Title
(EN) RESISTANCE HEATING ELEMENT WITH LARGE-AREA, THIN FILM AND METHOD
(FR) ELEMENT DE CHAUFFE PAR RESISTANCE ELECTRIQUE A GRANDE SURFACE ET A FILM MINCE ET PROCEDE D'APPLICATION DUDIT FILM
Abstract
(EN)
A large-area, thin film, resistance heating element (21, 46, 81) including a relatively rigid substrate (22, 63, 82), which will retain its mechanical properties at elevated temperatures, an electrically conductive film (26, 64, 84) deposited on the substrate (21, 46, 81), and electrical terminals (31, 66, 86) provided on the film (26, 64, 84). A metallic substrate (22, 63), such as a steel sheet, having an electrically insulating ceramic-based layer (23, 62, 83) thereon may be employed, or alternatively, a micanite plate or sheet (61) can be used. The substrate and film have an area which is sufficiently large that the heater can operate at maximum temperatures above 100 °F with a power density less than about 15 watts per square inch. The electrically conductive film is preferably a metal-oxide film, such as tin-oxide, and is used as a resistance heater in applications such as ovens (41) and space heaters (81) to allow delivery of substantial power at lower operating temperatures and low power densities for greater efficiency.
(FR)
Elément de chauffe (21, 46, 81) par résistance électrique à grande surface et à film mince, qui comporte un substrat relativement rigide (22, 63, 82) conservant ses propriétés mécaniques à des températures élevées, un film électriquement conducteur (26, 64, 84) déposé sur le substrat (21, 46, 81) et des bornes électriques (31, 66, 86) situées sur le film (26, 64, 84). On peut utiliser un substrat métallique (22, 63), tel qu'une feuille d'acier, recouvert d'une couche à base de céramique électriquement isolante (23, 62, 83), ou, selon une variante, une plaque ou feuille (61) de micanite. Le substrat et le film ont une superficie suffisamment grande pour que l'élément de chauffe puisse fonctionner à des températures maximales supérieures à 100 °F avec une densité de puissance inférieure à environ 15 watts par pouce carré. Ledit film électriquement conducteur est de préférence un film d'oxyde métallique, tel que de l'oxyde d'étain, et il est utilisé en tant qu'élément de chauffe par résistance électrique dans des applications telles que des fours (41) et des radiateurs indépendants (81) pour permettre de fournir des quantités considérables de puissance à des températures de fonctionnement inférieures et des densités de puissance faibles pour un plus grand rendement.
