摘要： An improved high intensity electricl resistance heater unit comprising one or more elongate thin metal foil ribbons adapted to be heated to a high temperature by passage of electricity therethrough, a thermally insulating rigid backing for supporting each ribbon, the backing having an elongate channel in a front face thereof for receiving the ribbon with side edges of the channel being undercut to form side grooves to receive and contain longitudinal side edge portions of the ribbon to support the same along the length of the channel while leaving the major surface of the ribbon unobstructed for heat radiation therefrom. A plurality of ribbons may be mounted in the backing with all electrical metal connectors being shielded within the backing from exposure on the back face of the backing material. The ribbons may be transversely corrugated and the configuration, e.g., amplitude, of the corrugations varied along the length of the ribbons to vary the heat output along the length of the heater unit, if desired.
