Mixing and/or vaporisation device and corresponding manufacturing method

摘要

Mixing and/or vaporizing device comprises a tubular body (8) having an axial end to which are fixed blades (9) which protrude radially inward in the peripheral direction. The tubular body is produced together with the blades from a single sheet metal body (11) by deforming. Independent claims are also included for the following: (1) Method for the production of a mixing and/or vaporizing device; and (2) Exhaust gas device with the mixing and/or vaporizing device. Preferred Features: The blades overlap in the peripheral direction producing a coaxially arranged surface (12). The blades are structured so that a core region (10) is formed with a central opening (21).
