At the same time, the ring-shaped air duct 2 is equipped with a closed ring structure, with air inlets and air outlets at the upper and lower ports, respectively. It can guide the airflow to pass through the surface of the heat dissipation fins 3, which helps to dissipate heat and ensures the stable operation of related components during operation.
