Abstract
Description
La présente invention concerne des dispositifs pour lier mécaniquement lesThe present invention relates to devices for mechanically linking the
éléments constituant des échangeurs thermiques, des filtres, des systèmes de dé coalescence pour fluides chargés, de supports de matières catalytiques. elements constituting heat exchangers, filters, coalescence systems for charged fluids, supports for catalytic materials.
Tous ces matériels sont en général constitués par des ailettes plates ou plissées, assemblées à des 5- plaques lisses ou tubulaires par soudages au four à atmosphère contrôlée ou sous vide, par l'intermédiaire de soudobrasages, par soudages aux points de contacts par soudage électrique par résistance, par liaisons ponctuelles par laser. Ces techniques sont parfaitement connues et réclament des procédés complexes et des moyens industriels adaptés à l'importance des séries demandées, ce qui entraîne des coûts élevés de production. All these materials are generally constituted by flat or folded fins, assembled to smooth or tubular 5-plates by soldering in a controlled atmosphere furnace or under vacuum, by means of brazing, by welding at the points of contact by electric welding by resistance, laser point connections. These techniques are well known and require complex processes and industrial means adapted to the importance of the requested series, resulting in high production costs.
10- Les appareils concernés peuvent être constitués par l'empilage de constituants plats, ailettes plissées séparées par des éléments lisses pour éviter l'imbrication des plis des ailettes (figure 1) ou par enroulage d'ailettes plissées sur un feuillard lisse pour assurer leur séparation (figure 2). Ces éléments constitutifs doivent subir mie opération de liaison par soudage ou brasage afin d'en assurer des ensembles monolithiques qui seront utilisés dans leur fonctions propres. 15- L'invention par modifications de l'élément lisse séparateur des ailettes plissées, supprime toutes les opérations d'assemblage par soudage en créant une liaison mécanique. 10- The devices concerned may be constituted by the stacking of flat components, pleated fins separated by smooth elements to avoid nesting of the folds of the fins (Figure 1) or by winding pleated fins on a smooth strip to ensure their separation (Figure 2). These constituent elements must undergo a binding operation by welding or brazing to ensure monolithic assemblies that will be used in their own functions. 15- The invention by modifications of the smooth separator element of the pleated fins, eliminates all welding assembly operations by creating a mechanical connection.
La liaison des pièces constitutives est obtenue par la présence de "lanières" disposées sur les rives du séparateur lisse qui interdit le déplacement transversal des ailettes plissées (figure 3). Ces "lanières" sont obtenues par un train de molettes de fendage et formage des ondulations. 20- Le pas de ces ondulations sera de 1, 3 à 1,7 fois le pas des plis des ailettes afin de toujours se placer dans des zones verticales ou faiblement inclinées des plis. La hauteur des ondulations sera de 0,5 fois la hauteur des plis des ailettes. L'épaisseur du feuillard sera de 0,03 à 0,06 mm, la largeur des lanières sera de 1 à 2 mm ceci ne provoquera pas de pertes de charge notables sur le fluide traversant et pourra même être à l'origine de la diminution de la couche limite. 25L'utilisation de molettes de formage et fendage ne provoque pas de chutes de métal et rend de ce fait, la maintenance des outillages facile. The connection of the constituent parts is obtained by the presence of "strips" arranged on the edges of the smooth separator which prohibits the transverse displacement of the pleated fins (Figure 3). These "thongs" are obtained by a train of splitting wheels and forming corrugations. 20- The pitch of these undulations will be from 1, 3 to 1.7 times the pitch of the folds of the fins to always be placed in vertical areas or slightly inclined folds. The height of the corrugations will be 0.5 times the height of the folds of the fins. The thickness of the strip will be 0.03 to 0.06 mm, the width of the strips will be 1 to 2 mm this will not cause significant pressure drops on the fluid through and may even be at the origin of the decrease of the boundary layer. 25The use of forming and splitting wheels does not cause metal scrap and makes maintenance of tools easy.
Il peut être envisagé de placer sur les ailettes plissées des découpes soit par molettes de formage soit par outils spécifiques afin de placer le feuillard lisse et solidariser les éléments dans le plan transversal (figure 4). Cette solution est surtout recommandée pour l'utilisation d'ailettes plissées 30- planes et empilées (figure 1). It may be envisaged to place on the pleated fins cutouts either by forming wheels or by specific tools in order to place the strip smooth and secure the elements in the transverse plane (Figure 4). This solution is especially recommended for the use of flat and stacked pleated fins (FIG. 1).
Les éléments (ailettes plissées et séparateurs plans) sont placés dans des viroles de formes appropriées (ovales, rondes ou rectangulaires). Le feuillard séparateur aura son extrémité soudée TIG ou Laser dans la fente pour fermeture de la virole, ce qui rendra l'ensemble monolithique. The elements (pleated fins and planar separators) are placed in ferrules of appropriate shapes (oval, round or rectangular). The separator strip will have its TIG or laser welded end in the slot for closing the ferrule, which will make the whole monolithic.
