| 摘要 |
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.
