Description

Echangeur de chaleur comportant au moins une bride pour un collecteur de cet échangeur ainsi qu'un réservoir destiné à équiper un tel échangeurHeat exchanger comprising at least one flange for a collector of this exchanger and a reservoir intended to equip such an exchanger
L'invention concerne un échangeur de chaleur, en particulier un condenseur d'une installation de climatisation de véhicule automobile ainsi qu'un réservoir destiné à équiper un tel échangeur.The invention relates to a heat exchanger, in particular a condenser of a motor vehicle air-conditioning installation and a reservoir intended to equip such an exchanger.
Elle concerne plus particulièrement un échangeur de chaleur propre à être traversé par un fluide, comportant au moins une bride reliée à un collecteur de l'échangeur, ainsi qu'un faisceau pour transporter le fluide, relié au collecteur et s'étendant dans un plan.It relates more particularly to a heat exchanger adapted to be traversed by a fluid, comprising at least one flange connected to a collector of the exchanger, and a beam for conveying the fluid, connected to the collector and extending in a plane. .
On connaît déjà des brides de ce type utilisées en particulier pour raccorder les tubulures d'entrée et/ou de sortie à au moins un collecteur d'un condenseur dans un circuit faisant partie d'une installation de climatisation pour véhicule automobile.Flanges of this type are already known, used in particular for connecting the inlet and / or outlet pipes to at least one collector of a condenser in a circuit forming part of an air-conditioning installation for a motor vehicle.
On sait qu'une installation de climatisation comprend un compresseur, un condenseur, un détendeur et un évaporâteur parcourus, dans cet ordre, par un fluide réfrigérant.It is known that an air conditioning installation comprises a compressor, a condenser, an expander and an evaporator traveled in this order by a refrigerant.
Généralement, le condenseur est placé à l'avant du véhicule, c'est-à-dire en avant du radiateur de refroidissement du moteur thermique, et il est muni d'au moins un collecteur relié d'une part à des tubulures d'entrée et de sortie du fluide dans le condenseur, et d'autre part, à un faisceau de 1'échangeur de chaleur.Generally, the condenser is placed at the front of the vehicle, that is to say in front of the cooling radiator of the heat engine, and it is provided with at least one manifold connected on the one hand to tubings of inlet and outlet of the fluid in the condenser, and secondly, to a beam of the heat exchanger.
La bride permet alors de raccorder le collecteur à la tubulure d'entrée et de sortie, l'une servant à l'amenée du fluide réfrigérant gazeux provenant du compresseur et l'autre servant à l'évacuation du fluide réfrigérant condensé vers le détendeur, lesdites tubulures étant munies de moyens d'accrochage complémentaires à ceux prévus sur la bride.The flange then makes it possible to connect the manifold to the inlet and outlet pipe, one serving for supplying the gaseous cooling fluid from the compressor and the other for discharging condensed refrigerant towards the expander, said manifolds being provided with attachment means complementary to those provided on the flange.
Dans les dispositifs connus, la bride est obtenue soit par matriçage puis usinage, soit par extrusion puis usinage ou tout autre procédé d'élaboration, la bride étant alors brasée sur le collecteur.In the known devices, the flange is obtained either by stamping and then machining, or by extrusion and machining or any other manufacturing method, the flange then being brazed to the collector.
De manière classique, la bride est positionnée sur le collecteur dans le plan du faisceau, c'est-à-dire qu'un axe de connexion que présente 1 'ouverture de connexion de la bride forme un angle nul ou très faible avec le plan du faisceau. Pour des raisons pratiques d'encombrement et pour d'autres, la position de la bride sur le collecteur peut devoir être différente, c'est-à-dire que l'angle de l'axe de connexion avec le plan du faisceau peut devoir être non nul.Conventionally, the flange is positioned on the collector in the plane of the beam, that is to say that a connection axis that has 1 connection opening of the flange forms a zero or very low angle with the plane beam. For practical reasons of space and for others, the position of the flange on the manifold may have to be different, that is to say that the angle of the connection axis with the plane of the beam may have to be different. to be non-zero.
Pour répondre à cette exigence, tout en satisfaisant les contraintes liées au brasage de la bride sur le collecteur, il est prévu des brides coudées dites "à 90°" .To meet this requirement, while satisfying the constraints related to the brazing of the flange on the manifold, it is provided bent flanges said "90 °".
