Definitions

  • the invention concerns devices for heating by transforma ⁇ tion of electrical energy into thermal energy.
  • the ceilings of dwellings, of rooms used for civil and industrial purposes are, as is well known, often lowered for practical and aesthetic reasons by addition of light structures commonly known as false ceilings.
  • false ceilings are everywhere made of flat square modular structural parts, especially in the standard size of mm 600 x 600.
  • Purpose of the present invention is to provide a panel for electric heating, low in cost and inexpensive to run, that can be used on false ceilings with no problems of instal ⁇ lation and maintenance.
  • Subject of the invention are electric heating panels of a modular flat structure, installed by merely laying them on top of the false ceiling, internally comprising a flat body for radiant electric heat and a layer of thermally insulating material above said radiating body.
  • the structural modules preferably correspond to the ones generally used for making false ceilings.
  • the structure is a regular parallelepiped box formed of two bodies, a base and a cover.
  • the base that rests on the false ceiling is of metal, re ⁇ ferably of aluminium, while the cover is preferably of plastic.
  • the outer sides of the box are substan ially those of the cover .
  • This layer of foam resin is formed by pouring fluid resin through a hole made for the purpose in the cover, into the chamber created by the closed box and above the radiating body, said resin then expanding and filling the chamber.
  • Thermal radiation is produced by a continuous conducting body whose thickness is measured in microns, and which can advantageously be made from a continually extending strip of copper that matches with a geometrical plane, is of a constant section. with a high rat i0 : between thickness and width .
  • Said copper strip can be supported by a sheet of material or by a metal lamina rendered insulating by an anodized layer, by a sheet of insulating material or somehow else. Fixed to the ends of said copper strip are clamps that emerge from the cover of the box or are accessible from said cover.
  • the panels are preferably square or rectangular, but are especially of equal width and length, measuring about mm 600 x 600 , thickness being about 50 mm.
  • Electrical connection among the various modules laid on the false ceiling can advantageously be in series at a low voltage .
  • the heat .transferred to the environment by radiation is subs antially propagated by electromagnetic waves in a direct line, becoming transformed into heat on the absorbing bodies encountered, practically without any effect on intervening air, thus drastically reducing the heat losses that occur with other systems, especially when heat is transmitted by convection.
  • Heat when radiated from above can be limited to certain areas only , a fact which greatly reduces running costs as well as increasing efficiency.
  • the heating elements are totally static and are made of materials that practically require no maintenance. Means for diffusion of heat, at present essential, are unnecessary as it is produced and diffused by one body.
  • the radiating panels can be installed or removed from any false ceiling with the greatest ease.
  • Fig. l The radiating electric panel subject of the inven ⁇ tion, perspective view, partly cut away.
  • Fig.2 An exploded view in perspective of the above panel.
  • Fig.3 Radiating electric panels laid on a false ceiling, the modular parts being square.
  • the square box-shaped radiating electric panel 10 comprises a metal base 11 of aluminium with raised surrounds 14, and the plastic lid 12 with raised surrounds 15 and internal dimensions corresponding to the external dimensions of the base 11.
  • the radiating electric body 13 formed of a sheet of fibre glass 16 on which, by means of an electroplating process, a layer of copper 17 has bene laid in the form of a serpentine. Said sheet is made to match with the surface of the basel l.
  • clamps 20,21 Fixed at the two ends 18, 19 of the serpentine 17 are the clamps 20,21 consisting of a base 30 with an externally threaded head 31, a central pin 32, a lower ring nut 33, a cylindrical body 34 internally threaded at its two ends, a ring nut 35 threaded internally and externally, and a hexagonal externally threaded bushing 36.
  • the base 30 is fixed to the radiating body 13 by screwing up the lower ring nut 33, onto which isscrewed the cylin- drical body 34 which also acts as a spacer and can be fixed to the cover 12 by screwing on the head 3.5.
  • the central pin 32 remains in line with said clamp. Screwing the bushing 36 onto said ring nut therefore makes possible a stable connection for the end of an electric wire to said pin 32.
  • the copper strip is very fine, its thickness being measured in microns.
  • the false ceiling 40 in Fig.3 is formed of crossed beams 41 and 42 which form square spaces 45 closed by the mod ⁇ ular square parts 46 of aluminium, with raised edges 47. Above said parts are laid ten radiating panels at 22 volt, like 50-55, subject of the invention, the external dimen- sione of which practically correspond to the internal dimensions of the parts 46.
  • Charac eristics of the radiating panels 50-55 are the same as those of panel 10 already described. It will be seen that two parallel rows have been formed respectively comprising panels 50-52 and 53-55. For each panel there are pairs of clamps 20,21 and 22,23. The panels in the two rows are connected in series by cables 70,71 fixed to the above clamps 20,21 and 22,23. Clamps 21 and 23 on panels 52 and 55 are connected to ⁇ gether by the cable 73. Clamps 20 and 22 on panels 50 and 55 are connected by cables 74 and 75 to the main electricity supply at 220 volt All panels are therefore connected in series and operate at about 22 volt.
  • Fig. 4 shows a false ceiling 80 made with parallel beams 81-83 hung from the ceiling by rods 84.
  • Rectangular modular parts 85 of aluminium are laid cross ⁇ wise between the beams.
  • Clamps 25 and 27 of the final panels in the rows are con ⁇ nected by means of the cable 96.
  • Clamps 24 and 26 on the initial panels in the rows are connected by cables 97,98 to main electricity at 220 Volt.

Abstract

La présente invention concerne des panneaux (10) de chauffage électrique pour locaux fermés équipés faux plafonds. La structure modulaire plane (11, 12) de ces panneaux se prête à une pose simple au-dessus du faux plafond, et comprend un corps (13) électrique chauffant par rayonnement, constitué d'une bande de cuivre (17) d'une épaisseur de l'ordre du micron, laquelle bande s'étend sur un plan, et est recouverte d'une couche d'isolation thermique (15). Les bornes du circuit électrique sont raccordées à des pinces (20, 21) dépassant de la structure. Ces panneaux, qui utilisent des tensions basses, sont connectés électriquement en série.
