Description

La présente invention concerne un module d'échange de chaleur, comprenant un échangeur principal et au moins un échangeur secondaire comportant chacun un corps muni de tubes de circulation de fluide, et des moyens d'encliquetage pour fixer l'échangeur secondaire sur l'échangeur principal de sorte qu'un même flux d'air puisse traverser les corps respectifs desdits échangeurs.The present invention relates to a module for exchanging heat, comprising a main exchanger and at least one secondary exchanger each comprising a body provided with tubes fluid circulation, and latching means for fix the secondary exchanger on the main exchanger of so that the same air flow can pass through the bodies respective of said exchangers.

De tels échangeurs se présentent généralement sous la forme d'un corps muni de tubes de circulation de fluide et d'ailettes d'échange de chaleur avec le milieu extérieur. Ce corps est disposé entre deux boítes collectrices qui distribuent le fluide dans les tubes de circulation.Such exchangers are generally in the form a body provided with fluid circulation tubes and fins heat exchange with the outside environment. This body is arranged between two manifolds that distribute the fluid in the circulation tubes.

Il est connu d'assembler sur un échangeur principal, tel qu'un radiateur de refroidissement d'un moteur de véhicule automobile, un ou plusieurs échangeurs secondaires afin de constituer un ensemble, appelé encore module, prêt à être installé dans le véhicule. Cet échangeur secondaire est constitué le plus souvent d'un refroidisseur d'air de suralimentation du moteur ou d'un condenseur de climatisation.It is known to assemble on a main exchanger, such than a vehicle engine cooling radiator automobile, one or more secondary exchangers in order to constitute a set, also called module, ready to be installed in the vehicle. This secondary exchanger is usually consisting of an air cooler supercharging of the engine or an air conditioning condenser.

L'assemblage du ou des échangeurs secondaires sur l'échangeur principal est obtenu généralement par l'intermédiaire de pattes solidaires de l'échangeur secondaire et de vis introduites dans les boítes collectrices de l'échangeur principal. On a également proposé des systèmes d'assemblage par emboítement ou encliquetage des boítes collectrices.The assembly of the secondary exchanger (s) on the exchanger principal is usually obtained through lugs integral with the secondary exchanger and screws introduced into the exchanger manifolds main. Assembly systems have also been proposed by fitting or snapping on the manifolds.

Ces assemblages connus d'échangeurs primaires et secondaires présentent l'inconvénient de nécessiter des opérations coûteuses en temps et en outillage. These known assemblies of primary and secondary exchangers have the disadvantage of requiring operations costly in time and tools.

D'autre part, les organes de liaison entre les échangeurs principaux et secondaires occupent un certain volume qui nuit à la compacité du module. En effet, les boítes collectrices présentent une épaisseur importante. L'épaisseur du module n'est donc pas conditionnée par le cumul des épaisseurs des corps d'échangeurs, c'est-à-dire des assemblages de tubes, mais par le cumul des épaisseurs des boítes collectrices, notablement plus importantes.On the other hand, the connecting members between the exchangers main and secondary occupy a certain volume which harms the compactness of the module. In fact, the manifolds have a significant thickness. The thickness of the module is therefore not conditioned by the cumulative thicknesses of body of exchangers, i.e. tube assemblies, but by the cumulative thicknesses of the manifolds, significantly more important.

En outre, ces organes de liaison présentent un certain encombrement transversal et ne permettent donc pas de disposer de la même surface d'échange pour les échangeurs principaux et secondaires.In addition, these liaison bodies have a certain transverse dimensions and therefore do not allow have the same exchange surface for exchangers main and secondary.

La présente invention vise à pallier ces inconvénients.The present invention aims to overcome these drawbacks.

Plus particulièrement, l'invention a pour but de fournir un module d'échange de chaleur dont la réalisation, et notamment les opérations de montage, soit le plus simple possible.More particularly, the invention aims to provide a heat exchange module, the production of which, and in particular assembly operations, as simple as possible.

