger (s) and opens the shutters 30.
[0040] A vitesse élevée du véhicule, les turbomachines 28-1 , 28-2 sont mises à l’arrêt et l’actionneur déplace les volets 30 en position d’ouverture. [0040] At high vehicle speed, the turbomachines 28-1, 28-2 are stopped and the actuator moves the flaps 30 to the open position.
[0041] L’invention n’est pas limitée aux modes de réalisation illustrés. Par exemple, il a été décrit que les turbomachines fonctionnent en aspiration, c'est-à-dire qu’elle aspire l’air ambiant pour le conduire au contact des différents échangeurs thermiques. Alternativement, cependant, les turbomachines fonctionnent par soufflage. [0041] The invention is not limited to the illustrated embodiments. For example, it has been described that turbomachines operate by suction, that is to say that they suck the ambient air in order to bring it into contact with the various heat exchangers. Alternatively, however, turbomachines operate by blowing.
[0042] De plus, les volets 30 peuvent s’étendre orthogonalement aux axes de rotation A32-1 , A32-2. [0042] In addition, the flaps 30 may extend orthogonally to the axes of rotation A32-1, A32-2.
[0043] Par ailleurs, les volets 30 peuvent occuper partiellement uniquement la surface S. C’est le cas par exemple si les volets 30 sont disposés une rangée sur deux.
Furthermore, the flaps 30 can partially occupy only the surface S. This is the case, for example, if the flaps 30 are arranged every other row.
