[0026] It should be noted that, by setting the wind shield in a split manner, the cooling fan 3 is fixed on the cover body 2 in advance. When the cover body 1 needs to be installed, the external docking piece 8 is inserted into the docking groove 5 on the cooling fan 3, and then the cover body 1 is put on it along the docking piece 8. The docking piece 8, the docking groove 5, and the matching hole 7 have the same shape, thereby realizing the centering setting of the cover body 1 and the cooling fan 3, realizing the center alignment of the wind shield and the cooling fan 3, avoiding the obstruction of airflow or the generation of turbulence, and improving the cooling effect of the cooling fan 3.
[0027] Preferably, a wind shielding ring 9 is provided inside the cover body 2 and on the periphery of the cooling fan 3 , and a threaded ring 10 is provided inside the cover body 2 near the four corners and on the periphery of the wind shielding ring 9 .
[0028] It should be noted that the wind protection ring 9 is provided to block the surroundings of the cooling fan 3, thereby effectively avoiding air leakage around the cooling fan 3. The threaded ring 10 is provided with a thread inside, so that in the subsequent process, the cover body 1 and the cover body 2 2 can be locked together.

The inner wall of the cover body 1 is provided with a step portion 2 19 outward, and the step portion 2 19 is symmetrically provided with a card block 20 that cooperates with the card slot 12.
[0040] It should be noted that when the cover body 1 and the cover body 2 are matched together, the threaded ring 10 and the threaded ring 2 18 are fitted together, and a locking screw can be used to pass through the threaded ring 10 and the threaded ring 2 18 to achieve mutual locking between the cover body 1 and the cover body 2 2, wherein the clamping block 20 will cooperate with the clamping slot 12 to better match the cover body 1 and the cover body 2 2 together.
[0041] Detailed usage and effects of the above embodiment:
[0042] When the fan 3 is in the center of the cover 2, the fan 3 is in the center of the cover 2. When the fan 3 is in the center of the cover 2, the fan 3 is connected to the cover 2 at the center. When the fan 3 needs to be installed, the docking piece 8 is inserted into the centering plate 4 on the fan 3 so that it is inserted into the docking groove 5 and arranged vertically. The docking piece 8 remains stationary and cannot rotate at this time. The docking plate 6 on the cover 1 is brought close to the docking piece 8 so that the matching hole 7 and the docking piece 8 match each other. When the matching hole 7 can pass through the docking piece 8, it means that the fan 3 and the cover 1 are now aligned. The cover 1 and the cover 2 are close to each other, the wind protection ring 1 9 and the wind protection ring 2 16 fit together, the block 20 and the slot 12 fit together, and finally the cover 1 and the cover 2 will be completely fitted together, and the two are also assembled. The threaded ring 10 and the threaded ring 2 18 fit together, and the two are locked together using the locking screw to achieve the centering connection between the fan 3 and the wind shield.
