Description

Faisceau de plaques pour un échangeur thermique et échangeur thermique comportant un tel faisceau de plaques. Plate bundle for a heat exchanger and heat exchanger comprising such a plate bundle.
La présente invention a pour objet un faisceau de plaques pour un échangeur thermique permet¬ tant de réaliser un échange thermique entre deux fluides circulant à contre-courant . La présente invention a également pour objet un échangeur thermique muni d'un tel faisceau de plaques.The present invention relates to a bundle of plates for a heat exchanger allowing so much to carry out a heat exchange between two fluids circulating against the current. The present invention also relates to a heat exchanger provided with such a bundle of plates.
Les échangeurs thermiques sont généralement de deux types .There are generally two types of heat exchangers.
Le premier type d' échangeur thermique comporte un faisceau de tubes en forme de "U" ou un faisceau de tubes droits, dans lequel circule un fluide.The first type of heat exchanger comprises a bundle of "U" shaped tubes or a bundle of straight tubes, in which a fluid circulates.
Mais, ce type d'échangeur est d'une concep¬ tion coûteuse et le rendement thermique est limité compte tenu que le nombre de tubes dépend de la place disponible qui est dans la plupart des cas restreinte.However, this type of exchanger is of an expensive design and the thermal efficiency is limited given that the number of tubes depends on the space available which is in most cases limited.
Le second type d'échangeur thermique comporte un faisceau de plaques disposées jointivement et parallè¬ lement les unes aux autres.The second type of heat exchanger comprises a bundle of plates arranged contiguously and parallel to one another.
Les plaques constituées de tôles fines, le plus souvent en acier inoxydable, comportent des bords à surface lisse et une partie centrale munie d'ondula¬ tions par lesquelles elles sont en contact les unes sur les autres et par lesquelles elles délimitent un double circuit de circulation de deux fluides indépendants et à contre-courant d'une extrémité à l'autre du faisceau de plaques.The plates made of thin sheets, most often made of stainless steel, have edges with a smooth surface and a central part provided with corrugations by which they are in contact with one another and by which they delimit a double circuit of circulation of two independent and counter-current fluids from one end to the other of the plate bundle.
L'assemblage des plaques pour former le faisceau est réalisé de la façon suivante.The assembly of the plates to form the bundle is carried out as follows.
Tout d'abord, les plaques sont empilées en intercalant, entre les bords longitudinaux de chaque plaque, une languette formant entretoise.First of all, the plates are stacked by inserting, between the longitudinal edges of each plate, a tab forming a spacer.
Ensuite, une couche de soudure est déposée sur toute la hauteur de chaque surface latérale du faisceau pour former un mur de soudure étanche, puis les extrémités des entrées et des sorties de chaque canal sont constituées par soudage.Then, a layer of solder is deposited over the entire height of each lateral surface of the beam to form a tight weld wall, then the ends of the inlets and outlets of each channel are formed by welding.
Chaque mur de soudure est réalisé par une succession ascendante de passes horizontales de soudage.Each weld wall is produced by an ascending succession of horizontal welding passes.
Un tel mode de réalisation du faisceau de plaques nécessite une quantité de métal importante et un temps considérable pour l'exécution de l'opération de soudage . De plus, cette technique présente un autre inconvénient .Such an embodiment of the plate bundle requires a large amount of metal and a considerable time for the execution of the welding operation. In addition, this technique has another drawback.
En effet, l'épreuve d'étanchéité, avant l'utilisation du faisceau, n'est réalisable qu'après l'assemblage de toutes les plaques. Par conséquent, en cas de fuite, la recherche de l'origine de la fuite est délicate et fastidieuse, compte tenu que cette recherche n'est possible que par élimination de zones.Indeed, the tightness test, before the use of the beam, is only possible after the assembly of all the plates. Consequently, in the event of a leak, the search for the origin of the leak is delicate and tedious, given that this search is only possible by eliminating zones.
On imagine aisément les difficultés qui en découlent.One can easily imagine the difficulties that arise from this.
