1. An arcwing circulating power guidance system comprising:
two guidance units comprising:
a first pipe part, an inner space of the first pipe part being defined with a first flow space extending along a pipe axis of the first pipe part; and
a second pipe part, an inner space of the second pipe part being defined with a second flow space extending along a pipe axis of the second pipe part, and an inner space diameter of the second pipe part being smaller than an inner space diameter of the first pipe part, causing a cross-sectional area of the second flow space in a direction perpendicular to the pipe axis of the second pipe part smaller than a cross-sectional area of the first flow space in a direction perpendicular to the pipe axis of the first pipe part;
one end of the pipe axis of the second pipe part and one end of the pipe axis of the first pipe part connecting in series with each other and being spaced apart from each other by a first angle, so that the second flow space and the first flow space communicating with each other in series; and
thereby, a pressure of an external fluid located in the second flow space being greater than a pressure of the external fluid located in the first flow space to cause the external fluid to flow continuously from the second flow space to the first flow space;
a first guidance unit of the two guidance units comprising the first pipe part and the second pipe part; and
a second guidance unit of the two guidance units communicating in series with the first guidance unit, and comprising the first pipe part and the second pipe part;
wherein another end of the pipe axis of the first pipe part of the second guidance unit and another end of the pipe axis of the second pipe part of the first guidance unit are connected in series with each other and spaced apart from each other by a second angle, so that the first flow space of the second guidance unit and the second flow space of the first guidance unit communicate with each other in series.
