Definitions

  • the present invention concerns a spacer element insertable inside a radiant panel of a heat radiator, so as to prevent its lateral walls from being crushed during the steps when it is connected under pressure with a corresponding connector.
  • Heat radiators are known, such as for example radiators, comprising one or more radiant panels shaped so as to define inside them a substantially closed compartment to contain a heat-carrying fluid and make it circulate.
  • the radiant panels are hydraulically connected to each other by interposing, in twos, a connection element or connector.
  • the connector is welded under pressure to the corresponding radiant panels, to guarantee the fluid-tight seal of the connection.
  • spacer element comprising a spacer body, hollow inside, having a lower base, a lateral wall provided with lateral apertures and an upper base substantially parallel to the lower base, so as to define a compartment with a substantially cylindrical shape.
  • one solution provides to increase the number of the lateral apertures of the spacer element.
  • a spacer element is known, from EP 1681530 in the name of the present Applicant, provided with four and five lateral apertures.
  • Purpose of the present invention is to obtain a spacer element, insertable inside a radiant panel, that allows to increase the delivery capacity of the spacer element without diminishing its resistance to compression.
  • 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 spacer element according to the present invention which overcomes the limits of the state of the art and eliminates the defects therein, is insertable inside a radiant panel containing a heat-carrying fluid.
  • the spacer element comprises a spacer body, hollow inside, having a lower base, a lateral wall provided with a plurality of lateral apertures and an upper base substantially parallel to the lower base, so as to define a compartment with a substantially cylindrical shape and having a longitudinal axis.
  • the diameter of the lower base and of the upper base has a maximum value of 25 mm.
  • the transverse width, that is, orthogonal to the longitudinal axis, of each lateral aperture is comprised between 0.2 and 0.3 times said diameter.
  • the six lateral apertures guarantee a greater flow rate of heat-carrying fluid that passes through the spacer element compared with known configurations.
  • the number of six lateral apertures constitutes a good compromise between delivery capacity and resistance to compression of the spacer element.
  • each of the lateral apertures is angularly equidistant with respect to the adjacent one, so as to make the stream of heat-carrying fluid uniform inside the spacer element.
  • each of the lateral apertures comprises at least a lip bent toward the inside of the compartment of the spacer body.
  • the lip defines a support, or stiffening element, for the lower base and the upper base of the spacer element, increasing its resistance to compression applied between the upper base and the lower base along the longitudinal axis of the spacer element, at the same time conferring on the spacer element a greater delivery capacity compared with state of the art solutions.
  • each lateral aperture has a substantially rectangular shape, and comprises two sides parallel to the longitudinal axis and another two sides substantially orthogonal to the longitudinal axis.
  • each of the lateral apertures comprises two of said lips.
  • the presence of the second lip for each lateral aperture confers an even greater resistance to compression compared to the case with the single lip, maintaining a high delivery capacity, or in any case higher than in known solutions.
  • each of the lateral apertures has a substantially rectangular shape.
  • a spacer element 10 is inserted inside a heat radiator 11 comprising two radiant panels 12, which are only partly shown, parallel to each other, and a connector 13 interposed between the two radiant panels 12 and connected to them in a sealed manner, so as to form a hydraulic circuit.
  • Each radiant panel 12 comprises an inner wall 16 and an outer wall 17 which define a compartment 18 able to contain a heat-carrying fluid, such as for example hot water.
  • the connector 13 is connected to the inner wall 16 of each of the two radiant panels 12 by pressure welding. This operation occurs by bringing a first electrode 19 and a second electrode 20 reciprocally closer ( fig. 2 ), positioned in contact with the corresponding outer walls 17 of the two radiant panels 12.
  • the spacer element 10 is able to contrast the pressure exerted by the two electrodes 19 and 20, to prevent the inner walls 16 and the outer walls 17 from deforming, so as to keep the width of each radiant panel 12 unchanged.
  • the spacer element 10 comprises a spacer body 23, hollow inside and defining a compartment 24 having a substantially cylindrical shape ( figs. 3 and 4 ).
  • the spacer body 23 comprises a lower base 25, an upper base 26, substantially parallel to the lower base 25, and a lateral wall 27; it is also substantially axial-symmetric with respect to its own longitudinal axis X.
  • the lower base 25 and the upper base 26 respectively comprise a lower central aperture 30 and an upper central aperture 31, one of which, during use, allows the heat-carrying fluid to pass from the connector 13 to the corresponding radiant panel 12, or vice versa.
  • the lower central aperture 30 and the upper central aperture 31 have a circular shape and their center corresponds with the longitudinal axis X.
  • lateral apertures 32 are made in the lateral wall 27, all of them the same and angularly equidistant from each other.
  • the lateral apertures 32 have a substantially rectangular shape.
  • the six lateral apertures 32 entail a greater delivery capacity of the spacer element 10, obtaining an increase in the heat exchange between the radiant panels 12 and the surrounding environment.
  • Each lateral aperture 32 comprises two lips 33, parallel to the longitudinal axis X and bent toward the inside of the compartment 24.
  • the lips 33 are associated to the lateral wall 27 in a connection zone 34.
  • the lips 33 define a support for the lower base 25 and the upper base 26, increasing the resistance to compression applied along the longitudinal axis of the spacer element 10, and at the same time guaranteeing a greater delivery capacity compared with solutions known in the state of the art.
  • each lip 33 is equal to the height of the compartment 24, and is disposed in abutment with the lower base 25 and the upper base 26.
  • the configuration of the spacer element 10 in its entirety entails two main advantages: the first is the increase in the delivery capacity, the second is the increase in resistance to compression.
