Description

Coffret etanche faisant partie d'une installation de conditionnement d'air
La présente invention concerne un coffret étanche faisant partie d'une installation de conditionnement d'air.
Waterproof enclosure as part of an air conditioning installation
The present invention relates to a sealed enclosure forming part of an air conditioning installation.

On connais des coffrets-de ce genre par exemple par la demande de brevet français nO 24 90 325. We know of boxes of this kind for example by French patent application No. 24 90 325.

De tels coffrets assemblés les uns aux autres contiennent chacun un ou plusieurs éléments de traitement d'air tel que filtres, ventilateurs, échangeurs de chaleur, clapets permettant de diriger le flux -d'air vers tel ou tel circuit etc,.. Un tel coffret doit évidemment être étanche et isolé thermiquement, cependant, afin de pouvoir visiter, pour les entretenir ou les changer, les éléments qui s'y trouvent, il doit pouvoir s'ouvrir
L'étanchéité à l'air sur le pourtour de l'ouverture est ainsi délicate.
Such boxes assembled to each other each contain one or more air treatment elements such as filters, fans, heat exchangers, valves making it possible to direct the flow of air to such and such a circuit, etc. box must obviously be waterproof and thermally insulated, however, in order to be able to visit, to maintain or change them, the elements which are there, it must be able to open
Air tightness around the opening is thus delicate.

L'invention a pour but de proposer un coffret qui est parfaitement adéquat du point de vue de son étanchéité à l'endroit de l'ouverture tout en étant simple et économique. The invention aims to provide a box which is perfectly adequate from the point of view of its tightness at the location of the opening while being simple and economical.

L'invention a ainsi pour objet un coffret étanche faisant partie d'une installation de conditionnement d'air et contenant un ou plusieurs éléments de traitement de l'air, ledit coffret comprenant un couvercle de fermeture à rebords de recouvrement et au moins un orifice dPentrée et un orifice de sortie et comportant une isolation thermique sur toutes ses parois internes, caractérisé en ce que le pourtour interne supérieur des parois du coffret est muni de profiles comportant une aile écartée des parois du coffret, réalisant un canal à la partie supérieure du coffret, ledit canal étant muni d'un joint souple dépassant, en l'absence du couvercle, le bord supérieur du coffret et étant écrasé par le couvercle dans sa position fermée. The subject of the invention is therefore a sealed box forming part of an air conditioning installation and containing one or more air treatment elements, said box comprising a closure cover with overlapping edges and at least one orifice. d Entrance and an outlet orifice and having thermal insulation on all its internal walls, characterized in that the upper internal periphery of the walls of the cabinet is provided with profiles comprising a wing spaced from the walls of the cabinet, providing a channel at the top of the cabinet, said channel being provided with a flexible seal projecting, in the absence of the cover, the upper edge of the cabinet and being crushed by the cover in its closed position.

Selon une autre caractéristique de l'invention, lesdits profilés sont constitués par des bandes métalliques d'une épaisseur propre à leur conférer une certaine souplesse, lesdites bandes étant pliées en forme de k) ou de 0 et fixees par une de leurs ailes verticales aux parois du coffret. According to another characteristic of the invention, said sections consist of metal strips of a thickness suitable for giving them a certain flexibility, said strips being folded in the form of k) or 0 and fixed by one of their vertical wings to the cabinet walls.

L'invention sera bien comprise à la lumière de la description d'un exemple de réalisation de l'invention, faite ci-après en regard du dessin annexé dans lequel
La figure 1 montre en perspective avec une partie arrachée, un coffret selon l'invention.
The invention will be clearly understood in the light of the description of an embodiment of the invention, given below with reference to the appended drawing in which
Figure 1 shows in perspective with a cutaway part, a box according to the invention.

La figure 2 montre en perspective, et en position fermé du couvercle, le detail A de la figure 1. FIG. 2 shows in perspective, and in the closed position of the cover, the detail A of FIG. 1.

La figure 3 montre le détail A de la figure 1 dans une position où le couvercle n'est pas complètement fermé. Figure 3 shows the detail A of Figure 1 in a position where the cover is not completely closed.

La figure 4 montre le coffret en vue de dessus sans son couvercle. Figure 4 shows the cabinet in top view without its cover.

