Abstract
In a static micromixer a flow guide structure consisting of a stack of foils provided with passages formed into alternate foils so as to extend between a mixing chamber at one end of the flow guide structure and different admission chambers at the opposite end of the flow guide structure, the passages are curved so that they are all parallel at their exit ends adjacent the mixing chamber and, at their entrance ends, the flow guide structure has face areas which are inclined with respect to the exit end face of the flow guide structure at such an angle that the curved passages have all about the same length.