L'invention a également pour but de fournir un tel module d'échange de chaleur qui, dans la mesure du possible, ne comporte pas de pièces d'assemblage entre les échangeurs principaux et secondaires.The invention also aims to provide such a module heat exchange which, as far as possible, does not no assembly parts between the exchangers main and secondary.

L'invention vise en outre à fournir un procédé de réalisation d'un module d'échange de chaleur ne nécessitant pas d'opération d'assemblage ou, lorsque cela est impossible, en comportant un minimum.The invention further aims to provide a method of making a heat exchange module that does not require any operation assembly or, when this is not possible, by with a minimum.

L'invention a également pour but de fournir un tel module d'échange de chaleur de moindre épaisseur que ceux de l'art antérieur.The invention also aims to provide such a module heat exchange thinner than those of art prior.

L'invention a également pour but de fournir un module d'échange de chaleur présentant des caractéristiques d'échange thermique améliorées. The invention also aims to provide a module heat exchange with exchange characteristics thermal improvements.

À cet effet, l'invention a pour objet un module d'échange de chaleur, comprenant un échangeur principal et au moins un échangeur secondaire comportant chacun un corps muni de tubes de circulation de fluide, et des moyens d'encliquetage pour fixer l'échangeur secondaire sur l'échangeur principal de sorte qu'un même flux d'air puisse traverser les corps respectifs desdits échangeurs,
dans lequel lesdits moyens d'encliquetage comprennent au moins un organe en forme de peigne comportant :

  • des moyens de montage sur un premier desdits échangeurs, et
  • au moins une première rangée de dents présentant entre elles, deux par deux, un intervalle-de forme correspondant sensiblement à la section transversale des tubes de circulation de fluide du deuxième desdits échangeurs, de manière à encliqueter le corps de ce deuxième échangeur sur ledit organe en forme de peigne pour le fixer au premier échangeur.
    • To this end, the invention relates to a heat exchange module, comprising a main exchanger and at least one secondary exchanger each comprising a body provided with fluid circulation tubes, and latching means for fixing the secondary exchanger on the main exchanger so that the same air flow can pass through the respective bodies of said exchangers,
    wherein said latching means comprise at least one comb-shaped member comprising:
  • mounting means on a first of said exchangers, and
  • at least a first row of teeth having between them, two by two, a gap-shape corresponding substantially to the cross section of the fluid circulation tubes of the second of said exchangers, so as to snap the body of this second exchanger onto said member comb-shaped to fix it to the first exchanger.

    • Les échangeurs sont donc assemblés par leur corps, par l'intermédiaire de leurs tubes et des organes en forme de peigne.The exchangers are therefore assembled by their body, by through their tubes and shaped organs comb.

    Il en résulte une simplification du montage du module d'échange de chaleur.This results in a simplification of the assembly of the module. heat exchange.

    Le module peut en outre présenter des dimensions moins importantes. En effet, les organes en forme de peigne peuvent se situer entièrement dans l'espace entre les corps et ne débordent pas dans ce cas sur la section transversale des échangeurs. En outre, les corps peuvent être aussi rapprochés qu'on le souhaite.The module may also have dimensions less important. Indeed, the comb-shaped organs can be entirely in the space between the bodies and do not in this case do not extend beyond the cross section of the exchangers. In addition, the bodies can also be brought together as we wish.

    Il en résulte donc également une épaisseur inférieure pour le module, et une possibilité de disposer pour chaque échangeur d'une surface d'échange maximale. This therefore also results in a lower thickness for the module, and a possibility of having for each exchanger maximum exchange area.

