Description

[0002] Axial flow fans are widely used in ventilation of factories, mines, tunnels, cooling towers, vehicles and ships. They can also be used for ventilation or heat dissipation in metallurgy, chemical industry, light industry, food, medical equipment, mechanical equipment and civil buildings. They can also be used as free fans.

[0003] The existing axial flow fans generally set the impeller in a cylindrical wind tube. Due to the strong rotation of the air flow in the wind tube, when used as a free fan, it will generate a lot of air flow noise and vibration. At the same time, the blown air flow will quickly scatter due to the lack of the restraining effect of the pipeline, showing the phenomenon that there is wind at a close distance and the wind speed drops sharply at a slightly longer distance. It cannot meet the ventilation and cooling needs of users. In addition, for some special cases that need to be installed against the wall, the general axial flow fan wind tube cannot obtain sufficient air suction area, which will also cause the air volume to fail to reach the required working conditions. At the same time, its fixed structure is not convenient for quick disassembly for maintenance.
