Description

L'invention concerne un échangeur de chaleur pour le transfert de chaleur entre un premier fluide et un second fluide, comprenant:

  • un boítier central de forme générale cylindrique de révolution constitué par une paroi périphérique cylindrique munie de tubulures d'entrée et de sortie pour le premier fluide et par deux parois d'extrémités;
  • un faisceau de tubes allongés parallèlement à l'axe du boítier, les régions d'extrémités de chaque tube traversant de manière étanche aux fluides des ouvertures ménagées dans lesdites parois d'extrémités, et les faces externes des tubes délimitant à l'intérieur du boítier une chambre pour la circulation du premier fluide; et
  • deux coupelles annulaires de révolution coiffant respectivement les deux extrémités du boítier et liées de manière étanche à la périphérie de celles-ci, pour définir avec les parois d'extrémités des boítes collectrices qui communiquent entre elles par l'intermédiaire des tubes pour la circulation du second fluide, les ouvertures centrales des coupelles constituant respectivement une ouverture d'entrée et une ouverture de sortie pour le second fluide.
The invention relates to a heat exchanger for the transfer of heat between a first fluid and a second fluid, comprising:
  • a central box of generally cylindrical shape of revolution constituted by a cylindrical peripheral wall provided with inlet and outlet pipes for the first fluid and by two end walls;
  • a bundle of elongated tubes parallel to the axis of the housing, the end regions of each tube passing through fluid-tight openings made in said end walls, and the external faces of the tubes delimiting inside the housing a chamber for the circulation of the first fluid; and
  • two annular cups of revolution respectively covering the two ends of the case and sealingly linked to the periphery thereof, to define with the end walls of the manifolds which communicate with each other via the tubes for the circulation of the second fluid, the central openings of the cups respectively constituting an inlet opening and an outlet opening for the second fluid.

De tels échangeurs sont utilisés notamment pour la récupération de chaleur à partir des gaz d'échappement des véhicules automobiles, le premier fluide étant un fluide en circulation pour la récupération de la chaleur, et le second fluide étant constitué par les gaz d'échappement.Such exchangers are used in particular for recovery heat from vehicle exhaust automobiles, the first fluid being a circulating fluid for heat recovery, and the second fluid being consisting of exhaust gases.

Dans ces échangeurs connus, les différents éléments sont mutuellement assemblés de manière étanche aux fluides par brasage, et les coupelles d'extrémité sont des pièces massives moulées. Le matériau utilisé est l'acier inoxydable, pour permettre le brasage. Ces pièces sont reprises en usinage pour assurer l'ajustement de l'assemblage avec les autres composants et pour obtenir le bon état de surface nécessaire au brasage. Le matériau et la technique de fabrication rendent les pièces lourdes et coûteuses.In these known exchangers, the different elements are mutually assembled in a fluid-tight manner by soldering, and the end cups are pieces massive molded. The material used is stainless steel, to allow soldering. These pieces are included in machining to ensure the fit of the assembly with the other components and to obtain the good surface condition necessary for soldering. The material and technique of manufacturing makes parts heavy and expensive.

De plus, les coupelles n'ont aucune élasticité et doivent être emboítées sur le boítier avec jeu. Elles ne peuvent se maintenir sur celui-ci par frottement, et des points de soudure doivent être réalisés pour maintenir les pièces ensemble jusqu'au brasage.In addition, the cups have no elasticity and must be fitted on the case with play. They cannot be keep on it by friction, and points of solder must be made to hold the pieces together until soldering.

Enfin, l'absence d'élasticité des coupelles limite strictement l'ovalisation autorisée du boítier.Finally, the lack of elasticity of the cups strictly limits the authorized ovalization of the case.

FR 2648549 décrit un échangeur de 2 chaleur conforme au préambule de la revendication 1.FR 2648549 describes a heat exchanger 2 conforming to the preamble of claim 1.

Les coupelles en tôle emboutie sont plus légères et moins coûteuses que les coupelles moulées et usinées de l'état de la technique. Leur élasticité facilite leur assemblage avec le boítier, et leur maintien à l'état assemblé avant le brasage.The stamped sheet metal cups are lighter and less expensive than the molded and machined cups of the state of the technique. Their elasticity facilitates their assembly with the housing, and their maintenance in the assembled state before the brazing.

