Definitions
- the present invention pertains to a technological field where two or more of fluids such as liquids and gases are mixed to obtain a mixed fluid. More specifically, the present invention relates to a technology to obtain this mixed fluid in the order of micrometer rapidly.
- a fluid mixer and a method for forming a mixed fluid as described in the preamble portions of patent claims 1, 2, 6 and 7, respectively, have been known from WO 02/102502 A .
- This micro-reactor includes multiple flat plates appropriately stacked on each other. Each flat plate is provided therein with multiple flow paths as grooves, the flow paths being substantially Y-shaped, and being connected with each other. In this way, a bifurcation portion on the upper side of the Y form of one of the flow paths is connected to a convergence portion on the lower side of the Y form of another one of the flow paths (see, for example, Fig. 2 and Fig. 10 in JP-11-511689 A ).
- multiple flat plates provided with through holes are stacked on each other, and the arrangement and shape of the through holes are devised in a way that two types of fluids are mixed by repeating the convergence and division as passing through the through holes (see, for example, Fig. 1 and Fig. 2 in JP-2002-346353 A ).
- the number of flat plates provided with the through holes need to be increased to some degree, the plate being stacked on each other so as to homogenize the mixed fluid in the order of micrometer. Nevertheless, such an increase in the number of stacked flat plates increases the thickness of the micro-reactor, and decreases the controllability on the internal temperature of the reactor. In such a case, it becomes difficult to control the chemical reaction that proceeds while involving endothermic and exothermic reactions caused by the mixing of the two types of fluids.
- An object of the present invention is to provide: a compact fluid mixer having an excellent temperature controllability, and high productivity of forming a highly-homogenized mixed fluid; and a method for forming such a mixed fluid.
- the multiple introduction paths into which a first fluid and a second fluid are introduced make it possible to treat mixtures of the two types of fluids in the multiple confluence paths arranged in parallel simultaneously.
- the multiple confluence paths arranged in parallel have the serial n number of stages with the bifurcation paths in between. Fluids are bifurcated after passing through the confluence paths at each stage. Half of the fluid thus bifurcated is converged with half of another fluid adjacent in the parallel direction, this adjacent fluid having been bifurcated similarly. These bifurcation and convergence are repeated to increase the degree of mixing the fluids without increasing the number of stages serially. Accordingly, a large number of serial stages are not required, and thus, the pressure loss accompanying the flowing of the fluids is decreased. Furthermore, since the number of the multiple first fluid and second fluid introduction paths arranged in parallel are easily increased in this configuration, it is easy to increase the amount of the first fluid and second fluid to be introduced.
- the flow paths through which the first fluid, the second fluid, and the mixed fluids flow are easily formed highly densely, and also the flow paths can be formed on two or three substrates. Thereby, the flow paths occupy only a small space, and have more specific surfaces at the same time.
- the present invention makes it possible to provide: a fluid mixer which is small in size, and which has an excellent temperature controllability and a high productivity of forming a highly-homogenized mixed fluid; and a method for forming such a mixed fluid.
- a fluid mixer 10 of the first embodiment is configured of a delivery plate 50 as well as a first flow-path plate 30 and a second flow-path plate 40 that are stacked on the delivery plate 50.
- the fluid mixer 10 configured in this manner receives a first fluid and a second fluid from inlet paths 51, 52, respectively, in the delivery plate 50. Then, the fluids flow through flow paths 31, 42 (see Fig. 2 as necessary) formed in the respective flow-path plates 30, 40, and the fluids are mixed with each other. Consequently, the fluid mixer 10 outputs the fluids as a mixed fluid from an outlet path 54 in the delivery plate 50.
- the first flow path 31 is formed into a groove shape by carving one surface (lower surface in the drawing) of the first flow-path plate 30.
- the second flow path 42 is formed into a groove shape by carving one surface (upper surface in the drawing) of the second flow-path plate 40.
- the first flow-path plate 30 and the second flow-path plate 40 are brought into contact with each other on those surfaces where the flow paths are carved. Thereby, formed are flow paths (see Fig. 2 as necessary) through which the first and second fluids flow and mix together.
- a sealing groove 33 is carved in the first flow-path plate 30 as surrounding the first flow path 31.
- a sealing groove 43 is carved in the second flow-path plate 40 as surrounding the second flow path 42. According, by inserting a sealing member 25 into the sealing grooves 33, 43, the fluids flowing through the first flow path 31 and the second flow path 42 are prevented from leaking out.
- sealing grooves 53, 53 are carved in the delivery plate 50.
- the sealing grooves are for inserting sealing members (unillustrated) disposed between the delivery plate 50 and the second flow-path plate 40.
- the sealing grooves 53, 53 are carved as surrounding a group of first dividing holes 57 through which the first fluid passes, a group of second dividing holes 58 through which the second fluid passes, and a group of third dividing holes 59 through which the mixed fluid passes.
- fastening holes 35, 45, 55 are provided at the respective peripheries of the first flow-path plate 30, the second flow-path plate 40 and the delivery plate 50.
- the fastening hole is for inserting a fastening member (the illustration is omitted) which fixes these plates stacked on each other.
- positioning holes 36, 46, 56 are provided for positioning the first flow path 31, the second flow path 42 and the dividing holes 57, 58, 59 as predetermined (see Fig. 2 as necessary).
- the material of the first flow-path plate 30, the second flow-path plate 40 and the delivery plate 50 can be appropriately selected among, for example, metals, silicon, glasses, plastic materials, in accordance with the fluids.
- the dimensions such as the width; depth, and the like of the flow paths 31, 42 preferably range from approximately several tens of ⁇ m to several mm.
- a method of etching, machine processing, or the like can be appropriately selected.
- the flow paths 31, 42 are disposed on a two-dimensional plane. Accordingly, the fluid mixer 10 is in a plate-like form, and has a large specific area as illustrated. Thus, the fluid mixer 10 has an excellent characteristic of a temperature controllability.
- the entire fluid mixer 10 may be installed in a thermostat (unillustrated), or the fluid mixer 10 may be provided on the top and bottom flat surfaces with a heat adjustment means such as a heater, a Peltier device or a hot water jacket (unillustrated).