De telles brides sont toutefois lourdes et de fabrication complexe.Such flanges, however, are heavy and complex in manufacture.
L'invention a notamment pour but d'améliorer la situation.The purpose of the invention is in particular to improve the situation.
Elle propose à cet effet un échangeur de chaleur propre à être traversé par un fluide, comportant au moins une bride reliée à une boîte collectrice de l'échangeur, ainsi qu'un faisceau pour transporter le fluide, relié à la boîte collectrice. La boîte collectrice comporte deux parties reliées par des bords des deux parties, et la bride est reliée à la boîte collectrice dans la région de liaison de ces deux parties. Avantageusement, le faisceau s'étend dans un plan, et l'ouverture de connexion présente un axe de connexion formant un angle sensiblement non nul avec le plan du faisceau.It proposes for this purpose a heat exchanger capable of being traversed by a fluid, comprising at least one flange connected to a manifold of the exchanger, and a beam for transporting the fluid, connected to the manifold. The manifold has two parts connected by edges of the two parts, and the flange is connected to the manifold in the connection region of these two parts. Advantageously, the beam extends in a plane, and the connection opening has an axis of connection forming a substantially non-zero angle with the plane of the beam.
Un tel échangeur offre l'avantage d'utiliser une bride sensiblement similaire aux brides droites classiques. Cela signifie à la fois une réduction des coûts et une réduction de 1 'encombrement. Cela permet de conserver la technologie de brasage classique pour relier la bride au collecteur sans néanmoins devoir utiliser une pièce spécialement prévue.Such an exchanger has the advantage of using a flange substantially similar to conventional straight flanges. This means both cost savings and reduced congestion. This makes it possible to keep the conventional brazing technology to connect the flange to the collector without having to use a specially designed part.
Avantageusement un bord d'une au moins des deux parties présente une ouverture de réception de la bride.Advantageously, an edge of at least one of the two parts has an opening for receiving the flange.
On peut prévoir que le bord de la partie qui présente l'ouverture de réception est en retrait par rapport au bord correspondant de l'autre partie, ce dernier le recouvrant dans la région de liaison et que les deux parties sont des coquilles ayant un profil sensiblement semi-circulaire, dont l'une des deux est prolongée par deux bords pinces.It can be provided that the edge of the part that has the receiving opening is set back relative to the corresponding edge of the other part, the latter covering it in the connection region and that the two parts are shells having a profile. substantially semicircular, one of which is extended by two edges clamps.
De manière avantageuse, une face de la bride comporte une saillie agencée pour être logée dans l'ouverture de réception de la boîte collectrice, laquelle saillie a une forme permettant le blocage en position de la bride au niveau de cette ouverture de réception avant brasage.Advantageously, a face of the flange has a projection arranged to be housed in the receiving opening of the manifold, which projection has a shape for locking in position of the flange at the receiving opening before soldering.
Avantageusement, la bride a une forme complémentaire de celle de la boîte collectrice dans la région de l'ouverture de connexion. Cela facilite l'étanchéité de l'ensemble.Advantageously, the flange has a shape complementary to that of the manifold in the region of the connection opening. This facilitates the sealing of the assembly.
Selon un premier mode de réalisation, ladite bride est une bride d'entrée/sortie de fluide et comporte une ouverture de connexion. La boîte collectrice comporte alors une ouverture de transfert en regard de laquelle est placée l'ouverture de connexion de la bride. On peut alors prévoir que la saillie présente un enfoncement, de sorte qu'elle correspond exacte¬ ment à la portion de la boîte collectrice qui a été découpée pour former l'ouverture de réception. Ainsi, le fluide pénétrant ou sortant de la boîte collectrice ne voit pas son écoulement être perturbé.According to a first embodiment, said flange is a fluid inlet / outlet flange and comprises a connection opening. The manifold then has a transfer opening opposite which is placed the connection opening of the flange. It can then be provided that the projection has a depression, so that it corresponds exactly¬ to the portion of the header that has been cut to form the receiving opening. Thus, the fluid entering or leaving the header box does not see its flow be disturbed.
Dans une variante, l'angle de connexion est droit et l'ouverture de transfert est incluse dans l'ouverture de réception, la saillie présentant une découpe pour préserver l'ouverture de transfert. Ces dispositions permettent d'économiser de la place.In a variant, the connection angle is straight and the transfer opening is included in the receiving opening, the projection having a cutout to preserve the transfer opening. These arrangements save space.

