La présente invention revendique la priorité de la demande française N°2108771 déposée le 19.08.2021 dont le contenu (texte, dessins et revendications) est ici incorporé par référence. The present invention claims the priority of French application No. 2108771 filed on 08.19.2021, the content of which (text, drawings and claims) is incorporated herein by reference.
Domaine technique de l’invention Technical field of the invention
L’invention concerne les systèmes d’échange de chaleur à radiateur de type air/air. The invention relates to air/air type radiator heat exchange systems.
Etat de la technique State of the art
Dans certains domaines, comme par exemple celui des véhicules (éventuellement de type automobile), on utilise des systèmes d’échange de chaleur à radiateur de type air/air. Par exemple, ce type de système d’échange de chaleur peut faire partie d’un circuit de refroidissement et/ou de chauffage. Ainsi, dans un véhicule un tel système d’échange de chaleur peut faire partie d’un circuit de refroidissement d’un moteur du groupe motopropulseur (ou GMP). In certain fields, such as for example that of vehicles (possibly of the automotive type), air/air type radiator heat exchange systems are used. For example, this type of heat exchange system can be part of a cooling and/or heating circuit. Thus, in a vehicle, such a heat exchange system can be part of a cooling circuit of an engine of the powertrain (or GMP).
Dans certains de ces systèmes d’échange de chaleur le radiateur est alimenté en air par un convoyeur d’air avec interposition d’une pièce d’interface (parfois appelée « échangeur »). Plus précisément, le radiateur comprend une première face d’entrée propre à recevoir de l’air, et la pièce d’interface comprend une deuxième face d’entrée propre à recevoir de l’air (issu du convoyeur d’air) et une première face de sortie couplée à la première face d’entrée du radiateur pour l’alimenter en air. In some of these heat exchange systems, the radiator is supplied with air by an air conveyor with the interposition of an interface piece (sometimes called an “exchanger”). More specifically, the radiator comprises a first inlet face capable of receiving air, and the interface part comprises a second inlet face capable of receiving air (coming from the air conveyor) and a first outlet face coupled to the first inlet face of the radiator to supply it with air.
Actuellement, pour assurer l’étanchéité destinée à éviter les fuites d’air, les bords du radiateur (qui délimitent sa première face d’entrée) et les bords de la pièce d’interface (qui délimitent sa première face de sortie) sont recouverts d’une mousse en élastomère (comme par exemple de l’EPDM (Ethylène- Propylène-Diène Monomère)). Mais un tel recouvrement s’avère complexe à réaliser et onéreux. En outre, ce type de recouvrement a du mal à résister aux températures élevées, comme c’est le cas lorsque l'air à refroidir à une température supérieure à 150°C. Currently, to ensure the seal intended to prevent air leaks, the edges of the radiator (which delimit its first inlet face) and the edges of the interface part (which delimit its first outlet face) are covered an elastomeric foam (such as EPDM (Ethylene- Propylene-Diene Monomer)). But such a recovery proves to be complex to achieve and expensive. In addition, this type of covering has difficulty withstanding high temperatures, as is the case when the air to be cooled to a temperature above 150°C.
L’invention a donc notamment pour but d’améliorer la situation. The aim of the invention is therefore in particular to improve the situation.
Présentation de l’invention Presentation of the invention
Elle propose notamment à cet effet un système d’échange de chaleur comprenant un radiateur de type air/air et comprenant une première face d’entrée propre à recevoir de l’air, et une pièce d’interface comprenant une deuxième face d’entrée propre à recevoir de l’air à transférer et une première face de sortie couplée à la première face d’entrée pour l’alimenter en air transféré. It proposes in particular for this purpose a heat exchange system comprising a radiator of the air/air type and comprising a first inlet face capable of receiving air, and an interface part comprising a second inlet face capable of receiving air to be transferred and a first outlet face coupled to the first inlet face to supply it with transferred air.
