Definitions

  • the invention relates to a radiator essentially characterized by a bimetal part consisting of a steel core, formed by the heating liquid pipes, and by a die-cast aluminium coating.
  • the radiant elements can be assembled by direct contact of one-piece forms seamless, with reversible mounting and with a sturdier constrution, to be mounted in succession by means of axial cylindric threaded couplings passing in the end volute parts of the elements of the higher and lower convectors to allow continuity of the steel duct.
  • the invention foresees a modular radiator, with a new and advanced technology, to be proposed for all types of setting, in particular for central, indipendent or differential heating systems and at checked temperature, thus allowing fundamental advantages both during building and as well as management is concerned with lower production costs, energy and fluid savings and lower maintenance costs.
  • the invention carries out a considerable simplification since it does not require interposition parts among the elements and inside avoids the direct contact between the heating water and the aluminium, thus avoiding hydrogen formation and consequently no gas venting are required.
  • the thermal efficiency of the radiant unit is optimized and the desired temperature achivied in less time, moreover lightweight structures are allowed with more compact- nes and strenght which increase the enjoinment of the product and its duration in time.
  • Essential characteristic of the invention is the adoption of a bimetal radiator in which the steel core carries a very good system of ducts for the heat fluid while the external aluminium coating ensures all the advantages of this material such as the easy treatment its low cost and weight, the high thermic efficiency without the disadvantages that would occur if the same material would be used to form the heating fluid ducts.
  • the invention foresees a bimetal modulus with steel core which forms the elementary component for the heating water ducts, integrated in a die-cast aluminium coating.
  • This elementary duct component consists of two symmetrical conduits 1 with intermediate parallel lengths and with terminals converging into counterposed main parts 2 and 3, with threaded mouths 4 and front part with annular dishings 5 which, in composition, respectively determine the higher and the lower collectors.
  • the present radiator avoiding the direct contact of the water with the aluminium, does not permit the hydrogen formation whereas the use of its vertical transport canals with symmetric and perfectly cylindrical scheme allows a quick air bleeder and avoids gas venting. A reversible particularly compact and strong structure results.
  • the aluminium coating is formed by a system of fins: the front one 6, with rounded reentering terminals, and the behind one 7 with the interposed transversal one 8 containing the steel core made of the elementary duct system, equipped on both walls, on four lines, with fins 9 with continuous and separate lengths 10.
  • the structure is completed on the lower and higher end with fins 11 and 12 fitted on fittings 13 and 14 which operate also as beads which characterize the higher and lower parts of the radiating units with reticular visual effect and allowing a plastic effect particularity in connection with the presence of an interposed continuous exposing wall formed by the set of the front fins 6.
  • the radiating unit can be mounted by assembling the forms in direct contact on the mouths of the duct lengths 2 and 3 by imposing the axial joints 15 with thread 16, the seal being allowed by the O-Ring 17 fitted in volumetric fit seats formed by counterposed annular dishings 5 which have been foreseen in front of the mouths. Consequently, since the O-Ring 17 does not underlies to mechanical strain, its longer life is allowed and the trim position of the mounted radiating unit is assured.
  • the unit completion can be obtained by precluding access to the non-coupling mouths with other axial joints with an inserible part 8 with thread 19 and other mesh part 20.
  • a radiator with steel core is foreseen which uses tubular conduits with thickness of mm. 1,30 for the passage of the heating water from the higher collector to the lower one, and an aluminium coating obtained by means of pressure casting with a UNI 5076 alloy.
  • the present work enables the best results both as far as the finish as well as the radiating capacities are concerned.
  • the O-Ring has a proper resistance for an indefinite time at 120°C with a maximum temperature of 150 ° C for a period of about seventy weeks.
  • FIG. 1 is the side view of steel core of the element to allow the view of the conduits 1 and of a mouth with main parts 2 and 3 which form the lower and higher collectors.
  • Fig. 2 is the side view of the element.
  • Fig. 3 is its back view.
  • Fig. 4 is the section view of an element allowing to observe an inlet and the aluminium coating.
  • fig. 5 is the perspective vie of back side element.
  • Fig. 6 shows respectively the longitudinal and the transversal section of the cylindric axial joint 15 with thread 16.
  • Fig. 7 shows respectively in longitudinal section and at the head the axial joints of the non-coupling mouths.
  • Fig. 10 is the perspective view of the structure trace of a radiator obtainable by composing eight elements showing its inside duct system for the heating water and the relative O-Ring .
  • fig. 11 is a perspective particular of a radiator allowing to observe the reticular moulding structure and a precluded terminal mouth showing the mesh part 20 of the axial joint in preclusion position.
  • Fig. 12 is the perspective view of three radiators given as an example of the system.
  • the thickness and materials of the steel core as well as the aluminium coating, the sealing means and devices, the materials as well as their relevant working systems may be foreseen in different ways and according their relevant specific use requirements.
  • the radiator can be carried out in different ways, combined and integrated with other equivalent ones and fit for the purpose.