    Dans un mode de réalisation particulier, lesdits moyens de montage de l'organe en forme de peigne sur le premier desdits échangeurs comprennent une deuxième rangée de dents présentant entre elles, deux par deux, un intervalle de forme correspondant sensiblement à la section transversale des tubes de circulation de fluide du premier desdits échangeurs, de manière à encliqueter ledit organe en forme de peigne sur le corps du premier échangeur.In a particular embodiment, said means of mounting of the comb-shaped member on the first of said exchangers include a second row of teeth with between them, two by two, a form interval substantially corresponding to the cross section of fluid circulation tubes of the first of said exchangers, so as to snap said comb-shaped member onto the body of the first exchanger.

    Dans un autre mode de réalisation particulier, lesdits moyens de montage de l'organe en forme de peigne sur le premier desdits échangeurs comprennent un ensemble de trous dans lesquels sont engagés les tubes de circulation de fluide du premier échangeur.In another particular embodiment, said means for mounting the comb-shaped member on the first said exchangers include a set of holes in which are engaged the fluid circulation tubes of the first exchanger.

    Ledit organe en forme de peigne peut comprendre une bande de support et des dents sensiblement dans le plan de la bande, le plan de cet organe se trouvant sensiblement perpendiculaire aux plans des corps des échangeurs.The comb-shaped member may include a strip of support and teeth substantially in the plane of the band, the plane of this organ being substantially perpendicular to the plans of the exchanger bodies.

    En variante, ledit organe en forme de peigne peut comprendre une bande de support et des dents dans un plan sensiblement perpendiculaire au plan de la bande, le plan de la bande se trouvant sensiblement parallèle aux plans des corps des échangeurs.Alternatively, said comb-shaped member may include a support strip and teeth in a plane substantially perpendicular to the plane of the strip, the plane of the strip is finding substantially parallel to the planes of the bodies of exchangers.

    Plus particulièrement, le module d'échange de chaleur selon l'invention peut comprendre au moins deux organes en forme de peigne, lesdits organes appartenant à deux côtés d'un cadre de montage agencé pour recevoir lesdits échangeurs de chaleur par l'intermédiaire des organes en forme de peigne.More specifically, the heat exchange module according to the invention may include at least two organs in the form of comb, said organs belonging to two sides of a frame assembly arranged to receive said heat exchangers through comb-shaped organs.

    Encore plus particulièrement, le module d'échange de chaleur selon l'invention peut comporter un cadre tubulaire avec deux organes en forme de peigne dont les bandes de support sont disposées à l'intérieur du cadre, le long de deux côtés opposés de ce dernier, dans une partie médiane de ces côtés dans le sens axial. Even more particularly, the heat exchange module according to the invention may include a tubular frame with two comb-shaped members whose support bands are arranged inside the frame, along two sides opposite of the latter, in a middle part of these sides in the axial direction.

    Dans un mode de réalisation particulier, l'organe en forme de peigne présente un décrochement, de préférence sensiblement parallèle au plan des échangeurs, entre les moyens de montage sur le premier échangeur et la première rangée de dents.In a particular embodiment, the member in the form of comb has a recess, preferably substantially parallel to the exchanger plane, between the mounting means on the first exchanger and the first row of teeth.

    Le décrochement peut s'étendre sur toute la longueur de l'organe en forme de peigne ou uniquement aux extrémités de ce dernier.The recess can extend over the entire length of the comb-shaped organ or only at the ends of this last.

    Cet agencement permet d'assembler des échangeurs de dimensions différentes.This arrangement makes it possible to assemble exchangers of dimensions different.

    L'invention a également pour objet un procédé de réalisation d'un module d'échange de chaleur comprenant un échangeur principal et au moins un échangeur secondaire comportant chacun un corps muni de tubes de circulation de fluide, et des moyens d'encliquetage pour fixer l'échangeur secondaire sur l'échangeur principal de sorte qu'un même flux d'air puisse traverser les corps respectifs desdits échangeurs,
    ce procédé comprenant les étapes consistant à :

  • réaliser lesdits échangeurs,
  • réaliser au moins un organe en forme de peigne comportant des moyens de montage sur un premier desdits échangeurs, et au moins une première rangée de dents présentant entre elles, deux par deux, un intervalle de forme correspondant sensiblement à la section transversale des tubes de circulation de fluide du deuxième desdits échangeurs,

