Description

la présente invention se rapporte à un échangeur de chaleur mixte du type utilisé pour obtenir un transfert calorifique entre trois fluides en mouvement sans contact de ces fluides entre eux, l'un de ces fluides étant gazeux.the present invention relates to a mixed heat exchanger of the type used to obtain a heat transfer between three fluids in movement without contact of these fluids with one another, one of these fluids being gaseous.

De tels échangeurs de chaleur sont connus et utilisés dans de nombreuses applications et se présentent sous des formes variées comportant de façon générale plusieurs enceintes séparées chacune par une paroi commune. Les fluides circulent respectivement dans chacune de ces enceintes à des températures différentes, un échange calorifique étant obtenu à travers les parois communes.Such heat exchangers are known and used in numerous applications and come in various forms generally comprising several enclosures each separated by a common wall. The fluids circulate respectively in each of these enclosures at different temperatures, a heat exchange being obtained through the common walls.

Ces échangeurs sont généralement constitués par deux tubes accolés, l'un servant à la circulation de l'eau de puisage, et l'autre à la circulation de l'eau de chauffage. Ces tubes traversent un faisceau d'ailettes et sont situés à la partie supérieure d'une chambre de combustion.These exchangers generally consist of two joined tubes, one used for the circulation of the drawing water, and the other for the circulation of the heating water. These tubes pass through a bundle of fins and are located at the top of a combustion chamber.

On connait également des échangeurs dans lesquels les deux circuits d'eau indépendants sont constitués par un tube comportant une cloison sensiblement diamétrale, réalisé en une seule pièce en métal fondu à haute conductibilité thermique.There are also known exchangers in which the two independent water circuits are constituted by a tube comprising a substantially diametrical partition, made in a single piece of molten metal with high thermal conductivity.

Pour atteindre des performances plus élevées et faciliter la fabrication tout en diminuant très notablement le prix de revient, l'invention propose un échangeur de chaleur réalisé à partir de deux tôles comportant chacune des ondulations et fixées par exemple par soudure de part et d'autre d'une paroi intermédiaire commune pour la formation de deux circuits d'eau indépendants.To achieve higher performance and facilitate manufacturing while significantly reducing the cost price, the invention provides a heat exchanger made from two sheets each having corrugations and fixed for example by welding on both sides a common intermediate wall for the formation of two independent water circuits.

Suivant une caractéristique principale de l'invention, le pas des ondulations de l'une des tôles est inférieur au pas des ondulations de l'autre tôle de façon à multiplier les points de contact avec la cloison intermédiaire.According to a main characteristic of the invention, the pitch of the corrugations of one of the sheets is less than the pitch of the corrugations of the other sheet so as to multiply the points of contact with the intermediate partition.

Suivant une autre caractéristique de l'invention, le nombre de tubes constituant le circuit d'eau sanitaire est plus important que le nombre de tubes formant le circuit d'eau de chauffage.According to another characteristic of the invention, the number of tubes constituting the domestic water circuit is greater than the number of tubes forming the heating water circuit.

D'autres oaractéristiques particulières et avantages de l'invention ressortiront de la description suivante dans laquelle on se réfère aux dessins annexés qui représentent :

  • - figure 1 : une vue en perspective d'une partie de l'échangeur selon l'invention ;
  • - figure 2 : une vue schématique en perspective de l'ensemble de l'échangeur ;
  • - figure 3 : une vue en perspective d'une variante de cet échangeur.
Other particular features and advantages of the invention will emerge from the following description in which reference is made to the appended drawings which represent:
  • - Figure 1: a perspective view of part of the exchanger according to the invention;
  • - Figure 2: a schematic perspective view of the entire exchanger;
  • - Figure 3: a perspective view of a variant of this exchanger.

On a représenté sur les figures 1 et 2 un échangeur de chaleur à trois fluides, l'un gazeux et les deux autres liquides. Cet échangeur est réalisé en fixant de chaque côté d'une paroi commune intermédiaire 2, deux tôles 10 et 20 comportant des ondulations longitudinales 11 et 21, pour obtenir une plaque échangeur désignée dans son ensemble par la référence 1. Les ondulations 11 forment avec la paroi 2, un premier réseau de tubes 12 pour la circulation de l'eau sanitaire L1 et les ondulations 21 forment également avec la paroi 2 un second réseau de tubes 22 indépendant pour la circulation de l'eau de chauffage L2.FIGS. 1 and 2 show a heat exchanger with three fluids, one gaseous and the other two liquids. This exchanger is produced by fixing on each side of an intermediate common wall 2, two sheets 10 and 20 comprising longitudinal corrugations 11 and 21, to obtain an exchanger plate designated as a whole by the reference 1. The corrugations 11 form with the wall 2, a first network of tubes 12 for circulation of sanitary water L 1 and the corrugations 21 also form, with wall 2, a second independent network of tubes 22 for circulation of heating water L 2 .

Selon un autre mode de réalisation connu en soi, la formation des deux réseaux de tubes 12 et 22 s'effectue par exemple de la manière suivante : on soude partiellement ensemble et face contre face, trois tôles planes en alliage d'aluminium ou en alliage inoxydable, et en laissant des bandes non soudées. Les tôles ainsi assemblées sont ensuite formées en exerçant directement une pression hydraulique à l'aide d'eau injectée entre elles aux endroits non soudés, on obtient ainsi les ondulations longitudinales 11 et 21. Ce produit, connu en soi, est particulièrement approprié pour mettre en oeuvre la présente invention, mais,il va de soi qu'on peut réaliser de toute autre manière les ondulations sans sortir du cadre de l'invention.According to another embodiment known per se, the formation of the two networks of tubes 12 and 22 is carried out for example in the following manner: three flat sheets made of aluminum alloy or alloy are partially welded together and face to face stainless, and leaving strips not welded. The sheets thus assembled are then formed by directly exerting hydraulic pressure with the aid of water injected therebetween at the non-welded locations, the longitudinal corrugations 11 and 21 are thus obtained. This product, known per se, is particularly suitable for placing implementing the present invention, but it goes without saying that the undulations can be produced in any other way without departing from the scope of the invention.

