Definitions
- the present invention relates to a device for attaching a panel of horizontal or gently sloping heat exchanger tubes to vertical tubes or beams provided with longitudinal fins.
- Figure 1 shows in profile some horizontal tubes of a panel fixed on the shoulders of the fins of a vertical tube, and a part forming a latch and a jumper separated from the device.
- FIG. 2 shows in exploded perspective two tube supports, with parts forming a latch and jumpers, corresponding to the upper part of the device of FIG. 1.
- FIG. 3 represents in profile view a few tubes, including two pairs of spacing greater than that of the others, corresponding to different parts of the panel, and the parts forming the corresponding latch.
- the vertical tube 1 comprises opposite welded vertical fins 2. On these fins are cut by punching notches such as 3, separating shoulders 4 with rim 5 projecting upwards.
- the latch 6 has a substantially flat upper face 7 on the side facing the vertical support tube, and rising on the other side according to a cylinder with a radius of curvature equal to that of a horizontal tube such as 8, so assuming that the horizontal tube hangs outwards.
- the width of the upper face 7 is determined in conjunction with the depth of the notches 3 so that the tubes in place come into contact with the bottom of the notches.
- the latch part is provided with a spout 9 separated from the middle part by a hollow 10 of width corresponding to that of the rim 5 of a shoulder 4, so as to be fit exactly on this one.
- It also includes a vertical sole 11 intended to be applied against the rim of the shoulder 4, pierced in its lower part with a rectangular hole 12, and comprising on each side of this hole wings 13 intended to be applied on both sides of the shoulders 4.
- These holes 12 are intended to allow the introduction of jumpers 14, which once placed in position come to rest by their legs on the upper periphery of the immediately lower horizontal tube.
- An upper lateral edge 15 of these jumpers is sufficiently pronounced to come into abutment on the lower part 16 of the corresponding shoulder, and thus to block the corresponding tube in the event of upward bias which would tend to unhook it during the setting in place.
- the jumpers 14 are no longer necessary for holding the tubes of the panel in place. They can be made of a combustible material at the temperature of the combustion gases coming into contact with the tube panel, and for example of plastic material.
- FIG. 3 represents a device for hooking tubes similar to that of FIGS. 1 and 2, but in an area where two adjacent tubes have a spacing greater than that of the other tubes, corresponding for example to the limit between two different parts of the panel of tubes.
- the parts forming a latch 6 are replaced at this height by parts 6 A, comprising longer vertical shoes 11A, pressing against the shoulder flange 3A.
- Jumpers 14, identical to the others, are engaged in the holes 12, identical to those of the other parts forming a latch, of the parts 6A.
- the invention applies to the attachment of any panel of horizontal or slightly inclined, straight or helical heat exchanger tubes at low pitch.

Abstract
Description
La présente invention concerne un dispositif d'accrochage d'un panneau de tubes d'échangeur de chaleur horizontaux ou à faible pente sur des tubes ou poutres verticaux munis d'aillettes longitudinales.The present invention relates to a device for attaching a panel of horizontal or gently sloping heat exchanger tubes to vertical tubes or beams provided with longitudinal fins.
On a déjà fixé de tels panneaux à l'aide de colliers formés autor des tubes portés et soudés sur les tubes ou les poutres verticaux; ou à l'aide de selles monoblocs placées entre les tubes ou les poutres-support et les tubes portés et soudés sur ceux-ci; ou à l'aide d'entretoises formées de deux parties coulissant l'une dans l'autre, l'une de ces parties étant soudée aux tubes ou poutres verticaux, l'autre partie étant soudée aux tubes portés.We have already fixed such panels using collars formed autor tubes carried and welded on the tubes or vertical beams; or using monobloc saddles placed between the tubes or the support beams and the tubes carried and welded thereon; or using spacers formed from two parts sliding one inside the other, one of these parts being welded to vertical tubes or beams, the other part being welded to the carried tubes.
