Detailed Description

The present invention will be further illustrated with reference to the following specific embodiments, which are to be construed as merely illustrative and not limitative of the remainder of the disclosure. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

Example (b): referring to fig. 1-3, a fluid parallel flow control structure includes a main pipe 100, one end of the main pipe 100 is a liquid inlet 101, and the other end is a liquid outlet 102, the main pipe 100 is communicated with a plurality of parallel branch pipes 200 along its length direction, and a communication port is formed in the main pipe 100 corresponding to each parallel branch pipe 200;

a baffle plate 103 is arranged in the main pipeline 100 corresponding to each communicating port, the baffle plate 103 is perpendicular to the flowing direction of the liquid in the main pipeline 100, and each baffle plate 103 is positioned at one side of the communicating port close to the liquid outlet end 102;

the length of the baffles 103 in the main pipe 100 is gradually increased from the liquid inlet end 101 to the liquid outlet end 102, and the baffles 103 are all positioned on the same straight line, so that the gap between the baffles 103 and the main pipe 100 is gradually decreased from the liquid inlet end 101 to the liquid outlet end 102;