Ce système d’échange de chaleur se caractérise par le fait que : This heat exchange system is characterized by the fact that:
- son radiateur comprend sur chacun de deux premiers bords parallèles de sa première face d’entrée deux premières nervures parallèles, et - its radiator comprises on each of the first two parallel edges of its first inlet face two first parallel ribs, and
- sa pièce d'interface comprend sur chacun de deux deuxièmes bords parallèles de sa première face de sortie deux secondes nervures parallèles et imbriquées avec les premières nervures correspondantes afin d’offrir une étanchéité. - its interface part comprises on each of two second parallel edges of its first exit face two second parallel ribs and overlapping with the corresponding first ribs in order to provide sealing.
Cette imbrication sur toute la longueur des premier et deuxième bords sur deux côtés du système permet avantageusement d’obtenir une étanchéité à l’air en double chicane de qualité et supportant les températures élevées, sans avoir besoin d’utiliser une mousse en élastomère. This interlocking over the entire length of the first and second edges on two sides of the system advantageously makes it possible to obtain quality double baffle airtightness that withstands high temperatures, without the need to use an elastomer foam.
Le système d’échange de chaleur selon l’invention peut comporter d’autres caractéristiques qui peuvent être prises séparément ou en combinaison, et notamment : The heat exchange system according to the invention may comprise other characteristics which may be taken separately or in combination, and in particular:

- son radiateur peut comprendre sur ses premiers bords, au niveau d'une première partie d’extrémité, deux troisièmes logements. Dans ce cas, sa pièce d’interface peut comprendre sur ses deuxièmes bords, au niveau d’une première partie d’extrémité, deux pattes de couplage logées au moins partiellement et respectivement dans les troisièmes logements afin de coupler la première face de sortie à la première face d’entrée ; - its radiator can comprise on its first edges, at the level of a first end part, two third housings. In this case, its interface part may comprise on its second edges, at a first end part, two coupling lugs housed at least partially and respectively in the third housings in order to couple the first output face to the first entry face;
- en présence de la dernière option, son radiateur peut comprendre sur au moins l’un de ses premiers bords, au niveau d’une seconde partie d’extrémité opposée à sa première partie d’extrémité, un trou fileté. Dans ce cas, sa pièce d’interface peut comprendre sur au moins l’un de ses deuxièmes bords, au niveau d’une seconde partie d’extrémité opposée à sa première partie d’extrémité, une patte de fixation munie d'un trou traversant traversé par une vis vissée dans le trou fileté afin d’assurer la solidarisation fixe de la pièce d’interface au radiateur ; - in the presence of the last option, its radiator may comprise on at least one of its first edges, at the level of a second end part opposite its first end part, a threaded hole. In this case, its interface piece may comprise on at least one of its second edges, at a second end part opposite its first end part, a fixing lug provided with a hole crossing crossed by a screw screwed into the threaded hole in order to ensure the fixed connection of the interface part to the radiator;
- il peut comprendre un convoyeur d’air comprenant une troisième face d’entrée propre à recevoir l’air et une deuxième face de sortie couplée à la deuxième face d’entrée pour l’alimenter en air convoyé issu de la troisième face d’entrée en vue de son transfert vers le radiateur ; - it may comprise an air conveyor comprising a third inlet face capable of receiving the air and a second outlet face coupled to the second inlet face to supply it with air conveyed from the third face of the entry for transfer to radiator;
- en présence de la dernière option, la deuxième face de sortie peut être couplée à la deuxième face d’entrée par clippage. - in the presence of the last option, the second exit side can be coupled to the second entry side by clipping.
L’invention propose également un véhicule, éventuellement de type automobile, et comprenant un circuit de refroidissement et/ou de chauffage comportant au moins un système d’échange de chaleur du type de celui présenté ci-avant.

L’invention a notamment pour but de proposer un système d’échange de chaleur SE dans lequel l’étanchéité entre la première face d’entrée FE1 du radiateur RA et la première face de sortie FS1 de la pièce d’interface PI est assurée notamment par imbrication de nervures N1 et N2. The object of the invention is in particular to propose a heat exchange system SE in which the seal between the first inlet face FE1 of the radiator RA and the first outlet face FS1 of the interface part PI is ensured in particular by nesting of ribs N1 and N2.
