Heating apparatus, more particularly radiator, and process for making same

摘要

The radiator is composed of laminar elements (1.1), with oval cross sections, arranged in parallel with their flat sides facing. Ports of adequate cross section to facilitate the flow of heating medium are provide top and bottom of these elements. To construct the radiator connecting tubes (2) are welded in position between the ports before the ends of the elements are closed by rolling their edges together and welding.
