Micromixer with overlapping-crisscross entrance

摘要

The micromixer with overlapping-crisscross entrance incorporated with the grooved microchannel, is used effectively for mixing two or more fluid streams. The X-shape overlapping-crisscross inlet ports wherein two microfluidic channels contact over a small area, allow the fluid streams flow through and create the tumbling inside the micromixer. Then merging with some patterned grooves on the walls also induces swirling motion. As a result, the folding and stretching effects of the flow are augmented to amplify the fluid mixing of two or more streams of the inlet fluids within a relative short distance in the micromixer. All of the flow streams are actuated with either pressure driven by a syringe pump or capillary electrophoresis. The present invention is applicable for micro total analysis systems and drug delivery systems.
