摘要

The body has a set of fluid channels (12) e.g. filter element or catalyst element, that are arranged in a flow of a fluid, where the fluid channels extend along a longitudinal direction (14) and are arranged in a position transverse to the longitudinal direction next to each other. The channels are arranged above one another, and limiting walls (16) of the channels are curved related to the longitudinal direction for the formation of the body. A sequence of cross-sectional constrictions (18) and cross-sectional enlargements (20) are arranged along the longitudinal direction of the channels. The body comprises a set of fluid channels (12) e.g. filter element or catalyst element, that are arranged in a flow of a fluid, where the fluid channels extend along a longitudinal direction (14) and are arranged in a position transverse to the longitudinal direction next to each other. The fluid channels are arranged above one another, and limiting walls (16) of the fluid channels are curved related to the longitudinal direction for the formation of the body. A sequence of cross-sectional constrictions (18) and cross-sectional enlargements (20) are arranged along the longitudinal direction of the fluid channels. The fluid channels are laminated in a batch direction transverse to the longitudinal direction. The fluid channels extend along the longitudinal direction and are arranged in a position transverse to the longitudinal direction next to each other, where the limiting walls of the fluid channels are curved related to the longitudinal direction. A multi-layer winding body is rolled up in a continuous position with the fluid channels. The neighboring fluid channels are transverse to the longitudinal direction, so that the cross-sectional enlargements in the fluid channel is arranged corresponding to the cross-sectional constrictions. An entry part and an ejection part are arranged in different positions of the body. The neighboring fluid channels are reciprocally plugged using a plug, so that a fluid path of the Fluid leads by the limiting walls of the fluid channel, where the limiting walls of the fluid channels are made of partially catalytically active material. An independent claim is included for a filter system.
