Definitions

  • Fig. 1a shows a front view of a radiator 1, according to the known state of art, consisting of a plurality of heating elements 2, formed by columns 3, usually having a substantially round section, which realize radiant elements, and headers 4 used as manifold elements.
  • the heating elements 2 are arranged in cascade, so that the headers 4 with holes 5 (as it can be seen in Figs. 1b and 1c) define an upper duct and a lower duct 7 for the throughflow of the heating fluid.
  • Fig. 1b shows a side view of a heating element having two columns 8
  • Fig. 1c shows a front view of a heating element having three columns 9.
  • Said duct 24 is formed during the pressure die-casting process, by introducing a properly shaped compressive element, i.e. having an ellipsoidal section, into the mould, inside the protozoon 18.
  • a properly shaped compressive element i.e. having an ellipsoidal section
  • another compressive element is introduced inside the hole 23 - which during the casting of the molten metal will be substantially tangential to the compressive element defining the duct 24 or have a small interfering degree - the material will be completely discharged out of the mould in the areas involved.
  • the area 14 that according to the known state of the art would have hindered a discharge of the molten metal is removed, due to an interference between the duct 24 and the hole 23.
  • the column 16 is engaged on the protozoon 18 and stops against a shoulder 27 obtained on the protozoon 18.
  • the seal ring 20 results in being compressed between the column 16 and the housing 19 obtained on the protozoon 18.
  • deformation 22 is made through a proper spherical punching device on the column 16 in line with recesses 21 on the protozoon 18. Therefore, the wall of the column 16 enters the recesses 21 to form deformations 22 and warranting a mechanical coupling between the columns 16 and the headers 17.
  • Fig. 6 shows a view of the header 17 where the configuration of protrusions 18 can be seen.
  • Said protrusions 18 have an internal section with an ellipsoidal configuration, i.e. characterized by a longer dimension D1 and a shorter dimension D2.
  • a shorter dimension D2 corresponding to the diameter of the usual columns 3 with round section shown in Figs. 1 and 2
  • a size of the heating element 15 for connection in series with other heating elements 15 equal to the size of the heating element 9 shown in Fig. 2 can be obtained.
  • the longer dimension D1 can be chosen so that the two columns 16 have a total surface and/or volume substantially dual to the total one of the three columns 3 shown in Fig. 2.
  • a radiator similar to the one shown in Fig. 1 can be obtained both from a functional and appearance viewpoint, characterized in that the header 17 is advantageously obtained by pressure die-casting in one piece.
  • the radiator described by way of example can be obtained using a pressure die-casting process, to manufacture the manifold element, with a considerable cost reduction compared to the usual manifold elements manufactured by casting.
  • the outside appearance after installation of the radiator according to the invention is similar to any conventional radiators obtained by steel casting, which means that said radiator can replace them for any architectural project without aesthetic changes.
  • the radiator described by way of example is specifically of a simple and fast realization, from the mechanical working viewpoint, also after the pressure die-casting of the manifold elements, in that a spherical punching device for assembly is simply required.
  • a gasket or seal ring placed between the internal wall of the columns and the housing on the protozoon of the manifold elements ensures hydraulic sealing in a similar simple manner as well as fast assembly.
  • the materials to be used can be freely selected, so as to enhance the functional characteristics of each element.
  • a suitable material for the pressure die-casting of the manifold elements is selected, other materials for the radiant elements can be chosen for improving the radiant and thermal exchange properties, such as for example steel alloys, processed as extruded or die-folded laminated welded pipes (about 430 W/m 2 radiant power), or copper alloys (750 W/m 2 ) for a still higher radiant capacity.