    On voit à la figure 1 un module d'échange de chaleur comprenant deux échangeurs de chaleur, à savoir un radiateur 1 de refroidissement d'un moteur de véhicule automobile muni de son groupe moto-ventilateur 2, et un condenseur 3 de climatisation.We see in Figure 1 a heat exchange module comprising two heat exchangers, namely a radiator 1 of cooling of a motor vehicle engine provided with its motor-fan unit 2, and an air conditioning condenser 3.

    Le radiateur 1 est constitué de façon connue d'un corps 4 monté entre deux boítes collectrices 5 et 6, la boíte collectrice 6 étant munie de tubulures 7 d'entrée et de sortie de fluide de refroidissement.The radiator 1 consists in a known manner of a body 4 mounted between two manifolds 5 and 6, the box manifold 6 being provided with inlet pipes 7 and coolant outlet.

    Le corps 4 est réalisé à partir d'un faisceau de tubes horizontaux 8 de circulation de fluide (figure 4), non représentés individuellement à la figure 1. Ces tubes sont ici des tubes à section circulaire répartis sur deux nappes perpendiculaires à la direction d'avance AV du véhicule.The body 4 is produced from a bundle of tubes horizontal 8 for fluid circulation (figure 4), not shown individually in Figure 1. These tubes are here circular section tubes distributed on two layers perpendicular to the vehicle's AV direction of travel.

    Le condenseur 3 est également constitué d'un corps 9 monté entre deux boítes collectrices 10 et 11, la boíte collectrice 10 étant munie de tubulures 12 d'entrée et de sortie de fluide.The condenser 3 also consists of a body 9 mounted between two manifolds 10 and 11, the manifold 10 being provided with inlet and outlet pipes 12 fluid.

    Le corps 9 est réalisé à partir d'un faisceau de tubes de circulation de fluide horizontaux 13 (figure 4). Les tubes 13 sont des tubes plats cloisonnés intérieurement, encore appelés tubes multi-canaux, dont le plan est disposé parallèlement à la direction d'avance AV du véhicule. Ces tubes 13 sont répartis sur une seule nappe perpendiculaire à la direction AV.The body 9 is produced from a bundle of tubes of horizontal fluid circulation 13 (Figure 4). Tubes 13 are internally partitioned flat tubes, again called multi-channel tubes, the plane of which is arranged parallel to the AV advance direction of the vehicle. These tubes 13 are distributed on a single tablecloth perpendicular to the direction AV.

    On va voir ci-après que les échangeurs de chaleur 1 et 3 sont assemblés par leur corps 4 et 9 respectivement, par l'intermédiaire de deux organes 14 en forme de peignes, dont un tronçon est représenté en détail à la figure 3. We will see below that the heat exchangers 1 and 3 are assembled by their bodies 4 and 9 respectively, via of two comb-shaped members 14, one of which section is shown in detail in Figure 3.

    Chaque organe 14 possède une forme plane généralement allongée, avec une bande centrale pleine 15 munie le long de chacun de ses grands côtés d'une rangée de couple de dents, 16, 17 respectivement, formant donc deux peignes opposés dans le plan de la bande 15.Each member 14 has a generally planar shape elongated, with a solid central strip 15 provided along each of its long sides of a row of couple of teeth, 16, 17 respectively, thus forming two opposite combs in the plan of the strip 15.

    Les couples de dents 16 sont espacés au pas transversal des tubes 8, et forment entre ces dents une fente 18 de largeur légèrement inférieure au diamètre des tubes 8. Cette fente comporte deux zones élargies, l'une 19 de fond de fente, et l'autre 20 proche du bord de la fente.The pairs of teeth 16 are spaced at the transverse pitch of the tubes 8, and form between these teeth a slot 18 of width slightly smaller than the diameter of the tubes 8. This slot has two enlarged zones, one 19 at the bottom of the slot, and the other 20 near the edge of the slot.