L'invention a donc pour but d'éviter les inconvénients précédemment mentionnés en proposant un faisceau de plaques plus simple et moins coûteux à réaliser et dont l'épreuve d'étanchéité est facilitée. L'invention a donc pour objet un faisceau de plaques pour un échangeur thermique, du type comprenant un empilement de plaques d'échange thermique métalliques et parallèles les unes aux autres comportant des bords à surface lisse et une partie centrale munie d'ondula- tions pour former avec les plaques associées un double circuit de circulation de deux fluides indépendants et à contre-courant, caractérisé en ce que chaque plaque d'échange thermique comporte, au niveau de ses bords longitudinaux, un organe de liaison aux deux plaques adjacentes, au niveau de ses bords d'extrémité, un organe de liaison avec une plaque adjacente pour former une superposition alternée d'extrémités ouvertes ou fermées et, au niveau de ses angles, un organe de raccordement des plaques d'échange thermique et des organes de liaison entre eux.The object of the invention is therefore to avoid the drawbacks mentioned above by proposing a bundle of plates which is simpler and less costly to produce and whose sealing test is facilitated. The subject of the invention is therefore a bundle of plates for a heat exchanger, of the type comprising a stack of metal heat exchange plates and parallel to each other having edges with a smooth surface and a central part provided with undulations. to form with the associated plates a double circulation circuit of two independent and counter-current fluids, characterized in that each heat exchange plate comprises, at its longitudinal edges, a member for connecting to the two adjacent plates, at level of its end edges, a connecting member with an adjacent plate to form an alternating superposition of open or closed ends and, at its angles, a connecting member of the heat exchange plates and connecting members together.

The characteristics and advantages of the invention will become apparent during the description which follows, given solely by way of example and made with reference to the accompanying drawings, in which: FIG. 1 is a schematic perspective view of part of a bundle of plates according to the invention,

- la Fig. 6 est une vue en perspective d'une pièce d'un élément de raccordement. Sur la Fig. 1 , on a représenté partiellement un faisceau de plaques d'un échangeur thermique désigné dans son ensemble par la référence 1 et destiné à réaliser un échange thermique entre deux fluides circu¬ lant à contre-courant . Le faisceau de plaques 1 se compose d'un empilement de plaques 2 métalliques de faible épaisseur et parallèles les unes aux autres.- Fig. 6 is a perspective view of a part of a connecting element. In Fig. 1, there is partially shown a bundle of plates of a heat exchanger designated as a whole by the reference 1 and intended to carry out a heat exchange between two fluids circulating against the current. The bundle of plates 1 is composed of a stack of metallic plates 2 of small thickness and parallel to one another.
Chaque plaque 2 est constituée d'une tôle fine, le plus souvent en acier inoxydable ou tout autre matériau suffisamment ductile.Each plate 2 consists of a thin sheet, most often made of stainless steel or any other sufficiently ductile material.
Chaque plaque 2 comporte des bords longitudi¬ naux et transversaux, respectivement 2a et 2b, à surface lisse et une partie centrale 2c munie d'ondulations.Each plate 2 has longitudinal and transverse edges, respectively 2a and 2b, with a smooth surface and a central part 2c provided with corrugations.
Les plaques 2 définissent entre elles des intervalles. Un intervalle sur deux forme un premier circuit a longitudinal pour un premier fluide A et les autres intervalles forment un second circuit b longitudi¬ nal pour un second fluide B, lesdits circuits s'étendant sur toute la longueur du faisceau de plaques 1. Les circuits a et b sont indépendants et à contre-courant .The plates 2 define intervals between them. One interval out of two forms a first longitudinal circuit for a first fluid A and the other intervals form a second longitudinal circuit b for a second fluid B, said circuits extending over the entire length of the bundle of plates 1. The circuits a and b are independent and against the current.
Chaque plaque 2 d'échange thermique comporte:Each heat exchange plate 2 comprises:
- au niveau de ses bords longitudinaux 2a, un organe de liaison 10 aux deux plaques 2 adjacentes, - au niveau de ses bords d'extrémité 2b, un organe de liaison 20 avec une plaque 2 adjacente pour former une superposition alternée d'extrémités ouvertes 3 ou fermées 4,- at its longitudinal edges 2a, a connecting member 10 to the two adjacent plates 2, - at its end edges 2b, a connecting member 20 with an adjacent plate 2 to form an alternating superposition of open ends 3 or closed 4,
- et au niveau de ses angles, un organe de raccordement 30 des plaques 2 d'échange thermique et des organes de liaison 10 et 20 entre eux.- And at its angles, a connecting member 30 of the heat exchange plates 2 and connecting members 10 and 20 between them.