Dans ce qui suit, on considère, à titre d’exemple non limitatif, que le système d’échange de chaleur SE selon l’invention est destiné à faire partie d’un circuit de refroidissement et/ou de chauffage. Mais l’invention n’est pas limitée à cette application.

In addition, it is considered in what follows, by way of non-limiting example, that the cooling and/or heating circuit is intended to equip a vehicle of the automotive type, such as a car for example. But the invention is not limited to this application. Indeed, the circuit can equip any vehicle (land, sea (or river), or air), any installation (possibly industrial), and any building.
On a schématiquement illustré sur les figures 1 et 2 un exemple de réalisation d’un système d’échange de chaleur SE selon l’invention, respectivement en cours d’assemblage et après assemblage. There is schematically illustrated in Figures 1 and 2 an embodiment of a heat exchange system SE according to the invention, respectively during assembly and after assembly.
Comme illustré sur les figures 1 et 2, un système d’échange de chaleur SE, selon l’invention, comprend au moins un radiateur RA et une pièce d’interface (ou échangeur) PL As illustrated in Figures 1 and 2, a heat exchange system SE, according to the invention, comprises at least one radiator RA and an interface part (or exchanger) PL
Le radiateur RA est de type air/air et comprend une première face d’entrée FE1 qui est propre à recevoir de l’air issu de la pièce d’interface PI. De plus, il comprend deux premiers bords B1 parallèles entre eux, participant à la délimitation de sa première face d’entrée FE1 , et sur chacun desquels sont définies deux premières nervures N1 parallèles entre elles (voir figures 2 et 3). La pièce d’interface PI comprend une deuxième face d’entrée FE2 qui est propre à recevoir de l’air devant être transféré vers la première face d’entrée FE1 du radiateur RA, et une première face de sortie FS1 qui est couplée à cette première face d’entrée FE1 pour l’alimenter en air transféré depuis la deuxième face d’entrée FE2. De plus, elle comprend deux deuxièmes bords B2 parallèles entre eux, participant à la délimitation de sa première face de sortie FS1 , et sur chacun desquels sont définies deux secondes nervures N2 parallèles entre elles et imbriquées avec les premières nervures N1 correspondantes afin d’offrir une étanchéité à l’air (voir figures 2 et 3). The radiator RA is of the air/air type and comprises a first inlet face FE1 which is capable of receiving air from the interface part PI. In addition, it comprises two first edges B1 parallel to each other, participating in the delimitation of its first entry face FE1, and on each of which are defined two first ribs N1 parallel to each other (see figures 2 and 3). The PI interface part comprises a second inlet face FE2 which is capable of receiving air to be transferred to the first inlet face FE1 of the radiator RA, and a first outlet face FS1 which is coupled to this first inlet face FE1 to supply it with air transferred from the second inlet face FE2. In addition, it comprises two second edges B2 parallel to each other, participating in the delimitation of its first exit face FS1, and on each of which are defined two second ribs N2 parallel to each other and nested with the corresponding first ribs N1 in order to offer airtightness (see figures 2 and 3).
On entend ici par « imbrication » le fait que les premières N1 et secondes N2 nervures des premier B1 et deuxième B2 bords qui se correspondent sont sensiblement parallèles entre elles en étant intercalés en se recouvrant partiellement selon une suite de type (N1 , N2, N1 , N2) qui permet de définir une espèce de double chicane, comme illustré sur la figure 3. Here, the term "nesting" means that the first N1 and second N2 ribs of the first B1 and second B2 edges which correspond are substantially parallel to each other, being intercalated and partially overlapping according to a sequence of the type (N1, N2, N1 , N2) which makes it possible to define a kind of double baffle, as illustrated in figure 3.
