Description
La présente invention concerne un échangeur de chaleur ainsi qu'une chaudière tubulaire munie d'un tel échangeur de chaleur du type défini dans le préambule de la première revendication.The present invention relates to a heat exchanger and a tubular boiler provided with such a heat exchanger of the type defined in the preamble to the first claim.
On connaît déjà un tel échangeur (FR-A-2 103 583). Mais cet échangeur connu, destiné au passage de fluides chimiques, corrosifs ne peut être utilisé comme échangeur de chaleur dans des chaudières car même si l'on fait abstraction des problèmes de tenue en température et en pression, puisqu'il est réalisé en matière plastique, ces plateaux ne constituent que l'une des parties de l'échangeur (le bloc échangeur) comprenant par ailleurs un carter qui entoure les plateaux et assure les fonctions d'étanchéité, de circulation des fluides et de branchement d'arrivée et de sortie des fluides.Such an exchanger is already known (FR-A-2 103 583). However, this known exchanger, intended for the passage of corrosive chemical fluids, cannot be used as a heat exchanger in boilers because even if one disregards the problems of resistance to temperature and pressure, since it is made of plastic material , these plates constitute only one of the parts of the exchanger (the exchanger block) further comprising a casing which surrounds the plates and performs the functions of sealing, circulation of fluids and connection of inlet and outlet fluids.
Cet échangeur est relativement compliqué et ne permet pas une réalisation modulaire puisque le carter définit les limites de l'échangeur.This exchanger is relatively complicated and does not allow modular construction since the casing defines the limits of the exchanger.
La présente invention a pour but de créer un échangeur de chaleur adaptable à des chaudières de puissance très différente et qui puisse, même après installation, être modifié par exemple pour être adapté à une puissance supérieure.The present invention aims to create a heat exchanger adaptable to boilers of very different power and which can, even after installation, be modified for example to be adapted at a higher power.
A cet effet, l'invention concerne un échangeur de chaleur du type défini ci-dessus, caractérisé par les caractéristiques de la première revendication.To this end, the invention relates to a heat exchanger of the type defined above, characterized by the features of the first claim.
Comme les éléments échangeurs de chaleur sont tous identiques et servent au passage d'un premier fluide, leur empilage servant au passage du second fluide, il est possible par le choix d'un nombre approprié d'éléments échangeurs de chaleur de réaliser un échangeur de chaleur d'une puissance quelconque adapté à n'importe quelle puissance de chaudière.As the heat exchanger elements are all identical and serve for the passage of a first fluid, their stacking serving for the passage of the second fluid, it is possible by the choice of an appropriate number of heat exchanger elements to produce a heat exchanger heat of any power suitable for any boiler power.
Même dans une installation déjà réalisée, il est possible si la puissance de la chaudière doit être augmentée, d'augmenter également les dimensions de l'échangeur de chaleur en fonction de cette nouvelle puissance.Even in an installation already carried out, it is possible if the power of the boiler must be increased, also to increase the dimensions of the heat exchanger according to this new power.
La fabrication de l'échangeur de chaleur selon l'invention est extrêmement simple puisque l'échangeur se compose d'éléments simplement empilés et fermés sur leur côté et, d'autre part, les éléments eux-mêmes sont d'une fabrication extrêmement simple puisqu'ils se composent d'un nombre réduit de pièces fabriquées par matriçage ou par coulée et qui sont réunis par des soudures.The manufacture of the heat exchanger according to the invention is extremely simple since the exchanger consists of elements simply stacked and closed on their side and, on the other hand, the elements themselves are of an extremely simple manufacture since they consist of a reduced number of parts produced by die-casting or by casting and which are joined by welds.
Suivant une autre caractéristique de l'invention, la plaque principale comporte des retours le long de deux bords parallèles pour former des entretoises d'écartement, ces bords étant rabattus et la plaque auxiliaire comporte des retours pour être soudée dans la plaque principale en retrait des retours des bords parallèles.According to another characteristic of the invention, the main plate has returns along two parallel edges to form spacers, these edges being folded down and the auxiliary plate has returns to be welded into the main plate set back from the returns from parallel edges.