Le faisceau de plaques 1 comporte également au niveau de ses bords d'extrémité 2b, au moins un élément de raccordement 40 à des collecteurs 9 d'entrée et de sortie des fluides. Ces collecteurs 9 sont repré¬ sentés en traits mixtes sur la Fig.l afin de ne pas surcharger le dessin.The bundle of plates 1 also comprises at its end edges 2b, at least one connection element 40 to collectors 9 for inlet and outlet of fluids. These collectors 9 are shown in phantom in Fig.l so as not to overload the drawing.
Ainsi que représenté à la Fig. 2, chaque organe de liaison 10 des bords longitudinaux 2a des plaques 2 d'échange thermique est formé par un profilé en forme de T comportant une âme 11 et deux ailes 12 perpendiculaires à ladite âme 11.As shown in FIG. 2, each connecting member 10 of the longitudinal edges 2a of the heat exchange plates 2 is formed by a T-shaped profile comprising a core 11 and two wings 12 perpendicular to said core 11.
L'épaisseur de l'âme 11 est sensiblement égale à l'épaisseur d'une plaque 2 d'échange thermique et la hauteur de chaque aile 12 est sensiblement égale à un demi intervalle séparant deux plaques 2 d'échange thermique.The thickness of the core 11 is substantially equal to the thickness of a heat exchange plate 2 and the height of each wing 12 is substantially equal to a half interval separating two heat exchange plates 2.
L'âme 11 de chaque profilé 10 est fixée au bord longitudinal 2a de la plaque 2 d'échange thermique correspondante au moyen d'un cordon de soudure 13 continu et étanche et chacune des ailes 12 d'un profilé 10 est fixée à une aile 12 du profilé 10 adjacent au moyen d'un cordon de soudure 14 continu et étanche.The core 11 of each profile 10 is fixed to the longitudinal edge 2a of the corresponding heat exchange plate 2 by means of a continuous and sealed weld bead 13 and each of the wings 12 of a profile 10 is fixed to a wing 12 of the profile 10 adjacent by means of a continuous and sealed weld bead 14.
Ainsi, la juxtaposition des profilés 10 en forme de T et leur assemblage avec les plaques 2 d'é- change thermique et entre eux forme, sur chaque côté longitudinal du faisceau de plaques 1, une paroi pleine et étanche.Thus, the juxtaposition of the T-shaped profiles 10 and their assembly with the plates 2 of thermal change and between them forms, on each longitudinal side of the bundle of plates 1, a solid and sealed wall.
Selon une variante non représentée, chaque organe de liaison 10 des bords longitudinaux 2a des plaques 2 d'échange thermique peut être formé par un profilé formant deux T juxtaposés et comprenant une plaque et deux ailes parallèles dont l'intervalle correspond à un intervalle entre deux plaques 2 d'échange thermique.According to a variant not shown, each connecting member 10 of the longitudinal edges 2a of the heat exchange plates 2 can be formed by a profile forming two juxtaposed T and comprising a plate and two parallel wings whose interval corresponds to an interval between two heat exchange plates 2.
Chaque aile est destinée à être fixée au moyen d'un cordon de soudure continu et étanche sur le bord longitudinal 2a d'une plaque 2 d'échange thermique correspondante. Les bords de chaque plaque du profilé sont fixés sur le bord de la plaque du profilé adjacent au moyen d'un cordon de soudure continu et étanche pour former également une paroi pleine.Each wing is intended to be fixed by means of a continuous and sealed weld bead on the longitudinal edge 2a of a corresponding heat exchange plate 2. The edges of each profile plate are fixed to the edge of the adjacent profile plate by means of a continuous and sealed weld bead to also form a solid wall.
Ce mode de réalisation permet de diminuer le nombre de cordons de soudure de liaison des différents éléments entre eux.This embodiment makes it possible to reduce the number of weld beads connecting the various elements together.
Ainsi que représenté à la Fig. 3, chaque organe de liaison 20 des bords d'extrémité 2b des plaques 2 d'échange thermique est formé par un profilé en forme de L comportant deux branches perpendiculaires, respectivement 21 et 22.As shown in FIG. 3, each connecting member 20 of the end edges 2b of the heat exchange plates 2 is formed by an L-shaped profile comprising two perpendicular branches, respectively 21 and 22.