On a représenté sur la figure 1 un échangeur de chaleur selonFIG. 1 shows a heat exchanger according to
1 ' invention comportant un faisceau de tubes plats intercalés entre deux boîtes collectrices. Cet échangeur est un conden- seur pour circuit de climatisation d'un véhicule automobile.The invention comprising a bundle of flat tubes interposed between two manifolds. This exchanger is a condenser for an air conditioning circuit of a motor vehicle.
Le faisceau 2 est formé d'une multiplicité de tubes plats 4 disposés parallèlement les uns aux autres et alternant avec des intercalaires ondulés 6. Ces intercalaires sont formés à partir d'un feuillard métallique qui est déformé pour constituer des ondulations. Un intercalaire 6 est disposé entre deux tubes adjacents 4 et vient au contact respectif de ces deux tubes 4 par des régions d'extrémité des ondulations.The beam 2 is formed of a multiplicity of flat tubes 4 arranged parallel to each other and alternating with corrugated inserts 6. These spacers are formed from a metal strip which is deformed to form corrugations. An interlayer 6 is disposed between two adjacent tubes 4 and comes into respective contact with these two tubes 4 by end regions of the corrugations.
Les tubes 4 du faisceau sont insérés, à chacune de leurs extrémités, dans des ouvertures réalisées dans des plaques collectrices 8, également appelées collecteurs. Les plaques collectrices 8 sont fermées par un couvercle 9 pour consti¬ tuer des boîtes collectrices 10, par exemple des boîtes à liquide de refroidissement ou à air.The tubes 4 of the bundle are inserted, at each of their ends, in openings made in collector plates 8, also called collectors. The collector plates 8 are closed by a cover 9 to consti¬ kill manifolds 10, for example coolant boxes or air.
Pour créer des passes dans l'échangeur, il est nécessaire d'intégrer des cloisons 12 qui divisent les boîtes collectri¬ ces 10 en chambres séparées.To create passes in the exchanger, it is necessary to integrate partitions 12 which divide the boxes collectri¬ these 10 into separate rooms.
Cet échangeur est alimenté au niveau de ses boîtes collectri¬ ces 10 par deux brides 14 qui reçoivent chacune respective- ment une tubulure d'entrée 16 et une tubulure de sortie 18 par lesquelles le fluide entre et sort de l'êchangeur.This exchanger is fed at its boxes collectri¬ these 10 by two flanges 14 which receive each respective- An inlet manifold 16 and an outlet manifold 18 through which the fluid enters and exits the exchanger.
Ce type d'échangeur est très utile pour fabriquer par exemple des condenseurs pour circuit de climatisation de véhicule automobile.This type of exchanger is very useful for manufacturing, for example, condensers for a motor vehicle air conditioning circuit.
Les figures 2 et 3 sont des vues en perspective d'une boîte collectrice utilisée dans l'êchangeur de la figure 1. Cette boîte collectrice 10 est en deux parties, constituée de la plaque collectrice 8 dans laquelle s'emboîte le couvercle 9.Figures 2 and 3 are perspective views of a manifold used in the exchanger of Figure 1. This manifold 10 is in two parts, consisting of the manifold plate 8 in which fits the cover 9.
La plaque collectrice 8 est en aluminium et a une forme en demi-cylindre évidé. La plaque collectrice 8 a une épaisseur déterminée, et reçoit, dans l'échangeur monté, le faisceau 2 de tubes plats dans une partie inférieure du demi-cylindre indiqué par la flèche F. Pour des raisons pratiques, les ouvertures de réception des tubes de la plaque collectrice 8 ne sont pas représentées.The collector plate 8 is made of aluminum and has a hollow half-cylinder shape. The collecting plate 8 has a determined thickness, and receives, in the mounted exchanger, the bundle 2 of flat tubes in a lower part of the half-cylinder indicated by the arrow F. For practical reasons, the openings for receiving the tubes of the collector plate 8 are not shown.
Le couvercle 9 est également en aluminium. Il a une forme en demi-cylindre identique à celle de la plaque collectrice 8, prolongée par deux bords de liaison 22. Les bords 22 présen¬ tent un pincement. Ce pincement permet la liaison de la plaque collectrice 8 et du couvercle 9. En effet, le cou¬ vercle peut venir recouvrir la plaque collectrice 8, grâce à leurs demi-cylindres respectifs. Simultanément, les bords 22 viennent en appui sur une paroi interne 23 de la plaque collectrice 8, grâce au pincement des bords 22.The lid 9 is also made of aluminum. It has a half-cylinder shape identical to that of the header plate 8, extended by two connecting edges 22. The edges 22 présen¬ tent a pinch. This nip allows the connection of the collector plate 8 and the cover 9. In fact, the cou¬ vercle can come to cover the collector plate 8, thanks to their respective half-cylinders. At the same time, the edges 22 bear against an internal wall 23 of the collecting plate 8, thanks to the pinching of the edges 22.