Cette réalisation de l'élément échangeur de chaleur entoure, grâce au retour de la plaque principale, le chemin suivi par le second fluide (fumée).This embodiment of the heat exchanger element surrounds, thanks to the return of the main plate, the path followed by the second fluid (smoke).
Suivant une autre caractéristique de l'invention, les plaques principale et auxiliaire sont embouties.According to another characteristic of the invention, the main and auxiliary plates are stamped.
Suivant une autre caractéristique de l'invention, les déformations des plaques correspondent à une section ondulée, complémentaire pour la plaque principale et la plaque auxiliaire, et les entretoises sont fixées aux plaques dans les creux en regard, séparant les ondulations.According to another characteristic of the invention, the deformations of the plates correspond to a corrugated section, complementary to the main plate and the auxiliary plate, and the spacers are fixed to the plates in the recesses opposite, separating the corrugations.
Il est également avantageux de réaliser une chaudière à laquelle est intégré un élément échangeur de chaleur selon l'invention. Cet élément peut constituer la surface inférieure de la chaudière ou le dessus de celle-ci.It is also advantageous to produce a boiler in which a heat exchanger element according to the invention is integrated. This element can constitute the bottom surface of the boiler or the top of it.
Une telle chaudière, grâce à sa structure formée de panneaux, est également d'une réalisation extrêmement simple, par assemblage soudé.Such a boiler, thanks to its structure formed of panels, is also of an extremely simple embodiment, by welded assembly.

Selon les figures 1, 2, 3, un élément d'échangeur de chaleur se compose d'une plaque principale (plaque supérieure) 1 et d'une plaque auxiliaire (plaque inférieure) 2 définissant entre elles le tube ou le chemin de circulation du fluide caloporteur (eau). Ce chemin est complété à une extrémité par un collecteur d'entrée/sortie 3, 4 communiquant avec la première branche 5 du chemin de circulation du fluide.According to Figures 1, 2, 3, a heat exchanger element consists of a main plate (upper plate) 1 and an auxiliary plate (lower plate) 2 defining between them the tube or the circulation path of the heat transfer fluid (water). This path is completed at one end by an inlet /
Cette pièce 3, 4, comporte des brides supérieure et inférieure 6, 7, pour réunir des éléments d'échangeur.This
Chacun des éléments 3, 4, est une pièce par exemple en acier moulé définissant une chambre. A leur autre extrémité les plaques 1, 2, sont réunies par un bord 8. Les plaques comportent à chaque coin correspondant un prolongement de manière à définir entre le bord 8 et l'extrémité gauche de l'échangeur un passage pour le second fluide, qui, venant par exemple de-dessous l'élément échangeur représenté à la figure 1, passe par-dessus celui-ci en tournant au niveau de la fenêtre 11. A l'avant, le prolongement 9, qui peut ou non recevoir le premier fluide en communiquant avec le chemin 5, comme cela est représenté, comporte une gorge 10 qui est alignée avec les gorges des autres éléments d'échangeur placés par-dessus et sert à recevoir un joint ainsi que la cloison fermant l'échangeur à cette extrémité.Each of the
Au niveau de l'autre extrémité l'échangeur est fermé latéralement par la superposition des collecteurs 3, 4, et le passage du second fluide se fait par le dégagement 12 subsistant entre le bord droit 13 des plaques et l'élément de collecteur 3, 4.At the other end, the exchanger is closed laterally by the superposition of the
Une telle disposition permet de conduire le fluide caloporteur de manière que celui-ci parcourt les éléments échangeurs soit en série, soit en parallèle, soit suivant une combinaison mixte série-parallèle. Pour cela, on utilise des coupelles de distribution ou d'obturation situées au niveau des raccordements ou entre les raccordements des collecteurs 3, 4. Cette disposition permet également de modifier ou d'adapter le nombre de plaques empilées afin d'adapter la puissance et le rendement des chaudières.Such an arrangement makes it possible to conduct the heat transfer fluid so that it traverses the exchanger elements either in series, or in parallel, or in a mixed series-parallel combination. For this, use is made of distribution or closure cups located at the connections or between the connections of the
Ces coupelles ne sont pas représentées dans les dessins. Ces coupelles permettent d'assurer une obturation partielle ou totale de la communication entre deux collecteurs 3, 4.These cups are not shown in the drawings. These cups make it possible to ensure partial or total sealing of the communication between two
Les figures 1 et 2 montrent également les déformations allongées, de section courbe 14, 15, de la plaque supérieure et de la plaque inférieure qui délimitent les chemins de passage du premier fluide. Certains des bossages 14, 15, sont séparés par une entretoise 16 à laquelle les plaques 1, 2, sont par ailleurs soudées.FIGS. 1 and 2 also show the elongated deformations, of
Les différents éléments constituant l'élément d'échangeur sont réunis entre eux par des soudures.The various elements constituting the exchanger element are joined together by welds.
