Description
La présente invention se rapporte à un échangeur thermique constitué d'au moins un tube porteur, dit premier tube, et d'une pluralité de tubes portés, dits seconds tubes, lesdits seconds tubes étant liés perpendiculairement audit premier tube, la liaison entre un second tube et ledit premier tube étant effectuée par un agencement de liaison comportant une pièce de liaison soudée audit premier tube et, pour chaque second tube, une partie de liaison soudée audit second tube.The present invention relates to a heat exchanger consisting of at least less a carrier tube, called the first tube, and a plurality of carried tubes, called second tubes, said second tubes being connected perpendicular to said first tube, the connection between a second tube and said first tube being effected by a connection arrangement comprising a connection piece welded to said first tube and, for each second tube, a connecting part welded to said second tube.
Le document US-A-3265044 décrit un tel échangeur thermique.Document US-A-3265044 describes such a heat exchanger.
Dans ce document, la pièce de liaison est une pièce référencée 25 soudée au tube référencé 17. Cette pièce 25 est assez épaisse, épouse l'arrondi du tube 17 et possède une lèvre supérieure 30 et une lèvre inférieure 32. Il existe autant de pièces 25 que de tubes perpendiculaires 27 à lier à un tube 17. Au tube perpendiculaire 17 est soudée une partie de liaison référencée 28, 29 venant s'accrocher aux lèvres 30 et 32.In this document, the connecting part is a part referenced 25 welded to the tube referenced 17. This part 25 is fairly thick, conforms to the rounding of the tube 17 and has an upper lip 30 and a lower lip 32. There are as many 25 pieces than perpendicular tubes 27 to be linked to a tube 17. To the tube perpendicular 17 is welded a connecting part referenced 28, 29 coming hang on to lips 30 and 32.
Dans un tel agencement, les pièces de liaison 25 sont nombreuses et massives. Par ailleurs, lors des différents cycles de fonctionnement, compte tenu des dilatations, les tubes 27, liés aux parties de liaison 28, 29, coulissent dans la pièce de liaison 25 et peuvent s'en échapper sauf à prévoir des lèvres longues.In such an arrangement, the connecting pieces 25 are numerous and massive. Furthermore, during the various operating cycles, taking into account dilations, the tubes 27, linked to the connecting parts 28, 29, slide in the connecting piece 25 and can escape therefrom unless providing long lips.
La présente invention propose une solution plus simple n'utilisant pas une pluralité de pièces de liaison telle que celle référencée 25 du document cité, permettant un certain coulissement longitudinal des tubes, mais en excluant la possibilité d'un déboítement.The present invention provides a simpler solution not using a plurality of connecting pieces such as that referenced 25 of the cited document, allowing a certain longitudinal sliding of the tubes, but excluding the possibility of dislocation.
L'invention a ainsi pour objet un échangeur thermique tel que défini ci-dessus, caractérisé en ce que ladite pièce de liaison est unique et constituée d'un simple profilé plat soudé le long d'une génératrice dudit premier tube, ledit profilé présentant des découpes de réception desdites parties de liaison, un blocage radial desdits seconds tubes étant assuré par des formes complémentaires de la partie de liaison et de la découpe, et en ce que chaque partie de liaison comporte des moyens de butée longitudinale dans au moins un sens. The subject of the invention is therefore a heat exchanger as defined above, characterized in that said connecting piece is unique and consists of a simple flat section welded along a generator of said first tube, said section having cutouts for receiving said connecting parts, a radial locking of said second tubes being insured by complementary forms of the connecting part and of the cut, and in that each connecting part comprises longitudinal stop means in at least one direction.
Avantageusement lesdites formes complémentaires sont en queue d'aronde.Advantageously said complementary shapes are dovetailed.
Selon une première variante, le blocage longitudinal est réalisé par une barrette de butée portée par la partie de liaison.According to a first variant, the longitudinal blocking is made by a stop bar carried by the part link.
Avantageusement, dans ce cas, la partie de liaison est constituée d'une pièce métallique qui a une forme de C, avec sur une de ses faces, centré sur l'axe de symétrie de cette pièce, un berceau destiné à recevoir le second tube et sur ses branches des parties de blocage de section transversale en queue d'aronde et sur l'autre face de la pièce, sur l'âme, ladite barrette de butée.Advantageously, in this case, the connecting part is consisting of a metal part which has a C shape, with on one of its faces, centered on the axis of symmetry of this piece, a cradle intended to receive the second tube and on its branches cross-section locking parts dovetailed and on the other side of the room, on the core, said stop bar.
Selon une seconde variante, le blocage longitudinal est réalisé par une forme arrondie de la partie de liaison dans la direction longitudinale du second tube.According to a second variant, the longitudinal blocking is achieved by a rounded shape of the connecting part in the longitudinal direction of the second tube.
Avantageusement, dans ce cas, la partie de liaison est constituée d'une pièce métallique qui a une forme de O, avec sur une de ses faces, centré sur l'axe de symétrie horizontal de cette pièce, un berceau destiné à recevoir le second tube et sur ses branches horizontales, des parties de blocage de section transversale en queue d'aronde et avec sur l'autre face de la pièce, ladite forme arrondie en arc de cercle.Advantageously, in this case, the connecting part is consisting of a metal part which has an O shape, with on one of its faces, centered on the axis of symmetry horizontal of this part, a cradle intended to receive the second tube and on its horizontal branches, parts of cross section locking in dovetail and with on the other face of the part, said rounded arc shape of circle.
Avantageusement, ledit profilé est un profilé plat soudé de façon automatique le long d'une génératrice du premier tube.Advantageously, said profile is a flat profile automatically welded along a generator of the first tube.
De préférence, le premier tube est vertical et porteur et le second tube est horizontal et porté.Preferably, the first tube is vertical and carrying and the second tube is horizontal and carried.