De tels dispositifs d'accrochage nécessitent une préparation soignée du panneau sur gabarit et éventuellement un grand nombre d'opérations de soudage. Les pièces de liaison formées entre les tubes ou poutres verticaux et les tubes horizontaux comportent souvent des sections de contact relativement faibles avec les tubes horizontaux, de sorte qu'elles sont alors mal refroidies par le fluide circulant dans ceux-ci et que peuvent apparaître des contraintes thermiques excessives à la liaison pièce-tube pouvant entraîner la rupture du tube. De plus, s'il y a des vibrations en fonctionnement dans le panneau de tubes, il y a des concentrations de contraintes aux liaisons rigides entre tubes portés et support, ce qui peut entraîner des ruptures de tubes.Such attachment devices require careful preparation of the panel on the template and possibly a large number of welding operations. The connecting parts formed between the vertical tubes or beams and the horizontal tubes often have relatively small contact sections with the horizontal tubes, so that they are then poorly cooled by the fluid circulating in them and that may appear excessive thermal stresses on the part-tube connection which can cause the tube to rupture. In addition, if there are vibrations in operation in the tube panel, there are concentrations of stresses on the rigid connections between the supported tubes and the support, which can lead to tube ruptures.
La présente invention a pour but de remédier à ces inconvénients, et de procurer un dispositif d'accrochage de tels panneaux de tubes qui ne nécessite pas un positionnement très soigné des tubes sur gabarit, qui se prête à une fixation simple et rapide, pratiquement sans aucune opération de soudure, et qui permette l'emploi de pièces intermédiaires relativement simples et ne nécessitant pas une grande précision de fabrication. Le dispositif selon l'invention est caractérisé en ce qu'il comprend:
- a) sur les ailettes longitudinales de chaque tube ou poutre verticaux une série d'épaulements à rebord en saillie vers le haut,
- b) une série de pièces formant loquet présentant une face supérieure sensiblement plane d'un côté et se relevant de l'autre côté selon un cylindre de rayon de courbure égal ou légèrement supérieur à celui du rayon d'un tube horizontal, comportant sous le côté sensiblement plan de la face supérieure un bec séparé de la partie médiane par un creux s'emboîtant sur le rebord en saillie d'un épaulement, une semelle verticale dans un plan à 90° du plan de symétrie vertical de ladite pièce, de hauteur voisine de la hauteur du rebord de l'épaulement et percée dans le bas d'un trou d'axe perpendiculaire à son plan,
- c) une série de cavaliers de dimensions telles qu'ils puissent être installés dans lesdits trous des pièces formant loquet, comportant chacun des jambages de hauteur telle que leurs extrémités viennent au contact de la partie supérieure d'un tube horizontal reposant sur la face supérieure de la pièce formant loquet immédiatement inférieure, et un rebord latéral dans leur partie supérieure tel qu'une sollicitation vers le haut l'amène en butée contre la face inférieure de l'épaulement sur lequel est accrochée la pièce formant loquet dans le trou de laquelle il est engagé.
- a) on the longitudinal fins of each vertical tube or beam, a series of shoulders with upwardly projecting flanges,
- b) a series of parts forming a latch having a substantially planar upper face on one side and rising on the other side according to a cylinder with a radius of curvature equal to or slightly greater than that of the radius of a horizontal tube, comprising under the substantially flat side of the upper face, a spout separated from the middle part by a recess fitting onto the protruding rim of a shoulder, a vertical sole in a plane at 90 ° to the vertical plane of symmetry of said piece, of height close to the height of the rim of the shoulder and drilled in the bottom of an axis hole perpendicular to its plane,
- c) a series of jumpers of dimensions such that they can be installed in said holes of the parts forming a latch, each comprising legs of a height such that their ends come into contact with the upper part of a horizontal tube resting on the upper face of the immediately lower latch piece, and a lateral flange in their upper part such that an upward bias brings it into abutment against the underside of the shoulder on which the latch piece is hung in the hole of which he is engaged.
