Pour des questions de normes de prestation au client (rapidité de réparation, sécurité, etc.), les véhicules automobiles intègrent de plus en plus des modules interchangeables placés stratégiquement sous le capot du moteur. Cela permet notamment, lorsque qu'un choc a lieu à faible vitesse, de pouvoir repartir grâce l'impact d'un minimum de pièces facilement remplaçables. A titre d'exemple, il est important que le radiateur du système de refroidissement du moteur ne soit pas touché afin de pouvoir repartir après le choc. Cependant, il est difficile avec la compacité des porte-à-faux actuels de pouvoir limiter l'intrusion de la traverse jusqu'au radiateur.For issues of customer service standards (speed of repair, safety, etc.), motor vehicles are increasingly incorporating interchangeable modules strategically placed under the engine hood. This allows, especially when a shock takes place at low speed, to be able to restart thanks to the impact of a minimum of easily replaceable parts.

A cet effet, l'invention se rapporte à un système de refroidissement notamment pour moteur comportant une structure sur laquelle sont montés un radiateur et un dispositif de ventilation caractérisé en ce qu'il comporte un système de déplacement de l'ensemble radiateur - dispositif de ventilation en cas de chocs.For this purpose, the invention relates to a cooling system, in particular for an engine comprising a structure on which a radiator and a ventilation device are mounted, characterized in that it comprises a system for moving the radiator assembly ventilation in case of shocks.

L'invention se rapporte également à un véhicule automobile caractérisé en ce qu'il comporte un système de refroidissement conforme à l'une quelconques des variantes ci-dessus.The invention also relates to a motor vehicle characterized in that it comprises a cooling system according to any one of the above variants.
D'autres particularités et avantages ressortiront clairement de la description qui en est faite ci-après, à titre indicatif et nullement limitatif, en référence aux dessins annexés, dans lesquelles : - la figure 1 est une vue en perspective d'un système de refroidissement selon l'invention ; - la figure 2 est une représentation en coupe partielle selon l'axe M-Il de la figure 1 ; - la figure 3 est une vue en perspective du dispositif de fixation selon l'invention ; - les figures 4 et 5 sont des vues de dessus d'un système de refroidissement selon l'invention avant et après un choc ;Other features and advantages 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 perspective view of a cooling system according to the invention; - Figure 2 is a representation in partial section along the axis M-II of Figure 1; FIG. 3 is a perspective view of the fixing device according to the invention; - Figures 4 and 5 are top views of a cooling system according to the invention before and after an impact;
Dans l'exemple illustré à la figure 1 , on peut voir un système de refroidissement généralement annoté 1 . Il comporte principalement une structure 3, un condenseur 5, un radiateur 7, un dispositif de ventilation 9 et un système de déplacement 11 de l'ensemble condenseur 5 - radiateur 7 - dispositif de ventilation 9.In the example illustrated in Figure 1, we can see a generally annotated cooling system 1. It mainly comprises a structure 3, a condenser 5, a radiator 7, a ventilation device 9 and a displacement system 11 of the condenser 5 - radiator 7 - ventilation device 9.
Comme visible aux figures 1 et 4, la structure 3 est montée fixe préférentiellement entre deux bras 13 et 15, également appelés brancards, de la caisse 17 du véhicule automobile. De manière préférée, la structure 3 est montée sensiblement parallèlement par rapport à l'axe transversal A dudit véhicule automobile aux jonctions entre les bras 13, 15 et leur absorbeur respectif 19, 21 . On peut voir notamment que les absorbeurs 19 et 21 sont reliés entre eux par une traverse 23.As can be seen in FIGS. 1 and 4, the structure 3 is fixedly mounted preferentially between two arms 13 and 15, also called stretchers, of the body 17 of the motor vehicle. Preferably, the structure 3 is mounted substantially parallel to the transverse axis A of said motor vehicle at the junctions between the arms 13, 15 and their respective absorbers 19, 21. It can be seen in particular that the absorbers 19 and 21 are interconnected by a cross member 23.
Dans l'exemple illustré à la figure 1 , on peut voir que le condenseur 5, le radiateur 7 et le dispositif de ventilation 9 forment un empilement qui permet aux deux premiers (c'est-à- dire situés vers l'avant du véhicule automobile) de profiter du courant d'air généré par le dernier (c'est-à-dire le plus proche du moteur). De façon connue, pour éviter la récupération d'air chaud venant du moteur, l'ensemble condenseur 5 - radiateur 7 - dispositif de ventilation 9 peut comporter des cloisons anti- recyclage 25 et 27. Cette configuration étant connue, elle ne sera pas d'avantage expliquée ci-après.In the example illustrated in FIG. 1, it can be seen that the condenser 5, the radiator 7 and the ventilation device 9 form a stack which allows the first two (that is to say situated towards the front of the vehicle). automobile) to take advantage of the air flow generated by the latter (that is to say the closest to the engine). In known manner, to avoid the recovery of hot air from the engine, the condenser unit 5 - radiator 7 - ventilation device 9 may comprise anti-recycling partitions 25 and 27. This configuration being known, it will not advantage explained below.
