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 heat exchange module comprising a main exchanger and at least one secondary exchanger each comprising a body fitted with fluid circulation tubes, and snap-fastening means for fixing the secondary exchanger onto the exchanger main so that the same airflow can pass through the respective bodies of the said exchangers. US-A-3 938 587 montre un tel échangeur de chaleur. US-A-3,938,587 shows such a heat exchanger.

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. Such exchangers are generally in the form of a body provided with fluid flow tubes and heat exchange fins with the external environment. Ce corps est disposé entre deux boítes collectrices qui distribuent le fluide dans les tubes de circulation. This body is arranged between two manifolds which distribute the fluid in the flow 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. It is known to assemble a main exchanger, such as a radiator for cooling a motor vehicle engine, one or more secondary exchangers to form a set, also called module, ready to be installed in the vehicle. Cet échangeur secondaire est constitué le plus souvent d'un refroidisseur d'air de suralimentation du moteur ou d'un condenseur de climatisation. This secondary exchanger consists most often of a supercharging air cooler 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. The assembly of the secondary exchanger onto the main exchanger is generally obtained by means of lugs integral with the secondary exchanger and screws inserted into the header boxes of the main exchanger. On a également proposé des systèmes d'assemblage par emboítement ou encliquetage des boítes collectrices. assembly systems have also been proposed by interlocking or snap-fitting of 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 heat exchangers have the disadvantage of requiring costly in time and equipment.

D'autre part, les organes de liaison entre les échangeurs principaux et secondaires occupent un certain volume qui nuit à la compacité du module. On the other hand, the connecting members between the main and secondary exchangers occupy a volume that affects the compactness of the module. En effet, les boítes collectrices présentent une épaisseur importante. Indeed, the manifolds have a large thickness. 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. The thickness of the module is thus not influenced by the accumulated thicknesses of the exchanger bodies, that is to say, tube assemblies, but by the accumulated 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 connecting members have a transverse size and therefore do not have the same exchange area for the primary and secondary heat exchangers.

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

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 whose implementation, including assembly operations, or 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 heat exchange module which, as far as possible, has no connecting pieces between the primary and secondary heat exchangers.

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 process for producing a heat exchange module requiring no assembly operation or, where this is impossible, comprising 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 heat exchange module of lesser thickness than those of the prior art.

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 heat exchange module having improved heat transfer characteristics.

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, 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 fitted with fluid circulation tubes, and latching means for securing the secondary exchanger onto the main exchanger so that the same airflow can pass through the respective bodies of the said exchangers,
dans lequel lesdits moyens d'encliquetage comprennent au moins un organe en forme de peigne comportant : wherein said latching means comprise at least one comb-shaped member comprising:

  • des moyens de montage sur un premier desdits échangeurs, et mounting means on a first of the said exchangers, and
  • 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. at least a first row of teeth having between them, two by two, a form of time corresponding substantially to the cross section of the fluid circulation tubes of the second of the said exchangers so as to snap-fasten the body of this second exchanger onto the said member in comb to secure 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. Exchangers are therefore assembled by their bodies through their tubes and comb-like members.

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

Le module peut en outre présenter des dimensions moins importantes. The module can also present smaller dimensions. 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. Indeed, the comb-shaped bodies can be located entirely within the space between the body and do not exceed in this case the cross section of the exchangers. En outre, les corps peuvent être aussi rapprochés qu'on le souhaite. In addition, the body can also be pushed together as desired.

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 smaller thickness for the module, and a possibility to have for each exchanger with a maximum exchange surface.

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 for mounting the comb-shaped member on the first of the said exchangers comprise a second row of teeth having between them, in pairs, form an interval substantially corresponding to the cross section of the tubes fluid flow of the first of the said exchangers, so as to snap-fasten the said comb-shaped member on 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 of the said exchangers comprise a set of holes in which are engaged 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. Said comb-shaped member may include a support strip and teeth substantially in the plane of the strip, the plane of this member lying substantially perpendicular to the planes of the bodies of the exchangers.