Il répond en outre de préférence à au moins l'une des caractéristiques suivantes:
- - L'espacement vertical de deux épaulements, la largeur de la partie externe cylindrique de la semelle supérieure des pièces formant loquet et la hauteur des jambages des cavaliers sont tels qu'un tube ne puisse se dégager didit dispositif d'accrochage sous l'effet d'une force tendant à l'écarter du tube ou de la poutre verticaux, sans que le rebord latéral supérieur d'un cavalier ne vienne en butée contre la face inférieure de l'épaulement correspondant, et la hauteur des jambages d'un cavalier est telle que le jeu entre le rebord latéral dudit cavalier et la face inférieure de l'épaulement soit au plus égal à la moitié de la hauteur de contact du bec de la pièce formant loquet avec le rebord de l'épaulement.
- - La semelle verticale de chaque pièce formant loquet est munie de deux ailes lui permettant d'emboîter les deux côtés de l'épaulement sur lequel ladite pièce formant loquet est accrochée.
- Les cavaliers sont en un matériau consommable à la température de l'enceinte dans laquelle le panneau de tubes est appelé à fontionner.
- - Il comprend au-dessus de l'emplacement occupé par le tube horizontal le plus élevé une pièce de profil inférieur cylindrique concave, de rayon de courbure sensiblement égal à celui du tube horizontal, et soudée sur l'ailette du tube ou de la poutre verticaux de façon à bloquer en position le panneau de tubes horizontaux.
- - The vertical spacing of two shoulders, the width of the cylindrical external part of the upper sole of the parts forming the latch and the height of the legs of the riders are such that a tube cannot be released from this hanging device under the effect with a force tending to move it away from the vertical tube or beam, without the upper lateral edge of a rider abutting against the underside of the corresponding shoulder, and the height of the legs of a rider is such that the clearance between the lateral edge of said rider and the underside of the shoulder is at most equal to half the contact height of the spout of the latch-forming part with the edge of the shoulder.
- - The vertical sole of each piece forming a latch is provided with two wings allowing it to fit the two sides of the shoulder on which said piece forming a latch is hung.
- The jumpers are made of a consumable material at the temperature of the enclosure in which the tube panel is called to operate.
- - It comprises above the location occupied by the highest horizontal tube a part of concave cylindrical lower profile, with a radius of curvature substantially equal to that of the horizontal tube, and welded to the fin of the tube or of the beam vertical so as to lock the horizontal tube panel in position.
Il est décrit ci-après, à titre d'exemple et en référence aux figures du dessin annexé, un dispositif d'accrochage d'un panneau de tubes d'échangeur de chaleur horizontaux sur un tube-support vertical.It is described below, by way of example and with reference to the figures of the appended drawing, a device for attaching a panel of horizontal heat exchanger tubes to a vertical support tube.
La figure 1 représente en vue de profil quelques tubes horizontaux d'un panneau fixés sur des épaulements des ailettes d'un tube vertical, et une pièce formant loquet et un cavalier séparés du dispositif.Figure 1 shows in profile some horizontal tubes of a panel fixed on the shoulders of the fins of a vertical tube, and a part forming a latch and a jumper separated from the device.
La figure 2 représente en perspective éclatée deux supports de tubes, avec des pièces formant loquet et des cavaliers, correspondant à la partie supérieure du dispositif de la figure 1.FIG. 2 shows in exploded perspective two tube supports, with parts forming a latch and jumpers, corresponding to the upper part of the device of FIG. 1.
La figure 3 représente en vue de profil quelques tubes, dont deux couples d'écartement supérieur à celui des autres, correspondant à des parties différentes du panneau, et les pièces formant loquet correspondantes.FIG. 3 represents in profile view a few tubes, including two pairs of spacing greater than that of the others, corresponding to different parts of the panel, and the parts forming the corresponding latch.