    Les zones élargies 19 et 20 ont une forme généralement circulaire d'un diamètre sensiblement égal à celui des tubes 8. Leurs centres sont espacés le long de la fente 18 d'une distance sensiblement égale à la distance séparant les deux nappes de tubes 8.The enlarged zones 19 and 20 generally have a shape circular with a diameter substantially equal to that of the tubes 8. Their centers are spaced along slot 18 of a distance substantially equal to the distance between the two tube sheets 8.

    Les couples de dents 17 sont espacés au pas transversal des tubes 13, et forment entre ces dents une fente 21 d'une profondeur sensiblement égale à la largeur des tubes 13 et d'une largeur sensiblement égale à l'épaisseur de ces tubes.The pairs of teeth 17 are spaced at the transverse pitch of the tubes 13, and form between these teeth a slot 21 of a depth substantially equal to the width of the tubes 13 and of a width substantially equal to the thickness of these tubes.

    Chaque fente 21 possède un fond arrondi et est partiellement fermée par un bec de maintien 22 en saillie à l'extrémité de chaque dent vers l'intérieur de la fente.Each slot 21 has a rounded bottom and is partially closed by a retaining spout 22 projecting from the end of each tooth inward of the slot.

    Les organes 14 sont réalisés par exemple en matière plastique, et sont coupés à la demande en fonction de la hauteur du module d'échange de chaleur. Comme montré à la figure 4, chaque organe est encliqueté en premier lieu par exemple sur les tubes 8 de l'échangeur 1 par ses dents 16, puis les tubes 13 de l'échangeur 3 sont encliquetés sur les dents 17 de l'organe 14 pour assurer l'assemblage du module.The members 14 are made for example of plastic, and are cut on demand according to the height of the heat exchange module. As shown in Figure 4, each organ is snapped in the first place for example on the tubes 8 of the exchanger 1 by its teeth 16, then the tubes 13 of the exchanger 3 are snapped onto the teeth 17 of the member 14 for assembling the module.

    Le plan de chaque organe 14 se trouve donc, dans le présent mode de réalisation, sensiblement perpendiculaire aux plans des nappes de tubes 8 et 13. Les bandes 15 de chaque organe 14 assurent la fonction d'étanchéité latérale pour l'écoulement de l'air entre les deux échangeurs.The plane of each organ 14 is therefore, in the present embodiment, substantially perpendicular to the planes plies of tubes 8 and 13. The bands 15 of each member 14 provide lateral sealing function for flow air between the two exchangers.

    La figure 2 présente une variante dans laquelle les dents d'encliquetage 23 pour encliqueter l'échangeur 1, et 24 pour encliqueter l'échangeur 3, sont montées sur un cadre 25.Figure 2 shows a variant in which the teeth 23 to engage the exchanger 1, and 24 to snap on the exchanger 3, are mounted on a frame 25.

    Le cadre 25 présente, dans la direction de la flèche AV, une forme généralement tubulaire à section rectangulaire, de dimensions légèrement supérieures aux dimensions en plan des échangeurs de chaleur 1 et 3.The frame 25 has, in the direction of the arrow AV, a generally tubular shape with rectangular section, of dimensions slightly greater than the plan dimensions of heat exchangers 1 and 3.

    Dans la zone axialement médiane du cadre 25, deux bandes 26 sont fixées aux côtés opposés verticaux de ce cadre, en saillie vers l'intérieur de ce dernier, donc sensiblement perpendiculairement à la direction de la flèche AV. Les dents d'encliquetage 23 et 24 sont disposées le long du bord intérieur des bandes 26, perpendiculairement au plan de ces bandes, en saillie par conséquent dans la direction de la flèche AV.In the axially middle zone of the frame 25, two bands 26 are attached to the opposite vertical sides of this frame, protruding towards the inside of the latter, therefore substantially perpendicular to the direction of the arrow AV. The teeth latching 23 and 24 are arranged along the edge inside of the bands 26, perpendicular to the plane of these strips, therefore protruding in the direction of the arrow AV.