Ces effets sont encore renforcés par une légère ovalisation obtenue naturellement par l'emboutissage à partir d'une tôle laminée de faible épaisseur, qui permet d'obtenir simultanément un jeu diamétral approprié entre le boítier et la coupelle, et un léger serrage dans une direction radiale particulière, permettant le maintien de l'assemblage. L'invention vise notamment un échangeur de chaleur selon la revendication 1. These effects are further reinforced by a slight ovalization obtained naturally by stamping from a thin rolled sheet, which allows to simultaneously obtain an appropriate diametral clearance between the housing and the cup, and a slight tightening in one direction particular radial, allowing the maintenance of the assembly. The invention relates in particular to a heat exchanger according to claim 1.

Des caractéristiques optionnelles de l'invention, complémentaires ou alternatives, sont énoncées ci-après:

  • L'une au moins des coupelles présente, à son extrémité axiale tournée à l'opposé du boítier, une portion cylindrique radialement intérieure définissant une tubulure axiale d'entrée ou de sortie pour le second fluide.
  • La face extérieure de la tubulure axiale est brasée à l'intérieur d'un trou traversant formé dans une bride de fixation en forme de plaque qui s'étend perpendiculairement à l'axe du boítier.
  • La coupelle présente, au voisinage de la tubulure axiale, une portion orientée sensiblement radialement qui est brasée sur la face de la bride tournée vers le boítier.
  • L'une au moins des coupelles présente une portion cylindrique d'emboítement recouvrant une région d'extrémité de ladite paroi périphérique.
  • Ladite portion cylindrique d'emboítement est adjacente à une portion évasée située à l'extrémité axiale de la coupelle tournée vers le boítier, propre à faciliter l'emboítement de la coupelle sur le boítier.
  • Ladite portion cylindrique d'emboítement se raccorde à l'opposé du boítier, à une portion de diamètre progressivement décroissant formant butée pour l'extrémité du boítier et définissant un trajet de section variable pour le second fluide entre le boítier et l'ouverture d'entrée ou de sortie.
Optional, complementary or alternative features of the invention are set out below:
  • At least one of the cups has, at its axial end facing away from the housing, a radially inner cylindrical portion defining an axial inlet or outlet manifold for the second fluid.
  • The outer face of the axial tube is brazed inside a through hole formed in a plate-shaped fixing flange which extends perpendicular to the axis of the housing.
  • The cup has, in the vicinity of the axial tube, a substantially radially oriented portion which is brazed on the face of the flange facing the housing.
  • At least one of the cups has a cylindrical socket portion covering an end region of said peripheral wall.
  • Said cylindrical nesting portion is adjacent to a flared portion located at the axial end of the cup facing the housing, suitable for facilitating the nesting of the cup on the housing.
  • Said cylindrical socket portion is connected opposite to the housing, to a portion of progressively decreasing diameter forming a stop for the end of the housing and defining a path of variable section for the second fluid between the housing and the opening of entry or exit.

L'invention a également pour objet un procédé de montage d'un échangeur de chaleur tel que défini ci-dessus, dans lequel, après avoir assemblé le boítier et les tubes, on emboíte les coupelles sur les régions d'extrémités du boítier, et on brase l'ensemble ainsi obtenu, le diamètre extérieur du boítier, le diamètre intérieur de ladite portion cylindrique d'emboítement et l'élasticité des coupelles étant tels que les coupelles s'emboítent avec un frottement permettant leur maintien en place avant le brasage.The invention also relates to a method of mounting a heat exchanger as defined above, in which, after assembling the housing and the tubes, we fit the cups on the end regions of the housing, and braze the assembly thus obtained, the outside diameter of the housing, the inside diameter of said cylindrical portion interlocking and elasticity of the cups being such that the cups fit together with a friction allowing their held in place before brazing.

Le procédé selon l'invention peut comporter au moins certaines des particularités suivantes:

  • Le boítier et/ou les coupelles présentent une légère ovalisation, une première des deux grandeurs constituées par ledit diamètre extérieur et ledit diamètre intérieur ayant une valeur minimale inférieure à la valeur minimale de la seconde desdites grandeurs et une valeur maximale supérieure à la valeur maximale de la seconde grandeur, et le périmètre intérieure de ladite portion d'emboítement étant supérieur au périmètre extérieur du boítier.
  • On poursuit le mouvement d'emboítement des coupelles jusqu'à ce que leur portion de diamètre progressivement décroissant vienne en butée sur l'extrémité du boítier.
The method according to the invention can include at least some of the following features:
  • The housing and / or the cups have a slight ovalization, a first of the two sizes constituted by said outside diameter and said inside diameter having a minimum value less than the minimum value of the second of said sizes and a maximum value greater than the maximum value of the second size, and the inner perimeter of said fitting portion being greater than the outer perimeter of the housing.
  • We continue the interlocking movement of the cups until their progressively decreasing diameter portion abuts on the end of the housing.