Bien entendu, si le véhicule automobile ne comporte pas de climatisation, le système de refroidissement 1 n'a pas la nécessité de comporter un condenseur 5. De plus, le dispositif de ventilation 9 peut être placé non pas derrière le radiateur 7 mais entre la traverse 23 et l'ensemble condenseur 5 - radiateur 7.Of course, if the motor vehicle does not include air conditioning, the cooling system 1 does not have the need to include a condenser 5. In addition, the ventilation device 9 can be placed not behind the radiator 7 but between the crossbar 23 and the condenser 5 - radiator 7.
Le système de déplacement 11 comporte un dispositif de fixation 29 de l'ensemble condenseur 5 - radiateur 7 - dispositif de ventilation 9 par rapport à la structure 3 et un dispositif de blocage 31 dudit dispositif de fixation 29.The displacement system 11 comprises a device 29 for fixing the condenser 5 - radiator 7 - ventilation device 9 with respect to the structure 3 and a locking device 31 for the fixing device 29.
Le dispositif de fixation 29 comporte deux corps principaux 33 et 35 situés l'un et l'autre sur un axe B sensiblement vertical médian de la longueur du radiateur 7 (sensiblement parallèle à l'axe A). Les deux corps principaux 33 et 35 sont ainsi respectivement montés au niveau de la partie haute et de la partie basse de l'ensemble condenseur 5 - radiateur 7 - dispositif de ventilation 9. Préférentiellement, les corps 33 et 35 sont identiques afin de diminuer le nombre de pièces du dispositif de fixation 29.The fixing device 29 comprises two main bodies 33 and 35 located one on the other on a substantially vertical axis B median of the length of the radiator 7 (substantially parallel to the axis A). The two main bodies 33 and 35 are thus respectively mounted at the level of the upper part and the lower part of the condenser 5 - radiator 7 - ventilation device 9. Preferably, the bodies 33 and 35 are identical in order to reduce the number of parts of the fixing device 29.
Comme illustré dans l'exemple de la figure 3, on peut voir un corps 33 ou 35, selon l'invention, qui forme une attache 37 destinée à recevoir l'ensemble condenseur 5 - radiateur 7 - dispositif de ventilation 9 et comprenant un doigt 39 formant un crochet sensiblement cylindrique destiné à coopérer avec une attache 41 solidaire de la structure 3.As illustrated in the example of Figure 3, we can see a body 33 or 35, according to the invention, which forms a fastener 37 for receiving the condenser unit 5 - radiator 7 - ventilation device 9 and comprising a finger 39 forming a substantially cylindrical hook intended to cooperate with a fastener 41 secured to the structure 3.
L'attache 37 comporte un crochet 43 destiné à s'ancrer contre la partie supérieure du radiateur 7 et un épaulement 45 destiné à s'ancrer sur le rebord 47 courant sur la longueur du radiateur 7 comme visible à la figure 2. On peut également voir que le corps principal 33 comporte une extrémité basse 47 formant mortaise pour une extrémité du condenseur 5 comme visible à la figure 2.The fastener 37 comprises a hook 43 intended to be anchored against the upper part of the radiator 7 and a shoulder 45 intended to be anchored on the flange 47 running along the length of the radiator 7 as can be seen in FIG. see that the main body 33 has a lower end 47 forming a mortise for one end of the condenser 5 as shown in Figure 2.
