Modular element for the production of heating radiators and process for the manufacturing
thereof |
(57) The invention provides a modular element for composing heating radiators comprising
a die-casting finned structure of aluminium, defining one, two or more vertical conduits
extending between two horizontal conduits, namely an upper and a lower, in which in
the or each vertical conduit a tubular insert is disposed, of a metal with a higher
mechanical strength and chemical corrosion resistance than the material forming the
finned structure. The inner surface of the upper and lower horizontal conduits in
said structure is lined with a layer of anticorrosive material deposited thereon after
casting the structure. The invention also relates to a process for manufacturing the
modular radiator element.