Les caractéristiques et avantages de l'invention seront exposés plus en détail dans la description ci-après, en se référant aux dessins annexés.The characteristics and advantages of the invention will be described in more detail in the description below, in referring to the attached drawings.

La figure 5 est un détail agrandi de la figure 4.Figure 5 is an enlarged detail of Figure 4.

Les figures 6 et 7 sont des schémas explicatifs relatifs à l'emboítement d'une coupelle sur le boítier de l'échangeur de chaleur.Figures 6 and 7 are explanatory diagrams relating to the fitting of a cup on the casing of the heat exchanger heat.

L'échangeur de chaleur représenté sur la figure 1 comprend, de manière connue en soi, un boítier central de forme cylindrique de révolution composé d'une paroi périphérique cylindrique 1 et de deux parois d'extrémité circulaires 2, 3. Des tubulures d'entrée et de sortie 4, 5 pour le fluide de refroidissement du moteur du véhicule sont aménagées sur la paroi 1, en des positions diamétralement opposées, l'une au voisinage de la paroi 2 et l'autre au voisinage de la paroi 3. Des trous circulaires répartis sur la surface des parois 2 et 3 reçoivent les extrémités de tubes 6 allongés parallèlement à l'axe A du boítier. Deux coupelles annulaires 7, 8, de révolution autour de l'axe A, coiffent respectivement les extrémités du boítier et se terminent, à l'opposé de celui-ci, par des tubulures axiales 9, 10 qui sont brasées respectivement à des brides 11, 12 destinées à la fixation de l'échangeur de chaleur sur le véhicule. Les parois 1-3, les tubes 6, les coupelles 7, 8 et les brides 11, 12 sont mutuellement assemblés par brasage de manière étanche aux fluides. Les gaz d'échappement pénètrent par la tubulure 9 dans la boíte collectrice 13 délimitée par la paroi 2 et la coupelle 7, cheminent à l'intérieur des tubes 6 pour atteindre la boíte collectrice 14 délimitée par la paroi 3 et la coupelle 8, et sortent par la tubulure 10. Le fluide de refroidissement pénètre par la tubulure 4 à l'intérieur du boítier 1-3, où il chemine en balayant la surface extérieure des tubes de manière à recueillir la chaleur des gaz qui circulent à l'intérieur ceux-ci, puis sort par la tubulure 5. La circulation de chaque fluide peut également s'effectuer en sens inverse de celui qui vient d'être décrit.The heat exchanger shown in FIG. 1 comprises, in a manner known per se, a central box of form cylindrical of revolution composed of a peripheral wall cylindrical 1 and two circular end walls 2, 3. Inlet and outlet pipes 4, 5 for the vehicle engine cooling are fitted on the wall 1, in diametrically opposite positions, one at near wall 2 and the other near wall 3. Circular holes distributed over the surface of the walls 2 and 3 receive the ends of tubes 6 elongated in parallel to axis A of the housing. Two annular cups 7, 8, of revolution around axis A, respectively cover the ends of the case and terminate, opposite it, by axial tubes 9, 10 which are brazed respectively to flanges 11, 12 intended for fixing the heat exchanger on the vehicle. The walls 1-3, the tubes 6, the cups 7, 8 and the flanges 11, 12 are mutually assembled by brazing in a sealed manner fluids. Exhaust gases enter through tubing 9 in the manifold 13 delimited by the wall 2 and the cup 7, run inside the tubes 6 to reach the manifold 14 delimited by the wall 3 and the cup 8, and exit through the tubing 10. The fluid of cooling enters through the tubing 4 inside the box 1-3, where it travels by sweeping the outer surface tubes so as to collect the heat from the gases which circulate inside these, then exit through the tubing 5. The circulation of each fluid can also be carried out opposite direction to that just described.

Selon l'invention, les coupelles 7, 8 sont réalisées par emboutissage à partir d'une tôle laminée de faible épaisseur. Outre la réduction de poids et de coût, cette technique de fabrication permet un maintien en place provisoire des coupelles sur les extrémités du boítier par élasticité jusqu'au brasage comme décrit en détail plus loin.According to the invention, the cups 7, 8 are produced by stamping from a thin rolled sheet. In addition to reducing weight and cost, this technique of manufacturing allows provisional retention of cups on the ends of the case by elasticity until soldering as described in detail below.

