Description

DISPOSITIF DE REFROIDISSEMENT D'UN FLUIDE CALOPORTEUR DEVICE FOR COOLING A HEAT TRANSFER FLUID
DOMAINE TECHNIQUETECHNICAL AREA
L'invention se rapporte au domaine technique du refroidissement d'un fluide caloporteur captant des calories à la traversée de conduites ménagées dans un moteur thermique ou électrique.The invention relates to the technical field of cooling a heat transfer fluid capturing calories through the passage of conduits in a heat engine or electric.
Elle vise plus particulièrement un dispositif de refroidissement de type air/liquide équipant un véhicule automobile, l'air permettant de refroidir le fluide caloporteur étant l'air ambiant capté généralement au niveau de la calandre du véhicule.It relates more particularly to a cooling device of the air / liquid type equipping a motor vehicle, the air for cooling the heat transfer fluid is the ambient air generally captured at the calender of the vehicle.
ART ANTÉRIEURPRIOR ART
De façon générale, il existe de nombreux dispositifs de refroidissement notamment avec différents étages pour prélever le fluide caloporteur à des températures différentes. Un tel dispositif a notamment été décrit par le Demandeur dans le document FR 2 815 402.In general, there are numerous cooling devices, in particular with different stages, for taking the heat transfer fluid at different temperatures. Such a device has in particular been described by the Applicant in the document FR 2 815 402.
Ce document décrit en effet un dispositif de refroidissement comportant une entrée et deux sorties à des niveaux différents. Un tel dispositif comporte une structure monobloc et n'est pas démontable.This document indeed describes a cooling device comprising an inlet and two outputs at different levels. Such a device comprises a one-piece structure and is not removable.
Ce type de structure peut cependant se révéler problématique sous certaines conditions d'utilisation en générant des chocs thermiques qui peuvent détériorer le dispositif et engendrer des fuites.This type of structure can however be problematic under certain conditions of use by generating thermal shocks that can damage the device and cause leaks.
Un premier objectif de l'invention est donc de compenser des phénomènes de dilatation pour éviter les fuites à la jonction entre deux modules assemblés.A first object of the invention is therefore to compensate for expansion phenomena to prevent leakage at the junction between two assembled modules.
On connaît également des dispositifs de refroidissement composés de plusieurs échangeurs disjoints et connectés entre eux par des durites externes. Cependant, ce type de dispositif présente de nombreux inconvénients en termes d'encombrement, de coût d'installation et de maintenance. En effet, de telles durites externes ont une durée de vie limitée et peuvent se détériorer en engendrant des fuites.Cooling devices are also known composed of several exchangers disjoint and connected together by external hoses. However, this type of device has many disadvantages in terms of size, cost of installation and maintenance. Indeed, such external hoses have a limited life and can deteriorate by generating leaks.
Ainsi, un second objectif de l'invention est de réaliser un dispositif de refroidissement compact, peu coûteux en supprimant les pièces intermédiaires et robuste dans le temps.Thus, a second object of the invention is to provide a compact cooling device, inexpensive by removing the intermediate parts and robust over time.
EXPOSE DE L'INVENTIONSUMMARY OF THE INVENTION
L'invention concerne donc un dispositif de refroidissement d'un fluide caloporteur par échange thermique avec un autre fluide comportant une entrée et au moins deux sorties agencées à des niveaux différents pour permettre de sur-refroidir le fluide caloporteur.The invention therefore relates to a cooling device of a heat transfer fluid by heat exchange with another fluid having an inlet and at least two outlets arranged at different levels to allow over-cool the heat transfer fluid.
Selon l'invention, le dispositif se caractérise en ce qu'il comporte une structure modulaire d'au moins deux modules, chaque module comportant au moins une sortie et en ce que les deux modules sont reliés hydrauliquement entre eux au moyen d'un embout mâle d'un premier module coopérant par emboîtement avec un embout femelle de forme complémentaire d'un second module.According to the invention, the device is characterized in that it comprises a modular structure of at least two modules, each module comprising at least one outlet and in that the two modules are hydraulically connected to each other by means of a connector male of a first module cooperating by interlocking with a complementary shaped female end of a second module.
Autrement dit, un tel dispositif de refroidissement peut être assemblé/démonté en au moins deux modules sans nécessiter d'opération de soudure ou la connexion par un jeu de durites externes. Un simple engagement entre l'embout mâle et l'embout femelle permet de relier hydrauliquement les deux modules en série.In other words, such a cooling device can be assembled / disassembled into at least two modules without requiring welding operation or connection by a set of external hoses. A simple engagement between the male end and the socket makes it possible to hydraulically connect the two modules in series.
