Definitions

  • the present invention relates to a radiator and to a rpocess for making said radiator.
  • radiator defines a heating body, usually comprising one or more radiant elements, capable of emitting heat by natural convection and radiation.
  • a heating body usually comprising one or more radiant elements, capable of emitting heat by natural convection and radiation.
  • radiant elements capable of emitting heat by natural convection and radiation.
  • towel-heaters with cantilever radiant elements although the technical teaching of the invention can be applied to other types of radiators.
  • FIG. 1 a and 1 b in the art there are known towel-heaters S having two vertical collectors C1 and C2 and a plurality of radiating elements R arranged transversally and projecting with respect to the vertical collectors C1, C2 and in fluid connection with the same.
  • a heated heat carrier fluid for example water, is made sliding in a first collector C1 and then sliding in a first radiant element R through a first inlet hole F1, crossing one radiating element R (as shown in the embodiment of figures 1b and 2b ) or more radiating elements R, by suitable passages P between the radiating elements R (as shown in the embodiment of figures 1 a and 2a), and exiting through a second outlet hole F2 to exit from the second collector C2.
  • This type of known radiators are obtained from tubular metal of various shapes, mostly circular or elliptical for the collectors, and circular, elliptical or rectangular for radiating elements. Said tubular elements are subjected to cutting, drilling and closing of the ends operations to obtain the collectors and radiating elements, on the basis of the type of movement of the fluid carrier provided for the radiator (as explained in the above).
  • the shape and size of the holes are generally such to make the following resistance pressure welding between collectors and radiating elements possible and effective.
  • holes FC realised on manifolds C have a smaller diameter than holes FR realised on radiating elements R, and the following area is deformed outward (as shown in figures 3a - 3c ).
  • the collectors C and the radiating elements R it is proceeded to the assembly of the radiator S by welding a radiating element R each time on the collectors C.
  • the radiating element R is positioned on the same collectors C, it is pressed on collectors C themselves, and electric current is circulated. The heat developed by Joule effect in the contact areas melts the material of the two components C and R which are welded.
  • the success rate of the welding depends proportionally from the maximum temperature reached in the joint, and this, in turn, depends on the density and the intensity of the current circulating in the contact zone between radiating element R and collector C, it is necessary that the shape of the holes FC of the collectors C and of the of the radiating elements R is such to minimize the contact surface and that surrounds the holes F in such a way that the weld is continuous, watertight and strong enough to withstand to the test pressure for the radiator.
  • the positioning of the radiating element on the collector is very accurate, so that the contact surface between radiating element and collectors is uniform around the connection hole during the entire duration of welding.
  • a linear or angular displacement, even minimum, of the radiating element modifies the geometry of the contact zone, unbalancing the joint and irremediably compromising the welding. Besides the geometric control of the welding joint, it is necessary to precesely control even the welding parameters.
  • the electric current flowing through the joint must be within optimal value range, range that is very tight. A too high value of current would cause the reaching of too high temperatures and the consequent plastic deformation of the material around the welding joint, and in some cases this could also cause the piercing of the workpiece. A too low value of current does not allow to reach the melting temperature in any point of the joint, which then would not be welded, or it ould seem to be welded without being welded.
  • This assembly method is inherently subject to many d ⁇ awbvacks since the pressure exerted on the components during welding causes its deformation, which can sometimes be excessive. Furthermore, although potentially the welding is good under the mechanical aspect, it often happens that it is not airtight due to a difficult balancing of various factors such as the mechanical positioning, the welding current control, the just little difference from the tolerance of a hole, the excessive deformation of a component. It makes it necessary to further work the workpiece with greater costs and loss of efficiency.
  • the radiator is heated up to temperatures close to the melting point only in the connection zones between the collectors and the radiating element, while the rest of the radiator remains at room temperature. This generates tensions within the material responsible for the deformation of the components (collectors and radiating elements) and, consequently, of the whole radiator. It is therefore necessary to a further working step to recover the flatness of the radiator, generally, but not necessarily, by plastic deformation. Finally, the radiator is subjected to a pressure test and, if leaking occurs, it is repaired.
  • the crucial and critical step of the present process is the assembly of the collectors and radiating elements by pressure resistance welding, i.e. the main part of the manufacturing process of this type of radiators is today used in common manner.

  • the replacement of the pressure resistance weld with the strong brazing is particularly advantageous because of its versatility in terms of variety of sealable, and therefore realizable, shapes, the decrease of the costs and of the times and the increase of reliability and quality.