Le doigt 39 formant crochet, essentiellement formé en un matériau élastique tel qu'un polymère, comporte une gorge annulaire 49 dans laquelle s'ancre l'attache 41 au moyen d'une agrafe 51 sensiblement en forme de U. Le doigt 39 peut être, par exemple, venu de moulage avec le corps principal 33. On s'aperçoit que la configuration du dispositif de fixation 29 qui comporte deux corps principaux 33 et 35 permet à l'ensemble condenseur 5 - radiateur 7 - dispositif de ventilation 9 de pouvoir imprimer une rotation trigonométrique ou rétrograde par rapport à la structure 3 au moyen d'un glissement de chaque agrafe 51 de l'attache 41 dans chaque gorge 49 du doigt 39. Par la nature élastique du doigt 39, l'ensemble condenseur 5 - radiateur 7 - dispositif de ventilation 9 est avantageusement suspendu sur la structure 3 sans transmissions de vibrations.The hooking finger 39, essentially formed of an elastic material such as a polymer, has an annular groove 49 into which the clip 41 is anchored by means of a substantially U-shaped clip 51. The finger 39 can be , for example, come from molding with the main body 33. It can be seen that the configuration of the fastening device 29 which comprises two main bodies 33 and 35 allows the condenser unit 5 - radiator 7 - ventilation device 9 to be able to print a trigonometric or retrograde rotation with respect to the structure 3 by means of a sliding of each clip 51 of the fastening 41 in each groove 49 of the finger 39. By the elastic nature of the finger 39, the condenser 5 - radiator 7 - ventilation device 9 is advantageously suspended on the structure 3 without transmitting vibrations.
Comme illustré dans l'exemple de la figure 1 , le dispositif de blocage 31 est destiné à interdire la liberté de rotation offerte par la configuration du dispositif de fixation 29. Il comporte deux plots 53 et 55 montés sensiblement verticalement et préférentiellement symétriquement par rapport à l'axe B dans la partie basse de la structure 3. Ils sont l'un et l'autre montés en vis-à-vis d'une des faces principales du radiateur 7 (la face avant dans l'exemple illustré à la figure 1 ) et respectivement sensiblement à l'aplomb des cloisons anti-recyclage 27 et 25.As illustrated in the example of Figure 1, the locking device 31 is intended to prohibit the freedom of rotation offered by the configuration of the fixing device 29. It comprises two studs 53 and 55 mounted substantially vertically and preferably symmetrically with respect to the axis B in the lower part of the structure 3. They are both mounted vis-à-vis one of the main faces of the radiator 7 (the front face in the example shown in FIG. 1) and respectively substantially vertically above the anti-recycling partitions 27 and 25.
Préférentiellement, les plots 53 et 55 sont du type sécable, c'est-à-dire qu'ils comportent une zone de faiblesse propre à céder en cas de contrainte exercée par le radiateur 7. De manière préférée, le seuil prédéterminé d'énergie est inférieur à l'énergie nécessaire pour casser par cisaillement une cloison anti-recyclage 25 ou 27. Le seuil est borné préférentiellement à l'énergie induite par l'inertie d'un véhicule automobile à une vitesse de 16 km. h"1 qui coïncide avec l'énergie maximale que peut supporter un absorbeur 19, 21 . A titre d'exemple pour un véhicule automobile de 1 ,5 t à 16 km. h" 1 , cela représente, en utilisant l'expression E = Xζxmxv2 , une énergie d'environ 15 kJ. Les plots 53 et 55 peuvent être montés dans des évidements de la structure 3, par exemple, par emmanchement à force, par clippage ou par vissage afin qu'ils puissent être remplaçable.Preferably, the studs 53 and 55 are of the breakable type, that is to say that they comprise a zone of weakness capable of yielding in the event of stress exerted by the radiator 7. Preferably, the predetermined threshold of energy is lower than the energy required to break by shear an anti-recycling partition 25 or 27. The threshold is limited preferably to the energy induced by the inertia of a motor vehicle at a speed of 16 km. h "1 which coincides with the maximum energy that can support an absorber 19, 21. By way of example for a motor vehicle 1, t 5 to 16 km. h" 1, this is, by using the expression E = Xζxmxv 2 , an energy of about 15 kJ. The pads 53 and 55 can be mounted in recesses of the structure 3, for example by press fitting, by clipping or by screwing so that they can be replaceable.
L'explication des différentes phases du système de déplacement 11 lors d'un choc vont être décrites ci-dessous en référence aux figures 4 et 5. Une première phase correspond à l'état de déformation entre l'état initial comme illustré à la figure 4 et l'état dans lequel la traverse 23 commence à toucher une des cloisons anti-recyclage 25 ou 27. Si la déformation s'arrête à cette phase, le véhicule automobile peut repartir et la caisse 17 du véhicule automobile n'a pas besoin d'être changée.The explanation of the different phases of the displacement system 11 during an impact will be described below in FIG. 4 and 5. A first phase corresponds to the state of deformation between the initial state as illustrated in FIG. 4 and the state in which the crosspiece 23 begins to touch one of the anti-recycling partitions 25 or 27. If the deformation stops at this phase, the motor vehicle can restart and the body 17 of the motor vehicle does not need to be changed.
