Abstract

Space between the heat exchanger casing and a series of flat parallel tubes containing high temperature fluid is used to circulate lower temperature fluid. The heat exchanger has a first series of flow channels for a first high temperature fluid, made from thermally conducting material and a second series of flow channels for a second fluid at a lower temperature, also made from a thermally conducting material. These channels intercept perpendicularly so as to ensure heat transfer between the first and second fluids. Each channel is of oblong shape and is divided by insertion of a thermally conducting material fixed to the long internal channel faces on a number of internal channels. The first series of channels are formed from flat parallel tubes (7) juxtaposed in the direction perpendicular to the large axis of their transversal section at pre-set distances between two exterior lateral plates (8). These plates are parallel to the tubes in a casing (9) which is open other lateral faces and is maintained at the top and bottom by input and output collector plates (13, 14) of collector inputs (2) and outputs (3), in which the tubes (7) terminate. The channels of the second series are formed in the spaces between the exterior of the tubes (7) and the plates of the casing (9).

Description

L'invention concerne un échangeur de chaleur du type comprenant une première série de voies d'écoulement d'un premier fluide de température élevée, réalisées en un matériau thermiquement conducteur, et une seconde série de voies d'écoulement d'un second fluide de température plus faible, réalisées en un matériau thermiquement conducteur, qui s'interceptent perpendiculairement pour assurer un échange de chaleur entre les premier et second fluides, chaque voie étant de forme oblongue et divisée, par des moyens intercalaires en un matériau thermiquement conducteur fixés aux faces internes longues des voies, en une pluralité de canaux internes.The invention relates to a heat exchanger of the type comprising a first series of flow paths of a first temperature fluid high, made of a thermally conductive material, and a second series of flow paths of a second lower temperature fluid, made of a thermally conductive material, which are intercepted perpendicularly to ensure a heat exchange between the first and second fluids, each channel being oblong and divided, by intermediate means of a thermally conductive material fixed to the faces long internal channels, in a plurality of internal channels.

Des échangeurs de chaleur de ce type, qui sont connus, sont réalisés sous forme d'un bloc compact dans lequel les différentes voies d'écoulement de fluide sont formées par des lames constituant les parois longues et de barrettes de liaison de ces lames. L'assemblage des lames et des barrettes est réalisé par brasage. Dû à l'effet d'échange thermique entre les deux fluides, dans les voies d'écoulement du fluide à température élevée, il se créé un gradient de température importante entre l'entrée et la sortie du fluide dans l'échangeur.Heat exchangers of this type, which are known, are produced under form of a compact block in which the different flow paths of fluid are formed by blades constituting the long walls and connecting bars of these blades. The assembly of the blades and bars is made by brazing. Due to the heat exchange effect between the two fluids, in the flow paths of the fluid at high temperature, a large temperature gradient between the inlet and outlet of the fluid in the exchanger.

Ce gradient occasionne des contraintes mécaniques dans le bloc compact de l'échangeur, notamment au niveau des fixations des lames et des barrettes, entraínant des fissures et des ruptures.This gradient causes mechanical stresses in the compact block of the exchanger, in particular at the level of the blade and bar attachments, resulting in cracks and breaks.

La présente invention a pour but de proposer un échangeur de chaleur qui pallie les inconvénients qui viennent d'être énoncés, des échangeurs connus.The object of the present invention is to propose a heat exchanger which overcomes the drawbacks which have just been stated, of known exchangers.

Pour atteindre ce but, l'échangeur de chaleur selon l'invention est caractérisé en ce que les voies de la première série sont formées par des tubes plats, parallèles, juxtaposés dans la direction perpendiculaire au grand axe de symétrie de leur section transversale, à des distances prédéterminées, entre deux plaques latérales extérieures parallèles aux tubes qui forment les joues d'une carcasse ouverte aux autres faces latérales, et maintenus en haut et en bas par des plaques collectrices d'entrée et de sortie de collecteurs d'entrée et de sortie dans lesquels débouchent ces tubes, et en ce que les voies de la seconde série sont formées par les espaces entre les tubes plats d'une part, et les tubes extérieurs et les plaques de joue, d'autre part.To achieve this goal, the heat exchanger according to the invention is characterized in that the tracks of the first series are formed by flat tubes, parallel, juxtaposed in the direction perpendicular to the major axis of symmetry of their cross section, at predetermined distances, between two outer side plates parallel to the tubes which form the cheeks a carcass open to the other side faces, and maintained at the top and bottom by inlet and outlet header plates of inlet manifolds and outlet into which these tubes open, and in that the channels of the second series are formed by the spaces between the flat tubes on the one hand, and the outer tubes and the cheek plates, on the other hand.