Avantageusement, les embouts maie et femelle des deux modules peuvent être agencés au niveau des faces en regard des deux modules. Ainsi, lorsque l'emboîtement est réalisé entre les deux embouts mâle et femelle, les faces en regard des deux modules, qui peuvent être des faces inférieures et supérieures se rapprochent l'une de l'autre. De cette manière, une fois les deux modules assemblés par emboîtement, les embouts mâle et femelle sont invisibles et ne constituent pas d'excroissance au volume formé par le dispositif de refroidissement. En pratique, les embouts mâle et femelle des deux modules comportent chacun une forme cylindrique.Advantageously, the male and female ends of the two modules can be arranged at the facing faces of the two modules. Thus, when the interlocking is formed between the two male and female ends, the facing faces of the two modules, which may be lower and upper faces are closer to one another. In this way, once the two modules assembled by interlocking, the male and female end pieces are invisible and do not constitute an outgrowth to the volume formed by the cooling device. In practice, the male and female ends of the two modules each have a cylindrical shape.
Par conséquent, l'emboîtement des deux modules permet de supprimer deux degrés de mobilité en translation suivant le plan perpendiculaire à la direction d'emboîtement, mais laisse la rotation possible autour de l'axe de cette direction. Ainsi, il est possible de procéder à l'emboîtement des deux modules en effectuant à la fois le mouvement de translation mais également une rotation suivant le même axe si nécessaire.Consequently, the interlocking of the two modules makes it possible to eliminate two degrees of mobility in translation along the plane perpendicular to the interlocking direction, but leaves the possible rotation around the axis of this direction. Thus, it is possible to proceed to the nesting of the two modules by performing both the translational movement but also a rotation along the same axis if necessary.
Selon un mode de réalisation particulier, le dispositif de refroidissement peut comporter un joint torique au niveau de la jonction entre les embouts mâle et femelle. Un tel joint permet de réaliser une étanchéité formant un contact linéique circulaire respectivement à l'extérieur de l'embout mâle et à l'intérieur de l'embout femelle. Un tel joint torique est généralement agencé à l'intérieur d'une rainure circulaire ménagée à la surface de l'embout mâle.According to a particular embodiment, the cooling device may comprise an O-ring at the junction between the male and female ends. Such a seal makes it possible to achieve a seal forming a circular circular contact respectively outside the male end and inside the female end. Such an O-ring is generally arranged inside a circular groove formed on the surface of the male end.
Avantageusement, le module comportant un embout femelle peut comporter un tube s' étendant coaxialement avec l'embout femelle.Advantageously, the module comprising a female endpiece may comprise a tube extending coaxially with the female endpiece.
Ainsi, en fonction de la longueur du tube utilisé, il est possible de prélever le fluide caloporteur dans un premier module dans une zone non perturbée par la sortie principale.Thus, depending on the length of the tube used, it is possible to collect the heat transfer fluid in a first module in a zone undisturbed by the main output.
En pratique, le dispositif de refroidissement peut comporter des moyens de solidarisation aptes à assujettir en liaison encastrement les deux modules. Un tel moyen de solidarisation peut notamment se présenter sous la forme de clips mais également de vis, de goujon ou de sertissage réversible permettant de désolidariser les deux modules si nécessaire.In practice, the cooling device may comprise securing means adapted to subjugate in bonded connection the two modules. Such a securing means may in particular be in the form of clips but also screw, dowel or reversible crimping to separate the two modules if necessary.
Selon un mode de réalisation particulier, les deux modules peuvent être séparés par une lame d'air. De cette manière, on réalise un pont thermique entre les deux modules, ce qui confère au dispositif une importante tenue aux chocs thermiques. En effet, les deux modules peuvent se dilater librement l'un par rapport à l'autre sans générer des contraintes supplémentaires sur le module avec lequel ils sont assemblés. DESCRIPTION SOMMAIRE DES FIGURESAccording to a particular embodiment, the two modules can be separated by an air gap. In this way, a thermal bridge is made between the two modules, which gives the device an important resistance to thermal shocks. Indeed, the two modules can expand freely relative to each other without generating additional constraints on the module with which they are assembled. SUMMARY DESCRIPTION OF THE FIGURES
La manière de réaliser l'invention ainsi que les avantages qui en découlent ressortiront bien de la description du mode de réalisation qui suit, donné à titre indicatif mais non limitatif, à l'appui des figures 1 et 2 représentant deux variantes du dispositif en vue de face, conformément à l'invention.The manner of carrying out the invention as well as the advantages derived therefrom will emerge clearly from the description of the embodiment which follows, given by way of indication but without limitation, in support of FIGS. 1 and 2 showing two variants of the device in view front, according to the invention.
MANIERES DE DECRIRE L'INVENTIONWAYS TO DESCRIBE THE INVENTION
Comme déjà évoqué, l'invention concerne un dispositif de refroidissement d'un fluide caloporteur.As already mentioned, the invention relates to a device for cooling a heat transfer fluid.
Tel que représenté aux figures 1 et 2, un tel dispositif de refroidissement (1,11) comporte une entrée (2) connectée généralement par une durite avec une source de chaleur tel un moteur thermique. Il comporte également deux sorties (3,4) agencées à des niveaux différents dans le dispositif de manière à permettre de puiser le fluide caloporteur à des températures différentes en fonction du besoin.As shown in Figures 1 and 2, such a cooling device (1,11) comprises an inlet (2) connected generally by a hose with a heat source such as a heat engine. It also comprises two outlets (3, 4) arranged at different levels in the device so as to make it possible to draw the coolant at different temperatures depending on the need.