Chaque branche 21 possède une épaisseur sensiblement à l'épaisseur d'une plaque 2 d'échange thermique et chaque branche 22 à une hauteur sensiblement égale à un demi-intervalle séparant deux plaques 2 d'échange thermique.Each branch 21 has a thickness substantially the thickness of a heat exchange plate 2 and each branch 22 at a height substantially equal to a half-interval separating two heat exchange plates 2.
Pour chaque profilé 20, la branche 21 est fixée au bord d'extrémité 2b de la plaque 2 d'échange thermique correspondante au moyen d'un cordon de soudure 23 continu et étanche. D'autre part, chaque branche 22 d'un profilé 20 est fixée à l'une des branches 22 du profilé 20 adjacent au moyen d'un cordon de soudure 24 continu et étanche . Comme représenté à la Fig. 3, un intervalle sur deux est obturé par les profilés 20 en forme de L permettant ainsi de réaliser, à chaque extrémité du faisceau de plaques 1, une superposition alternée d'extrémités ouvertes 3 et fermées 4. Comme représenté sur les figures 2 et 4 , chaque organe de raccordement 30 des claques 2 d'échange thermique et des organes de liaison 10 et 20 entre eux comporte, d'une part, une plaque verticale 31 en forme d' équerre et, d'autre part, deux plaques 32 et 33 horizontales et parallèles, disposées sur la face interne des deux branches de la plaque verticale 31 en forme d' équerre .For each profile 20, the branch 21 is fixed to the end edge 2b of the corresponding heat exchange plate 2 by means of a continuous and sealed weld bead 23. On the other hand, each branch 22 of a profile 20 is fixed to one of the branches 22 of the adjacent profile 20 by means of a continuous and sealed weld bead 24. As shown in Fig. 3, one interval out of two is closed by the L-shaped profiles 20 thus making it possible to produce, at each end of the bundle of plates 1, an alternating superposition of open ends 3 and closed 4. As shown in FIGS. 2 and 4 , each connecting member 30 of the heat exchange plates 2 and the connecting members 10 and 20 between them comprises, on the one hand, a vertical plate 31 in the form of a square and, on the other hand, two plates 32 and 33 horizontal and parallel, arranged on the internal face of the two branches of the vertical plate 31 in the form of a square.
Ainsi, pour chaque organe de raccordement 30, la plaque verticale 31 couvre un intervalle de l'un des circuits et un demi-intervalle supérieur et un demi intervalle inférieur de l'autre circuit.Thus, for each connecting member 30, the vertical plate 31 covers an interval of one of the circuits and an upper half-interval and a lower half-interval of the other circuit.
Les bords latéraux de cnaque branche de la plaque verticale 31 en forme d'équerre sont jointifs et fixés par soudage, respectivement sur les extrémités libres des profilés 10 en forme de T adjacents et sur les extrémités libres des profilés 20 en forme de L adjacents et les bords libres de chaque plaque horizontale 32 et 33 sont fixés par soudage sur les bords des plaques 2 adjacentes d'échange thermique. Les bords longitudinaux des organes de raccordement 30 ainsi superposés sont soudés entre eux pour former une surface d'angle continu.The lateral edges of each branch of the vertical plate 31 in the form of a square are joined and fixed by welding, respectively on the free ends of the adjacent T-shaped profiles 10 and on the free ends of the adjacent L-shaped profiles 20 and the free edges of each horizontal plate 32 and 33 are fixed by welding to the edges of the adjacent heat exchange plates 2. The longitudinal edges of the connecting members 30 thus superimposed are welded together to form a surface of continuous angle.
Pour permettre alternativement l'entrée et la sortie des fluides A et B, le faisceau de plaques 1 comporte, au niveau de ses bords d'extrémité 2b, au moins un élément de raccordement 40 aux collecteurs 9.To alternately allow the entry and exit of fluids A and B, the bundle of plates 1 comprises, at its end edges 2b, at least a connecting element 40 to the collectors 9.
