Title:
CERAMIC HEATER
Document Type and Number:
Japanese Patent JPS5663790
Kind Code:
A
Abstract:
A flexible barium titanate ceramic PTC heater for use in, for example, an intake pipe of an internal combustion engine to heat the air-fuel gas mixture is formed as a thin disc-shaped ceramic sheet constituted by a plurality of individual coplanar ceramic segments having interior edges positioned in spaced side-by-side relationship. The juxtaposed edges of the ceramic segments are united to each other by a flexible, heat-resistant, electrically non-conductive rubber band disposed in the space between the segments and bonded thereto by an electrically non-conductive adhesive to form the segments into a thin disc-shaped sheet which can be flexed without causing flexing of any of the individual segments. The ceramic heater is positioned in a metallic casing with one planar face thereof bonded to the inner surface of the casing by an electrically conductive adhesive. A stainless steel wool cushioning member engages the other planar face of the ceramic heater to support the heater in the metallic casing.
