[0026] In the present invention, reference is made to Figure 5 The top of the inner wall of the side of the heat dissipation cylinder 17 is fixedly connected to a support frame, the bottom of the support frame is fixedly connected to a guide fan 36, the top of the support frame is fixedly connected to a rotating shaft 37 extending to the top of the upper air guide shell 11, the outer wall of the side of the rotating shaft 37 is fixedly connected to the rotating fan blade 12 located above the upper air guide shell 11, and the top of the rotating fan blade 12 is fixedly connected to a protective cover.

[0027] Among them, reference Figure 4 A cooling unit extending to the interior of the heat dissipation drum 17 is fixedly connected to the bottom of the lower air guide shell 9. The cooling unit includes several heat-conducting drums 21. Every two upper and lower adjacent heat-conducting drums 21 are threadedly connected. The interior of the heat-conducting drum 21 is filled with a cooling solution 23 and a cooling solute 22.

[0028] Among them, reference Figure 3 The cleaning mechanism includes two connecting plates 15 distributed up and down. The side outer wall of each heat dissipation drum 17 is slidably connected to two cleaning plates 18 distributed up and down and corresponding to the connecting plate 15. The side outer wall of the connecting plate 15 is fixedly connected to a movable plate 19 corresponding to the cleaning plate 18, and the cleaning plate 18 is rotatably connected to the side inner wall of the movable plate 19.

[0029] Among them, reference Figure 6 and Figure 7The side outer wall of the side wall plate 3 facing the inside of the cabinet 1 is fixedly connected to two symmetrically distributed internal temperature-sensing tubes 2, and a partition 28 is fixedly connected to the inner wall of one end of the internal temperature-sensing tube 2. A piston plate 26 is slidably connected between the partition 28 and the internal temperature-sensing tube 2, and the outer wall of one end of the piston plate 26 is fixedly connected to a pressure rod 25 extending to the outside of the internal temperature-sensing tube 2.

[0030] When the present invention is used: during daily operation, the external wind force will drive the rotating fan blades 12 to rotate, and then drive the heat dissipation drum 17 to rotate.

When the temperature is lowered, the cooling solute 22 will be re-precipitated. At the same time, when the temperature inside the cabinet 1 changes, the temperature-sensing expansion gas 27 will expand and compress, thereby driving the movable plate 19 and the cleaning plate 18 to move up and down and clean the outer wall of the heat dissipation drum 17, preventing dust from accumulating on the outer wall of the heat dissipation drum 17 and affecting the heat dissipation effect of the heat dissipation drum 17.
