Embodiment 1
In a kind of typical embodiment of the application, as shown in Figure 1, Figure 2, Figure 3 shows, a kind of return-flow structure passively declines mixed
Clutch, first entrance channel 1 and second entrance channel 2 are connected to first passage head end, and the first passage is straight channel 3,
The end of straight channel 3 is sequentially communicated three reflux units 4, the last one reflux unit 4 is connected to second channel, the second channel
For exit passageway 5；Two kinds of fluids for needing to mix are injected separately into first entrance channel 1 and second entrance channel 2, and two kinds of fluids exist
The head end of straight channel 3 carries out collisional mixing, and enters in straight channel 3 be diffused mixing immediately, flows back followed by three
It after unit 4, is flowed out finally by exit passageway 5, completes mixing；
It should be understood, of course, that when needing mixed fluid to be difficult to carry out the mixing that mixing needs to improve micro-mixer
When ability, it can suitably increase the number of reflux unit 4, but at least three, the reflux unit 4 passed through by increasing fluid
Number repeatedly shunts fluid progress, is flowed back and collision converges, raising mixed effect.
Further, the reflux unit 4 includes the first circular arc channel 401, the second circular arc channel 402 and return flow line,
First circular arc channel 401 and the second circular arc channel 402 are arranged symmetrically using the central axes of straight channel 3 as symmetry axis, the first circle
After the head end in arc channel 401 and the connection of the head end in the second circular arc channel 402, it is connected to a upper reflux unit or connection straight channel 3
End be connected to next reflux unit after the end 401 in the first circular arc channel is connected to the end in the second circular arc channel 402
Or connection exit passageway 5；
The return flow line entrance is connected to a bit of the first circular arc channel, on the first circular arc of return flow line outlet channel
Another point, when fluid flows through the first circular arc channel, a part of fluid enters return flow line from return flow line entrance, is flowing back
After mixing in channel, from return flow line, outlet is flowed out in the first circular arc channel.
It is, of course, understood that fluid is when flowing through the head end junction in two circular arc channels, it is of different size by two
Circular arc corridor diversion, by the circular arc channel of two different in width in reflux unit, the flow velocity of fluid is had differences, thus
The meet in two circular arc channels forms disturbance whirlpool, exacerbates the uneven collision of fluid, improves mixing intensity；
By the way that return flow line is arranged on width biggish first circular arc channel, Coanda effect, the first circular arc channel are utilized
In a part of fluid enter return flow line from return flow line entrance, in return flow line mix after, from return flow line outlet stream
Out into the first circular arc channel, the fluid in the first circular arc channel is further mixed, and improves the stream in the first circular arc channel
Speed increases the collision in meet.
As it is further preferred that the return flow line is arc-shaped；The width of the return flow line entrance is equal to first
The width in circular arc channel, and it is greater than the width of return flow line outlet；The arrival end of the return flow line is last to the first circular arc channel
The distance at end is less than outlet end to the distance of the first circular arc channel end；
It is important to note that return flow line be it is arc-shaped, when fluid flows through return flow line, due to centrifugal force act on,
Secondary Flow is being generated near wall, improves the disturbance effect of fluid；Return flow line exit width enters mouth width than return flow line
It spends small, improves the flow velocity in exit.
Further, the reflux unit in the reflux portion is sequentially communicated, and the first circular arc channel of a reflux unit is under
First circular arc channel of one reflux unit is located at the two sides of the central axes of first passage；
The junction of two adjacent reflux units is formed into four-way structure, and two the first circular arcs of same size are led to
Road is arranged in not ipsilateral, the asymmetry of shunting when fluid is from previous reflux unit to the latter reflux unit, to improve
Disturbance effect, it is interior in a limited space to increase mixing length by multiple reflux and collision, and realize repeatedly sufficiently mixed
It closes, and then improves the efficiency of mixing.
In conjunction with Fig. 1, the course of work of micro-mixer is described below:
Two kinds of fluids to be mixed flow separately through first entrance channel 1 and second entrance channel 2, in one end of straight channel 3
Converge, then flow through the one end for reaching first reflux unit after straight channel, fluid is in one end of first reflux unit by the
One circular arc channel and the second circular arc corridor diversion, a part of fluid enter the second circular arc channel, and another part fluid enters first
Circular arc channel；
When fluid flows through the first circular arc channel, segment fluid flow generates Coanda effect and is flowing back into return flow line entrance
It after being mixed in channel, is exported and is flowed out by return flow line, return flow line outlet is narrow, improves the fluid in return flow line exit
Flow velocity increases the disturbance of the first circular arc inner fluid passage；
When fluid in first circular arc channel is flowed out through first reflux unit end, flowed out with the second circular arc channel end
Fluid collide, further mix, mixed fluid is split again in one end of second reflux unit, and the
It is flowed out after being mixed in two reflux units from second reflux unit end；
The fluid flowed out from second reflux unit end is split again in one end of third reflux unit, and the
Third reflux unit end is reached after being mixed in three reflux units；
The fluid-mixing of third reflux unit end is flowed out by exit passageway, realizes the mixing of fluid.
Embodiment 2
In second of embodiment of the application, it is different from embodiment 1:
The width in the first circular arc channel in reflux unit is D, and the width in the second circular arc channel is 0.8D；
Return flow line throat width in reflux unit is D, and return flow line exit width is 0.5D.
The foregoing is merely preferred embodiment of the present application, are not intended to limit this application, for the skill of this field
For art personnel, various changes and changes are possible in this application.Within the spirit and principles of this application, made any to repair
Change, equivalent replacement, improvement etc., should be included within the scope of protection of this application.
