Title (EN) SOLID STATE ELECTRICALLY CONDUCTIVE LAMINATE
(FR) LAMELLE CONDUCTRICE SOLIDE
Abstract:
(EN) A unitary, composite laminated article comprises an electrically insulating top layer (6) and an electrically insulating bottom layer (1). Applied to the inner surfaces of each of these layers is a barrier layer (2), (5) substantially impermeable to moisture and water vapor. A substantially continuous electrically conductive layer (3) of substantially uniform thickness is interposed between the barrier layers. The electrically conductive layer (3) is comprised mainly of carbon and is capable of emitting electromagnetic radiation when an electric current is passed therethrough. In contact with the electrically conductive layer (3) is electrical conductor means (7), (8). The top layer (6) and bottom layer (1) are sealed together to thereby form an enclosed laminate. The electrically conductive layer (3) exhibits very stable resistivity. The use of the article as a radiant heating device and a method for its manufacture are provided. The device is especially useful for personal comfort heating and as a heat source in commercial, residential and industrial establishments.
(FR) Un article lamellaire composite unitaire comprend une couche superieure d"isolation electrique (6) et une couche inferieure d"isolation electrique (1). Une couche barriere (2), (5) est appliquee sur les surfaces internes de chacune de ces couches, cette couche barriere etant substantiellement impermeable a l"humidite et a la vapeur d"eau. Une couche a conductivite electrique en continu (3) d"une epaisseur substantiellement uniforme est interposee entre les couches barrieres. La couche a conductivite electrique (3) se compose principalement de carbone et est capable d"emettre une radiation electromagnetique lorsqu"un courant electrique y passe. Des conducteurs electriques (7), (8) sont en contact avec la couche a conductivite electrique (3). La couche superieure (6) et la couche inferieure (1) sont scellees l"une a l"autre pour former une lamelle etanche. La couche a conductivite electrique (3) a une resistivite tres stable. L"utilisation de l"article comme dispositif de chauffage radiant et sa methode de fabrication sont decrits. Le dispositif est specialement utile au chauffage individuel et en tant que source de chaleur dans les locaux commerciaux, industriels, et les maisons d"habitation.
