Modular element radiator-convector

A radiator-convector comprising a plurality of assembled modular elements each of which comprises an upper sleeve member, a lower sleeve member parallel to said upper sleeve member, a plate cast integral with said sleeve members and perpendicular to a plane passing through said sleeve members, said plate having a front edge and rear edge, a conduit formed in said plate and connecting said upper sleeve member with said lower sleeve member, fins extending from the opposite sides of said plate and comprising substantially parallel fins obliquely arranged with respect to said plane and front fins provided at the front edge of said plate and forming a front wall, said front fins and the plate of adjacent elements when assembled defining air ducting vertical channels each having a lower inlet opening and an upper outlet opening and said parallel fins defining air ducting oblique channels, wherein according to the improvement said oblique channels have their lower ends open at the rear edges of said plates and their upper ends communicating with said vertical channels and wherein at the inlet openings of said vertical channels ribs are arranged which converge towards said channels.
