Abstract
Radiator, particularly for heating rooms, including a main body defined by several radiating elements (3) having hot fluid flowing therein, each of the radiating elements being defined by at least a first and second sheet elements (6,7) having a plurality of apertures (9) for reducing the temperature on the external perimetric surface of the radiating elements; at least one of the apertures (10), besides the reduction of the temperature on said external surface, prevents the deformation of the sheet of the radiating elements while welding together the first and second sheet elements.
Claims10
A radiator comprising:
- a plurality of elongated upright radiating elements connected to one another in succession, each of said elements comprising:
- a pair of sheets each having an upper and a lower hub defining respective openings and communicating with fluid passages formed in the respective radiating element, said sheets of each radiating element being welded together around each of said hubs and along a path which defines a passage extending between said hubs;
- and
- deformation means for reducing temperature along perimeters of said radiating elements including apertures formed between said hubs and said perimeters, at least one of said apertures being an arcuate aperture located in a deformation sensitive region around said upper hub for preventing deformation of said sheets upon welding of said sheets around said hubs.
