[0029] For further reference, Figure 4 , the long and short side dimensions of the cross section of the air inlet 9 of the gradually converging and expanding heat dissipation channel 7 perpendicular to the wind path direction gradually decrease along the wind direction of the wind path; the long and short side dimensions of the cross section of the air outlet 11 of the gradually converging and expanding heat dissipation channel 7 perpendicular to the wind path direction gradually increase along the wind direction of the wind path; the long and short side dimensions of the cross section of the throat 10 of the gradually converging and expanding heat dissipation channel 7 perpendicular to the wind path direction remain unchanged along the wind direction of the wind path; the ports on both sides of the throat 10 are the same size as the small-diameter ports of the air inlet 9 and the air outlet 11; the air inlet 9 and the throat 10 form a gradually converging part, when the airflow passes through the gradually converging part, the airflow speed increases, the air pressure decreases, the convective heat transfer coefficient between the air and the wall of the gradually converging and expanding heat dissipation channel 7 and the heat sink 6 is improved, and the heat exchange effect is enhanced; the air outlet 11 and the throat 10 form a gradually expanding part, when the airflow passes through the gradually expanding part, the air pressure increases, the heat dissipation is enhanced, and it is helpful to release the heat more smoothly.

[0030] Preferably, a cooling fan 8 is provided in the air inlet 9 of the gradually converging and expanding heat dissipation channel 7 .

[0031] Preferably, reference Figure 2A-2B A filter screen 5 is provided at the filter heat dissipation shell 2 through which the air inlet 9 and the air outlet 11 of the gradually converging and expanding heat dissipation channel 7 respectively penetrate, which has a dust-proof effect and effectively reduces dust impurities from entering the filter heat dissipation shell 2 and affecting the normal operation of the filter body 1.

[0037] Connect the input port and the output port, and operate the filter. When the filter is running, heat is generated. At the same time, the cooling fan at the air inlet is turned on to blow out the cooling airflow. The cooling airflow passes through the tapered part formed by the air inlet and the throat in the tapered and expanding heat dissipation channel. The turbulence of the cooling airflow is enhanced, the speed is increased, and the air pressure is reduced, thereby improving the convection heat transfer coefficient between the air and the wall of the tapered and expanding heat dissipation channel and the heat sink, thereby enhancing the heat exchange effect. While the cooling airflow passes through the heat sink and exchanges heat with it, it continues to flow in the throat until it flows through the tapered and expanding heat dissipation channel. The air pressure increases, the airflow velocity slows down, the heat dissipation is enhanced, and the heat is released more smoothly as the airflow is discharged from the air outlet.