Comme représenté sur la figure 2, l'ensemble de l'échangeur est réalisé en superposant à une certaine distance les unes des autres plusieurs plaques 1 ainsi obtenues de telle manière que les gaz G qui sont par exemple les gaz de combustion d'un brûleur à gaz circulent entre ces plaques comme indiqué par les flèches.As shown in Figure 2, the entire exchanger is made by superimposing at a distance from each other several plates 1 thus obtained so that the gases G which are for example the combustion gases of a burner gas flow between these plates as indicated by the arrows.

En partant d'une plaque 1, il est également possible de former un échangeur à spirale à l'intérieur duquel circulent les gaz chauds ou encore un échangeur de forme générale parallélépipédique dans lequel les gaz chauds sont amenés à effectuer un cheminement particulier le long de ladite plaque.Starting from a plate 1, it is also possible to form a spiral exchanger inside which the hot gases circulate or else an exchanger of generally parallelepiped shape in which the hot gases are brought to carry out a particular path along said plate.

Pour améliorer les échanges thermiques entre les trois fluides, le pas des ondulations 11 de la tôle 10 est inférieur au pas des ondulations 21 de la tôle 20 ce qui permet de multiplier les bandes de contact 13 entre la tôle 10 et la paroi intermédiaire 2 afin d'augmenter la surface active d'échange thermique. Les deux tôles 10 et 20 jouent le rôle d'échangeur gaz-eau et la paroi intermédiaire 2 forme une ailette d'échange thermique eau-eau.To improve the heat exchanges between the three fluids, the pitch of the corrugations 11 of the sheet 10 is less than the pitch of the corrugations 21 of the sheet 20 which makes it possible to multiply the contact strips 13 between the sheet 10 and the intermediate wall 2 so increase the active heat exchange surface. The two sheets 10 and 20 play the role of gas-water exchanger and the intermediate wall 2 forms a water-water heat exchange fin.

En effet, les gaz chauds G, circulant de part-et d'autre de la plaque 1, chauffent les deux tôles 10 et 20 et les fluides caloporteurs L1 et L2. Si par exemple le fluide L1 est statique et le fluide L2 dynamique, les calories en provenance de la tôle 10 se transfèrent à la paroi intermédiaire 2 étant donné le nombre élevé de bandes de contact 13 et viennent s'ajouter au fluide L2. De plus, l'eau étant un très mauvais conducteur thermique, les calories du fluide L2 en mouvement, sont ramenées sur la paroi intermédiaire commune 2 car le fluide L1 n'étant pas en circulation forme isolant ce qui permet d'augmenter la température du fluide L2.In fact, the hot gases G, circulating on either side of the plate 1, heat the two sheets 10 and 20 and the heat transfer fluids L 1 and L 2 . If for example the fluid L 1 is static and the fluid L 2 dynamic, the calories coming from the sheet 10 are transferred to the intermediate wall 2 given the high number of contact strips 13 and are added to the fluid L 2 . In addition, water being a very poor thermal conductor, the calories of the fluid L 2 in movement, are brought back to the common intermediate wall 2 because the fluid L 1 not being in circulation insulating form which makes it possible to increase the fluid temperature L 2 .

Dans le cas inverse où le fluide L1 est dynamique et le fluide L2 statique le même phénomène se reproduit.In the opposite case where the fluid L 1 is dynamic and the fluid L 2 static, the same phenomenon is reproduced.

D'autre part, le diamètre des tubes 12 et 22 étant relativement faible, les lames d'eau ainsi créées sont minces ce qui augmente la vitesse de circulation des deux fluides pour un débit donné et facilite par conséquent les échanges thermiques.On the other hand, the diameter of the tubes 12 and 22 being relatively small, the water layers thus created are thin which increases the speed of circulation of the two fluids for a given flow rate and consequently facilitates heat exchanges.

Cette disposition permet donc d'obtenir un échangeur extrêmement performant même dans le cas où l'un des fluides n'est pas en mouvement.This arrangement therefore makes it possible to obtain an extremely efficient exchanger even in the case where one of the fluids is not in motion.

Comme représenté sur la figure 3, des ailettes longitudinales 3 peuvent être rapportées sur les bandes de contact 13 entre chaque ondulation 11 de la tôle 10 afin d'augmenter encore la conductibilité thermique de l'ensemble.As shown in Figure 3, longitudinal fins 3 can be attached to the contact strips 13 between each corrugation 11 of the sheet 10 in order to further increase the thermal conductivity of the assembly.

Suivant une autre variante de l'invention, la plaque intermédiaire 2 peut comporter des motifs en relief pour ramener les calories d'un circuit sur l'autre.According to another variant of the invention, the intermediate plate 2 may include raised patterns to bring the calories from one circuit to the other.

Sans sortir du cadre de l'invention, il est possible de remplacer les ondulations de chaque tôle par des motifs répétitifs en relief ou en creux, et décalés de façon à diviser le courant de circulation du fluide. Il est également possible d'utiliser des tôles formées à partir de deux bandes de matériaux différents par exemple du cuivre en contact avec l'eau et de l'acier inoxydable en contact avec les gaz chauds.Without departing from the scope of the invention, it is possible to replace the corrugations of each sheet by repetitive patterns in relief or in hollow, and offset so as to divide the circulation current of the fluid. It is also possible to use sheets formed from two strips of different materials, for example copper in contact with water and stainless steel in contact with hot gases.