Selon une caractéristique de l'invention, une des plaques collectrices est montée fixe dans la carcasse tandis que l'autre est libre dans celle-ci.According to a characteristic of the invention, one of the collector plates is fixed rise in the carcass while the other is free therein.

Dans encore une autre caractéristique avantageuse de l'invention, la plaque collectrice qui est montée fixe dans la carcasse est la plaque de collecteur d'entrée de l'échangeur de chaleur.In yet another advantageous characteristic of the invention, the plate collector which is fixedly mounted in the carcass is the collector plate of the heat exchanger.

L'invention sera mieux comprise et d'autres buts, caractéristiques détails et avantages de celle-ci apparaítront plus clairement dans la description explicative qui va suivre faite en référence aux dessins schématiques annexés donnés uniquement à titre d'exemple illustrant plusieurs modes de réalisation de l'invention et dans lesquels :

La figure 1 montre, à titre d'exemple, l'utilisation d'un échangeur de chaleur selon l'invention dans un avion, dans lequel il est monté dans l'écoulement des gaz chauds F1, de l'ordre de par exemple 600°C, pour assurer le refroidissement de ceux-ci par le fluide F2 de par exemple 250°C. Comme on le voit sur la figure, le fluide F1 est amené par un conduit 1, passe à travers l'échangeur A en passant par les collecteurs d'entrée et de sortie respectivement 2 et 3 pour parvenir dans le conduit de sortie 4 raccordé au collecteur 3 par un élément de raccordement souple 5.Figure 1 shows, by way of example, the use of a heat exchanger according to the invention in an airplane, in which it is mounted in the flow of hot gases F1, of the order of for example 600 ° C., to ensure the cooling of these by the fluid F2 of for example 250 ° C. As we seen in the figure, the fluid F1 is brought through a conduit 1, passes through exchanger A passing through the inlet and outlet manifolds respectively 2 and 3 to reach the outlet conduit 4 connected to the manifold 3 by a flexible connection element 5.

La figure 2 montre un mode de réalisation de l'échangeur de chaleur indiqué en A sur la figure 1. Cet échangeur comporte une pluralité de tubes plats 7 parallèles et séparés les uns des autres d'une distance prédéterminée dans la direction perpendiculaire au grand axe de la section transversale des tubes, entre deux plaques latérales 8 parallèles aux tubes 7 d'une carcasse indiquée de façon générale en 9 et de section transversale sensiblement rectangulaire et qui est ouverte aux deux autres faces latérales opposées 10. Les tubes sont réalisés en un matériau thermiquement conducteur. Les deux plaques latérales 8 qui constituent les joues de l'échangeur sont reliées à leurs quatre angles par des cornières 11.Figure 2 shows an embodiment of the indicated heat exchanger at A in FIG. 1. This exchanger comprises a plurality of flat tubes 7 parallel and separated from each other by a predetermined distance in the direction perpendicular to the major axis of the cross section of the tubes, between two side plates 8 parallel to the tubes 7 of an indicated carcass generally at 9 and of substantially rectangular cross section and which is open to the two other opposite lateral faces 10. The tubes are made of a thermally conductive material. The two side plates 8 which constitute the cheeks of the exchanger are connected at their four angles by angles 11.

Les tubes sont maintenus en haut et en bas au niveau du cadre formé par les bords supérieur et inférieur des plaques 8 et les cornières 11 par des plaques collectrices supérieure et inférieure respectivement 14 et 13 qui font partie des échangeurs de chaleur respectivement de sortie 3 et d'entrée 2 selon la figure 1. The tubes are held at the top and bottom at the level of the frame formed by the upper and lower edges of the plates 8 and the angles 11 by plates upper and lower manifolds 14 and 13 respectively which are part of heat exchangers of outlet 3 and inlet 2 respectively according to the figure 1.

