The runoff double-wheel effect or double-wheel effect is a new way of wind energy conversion.
First of all, it is a double-wheel structure. Compared with the horizontal axial fan, it is a radial fan. Like the existing vertical shaft fan, the blades are arranged along the long axis, and the wind is used to rotate directly. The single-wheel vertical-axis wind wheel has opposite torques due to the simultaneous reception of wind power by the blades on both sides of the shaft, which cancel each other out, and the output torque is not large. It is designed as a double-wheel structure and installed close to it, and it operates synchronously. The original vertical shaft torque output depends on the hydrodynamic shape of the blade and then changes to the use of rotation between the two wheels to generate vortex force. The two wheels leverage each other and push each other. ; And the opposite wind flow between the two wheels can be blocked from each other, and then it is distributed to the outside of the two wheels in turn, so that the outer sides of the two wheels can get superimposed wind flow, so the outer edge of the two wheels can have a high linear velocity. Due to the wind speed, the mutual assistance of the two-wheel structure and the active use of the characteristics of the wind produces the “two-wheel effect”.
Compared with some single-wheel structure fans, the design of passive reduction of impeller rotation and reset resistance, such as additional shielding method and movable pitch pitch, reflects the characteristics of active use of wind power. Therefore, the invention not only has a practical function to promote the research and development of wind power utilization, but also has new significance in fluid mechanics. It opens up a new space for the development of wind energy and is an invention with a basic nature. This double-wheel fan has the advantages of simple design, easy manufacturing and processing, low revolutions, lower center of gravity, good safety, low operating cost, and maintenance. Easy, no noise pollution and other obvious features, it can be widely popularized and popularized to meet the needs of China’s energy conservation and emission reduction, and has great market prospects.
