Description

Dispositif de connexion de l'entrée/sortie d'un aérotherme d'un véhicule automobile et véhicule automobile comportant un tel dispositif Device for connecting the inlet / outlet of a heater of a motor vehicle and a motor vehicle comprising such a device
La présente invention concerne un dispositif de connexion de la sortie ou de l'entrée d'un aérotherme et un véhicule automobile comportant un tel dispositif.The present invention relates to a device for connecting the output or the input of a heater and a motor vehicle comprising such a device.
Le document EP 1 013 981 décrit un dispositif de connexion de deux éléments tubulaires, utilisable notamment pour raccorder les extrémités de deux tubes d'un système de climatisation d'un véhicule automobile. Ce dispositif comporte deux parties de verrouillage qui équipent, chacune, une extrémité d'un élément tubulaire, et qui coopèrent par emboîtement et rotation relative de l'une par rapport à l'autre, pour le raccordement de ces deux éléments tubulaires. Ce type de dispositif permet simplement de connecter l'extrémité d'un premier élément tubulaire à l'extrémité d'un second élément tubulaire qui vient directement prolonger le premier.The document EP 1 013 981 describes a device for connecting two tubular elements, usable in particular for connecting the ends of two tubes of an air conditioning system of a motor vehicle. This device comprises two locking parts which each equip an end of a tubular element, and which cooperate by interlocking and relative rotation of one relative to the other, for the connection of these two tubular elements. This type of device simply makes it possible to connect the end of a first tubular element to the end of a second tubular element which directly extends the first.
Les véhicules automobiles comportent, de manière standard, un aérotherme qui est un échangeur de chaleur dont la fonction est de réchauffer l'air puisé dans l'habitacle.Motor vehicles comprise, as standard, a heater that is a heat exchanger whose function is to heat the air drawn into the passenger compartment.
Ce réchauffement est obtenu par un échange calorifique entre le liquide de refroidissement de la boucle chaude et l'air puisé dans l'habitacle. La boucle chaude est une branche du circuit de refroidissement moteur qui alimente les organes de chauffage de l'habitacle en liquide de refroidissement réchauffé par le moteur. L' aérotherme comprend donc un premier conduit dans lequel circule l'air puisé dans l'habitacle. Ce premier conduit est mis, sur une longueur suffisante, au contact d'un second conduit qui provient ou fait partie de la boucle chaude, afin de réchauffer l'air qu'il contient ; les calories du liquide de refroidissement chaud du second conduit sont transférées à l'air contenu dans le premier conduit sur toute la longueur de contact des deux conduits. Ces deux conduits forment les deux circuits parallèles de l' aérotherme. Ces deux circuits sont fixes et ne permettent aucune modification de l'orientation des conduits, notamment, en sortie de l' aérotherme, sans une re-conception partielle du bloc de chauffage du véhicule.This heating is obtained by a heat exchange between the coolant of the hot loop and air drawn into the passenger compartment. The hot loop is a branch of the engine cooling circuit that supplies the heating elements of the passenger compartment with coolant heated by the engine. The heater thus comprises a first duct in which circulates air drawn into the passenger compartment. This first conduit is placed, over a sufficient length, in contact with a second conduit which is or is part of the hot loop, to heat the air it contains; the calories of the hot coolant of the second duct are transferred to the air contained in the first duct over the entire length of contact of the two ducts. These two ducts form the two parallel circuits of the heater. These two circuits are fixed and do not allow any modification of the orientation of the ducts, in particular, at the outlet of the heater, without a partial re-design of the heating block of the vehicle.
Un but de la présente invention est de proposer un dispositif de connexion de la sortie d'un aérotherme qui remédie à tout ou partie des inconvénients précités.An object of the present invention is to provide a device for connecting the output of a heater which overcomes all or part of the aforementioned drawbacks.

