Microfluidic reactor for controlling chemical reaction and chemical reaction control method using the same

A microfluidic reaction device which is capable of controlling a chemical reaction, comprising:

• a plurality of microfluidic reactors wherein each microfluidic reactor of the plurality of microfluidic reactors is capable of controlling the chemical reaction between a plurality of fluids, wherein each microfluidic reactor of the plurality of microfluidic reactors comprises a housing formed of a metal material and having a predetermined volume, a unit flow path module formed inside the housing and comprising a plurality of unit flow paths, each unit flow path having N inlets, where N is an integer of 2 or more, and a single outlet such that N fluids are respectively introduced and mixed and then discharged, a branch flow path module formed inside the housing and comprising N branch flow paths which are all connected to corresponding ones of the N inlets provided in each unit flow path of the plurality of unit flow paths to uniformly branch a fluid introduced into the housing into the plurality of unit flow paths, and a collection flow path formed inside the housing, connected to individual outlets provided in each unit flow path of the plurality of unit flow paths, and collecting a mixed fluid moved from individual outlets provided in each unit flow path of the plurality of unit flow paths and discharging the mixed fluid outside the housing;
• N external distributors external to the housing and corresponding in number to the N branch flow paths, which are all connected to inlet ends of the N branch flow paths provided in each microfluidic reactor of the plurality of microfluidic reactors so as to uniformly branch with respect to the plurality of microfluidic reactors after receiving a fluid from the outside;
• and
• an external collector external to the housing and connected to all of outlet ends of the collection flow paths, each collection flow path being provided being provided in a respective one of the plurality of microfluidic reactors so as to collect the mixed fluid discharged from the plurality of microfluidic reactors,
• wherein the unit flow path module, the branch flow path module and the collection flow path are monolithically and integrally formed inside the housing in a process of stacking the housing through a 3D printing process.
