Abstract (en)
[origin: WO0112960A1] The invention relates to a mixer element (1) for a fluid that is guided in a pipe (2), especially a mixer element that is used in the exhaust pipe of an internal combustion engine. Parts of the outer current A that is adjacent to the inner surface (3) of the pipe (2) are guided towards the interior by means of an outer guide section (4) and at the same time and in an approximately common plane parts of the inner current I are guided towards the exterior by means of an inner guide section (5). The use of the entire inner surface (3) of the pipe (2) for the purpose of cooling is preferably guaranteed by at least one opening (7) that is provided in the outer guide surface (4). The invention provides a simple means for obtaining a homogeneous temperature distribution and good cooling of a fluid that is guided in a pipe. The inventive mixer element (1) is especially distinguished from known mixer elements by its compact construction.