L'espace interne de chaque tube 7 est divisé par une bande intercalaire 16 pliée en serpentin en une pluralité de canaux 17 parallèles à l'axe du tube. L'intercalaire est réalisé en un matériau thermiquement conducteur et fixé par brasage sur les faces internes du tube le long de ses lignes de crête. De même, dans chaque espace 18 entre deux tubes adjacents est placée une bande 19 en un matériau thermiquement conducteur, pliée en serpentin. Cet intercalaire est fixé, par brasage, aux parois externes des tubes de façon à diviser l'espace entre les tubes en une pluralité de canaux 20 s'étendant perpendiculairement aux axes des tubes entre les faces ouvertes 10 de la carcasse. L'espace entre chaque tube extérieur 7 et la plaque de joue 8 adjacente est également occupé par un élément intercalaire en serpentin 19. Mais, ce dernier est seulement fixé à la face externe du tube et libre au niveau de la plaque 8.The internal space of each tube 7 is divided by an intermediate strip 16 bent into a serpentine in a plurality of channels 17 parallel to the axis of the tube. The interlayer is made of a thermally conductive material and fixed by brazing on the internal faces of the tube along its crest lines. Of even, in each space 18 between two adjacent tubes is placed a strip 19 of a thermally conductive material, folded into a serpentine. This interlayer is fixed, by brazing, to the external walls of the tubes so as to dividing the space between the tubes into a plurality of channels 20 extending perpendicular to the axes of the tubes between the open faces 10 of the carcass. The space between each outer tube 7 and the cheek plate 8 adjacent is also occupied by a serpentine intermediate element 19. However, the latter is only fixed to the external face of the tube and free at the level from plate 8.

Comme il est indiqué sur la figure 2 et ressort de la figure 1, le fluide F1 traverse les canaux 16 des tubes 7 tandis que le fluide 2 s'écoule à travers les canaux 20 de l'intercalaire 19 disposés à l'extérieur des tubes.As shown in Figure 2 and shown in Figure 1, the fluid F1 crosses the channels 16 of the tubes 7 while the fluid 2 flows through the channels 20 of the interlayer 19 arranged outside the tubes.

Selon une caractéristique essentielle de l'invention, l'une des deux plaques collectrices 13, 14 de préférence la plaque 13 du collecteur d'entrée 2 en raison de la température plus élevée du fluide F1 dans celui-ci, est solidaire en 21 de la carcasse 9, c'est-à-dire des bords inférieurs des plaques 8 et des cornières inférieures 11, tandis que l'autre plaque collectrice, c'est-à-dire la plaque 14 du collecteur de sortie 3, reste libre à l'intérieur du cadre formé par l'extrémité supérieure des plaques 8 et des cornières supérieures 11 en laissant subsister un intervalle 22. Pour assurer à la plaque conductrice supérieure 14 cette liberté de déplacement dans ce cadre, on a, dans la version de réalisation représentée sur la figure 4, donné à cette plaque des dimensions inférieures à celles de la plaque conductrice d'entrée 13, tandis que dans la version selon la figure 5, les deux plaques collectrices 13 et 14 et ainsi les deux collecteurs 2 et 3 présentent les mêmes dimensions et seulement les plaques latérales 8 sont au niveau de leur extrémité supérieure déportées vers l'extérieur. According to an essential characteristic of the invention, one of the two plates manifolds 13, 14 preferably the plate 13 of the inlet manifold 2 in due to the higher temperature of the fluid F1 therein, is integral in 21 of the carcass 9, that is to say of the lower edges of the plates 8 and of the lower angles 11, while the other collector plate, that is to say the plate 14 of the outlet manifold 3, remains free inside the frame formed by the upper end of the plates 8 and the upper angles 11 in leaving an interval 22. To ensure the conductive plate superior 14 this freedom of movement within this framework, we have, in the version of embodiment shown in Figure 4, given to this plate of dimensions smaller than those of the input conductive plate 13, while that in the version according to FIG. 5, the two header plates 13 and 14 and thus the two collectors 2 and 3 have the same dimensions and only the side plates 8 are at their upper end deported to the outside.

Il est à noter que l'intervalle 22 ainsi ménagé entre la plaque collectrice 13 et les parois 8 et les cornières 11 peut être obturé par un joint d'étanchéité non représenté pour empêcher une fuite de fluide F2 à travers l'intervalle 22. C'est dû à ce joint que l'intervalle se trouve de préférence du côté de l'échangeur dans lequel la température du fluide est plus faible.It should be noted that the gap 22 thus formed between the collecting plate 13 and the walls 8 and the angles 11 can be closed by a non-sealing gasket shown to prevent leakage of fluid F2 through gap 22. This is due to this seal that the gap is preferably on the side of the exchanger in which the temperature of the fluid is lower.

Etant donné que l'ensemble formé par les tubes 7 avec les intercalaires 16 et 19 et les plaques conductrices 13 et 14 n'est pas fixé à la carcasse à une extrémité, en l'occurrence l'extrémité supérieure de sortie du fluide F1, le gradient de température entre l'entrée et la sortie de l'échangeur ne peut pas produire des contraintes thermiques mécaniques susceptibles de provoquer des fissures et criques comme dans les échangeurs de chaleur connus.Since the assembly formed by the tubes 7 with the spacers 16 and 19 and the conductive plates 13 and 14 is not fixed to the carcass at a end, in this case the upper outlet end of the fluid F1, the temperature gradient between the inlet and the outlet of the exchanger cannot produce mechanical thermal stresses likely to cause cracks and cracks as in known heat exchangers.

