The holding arrangement comprises transverse retaining sections (4) located between each row and longitudinal retaining legs fixed to the sections and encastre in a corresponding fin pitch. Flat bars (6) perpendicular to the transverse retaining sections are fixed by their ends to the support sections separating adjacent tubes. The transverse retaining sections are threaded in n - 1 holes in the bars. The bars and the sections form a holding mesh. The longitudinal retaining legs are constituted by separated U shaped plates (8). The web plate of each plate constitutes an encastre leg and the U branches form tongues connecting to the mesh.

Description

La présente invention se rapporte à un agencement de maintien d'un faisceau de tubes en particulier destiné à former un échangeur de chaleur.The present invention relates to an arrangement for holding a bundle of tubes in particular intended to form a heat exchanger.

Elle concerne plus précisément un agencement de maintien d'un faisceau de tubes constitué de tubes pourvus chacun d'une ailette externe hélicoïdale et disposés en n rangées de p tubes délimitées par des profilés de support, l'agencement comprenant des profilés de maintien transversal disposés entre chaque rangée et des pattes de maintien longitudinal solidaires de ces profilés et encastrées dans un pas du filet de l'ailette du tube correspondant.More specifically, it relates to an arrangement for holding a bundle of tubes made up of tubes each provided with a helical external fin and arranged in n rows of p tubes delimited by support profiles, the arrangement comprising transverse support profiles arranged between each row and longitudinal retaining tabs integral with these profiles and embedded in a pitch of the thread of the fin of the corresponding tube.

De tels agencements connus comportent entre chaque rangée de tubes un certain nombre de profilés de maintien transversal de section carré de côté h sur lesquels sont soudés

  • sur une face, des profilés perpendiculaires de longueur sensiblement égal à la somme du diamètre des tubes et du côté h et espacés les uns des autres d'une distance sensiblement égale au diamètre des tubes,
  • sur la face opposée, les pattes de maintien disposées entre deux profilés précédents et espacées d'une distance choisie selon la résistance de maintien longitudinal nécessaire.
Such known arrangements comprise, between each row of tubes, a certain number of transverse holding profiles of square section with side h on which are welded.
  • on one side, perpendicular sections of length substantially equal to the sum of the diameter of the tubes and of the side h and spaced from each other by a distance substantially equal to the diameter of the tubes,
  • on the opposite face, the holding tabs arranged between two previous sections and spaced by a distance chosen according to the required longitudinal holding resistance.

Répartis sur la longueur du faisceau, sont disposés plusieurs profilés de maintien transversal ainsi constitués. Les tubes sont logés entre les profilés perpendiculaires. Un autre série de profilés de maintien transversal est disposé sur les tubes, leurs pattes étant encastrés dans un pas des ailettes des tubes. Les profilés perpendiculaires des premiers profilés de maintien transversal sont alors soudés aux seconds profilés de maintien transversal. La première rangée est alors fixée et les rangées suivantes sont maintenues de la même façon par mise en place et soudure de profilés analogues.Distributed over the length of the beam, there are several transverse retaining profiles thus formed. The tubes are housed between the perpendicular profiles. Another series of transverse holding profiles is arranged on the tubes, their tabs being embedded in a pitch of the fins of the tubes. The perpendicular sections of the first transverse holding sections are then welded to the second transverse holding sections. The first row is then fixed and the following rows are maintained in the same way by fitting and welding similar profiles.

Un tel faisceau de tubes compose en général un échangeur de chaleur destiné à être parcouru par un fluide caloporteur et est destiné à être mis en place, verticalement ou horizontalement, dans une chaudière de récupération de chaleur, par exemple en sortie de turbine à gaz.Such a bundle of tubes generally makes up a heat exchanger intended to be traversed by a heat transfer fluid and is intended to be installed, vertically or horizontally, in a heat recovery boiler, for example at the outlet of a gas turbine.

La liaison par encastrement sur les tubes des pattes de maintien longitudinal permet au maillage de maintien ainsi réalisé de suivre les déplacements de dilatation longitudinal des tubes.The connection by embedding on the tubes of the longitudinal retaining lugs allows the retaining mesh thus produced to follow the longitudinal expansion displacements of the tubes.

