[0005] Preferably, the upper port of the air pipe is communicated with the air supply port, and the air supply port is opened laterally to reduce dust accumulation, and the air supply port is away from the ground to effectively reduce the suction of dust, dirt, leaves and sundries.

[0006] Preferably, the air pipe is fixedly provided with a filter screen frame alternately and intervally on the inner wall left and right, and the filter screen frame is fixedly provided with a net-bag-shaped elastic filter screen inside, after the external air is sucked into the heat dissipation fan, the air is filtered by the elastic filter screen inside the air pipe, effectively reducing the situation that dust accumulates on the heat dissipation fan and the copper pipe heat dissipation fin, and reducing the situation that dust adhesion leads to the decline of heat dissipation efficiency.

[0007] Preferably, the overlapping area coverage rate of the adjacent two elastic filter screens in the vertical direction is not less than 20%, so that the air entering has no direct channel to directly enter the air compression cooling cavity, avoiding the air entraining dust directly entering.

[0008] Preferably, the filter screen frame is downwardly inclined, so as to guide the circulating air.

[0009] The interval between two adjacent elastic filter screens is preferably not more than the transverse length of the filter screen frame, so that compared with the prior art, the dust entering the air compression cooling cavity and adhering to the surface of the heat dissipation fan and the copper pipe heat dissipation fin is reduced, and the heat dissipation efficiency is reduced, and compared with the single-piece filter screen, the effective filtering time and the filtering amount of the device are better.
