The convective element consists of a fluted sheet with its corrugations parallel to each other. The corrugations (31) of the convective element (3) extend in a direction which is transverse with respect to the ribs (13) of the shell (11) to which the convective element is fixed. <IMAGE>

Description

La présente invention concerne un panneau de radiateur à convection en acier équipé d'ailettes de convection.The present invention relates to a steel convection radiator panel fitted with convection fins.

Un panneau de radiateur de chaleur à convection en acier est usuellement constitué de deux plaques ou coquilles en acier soudées entre elles et présentant des nervures qui délimitent des canaux d'eau ou de fluide débouchant dans des collecteurs. Pour améliorer la convection de chaleur, on a déjà proposé de fixer un élément de convection formant ailettes sur une face de rayonnement du panneau. Un tel élément de convection est constitué d'une tôle profilée pour former des ondulations qui s'étendent suivant la direction des nervures formant les canaux de fluide. Dans ce mode de réalisation, le pas des ondulations de l'élément de convection est et doit être lié au pas des nervures des plaques de rayonnement. L'efficacité de la convection thermique se trouve ainsi liée au type de plaque utilisé, ce qui limite les possibi­lités d'assemblage et de montage.A steel convection heat radiator panel usually consists of two steel plates or shells welded together and having ribs which delimit channels of water or fluid opening into collectors. To improve convection of heat, it has already been proposed to fix a convection element forming fins on a radiation face of the panel. Such a convection element consists of a profiled sheet to form corrugations which extend in the direction of the ribs forming the fluid channels. In this embodiment, the pitch of the undulations of the convection element is and must be linked to the pitch of the ribs of the radiating plates. The efficiency of thermal convection is thus linked to the type of plate used, which limits the possibilities of assembly and mounting.

L'invention a pour objet un panneau de radiateur en acier qui permet une fabrication plus rationnelle et plus uniforme des plaques et qui permet une grande souplesse d'assemblage et de montage.The subject of the invention is a steel radiator panel which allows a more rational and uniform production of the plates and which allows great flexibility of assembly and mounting.

Cet objectif est atteint grâce à un panneau de radiateur à convection qui se caractérise par un élément de convection ayant des ondulations s'étendant suivant une direction transversale à la direction des nervures de la coquille sur laquelle cet élément est fixé.This objective is achieved thanks to a convection radiator panel which is characterized by an element convection having corrugations extending in a direction transverse to the direction of the ribs of the shell on which this element is fixed.

Le panneau de radiateur selon l'invention présente plusieurs avantages très appréciables :

  • 1. le pas de l'élément de convection est rendu indépendant du pas des nervures des coquilles, ce qui permet de disposer un nombre plus ou moins grand d'ondulations de l'élément de convection pour un même panneau et par conséquent d'étendre et optimiser la surface de chauffe par convection, pour une même surface de plaque ;
  • 2. la rigidité du panneau se trouve augmentée grâce à un accroissement moment d'inertie dans l'axe des points de soudure de l'élément de convection sur la coquille par suite de la liaison entre eux de deux profils à ondulations croisées;
  • 3. la circulation de fluide est améliorée dans le cas de panneaux à canaux de fluide croisés;
  • 4. les deux faces d'un panneau peuvent être utilisées indifféremment comme face extérieure visible ou comme face arrière sur laquelle est fixé l'élément de convection;
  • 5. la face extérieure visible d'un panneau peut être réalisée avec un libre choix de l'aspect esthétique puisque la réalisation de la plaque visible est rendue indépendante de l'efficacité thermique de convection.
The radiator panel according to the invention has several very appreciable advantages:
  • 1. the pitch of the convection element is made independent of the pitch of the ribs of the shells, which makes it possible to have a greater or lesser number of undulations of the convection element for the same panel and consequently to extend and optimize the heating surface by convection, for the same plate surface;
  • 2. the rigidity of the panel is increased thanks to an increase in the moment of inertia in the axis of the welding points of the convection element on the shell as a result of the connection between them of two profiles with crossed undulations;
  • 3. the circulation of fluid is improved in the case of panels with crossed fluid channels;
  • 4. the two sides of a panel can be used either as a visible external face or as a rear face on which the convection element is fixed;
  • 5. the visible external face of a panel can be produced with a free choice of aesthetic appearance since the production of the visible plate is made independent of the thermal efficiency of convection.

