PERFECTIONNEMENTS AUX ELEMENTS RADIANTS, DU TYPE TUYAUX A AILETTES.
La présente.invention concerne des perfectionnements apportés aux éléments radiants du type tuyaux à ailettes consistant à disposer à l'in- térieur du tuyau une tôle mince enroulée en hélice et à faire porter par ce tuyau une série d'ailettes en tôle découpée, équidistantes,; et disposées à écartement convenable, percées d'un trou central autour duquel on a formé par estampage un collier destiné à recevoir le tuyau; ce collier est de diamètre légèrement plus fort sur une courte hauteur au voisinage de l'ailette afin de recevoir par emboîtemen.G le bord-extrême du collier de-l'ailette suivante.
On monte les ailettes en les enfilant à force sur le tuyau l'une après l'autre en engageant l'extrémité du collier de chacune dans la partie élargie du collier de l'ailette précécente de manière à ne plus constituer qu'un seul tuyau.
Il est possible, avec ces perfectionnements, de contraindre le fluide, grâce à la tôle enroulée en hélice, à venir lècher uniformément et plus in censémenttoute la surface interne du tuyau accroissant:., ainsi le rendement des échanges thermiques également accru par la disposition des ai- lettes indiquées plus haut.
Le dessin joint représente à titre d'exemple une forme de réali- sation des perfectionnements conformément à la présente invention, la fig. donne une coupe'radiale partielle d'un élément radiant.
.!.J'élément radiant est constitué par un tuyau I à l'intérieur duquel est logée une tôle mince 2 enroulée en hélice,à l'extérieur sont enfon- cées à force sur le tuyau des ailettes 3 en tôle découpée, équidistantes et disposées à l'écartement convenable, percées d'un trou en leur centre, un col- lier 4 étant obtenu par estampage tout autour de ce trou. Ce collier à un
<Desc/Clms Page number 2>
diamètre légèrement plus fort. au voisinage de l'ailette afin de pouvoir rece- voir par emboîtement le bord du collier de l'ailette suivante.
On obtient ainsi un seul bloc à haut rendement thermique qui peut, également être utilisé avec succès pour les radiateurs d'autos.
RESUMES.
Perfectionnements aux éléments radiants du type tuyaux à ailei'- tes caractérisés en ce que :
1 Le tuyau parcouru par le fluide chaud renferme une tôle mince enroulée en hélice.
2 ) On enfile à force à l'extérieur du tuyau une série d'ailec- des en tôle découpée,, équidistantes et disposées à un écartement convenable les unes par rapport aux autres, ces ailettes étant percées d'un trou en leur centre et un collier étant obtenu par estampage tout autour de ce trou.

IMPROVEMENTS TO THE RADIANT ELEMENTS, OF THE PIPE WITH FINES.
The present invention relates to improvements made to radiant elements of the finned pipe type consisting in placing a thin sheet inside the pipe wound in a helix and in causing this pipe to carry a series of cut-out, equidistant sheet metal fins. ,; and arranged at suitable spacing, pierced with a central hole around which has been formed by stamping a collar intended to receive the pipe; this collar is slightly larger in diameter over a short height in the vicinity of the fin in order to receive by interlocking the extreme edge of the collar of the next fin.
The fins are mounted by threading them by force on the pipe one after the other by engaging the end of the collar of each in the widened part of the collar of the previous fin so as to form only one pipe. .
It is possible, with these improvements, to force the fluid, thanks to the helically wound sheet metal, to come and release uniformly and more censoriously the entire internal surface of the pipe, increasing:. fins indicated above.
The accompanying drawing shows by way of example one embodiment of the improvements in accordance with the present invention, FIG. gives a partial radial section of a radiant element.
.!. The radiant element consists of a pipe I inside which is housed a thin sheet 2 wound in a helix, on the outside are forced into the pipe fins 3 in cut sheet, equidistant and arranged at the appropriate spacing, pierced with a hole in their center, a collar 4 being obtained by stamping all around this hole. This necklace has a
<Desc / Clms Page number 2>
slightly larger diameter. in the vicinity of the fin in order to be able to receive by interlocking the edge of the collar of the following fin.
This results in a single block with high thermal efficiency which can also be used successfully for car radiators.
SUMMARIES.
Improvements to radiant elements of the finned pipe type characterized in that:
1 The pipe traversed by the hot fluid contains a thin sheet wound in a helix.
2) A series of cut-out sheet metal wings, equidistant and arranged at a suitable distance from one another, these fins being pierced with a hole in their center, is forcibly threaded outside the pipe and a collar being obtained by stamping all around this hole.
