Definitions

  • the present invention concerns a method to make a spacer element able to be inserted inside a radiating panel of a heat radiator, so as to prevent the crushing of its lateral walls during the steps to connect it under pressure with a relative connection element.
  • Heat radiators are known, such as for example a hot water heating plant, a heated towel rail or other, comprising one or more radiating panels shaped so as to define inside them a substantially closed compartment to contain a heat carrier fluid.
  • Such radiating panels are hydraulically connected by interposing, in twos, a connection element.
  • the connection element is pressure welded to the relative radiating panels, in order to guarantee the watertight seal of the connection.
  • a method is known, from the German patent DE-C2-3113208, to make a spacer element used to connect two or more radiating panels to a connection element.
  • the conventional spacer element is substantially cylindrical in shape and comprises axial and lateral apertures, which allow the passage of the heat carrier fluid from and towards the radiating panels.
  • this method provides that the lateral apertures are made by holing or shearing, with subsequent removal of material, and can be circular, square, oval or rectangular in shape.
  • DE'208 One disadvantage of DE'208 is that the lateral apertures reduce resistance to compression, since they weaken the structure of the spacer element itself.
  • One purpose of the present invention is to perfect a method to make a spacer element which is resistant to compression, without needing to increase the raw material.
  • the Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
  • a method according to the present invention is applied to make a spacer element able to be inserted between an outer wall and an inner wall of a radiating panel, containing a heat carrier fluid.
  • the method according to the invention comprises at least the following steps:
  • the method according to the present invention also comprises a third step during which the lateral wall is cut, so as to make at least a lip. This is subsequently bent towards the inside of said compartment so as to define a first lateral aperture on the lateral wall.
  • the lateral aperture is substantially rectangular in shape, and comprises two sides parallel to said longitudinal axis and two other sides substantially orthogonal to said longitudinal axis.
  • the two sides parallel to the longitudinal axis have the same length as, or less than, the inner height of the compartment.
  • a plurality of lips are made, in order to define a corresponding plurality of lateral apertures.
  • At least a longitudinal dishing is made, able to improve the spacer element's resistance to crushing.
  • an upper central aperture is defined on the upper wall, able during use to allow the passage of the heat carrier fluid.
  • the method according to the present invention comprises a fourth step during which, in the lower base, a lower central aperture is made, concentric to the longitudinal axis "X", and a fifth step during which said upper central aperture is sized, so as to give it a substantially circular shape with its center on the longitudinal axis "X".
  • the fourth step can be performed between the first and the second step or, alternatively, after the second step.
  • the fourth step and the fifth step can be performed simultaneously.
  • said first step comprises at least a sub-step, during which said cup-shaped element is deformed, so as to increase the height of the lateral wall.
  • a heat radiator 10 comprises two radiating panels 11, only partly shown, parallel to each other, and a connection element 12 located between the two radiating panels 11 and connected sealingly thereto, so as to form a hydraulic circuit.
  • Each radiating panel 11 comprises two walls, respectively inner 22 and outer 23 which define between them a compartment 18, able to contain a heat carrier fluid which, in this case, consists of a flow of hot water.
  • connection element 12 is connected to the inner wall 22 of each of the two radiating panels 11 by pressure welding. This operation takes place by means of the reciprocal bringing together of a first electrode 20 and a second electrode 21 (fig. 2), respectively positioned in contact with the relative outer walls 23 of the two radiating panels 11.
  • each radiating panel 11 Inside the compartments 18 of each radiating panel 11 a spacer element 13 is inserted, able to contrast the pressure exerted by the two electrodes 20 and 21, to prevent said two inner and outer walls 22 and 23 from deforming, so as to keep the width of each radiating panel 11 unchanged.
  • the spacer element 13 is made according to the steps described hereafter.
  • a deformation is made of said metal disk 30, in order to make a cup 31; the cup 31 has a lower base 26, a lateral wall 32 and its own longitudinal axis X.
  • the cup 31 is deformed, for example by means of a dishing operation, so as to increase the height of the lateral wall 32 (fig. 5c).
  • a first bending (fig. 5d).
  • a second bending is made (fig. 5e) so as to make an upper wall 25, substantially parallel to the lower base 26.
  • the second bending also defines an upper central aperture 17 on the upper wall 25, which during use allows the passage of the heat carrier fluid from the connection element 12 to the corresponding radiating panel 11.
  • the upper central aperture 17 is subjected to a sizing operation, to give it a circular shape with its center on the longitudinal axis X.
  • the lower base 26 can be holed in order to obtain a lower central aperture 16, circular in shape and having its center on the longitudinal axis X.
  • the lower central aperture 16 may not be made, or alternatively it may be made before said sizing operation.
  • the lower base 26, the upper wall 25 and the lateral wall 32 define inside them a compartment 24 substantially cylindrical in shape and with an inner height t.
  • lateral apertures 15, 36, 37 and 38 are also made, as described hereafter.
  • the lateral wall 32 is cut in a longitudinal direction with respect to the axis X, and subsequently in a direction transverse to the axis X, so as to obtain an H-shaped notch rotated by 90°.
  • each lip 34 is made, each of which is associated with the lateral wall 32 in a connection zone 35. Subsequently, each lip 34 is bent with respect to its connection zone 35 towards the inside of the compartment 24 so as to make a first lateral aperture 15.
  • This step is performed, in this case, three more times, so as to simultaneously make the other three lateral apertures 36, 37 and 38, arranged angularly equidistant by about 90°.
  • the spacer element 13 thus obtained is substantially cylindrical in shape and comprises the lower central aperture 16, the upper central aperture 17 and four lateral apertures 15, 36, 37 and 38, able to allow the circulation of the heat carrier fluid inside the compartment 18 of the radiating panel 11 and between the latter and the connection element 12.
  • each lip 34 has a height h with a length substantially equivalent to, or slightly less than, that of the inner height t.
  • the spacer element 13 is more resistant to the pressures applied in directions substantially parallel to its longitudinal axis X, since the upper wall 25 and the lower base 26 are supported not only by the lateral wall 32, but also by the lips 34, which are therefore able to reinforce the structure of the spacer element 13.
  • the number of lateral apertures made can be other than four.
  • the lateral apertures can also be arranged not angularly equidistant from each other.
  • the lower central aperture 16 and the upper central aperture 17 can be made in a single step, provided after the double bending of the upper portion of the lateral wall 32.
  • a plurality of longitudinal dishings 39 are made, for example by means of a punch or other pressing tool, on the lateral wall 32. These longitudinal dishings 39 are able to improve the resistance to crushing of the spacer element 13.
  • two radial holes 40 are made, for example by cutting the lateral wall 32 longitudinally and making corresponding lips 34, which are bent towards the inside of the compartment 24.
  • Each radial hole 40 has a cross section of smaller size than that of the lateral aperture 15.
  • the body of the spacer element 13 is divided into two semicircular zones, separated from each other by a transverse median plane A, in one of which there is the lateral aperture 15, while in the other there are the two radial holes 40.
  • the radial holes 40 are arranged on opposite sides with respect to another transverse median plane B passing through the lateral aperture 15 and substantially orthogonal to the transverse median plane A.
  • the spacer element 13, inserted inside the radiating panel 11 of the heat radiator 10 allows to obtain a more effective distribution of the heat carrier fluid, both in the central zone of the compartment 18 and also in the zones opposite the lateral aperture 15, that is, towards the corners and edges of the panel 11.