Les deux conduits 1 et 2 sont reliés d'un même côté du boîtier 3, au niveau de la première paroi d'extrémité 32.As shown in FIG. 1, the heater comprises a first duct 1 and a second duct 2 which are parallel, arranged close to one another and which both extend longitudinally, one along the length of the duct. 'other. The connection device according to the invention comprises a housing 3 which is, in this case, substantially cylindrical and flat. The section of the housing 3 is substantially circular. The housing 3 comprises a cylindrical wall 31, a first and a second end wall 32, 33 which each close one end of the cylindrical wall 31. The first and second end walls 32, 33 are circular. The two end walls 32 and 33 are parallel to each other and perpendicular to the longitudinal axis X of the cylindrical wall 31 of the housing 3. The housing 3 also comprises a connecting duct 4 which passes through the housing 3 substantially in the center of the two end walls 32 and 33 and which has the longitudinal axis, the X axis above. This connecting pipe 4 makes it possible to connect the second pipe 2 to the housing 3. The first end wall 32 has a first opening 35 (see FIG. 2), connected to a first connecting pipe 51 (see FIG. 2), which is connected to the first duct 1. The two ducts 1 and 2 are connected on the same side of the casing 3, at the level of the first end wall 32.
Comme représenté sur la figure 1, la seconde paroi d'extrémité 33 comporte une lumière de distribution 34 qui est annulaire. Un second tube de raccordement 52, qui est orienté vers l'extérieur du boîtier 3 dépasse de cette lumière de distribution 34 et permet de raccorder le boîtier 3 à un premier conduit de sortie d'aérotherme (non représenté).As shown in FIG. 1, the second end wall 33 has a dispensing slot 34 which is annular. A second connecting tube 52, which is facing outward of the housing 3 protrudes from this dispensing light 34 and makes it possible to connect the housing 3 to a first heater outlet duct (not shown).
En référence aux figures 1 et 2, le boîtier 3 forme une chambre annulaire qui entoure le conduit de raccordement 4 et qui est ouverte au niveau de la première ouverture 35 et de la lumière de distribution 34. Le conduit de raccordement 4 est fermé et ne communique pas avec la chambre formée par le boîtier 3. En revanche, la première ouverture 35 et, par conséquent, le premier tube de raccordement 51, et la lumière de distribution 34, communiquent entre eux par l'intermédiaire de la chambre formée par le boîtier 3. Le conduit de raccordement 4 est rectiligne et présente, au niveau de la première paroi d'extrémité 32, une première extrémité 41 qui est reliée à une extrémité du second conduit 2 et, au niveau de la seconde paroi d'extrémité 33, une seconde extrémité 42 qui peut être reliée à l'extrémité d'un second conduit de sortie d'aérotherme (non représenté). Le conduit de raccordement 4 peut également ne pas être rectiligne ce qui permet une disposition différente des conduits de sortie d'aérotherme. Comme représenté sur les figures 1 et 2, la lumière de distribution 34 est fermée par une pièce de fermeture 6. Cette pièce de fermeture 6 comporte une partie plate et circulaire 61 qui vient obstruer la lumière de distribution 34. Cette partie plate 61 comporte un trou central pour le passage du conduit de raccordement 4 et porte le second tube de raccordement 52 précité. La pièce de fermeture 6 est montée à rotation autour du conduit de raccordement 4.With reference to FIGS. 1 and 2, the casing 3 forms an annular chamber which surrounds the connection duct 4 and which is open at the level of the first opening 35 and the distribution lumen 34. The connecting duct 4 is closed and does not communicate with the chamber formed by the housing 3. On the other hand, the first opening 35 and, consequently, the first connection tube 51, and the distribution light 34, communicate with each other via the chamber formed by the housing 3. The connecting duct 4 is rectilinear and has, at the first end wall 32, a first end 41 which is connected to one end of the second duct 2 and, at the second end wall 33 a second end 42 which can be connected to the end of a second heater output duct (not shown). The connecting duct 4 may also not be straight which allows a different arrangement of the air heater outlet ducts. As shown in FIGS. 1 and 2, the dispensing light 34 is closed by a closure piece 6. This closure piece 6 has a flat circular portion 61 which obstructs the dispensing light 34. This flat portion 61 comprises a central hole for the passage of the connecting pipe 4 and carries the second connecting tube 52 mentioned above. The closing piece 6 is rotatably mounted around the connecting pipe 4.
