Description

SUPPORT D'ECHANGEURS THERMIQUES [0001] L'invention concerne le domaine des échangeurs thermiques dans un véhicule automobile, en particulier les échangeurs présents dans une façade de refroidissement. [0002] On connaît un support adapté à supporter un radiateur principal d'un véhicule automobile et, sous le radiateur principal, un échangeur thermique secondaire. [0003] L'invention vise à diminuer le nombre de pièces constitutives du système de refroidissement des fluides (liquide et gaz) utilisées pour le fonctionnement du véhicule et de faciliter leur mise en place sur la caisse. [0004] L'invention porte ainsi sur un support adapté à supporter un radiateur principal d'un véhicule automobile et, sous le radiateur principal, un échangeur thermique secondaire, caractérisé en ce que le support intègre une qui est adaptée à recevoir un groupe moto-ventilateur fixé au support. [0005] Le support permet ainsi d'assurer les fonctions de canalisation du flux d'air (du fait de la présence de la buse) et de structure porteuse des échangeurs thermiques de refroidissement. Le support permet ainsi de limiter le nombre de pièces constitutives et de réduire les coûts. [0006] Selon un premier mode de réalisation, le support comprend des premiers moyens de fixation permettant sa fixation à une face de refroidissement d'une caisse d'un véhicule. [0007] Selon un second mode de réalisation, le support comprend des seconds moyens de fixation permettant la fixation du radiateur principal et de l'échangeur thermique secondaire. [0008] Selon un troisième mode de réalisation, les seconds moyens de fixation sont disposés radialement à l'extérieur de la buse. [0009] Selon un quatrième mode de réalisation, le support comprend des ouvertures traversantes adaptées à être traversées par des conduites permettant la liaison du radiateur principal et de l'échangeur thermique secondaire à un circuit du véhicule. [0010] Selon un cinquième mode de réalisation, le même support est adapté à supporter, comme échangeur thermique secondaire, soit un échangeur air/air d'air de suralimentation, soit un échangeur air/eau relié à un refroidisseur air/eau d'air de suralimentation, selon le type de refroidissement de l'air de suralimentation du véhicule. [0011] De ce fait le même support peut être utilisé pour des types de véhicule ayant des types de refroidissement d'air de suralimentation différents. [0012] Selon un sixième mode de réalisation, le support est adapté à supporter simultanément deux échangeurs air/eau reliés à un refroidisseur air/eau d'air de suralimentation, les deux échangeurs air/eau étant disposés l'un devant l'autre sous le radiateur principal. [0013] D'autres caractéristiques et avantages de l'invention ressortiront clairement de la description qui en est faite ci-après, à titre indicatif et nullement limitatif, en référence aux dessins annexés, dans lesquels : - la figure 1 est une vue de la face arrière (face contre laquelle des échangeurs thermiques peuvent être supportés) d'un support conforme à la présente invention, - la figure 2 est une vue de la face avant (face contre laquelle un groupe moto-ventilateur peut être supporté) du support de la figure 1, - la figure 3 est une vue de la face arrière d'un ensemble comprenant le support des figures 1 et 2 ainsi qu'un radiateur principal et un échangeur air/air d'air de suralimentation fixés au support, - la figure 4 est une vue de la face avant de l'ensemble de la figure 3, - la figure 5 est une vue de la face arrière d'un ensemble comprenant le support des figures 1 et 2 ainsi qu'un radiateur principal et un échangeur air/eau adapté à être relié à un refroidisseur air/eau d'air de suralimentation, le radiateur et l'échangeur air/eau étant fixés au support, - la figure 6 est une vue de la face avant de l'ensemble de la figure 5, - la figure 7 est une vue d'un échangeur air/eau pouvant être fixé au support des figures 1 et 2, et - la figure 8 est une vue d'un assemblage de deux échangeurs air/eau de la figure 7 disposés de façon à rendre adjacentes, d'une part leur entrée d'eau, et, d'autre part, leur sortie d'eau. [0014] Un véhicule automobile comprend un moteur à combustion et un circuit de refroidissement dans lequel circule un liquide de refroidissement, le circuit comprenant des canalisations de refroidissement spécifiques réalisées dans le moteur. [0015] L'invention concerne un support 1 qui est adapté à supporter un radiateur principal 2 permettant de refroidir le liquide de refroidissement provenant du moteur. Le support 1 est adapté à être fixé à une face de refroidissement du véhicule, typiquement la façade avant du véhicule. Cette fixation est réalisée par des premiers moyens de fixation. [0016] Le radiateur principal 2 est positionné et fixé sur le support 1 par l'intermédiaire de seconds moyens