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 lying substantially parallel to the planes of the bodies of the 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 particularly, the heat exchange module according to the invention may comprise at least two comb-like members, said members belonging to two sides of a mounting frame arranged to receive said heat exchangers via the bodies comb.

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 comprise a tubular frame with two comb-like members of which the support strips are disposed within the frame, along two opposite sides thereof in a central 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 comb-shaped member has a recess, preferably substantially parallel to the plane of the exchangers, 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 may extend over the entire length of the comb-shaped member, or only at the ends of the latter.

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

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, The invention also relates to a method of producing a heat exchange module comprising a main exchanger and at least one secondary exchanger each comprising a body fitted with fluid circulation tubes, and snap-fastening means for securing the secondary exchanger onto the main exchanger so that the same airflow can pass through the respective bodies of the said exchangers,
ce procédé comprenant les étapes consistant à : said method comprising the steps of:

  • réaliser lesdits échangeurs, making said exchangers,
  • 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, providing at least one comb-shaped member having mounting means on a first of the said exchangers, and at least a first row of teeth having between them, two by two, matching a shape gap substantially to the cross section of said flow tubes fluid of the second of the said exchangers,
  • monter ledit organe en forme de peigne sur le premier échangeur, et mounting said comb-shaped member on the first exchanger, and
  • encliqueter le corps du deuxième échangeur sur ledit organe en forme de peigne. snapping the body of the second exchanger onto the said comb-shaped member.

Dans un premier mode de mise en oeuvre du procédé selon l'invention, ledit organe en forme de peigne est monté sur le premier échangeur lors de la réalisation de ce dernier. In a first implementation of the method according to the invention, said comb-shaped member is mounted on the first exchanger during the production of the latter.

Dans un autre mode de mise en oeuvre, ledit organe en forme de peigne est encliqueté sur le corps du premier échangeur après la réalisation de ce dernier. In another mode of implementation, said comb-shaped member is snapped on the body of the first exchanger after the completion of the latter.

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. Seen in Figure 1 a heat exchange module comprising two heat exchangers, namely a radiator 1 for cooling a motor vehicle engine provided with a motor fan unit 2, a condenser 3 and air conditioning.

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 comprises in known manner a body 4 mounted between two header tanks 5 and 6, the collecting box 6 being provided with nozzles 7 inlet and cooling fluid 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 horizontal tubes 8 of fluid flow (figure 4), not shown individually in Figure 1. These tubes are here of circular cross-section tubes distributed over two webs perpendicular to the direction AV ahead of the vehicle.

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 is also constituted by a body 9 mounted between two manifolds 10 and 11, the collecting box 10 being provided with nozzles 12 inlet and fluid outlet.

