[0027] In this embodiment, with reference to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the heat dissipation assembly 5 comprises a heat dissipation pipe 501 which is embeddedly mounted on the inner wall of the shaft body 1, the heat dissipation pipe 501 is in a U-shaped structure, a heat absorption plate 502 is arranged on the inner wall of the shaft body 1 at one end of the heat dissipation pipe 501, the heat absorption plate 502 is in a grid structure, a double-way rotary pipe joint 503 is arranged on the outer wall of the shaft body 1 at the other end of the heat dissipation pipe 501, liquid guide pipes 504 are symmetrically arranged at one end of the double-way rotary pipe joint 503, liquid pumps 505 are mounted at one end of the liquid guide pipes 504, the liquid pumps 505 are arranged on the outer wall of a liquid storage shell 506 in two groups, the liquid pumps 505 are provided with the liquid storage shell 506 at the liquid outlets, a mounting bracket 507 is mounted on the outer wall of the liquid storage shell 506, a control panel 508 is mounted on the outer wall of the mounting bracket 507, the control panel 508 is located directly above the liquid pumps 505, a grid heat dissipation plate 509 is arranged in the inner cavity of the mounting bracket 507 and on the outer wall of the liquid storage shell 506, and a heat dissipation fan 510 is mounted on one side of the grid heat dissipation plate 509 and on the outer wall of the mounting bracket 507.