Dans une deuxième phase, une partie de l'énergie fournie par l'inertie du véhicule automobile est transmise au radiateur 7 par successivement la traverse 23 et une ou les deux cloisons anti-recyclage 25 et/ou 27. Dans une troisième phase, l'énergie transmise devient supérieure au seuil prédéterminé ce qui entraîne la scission d'un des plots 53 ou 55. Le dispositif de fixation 29 devient alors libre en rotation par rapport à la structure 3. Dans une quatrième phase, l'énergie transmise est utilisée pour pivoter l'ensemble condenseur 5 - radiateur 7 - dispositif de ventilation 9 par rapport à la structure 3. A ce stade, le véhicule automobile peut repartir pour un garage et le nombre de pièces à changer n'est pas conséquent.In a second phase, a portion of the energy supplied by the inertia of the motor vehicle is transmitted to the radiator 7 by successively the cross member 23 and one or both anti-recycling partitions 25 and / or 27. In a third phase, the transmitted energy becomes greater than the predetermined threshold which causes the splitting of one of the pads 53 or 55. The fixing device 29 then becomes free in rotation with respect to the structure 3. In a fourth phase, the transmitted energy is used to rotate the condenser assembly 5 - radiator 7 - ventilation device 9 with respect to the structure 3. At this stage, the motor vehicle can restart for a garage and the number of parts to be changed is not consequent.
Dans une cinquième phase, le pivotement maximal est atteint et la ou les cloisons anti-recyclage 25 et/ou 27 cèdent à leur tour. Cela correspond à l'exemple illustré à la figure 5. Après la cinquième phase si l'énergie n'est pas totalement absorbée, c'est-à-dire si le choc a eu lieu préférentiellement à une vitesse supérieure à 16 km. h"1 , l'intégrité de l'ensemble condenseur 5 - radiateur 7 - dispositif de ventilation 9 ne peut plus être préservée. Néanmoins, on comprend que si le choc a lieu à une vitesse inférieure à 16 km. h"1 , l'ensemble condenseur 5 - radiateur 7 - dispositif de ventilation 9 sera préservé et il suffira de remplacer le plot 55 et/ou 53 cassé(s) pour bloquer à nouveau le dispositif de fixation 29.In a fifth phase, the maximum pivoting is reached and the anti-recycling partition (s) 25 and / or 27 in turn yield. This corresponds to the example shown in Figure 5. After the fifth phase if the energy is not fully absorbed, that is to say if the shock has occurred preferentially at a speed greater than 16 km. h "1, the integrity of the entire condenser 5 - radiator 7 - ventilation device 9 can no longer be maintained, however, it is understood that if the impact occurs at a speed below 16 km h.." 1, l condenser assembly 5 - radiator 7 - ventilation device 9 will be preserved and it will suffice to replace the pad 55 and / or 53 broken (s) to lock again the fixing device 29.
Bien entendu, la présente invention ne se limite pas à l'exemple illustré mais est susceptible de diverses variantes et modifications qui apparaîtront à l'homme de l'art. En particulier, il peut être prévu au moins un impacteur dédié pour remplacer la fonction de transmission d'énergie des cloisons anti-recyclage 25 ou 27.Of course, the present invention is not limited to the illustrated example but is susceptible of various variations and modifications that will occur to those skilled in the art. In particular, it can be provided at least one dedicated impactor for replace the energy transmission function of the anti-recycling partitions 25 or 27.
De plus, le dispositif de fixation 29 peut être de configuration différente comme, par exemple, comporter une interaction différente des corps principaux 33 et 35 par rapport à la structure 3 ou comporter des corps principaux 33 et 35 étant monobloc avec le radiateur 7 et/ou le condenseur 5 et/ou le dispositif de ventilation 9. Il peut également être envisagé qu'il n'y ait qu'une seule attache 41 sur la partie supérieure ou inférieure de la structure 3 pour limiter les coûts en la remplaçant par un simple trou circulaire.In addition, the fixing device 29 may be of different configuration, for example, comprising a different interaction of the main bodies 33 and 35 with respect to the structure 3 or comprising main bodies 33 and 35 being integral with the radiator 7 and / or or the condenser 5 and / or the ventilation device 9. It can also be envisaged that there is only one fastener 41 on the upper or lower part of the structure 3 to limit the costs by replacing it with a simple circular hole.
Enfin, il peut être envisager un dispositif de blocage 31 de configuration différente de part, par exemple, l'endroit où sont montés les plots 53 et 55 ou la constitution dudit dispositif de blocage 31 . Finally, it is possible to envisage a blocking device 31 of different configuration from, for example, the place where the pads 53 and 55 are mounted or the constitution of said blocking device 31.