Le corps 9 est réalisé à partir d'un faisceau de tubes de circulation de fluide horizontaux 13 (figure 4). The body 9 is made of a bundle of horizontal fluid flow tubes 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. The tubes 13 are flat tubes partitioned internally, also called multi-channel tubes, whose plane is arranged parallel to the AV running direction of the vehicle. Ces tubes 13 sont répartis sur une seule nappe perpendiculaire à la direction AV. These tubes 13 are distributed on a single sheet 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 with their bodies 4 and 9 respectively, by means of two bodies 14 in the form of combs, a portion of which 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 planar shape generally elongate, with a solid central strip 15 provided along each of its longitudinal sides with a row of pair of teeth 16, 17 respectively, thus forming two opposite combs in the plane of the web 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 track pitch of the tubes 8, and between these teeth form a slot 18 slightly narrower than the diameter of the tubes 8. This slot has two enlarged areas, one 19 of slot bottom, and 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 expanded areas 19 and 20 have a generally circular shape with a diameter substantially equal to that of the tubes 8. Their centers are spaced along the slot 18 a distance substantially equal to the distance separating the two rows of tubes 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 not spaced transverse tubes 13, and between these teeth form a slit 21 of a depth substantially equal to the width of 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 spout 22 projecting holding at the end of each tooth towards the inside 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. The members 14 are made for example of plastic, and are cut to the request based on the height of the heat exchange module. 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. As shown in Figure 4, each member is latched in the first place for example on the tubes 8 of the exchanger 1 by its teeth 16 and the tubes 13 of the exchanger 3 are snapped onto the teeth 17 of the member 14 in order to assemble 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 member 14 is thus, in this embodiment, substantially perpendicular to the layers of tubes of the planes 8 and 13. The strips 15 of each member 14 provide lateral sealing function for the flow of the 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. 2 shows a variant in which the ratchet teeth 23 for locking the exchanger 1, and 24 for snapping 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 arrow AV, a generally tubular shape with a rectangular section, of slightly greater dimensions in plan dimensions of the 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. In the axially central region of the frame 25, two strips 26 are fixed to the vertical opposite sides of said frame, projecting inwardly of the latter, thus substantially perpendicular to the direction of arrow 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. The ratchet teeth 23 and 24 are disposed along the inner edge of the strips 26 perpendicular to the plane of these bands projecting therefore in the direction of 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 the pitch of the teeth 23 are identical to those of the teeth 16, as well as the shape and pitch of the teeth 24 are identical to those of the 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 dès dents 23 et 24 respectivement. The assembly of the heat exchange module is then snapping successively the tubes 8 of the heat exchanger 1 and 13 of the heat exchanger 3 on the frame 25 through 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 sealing between the two exchangers is ensured by the frame 25 which forms an air flow nozzle 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 may have axially, that is to say in the direction of arrow AV, a dimension substantially equal to the thickness of the module, so that casing substantially completely.

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. The comb-shaped member 27 (Figure 5) always has a solid central strip 28, but if one of the longitudinal edges of the strip is always provided with pairs of teeth 29 for locking the tubes of one of the heat exchangers, the other edge is provided with holes 30 of form and dimensions corresponding to the tubes of the other heat exchanger. Dans le cas présent, les deux échangeurs (figure 6) sont des échangeurs à une nappe de tubes plats In this case, the two exchangers (6) are heat exchangers of one sheet 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'échangeur correspondant aux trous 30. Le deuxième échangeur est ensuite encliqueté sur les dents 29. The assembly of the heat exchange module is then carried out including the elements 27 during the production of the exchanger corresponding to the holes 30. The second heat exchanger is then snapped onto the 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 the assembly of three heat exchangers, by providing a second row of teeth on the other side of the holes 30 along the edge of the member 27 opposite to 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. It is seen in Figures 7 and 8 the two exchangers 1 and 3 of different sizes and assembled by means of a comb-shaped member 31 having, as previously described, holes 32 for the passage of tubes of the exchanger 1 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 member 31 has a shoulder 34 substantially perpendicular to the planes of said body in which are formed holes 32 and teeth 33, recess located between the plane in which are formed holes 32 and the plane in which are formed the teeth 33, and which is thus substantially parallel after assembly to the planes of the 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 step 34 is here made in two parts at the ends of the comb-shaped member 31. The teeth 33 which are connected to this offset therefore appear only in these end portions.

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. 9 shows a comb-shaped member 35 which is an alternative embodiment of the comb-shaped member 31 of Figures 7 and 8. The same reference numerals were 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 body-shaped comb 35, and therefore the teeth 33. In addition, the passage holes of the exchanger 1 of tubes 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, is provided in the organs comb 31 and 35 of the end brackets 37, an extension of the teeth 33, which ensure or enhance the locking of the body comb-shaped 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 of Figures 7 to 9 may comprise one or two comb-like members such as those just described, with one or each of their ends.

La présence d'un décrochement entre les moyens. The presence of a step between the means. 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. mounting (teeth or holes) on the first exchanger and the teeth for latching the second exchanger make it possible to assemble two exchangers of different dimensions. 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. In other words, this offset allows the assembly of two exchangers, the respective body, that is to say 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 shoulder can be carried out over the entire length of the comb-shaped member or only at the ends of the latter, regardless of the type of mounting means (teeth or holes) used for the assembly of the first exchanger .