    La forme et le pas des dents 23 sont identiques à ceux des dents 16, de même que la forme et le pas des dents 24 sont identiques à ceux des dents 17.The shape and pitch of the teeth 23 are identical to those of the teeth 16, as well as the shape and pitch of teeth 24 are identical to those of teeth 17.

    L'assemblage du module d'échange de chaleur se fait alors en encliquetant successivement les tubes 8 de l'échangeur 1 et 13 de l'échangeur 3 sur le cadre 25, par l'intermédiaire des dents 23 et 24 respectivement.The assembly of the heat exchange module is then done by successively engaging the tubes 8 of the exchanger 1 and 13 of the exchanger 3 on the frame 25, via the teeth 23 and 24 respectively.

    Dans ce cas, l'étanchéité latérale entre les deux échangeurs est assurée par le cadre 25 qui forme une buse de circulation d'air dans laquelle sont interposés les deux échangeurs.In this case, the lateral seal between the two exchangers is provided by the frame 25 which forms a circulation nozzle of air in which the two exchangers are interposed.

    Le cadre tubulaire 25 peut présenter axialement, c'est-à-dire dans la direction de la flèche AV, une dimension sensiblement égale à l'épaisseur du module, qu'il enveloppe donc sensiblement totalement. The tubular frame 25 can have axially, that is to say in the direction of the arrow AV, a dimension substantially equal to the thickness of the module, which it therefore substantially envelops totally.

    Un autre mode de réalisation est représenté aux figures 5 et 6.Another embodiment is shown in Figures 5 and 6.

    L'organe en forme de peigne 27 (figure 5) comporte toujours une bande centrale pleine 28 mais, si l'un des bords longitudinaux de cette bande est toujours muni de couples de dents 29 pour l'encliquetage des tubes de l'un des échangeurs de chaleur, son autre bord comporte des trous 30 de forme et de dimensions correspondant aux tubes de l'autre échangeur de chaleur. Dans le cas présent, les deux échangeurs (figure 6) sont des échangeurs à une nappe de tubes platsThe comb-shaped member 27 (FIG. 5) always includes a solid central strip 28 but, if one of the longitudinal edges of this band is always provided with pairs of teeth 29 for the locking of the tubes of one of the heat exchangers heat, its other edge has holes 30 of shape and dimensions corresponding to the tubes of the other heat exchanger heat. In this case, the two exchangers (Figure 6) are single-ply exchangers of flat tubes

    L'assemblage du module d'échange de chaleur s'effectue alors en incluant les organes 27 lors de la réalisation de l'échangeurcorrespondant aux trous 30. Le deuxième échangeur est ensuite encliqueté sur les dents 29.The heat exchange module is then assembled by including the members 27 during the production of the corresponding exchanger at holes 30. The second exchanger is then snapped onto teeth 29.

    On observera que ce mode de réalisation permet l'assemblage de trois échangeurs de chaleur, en prévoyant une deuxième rangée de dents de l'autre côté des trous 30, le long du bord de l'organe 27 opposé aux dents 29.It will be observed that this embodiment allows assembly three heat exchangers, providing a second row of teeth on the other side of the holes 30, along the edge of the member 27 opposite the teeth 29.

    On voit aux figures 7 et 8 les deux échangeurs 1 et 3 de dimensions différentes et assemblés à l'aide d'un organe en forme de peigne 31 comportant, comme décrit précédemment, des trous 32 pour le passage des tubes de l'échangeur 1 et des dents 33 pour la réception des tubes de l'échangeur 3.FIGS. 7 and 8 show the two exchangers 1 and 3 of different dimensions and assembled using a comb shape 31 comprising, as described above, holes 32 for the passage of the exchanger 1 tubes and teeth 33 for receiving the tubes of the exchanger 3.

