(54)	Method for producing radiant groups for thermal radiators

(57) A method for producing radiant groups (1) for thermal radiators includes first, die-casting of a pair of bodies (20) which form a pair of end heads (2) of a radiant group (1). Each body (20) has a cavity (21) which sets in communication a plurality of parallel channels (22) extending from the body (20). The cavity (21) communicates also with a pair of pipe stubs (23), opposite to each other and with the axis perpendicular to the laying plane of the channels (22) axes. Then, the pipe stubs (23) are threaded, so that respective couplings (4) connecting with the adjacent radiant grcups (1), can be screwed thereto. Afterwards, the cavity (21) of said body (20) is closed on the side opposite to the channels (22). Finally, the tapered mouths (30) of respective tubular radiant elements (3) are firmly joined to said channels (22) of the heads (2), arranged coaxial with the channels (22).