Grâce à cette imbrication sur toute la longueur des premier B1 et deuxième B2 bords qui se correspondent sur deux côtés du système SE (ici verticaux), on obtient une étanchéité à l’air en double chicane de qualité et supportant les températures élevées, sans avoir besoin de recouvrir d’une mousse en élastomère au moins les premiers bords B1 qui délimitent la première face d’entrée FE1 du radiateur RA et les deuxièmes bords B2 qui délimitent la première face de sortie FS1 de la pièce d’interface PL Thanks to this nesting over the entire length of the first B1 and second B2 edges which correspond on two sides of the SE system (here vertical), we obtains quality double baffle airtightness that can withstand high temperatures, without the need to cover with an elastomer foam at least the first edges B1 which delimit the first inlet face FE1 of the radiator RA and the second edges B2 which delimit the first exit face FS1 of the interface part PL
Par exemple, et comme illustré non limitativement sur les figures 2 et 3, les premières nervures N1 de chacun des deux premiers bords B1 peuvent délimiter un premier logement L1 , et les secondes nervures N2 de chacun des deux deuxièmes bords B2 peuvent délimiter un deuxième logement L2 qui loge l’une des premières nervures N1 correspondantes, alors que dans le même temps l’une de ces secondes nervures N2 se retrouve logée dans le premier logement L1 correspondant. On réalise ainsi l’imbrication qui assure l’étanchéité à l’air en double chicane au moins sur les premier B1 et deuxième B2 bords qui se correspondent sur les deux côtés (verticaux) du système SE. Egalement par exemple, et comme illustré non limitativement sur les figures 1 et 4, la pièce d’interface PI peut comprendre un troisième bord B3, perpendiculaire à ses deuxièmes bords B2 et délimitant la première face de sortie FS1 (ici dans sa partie supérieure). Ce troisième bord B3 comprend une extension EB qui définit un décrochement DE et qui recouvre partiellement une partie de la face (ici supérieure) FR du radiateur RA, laquelle est perpendiculaire à la première face d’entrée FE1 , afin de participer à l’étanchéité à l’air. For example, and as illustrated without limitation in Figures 2 and 3, the first ribs N1 of each of the first two edges B1 can delimit a first housing L1, and the second ribs N2 of each of the two second edges B2 can delimit a second housing L2 which houses one of the corresponding first ribs N1, while at the same time one of these second ribs N2 is housed in the corresponding first housing L1. This produces the interlocking which ensures airtightness in a double baffle at least on the first B1 and second B2 edges which correspond on the two (vertical) sides of the SE system. Also for example, and as illustrated without limitation in Figures 1 and 4, the PI interface part may include a third edge B3, perpendicular to its second edges B2 and delimiting the first output face FS1 (here in its upper part) . This third edge B3 comprises an extension EB which defines a recess DE and which partially covers part of the face (here upper) FR of the radiator RA, which is perpendicular to the first inlet face FE1, in order to participate in the sealing in the air.
On comprendra que ce décrochement DE (ici vers le haut) permet à l’extension EB d’atteindre la première face d’entrée FE1 du radiateur RA un peu en- dessous de la face supérieure FR, puis de recouvrir partiellement cette face supérieure FR (en formant une espèce de « casquette »). En d’autres termes, le décrochement DE définit une espèce de « chicane » qui permet de réduire très notablement la quantité d’air pouvant sortir par le troisième bord B3 de la pièce d’interface PI, à l’interface avec la première face d’entrée FE1 du radiateur RA. It will be understood that this recess DE (here upwards) allows the extension EB to reach the first inlet face FE1 of the radiator RA a little below the upper face FR, then to partially cover this upper face FR (by forming a kind of "cap"). In other words, the recess DE defines a kind of "chicane" which makes it possible to very significantly reduce the quantity of air that can exit through the third edge B3 of the interface part PI, at the interface with the first face input FE1 of the radiator RA.