En référence à la figure 2, le second conduit 2 est raccordé à une première extrémité 41 du conduit de raccordement 4 et ne communique en rien avec l'intérieur du boîtier 3. Le tube de raccordement 4 est inséré dans un passage ménagé à travers le boîtier 3. Le conduit de raccordement 4 comporte deux bossages annulaires 44 qui le calent dans le passage précité et empêchent sa translation axiale dans ce passage. Dans le mode de réalisation représenté, le passage dans lequel est inséré le conduit de raccordement 4 est fermé mais selon un autre mode de réalisation non représenté, ce passage est ouvert et le conduit de raccordement 4 permet de fermer de manière étanche le passage afin d'assurer l'étanchéité du boîtier 3. La pièce de fermeture 6 est montée à rotation dans le boîtier 3. Cette pièce de fermeture 6 comporte une seconde ouverture 38, prolongée, vers l'extérieur du boîtier 3, par le second tube de raccordement 52. La partie plate 61 de la pièce de fermeture 6 vient en appui contre la face interne de la seconde paroi d'extrémité 33, au niveau d'une bande annulaire interne 71 et d'une bande annulaire externe 72. La bande annulaire interne 71 est une bande située entre le bord de la section du conduit de raccordement 4 et le bord interne de la lumière annulaire 34 (i. e. le bord interne correspondant au bord circulaire de plus petit diamètre). La bande annulaire externe 72 correspond à la bande réservée entre le bord de la seconde paroi d'extrémité 33 et le bord externe de la lumière de distribution 34 (i.e. le bord externe étant le bord circulaire de plus grand diamètre). Des moyens de calage (non représentés) permettent d'éviter que la pièce de fermeture 6 ne s'enfonce dans le boîtier 3.With reference to FIG. 2, the second duct 2 is connected to a first end 41 of the connecting duct 4 and does not communicate with the inside of the casing 3. The connecting tube 4 is inserted into a passageway formed through the housing 3. The connecting duct 4 comprises two annular bosses 44 which wedge it in the aforementioned passage and prevent its axial translation in this passage. In the embodiment shown, the passage into which the connecting duct 4 is inserted is closed, but according to another embodiment, not shown, this passage is open and the connecting duct 4 makes it possible to seal the passage in order to sealing the housing 3. The closure piece 6 is rotatably mounted in the housing 3. This closure part 6 comprises a second opening 38, extended towards the outside of the housing 3, by the second connection tube 52. The flat portion 61 of the closure piece 6 bears against the inner face of the second end wall 33, at an inner annular band 71 and an outer annular band 72. The inner annular band 71 is a band between the edge of the section of the connecting duct 4 and the inner edge of the annular light 34 (ie the inner edge corresponding to the circular edge of smaller diameter). The outer annular band 72 corresponds to the reserved band between the edge of the second end wall 33 and the outer edge of the dispensing lumen 34 (ie the outer edge being the larger diameter circular edge). Calibration means (not shown) make it possible to prevent the closure piece 6 from sinking into the casing 3.
La variante de réalisation représentée sur la figure 3 diffère du premier mode de réalisation en ce que le conduit de raccordement 4 forme une seule et même pièce avec le boîtier 3.The embodiment variant shown in FIG. 3 differs from the first embodiment in that the connecting duct 4 forms a single piece with the housing 3.
Sur la figure 4 qui représente un second mode de réalisation, la pièce de fermeture 6 prend appui sur une surface inclinée au niveau du bord externe de la lumière de distribution 34. Dans ce second mode de réalisation, la bande annulaire externe 72 est inclinée vers l'axe X du conduit de raccordement 4, en direction de l'extérieur du boîtier 3, ce qui assure une meilleure étanchéité et évite que la pièce de fermeture 6 ne s'enfonce dans le boîtier 3. De même, la pièce de fermeture 6 comporte une bande annulaire protubérante 64 qui coopère avec la lumière 34 de manière à venir obturer cette dernière au niveau de la surface de la seconde paroi d'extrémité 33. Ainsi, la pièce de fermeture 6 et la seconde paroi d'extrémité 33 forment une surface uniforme et plane.In FIG. 4 which represents a second embodiment, the closure piece 6 bears on an inclined surface at the outer edge of the dispensing light 34. In this second embodiment, the outer annular band 72 is inclined towards the X axis of the connecting pipe 4, towards the outside of the housing 3, which ensures a better seal and prevents the closure part 6 from sinking into the housing 3. Similarly, the closure part 6 comprises a protruding annular band 64 which cooperates with the light 34 so as to close the latter at the surface of the second end wall 33. Thus, the closure piece 6 and the second end wall 33 form a uniform and flat surface.
