1500609 Space heating radiators HOECHST AG 6 June 1975 [8 June 1974] 24448/75 Heading F4S A radiator constructed of a plastics material is formed from elements, each comprising fluid passages 2 interconnecting upper and lower cylindrical manifold sections 1 and arranged substantially normal to the axes of the sections. The passages either radially into the manifold sections and have a reducing diameter towards the sections. The elements are interconnected at the sections which are reinforceable by bands 3 thereabout. The passages of each element may be reinforced by continuous or intermittent webs 5 therebetween and projections 6 on the passages form abutment surfaces between adjacent elements. |
