Definitions

  • Subject of the invention is an apparatus consisting of one or more continuous strips of conductive material, es- pecially copper, of constant width, their thickness being measurable in microns, with a high ratio between width and thickness, laid in lengths side by side with enough space between them for electrical insulation. Said strips are joined to two contacts that can be con- nected to a source of electricity, such as a main network.
  • the strips may be laid in the form of a serpentine or spirally or in some other way according to preference. Said strips can be produced by electroplating or can con ⁇ sist of thin metal sheets cut into strips and laid sub- stantially parallel to allow space for insulation.
  • the strips are laid on a panel of insulating or conducting material.
  • the panel is coated with an insulating layer.
  • the panel is made of anodized alumi- nium.
  • the panel may be flat or curved, rigid or flexible.
  • It may be fitted with means for fixing it to the surface of surrounding structures such as walls and ceilings.
  • the strips can be submergedin the structure of the building.
  • the ratio between the overall diffusing surface of the strips of conductive material and the power of electric current can be calculated so as to maintain maximum temperature of the strips to make pos ⁇ s i ble the use of supporting and coating materials which have low temperatures of combustion such as wood, cloth, paper, plastic material and others.
  • the invention offers evident advantages.
  • Heating commences almost immediately, uniform heat being given off by the surfaces created in the above manner.
  • the cost of the heating body is much less than that of other kinds of heaters at present in use. There is no need for a heat diffuser, normally essential, as heat is produced, emitted and spread by a single body. The source of heat is easily created whether this is a sheet cut in strips, bands of metal or made by electro ⁇ pla ing. Heating bodies may even be placed in direct contact with the structure to be heated, therefore requiring no ther ⁇ mal chain.

  • Fig.3 The same radiator when finished with a decorative covering .
  • Fig.4 Panel-type radiator with a spiral conductor, front view.
  • Fig.5 The same as Fig. 4 seen from the side.
  • the radiator 10 contains a panel 11 of aluminium with an anodized layer 12.
  • the copper strip 13 of constant thick ⁇ ness and width, is laid on said layer. Thickness is measurable in microns.
  • Said strip forms the serpentine 14 whose lengths are placed side by side and separated by a space 15 equivalent to that required for electrical insulation.
  • the ends 16 and 17 of the serpentine are connected to the contacts 18 and 19 and through them to the main electri ⁇ city network by means of wiring 35 and a plug 36. On closing the circuit electric current in the serpentine is transformed into heat but avoiding the concentration that would produce very high emperatures.
  • the large surface area spreads warmth throughout the environment without any necessity for a heat diffuser.
  • Fig. 3 illustrates how the panel can be finished with a cloth covering 40.
  • Figures ** and 5 illustrate a different version 20 com ⁇ prising the aluminium panel 21 and an anodized layer 22.
  • the strip 23 forms the square spiral 24 with its several turns separated one from another by sufficient space 25 for electrical insulation.
  • the ends 26 and 27 of the spiral are joined to contacts 28 and 29 for connection to the main source of electri ⁇ city through the wiring 30 and plug 31.
