Abstract
A microdevice for multistage-mixing of process fluids which has plurality of freely-detachable units connected to each other without using pipes, wherein a microchannel for flow of the process fluids and a channel for flow of a heat-exchange medium are formed in the microdevice by mutual connection of a plurality of the units and the microdevice is locally and independently temperature-controllable.
Claims20
A microdevice for multistage-mixing of process fluids which comprises a plurality of freely-detachable units connected to each other without using pipes, wherein a microchannel for flow of the process fluids and a channel for flow of a heat-exchange medium are formed in the microdevice by mutual connection of a plurality of the units and the microdevice is locally and independently temperature-controllable, the microdevice further comprising a heat-exchange region having:
- a process fluid channel having a hollow pencil-shaped structure;
- and
- a heat-exchange medium channel formed inside the hollow structure of the process fluid channel,
- wherein said heat-exchange medium and at least one of said process fluids are separated from each other by the hollow pencil-shaped structure.
A microdevice for multistage-mixing of process fluids which comprises a plurality of freely-detachable units connected to each other without using pipes, wherein a microchannel for flow of the process fluids and a channel for flow of a heat-exchange medium are formed in the microdevice by mutual connection of a plurality of the units and the microdevice is locally and independently temperature-controllable,
- wherein the microchannel for flow of the process fluids and the channel for flow of the heat-exchange medium are composed by multiple channels formed by mutual connection of a plurality of the units,
- wherein a device region of the multiple channels has a structure in which an outer tube part forms an outer wall of the microchannel and a middle tube part is formed therein, and the outer tube part and the middle tube part form the microchannel allowing flow of the process fluids in thin film-shaped flow, and
- wherein the middle tube part further has an inner tube part, and the inner tube part and the middle tube part form the channel allowing flow of the heat-exchange medium, with the heat-exchange medium after heat exchange being discharged through a cavity inside the inner tube part.
A microdevice for multistage-mixing of process fluids which comprises a plurality of freely-detachable units connected to each other without using pipes, wherein a microchannel for flow of the process fluids and a channel for flow of a heat-exchange medium are formed in the microdevice by mutual connection of a plurality of the units and the microdevice is locally and independently temperature-controllable,
- wherein the microchannel for flow of the process fluids and the channel for flow of the heat-exchange medium are composed by multiple channels formed by mutual connection of a plurality of the units,
- wherein a device region of the multiple channels has a structure in which an outer tube part forms an outer wall of the microchannel and a pencil-shaped hollow part is formed therein, and the outer tube part and the pencil-shaped hollow part form the microchannel allowing flow of the process fluids in thin film-shaped flow, and
- wherein the pencil-shaped hollow part further has an inner tube part, and the inner tube part and the pencil-shaped hollow part form the channel allowing flow of the heat-exchange medium, with the heat-exchange medium after heat exchange being discharged through a cavity inside the inner tube part.
A microdevice for multistage-mixing of process fluids which comprises a plurality of freely-detachable units connected to each other without using pipes, wherein a microchannel for flow of the process fluids and a channel for flow of a heat-exchange medium are formed in the microdevice by mutual connection of a plurality of the units and the microdevice is locally and independently temperature-controllable,
- wherein the microchannel for flow of the process fluids and the channel for flow of the heat-exchange medium are composed by multiple concentric cylindrical channels formed by mutual connection of a plurality of the units,
- wherein a device region of the multiple concentric cylindrical channels has a structure in which an outer circular tube part forms an outer wall of the microchannel and a tip-sealed cylindrical part is formed therein, and the outer circular tube part and the cylindrical part form the cylindrical microchannel allowing flow of the process fluids in thin film-shaped laminar flow, and
- wherein the cylindrical part further has an inner circular tube part, and the inner circular tube part and the cylindrical part form the cylindrical channel allowing flow of the heat-exchange medium, with the heat-exchange medium after heat exchange being discharged through a cavity inside the inner circular tube part.
