Abstract
Abstract In a preferred embodiment, a series of parallel vertical steamconducting pipes are covered on one side thereof with a metal contoured sheet of an area sufficient to be contoured to the profile of the pipes to an extent making possible the snapping-on of the sheet onto the pipes, together with top and bottom covers respectively to cover the tops and bottoms of the pipes to thereby substantially conceal them from view, and the metal sheet being connected to the respective pipes by heat-conducting metallic connectors.

Claim 1
Independent Claim
219 words
A radiator unit comprising in combination: a continuous pipe element preshaped into a plurality of serially interconnected substantially parallel sections spaced apart predetermined distances from one-another consecutively spaced one after the other and interconnected with preceding and following ones of the serially interconnected substantially parallel sections by respective interconnecting pipe portions of the pipe element such that flow space through the pipe element is serially continuous throughout the sections and interconnecting portions, said interconnecting portions being located at each of opposite ends of adjacent interconnected sections; a resilient metal sheet extending in a plane substantially parallel to the longitudinal axes of said sections, and having the sheet profile-contoured to substantially circumscribe in series each of said sections such that said sheet is mounted on said sections by snap-on intimate connections between opposite end ones of said interconnecting pipe portions; and first and second end-cover elements, the first end-cover section being shaped to fasten enclosingly over the interconnecting pipe portions located at one end of the plurality of sections and the second end-cover section being shaped to fasten enclosingly over the interconnecting pipe portions located at an opposite other end of the plurality of sections; said pipe element being substantially circular in cross-section through said sections and pipe portions, and said sections each being substantially straight along its longitudinal axis.