L'invention est exposée dans ce qui suit à l'aide des dessins ci-annexés dans lesquels :

  • - la figure 1 est une vue en perspective partielle d'un corps de chauffe exemplaire comportant deux panneaux selon l'invention,
  • - la figure 2 est une vue en perspective partielle d'un panneau du corps de chauffe de la figure 1,
  • - la figure 3 est une coupe suivant la ligne III-III de la figure 2,
  • - la figure 4 est une coupe suivant la ligne IV-IV de la figure 2,
  • - la figure 5 est une coupe suivant la ligne V-V de la figure 2,
  • - la figure 6 est une coupe suivant la ligne VI-VI de la figure 2,
  • - les figures 7A et 7B montrent deux manières de monter un panneau de radiateur selon l'invention.
The invention is set out in the following with the aid of the appended drawings in which:
  • FIG. 1 is a partial perspective view of an exemplary heating body comprising two panels according to the invention,
  • FIG. 2 is a partial perspective view of a panel of the heater body of FIG. 1,
  • FIG. 3 is a section along the line III-III in FIG. 2,
  • FIG. 4 is a section along line IV-IV of FIG. 2,
  • FIG. 5 is a section along the line VV in FIG. 2,
  • FIG. 6 is a section along line VI-VI of FIG. 2,
  • - Figures 7A and 7B show two ways of mounting a radiator panel according to the invention.

Se reportant à la figure 1 on voit une partie d'un corps de chauffe exemplaire comprenant deux panneaux 1 et 2 reliés à leurs coins par des raccords, dont un raccord est montré en 4. Ces raccords sont en communication avec des collecteurs supérieurs et inférieurs qui s'étendent le long des bords horizontaux des panneaux. Seul le collec­teur supérieur est identifié dans les dessins : il est repéré en 5. Sur les faces intérieures des panneaux sont soudés des éléments de convection 3.Referring to Figure 1 we see a part of an exemplary heater comprising two panels 1 and 2 connected at their corners by fittings, one of which is shown in 4. These fittings are in communication with upper and lower manifolds which extend along the horizontal edges of the panels. Only the upper collector is identified in the drawings: it is identified at 5. On the inside faces of the panels are welded convection elements 3.

Chaque panneau est constitué de deux plaques ou coquilles en acier soudées l'une à l'autre et présentant des nervures de manière à former un réseau de canaux d'eau ou de fluide qui communiquent avec les collecteurs. Dans le mode d'exécution exemplaire illustré dans les dessins, les plaques intérieures 11 des panneaux présentent des nervures horizontales 13 et les plaques extérieures 12 présentent des nervures verticales 14. Ces nervures ainsi que les canaux de fluide 15 et 16 sont bien visibles dans les figures 2 à 6.Each panel consists of two steel plates or shells welded to each other and having ribs so as to form a network of water or fluid channels which communicate with the collectors. In the exemplary embodiment illustrated in the drawings, the inner plates 11 of the panels have horizontal ribs 13 and the outer plates 12 have vertical ribs 14. These ribs as well as the fluid channels 15 and 16 are clearly visible in the Figures 2 to 6.

La disposition caractéristique d'un élément de convection selon l'invention apparaît clairement dans la figure 2 qui montre une partie du panneau 1 vu du côté de sa face intérieure formée par la coquille 11. L'élément de convection 3 est constitué d'une tôle présentant des ondulations 31 qui s'étendent transversalement à la direction des nervures 13 de la coquille 11 sur laquelle elle est fixée. Grâce au fait que les ondulations 31 de l'élément de convection 3 sont transversales à la direction des nervures de la coquille 11, le pas des ondulations de l'élément de convection est rendu indépendant du pas des nervures de la coquille. L'élément de convection peut dès lors comporter un nombre quelconque d'ondulations pour une même plaque de radiateur, c'est-à-dire un nombre quel­conque d'ailettes de convection pour une même longueur de plaque. Il est ainsi possible, grâce à l'invention, d'optimiser l'efficacité de convection thermique en réali­sant le rapport optimum de la hauteur h de l'élément de convection à la largeur p de l'ailette de convection pour une profondeur e donnée de l'ondulation.The characteristic arrangement of a convection element according to the invention appears clearly in FIG. 2 which shows part of the panel 1 seen from the side of its inner face formed by the shell 11. The convection element 3 consists of a sheet metal having corrugations 31 which extend transversely to the direction of the ribs 13 of the shell 11 on which it is fixed. Thanks to the fact that the corrugations 31 of the convection element 3 are transverse to the direction of the ribs of the shell 11, the pitch of the corrugations of the convection element is made independent of the pitch of the ribs of the shell. The convection element can therefore include any number of corrugations for the same radiator plate, that is to say any number of convection fins for the same length of plate. It is thus possible, thanks to the invention, to optimize the efficiency of thermal convection by achieving the optimum ratio of the height h of the convection element to the width p of the convection fin for a given depth e of the ripple.

