ABSTRACT:

BACKGROUND OF THE INVENTION
Patent Document FR 2 741 706 describes such a device which comprises a section member welded along a generator line of the vertical supporting tube and a machined piece forming a cradle for the horizontal tube, the machined piece being welded to the horizontal tube and being fixed by dovetail assembly means to the section member welded to the vertical tube.
Such a device uses a molded supporting piece that is of complex shape and that can crack.
SUMMARY OF THE INVENTION
An object of the invention is to provide a suspension device that is simpler and that uses no complicated molded piece.
To this end, the invention provides a device for suspending a horizontal heat-exchanger tube from a vertical supporting tube, a flat section member being welded to the outside wall of the vertical supporting tube and parallel to the axis thereof, said flat section member being provided with a rounded notch for receiving a support piece for receiving said horizontal tube, wherein said tube-receiving support piece is a folded metal sheet that is folded to match the shape of said notch and to surround a portion of the outside periphery of the tube, and that has each of its ends, namely its top end and its bottom end, folded over towards said flat section member so as to be welded thereto, and wherein a collar enclosing the horizontal tube is fixed against said tube-receiving support piece.
Advantageously, each of said ends folded over towards said flat section member is provided with a cutout so that said ends embrace the flat section member and are welded thereto.