Le coffret est constitué d'une boite parallélépipédique 1 métallique comportant un couvercle 2 à rebords recouvrants 3. il comprend une ouverture 4 destinée à être raccordée à une conduite 5 ou à un autre coffret. The box consists of a metal parallelepiped box 1 having a cover 2 with overlapping edges 3. it includes an opening 4 intended to be connected to a pipe 5 or to another box.

On a figuré en pointillé 20 sur la face avant, le contour d'une autre ouverture. Un simple choc à l'intérieur du contour permet d'ôter la partie entourée. Au moins deux ouvertures doivent être pratiquées : l'une servant d'entrée d'air et l'autre de sortie. There has been a dotted line 20 on the front face, the outline of another opening. A simple shock inside the contour removes the surrounded part. At least two openings must be made: one serving as an air inlet and the other as an outlet.

Les parois internes du coffret sont munies d'un isolant thermique 6 par exemple en fibres ou en laine minérale, de même que le dessous du couvercle 2. The internal walls of the box are provided with a thermal insulator 6, for example made of fibers or mineral wool, as is the underside of the cover 2.

La partie supérieure interne des parois latérales 7 du coffret 1 est munie de profilés métalliques 8 comportant chacun deux ailes verticales 9 et 10 réunies par une partie horizontale 11. Un profilé est constitué par une bande métallique pliée en 0 ou en P , comme sur les figures. L'épaisseur d'un profilé est telle qu'il conserve une certaine souplesse de telle sorte que l'aile 9 du profilé, écarté de la paroi 7 peut, sous une certaine pression, s'écarter de la position verticale, comme on le voit sur la figure 2. Ces profilés sont fixés, par leur autre aile verticale 10, à la paroi 7 du coffret 1. Ces profilés réalisent un canal à la partie supérieure du coffret qui reçoit un joint souple 12, remplissant entièrement la section du canal et dépassant le bord supérieur des parois 7 du coffret, comme le montre clairement la figure 3. The internal upper part of the side walls 7 of the box 1 is provided with metal profiles 8 each comprising two vertical wings 9 and 10 joined by a horizontal part 11. A profile is constituted by a metal strip folded in 0 or in P, as in the figures. The thickness of a profile is such that it retains a certain flexibility so that the wing 9 of the profile, spaced from the wall 7 can, under a certain pressure, deviate from the vertical position, as is see in Figure 2. These profiles are fixed, by their other vertical wing 10, to the wall 7 of the cabinet 1. These profiles provide a channel at the top of the cabinet which receives a flexible seal 12, completely filling the section of the channel and extending beyond the upper edge of the walls 7 of the box, as clearly shown in FIG. 3.

Lorsque l'on ferme le couvercle 2, comme le montre la figure 2, le joint souple 12 est écrasé et exerce un effort contre l'aile 9 de chaque profilé 8 qui prend une position oblique. La figure 4 montre la dispo sition relative des profilés (aile 9) sur les quatre parois 7 du coffret 1, chaque profilé étant un peu plus court que le côté de chaque paroi. En position fermée du couvercle, l'aile 9 de chaque profilé vient s'appuyer à l'une de ses extrémités contre le bout de aile 9 du profilé du côté voisin. Cette disposition assure une excellente étanchéité même dans les coins. Le joint 12 peut par exemple être réalisé en une mousse synthétique. When the cover 2 is closed, as shown in FIG. 2, the flexible seal 12 is crushed and exerts a force against the wing 9 of each profile 8 which takes an oblique position. Figure 4 shows the relative availability of the profiles (wing 9) on the four walls 7 of the box 1, each profile being a little shorter than the side of each wall. In the closed position of the cover, the wing 9 of each section bears at one of its ends against the end of wing 9 of the section on the neighboring side. This arrangement ensures an excellent seal even in the corners. The seal 12 can for example be made of a synthetic foam.

Comme on le voit sur la figure 2, le joint souple d'étanchéité 12 est entièrement protégé et isolé de la température qui règne à lssinté- rieur du caisson par l'isolant thermique 6, protégeant ainsi ce joint contre un vieillissement prématuré du à la chaleur.  As seen in Figure 2, the flexible seal 12 is fully protected and isolated from the temperature prevailing inside the box by the thermal insulation 6, thereby protecting this seal against premature aging due to the heat.