- the multiple second-fluid introduction paths 12 (4 in the drawing) are arranged alternately with the first-fluid introduction paths 11, thereby forming a group.
- the first bifurcation path 13 is formed of an end of the first-fluid introduction path 11 bifurcating into two in the first-fluid flowing direction, as well as an end of the second-fluid introduction path 12 bifurcating into two in the second-fluid flowing direction. These ends are disposed alternately in parallel, thereby forming a group of first bifurcation paths 13.

- the multiple nth confluence paths 20 are disposed alternately in parallel, thereby forming a group.
- a mixed-fluid discharging path 21 is formed of the nth confluence path 20 positioned at the end (last stage) of the fluid-flowing direction and extended.
- the mixed-fluid discharging path 21 is a portion to discharge the fluids mixed by repeatedly converging and dividing the first fluids and the second fluids at each stage multiple times (n times), and is connected with the third dividing hole 59 in the delivery plate 50 (see Fig. 1 ).
- Fig. 3(a) is a plan view showing the first flow-path plate 30 observed from the top surface of the fluid mixer 10 (see Fig. 1 ).

- the flow paths 31, 42 through which the first fluid and the second fluid flow to form the mixed fluid can be configured by stacking at least two flow-path plates. Moreover, the converging and dividing of the fluids are repeated while the fluids flowing through these flow paths 31, 42 are curved only to a small extent. Thereby, the pressure loss in the fluids is small, and it is easy to let a large amount of fluids flow. Furthermore, the flow paths are expanded two-dimensionally on the flat surface. Thus, the area generating and receiving heat is large, and the flow paths have an excellent characteristic on a heat controllability.