Un tel dispositif de refroidissement (1,11) comporte par ailleurs une structure modulaire d'au moins deux modules (5,6) assemblés par emboîtement pour permettre une connexion hydraulique entre les deux modules (5,6). Chaque module (5,6) comporte alors une sortie (3,4) connectée également avec une durite pour relier le dispositif de refroidissement avec un ou plusieurs dispositifs annexes.Such a cooling device (1,11) further comprises a modular structure of at least two modules (5,6) assembled by interlocking to allow a hydraulic connection between the two modules (5,6). Each module (5, 6) then has an outlet (3, 4) also connected with a hose for connecting the cooling device with one or more additional devices.
La connexion hydraulique entre les deux modules (5,6) est par ailleurs réalisée par emboîtement d'un embout mâle (7) positionné sur un premier module (6) dans un embout femelle (8) positionné sur un second module (5). Tel que représenté, ces embouts mâle et femelle (7,8) sont disposés sur respectivement les faces inférieure et supérieure des deux modules (5,6) de manière à positionner les différentes entrées (2) et sorties (3,4) dans un même plan. Cependant, d'autres variantes sont envisageables et l'invention ne se limite pas à cet unique mode de réalisation illustré. La face inférieure (9) du premier module (6) fait alors face à la face supérieure (10) du second module (5) et de cette manière, la zone d'emboîtement entre les deux modules (5,6) est totalement intégrée dans le volume formé par le dispositif de refroidissement (1,11).The hydraulic connection between the two modules (5, 6) is furthermore made by interlocking a spigot (7) positioned on a first module (6) in a socket (8) positioned on a second module (5). As shown, these male and female ends (7, 8) are arranged on the lower and upper faces of the two modules (5, 6), respectively, so as to position the various inlets (2) and outlets (3, 4) in a same plan. However, other variants are conceivable and the invention is not limited to this single illustrated embodiment. The lower face (9) of the first module (6) then faces the upper face (10) of the second module (5) and in this way, the interlocking zone between the two modules (5, 6) is fully integrated in the volume formed by the cooling device (1,11).
Par ailleurs, un joint torique (12) peut être agencé sur l'embout mâle (7) de manière à réaliser une étanchéité au niveau de la connexion entre deux modules (5,6).Furthermore, an O-ring (12) can be arranged on the spigot (7) so as to provide a seal at the connection between two modules (5, 6).
Par ailleurs, une lame d'air (16) permet de réaliser un pont thermique entre les deux modules (5,6) et ainsi d'éviter la formation de chocs thermiques à la jonction entre les deux modules (5,6).Moreover, an air gap (16) makes it possible to create a thermal bridge between the two modules (5, 6) and thus to avoid the formation of thermal shocks at the junction between the two modules (5, 6).
Des moyens de solidarisation (14,15) permettent d'immobiliser les deux modules (5,6) en position l'un par rapport à l'autre.Means (14, 15) for securing the two modules (5, 6) in position relative to one another.
Tel que représenté à la figure 1, les moyens de solidarisation (14) peuvent se présenter sous la forme de clips ou de bagues de sertissages amovibles coopérant avec deux portions planes émergeant des faces inférieure (9) et supérieure (10) des deux modules (5,6).As shown in FIG. 1, the securing means (14) may be in the form of clips or removable crimping rings cooperating with two flat portions emerging from the lower (9) and upper (10) faces of the two modules ( 5.6).
Tel que représenté à la figure 2, les moyens de solidarisation (15) peuvent également se présenter sous la forme de vis, de rivets ou analogues qui coopèrent également avec deux portions planes des deux faces en regard (9,10).As shown in Figure 2, the securing means (15) may also be in the form of screws, rivets or the like which also cooperate with two planar portions of the two facing faces (9,10).
L'un des deux modules (5) peut également comporter un tube (13) s'étendant coaxialement avec l'embout femelle (8) de manière à capter le fluide caloporteur à l'intérieur du module (5) à une température déterminée. II ressort de ce qui précède qu'un dispositif de refroidissement conforme à l'invention présente de multiples avantages et notamment :One of the two modules (5) may also comprise a tube (13) extending coaxially with the socket (8) so as to capture the heat transfer fluid inside the module (5) at a predetermined temperature. It follows from the foregoing that a cooling device according to the invention has multiple advantages and in particular:
• il présente une structure simple modulaire permettant de réaliser une multitude de dispositifs de refroidissement différents à partir d'un nombre restreint de modules standardisés ;• it has a simple modular structure allowing to realize a multitude of different cooling devices from a limited number of standardized modules;
• il fournit un volume minimum puisque il est dépourvu de connexion extérieure entre deux modules ;• it provides a minimum volume since it has no external connection between two modules;
• il permet de palier aux phénomènes de dilatation pouvant engendrer des fuites à la jonction entre deux modules. • It helps to overcome the expansion phenomena that can cause leakage at the junction between two modules.
