Definitions

  • the present invention relates to an accessory of a radiator for room heating, whether of the type with water, electrical or mixed, braze welded or projection welded, notwithstanding the shape and the sections of the heating elements of which it is formed.
  • radiators of the type described above comprise a plurality of heating elements (tubular or stamped sheet metal) in connection with a delivery manifold and a return manifold for the circulation of a carrier fluid.
  • the study of the configuration of the parts of which the radiator is composed is essentially aimed at maximising the thermal exchange surface and aiding the formation of convective hot air motions which in addition to the thermal exchange contributions by conduction and radiation increase the thermal yield of the radiator.
  • a limit to thermal yield is established by the current regulations on the subject which limit the surface temperature of the exposed parts of the radiator to a maximum value in order to prevent the danger of burns for the user.
  • the technical aim of the present invention is therefore to produce an accessory of a radiator for room heating which overcomes the technical drawbacks found in prior art.
  • an object of the invention is to produce an accessory of a radiator for room heating which allows the efficiency of the radiator to be improved, optimising thermal exchange by conduction, by radiation and by convection.
  • Another object of the invention is to produce an accessory of a radiator for room heating which allows more versatile regulation of the operating temperature of the radiator and greater saving in the running costs thereof.
  • a further object of the invention is to produce an accessory of a radiator for room heating which allows the radiator to be aesthetically improved.
  • the accessory in conformity with the present invention allows the thermal exchange surface to be increased and creates a series of channels which aid the formation of convective motions.
  • radiator 1 for room heating having an accessory 2.
  • the accessory 2 comprises at least a first type of longitudinal profile 6 in thermally conductive material, such as an aluminium alloy, for covering at least a longitudinal part 3 of the radiator 1.
  • the first type of profile 6, the longitudinal axis of which is indicated with L, has an internal side wall 7 with a shape at least partially matching the perimeter side surface 4 of the part of radiator 3, an external side wall 8 suitable to considerably increase the thermal exchange surface of the radiator 1, and fins 9 for remote connection between the internal side wall 7 and the external side wall 8, delimiting with the internal side wall 7 and the external side wall 8 longitudinal channels 10 suitable to aid the formation of convective hot air motions.
  • the channels 10 develop for the entire longitudinal length of the first type of profile 6.
  • the first type of profile 6 has a rectilinear longitudinal axis to adapt to a part of radiator 3 with rectilinear longitudinal development.
  • the first type of profile 6 preferably also has guiding means 11 for longitudinal insertion on the part of radiator 3.
  • the guiding means 11 comprise angular formations 12 of the external 8 ( Figs. 1-3 ) or internal 7 ( Fig. 4 ) side wall of the first profile 6 configured so as to prevent lateral extraction of the first type of profile 6 from the longitudinal part of radiator 3.
  • the angular formations 12 develop from the opposite side ends 13 of the external 8 ( Figs. 1-3 ) or internal 7 (Fig. 5) side wall and face each other frontally at a distance so as to delimit a longitudinal groove 14.
  • At least a second type of profile 5 is provided to be applied to the end of the first type of profile 6.
  • the second type of profile 5 is provided with openings 15 for ensure and aid the convective flow of the hot air.
  • the second type of profile 5 can have means of known type, for example with mechanical coupling, for joining the first type of profile 6 to a third type of longitudinal hollow profile 17 which has an internal structure analogous to or even differing from that of the first type of profile 6.
  • the second type of profile 5 preferably describes an angle of 90° for an orthogonal junction between the first type of profile 6 and the third type of profile 17.
  • the second type of profile 5 in particular has a preferably square (as shown) or curved longitudinal axis.
  • the accessory 2 seats at least one accompanying element therein for operation of the radiator 1.
  • An accompanying element can comprise a light display 19 having programming buttons and an electrical wire 21 for connection to a remote electronic controller 20.
  • radiator 1 is of the mixed type for heating a room for civil use.
  • the radiator is provided with heating elements 22 connected at the ends to a delivery manifold 23 and to a return manifold 24.