de fixation, tels que des rainures, des vis ou des clips (ici, des vis 3). Dans le présent mode de réalisation, le véhicule étant équipé d'un système de climatisation, le support est également adapté à supporter un condenseur de climatisation qui, en l'occurrence, est disposé derrière le radiateur 2 et est fixé au support par l'intermédiaire de seconds moyens de fixation, tels que des rainures, des vis ou des clips. [0017] Le moteur à combustion étant associé à un turbocompresseur, le véhicule comprend également un échangeur thermique secondaire 4, 5 permettant d'évacuer vers l'extérieur l'énergie thermique provenant de la compression de l'air de suralimentation. L'échangeur thermique secondaire 4, 5, est également supporté par le support 1, sous le radiateur principal 2 (et le condenseur) et il est fixé au support par l'intermédiaire de seconds moyens de fixation, tels que des rainures, des vis ou des clips. [0018] Le support 1 permet ainsi de supporter l'ensemble des échangeurs thermiques de refroidissement (ici, radiateur principal 2, condenseur de climatisation, échangeur thermique secondaire 4, 5 pour l'air de suralimentation). Ces différents échangeurs sont disposés à la face arrière du support, c'est-à-dire à la face orientée vers le moteur. Le découplage des différents échangeurs thermiques de refroidissement de la caisse du véhicule est ainsi réalisé par le découplage du support de la caisse par des plots de découplage dont le nombre se trouve ainsi limité. [0019] Une optimisation de la structure du support 1, notamment par une définition optimale de la position d'ouvertures traversantes 6 permettant la liaison des échangeurs thermique de refroidissement aux circuits de fluides du véhicule (refroidissement, air de suralimentation) permet également d'utiliser le support pour un plus grand nombre de type de véhicules. [0020] Le véhicule comprend également un groupe moto-ventilateur qui comprend un ventilateur permettant de générer un flux d'air supplémentaire quand celui lié au déplacement du véhicule est insuffisant. [0021] Le support 1 intègre une buse 7 qui permet de canaliser le flux d'air provenant du groupe moto-ventilateur qui est par ailleurs porté par le support 1, à la face avant de ce dernier. Chaque échangeur thermique porté par le support 1 a une partie de sa surface d'échange thermique dans le prolongement de la buse 7. Les premiers et les seconds moyens de fixation 3 du support 1 sont disposés radialement à l'extérieur de la buse 7 afin de ne pas gêner l'écoulement de l'air. [0022] Le support 1 permet de regrouper à la fois la fonction de canalisation du flux d'air du fait de la présence de la buse 7 et celle de structure porteuse des échangeurs thermiques de refroidissement. Il est ainsi possible de limiter le nombre de pièces constitutives et de réduire les coûts. [0023] Un même support 1 est également adapté à supporter, comme échangeur thermique secondaire 4, 5, selon le type de refroidissement de l'air de suralimentation du véhicule, soit un échangeur air/air 4 d'air de suralimentation, soit un échangeur air/eau 5 qui est relié à un refroidisseur air/eau d'air de suralimentation. Dans le cas où le support 1 supporte un échangeur air/air 4, cet échangeur est relié par des orifices 8 d'entrée et de sortie à la conduite d'admission en air comprimé du moteur. Dans le cas où le support 1 supporte un échangeur air/eau 5, cet échangeur est relié par des orifices 9 d'entrée et de sortie au refroidisseur air/eau d'air de suralimentation. [0024] De ce fait le même support peut être utilisé dans un nombre très important de types de véhicules, aussi bien ceux dans lesquels l'air de suralimentation est refroidi par de l'air que ceux dans lesquels l'air de refroidissement est refroidi par de l'eau. De ce fait, le même support 1 peut être utilisé dans des véhicules soumis à des contraintes différentes selon les pays et la date de sortie d'usine (taux de dioxyde de carbone, emplacement vertical des échangeurs thermiques pour limiter les impacts lors de choc de piéton, etc.). [0025] Un tel support 1 permet ainsi de limiter de façon encore plus importante la diversité des façades de refroidissement des véhicules, et donc de réduire les coûts, notamment par la maximisation des volumes de production. [0026] Par ailleurs, du fait de l'encombrement plus important d'un échangeur air/air 4 d'air de suralimentation par rapport à un échangeur air/eau 5, il est possible de disposer, l'un derrière l'autre, deux échangeurs air/eau 5 dont l'épaisseur totale peut correspondre à celle d'un échangeur air/air 4. [0027] II est préférable que les deux échangeurs air/eau 5 soient identiques afin de limiter les coûts. Dans ce cas, il est préférable que l'échangeur air/eau comprenne deux boîtes à eau 10 disposées de part et d'autre sur les côtés de la