L'un des bords 22 présente un évidement 24, ici situé à l'extrémité du couvercle 9. Cet évidement est pratiqué sur la totalité de la hauteur du bord de liaison 22, de sorte qu'il est recouvert par la plaque collectrice 8 lorsque le cou- vercle 9 s'emboîte sur celle-ci (comme on peut le voir sur la figure 3), et que l'extrémité du couvercle 9 accessible à travers 1 'évidement 24 appartient à la partie en forme de demi-cylindre.One of the edges 22 has a recess 24, here located at the end of the cover 9. This recess is made over the entire height of the connecting edge 22, so that it is covered by the header plate 8 when the cover 9 fits over it (as can be seen in FIG. 3), and that the end of the cover 9 accessible to through the recess 24 belongs to the half-cylinder shaped part.
L'évidement 24 se prolonge par un évidement partiel 26 de la partie en forme de demi-cylindre du couvercle 9. Le rôle de cet évidement sera explicité plus loin.The recess 24 is extended by a partial recess 26 of the half-cylinder-shaped portion of the cover 9. The role of this recess will be explained later.
La figure 4 est une vue en coupe d'une bride 14 de 1 'êchangeur de la figure 1. Selon ce mode de réalisation, on propose que les brides 14 soient des brides d'entrée et/ou de sortie de fluide.FIG. 4 is a sectional view of a flange 14 of the exchanger of FIG. 1. According to this embodiment, it is proposed that the flanges 14 are inlet flanges and / or fluid outlet flanges.
La bride 14 comporte un corps 140 creusé d'un trou borgne 142 côte à côte avec une ouverture traversante 144.The flange 14 comprises a body 140 dug a blind hole 142 side by side with a through opening 144.
Le trou borgne 142 est destiné à recevoir des moyens de fixation de l'êchangeur de chaleur dans son environnement.The blind hole 142 is intended to receive means for fixing the heat exchanger in its environment.
L'ouverture 144 présente un axe W. Une partie supérieure de la bride est destinée à recevoir la tubulure d'entrée 16 ou de sortie 18 de fluide, l'ouverture 144 se rétrécissant ensuite dans une partie inférieure qui débouche du corps 140 dans la boîte collectrice 10 en 146.The opening 144 has an axis W. An upper portion of the flange is intended to receive the inlet tubing 16 or fluid outlet 18, the opening 144 then tapering into a lower part which opens out of the body 140 into the collector box 10 in 146.
Dans la partie inférieure de l'ouverture 144, près du débouchement 146, la bride 14 comporte un moyen de forme complémentaire à la paroi interne de l'évidement 24. Ce moyen pourra notamment prendre la forme d'une saillie 148 que l'on peut observer plus précisément sur les figures 5 et 6 et dont le rôle sera explicité plus loin.In the lower part of the opening 144, near the outlet 146, the flange 14 has a means of complementary shape to the inner wall of the recess 24. This means may in particular take the form of a projection 148 which is can observe more precisely in Figures 5 and 6 and whose role will be explained later.
Sur la figure 5 qui est vue en coupe selon l'axe W de la bride 14, on peut voir que le corps 140 de la bride 14 présente deux gradins 150 et 152 de telle sorte que l'épaisseur du corps 140 qui entoure l'ouverture 144 est sensiblement constante. L'extrémité inférieure 153 de la bride 14 a un profil sensiblement en quart de cercle dont dépasse la saillie 148, de telle sorte que cette extrémitéIn Figure 5 which is seen in section along the axis W of the flange 14, it can be seen that the body 140 of the flange 14 has two steps 150 and 152 so that the thickness of the body 140 surrounding the aperture 144 is substantially constant. The lower end 153 of the flange 14 has a substantially quarter-circle profile of which protrudes 148, so that this end
153 épouse la forme du couvercle 9 et de la partie collec¬ trice 8 au niveau des bords 22 du couvercle 9. La saillie 148 présente un enfoncement 154 dont la forme est similaire à celle du pincement des bords 22 du couvercle 9.153 matches the shape of the cover 9 and the collec¬ trice 8 at the edges 22 of the cover 9. The projection 148 has a recess 154 whose shape is similar to that of the nipping of the edges 22 of the cover 9.