Selon un troisième mode de réalisation du dispositif de l'invention, la pièce de fermeture 6 comporte une portion cylindrique 62, qui prolonge la partie plate 61, longitudinalement selon la direction de l'axe X. Cette portion cylindrique et longitudinale 62 coopère avec la paroi cylindrique 31 du boîtier 3. La paroi cylindrique 31 comporte alors un bossage annulaire 37, orienté vers l'intérieur du boîtier 3 et qui est disposé à proximité de la première paroi d'extrémité 32. La pièce de fermeture 6 comporte alors, sur sa portion cylindrique 62, une gorge annulaire 66, qui vient coopérer avec le bossage 37. Ce type de pièce de fermeture 6 permet d'obtenir une bonne étanchéité et une mise en mouvement facile de la pièce de fermeture 6 qui est correctement guidée et ne risque donc pas de se désaxer par rapport à son axe de rotation qui, dans le cas présent, se confond avec l'axe X précité. L'utilisation du dispositif de l'invention est la suivante. Le premier conduit 1 est connecté au premier tube de raccordement 51. L'utilisateur saisit ensuite le second tube de raccordement 52 et fait tourner la pièce de fermeture 6 dans le boîtier 3, autour du conduit de raccordement 4. Le second tube de raccordement 52 tourne dans la lumière de distribution 34 et peut ainsi être déplacé dans n'importe quelle position située à 360° autour de la seconde extrémité 42 du conduit de raccordement 4. Lorsque le second tube de raccordement 52 est correctement placé, l'utilisateur peut le raccorder à un premier conduit de sortie d'aérotherme. Un second conduit de sortie d'aérotherme est également relié à la seconde extrémité 42 du conduit de raccordement 4. Par ailleurs, le dispositif de l'invention permet également de modifier la position du premier conduit de sortie d'aérotherme lorsque celui-ci est déjà raccordé au boîtier 3.According to a third embodiment of the device of the invention, the closing piece 6 comprises a cylindrical portion 62, which extends the flat portion 61, longitudinally in the direction of the axis X. This cylindrical and longitudinal portion 62 cooperates with the cylindrical wall 31 of the housing 3. The cylindrical wall 31 then comprises an annular boss 37, oriented towards the inside of the housing 3 and which is arranged close to the first end wall 32. The closure part 6 then comprises, on its cylindrical portion 62, an annular groove 66, which cooperates with the boss 37. This type of closure piece 6 provides a good seal and easy movement of the closure part 6 which is properly guided and does not therefore risk not to offset its axis of rotation, which in this case, coincides with the aforementioned axis X. The use of the device of the invention is as follows. The first duct 1 is connected to the first connection tube 51. The user then grabs the second connection tube 52 and rotates the closure piece 6 in the housing 3, around the connecting duct 4. The second connecting tube 52 rotates in the dispensing lumen 34 and can thus be moved to any position located 360 ° around the second end 42 of the connecting duct 4. When the second connecting tube 52 is correctly placed, the user can connect to a first air heater outlet duct. A second duct outlet duct is also connected to the second end 42 of the connecting duct 4. Furthermore, the device of the invention also makes it possible to modify the position of the first duct outlet duct when it is already connected to the housing 3.