surface d'échange thermique. Chaque boîte à eau comprend une excroissance latérale qui est limitée à la moitié supérieure de l'échangeur 5 et dans laquelle est réalisée un orifice 9 d'entrée ou de sortie du liquide de refroidissement. De ce fait, la conformation d'un échangeur air/eau 5 est telle que par une rotation de 180° selon un axe horizontal passant par le centre de la surface d'échange, les deux excroissances supérieures deviennent deux excroissances inférieures, et ainsi, un échangeur air/eau retourné de 180° a ses orifices d'entrée et de sortie sous et le long des mêmes orifices de l'échangeur air/eau non retourné qui lui est adjacent, ce qui facilite leur liaison au circuit de refroidissement.30The invention relates to the field of heat exchangers in a motor vehicle, in particular the exchangers present in a cooling facade. There is known a support adapted to support a main radiator of a motor vehicle and, under the main radiator, a secondary heat exchanger. The invention aims to reduce the number of component parts of the fluid cooling system (liquid and gas) used for the operation of the vehicle and facilitate their establishment on the body. The invention thus relates to a support adapted to support a main radiator of a motor vehicle and, under the main radiator, a secondary heat exchanger, characterized in that the support incorporates one which is adapted to receive a motorcycle group -ventilator attached to the support. The support thus ensures the ducting functions of the air flow (due to the presence of the nozzle) and carrying structure of the cooling heat exchangers. The support thus makes it possible to limit the number of component parts and to reduce costs. According to a first embodiment, the support comprises first fastening means for attachment to a cooling face of a body of a vehicle. According to a second embodiment, the support comprises second fixing means for fixing the main radiator and the secondary heat exchanger. According to a third embodiment, the second fixing means are arranged radially outside the nozzle. According to a fourth embodiment, the support comprises through openings adapted to be traversed by conduits for connecting the main radiator and the secondary heat exchanger to a vehicle circuit. According to a fifth embodiment, the same support is adapted to support, as a secondary heat exchanger, an air / air exchanger for charge air or an air / water heat exchanger connected to an air / water cooler. charge air, depending on the type of charge air cooling of the vehicle. As a result, the same support can be used for vehicle types with different types of charge air cooling. According to a sixth embodiment, the support is adapted to simultaneously support two air / water heat exchangers connected to a cooler air / water charge air, the two air / water exchangers being arranged one in front of the other under the main radiator. Other features and advantages of the invention will become apparent from the description which is given below, for information only and in no way limitative, with reference to the accompanying drawings, in which: - Figure 1 is a view of the rear face (opposite side against which heat exchangers can be supported) of a support according to the present invention, - Figure 2 is a view of the front face (against which side a fan motor unit can be supported) of the support FIG. 3 is a view of the rear face of an assembly comprising the support of FIGS. 1 and 2 as well as a main radiator and an air / air exchanger for charge air fixed to the support; FIG. 4 is a view of the front face of the assembly of FIG. 3; FIG. 5 is a view of the rear face of an assembly comprising the support of FIGS. 1 and 2 as well as a main radiator and a air / water exchanger adapted to be connected to u n cooler air / water charge air, the radiator and the air / water heat exchanger being fixed to the support, - Figure 6 is a view of the front face of the assembly of Figure 5, - Figure 7 is a view of an air / water heat exchanger that can be fixed to the support of FIGS. 1 and 2, and FIG. 8 is a view of an assembly of two air / water exchangers of FIG. 7 arranged so as to make adjacent, on the one hand their entry of water, and, on the other hand, their outflow of water. [0014] A motor vehicle comprises a combustion engine and a cooling circuit in which a cooling liquid circulates, the circuit comprising specific cooling ducts made in the engine. The invention relates to a support 1 which is adapted to support a main radiator 2 for cooling the coolant from the engine. The support 1 is adapted to be attached to a cooling face of the vehicle, typically the front of the vehicle. This fixing is performed by first fixing means. The main radiator 2 is positioned and fixed on the support 1 by means of second fixing