Ainsi que représenté sur les Figs . 5 et 6, l'élément de raccordement 40 est formé par une juxtaposi¬ tion de pièces 41 en forme de T comportant une âme 42 et deux ailes, respectivement 43 et 44.As shown in Figs. 5 and 6, the connecting element 40 is formed by a juxtaposition of parts 41 in the form of a T comprising a core 42 and two wings, respectively 43 and 44.
L'âme 42 possède une épaisseur sensiblement égale à l'épaisseur d'une plaque 2 d'échange thermique et chaque aile 43 et 44 a une hauteur sensiblement à un demi-intervalle séparant deux plaques 2 d'échange thermi- que.The core 42 has a thickness substantially equal to the thickness of a heat exchange plate 2 and each wing 43 and 44 has a height substantially at a half-interval separating two heat exchange plates 2.
L'âme 42 de chaque pièce 41 est fixée par soudage au bord de la plaque 2 d'échange thermique correspondante et chacune des ailes 43 et 44 est fixée par soudage à une aile 43 ou 44 de la pièce 41 adjacente. Les bords latéraux des pièces 41 sont reliés par soudage aux bords libres des profilés 20 en forme de L adjacents.The core 42 of each part 41 is fixed by welding to the edge of the corresponding heat exchange plate 2 and each of the wings 43 and 44 is fixed by welding to a wing 43 or 44 of the adjacent part 41. The lateral edges of the parts 41 are welded to the free edges of the adjacent L-shaped profiles 20.
Le faisceau de plaques 1 ainsi formé est placé dans une enceinte étanche, non représentée, résistant à la pression interne pour constituer un échangeur thermique .The bundle of plates 1 thus formed is placed in a sealed enclosure, not shown, resistant to internal pressure to constitute a heat exchanger.
L'assemblage d'un tel faisceau de plaques 1 est réalisé en équipant par soudage chaque plaque 2 d'échange thermique, avant la constitution de l'empilage, d'une part, des profilés 10 en forme de T sur les bords longitudinaux 2a des plaques 2 d'échange thermique et, d'autre part, des profilés 20 en forme de L sur les bords 2b d'extrémité desdites plaques 2 d'échange thermique. Les profilés 10 et 20 sont réalisés de façon à obtenir l'intervalle exigé par les ondulations des plaques 2 d'échange thermique et à permettre le raccorde¬ ment à la plaque 2 par soudage manuel ou automatique en bout à bout .The assembly of such a bundle of plates 1 is carried out by equipping each heat exchange plate 2 with welding, before the formation of the stack, on the one hand, T-shaped profiles 10 on the longitudinal edges 2a heat exchange plates 2 and, on the other hand, L-shaped profiles 20 on the end edges 2b of said heat exchange plates 2. The sections 10 and 20 are produced so as to obtain the interval required by the undulations of the heat exchange plates 2 and to allow connection to the plate 2 by manual or automatic butt welding.
Les coins des plaques 2 d'échange thermique sont équipés des organes de raccordement 30 et des éléments de raccordement 40 aux collecteurs 9. Les plaques 2 d'échange thermique pourvues de ces différents éléments sont alors empilées et l'étancheite de chaque circuit est obtenue par le soudage bout à bout de ces éléments qui se trouvent en vis à vis.The corners of the heat exchange plates 2 are equipped with connection members 30 and connection elements 40 to the collectors 9. The heat exchange plates 2 provided with these various elements are then stacked and the tightness of each circuit is obtained by the butt welding of these elements which are opposite.
Un tel mode d'assemblage réduit notablement le nombre de soudure à réaliser et de ce fait la masse de métal pour réaliser les différentes soudures.Such an assembly method significantly reduces the number of welds to be made and therefore the mass of metal to make the various welds.
Il en résulte automatiquement, d'une part, un gain sur les temps de soudage et, d'autre part, une diminution des contraintes résiduelles et des déforma¬ tions engendrées par l'énergie de soudage.This automatically results, on the one hand, in a gain on the welding times and, on the other hand, a reduction in the residual stresses and in the deformations caused by the welding energy.
De plus, en cas de fuite, la recherche de l'origine de la fuite est facilitée. D'autre part, un tel assemblage permet d'obtenir des circuits exempts de toutes zones de réten¬ tion des fluides. In addition, in the event of a leak, it is easier to find the origin of the leak. On the other hand, such an assembly makes it possible to obtain circuits free from any fluid retention zones.
