[0021] According to one embodiment of the present invention, in conjunction with the appendix Figure 1-4 As shown.

[0022] An axial flow fan with high kinetic energy conversion rate includes a cylinder 1, an air inlet shroud 4, and an air outlet shroud 5. The outer surface of the cylinder 1 is provided with an installation structure 2. The air inlet shroud 4 is located on the left side of the cylinder 1, and the air outlet shroud 5 is located on the right side of the cylinder 1. The inner wall of the cylinder 1 is provided with a drive mechanism 6. The outer surface of the drive mechanism 6 is evenly provided with a plurality of fan blades 7. The outer surface of the drive mechanism 6 and the inner wall of the cylinder 1 are both provided with stabilizing components 3. The air inlet shroud 4, together with the air outlet shroud 5, can optimize the air intake airflow, improve the air outlet airflow, form a stable flow field, and reduce energy loss, thereby effectively improving the kinetic energy conversion rate of the fan.

[0023] In this embodiment, the mounting structure 2 includes a mounting base 201, a first mounting component 204, and a second mounting component 205. The inner wall of the mounting base 201 is fixedly connected to the outer surface of the cylinder 1. Two mounting plates 202 are fixedly connected to the outer surface of the mounting base 201. Each mounting plate 202 has a mounting hole 203 on its outer surface. The outer surface of the cylinder 1 and the outer surface of the air inlet hood 4 are fixedly mounted by the first mounting component 204. The outer surface of the cylinder 1 and the outer surface of the air outlet hood 5 are fixedly mounted by the second mounting component 205. The air inlet hood 4 and the air outlet hood 5 can be mounted on the cylinder 1 through the mounting components, and the cylinder 1 can be installed in the required position, thereby realizing the easy assembly and installation of the fan, which has a portable effect.

[0024] In this embodiment, the drive mechanism 6 includes a plurality of fixed rods 601. One end of the plurality of fixed rods 601 is fixedly connected to the inner wall of the cylinder 1. One end of the plurality of fixed rods 601 is fixedly connected to a connecting plate 602. A drive motor 603 is fixedly mounted on the outer surface of the connecting plate 602. A rotating shaft 604 is fixedly connected to the output end of the drive motor 603. The outer surfaces of the plurality of fan blades 7 are fixedly connected to the outer surface of the rotating shaft 604.

[0025] In this embodiment, the outer surface of each fan blade 7 is coated with a nano-coating 8. The nano-coating 8 improves the surface smoothness of the fan blade 7 and can fill the tiny unevenness on the surface of the fan blade 7, making the surface of the fan blade 7 smoother. This helps to reduce airflow resistance, improve the aerodynamic efficiency of the fan blade 7, make the fan blade 7 rotate more smoothly, reduce energy loss, and thus improve the overall performance of the fan. The fan blade 7 is made of aluminum alloy, which has a low density and light weight, which can reduce the motor load and make it easier for the drive motor 603 to drive the fan blade 7 to rotate, reducing energy loss. The drive motor 603 is a permanent magnet synchronous motor, which is not only highly efficient and energy-saving, but also has good speed regulation performance, which helps to improve the kinetic energy conversion rate.

The inner ring of the second bearing 304 is fixedly connected to the outer surface of the rotating shaft 604. The stabilizing component 3 stabilizes the driving mechanism 6 during operation, reducing the amplitude of the shaking of the driving mechanism 6, thereby effectively improving the kinetic energy conversion rate.

[0027] Working principle: First, the air inlet hood 4 and air outlet hood 5 are installed on the cylinder 1 using the first mounting component 204 and the second mounting component 205 in the mounting structure 2, respectively. Then, the housing is installed at the position of use by using the mounting base 201, mounting plate 202 and mounting hole 203. The drive motor 603 in the drive mechanism 6 drives the fan blades 7 on the rotating shaft 604 to rotate. The drive mechanism 6 and the fan blades 7 form a fan. When the fan is running, the stabilizing component 3 increases the stability of the drive mechanism 6 and changes the effect of the air force in conjunction with the air inlet hood 4 and air outlet hood 5, thereby improving the kinetic energy conversion rate of the fan.
