Abstract:
1. A ceramic honeycomb monolith useful for the fabrication of an electrical heating device, comprising: a ceramic honeycomb body structure comprising electrically insulating and thermally resistant materials and having a solid geometrical configuration; wherein said honeycomb body structure comprises a plurality of longitudinally extending parallel walls which extend continuously from one end of said honeycomb body structure to an opposite end of said honeycomb body structure, and a plurality of transversely extending parallel walls which traverse said plurality of longitudinally extending parallel walls and which extend continuously from one side of said honeycomb body structure to an opposite side of said honeycomb body structure such that together, said plurality of longitudinally extending parallel walls and said plurality of transversely extending parallel walls define a plurality of four-sided channels for the passage of air therethrough; wherein said plurality of longitudinally extending parallel walls and said plurality of transversely extending parallel walls are offset with respect to each other such that first end portions of said plurality of longitudinally extending parallel walls extend beyond first end portions of said plurality of transversely extending parallel walls so as to define a plurality of longitudinally extending grooves between adjacent ones of said plurality of longitudinally extending parallel walls, while second end portions of said plurality of transversely extending parallel walls extend beyond second end portions of said plurality of longitudinally extending parallel walls so as to define a plurality of transversely extending grooves between adjacent ones of said plurality of transversely extending parallel walls; and a plurality of electrical heating elements disposed within said plurality of longitudinally extending grooves and within said plurality of transversely extending grooves for heating air as the air passes through said plurality of longitudinally extending grooves, through said plurality of transversely extending grooves, and through said plurality of four-sided channels.
