Description

       

  La présente invention a pour objet des perfectionnements aux radiateurs en tôle pour chauffage central à l'eau chaude et vise à pourvoir des types de radiateurs très économiques et ayant un rendement très élevé.

  
Les radiateurs suivant l'invention sont formés par des tôles minces embouties et soudées aux bords de manière à laisser à l'intérieur une chambre très étroite, substantiellement continue, munie à un de ses bords verticaux, vers la partie supérieure et inférieure, des pièces en forme de manchon de raccordement au tuyautage de l'installation de chauffage.

  
Le cas échéant, les radiateurs pourront appuyer sur des pieds constitués par des appendices inférieurs des tôles.

  
Suivant une réalisation de l'invention, chaque radiateur est formé de manière que la nappe d'eau comporte, en coupe horizontale, plusieurs branches parallèles.

  
En général, chaque radiateur comporte plusieurs éléments plats verticaux convenablement écartés et formant entre eux des carneaux d'air qui peuvent être munis, à leur partie supérieure, de plaques déflectrices. Ces éléments plats verticaux peuvent être formés en repliant convenablement un couple de tôles embouties et soudées aux bords, en prévoyant à cet effet dans une des tôles des plis en correspondance des parties à plier.

  
En considération du fait que les radiateurs ont leurs parois délimitant la nappe d'eau très rapprochées, à l'intérieur des chambres plates de passage de l'eau de chauffage sont prévus des moyens pour maintenir écartées les parois du radiateur, qui, étant en tôle pince, possè dent une bonne flexibilité.

  
Afin de rendre les parois du radiateur plus raides et maintenir l'écartement entre ses parois dans au moins une des tôles formant

  
le radiateur, sont formées par emboutissage des parties saillantes ou protubérances qui touchent la paroi de la tôle en face.

  The present invention relates to improvements in sheet metal radiators for central heating with hot water and aims to provide types of radiators which are very economical and have a very high efficiency.

  
The radiators according to the invention are formed by thin stamped sheets welded to the edges so as to leave inside a very narrow, substantially continuous chamber, provided at one of its vertical edges, towards the upper and lower part, with parts. in the form of a connection sleeve for the piping of the heating installation.

  
Where appropriate, the radiators may rest on feet formed by lower appendages of the sheets.

  
According to one embodiment of the invention, each radiator is formed so that the sheet of water comprises, in horizontal section, several parallel branches.

  
In general, each radiator comprises several vertical flat elements suitably spaced apart and forming between them air ducts which can be provided, at their upper part, with deflector plates. These vertical flat elements can be formed by suitably folding a pair of stamped sheets and welded to the edges, by providing for this purpose in one of the sheets of the folds corresponding to the parts to be folded.

  
In consideration of the fact that the radiators have their walls delimiting the water table very close together, inside the flat chambers for the passage of the heating water are provided means for keeping the walls of the radiator apart, which, being in gripper sheet, has good flexibility.

  
In order to make the walls of the radiator stiffer and to maintain the spacing between its walls in at least one of the sheets forming

  
the radiator, are formed by stamping the protrusions or protuberances which touch the wall of the facing sheet.

  
Other characteristics and advantages of the invention will emerge from the description which follows, given with reference to the accompanying drawings in which FIG. 1 shows in front elevation a first embodiment of a radiator;

  
Figures 2, 3 and 4 are sections taken along lines II-II, 11II-III and IV-IV of Figure 1; FIG. 5 shows in front elevation a second embodiment of a radiator;

  
FIGS. 6 and 7 are cross sections along VI-VI and VII-VII of FIG. 5, FIG. 8 shows in section the sheets of which the radiator shown in FIGS. 5 to 7 is formed, before their folding in the form of a radiator, the Figures 9 and 10 show respectively in horizontal section and in side elevation two other embodiments of the radiator,

  
Figures 11 and 12 show in perspective two other embodiments of the water table radiator and

trale. so as to leave narrow edges which can be welded together leaving a narrow vertical chamber through which can pass

a sheet of hot water which is supplied by the inlet pipe Ca and

comes out of the outlet duct. Cs These two conduits are inserted in

sleeve-shaped parts M formed by stamping sheets T and T '.

In view of the fact that the sheets of which the radiator is formed are rather thin. in the simplest embodiment of the radiator, they are

kept at a suitable distance by spacers or parts E (figures 1 to 4)

According to the embodiment shown in Figures 5 to 8. one of the

two sheets forming the radiator is provided with protuberances P which, in

the example shown in the drawing, are in the form of truncated pyramids. but who

can be frustoconical. spherical cap, or others. These protuberances, which are formed by stamping one of the sheets, touch

the wall of the sheet in front. and serve as a spacer element which -

also make the sheet where they are formed more rigid.

As can be seen in figures 7. 9, 11 and 12. the radiators

can be formed by bending, for example, into a U-shape, (Figures 7 and

9) or double U '(figure 11) or spiral (figure 12) couples of

of sleeves C for the application of the inlet and outlet ducts of

heating water. The pairs of sheets T and T 'can be. before

their folding, completely parallel and then, during their folding, the

sheet T 'which remains inside the radiator will be bent in correspondence of the elbows, substantially at an angle R (Figures 7 and 9). However, especially when doing multiple folds (Figures 11 and

12) it is advisable to provide on the sheet which remains outside the

teur folded (Figures 11 and 12) is formed by two perfectly parallel sheets.

In many cases, when the structure of the radiator is

sufficiently rigid we can do without spacer elements.

Regarding the C (or Ca-Cs) supply conduits or

outlet of the heating water, in the case of complex radiators, such as

those shown in figures 9 to 12. they can be inserted into the radiators either directly (figures 11 and 12) or else using a tube

distributor K. (figures 9 and 10).

The sheet water radiators according to the invention

are particularly suitable for heating by air convection, forming

H flues between parallel radiator elements. To avoid

that these flues of hot air let go of the walls, staining them by effect

air entrained dust, it can be easily applied to

radiators of the deflector plates D which direct the flow of hot air

towards the interior of the chamber to be heated.

As can be seen from the drawing, the water table radiators

heat according to the invention can be formed with V-legs by simply providing appendages at the lower edges of the

sheet metal.

Of course the tablecloth radiators ?. water according to the invention may undergo many other variant embodiments, all

while remaining within the limits of the invention or the scope of the claims.
