Abstract

A multi-layered micro-channel mixer includes a base plate and a cover plate. Two inlet fluid reservoirs, two inlet channels, two groups of fluid distribution channel networks, two groups of process fluid channels, an impinging stream mixing chamber, a fluid mixing intensification channel and an outlet buffer reservoir are provided on the base plate. Two fluids are fed into the two inlet fluid reservoirs, respectively. The fluids then flow into the process fluid channels via the inlet channels and the multi-stage fluid distribution channel networks, respectively. Then the two fluid streams ejected from the opposing process fluid channels impinges upon each other in the impinging stream mixing chamber. The mixed fluid is subjected to vortex or secondary flow generated by the baffles or the internals in the impinging stream mixing chamber and fluid mixing intensification channel, and finally the mixed fluid is discharged through the outlet buffer reservoir.
