Combined with a circulating airflow path, including first and second axial flow fans, air delivery pipes, distribution pipes, and air-cooled nozzles, it achieves both airflow blocking and circulation.
It achieves the blocking and circulation of cold air flow, enhances the heat dissipation effect on the film surface, achieves secondary cooling, and effectively removes heat from the film surface.
