Corpo de colmeia com uma estrutura interna que é segura por uma moldura

摘要

A honeycomb body includes an axis along which a flow of fluid is to be conducted through the honeycomb body. At least two oppositely disposed end surfaces define the honeycomb body along the axis. An internal structure for conducting an electric current for heating is formed of at least one sheet-metal layer. Metal support configurations each support the internal structure at a respective one of the end surfaces. An electric insulation is disposed between the internal structure and the support configuration. A method for producing an electrically heatable honeycomb body includes producing at least one approximately rectangular sheet-metal layer having two opposed end edges being aligned approximately perpendicularly to an axis. Each end edge is encompassed with a folded joint having a ceramic layer resting on the at least one sheet-metal layer, to form support configurations. The sheet-metal layer and the folded joints are corrugated at obtuse angles preferably being approximately perpendicularly to the axis. The sheet-metal layer including the folded joints are layered in layers and the layers are wound about the axis. The support configurations are mounted in jacket tubes. Force-locking connections are produced in the support configurations between the layers formed with the folded joints.
