FIELD: heating systems of buildings. SUBSTANCE: radiator made of pressed aluminum profiles has feeding and discharge collectors and sections with vertical ribs linked to them. Collectors are identical and are fabricated from asymmetric profiled tube with displaced conduit. Collector have twin lugs put on axial ribs of sections. Sections have radial ribs uniformly arranged over circumference and panel ribs with edges bent inward. Collectors are connected to sections with use of bushings pressed into section conduits and into holes of collector. Bushings are fitted with sealing rings. Collectors may have hollow flanges. EFFECT: increased rated heat flow, reduced usage of metal and provision for leak-proofness. 1 cl, 4 dwg
