Abstract

A micro-mixer is disclosed having at least one mixing point which is connected to an inlet channel arrangement having at least two inlet channels and to an outlet channel arrangement, and a mixing method is disclosed for at least two fluids which are supplied from different directions. With this mixer and method it is intended to achieve a rapid and predeterminable mixing of the fluids. For that purpose, a separating element which extends into a region of the mixing point in which the inlet channels run parallel to one another is provided. By this means the fluids can be kept separate from one another until their flow speeds virtually coincide in respect of value and direction. Only then are they brought into contact with one another.