  • a first electrical resistance R1 is incorporated in the delivery manifold 23, with its supporting base 25 fixed externally to the lower end of the delivery manifold 23, while a second resistance R2 is incorporated in the return manifold 24, with its supporting base 26 fixed externally to the lower end of the return manifold 24.
  • the delivery 23 and return 24 manifold are connected inferiorly by a hydraulic fitting 27 having a two-way delivery 28 for the water, a two-way return 29 for the water and a seat 30 to seat a thermostatic valve.
  • a profile of the first type 6 covers the delivery manifold 23
  • a profile of the first type 6 covers the return manifold 24
  • a profile of the second type is applied to each longitudinal end of the two profiles of the first type 6, an upper profile of the third type 17 is connected between the two upper profiles of the second type 5, and a lower profile of the third type 17 is connected between the two lower profiles of the second type 5.
  • Each of the lower profiles of the second type 5 contains a corresponding supporting base 25 or 26.
  • the lower profile of the third type 17 contains a hydraulic fitting 27.
  • the profile of the first type 6 covering the return manifold 24 contains, preferably in one of its channels 10, the display 19 with the programming buttons which protrude from a front window 31 of the profile of the first type 6 covering the return manifold 24.
  • the remote electronic controller 20 of the display 19 is contained in the lower profile of the third type 17, and this remote electronic controller 20 is connected to a switch 33, also contained in the lower profile of the third type 17 in a position substantially symmetrical with respect to the seat 30 seating the thermostatic valve.
  • the electrical connection cable 21 runs through a channel 10 of the profile of the first type 6 covering the return connector 24, through the profile of the second type 15 at the lower end of the profile of the first type 6 covering the return manifold 24, and through the lower profile of the third type 17.
  • a tangential fan is present inside the upper profile of the third type 17 which connects the upper profiles of the second type 5, the fan being optionally associated with an electrical wire resistance and which sucks air from the channels 10 both of the first profile 6 covering the delivery manifold 23 and of the profile of the first type 6 covering the return manifold 24 and expels it through a specific opening of the profile of third type 17 in which it is contained, to establish a forced convective air motion in addition to the convective air motion that is established naturally along the channels 10 through chimney effect.
  • Provision of the accessory 2 allows the distance between the hottest areas of the radiator 1 and the contact areas accessible to the user to be increased, so that it is possible to install a higher power, with respect to a conventional radiator of the same dimensions: in particular, the two resistances R1 and R2 are actuable individually or in combination on three power levels R1, R2 and R1+R2 and allow more effective and versatile temperature regulation, and saving in the running costs.
  • the thermal exchange efficiency is improved both by the presence of additional exchange surfaces created by the external side wall 8 and by the fins 9 of each profile of the first type 6 used, and by the presence of the channels 10 which optimise the formation of natural and/or forced convective air motions.
  • each profile of the first type 6 is inserted longitudinally on the corresponding delivery 23 or return 24 manifold so that the heating elements 22 are slotted along the groove 14.
  • the groove 14 can be closed by special modular comb inserts 32 which can have both functional validity to prevent dirt from accumulating and aesthetic validity to conceal the weld area between the heating elements 22 and the manifolds 23, 24.
  • the system for applying the accessory 2 to the radiator 1 can differ from the one shown.
  • the accessory 2 can be provided for this purpose with specific snap coupling members, or screw or interlocking fixing blocks or the like.
  • the first type of profile 6 can be composed of two mutually associated half-parts which allow coupling of different materials, also with different colours or surface treatments.
  • This structure aids the application of accessories such as LEDs, backlights, hooks or towel bars, retractable, or perimeter finishing profiles in any material.
  • the accessory can also comprise two elements of the first type 6 applied to the manifolds 23, 24 and optionally provided with elements of the second type 5 applied to close their ends.
  • the profiles forming the accessory can have countless shapes, dimensions, materials, colours and mechanical or galvanic surface treatments.
  • the materials used, and the dimensions can be any according to requirements and to the state of the art.
