Especially for fluid mixing in micro channels, this creation can overcome the following difficulties: flow resistance, bubble residue, low-speed mixing. [Previous Technology] The design requirements of fluid mixers are to complete fluid mixing in a small space and in a short time, with a simple design and economical processing costs and energy consumption. The mixing of fluids can be divided into two categories according to their energy characteristics: active and passive mixing. The so-called active mixing means that in addition to the force that drives the fluid's movement, another external force is applied to cause the mixing effect. The external force may disturb the fluid from the surface; deform and move the structure; and even pre-inject the second-phase material into the fluid from the inside. Disturb. The passive type directly causes the fluid to mix by relying on the force that drives the fluid to move. A prior art, patent number (US 2511291), as shown in the first figure, was invented in 1950 AD as a device for mixing hot and cold water. The cold and hot water enter the mixing chamber ⑽ through (01) and (02) respectively, and are divided by the influence of the structure, which are (⑷, (⑹; recombination into (〇6). Using several times of division and merging, the Strong mixing behavior, increase fluid_contact area, to achieve the purpose of mixing here and Berry. The advantage is that for the mixing of fluids of this size, it has excellent mixing effect. 'But for low flow rate and small diameter fluid mixing The channel structure is a bit complicated. Another prior art, patent number (US 005813762A), as shown in the second figure, is for low-viscosity π-listening mixing, and the channel towel is added with _ separators ⑽, ⑽) The angle between the gap and the straight is between 20 degrees and 6G degrees, and the best angle is between milk and milk. This type of structure 200533413 is a type of hybrid concrete. The advantage is that the flow peak is small, but the bi-directional straight pipe towel is added with a separator, and the work is complicated. The second prior technology, patent number ⑽2189852 C1), as shown in the third figure, uses fluid to pass through the nozzle ⑽), when the flow velocity is increased, the silk flow is accelerated, and it enters the recording area and gives birth. Vortex scales of different sizes' grant increased convective mixing effect, re-entering the constriction thousand and) action produce confluence. The effect is better at high flow rates, and almost no mixing occurs at low flow rates. Suitable for the petrochemical industry where large quantities of transmission are required. ~

With the same path length and the number of turning angles, the mixing effects of the three designs, such as three-dimensional serpentine, flat_serpentine, and straight_mixer, are compared. Compared with the present invention, the mixing effect of the planar meandering shape is poor, and the mixing effect of the three channels is better; but the manufacturing process is extremely complicated and expensive. 200533413 [Summary of the invention] The present invention is a kind of fluid mixing n, which uses a single-wanted channel to combine the staggered and convergent cross-section design to produce a collision mixture. Its structure includes the upper body and the channel body on the plane. Two L-shaped import and export channels are processed before and after the mixed channel to connect the outside. The mixed channels for plane processing have several health points. For mixed measurement, the channel design of the mixed fluid is a flat design: non-destructive measurement can be performed optically through the transparent cover directly. The L-shaped import and export channels allow fine processing of parts of the mixed channels, and then link with the outside world. The meandering and cross-section staggered protrusions and convergence of the channel cross-section can be used to verify the dynamic pattern of the field, which makes the fluid stretch and wrinkle, and increases the contact area between the fluids. The repeated channel pattern strengthens the above effects. The mixed channel has the advantages of no air bubbles remaining when the nucleus is full, and can be used in the two-phase fluid of money floating particles. It can be used for chemical composition analysis or chemical synthesis, and the transmission of matter and energy. The passive > IL body combined forces can be divided into inertial forces and interface forces. When the feature scale is large, the influence of inertial force is large; when the feature scale is small, the interface force cannot be ignored. The influencing factors are flow rate, density, viscosity coefficient, diffusion coefficient, chemical reaction properties, and interface force. The mixed convection mechanism is the repeated stretching and wrinkling of the fluid interface. The present invention uses the characteristics of the above two fluid movements to design channels with appropriate geometric shapes and sizes to generate the above-mentioned mixing mechanism. The use of meandering and channel cross-sections to create a separate flow pattern, which results in the stretching and wrinkling of fluids, increases the contact area between fluids, and reuses repeated channel patterns to enhance its effect. [Embodiment] The fluid mixer actually designed in this case is shown in Figure 4. After the mixed fluid enters the fluid mixer via (11) and (12) respectively, after the L-shaped turning, it enters from (13) and (14). A single meandering and cross-section staggered and convergent mixed channel. The L-shaped channel is designed to allow the fluid to enter the fluid mixer from the side. The mixing