Ce détail est notamment appréciable sur la figure 6 gui est un agrandissement de la référence VI de la figure 5. Comme on le voit sur la figure 6, la saillie 148 est munie à son extrémité 153 d'excroissances coopérant avec la paroi interne 23 du collecteur. Les excroissances dégagent deux espaces 156 et 158 entre la saillie 148 et le corps 140 de la bride dont l'épaisseur est sensiblement égale à celle du couvercle 9 et de la partie collectrice 8. La saillie 148 correspond exactement en forme et en taille à l'évidement 24 du couvercle 9. La saillie 148 permet ainsi le blocage en position de la bride 14 avant le brasage.This detail is particularly appreciable in Figure 6 which is an enlargement of the reference VI of Figure 5. As seen in Figure 6, the projection 148 is provided at its end 153 of excrescences cooperating with the inner wall 23 of the manifold. The protrusions emit two spaces 156 and 158 between the projection 148 and the body 140 of the flange whose thickness is substantially equal to that of the cover 9 and the collector portion 8. The projection 148 corresponds exactly in shape and size to the 24 of the cover 9. The projection 148 thus allows the locking in position of the flange 14 before brazing.
De même, la bride 14 est ainsi faite que l'ouverture 144 débouchant en 146 est prévue pour assurer le passage du fluide de 1 ' extérieur vers 1 ' intérieur de 1 'êchangeur et inversement .Similarly, the flange 14 is thus made that the opening 144 opening 146 is provided to ensure the passage of fluid from one outside to 1 inside the exchanger and vice versa.
La figure 7 montre comment la bride 14 est montée sur la boîte collectrice 10. Avant de venir emboîter le couvercle 9 sur la plaque collectrice 8, on vient poser la bride 14 au niveau de l'évidement 24 du couvercle 9, en appui sur celui- ci. La saillie 148 ayant exactement la même taille que l'évidement 24, elle "bouche" celui-ci et on vient bloquer la bride 14 en emboîtant la plaque collectrice 8 dans le trou 158 d'une part et contre le demi-cylindre du couvercle 9 d'autre part, l'espace 156 étant rempli par celui-ci en regard de l'ouverture 24.FIG. 7 shows how the flange 14 is mounted on the manifold 10. Before fitting the cover 9 onto the collector plate 8, the flange 14 is placed at the recess 24 of the cover 9, resting on the flange 14. - this. The projection 148 having exactly the same size as the recess 24, it "plugs" it and we just block the flange 14 by fitting the collector plate 8 in the hole 158 on the one hand and against the half-cylinder of the cover 9 on the other hand, the space 156 being filled by the latter opposite the opening 24.
Comme on peut le voir sur la figure 5, la saillie présente ici une encoche afin de dégager l'ouverture 146 de la bride 14, en regard de l'évidement partiel 26. L'évidement partiel 26 permet d'améliorer le flux du fluide débouchant enAs can be seen in FIG. 5, the projection here has a notch in order to disengage the opening 146 from the flange 14, opposite the partial recess 26. The recess 26 allows to improve the flow of the fluid opening into
146 vers la boîte collectrice 10 et inversement.146 to the manifold 10 and vice versa.
Ceci est dû au fait que la bride forme ici un angle de 90° avec le plan du faisceau 2. Dans cette forme de réalisation, la saillie 148 de la bride 14 et l'ouverture 144 qui permet la connexion à la boîte collectrice 10 sont liées.This is because the flange here forms a 90 ° angle with the plane of the beam 2. In this embodiment, the projection 148 of the flange 14 and the opening 144 which allows connection to the manifold 10 are linked.
