The cooling fan 6 is then set in the middle of the chassis 1 and air is taken in from the front side of the chassis 1 and discharged to the back side (back panel and side panel) of the chassis 1, forming three-way heat dissipation ducts at upper, middle and lower levels, so that heat can be discharged from the equipment in time, effectively reducing the impact of temperature on the life of the equipment, and the middle duct effectively separates the main control board module from the high-heat generation module below, so that the main control board runs stably and the performance of the device is guaranteed.

The air flow blown by the cooling fan 6 enters the space where the main control board module is located through the air flow inlet 230, forming an upper air flow duct (see attached Figure 5 Arrow A points to the main control board module 2 .
