[0002] Vertical fans generally have strong wind power, and the airflow they blow out is relatively concentrated, forming an airflow column. The air is stirred by the airflow column so that the air can circulate and circulate. They are generally used in large public and closed places. In addition, modular fans are also widely used in air-conditioned rooms, which can circulate the air in the room and achieve indoor temperature balance. However, when transporting vertical fans, due to their special shape of "large at both ends and small in the middle", they need to be packaged in packaging boxes that far exceed their volume. This will greatly affect the actual container loading volume of the fan and increase the transportation cost. However, the actual volume of the vertical fan is not large, but because of its special structure, the fan as a whole needs to be fully packaged in a packaging box that far exceeds the volume of the vertical fan.