La vue en coupe transversale partielle représentée à la figure 3 montre la structure d'un élément d'échangeur selon l'invention. Cet élément se compose des plaques principale et auxiliaire 1, 2, présentant des ondulations 14, 15. Cette figure laisse également apparaître deux entretoises 16, 16′. Ces entretoises sont soudées à la plaque supérieure 1, directement et la liaison avec la plaque inférieure 2 se fait à travers des perçages 17 réalisés dans les ondulations de la plaque inférieure 2 et à travers lesquels on soude les entretoises 16, 16′ à la plaque 2.The partial cross-section view shown in FIG. 3 shows the structure of an exchanger element according to the invention. This element consists of the main and
Selon la figure 3, la plaque principale 1 ou plaque supérieure, selon l'orientation représentée, comporte un bord deux fois replié selon ses parties 18, 19 pour former un retour 19. Le bord 19A de ce retour est soudé par une soudure 21 à l'arête 20A du bord 20 de la plaque auxiliaire ou plaque inférieure 2.According to FIG. 3, the main plate 1 or upper plate, according to the orientation shown, has an edge twice folded along its
La partie à droite de l'élément d'échangeur selon la figure 3 a une forme symétrique de celle de la partie gauche représentée de manière explicite. (cette forme apparaît d'ailleurs à la figure 4).The right part of the exchanger element according to Figure 3 has a symmetrical shape to that of the left part shown explicitly. (this shape also appears in Figure 4).
Selon la figure 3, la plaque supérieure 1 a la forme d'une boîte renversée dans laquelle on place la plaque auxiliaire 2. Pour la fabrication, une fois les plaques 1 et 2 mises en forme, on soude sur la plaque supérieure 1, sur son côté intérieur, les entretoises 16, 16′ par les cordons de soudure 22, 23 puis à travers les perçages 17 on soude des bouchons 24 qui solidarisent la plaque inférieure aux entretoises 16. La plaque inférieure 2 est également reliée par le cordon de soudure 21.According to Figure 3, the upper plate 1 has the shape of an inverted box in which one places the
La figure 4 montre l'empilage de deux éléments échangeurs 30, 31, qui définissent entre eux un ou des passages 32 pour le second fluide. L'écartement est assuré par les bords des éléments ainsi empilés.FIG. 4 shows the stacking of two
Les figures 5 et 6 montrent de manière séparée et détaillée la forme d'un demi-collecteur.Figures 5 and 6 show separately and in detail the shape of a half-collector.
L'élément d'échangeur de chaleur selon les figures 1 et 2 comporte à l'une de ses extrémités deux demi-collecteurs, l'un pour l'arrivée du premier fluide, l'autre pour le départ du premier fluide. Ces éléments sont identiques à l'élément représenté aux figures 5 et 6. L'un des éléments est utilisé dans la position représentée à la figure 5, l'autre est utilisé dans la position renversée.The heat exchanger element according to Figures 1 and 2 comprises at one of its ends two half-manifolds, one for the arrival of the first fluid, the other for the departure of the first fluid. These elements are identical to the element shown in Figures 5 and 6. One of the elements is used in the position shown in Figure 5, the other is used in the inverted position.
Comme déjà indiqué, ces éléments se composent d'un cylindre d'arrivée 40 muni de deux brides 41, 42, à perçage 43 pour l'assemblage des éléments entre eux. Le cylindre 40 communique par un conduit 44 avec une chambre 45 débouchant dans un manchon 46. Le manchon 46 est relié aux plaques supérieure et inférieure de l'élément d'échangeur. L'extrémité gauche, selon la figure 5, de la chambre 45 est fermée par une cloison 47.As already indicated, these elements consist of an
