Definitions

  • the heating radiators include several pipes, embodying the radiating elements, positioned parallel to each other with a usually vertical orientation and connected to the ends through suitable hydraulic connecting ducts.
  • any radiator is divided into modules each one including two heads or end manifolds and a number of pipes, usually changing from three to six, connected at the ends to the manifolds so to make a row of transversal pipes in the direction of the radiator depth.
  • the end manifolds placed side by side and connected with each other, lead to the building of more pipes sets, it is to say so many sets as the pipes of each module, positioned on planes parallel to the radiator front surface.
  • the known technique to embody the radiators of the above summarily described type provides first of all for the building by moulding of half-shells destined to make any manifold once coupled.
  • Each couple of half-shells, placed in contact position is irremovably joined by traditional or laser welding. In case the welding is the traditional one the article is then to be cleaned by brushing.
  • After the insertion into the two manifolds of each module the ends of the relative pipes, these last ones and the manifolds themselves are welded.
  • the radiator building is then completed joining the several manifolds to each other by side welding or using threaded tubular connection elements, conventionally named nipples.
  • base of the present invention is to plan an heating radiator and its embodiment process to substantially avoid the mentioned disadvantages.
  • Another important aim of the invention is to plan a radiator and an embodiment process allowing to consistently reduce the manpower costs and then control the overall production costs.
  • a further aim is to plan an heating radiator with limited dimensions as to the known technique in the transversal direction of its depth, being the same the number of pipes used in this direction.
  • the heating radiator according to the invention is on the whole indicated with n. 1.
  • It includes two tubular elements embodying the radiator lower and upper end manifolds.
  • tubular elements 2 show a circular section and on one generatrix of them is obtained a line of first holes 2a longitudinally aligned and fit to house the ends of several pipes 3 forming the central set of heating elements.
  • the ends of the pipes 3 are irremovably connected through welding to the manifolds 2 so that these last ones are perpendicular to the pipes 3 themselves, that are parallel with each other.
  • tubular elements 2 show, in transverse section, a substantially oval shape, lengthened in the direction of the radiator depth. With this shape it is possible to obtain two lines of first holes 2a longitudinally aligned along two parallel generatrices so to house and connect the ends of two pipes 3 sets positioned on parallel planes corresponding to said generatrices. In this second embodiment form there are then two central sets of radiating elements.
  • radiators have two sets of pipes 4 embodying outer radiating elements parallely aligned to the only central set or the two central sets of radiating elements.
  • Each outer pipe 4 has near its end parts, irremovably connected through welding to the end manifolds 2, two side holes 4a aligned on the same generatrix and placed in connection with two second holes 2b of the same manifolds.
  • the outer pipes 4 are finally sealed in their end openings 4b by suitable caps closing elements 5.
  • the invention embody a new process being as well integral part of the present patent.
  • the end parts of the pipes 4 are joined by welding, advantageously made by electric induction, to the end manifolds 2 so to put in connection the second holes 2b of these last ones with the side holes 4a of the pipe 4 themselves.
  • the invention achieves important advantages.
  • each radiator is obtained by the union, the radiating elements being equal, with a lower number of components as to the known technique since the manifolds of the whole radiator are simply formed by only two tubular elements instead of several heads welded with each other or connected through screws, each of them by its turn requires the welding of two half-shells.
  • the radiator components connecting operations are then a lower number and then is more curbed the cost for the manpower necessary for the embodiment of the radiator.
  • the radiator according to the invention being the number of radiating elements equal, has a smaller volume in the transversal direction thanks to the particular shape of the end manifolds.
  • pipes and manifolds sections can take any other shape not shown in the drawings.
  • the double central set of radiating elements can be applied also to radiators with round or elliptical section manifolds.
