FIELD: heating.SUBSTANCE: honeycomb element is formed at least with one rolled pack of foil plates, the first end of which is connected to electric contact output, and its second end is connected to electric "mass". At least one pack consists of a set of foil plates electrically contacting between themselves, which are shaped at least partially, and thickness at least of one pack is determined jointly in the direction, in which the tops of their shaped structures face. Besides, at least one pack of foil plates has at least one bend with small curvature radius and large curvature radius; at that, in the curved section at least with one bend there formed is at least one zone of increased electric resistance, which begins from small curvature radius and occupies some part of thickness of at least one pack of foil plates.EFFECT: increasing service life of honeycomb element due to uniform heating throughout its cross section.13 cl, 5 dwg |