On voit sur la figure 2 que la coupelle 8, identique à la coupelle 7, comprend une portion cylindrique 15 qui vient entourer étroitement la région d'extrémité de la paroi cylindrique 1 du boítier. La portion 15 est adjacente à une portion évasée 16, à section en arc de cercle, qui s'étend jusqu'à l'extrémité axiale 17 de la coupelle tournée vers le boítier. A l'opposé de la portion 16, la portion 15 se raccorde à une portion tronconique 18 dont le diamètre va en décroissant lorsqu'on s'éloigne du boítier. La portion 18 se raccorde à son tour, par un arrondi, à une portion 19 s'étendant sensiblement selon un plan radial. Enfin, la portion 19 est reliée par un arrondi 20 à la tubulure 10, qui constitue la partie de plus faible diamètre de la coupelle et qui s'étend jusqu'à l'extrémité axiale de la coupelle opposée au boítier, où elle définit une ouverture 21 d'entrée ou de sortie de gaz.We see in Figure 2 that the cup 8, identical to the cup 7, includes a cylindrical portion 15 which comes tightly surround the end region of the wall cylindrical 1 of the housing. The portion 15 is adjacent to a flared portion 16, of circular arc section, which extends up to the axial end 17 of the cup facing the housing. Unlike portion 16, portion 15 is connects to a frustoconical portion 18 whose diameter goes decreasing when you move away from the case. Portion 18 is in turn connects to a portion 19 extending substantially in a radial plane. Finally, the portion 19 is connected by a round 20 to the pipe 10, which constitutes the part of smaller diameter of the cup and which extends to the axial end of the opposite cup to the housing, where it defines an opening 21 for entry or gas outlet.

La portion évasée 16 facilite l'insertion de l'extrémité du boítier dans la coupelle, laquelle insertion se poursuit jusqu'à ce que la face externe 3a de la paroi d'extrémité 3 du boítier vienne en butée sur la portion tronconique 18 de la coupelle, comme montré en détail sur la figure 3. La portion 18 sert également au guidage du gaz entre la tubulure d'entrée ou de sortie 10 et les extrémités des tubes 6, qui s'inscrivent dans une surface sensiblement supérieure à la section de passage de cette tubulure.The flared portion 16 facilitates the insertion of the end of the housing in the cup, which insertion continues until the outer face 3a of the end wall 3 of the housing comes into abutment on the frustoconical portion 18 of the cup, as shown in detail in Figure 3. The portion 18 also serves to guide the gas between the tubing inlet or outlet 10 and the ends of the tubes 6, which fall within an area significantly larger than the passage section of this tubing.

Les figures 4 et 5 montrent la liaison entre la coupelle 8 et une bride de fixation 22 différente des brides 11 et 12 représentées sur la figure 1. La bride 22 a la forme d'une plaque s'étendant parallèlement à un plan radial, traversée par une ouverture cylindrique centrale 23 dans laquelle se loge la tubulure 10 et par deux trous filetés 24, symétriques l'un de l'autre par rapport à l'axe A, servant à la fixation de l'échangeur de chaleur sur un support non représenté. Comme on le voit plus particulièrement sur la figure 5, la bride 22 est en contact avec la face externe de la portion radiale 19 de la coupelle par sa face 25 tournée vers le boítier, et avec la face externe de la tubulure 10 par la paroi de l'ouverture 23. Elle est brasée à ces deux surfaces, ce qui assure une excellente tenue mécanique de l'assemblage, notamment vis-à-vis des vibrations du moteur du véhicule. Un chanfrein annulaire 26 est ménagé en regard de l'arrondi 20.Figures 4 and 5 show the connection between the cup 8 and a fixing flange 22 different from the flanges 11 and 12 shown in Figure 1. The flange 22 has the shape of a plate extending parallel to a radial plane, traversed by a central cylindrical opening 23 in which is houses the tubing 10 and by two threaded holes 24, symmetrical from each other with respect to axis A, used for fixing of the heat exchanger on a support not shown. As can be seen more particularly in FIG. 5, the flange 22 is in contact with the external face of the portion radial 19 of the cup by its face 25 facing the housing, and with the external face of the tube 10 by the wall of the opening 23. It is brazed to these two surfaces, which ensures excellent mechanical strength of the assembly, in particular with respect to the vibrations of the vehicle engine. A annular chamfer 26 is formed opposite the rounding 20.

