[0022] The heat dissipation assembly 6 includes a housing 7, which is fixedly installed on the outside of the enclosure 1. A circular air intake grille 8 is fixedly installed through the side of the housing 7 away from the enclosure 1. A drive motor 9 is fixedly installed at the bottom end of the side of the housing 7 away from the enclosure 1. A drive shaft 10 is rotatably installed inside the housing 7, and the output shaft of the drive motor 9 movably passes through the housing 7 and is fixedly connected to one end of the drive shaft 10. A positioning frame 15 is fixedly installed at the bottom end of the housing 7, and the drive shaft 10 is rotatably installed inside the positioning frame 15. A fan blade 11 is fixedly installed at the end of the drive shaft 10 away from the drive motor 9. A connecting pipe 12 is provided on the side of the fan blade 11 away from the drive shaft 10, and the end of the connecting pipe 12 away from the fan blade 11 is fixedly inserted through and extends into the interior of the enclosure 1 and is fixedly connected to the inner wall of the enclosure 1. Three heat dissipation copper pipes 13 are evenly fixedly installed inside the enclosure 1 and at the top of the connecting pipe 12, and the tops of the three heat dissipation copper pipes 13 are fixedly inserted through and extend into the enclosure 1. At the top of the housing 1, inside the three heat dissipation copper pipes 13, heat-conducting fins 14 are uniformly fixed and installed. At the top of the housing 7, a drive shaft 16 is rotatably installed, with one end of the drive shaft 16 movably passing through and extending into the housing 1. The end of the drive shaft 16 inside the housing 1 is rotatably connected to the inner wall of the housing 1. A sealed bearing 17 is rotatably installed on the outside of the drive shaft 16, and the sealed bearing 17 is fixedly installed through the housing 1 at the point where the drive shaft 16 passes through. Inside the housing 1 and outside the drive shaft 16, three agitators 18 are uniformly fixed and installed, and each agitator 18 consists of six blades.

[0024] Working principle: During operation, the drive motor 9 is started, driving the drive shaft 10 to rotate. The drive shaft 10 drives the fan blades 11 to rotate. The rotating fan blades 11 draw in external air through the circular air inlet grille 8. Then, the rotating fan blades 11 blow air into the connecting pipe 12. The airflow enters the connecting pipe 12 and is divided upwards into the three heat dissipation copper pipes 13. The heat from the lubricating oil inside the housing 1 is transferred to the heat-conducting fins 14 and the heat dissipation copper pipes 13. Then, the upward-blown airflow blows the heat out of the housing 1. At the same time, the drive shaft 10 drives the drive wheel 19 to rotate. The drive wheel 19 drives the transmission belt 21 to move, the transmission belt 21 drives the transmission wheel 20 to rotate, the transmission wheel 20 drives the transmission shaft 16 to rotate, and the transmission shaft 16 drives three agitators 18 to agitate the lubricating oil, so that the lubricating oil achieves a uniform heat dissipation effect. This allows the lubricating oil inside the gear transmission box to be cooled and dissipated during use, avoiding a decrease in lubricating oil viscosity and a thinning of the lubricating oil film. This ensures that the lubricating oil can provide sufficient lubrication and protection for the gear structure, ensuring the normal operation of the gear transmission box and thus achieving better practicality.