Dans tous les modes de réalisation précités, le conduit de raccordement peut soit faire partie intégrante du boîtier 3, comme dans la variante du premier mode de réalisation, soit être une pièce séparée, montée dans le boîtier 3. Le quatrième mode de réalisation représenté sur la figure 6 est en fait une variante du mode de réalisation représenté sur la figure 4. Dans ce quatrième mode de réalisation, deux tubes 81 et 82 qui sont coudés sont montés d'un même côté du boîtier 3, respectivement sur une extrémité 41 du conduit de raccordement 4 et sur l'extrémité libre du premier tube de raccordement 51. Ces deux tubes 81 et 82 sont coudés vers l'extérieur de manière à ce que l'écart entre les deux tubes 81 et 82 soit plus grand que l'écart entre le premier conduit 1 et le conduit de raccordement 4. Ces deux tubes 81 et 82 qui sont rigides permettent d'augmenter l'entre axe et de le régler, à la demande, par rotation de chaque tube 81, 82 autour des extrémités 41 et 51. Il est également possible de munir la seconde extrémité 42 du conduit de raccordement 4 et l'extrémité libre du second tube de raccordement 52 à deux autres tubes tels que précités qui peuvent également faire office de manivelle.In all the aforementioned embodiments, the connecting duct may either be an integral part of the casing 3, as in the variant of the first embodiment, or it may be a separate part, mounted in the casing 3. The fourth embodiment shown in FIG. FIG. 6 is actually a variant of the embodiment shown in FIG. 4. In this fourth embodiment, two tubes 81 and 82 which are bent are mounted on the same side of the housing 3, respectively on one end 41 of the connecting pipe 4 and on the free end of the first connecting tube 51. These two tubes 81 and 82 are bent outwards so that the distance between the two tubes 81 and 82 is greater than the the two ducts 81 and 82 which are rigid make it possible to increase the distance between the axis and to adjust it, on demand, by rotation of each tube 81, 82 around the ducts 1 and 4. 41 and 51. It is also possible to provide the second end 42 of the connecting pipe 4 and the free end of the second connecting tube 52 to two other tubes as mentioned above which can also act as a crank.
Selon un cinquième mode de réalisation représenté sur la figure 7, le second tube de raccordement 52 est relié à un tube 87 par des moyens formant rotule. Dans le mode de réalisation particulier ici représenté, les moyens formant rotule comportent une coupelle 53, disposée au niveau de l'extrémité libre du second tube de raccordement 52 et un bulbe 88 qui équipe une extrémité du tube 87 et qui est monté dans la coupelle 53. Le bulbe 88 et la coupelle forment une rotule qui permet d'orienter le tube 87 dans plusieurs directions autour de l'axe du second tube de raccordement 52, et confère ainsi une liberté angulaire supplémentaire au dispositif de l'invention. Bien évidemment, le bulbe 88 et la coupelle 53 comportent chacun une ouverture qui permet le passage du fluide à travers le tube 87, quelle que soit l'orientation du tube 87. Il est également possible selon l'invention, d'équiper l'une et/ou l'autre des deux extrémités, 41 et 42, du conduit de raccordement 4 de coupelles et de tubes formant rotule avec ces coupelles. Il est également possible d'équiper l'extrémité libre du premier tube de raccordement 51 d'une telle coupelle et d'un tel tube formant rotule avec la coupelle. According to a fifth embodiment shown in Figure 7, the second connecting tube 52 is connected to a tube 87 by means forming a ball joint. In the particular embodiment shown here, the ball-shaped means comprise a cup 53, disposed at the free end of the second connecting tube 52 and a bulb 88 which equips one end of the tube 87 and which is mounted in the cup 53. The bulb 88 and the cup form a ball joint which makes it possible to orient the tube 87 in several directions around the axis of the second connecting tube 52, and thus confers additional angular freedom to the device of the invention. Of course, the bulb 88 and the cup 53 each have an opening which allows the passage of the fluid through the tube 87, regardless of the orientation of the tube 87. It is also possible according to the invention to equip the one and / or the other of the two ends, 41 and 42, of the connection duct 4 of cups and tubes forming a ball with these cups. It is also possible to equip the free end of the first connecting tube 51 of such a cup and of such a tube forming a ball joint with the cup.
