[0027] The heat dissipation mechanism 200 includes a shell 201, which is fixedly connected to the top of the channel body 101, and air guide covers 202 are fixedly connected to both sides of the shell 201. The openings of the two sets of air guide covers 202 are both set downward, and air outlets 201a are opened on both sides of the shell 201. A mounting port is set on the top of the shell 201, and a fan 203 is fixedly connected to the inner side of the mounting port;

[0028] The shielding mechanism 300 includes a connecting slat 301, which is fixedly connected to the left side of the mounting slat 105, and a primary shield 302 is electrically connected to the right side of the connecting slat 301, and a connecting rod 303 is fixedly connected to the right side of the primary shield 302, and the connecting rod 303 passes through two groups of air outlets 201a, and a secondary shield 304 is fixedly connected to the right end of the connecting rod 303, and the primary shield 302 and the secondary shield 304 are both arranged opposite to the air outlet 201a, and when the two groups of filter screens 106 are respectively opposite to the channel holes, the two groups of primary shields 302 respectively shield the two groups of air outlets 201a.