channel is larger than the mixing channel and externally takes over, eliminating the need for the fine mixing channel to join the external channel. difficult. After the mixed fluid co-flows at (15) to produce mixing, after turning at (16), 200533413 === ready to continue the channel recording and turning at ⑽, at (⑺, due to the sudden — and ii $ secret force The change, coupled with the non-sliding characteristics of the wall and the fluid, the resulting instability of the streamline, the longitudinal lion of the body, the lateral velocity gradient of the channel, and the mixed flow, which are helpful for the mixed flow. The amplitude is extremely large, and the flow driving pressure and pressure are sufficient to overcome the pressure of the channel and change the surface pressure. At high flow rates, the cake flow and even the reverse biaxial return zone can help the fluid to bend. Secondary curling. Continuation-a series of identical channels twisting and zooming to produce the same effect, the fluid is mixed in the finish, and Zhao finally mixes the channels on the side of the stream, diverting people and the channels). The fifth figure is the schematic diagram of the combination of the upper case and the channel body (23) in the case. The upper cover is a flat and thin plate surface and is combined with the thermal fusion wire. (The material of the L-shaped canals at the places of the upper case and the lower case is for the body to enter from the side. The fluid mixer enables the upper cover to be a flat shape, avoiding complicated processing, 'increasing the tightness of the joint between the upper cover and the channel body, and eliminating the difficulty of the upper cover (22) and the channel body ⑵) being aligned. After mixing the paste fluid of the present invention, the concentration changes, and experimental measurements and numerical simulations are performed based on the degree of concentration change and the results are compared with long straight tubular and _ ^ state fluid mixers, the design dimensions of which are shown in Figures 6 and 7, respectively. . In the experimental design, due to the direct correlation between the concentration and the gray level, the gray level of the fluid is captured and processed. The selection of the working fluid is mainly deionized water, and a small amount of edible pigment Red No. 6 and edible thickener (sodium cellulose oxalate) are added to the deionized water as red liquid. 0 · 1968, 0 · 4106 (% w / w); In addition, a small amount of edible thickener (sodium cellulose oxalate) was added to deionized water, which is a transparent liquid, and the mass ratios of the thickener were 0 · 4614 (% w / w). Distinguish the gray-scale value distribution of two liquids co-current, as an indicator to judge the degree of mixing. The viscosity of the red liquid and transparent liquid is 4.78xlO_3N · s / m2; the working fluid is driven by an injection pump (KDS220, KD Scientific, USA). The image of the fluid mixture was taken with a digital 10 200533413 camera (Olympus -㈣,] aPan). 》 M_flow phase count 剌. 2, 0_ 4, 0.8, 1.6, 3.2 and 6.4 ml. Figures 8 to 13 show the actual mixing images of the fluid mixers of the original filament and gorges cranes at a flow rate of 0.2 and 6.4 € liters per minute. The experimental results show that the mixing situation of 'sew on Sanguandao' is close at low flow rate; but at high flow rate, the mixing effect of the long straight channel becomes worse. The effect of the fluid mixing H becomes better. Compared with Jun shape, the Zhao-Mixer combined with the staggered and convergent cross-section of the single-jun channel design reduces the material, that is, it produces a mixed-enhanced reinforced mixing fairy; and the performance is higher at higher flow rates. for. With her long scales and her serpentine road, this fortune is more mixed, but there is no problem of remaining bubbles or stagnant fluid, which can save a lot of time and space. Figure 14 shows the results of the CFD-RC ™ simulation, comparing three different geometric shapes. 1§ 'where (26), (27), and ⑽ are long straight, meandering shapes, and those designed by the present invention. The simulation results of the mixed flow of the meandering channel and the truncated and misaligned flared non-convergent shaped fluid. Among them, the meandering and zooming flow channel of the present invention shows the best mixing result between the three in the simulation results. The hypothetical conditions of this simulation are: ridden Zhao, incompressible particles, constant viscosity coefficient and diffusion coefficient, constant gravity, neglecting the fluid without chemical change. The financial programs are mainly continuous, momentum and roll equations. The boundary conditions are non-slip (non-slip) walls, the speed of the channel inlet is uniform flow, the inlets on both sides of the channel are white and black water, and the flow rate is 0.4 ml per minute. In the estimation of the mixing degree, the concentration changes after the frequency mixing, and the county difference of the concentration is calculated and normalized, so that when the defined value of the mixing degree is 1, it is completely mixed, and when the value is 0, it is completely unmixed. The fifteenth figure is the relationship between the mixing degree and channel position of the three mixers. Among them, (29), ⑽) and ⑻ are long straight tube shape, Lai type and turn riding design. 11 200533413 Channels combined with cross-sections to read the projectile __set the distribution on Zhao Lingban, position 2 5 xlO-3 Eight feet a- / ^ are in the direction of 1 axis. 5x10 Α feet are brother-points, and the interval for subsequent analysis is 2 training and 3 meters.
