[0019] Furthermore, to facilitate multi-directional airflow guidance and heat dissipation inside the heat sink 2, both sides of the front of the inner cavity of the heat sink 2 are connected to a fan shroud 8.

Meshing bevel gears 13 are fixedly connected to the surfaces of the second mounting rod 11 and the first mounting rod 9, both inside the heat sink 2.

[0020] The specific usage steps are as follows: The device is installed in the designated position by the engagement of bolts with mounting holes 14. Then the motor body 501 is started, and the motor body 501 drives the rotating shaft 502 and several fan blades 504 to perform daily rotation and blowing. When the motor body 501 is installed in the environment for heat dissipation, water is injected into the water cooling pipe 605 by a micro water pump. The water source in the water cooling pipe 605 drives the water pressure vane 612 to rotate through the circulating water pressure. The water pressure vane 612 drives the rotating rod 611 to rotate. The rotating rod 611 drives the cooling fan blade 613 to rotate. The rotation of the cooling fan blade 613 will blow air into the heat dissipation shell 2. The air force is displaced from the heat dissipation mesh frame 615 to the outside. When the corresponding fan blade 504 rotates, the rear side of the heat sink 2 is in the negative suction area. The wind force entering the front side of the outer frame 1 from the rear side of the heat sink 2 will synchronously drive several wind force deflectors 12 to rotate. The wind force deflectors 12 drive the second mounting rod 11 to rotate. The rotation of the second mounting rod 11 drives the bevel gear 13 to rotate. The meshing of adjacent bevel gears 13 drives the first mounting rod 9 to rotate. The first mounting rod 9 drives the auxiliary fan blade 10 to rotate. The rotation of the auxiliary fan blade 10 blows the air inside the heat sink 2 from the auxiliary fan blade 10 to the front side of the outer frame 1. When disassembling and replacing the water-cooling pipe 605, rotate the ring cover 602 in the opposite direction to disengage the external threaded ring 603 from the internal threaded ring groove 601. Then, press the two pressing frames 709 by hand to move them towards the center of the filter cover 608. The movement of the pressing frames 709 pushes the central control linkage 710 to rotate. The rotation of the central control linkage 710 pushes the L-shaped plate 704 to move vertically until the L-shaped plate 704 drives the positioning pin 705 to be pulled out of the slot 706. Finally, remove the filter cover 608 and pull out the water-cooling pipe 605 in sequence.
