When the fan 12 is working, the air inlet end is located at one side of the filter screen 5, which effectively filters out dust and impurities in the air to prevent these pollutants from being blown to the surface of the fin 9, thereby maintaining the cleanliness and heat dissipation efficiency of the fin 9;

[0045] By pulling the handle 72 to one side, the support frame 6 and the filter screen 5 can be easily unlocked and taken out, and the installation of the new filter screen 5 is also very simple. Only by inserting the support frame 6 into the fixed frame 3 and releasing the handle 72 can the fixing be completed.