means, such as grooves, screws or clips (here, screws 3). In the present embodiment, the vehicle being equipped with an air conditioning system, the support is also adapted to support an air conditioning condenser which, in this case, is arranged behind the radiator 2 and is fixed to the support by the intermediate second fastening means, such as grooves, screws or clips. The combustion engine being associated with a turbocharger, the vehicle also comprises a secondary heat exchanger 4, 5 for discharging to the outside the thermal energy from the compression of the charge air. The secondary heat exchanger 4, 5, is also supported by the support 1, under the main radiator 2 (and the condenser) and is fixed to the support by means of second fixing means, such as grooves, screws or clips. The support 1 and can support all heat exchangers cooling (here, main radiator 2, air conditioning condenser, secondary heat exchanger 4, 5 for the charge air). These different exchangers are arranged on the rear face of the support, that is to say on the face facing the motor. The decoupling of the various heat exchangers cooling the vehicle body is thus achieved by decoupling the support of the box by decoupling pads whose number is thus limited. An optimization of the structure of the support 1, in particular by an optimal definition of the position of through openings 6 allowing the connection of the cooling heat exchangers to the fluid circuits of the vehicle (cooling, charge air) also makes it possible to use support for a larger number of vehicle types. The vehicle also includes a motor-fan unit which includes a fan for generating an additional air flow when the one related to the movement of the vehicle is insufficient. The support 1 includes a nozzle 7 which can channel the air flow from the motor-fan unit which is also supported by the support 1, the front of the latter. Each heat exchanger carried by the support 1 has a part of its heat exchange surface in the extension of the nozzle 7. The first and second fixing means 3 of the support 1 are arranged radially outside the nozzle 7 so not to impede the flow of air. The support 1 allows to combine both the duct function of the air flow due to the presence of the nozzle 7 and that of the carrier structure of the cooling heat exchangers. It is thus possible to limit the number of component parts and to reduce costs. The same support 1 is also adapted to support, as a secondary heat exchanger 4, 5, depending on the type of cooling of the charge air of the vehicle, either an air / air exchanger 4 of charge air, or a air / water exchanger 5 which is connected to a cooler air / water charge air. In the case where the support 1 supports an air / air exchanger 4, this exchanger is connected by inlet and outlet ports 8 to the compressed air inlet duct of the engine. In the case where the support 1 supports an air / water exchanger 5, this exchanger is connected by the inlet and outlet ports 9 to the air / water cooler charge air. Therefore, the same support can be used in a very large number of vehicle types, both those in which the charge air is cooled by air than those in which the cooling air is cooled. by water. As a result, the same support 1 can be used in vehicles subject to different constraints depending on the country and the date of leaving the factory (carbon dioxide rate, vertical location of the heat exchangers to limit the impacts during a shock of pedestrian, etc.). Such a support 1 thus makes it possible to limit even more importantly the diversity of the cooling facades of the vehicles, and thus to reduce costs, in particular by maximizing production volumes. Furthermore, because of the larger size of an air / air exchanger 4 air charge with respect to an air / water heat exchanger 5, it is possible to arrange, one behind the other , two air / water exchangers 5 whose total thickness may correspond to that of an air / air exchanger 4. It is preferable that the two air / water exchangers 5 are identical in order to limit costs. In this case, it is preferable that the air / water exchanger comprises two water boxes 10 disposed on either side on the sides of the heat exchange surface. Each water box comprises a lateral protrusion which is limited to the upper half of the exchanger 5 and in which is formed an orifice 9 inlet or outlet of the coolant. As a result, the conformation of an air / water exchanger 5 is such that, by a 180 ° rotation along a horizontal axis passing through the center of the exchange surface, the two upper excrescences become two lower excrescences, and thus, an air / water exchanger turned 180 ° to its inlet and outlet ports under and along the same orifices of the unreversed air / water exchanger adjacent thereto, which facilitates their connection to the cooling circuit.
