Definitions

  • the present invention relates in general to radiators for heating systems, and in particular to an innovative modular element for the production of such radiators, and to the radiators obtained.
  • Heating radiators are usually composed of modular elements which are fixed together in banks, side by side.
  • each modular radiator element has a body obtainable by a die-casting process in aluminium or its alloys, and comprises at least one vertical conduit which extends between, and connects together, two horizontal conduits spaced apart in height, on lower and one upper, to enable a thermovector fluid, generally water, to flow.
  • thermovector fluid has a high corrosion level and/or is circulated at relatively high pressures
  • the chemical and physical resistance of aluminium may be insufficient.
  • tubes of other metal such as iron or steel having a higher corrosion and pressure resistance.
  • Radiators formed in this manner are also known as bimetal, the tubes inserted into their horizontal conduits being threaded to enable several modular elements to be connected together as a bank.
  • the object of the present invention is to create the conditions for forming modular elements for manufacturing radiators of the stated type without embedding additional tubes in their horizontal conduits, while still protecting the tubular aluminium or aluminium-alloy structure against corrosion and high operating pressures, with the result of obtaining lighter modular elements than the known art.
  • a modular element for composing heating radiators in accordance with the introduction to claim 1, characterised in that the upper and lower horizontal conduits of the finned structure are internally lined with a layer of anticorrosive material applied thereto by deposition following casting of said structure, before or after assembling the modular element side by side with others following a process claimed in claim 2.
  • each modular radiator element comprises a finned structure 10 produced by die-casting in aluminium or the like and configured, in known manner, to define at least one vertical conduit 11 extending between two horizontal conduits, namely an upper 12 and a lower 13.
  • a tubular insert 14 of another material, such as iron or steel, of higher mechanical strength and resistance to chemical corrosion that the aluminium forming the finned structure, is disposed in the vertical conduit 11.
  • a lining layer 15 of a corrosion resistant substance is applied to each horizontal conduit 12, 13 to protect the aluminium parts in contact with the circulating thermovector fluid.
  • Each modular element is formed by a production process comprising, after providing the tubular insert and preparing a suitable die-casting die:
  • Each modular element is then smoothed by mechanical grinding, and the ends of each horizontal conduit 12, 13 are threaded, after which, to form a bank, the modular element is connected to other modular elements by connectors engaged with the threads of the horizontal conduits, to compose a radiator 16 - Figure 3 - of the desired dimensions.
  • This anticorrosive lining layer 15 can be produced starting from a liquid or pulverulent substance applicable to the horizontal conduit surfaces by a spray gun applicator insertable and movable within the conduits.
  • the radiator 15 treated in this manner is then passed to a firing kiln to solidify and stabilize the anticorrosive lining layer.
  • the radiator can then be painted.
  • the lining layer can also be applied to each modular element individually prior to its assembly into a bank with others to form a radiator.
