Abstract

Static micro-mixer comprises a stack of several foils and/or plates lying over each other; mixing units; heat exchanger units; and lines for at least two material streams to be mixed. Preferred Features: The foils and/or plates have passages and are made from metal, metal alloy, plastic, ceramic and/or glass. The stack is placed in a container. The plates and/or foils are joined together by welding, diffusion welding, laser welding, soldering, diffusion soldering and/or adhering. The passages are formed by punching, embossing, cutting eroding, etching, plasma etching, laser ablating and/or by LIGA techniques.