    Dans le cas présent, toutefois, l'organe en forme de peigne 31 comporte un décrochement 34 sensiblement perpendiculaire aux plans dudit organe dans lesquels sont formés les trous 32 et les dents 33, décrochement situé entre le plan dans lequel sont formés les trous 32 et le plan dans lequel sont formées les dents 33, et qui se trouve donc après montage sensiblement parallèle aux plans des échangeurs 1 et 3.In this case, however, the comb-shaped organ 31 has a substantially perpendicular recess 34 to the planes of said member in which the holes 32 are formed and the teeth 33, recess situated between the plane in which are formed the holes 32 and the plane in which are formed teeth 33, and which is therefore after mounting substantially parallel to the plans of exchangers 1 and 3.

    Le décrochement 34 est ici réalisé en deux parties aux extrémités de l'organe en forme de peigne 31. Les dents 33 qui sont reliées à ce décrochement ne figurent donc que dans ces parties d'extrémité.The recess 34 is here carried out in two parts at the ends of the comb-shaped member 31. The teeth 33 which are linked to this setback therefore only appear in these end parts.

    La figure 9 montre un organe en forme de peigne 35 qui est une variante de réalisation de l'organe en forme de peigne 31 des figures 7 et 8. Les mêmes références ont été utilisées.Figure 9 shows a comb-shaped member 35 which is an alternative embodiment of the comb-shaped member 31 Figures 7 and 8. The same references have been used.

    Cependant, dans ce dernier cas, le décrochement 34 s'étend sur toute la longueur de l'organe en forme de peigne 35, de même par conséquent que les dents 33. En outre les trous de passage des tubes de l'échangeur 1 ont été remplacés par des dents 36.However, in the latter case, the recess 34 extends over the entire length of the comb-shaped member 35, same therefore as the teeth 33. Furthermore the holes of passage of the heat exchanger tubes 1 have been replaced by teeth 36.

    On observera que, dans le cas des dents, on prévoit dans les organes en forme de peigne 31 et 35 des crochets d'extrémité 37, en prolongement des dents 33, qui permettent d'assurer ou de renforcer l'encliquetage de l'organe en forme de peigne sur l'échangeur respectif.It will be observed that, in the case of teeth, provision is made in the comb-shaped members 31 and 35 of the end hooks 37, in extension of the teeth 33, which ensure or to strengthen the snap of the comb-shaped organ on the respective exchanger.

    Les modules d'échange de chaleur des figures 7 à 9 peuvent comporter un ou deux organes en forme de peigne tels que ceux qui viennent d'être décrits, à une ou chacune de leurs extrémités.The heat exchange modules in Figures 7 to 9 can have one or two comb-shaped members such as those which have just been described, to one or each of their extremities.

    La présence d'un décrochement entre les moyens de montage (dents ou trous) sur le premier échangeur et les dents pour l'encliquetage du deuxième échangeur permettent d'assembler deux échangeurs de dimensions différentes. Autrement dit, ce décrochement permet l'assemblage de deux échangeurs dont les corps respectifs, c'est à dire leurs tubes respectifs, ont des longueurs différentes.The presence of a setback between the mounting means (teeth or holes) on the first exchanger and the teeth for the snap-in of the second exchanger allows assembly two exchangers of different dimensions. In other words, this offset allows the assembly of two exchangers whose respective bodies, i.e. their respective tubes, have different lengths.

    Bien entendu, le décrochement peut être réalisé sur toute la longueur de l'organe en forme de peigne ou seulement aux extrémités de ce dernier, quel que soit le type des moyens de montage (dents ou trous) utilisés pour l'assemblage du premier échangeur.Of course, the setback can be achieved over the entire length of the comb-shaped organ or only at the ends of the latter regardless of the type of means of mounting (teeth or holes) used for assembling the first exchanger.