En effet, comme on le voit sur la figure 8, si la bride fait un angle non nul et non droit avec le plan du faisceau 2, la saillie 148 de la bride 14 et 1 'évidément 24 du couvercle 9 restent inchangés, mais l'on prévoit un autre évidement 200 à l'angle a choisi dans le demi-cylindre du couvercle 9 et l'on place l'ouverture 144 de la bride en face. L'évidement partiel 26 est également déplacé pour faire face à l'ouverture 144. La saillie 148 et l'ouverture 144 sont alors indépendantes. La position de la saillie par rapport à l'axe longitudinal W dépend de la valeur de l'angle α.Indeed, as seen in Figure 8, if the flange is a non-zero angle and not straight with the plane of the beam 2, the projection 148 of the flange 14 and 1 'recess 24 of the cover 9 remain unchanged, but the provision is made for another recess 200 at the angle α chosen in the half-cylinder of the cover 9 and the opening 144 of the opposite flange is placed. The partial recess 26 is also moved to face the opening 144. The projection 148 and the opening 144 are then independent. The position of the projection relative to the longitudinal axis W depends on the value of the angle α.
Les figures 9 à 11 représentent un réservoir 220 destiné à équiper un échangeur tel que décrit plus haut . Le réservoir comporte des moyens de liaison 14 du réservoir 220 sur l'échangeur, les moyens de liaison 14 étant des brides 14 tel que décrit précédemment. Le réservoir loge habituellement des moyens de filtration pour diviser l'intérieur du réservoir en un compartiment amont qui reçoit le fluide réfrigérant condensé, non filtré, et un compartiment aval qui reçoit le fluide réfrigérant condensé et filtré. Habituellement, le réservoir loge aussi des moyens de déshydratation, par exemple une cartouche déshydratante, logée dans le compartiment amont du réservoir.Figures 9 to 11 show a reservoir 220 for equipping an exchanger as described above. The reservoir comprises connecting means 14 of the reservoir 220 on the exchanger, the connecting means 14 being flanges 14 as described above. The tank usually houses filtration means for dividing the interior of the tank into an upstream compartment that receives condensed, unfiltered refrigerant, and a downstream compartment that receives the condensed and filtered coolant. Usually, the tank also houses dehydration means, for example a desiccant cartridge, housed in the upstream compartment of the tank.
Dans l'exemple représenté, le réservoir 220 comporte trois brides 14. Une première bride 14A, située en partie supérieure du réservoir 220, est une bride d'accrochage. Les deux autres brides 14B et 14C sont situées en partie inférieure du réservoir 220 et sont respectivement une bride de passage de fluide du collecteur de l'échangeur au réservoir et, une bride de passage du fluide du réservoir au collecteur de l'échangeur.In the example shown, the tank 220 has three flanges 14. A first flange 14A, located in the upper part of the tank 220, is a fastening flange. The other two flanges 14B and 14C are located in part lower tank 220 and are respectively a fluid passage flange of the collector of the exchanger to the tank and a flange for passing the fluid from the reservoir to the collector of the exchanger.
La ou les brides sont, par exemple, issues de matière avec le corps du réservoir. Un tel réservoir est obtenu, notamment, par extrusion du corps. Il est prévu muni d'une surépaisseur de matière, dans laquelle sont ensuite formées les brides, par usinage.The flange or flanges are, for example, made from material with the body of the tank. Such a reservoir is obtained, in particular, by extrusion of the body. It is provided with a material thickness, in which are then formed the flanges by machining.
On peut imaginer diverses variantes combinant des caractéris¬ tiques de la description donnée ci-dessus, dans lesquelles notamment l'ouverture 24 n'est pas située en extrémité du couvercle mais n'importe où sur celui-ci, dans lesquelles la bride 14 comporte deux ouvertures du type 144 pour assurer l'entrée et la sortie de fluide, et dans lesquelles ces ouvertures sont placées de sorte que la bride forme un angle quelconque avec le plan du faisceau de l'échangeur de chaleur.One can imagine various variants combining characteristics of the description given above, in which in particular the opening 24 is not located at the end of the cover but anywhere on it, in which the flange 14 comprises two 144-type openings for fluid entry and exit, and wherein these openings are placed so that the flange forms any angle with the plane of the heat exchanger bundle.
On notera que l'échangeur de chaleur 10 est, suite au positionnement de la bride entre les deux parties du collec¬ teur et à l'assemblage des autres pièces de l'échangeur, brasé pour assurer son assemblage.It will be noted that the heat exchanger 10 is, following the positioning of the flange between the two parts of the collec¬ tor and the assembly of the other parts of the exchanger, brazed to ensure its assembly.
L'invention ne se limite pas au mode de réalisation décrit ci-dessus, mais englobe toutes les variantes que l'homme du métier saura envisager à la lumière des revendications qui suivent. The invention is not limited to the embodiment described above, but encompasses all the variants that the skilled person will consider in the light of the claims that follow.