Un tel agencement de maintien connu nécessite:

  • la préfabrication de profilés de maintien transversal pourvus de leurs profilés perpendiculaires et de leurs pattes de maintien, avec des tolérances acceptables de distances entre ces différents éléments,
  • la mise en place simultanée avec chaque profilé de maintien transversal d'un certain nombre de pattes monobloc par encastrement dans le filet des ailettes,
  • la soudure de chaque profilé perpendiculaire d'une première série de profilés de maintien transversal sur une seconde série de profilés de maintien transversal.
Such a known holding arrangement requires:
  • the prefabrication of transverse retaining sections provided with their perpendicular sections and their retaining tabs, with acceptable tolerances of distances between these different elements,
  • the simultaneous installation with each transverse retaining profile of a certain number of one-piece lugs by embedding in the net of the fins,
  • the welding of each perpendicular profile from a first series of transverse support profiles to a second series of transverse support profiles.

L'invention supprime toutes ces opérations, aucune préfabrication ou soudure équivalentes n'étant nécessaire, tout en facilitant la mise en place des différents éléments de l'agencement de maintien. Ceci permet d'obtenir un agencement moins coûteux, en moyens et en main d'oeuvre.The invention eliminates all these operations, no prefabrication or equivalent welding being necessary, while facilitating the installation of the various elements of the holding arrangement. This makes it possible to obtain a less costly arrangement, in terms of resources and manpower.

Pour ce faire, conformément à l'invention,

  • des barres perpendiculaires auxdits profilés de maintien transversal et solidaires par leurs extrémités aux profilés de support séparent les p tubes adjacents des n rangées, les profilés de maintien transversal étant enfilés dans n-1 orifices prévus sur ces barres, lesdites barres et lesdits profilés formant un maillage de maintien,
  • les pattes de maintien longitudinal sont constituées de plats séparés comportant chacun une patte d'encastrement et au moins une languette de liaison avec ledit maillage.
To do this, according to the invention,
  • bars perpendicular to said transverse retaining profiles and integral at their ends with the support profiles separate the p adjacent tubes from the n rows, the transverse retaining profiles being threaded in n-1 holes provided on these bars, said bars and said profiles forming a support mesh,
  • the longitudinal retaining tabs consist of separate plates each comprising a mounting tab and at least one tongue for connection with said mesh.

Ces plats séparés peuvent être mis en place beaucoup plus facilement que les pattes monobloc de l'art antérieur compte tenu du caractère aléatoire de la position des ailettes des tubes et de la nécessité d'une éventuelle déformation pour l'encastrement dans un pas du filet des ces ailettes.These separate dishes can be set up much more easily than the one-piece legs of the prior art, given the random nature of the position of the fins of the tubes and the need for possible deformation for fitting into a thread pitch. of these fins.

Selon le mode de réalisation préféré, la languette de liaison est fixée sur le profilé de maintien transversal correspondant, cette fixation étant réalisée par déformation de cette languette autour du profilé.According to the preferred embodiment, the connecting tongue is fixed to the corresponding transverse holding profile, this fixing being produced by deformation of this tongue around the profile.

Avantageusement, lesdites barres sont constituées de barres plates.Advantageously, said bars consist of flat bars.

De préférence, lesdits plats ont une forme de U, l'âme du U constituant la patte d'encastrement et les branches du U formant deux languettes de liaison.Preferably, said dishes have a U shape, the core of the U constituting the mounting tab and the branches of the U forming two connecting tabs.

L'invention concerne également un échangeur de chaleur constitué d'un faisceau constitué de tubes disposés en n rangées de p tubes, plusieurs agencements de maintien tels que précédemment décrits maintenant ce faisceau, répartis sur la longueur de celui-ci.The invention also relates to a heat exchanger consisting of a bundle consisting of tubes arranged in n rows of p tubes, several holding arrangements as previously described now this bundle, distributed over the length thereof.