La technique de fabrication des coupelles par emboutissage à partir d'une tôle laminée entraíne par elle-même une légère ovalisation, qui facilite l'assemblage de l'échangeur selon l'invention, comme on va l'expliquer en se référant à la figure 6. Sur celle-ci, le cercle hachuré représente schématiquement le boítier cylindrique de révolution 1, 2, de diamètre d1, et l'ellipse non hachurée représente le périmètre intérieur de la portion d'emboítement 15 d'une coupelle, de diamètre minimal d2m et de diamètre maximal d2M, les différences de diamètre étant représentées avec exagération pour plus de clarté. La valeur de d1 est comprise entre celles de dm2 et de d2M, de telle sorte que, lors de l'emboítement, le diamètre minimal de la coupelle augmente, comme indiqué par lés flèches F1, tandis que son diamètre maximal diminue, comme indiqué par les flèches F2. A la fin de l'emboítement, le boítier s'appuie radialement sur la coupelle, en deux endroits diamétralement opposés, selon les flèches F1, maintenant ainsi la coupelle par frottement, tandis qu'un jeu subsiste entre ses deux composants dans la direction des flèches F2, du fait que le périmètre intérieur de la portion 15 est supérieur au périmètre extérieur du boítier.The technique of manufacturing the cups by stamping from a laminated sheet causes by itself a slight ovalization, which facilitates the assembly of the exchanger according to the invention, as will be explained with reference to the figure 6. On this, the hatched circle schematically represents the cylindrical housing of revolution 1, 2, of diameter d 1 , and the unhatched ellipse represents the inside perimeter of the fitting portion 15 of a cup, of diameter minimum d 2m and maximum diameter d 2M , the differences in diameter being exaggerated for clarity. The value of d 1 is between those of d m2 and d 2M , so that, during nesting, the minimum diameter of the cup increases, as indicated by the arrows F1, while its maximum diameter decreases, as indicated by the arrows F2. At the end of the fitting, the case is supported radially on the cup, in two diametrically opposite places, according to the arrows F1, thus maintaining the cup by friction, while a clearance remains between its two components in the direction of arrows F2, because the internal perimeter of the portion 15 is greater than the external perimeter of the housing.

Bien que le cas d'un boítier pratiquement de révolution et d'une coupelle ovalisée soit le plus fréquent, l'invention fonctionne tout aussi bien lorsque le boítier est ovalisé, que la coupelle soit elle-même ovalisée ou de révolution, à la double condition que le diamètre maximal de chacune des deux surfaces cylindriques coopérantes soit supérieur au diamètre minimal de l'autre, et que le périmètre intérieur de la portion 15 soit supérieur au périmètre extérieur du boítier.Although the case of a practically revolutionary case and of an ovalized cup is the most frequent, the invention works just as well when the case is ovalized, whether the cup is itself ovalized or of revolution, the double condition that the maximum diameter of each of the two cooperating cylindrical surfaces is greater than the other's minimum diameter, and that the inner perimeter of portion 15 is greater than the outer perimeter of the housing.

La figure 7 illustre le cas où les deux éléments sont ovalisés, le boítier l'étant plus que la coupelle. On a alors la relation d1m < d2m < d2M < d1M, les lettres m et M indiquant respectivement un diamètre minimal et un diamètre maximal, et les chiffres 1 et 2 étant affectés respectivement au diamètre extérieur du boítier et au diamètre intérieur de la portion d'emboítement 15 de la coupelle. Les flèches F1 marquant la dilatation de la coupelle sont alors orientées dans la direction des diamètres maximaux, et les flèches F2 indiquant la contraction de la coupelle, dans la direction des diamètres minimaux, contrairement au cas de la figure 6.Figure 7 illustrates the case where the two elements are ovalized, the housing being more than the cup. We then have the relation d 1m <d 2m <d 2M <d 1M , the letters m and M respectively indicating a minimum diameter and a maximum diameter, and the numbers 1 and 2 being assigned respectively to the outside diameter of the case and to the inside diameter of the fitting portion 15 of the cup. The arrows F1 marking the expansion of the cup are then oriented in the direction of the maximum diameters, and the arrows F2 indicating the contraction of the cup, in the direction of the minimum diameters, unlike in the case of FIG. 6.