Les figures 6 à 10 montrent plusieurs modes de réalisation de l'échangeur de chaleur proposé par l'invention. Sur la figure 6, l'échangeur de chaleur est du type à deux passes à contre-courant. Les collecteurs d'entrée et de sortie avec leurs plaques collectrices indiquées respectivement en 25 et 26 sont juxtaposées à l'extrémité supérieure de l'échangeur. L'espace interne de la carcasse est divisé en deux compartiments 29, 30 par une cloison médiane axiale 27. Chaque compartiment 29, 30 loge une unité d'échangeur de chaleur. Les deux compartiments sont reliés en bas par un collecteur commun 31 dont les plaques collectrices de maintien des tubes 7 sont solidaires de la carcasse tandis que les plaques collectrices d'entrée et de sortie 25 et 26 sont libres. L'intervalle existant entre ces plaques et la carcasse est indiqué en 34.Figures 6 to 10 show several embodiments of the heat exchanger heat proposed by the invention. In Figure 6, the heat exchanger is two-pass type against the current. Input and output collectors with their collector plates indicated respectively in 25 and 26 are juxtaposed at the upper end of the exchanger. The internal space of the carcass is divided into two compartments 29, 30 by a central partition axial 27. Each compartment 29, 30 houses a heat exchanger unit. The two compartments are connected at the bottom by a common collector 31 of which the collector plates for holding the tubes 7 are integral with the carcass while the inlet and outlet header plates 25 and 26 are free. The interval between these plates and the carcass is indicated in 34.

La figure 7 illustre un échangeur de chaleur à trois passes à contre-courant. Cet échangeur comporte trois compartiments 36, 37, 38 traversés successivement par le fluide F1. Les compartiments 36 et 37, d'une part, et les compartiments 37 et 38 d'autre part sont reliés par un collecteur commun respectivement 39, 40. Dans cet échangeur le collecteur d'entrée 41 est désolidarisé de la carcasse, le collecteur commun 39 est solidaire et l'échangeur commun 40 est désolidarisé au niveau des compartiments 37 et 38. Figure 7 illustrates a three-pass counter-current heat exchanger. This exchanger has three compartments 36, 37, 38 crossed successively by the fluid F1. On the one hand, compartments 36 and 37 and the compartments 37 and 38 on the other hand are connected by a common collector respectively 39, 40. In this exchanger the inlet manifold 41 is disconnected from the carcass, the common collector 39 is integral and the common exchanger 40 is separated at the level of the compartments 37 and 38.

Les figures 8 et 9 montrent un échangeur du même type que celui représenté sur les figures 2 à 5, mais pourvu d'un collecteur intermédiaire 42 pour permettre le prélèvement de fluide F1' d'une température supérieure à celle du fluide dans le collecteur supérieur 3, par exemple pour le dégivrage des ailes d'un avion. Dans cet échangeur de chaleur, les plaques collectrices 13 et 14 de l'échangeur d'entrée sont désolidarisées de la carcasse 8, tandis que le collecteur 42 est fixé aux deux plaques extérieures de carcasse 8. Mais il est également possible de laisser le collecteur 42 et la plaque 14 libres, tandis que la plaque 13 est fixée aux plaques 8.Figures 8 and 9 show an exchanger of the same type as that shown in Figures 2 to 5, but provided with an intermediate manifold 42 for allow the fluid F1 ′ to be withdrawn at a temperature higher than that of the fluid in the upper manifold 3, for example for defrosting the wings of an airplane. In this heat exchanger, the collector plates 13 and 14 of the inlet exchanger are separated from the carcass 8, while the collector 42 is fixed to the two outer carcass plates 8. But it is also possible to leave the collector 42 and the plate 14 free, while the plate 13 is fixed to the plates 8.

Enfin la figure 10 montre une version d'échangeur de chaleur dans lequel, par rapport au mode de réalisation sur la figure 1, chaque voie d'écoulement du fluide F1 est formée par deux tubes 7a et 7b juxtaposés dans la direction du grand axe de la section transversale.Finally Figure 10 shows a version of heat exchanger in which, for relative to the embodiment in FIG. 1, each flow path of the fluid F1 is formed by two tubes 7a and 7b juxtaposed in the direction of the major axis of the cross section.