On notera, comme illustré non limitativement sur les figures 1 , 2 et 5, que le radiateur RA peut comprendre sur ses deux premiers bords B1 , au niveau d’une première partie d’extrémité PE11 (ici inférieure), deux troisièmes logements L3. Dans ce cas, la pièce d’interface PI peut comprendre sur ses deuxièmes bords B2, au niveau d’une première partie d’extrémité PE12 (ici inférieure), deux pattes de couplage PC qui sont logées au moins partiellement et respectivement dans les troisièmes logements L3 afin de coupler la première face de sortie FS1 à la première face d’entrée FE1 et donc la pièce d’interface PI au radiateur RA. It will be noted, as illustrated without limitation in Figures 1, 2 and 5, that the radiator RA may comprise on its first two edges B1, at the level of a first end part PE11 (here lower), two third L3 slots. In this case, the PI interface part may comprise on its second edges B2, at a first end part PE12 (here lower), two PC coupling tabs which are housed at least partially and respectively in the third housings L3 in order to couple the first output face FS1 to the first input face FE1 and therefore the interface part PI to the radiator RA.
Un tel agencement est particulièrement avantageux lors de l’assemblage du système SE car il permet de commencer par introduire partiellement les deux pattes de couplage PC dans les troisièmes logements L3 par une petite translation en biais (ici de haut en bas), puis d’entraîner en rotation la pièce d’interface PI vers la première face d’entrée FE1 du radiateur RA afin d’imbriquer les premières N1 et secondes N2 nervures des premier B1 et deuxième B2 bords qui se correspondent. Ensuite, on translate légèrement la pièce d’interface PI par rapport au radiateur RA (ici vers le bas), afin de terminer l’introduction des deux pattes de couplage PC dans leurs troisièmes logements L3 et de placer la partie terminale libre de l’extension EB du troisième bord B3 sur la face supérieure FR du radiateur RA (si possible en contact pour optimiser l’étanchéité, mais sans exercer de pression lorsque le radiateur RA comprend de fragiles ailettes (par exemple en aluminium)). Le résultat de l’introduction partielle des deux pattes de couplage PC dans les deux troisièmes logements L3 est illustré sur la figure 1 . Such an arrangement is particularly advantageous when assembling the system SE because it makes it possible to start by partially introducing the two PC coupling lugs into the third housings L3 by a small translation at an angle (here from top to bottom), then rotating the PI interface part towards the first inlet face FE1 of the radiator RA in order to nest the first N1 and second N2 ribs of the first B1 and second B2 edges which correspond. Then, the interface part PI is slightly translated with respect to the radiator RA (here downwards), in order to complete the introduction of the two coupling legs PC into their third housings L3 and to place the free end part of the extension EB of the third edge B3 on the upper face FR of the radiator RA (if possible in contact to optimize sealing, but without exerting pressure when the radiator RA comprises fragile fins (for example aluminum)). The result of the partial introduction of the two coupling tabs PC into the two third housings L3 is illustrated in figure 1 .
On notera, comme illustré non limitativement et au moins partiellement sur les figures 1 et 5, que le radiateur RA peut aussi comprendre sur au moins l’un de ses premiers bords B1 , au niveau d’une seconde partie d’extrémité PE21 (ici supérieure) opposée à sa première partie d’extrémité PE11 (ici inférieure), un trou fileté TF. Dans ce cas, la pièce d’interface PI peut comprendre sur au moins l’un de ses deuxièmes bords B2, au niveau d’une seconde partie d’extrémité PE22 (ici supérieure) opposée à sa première partie d’extrémité PE12 (ici inférieure), une patte de fixation PF munie d’un trou traversant TT. Ainsi, le trou traversant TT peut être traversé par une vis qui est vissée dans le trou fileté TF du radiateur RA afin d’assurer la solidarisation fixe de la pièce d’interface PI au radiateur RA, et de participer à l’étanchéité du fait du placage engendré par le vissage. On comprendra que ce vissage est réalisé une fois que la pièce d’interface PI a été correctement et entièrement positionnée par rapport au radiateur RA (et donc ici après l’entraînement en rotation et la translation finale vers le bas). It will be noted, as illustrated without limitation and at least partially in FIGS. 1 and 5, that the radiator RA can also comprise on at least one of its first edges B1, at the level of a second end part PE21 (here upper) opposite its first end part PE11 (here lower), a threaded hole TF. In this case, the PI interface part can comprise on at least one of its second edges B2, at the level of a second end part PE22 (here upper) opposite to its first end part PE12 (here bottom), a fixing bracket PF provided with a through hole TT. Thus, the through hole TT can be crossed by a screw which is screwed into the threaded hole TF of the radiator RA in order to ensure the fixed attachment of the interface part PI to the radiator RA, and to participate in the sealing due to of the veneer generated by the screwing. It will be understood that this screwing is carried out once that the PI interface part has been correctly and fully positioned with respect to the RA radiator (and therefore here after the rotation drive and the final downward translation).
