One point B, straight line where the waist in the trapezoidal groove section as secondary water conservancy diversion runner in same A plane and mistake waist simultaneously
Angle between upper any point and the straight line of point B is 0~10 °, so that electrolyte is substantially radially flowed as shown in the rightmost side Fig. 1
It is dynamic, improve the uniformity of electrolyte distribution.
Major flow runner design standard of the present invention are as follows: the pole electrolyte mainstream in positive and negative electrode electrode frame enters, outflux
Be arranged between secondary liquid separation runner, i.e., the anode electrolyte mainstream in an electrode frame enter, outflux and secondary water conservancy diversion stream
Major flow runner is set between road, then enters with the electrolyte liquid mainstream in electrode frame, set between outflux and secondary water conservancy diversion runner
Set major flow runner.
Preferably, the major flow runner is made of 1 or 1 or more runner, between the runner with width be 0.5~
The major flow runner floor of 10mm separates, so that electrolyte, which uniformly flows into, flows freely region, major flow width of flow path 1~
50mm, 0.5~5mm of depth；The secondary water conservancy diversion runner includes multiple secondary water conservancy diversion streams that secondary water conservancy diversion runner floor is separated into
Road, secondary water conservancy diversion width of flow path 1~50mm, 1~100mm of length, depth 0.5~5mm, secondary water conservancy diversion runner floor width 1~
50mm, 1~100mm of length, with a thickness of 0.5~5mm；The major flow runner is connected and crosses with the secondary water conservancy diversion runner
At entrance or outlet center.
The secondary water conservancy diversion runner of the entrance secondary water conservancy diversion runner and outlet is arranged in respectively at entrance and exit section, and left
Right two sides secondary water conservancy diversion flow channel length, width and depth should keep symmetrical consistent, evenly distributed to achieve the purpose that.

The principle that grade water conservancy diversion width of flow path is relatively narrow and/or depth is shallower and deeper far from end wider width and/or depth, secondary water conservancy diversion stream
Road floor change width and secondary water conservancy diversion runner are on the contrary, secondary water conservancy diversion runner depth of floor variation becomes with secondary water conservancy diversion flow channel depth
Change consistent.
The free-flowing region is located between secondary water conservancy diversion runner and major flow runner, by flowing freely the slow of region
Punching makes electrolyte uniformly flow into secondary water conservancy diversion runner；Flow freely region width 1~50mm, 0.5~5mm of depth up and down.
Preferably, the major flow runner, the secondary water conservancy diversion runner, the settable use of the free-flowing overlying regions
In the cover sheet for forming closed flow with electrode frame, 0.5~10mm of the cover sheet thickness.If being not provided with cover sheet,
Electrode frame is directly contacted with bipolar plates and to form closed flow and also may be used.
Preferably, the anode and electrolyte liquid stream enter, 1~50mm of outflux diameter.
The framework electrode zone is trapezoidal, is trapezoidal long bottom close to anode and electrolyte liquid main flow inlet side
Side, opposite survey is short bottom edge；The anode is set in the framework, electrolyte liquid mainstream enters, outflux and the primary and secondary grade
The two sides frame width of water conservancy diversion runner is 5~200mm, and the two sides frame width of non-setting above-mentioned zone is 1~100mm, electrode
Frame is with a thickness of 0.5~50mm.
Preferably, the primary and secondary grade water conservancy diversion runner and free-flowing region inner corner are with each edges intersections
Arc-shaped transition.
Electrode frame material provided by the invention can select the materials such as polyethylene, polypropylene, polyvinyl chloride, but be not limited to
This.The molding of machining engraving, injection molding etc. can be used in primary and secondary grade water conservancy diversion runner in framework, but not limited to this.
Compared with the prior art, the electrode frame structure that the present invention uses is particularly suitable with trapezoidal liquid flow battery, can make to be electrolysed
The uniformity of liquid distribution is greatly improved, to guarantee battery and pile internal-response uniformity, weakens localized heat release, drop
Hypopolarization, high electrolyte utilization rate.Particularly with high-power pile, can effective lower cost, save material.
Technical solution of the present invention bring beneficial effect
The liquid flow frame structure is simple, easy to process, has and promoting Radial Flow of the electrolyte along trapezoidal place sector
Effect improves the uniformity of electrolyte distribution, to alleviate local effect, promotes battery performance.Specifically:
It can be along vertical when electrolyte enters trapezoidal electrode zone from entrance section according to principles of fluid mechanics
It is flowed in the direction in import section, at this time due to the presence of two waists, the electrolyte of left and right ends will receive the inhibition of two waists,
So that the right and left electrolyte flow is unsmooth, electrolyte renewal rate slow stagnant area or even flow dead zone are formed, in the region
Electrolyte inside renewal rate is slow, so that active material is insufficient, and then polarizes and increase, voltage efficiency is reduced, and electrolyte utilizes
Rate reduces, and finally makes the reduction of battery overall performance.
According to trapezoidal pile design principle, as shown in Figure 1, relative to vertical inlet section, fan of the fluid along trapezoidal place
Two waists will not generate inhibition when shape Radial Flow, and fluid distrbution is the most uniform at this time, therefore secondary water conservancy diversion runner direction design
It for radial direction, can largely increase the uniformity of electrolyte distribution, and reduce pressure loss, promote battery performance.
