    (54) Sectional radiator for heating and relevant manufacturing method


    (57) A sectional radiator for heating and a relevant manufacturing method are described. The radiator is made up of elements (2) formed by the extrusion of a primary aluminium alloy and joined between themselves by separate collector pipes (8) which are also formed by the extrusion of primary aluminium; the jointing between the elements (2) and the collectors (8) is done by means of tubular inserts (15) provided with packings (17) being fixed into holes (13) in the collectors (8) and in the central tubes (3) of the elements (2), in applying a certain pressure and carrying out spot welding between the different parts. The collector pipes (8) can be fitted with protective covers (12), applied by sliding into slots and snapping shut.
