Document Type and Number:
Japanese Patent JPH0359558
Kind Code:
B2
Abstract:
A self-regulating heating element comprising a tubular body closed at each end and containing two longitudinal electrically and thermally conductive flat strips arranged parallel to and spaced from each other. Each flat strip is provided along at least one longitudinal edge thereof with an abutting longitudinal resilient heat-conductive strip conforming with the adjacent surface of the inner wall of the tubular body so as to be in resilient heat-exchange contact with such inner surface for conducting heat from the flat strip to the tubular body. At least one PTC resistor is positioned between and in electrical and heat-exchange contact with the parallel flat strips, electrical terminals extending through the tubular body into contact with the flat strips. Such heating elements find particular use as immersion heaters for liquids and as the heat source in hair-curling devices.