De plus, le mode de construction selon l'invention assure également au panneau une rigidité améliorée grâce à un accroissement du moment d'inertie dans l'axe des points de soudure de l'élément de convection sur le panneau en raison de la liaison entre eux de deux profils ayant leurs ondulations qui s'étendent suivant des directions croisées.In addition, the method of construction according to the invention also provides the panel with improved rigidity by virtue of an increase in the moment of inertia in the axis of the weld points of the convection element on the panel due to the connection between them of two profiles having their undulations which extend in crossed directions.

On a vue plus haut que les deux faces du panneau de la figure 1 présentent des nervures orientées suivant des directions différentes, respectivement horizontale et verticale, délimitant ainsi un réseau de canaux de fluide croisés 15 et 16 qui sont en communication entre eux et avec les collecteurs supérieur et inférieur. Ce mode de réalisation a pour avantage d'assurer une meilleure répartition de la circulation du fluide thermique dans le panneau.We have seen above that the two faces of the panel in FIG. 1 have ribs oriented in different directions, respectively horizontal and vertical, thus delimiting a network of crossed fluid channels 15 and 16 which are in communication with each other and with the upper and lower manifolds. This embodiment has the advantage of ensuring a better distribution of the circulation of the thermal fluid in the panel.

Un aspect pratique intéressant du mode de construction selon l'invention est illustré par les figures 7A et 7B. Ces figures montrent le même panneau 1 constitué des coquilles 11 et 12 ayant des nervures 13 et 14 qui s'éten­dent suivant des directions croisées. Dans la figure 7A, la coquille 12 est utilisée comme face extérieure du panneau et la coquille 11 est utilisée comme face arrière sur laquelle est fixé l'élément de convection 3 dont les ondulations s'étendent transversalement à la direction longitudinale des nervures de la coquille 11. La figure 7B montre le même panneau 1 avec sa coquille 11 utilisée comme face extérieure et sa coquille 12 utilisée comme face arrière sur laquelle est fixé l'élément de convection 3 disposé conformément à l'invention, et ce tout en conservant au panneau le même aspect esthétique extérieur. Cela permet avantageusement une grande souplesse d'assem­blage et de montage de panneaux réalisés à partir des mêmes coquilles.An interesting practical aspect of the construction method according to the invention is illustrated by FIGS. 7A and 7B. These figures show the same panel 1 consisting of shells 11 and 12 having ribs 13 and 14 which extend in crossed directions. In FIG. 7A, the shell 12 is used as the outer face of the panel and the shell 11 is used as the rear face on which the convection element 3 is fixed, the corrugations of which extend transversely to the longitudinal direction of the ribs of the shell 11. FIG. 7B shows the same panel 1 with its shell 11 used as the external face and its shell 12 used as the rear face on which is fixed the convection element 3 arranged in accordance with the invention, while keeping the panel the same exterior aesthetic appearance. This advantageously allows great flexibility of assembly and mounting of panels made from the same shells.

Il est bien évident que la disposition et la structure des nervures de la coquille formant la face extérieure d'un panneau peuvent être quelconques puisque ces disposition et structure sont indépendantes de la disposition des on­dulations de l'élément de convection comme décrit plus haut. L'efficacité thermique est donc, selon l'invention, tout à fait indépendante de l'aspect esthétique de la face extérieure d'un panneau de chauffe, ce qui permet de réaliser des panneaux de radiateur ayant une face visible qui présente un aspect esthétique différent de l'aspect traditionnel des panneaux de radiateur dans lesquels les faces visibles présentent uniformément des nervures per­pendiculaires à la direction longitudinale des panneaux. De plus, lorsque les panneaux ont une coquille extérieure qui présente des nervures s'étendant suivant la même direction que les nervures de la coquille intérieure, il est possible d'équiper les panneaux d'éléments de convec­tion sur les deux faces.It is obvious that the arrangement and structure of the ribs of the shell forming the outer face of a panel can be arbitrary since these arrangement and structure are independent of the arrangement of the corrugations of the convection element as described above. Thermal efficiency is therefore, according to the invention, entirely independent of the aesthetic appearance of the external face of a heating panel, which makes it possible to producing radiator panels having a visible face which has an aesthetic appearance different from the traditional appearance of radiator panels in which the visible faces uniformly have ribs perpendicular to the longitudinal direction of the panels. In addition, when the panels have an outer shell which has ribs extending in the same direction as the ribs of the inner shell, it is possible to equip the panels with convection elements on both sides.
