[0050] The working principle and use process of the present application are as follows:

[0051] In the work of the cooling air supply device for chemical fiber yarn production, the main shaft rod 212 and the eccentric rotating wheel 210 inside the transmission box 220 are driven to rotate by the driving motor 100, the main shaft rod 212 rotates away from the center of the main shaft rod 212, thereby pulling each piston 250 to reciprocate inside each compression cylinder sleeve 230 through the crank connecting rod 240, and performing stroke and return motion, in the return process of the piston 250, the external environment airflow is introduced through the one-way intake valve 232 and the intake filter element 233, in the stroke motion of the piston 250, the airflow inside the compression cylinder sleeve 230 is unidirectionally guided out through the one-way exhaust valve 231, thereby using the continuous rotating motion of the eccentric rotating wheel 210 to pull the piston 250 inside each compression cylinder sleeve 230 to move, and pumping the external airflow into the air distribution ring seat 300, through the communication between the air distribution ring seat 300 and the intake pipe end 421, the compressed airflow enters the internal rotating flow intake seat 420, under the guidance of the cold air guide pipe 422, the airflow does rotating flow motion along the inner wall of the rotating flow intake seat 420 and the vortex guide pipe 410 to generate vortex; the airflow flows quickly inside the vortex guide pipe 410, when the airflow passes through the narrow horn-shaped or necked area on the surface of the cone plug 431, the flow rate slows down, the vortex begins to form, the inertia force of the airflow pulls it to the inner wall of the vortex guide pipe 410, so that it is dispersed in the vortex guide pipe 410 to form a small vortex area, in the small vortex area, the airflow and the wall of the vortex guide pipe 410 generate heat through friction, and the heat is quickly dissipated through the action of vortex, so that the temperature is effectively reduced, at the same time, since the airflow suffers resistance when passing through the vortex pipe, the heat medium will flow faster, thereby further increasing the heat transfer efficiency, with the continuous flow of the airflow, heat will be continuously transferred between the vortex pipe and the surface of the vortex pipe, thereby realizing the rapid heat dissipation of the heat, part of the airflow is released at one end of the necked cold air guide pipe 422 and then rapidly depressurized to cool the airflow, which is guided by the air outlet guide seat 500 and the fan assembly 510 to blow to the surface of the chemical fiber yarn to cool it, the structure is simple and the energy consumption is low.

[0052] Although embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and the spirit of the application, the scope of which is defined by the claims and their equivalents.