Dans les figures 1 et -2, le tube vertical 1 comporte des ailettes verticales soudées opposées 2. Sur ces ailettes sont découpées par poinçonnage des échancrures telles que 3, séparant des épaulements 4 à rebord 5 en saillie vers le haut.In FIGS. 1 and -2, the
La pièce formant loquet 6 comporte une face supérieure 7 sensiblement plane du côté tourné vers le tube porteur vertical, et se relevant de l'autre côté selon un cylindre de rayon de courbure égal à celui d'un tube horizontal tel que 8, de façon à supposer à un décrochement du tube horizontal vers l'extérieur. La largeur de la face supérieure 7 est déterminée en conjonction avec la profondeur des échancrures 3 de façon que les tubes mis en place viennent au contact du fond des échancrures. Au-dessous du côté plan de la face supérieure, la pièce formant loquet est munie d'un bec 9 séparé de la partie médiane par un creux 10 de largeur correspondant à celle du rebord 5 d'un épaulement 4, de façon à s'adapter exactement sur celui-ci. Elle comporte aussi une semelle verticale 11 destinée à s'appliquer contre le rebord de l'épaulement 4, percée dans sa partie inférieure d'un trou rectangulaire 12, et comportant de chaque côté de ce trou des ailes 13 destinées à venir s'appliquer sur les deux faces des épaulements 4. Ces trous 12 sont destinés à permettre l'introduction de cavaliers 14, qui une fois mis en position viennent reposer par leurs jambages sur le pourtour supérieur du tube horizontal immédiatement inférieur. Un rebord latéral supérieur 15 de ces cavaliers est suffisamment prononcé pour venir en butée sur la partie inférieure 16 de l'épaulement correspondant, et pour bloquer ainsi le tube correspondant en cas de sollicitation vers le haut qui tendrait à le décrocher au cours de la mise en place.The
Deux pièces telles que 17, à profil cylindrique concave dans leur partie inférieure, permettent de bloquer en place, après soudage en quelques points tels que 18 sur la partie correspondante d'une ailette du tube vertical, les tubes horizontaux les plus élevés d'un panneau, et par suite l'ensemble des tubes du panneau. Une fois la mise en place des tubes d'un panneau terminée, et les pièces 17 soudées sur les ailettes du tube vertical 1, les cavaliers 14 ne sont plus nécessaires au maintien en place des tubes du panneau. Ils peuvent être constitués en un matériau combustible à la température des gaz de combustion venant au contact du panneau de tubes, et par exemple en matière plastique.Two parts such as 17, with a concave cylindrical profile in their lower part, make it possible to lock in place, after welding at a few points such as 18 on the corresponding part of a fin of the vertical tube, the highest horizontal tubes of a panel, and therefore all of the panel tubes. Once the establishment of the tubes of a panel is complete, and the
La figure 3 représente un dispositif d'accrochage de tubes analogues à celui des figures 1 et 2, mais dans une zone où deux tubes adjacents présentent un écartement supérieur à celui des autres tubes, correspondant par exemple à la limite entre deux parties différentes du panneau de tubes. Les pièces formant loquet 6 sont remplacées à cette heuteur par des pièces 6 A, comportant des semelles verticales 11A plus longues, s'appliquant contre le rebord d'épaulement 3A. Des cavaliers 14, identiques aux autres, sont engagés dans les trous 12, identiques à ceux des autres pièces formant loquet, des pièces 6A.FIG. 3 represents a device for hooking tubes similar to that of FIGS. 1 and 2, but in an area where two adjacent tubes have a spacing greater than that of the other tubes, corresponding for example to the limit between two different parts of the panel of tubes. The parts forming a
L'invention s'applique à l'accrochage de tout panneau de tubes d'échangeur des chaleur horizontaux ou légèrement inclinés, droits ou en hélice à faible pas.The invention applies to the attachment of any panel of horizontal or slightly inclined, straight or helical heat exchanger tubes at low pitch.
