- each leg of this second U-shaped profile 6 is bent inwards in the shape of a Z, as a result of which a groove 8 is formed with a stop 9, which extends in a slope towards the end of the aforementioned leg.
- a groove 8 is formed with a stop 9, which extends in a slope towards the end of the aforementioned leg.
- the depth of each groove 8 is equal to the thickness of the legs of the first U-shaped section 3, so that the outer surfaces of the legs of the two U-shaped sections 3 and 6 are in the same plane.

Description
L'invention concerne un radiateur pour chauffage central selon le préambule de la revendication 1.The invention relates to a central heating radiator according to the preamble of
Un tel radiateur est connu selon le FR-A-2 475 708, dans lequel il est décrit un échangeur de chaleur comprenant des tubes plats disposés parallèlement entre eux et raccordés à des collecteurs d'entrée et de sortie, où pour le raccordement des tubes plats aux collecteurs, ces derniers comportent des trous entourés par une zone de paroi qui est emboutie vers l'extérieur, afin de pouvoir souder un côté plat des tubes aux collecteurs. Les extrémités ouvertes de chaque tube sont rabattues vers l'intérieur et fermées par un joint soudé. Cet échangeur a donc l'inconvénient que plusieurs opérations sont nécessaires pour son assemblage et qu'il est très difficile de positionner les tubes plats par rapport aux trous.Such a radiator is known according to FR-A-2 475 708, in which there is described a heat exchanger comprising flat tubes arranged parallel to each other and connected to inlet and outlet manifolds, where for the connection of the tubes flat to the collectors, the latter have holes surrounded by a wall area which is stamped outwards, in order to be able to weld a flat side of the tubes to the collectors. The open ends of each tube are folded inwards and closed with a welded joint. This exchanger therefore has the disadvantage that several operations are necessary for its assembly and that it is very difficult to position the flat tubes relative to the holes.
Du GB-A-2 082 312 on connaît également un radiateur où les extrémités des tuyaux parallèles sont montées dans des trous préalablement poinçonnés dans une bande métallique en U et sont brasés à cette bande. Pour la formation d'un collecteur aux deux extrémités des tuyaux, un profilé en U est placé dans chaque bande métallique en U et le profilé est soudé par une soudure d'angle à l'extérieur sur la bande métallique.From GB-A-2 082 312 there is also known a radiator where the ends of the parallel pipes are mounted in holes previously punched in a U-shaped metal strip and are brazed to this strip. For the formation of a manifold at both ends of the pipes, a U-shaped profile is placed in each U-shaped metal strip and the profile is welded by an outside corner weld on the metal strip.
Un important inconvénient de ce radiateur est que les soudures d'angles visibles sont vilainement achevées et que les soudures d'angle ne peuvent être égalisées rapidement et automatiquement et rendues proprement lisses qu'avec peine. Un autre inconvénient est qu'ainsi la réalisation de soudures d'angle au moyen d'un dispositif automatique est difficile à exécuter.An important drawback of this radiator is that the visible corner welds are badly finished and that the corner welds can only be smoothed quickly and automatically and made properly smooth only with difficulty. Another disadvantage is that thus making corner welds by means of an automatic device is difficult to perform.
Pour remédier à tous ces inconvénients, on a réalisé selon l'invention un radiateur dont les caractéristiques sont définies dans la revendication 1.To remedy all these drawbacks, a radiator has been produced according to the invention, the characteristics of which are defined in
Ce radiateur n'a pas seulement l'avantage que les soudures par lesquelles les tuyaux parallèles sont soudées au côté intérieur des collecteurs sont soustraites à la vue et ne nécessitent pas d'autre façonnage, mais qu'en même temps les deux profilés en U des collecteurs sont soudés l'un à l'autre par une soudure plate qui peut être facilement égalisée et rendue lisse. Un autre avantage est que le montage du radiateur est très simple et demande peu d'opérations.This radiator has not only the advantage that the welds by which the parallel pipes are welded to the inner side of the collectors are hidden from view and do not require further shaping, but that at the same time the two U-shaped profiles collectors are welded to each other by a flat weld which can be easily leveled and made smooth. Another advantage is that the mounting of the radiator is very simple and requires few operations.
A titre d'exemple suit ci-après une description détaillée d'une forme choisie mais nullement limitée du radiateur conforme à l'invention. Cette description renvoie au dessin ci-annexé, dans lequel :
- la fig. 1 représente une coupe horizontale d'une extrémité du radiateur;
- la fig. 2 représente une coupe verticale suivant la ligne II-II de la fig. 1.
- fig. 1 shows a horizontal section of one end of the radiator;
- fig. 2 shows a vertical section along line II-II of FIG. 1.
Dans ces figures, on remarque que chaque extrémité des tuyaux parallèles 1 du radiateur s'ajuste dans un des trous 2 qui sont aménagés l'un en dessous de l'autre dans un premier profilé en U 3 fermé en haut et en bas et faisant partie d'un collecteur 4 à former le long des deux extrémités des tuyaux. Le long du côté intérieur du profilé en U 3 de chaque collecteur 4, les extrémités des tuyaux 1 sont soudées au moyen d'une soudure 5 au profilé en U 3, de sorte que la soudure est soustraite à la vue et qu'aucun autre façonnage n'est nécessaire. Pour fermer ensuite chaque collecteur 4, il est fait usage d'un deuxième profilé en U 6 fermé en haut et en bas et pourvu de manchons 7 à filetage dont un seul est visible dans le dessin et qui servent au raccordement des conduites d'amenée et d'évacuation de l'installation de chauffage central. L'extrémité de chaque jambe de ce deuxième profilé en U 6 est pliée vers l'intérieur en forme de Z, par suite de quoi une rainure 8 est formée avec une butée 9, qui s'étend en pente vers l'extrémité de la jambe précitée. Par-dessus chaque extrémité et dans la rainure 8 de chaque jambe, l'extrémité d'une des jambes du premier profilé en U 3 est poussée. La profondeur de chaque rainure 8 est égale à l'épaisseur des jambes du premier profilé en U 3, de sorte que les surfaces extérieures des jambes des deux profilés en U 3 et 6 se trouvent dans un même plan. Grâce à la butée 9 en pente de chaque rainure 8, il reste un espace ouvert entre la butée 9 et la jambe du premier profilé en U 3 s'introduisant dans la rainure 8, lequel espace ouvert est ensuite soudé au moyen d'une soudure plate 10 sur toute la longueur du collecteur. La soudure plate peut ensuite être aplanie sans problèmes d'une manière simple au moyen d'un dispositif automatique.In these figures, we note that each end of the