Bien entendu de nombreuses modifications peuvent être apportées aux modes de réalisation de l'échangeur selon l'invention représenté, sans sortir du cadre de l'invention. Ainsi, au lieu d'être oblongs, les tubes pourraient avoir d'autres formes et être courbes dans leur section transversale. Il n'est également pas nécessaire que, dans un même faisceau, tous les tubes aient la même longueur ou soient rectilignes. Concernant l'intercalaire, au lieu d'être formé par une bande en serpentin fixée par brasage sur les faces du tube, l'intercalaire, pourrait venir de matière et les tubes réalisés avec les ailettes, par exemple par extrusion. Enfin, dans le cas de la figure 10, chaque voie d'écoulement pourrait être formée par plus de deux tubes. La conception de l'échangeur est valable par tout matériau métallique ou composite.Of course many modifications can be made to the modes embodiment of the exchanger according to the invention shown, without departing from the scope of the invention. So instead of being oblong, the tubes could have other shapes and be curved in their cross section. It is also not necessary that, in the same bundle, all the tubes have the same length or be straight. Regarding the interlayer, instead of being trained by a serpentine band fixed by brazing on the faces of the tube, the interlayer, could come from material and the tubes produced with the fins, for example by extrusion. Finally, in the case of Figure 10, each channel flow could be formed by more than two tubes. The design of the exchanger is valid for any metallic or composite material.

Les figures 11 et 12 montrent un mode de réalisation de l'échangeur selon l'invention, qui est particulièrement approprié dans le cas où une forte pression règne dans l'espace 18 entre tubes adjacents 7. Dans ce mode de réalisation, les joues 8 de la carcasse 9 sont divisées avantageusement au niveau de leurs lignes médiane en deux parties 45, 46 respectivement solidaires des collecteurs d'entrée 2 et de sortie 3. Les deux parties de joue 45, 46 sont reliées au niveau de leurs bords adjacents 47, 48 par un organe de liaison étanche souple 50, par exemple en forme d'une bande ou d'un soufflet. Comme on le voit clairement sur la figure 12, les bandes intercalaires 19 disposées dans l'espace entre les tubes plats extérieurs 7 et les parties de joue 45, 46 sont fixées au niveau de leur sommet à ces parties.Figures 11 and 12 show an embodiment of the exchanger according to the invention, which is particularly suitable in the case where high pressure reigns in the space 18 between adjacent tubes 7. In this embodiment, the cheeks 8 of the carcass 9 are advantageously divided at their midline in two parts 45, 46 respectively integral with the inlet 2 and outlet 3 collectors. The two cheek parts 45, 46 are connected at their adjacent edges 47, 48 by a connecting member flexible seal 50, for example in the form of a band or a bellows. As clearly seen in Figure 12, the intermediate strips 19 arranged in the space between the outer flat tubes 7 and the cheek portions 45, 46 are fixed at their top to these parts.

L'organe de liaison souple 50 pourrait être renforcé par un élément de renforcement 51 par exemple en métal pour une meilleure tenue en pression.The flexible connecting member 50 could be reinforced by an element of reinforcement 51 for example in metal for better pressure resistance.

Sur les figures l'organe de liaison 50 est monté sur la face extérieure des parties de joue 45 et 46, mais pourrait également être placé sur les faces intérieures.In the figures, the connecting member 50 is mounted on the outside of the cheek pieces 45 and 46, but could also be placed on the sides interior.

Il est à noter que l'écart entre les bords adjacents 48 et 47 des deux parties de joue 45 et 46 est très faible à froid. Les bords pourraient même être jointifs. De ce fait, il ne serait même pas nécessaire de supprimer une onde de l'intercalaire. Il suffirait de la couper le long de sa ligne de crête et de fixer les deux portions de crête séparées respectivement à l'une et l'autre partie de joue.It should be noted that the difference between the adjacent edges 48 and 47 of the two parts of plays 45 and 46 is very weak when cold. The edges could even be joined. Of this fact, it would not even be necessary to delete a wave of the interlayer. It would suffice to cut it along its crest line and fix the two peak portions separated respectively from one and the other part of play.

Bien entendu les joues pourraient être divisées aussi en un plus grand nombre de parties que dans la version représentée. Il importe seulement que cette division en au moins deux parties, avec recouvrement étanche des zones de séparation par des organes de liaison étanche et souple confèrent à la carcasse la liberté de déplacement qui, dans le mode de réalisation selon les figures 1 à 5, est assuré par l'intervalle 22 entre les joues et le collecteur de sortie.Of course the cheeks could also be divided into a larger number than in the version shown. It is only important that this division into at least two parts, with tight overlap of the areas of separation by tight and flexible connecting members give the carcass freedom of movement which in the embodiment according to Figures 1 to 5, is provided by the interval 22 between the cheeks and the manifold exit.
