There are two fixing screw holes 2 provided on the left side of the top of the heat dissipation main body 1, and the dust prevention device 3 is snap-fitted and installed on the top end face of the heat dissipation main body 1; the heat dissipation main body 1 includes a frame body 11, an installation groove 12, and a heat dissipation fan 13. The top of the frame body 11 is snap-connected to the dust prevention device 3, the installation groove 12 is located on the inner end face of the frame body 11, and the heat dissipation fan 13 is fixedly installed in the installation groove 12.

[0020] The dust prevention device 3 includes a support frame 31, protective plate pieces 32, dust-proof plate pieces 33, insertion rods 34, clamping blocks 35, and recessed grooves 36. The support frame 31 is arranged on the top end face of the heat dissipation main body 1. There are more than five protective plate pieces 32, and the protective plate pieces 32 are arranged on the end face of the support frame 31. The dust-proof plate piece 33 is horizontally installed at the bottom end inside the support frame 31. There are two insertion rods 34, and the insertion rods 34 are located on the left side of the bottom of the support frame 31. The clamping block 35 is fixedly installed on the right end face of the support frame 31, and the clamping block 35 is snap-fitted and installed with the end face of the heat dissipation main body 1. The recessed groove 36 is arranged on the end face of the clamping block 35.

[0021] The dust-proof plate piece 33 includes a frame 331, a strong magnet 332, and a filter cotton layer 333. Strong magnets 332 are provided on both sides of the top of the frame 331, and the strong magnets 332 attract the end face of the support frame 31. The filter cotton layer 333 is fixedly arranged on the inner end face of the frame 331.

[0024] Working principle: When the heat dissipation main body 1 is installed in the instrument for heat dissipation, the heat dissipation fan 13 can work to generate negative pressure, and the negative pressure generated by the instrument's operation flows outwards, enabling the instrument to be cooled and operate normally. Then, the filter cotton layer 333 intercepts the dust from the outside to prevent dust from entering the interior of the instrument and affecting its use. When the dust adhered to the end face of the filter cotton layer 333 needs to be cleaned, the recessed groove 36 can be pulled to drive the clamping block 35 to move outwards and disengage from the heat dissipation main body, so that the entire support frame 31 can be taken out upwards. Then, the frame 331 can be removed to clean the filter cotton layer 333. The frame 331 can be adsorbed on the bottom of the support frame 31 by the strong magnets 332. The support frame 31 can be inserted into the top of the heat dissipation main body 1 through the insertion rods 34, and then the clamping block 35 is used to clamp the side end of the heat dissipation main body 1, facilitating the disassembly and assembly of the dust prevention device 3 to clean the dust on the end face of the filter cotton layer 333.
