[0040] The embodiment of the present application also provides a heat dissipation method of a multi-channel laser direct writing control system, and the specific method comprises the following steps:

[0041] Step one, air impurity removal: fan 4 sucks external air into air distribution pipe 31, air is dispersed into multiple air inlet assemblies 34 through air distribution pipe 31, dust and other impurities in the air are filtered through the filtering structure in air inlet assembly 34, the air is evenly dispersed into multiple air filtering boxes 342 after passing through air distribution pipe 31, dust and other impurities mixed in the air are filtered after passing through arc-shaped filter plate 348, clean air enters into exhaust pipe 341 through the second pipeline, enters into the inside of multi-channel laser direct writing control system body 1 through the exhaust outlet of exhaust pipe 341, and is discharged through the exhaust outlet arranged on the side wall of multi-channel laser direct writing control system body 1.

[0042] Step two, adjust the longitudinal blowing angle of air flow: the output end of servo motor 5 drives cam 6 to rotate, so that cam 6 intermittently drives driving rod 35 to move downward, air inlet assembly 34 is driven by driving rod 35 to make the air outlet thereof swing up and down reciprocatingly, and air is evenly blown out. Since driving rod 35 and gap 343 are connected through rotating shafts, and exhaust pipe 341 and the inner wall of heat dissipation box 2 are connected through rotating shafts, driving rod 35 drives multiple exhaust pipes 341 to rotate downward around the rotating shafts thereof after being driven by cam 6.

When cam 6 rotates through a certain angle, lifting plate 37 is lifted by spring 38 through the elastic force, so that driving rod 35 drives exhaust pipe 341 to return to the original position. Due to inertia, exhaust pipe 341 still swings upward by a certain angle after returning to the original position, and the above process is repeated, so that air inlet assembly 34 has the ability to adjust the longitudinal blowing angle of air flow. At the same time, during the up-and-down swinging of exhaust pipe 341, ball head 345 is rotatably arranged in ball head sleeve 347, so that exhaust pipe 341 swings upward and downward while taking ball head sleeve 347 as a fulcrum, drives arc-shaped brush plate 346 to swing upward and downward synchronously, and long brush hairs on the surface of arc-shaped brush plate 346 clean the filtering holes on the surface of arc-shaped filter plate 348.