Dans une variante de réalisation non illustrée, la solidarisation fixe de la pièce d’interface PI au radiateur RA pourrait se faire par clippage grâce à des premiers et seconds moyens de clippage coopérant ensemble et définis respectivement sur la pièce d’interface PI et le radiateur RA. In a variant embodiment not shown, the fixed attachment of the interface part PI to the radiator RA could be done by clipping thanks to first and second clipping means cooperating together and defined respectively on the interface part PI and the radiator AR.
On notera également, comme illustré non limitativement sur les figures 1 et 2, que le système SE peut aussi comprendre un convoyeur d’air CA comprenant une troisième face d’entrée FE3, propre à recevoir l’air (destiné au radiateur RA via la pièce d’interface PI), et une deuxième face de sortie FS2, couplée à la deuxième face d’entrée FE2 pour l’alimenter en air convoyé issu de la troisième face d’entrée FE3 en vue de son transfert vers le radiateur RA.It will also be noted, as illustrated without limitation in FIGS. 1 and 2, that the system SE can also comprise an air conveyor CA comprising a third inlet face FE3, capable of receiving the air (intended for the radiator RA via the interface part PI), and a second output face FS2, coupled to the second input face FE2 to supply it with air conveyed from the third input face FE3 with a view to its transfer to the radiator RA.
Par exemple, et comme illustré non limitativement sur les figures 1 et 2, la deuxième face de sortie FS2 du convoyeur d’air CA peut être couplée à la deuxième face d’entrée FE2 de la pièce d’interface PI par clippage. A cet effet la pièce d’interface PI peut comprendre des premiers moyens de clippage répartis sur sa périphérie (par exemple des pattes de clippage) et coopérant avec des seconds moyens de clippage correspondants et définis sur la périphérie de la deuxième face de sortie FS2 du convoyeur d’air CA (par exemple des trous traversants). Dans une variante de réalisation non illustrée, la solidarisation fixe du convoyeur d’air CA à la pièce d’interface PI pourrait se faire par vissage. For example, and as illustrated without limitation in Figures 1 and 2, the second output face FS2 of the air conveyor CA can be coupled to the second input face FE2 of the interface part PI by clipping. To this end, the PI interface part may comprise first clipping means distributed over its periphery (for example clipping lugs) and cooperating with corresponding second clipping means and defined on the periphery of the second output face FS2 of the AC air conveyor (e.g. through holes). In a variant embodiment not shown, the fixed attachment of the air conveyor CA to the interface part PI could be done by screwing.
On notera également que la pièce d’interface PI et/ou le convoyeur d’air CA peu(ven)t être réalisé(e)(s) par moulage d’une matière plastique ou synthétique. Par exemple, lorsque l’air doit avoir une température élevée, on peut utiliser du PA6 GF35 (Polyamide 6 chargé avec 35 % de fibres de verre). It should also be noted that the interface part PI and/or the air conveyor CA can be made by molding a plastic or synthetic material. For example, when the air must have a high temperature, PA6 GF35 (Polyamide 6 filled with 35% glass fibers) can be used.
