Provided is an axial fan including a first fan unit including a first housing, and a second fan unit including a second housing. Each end portion, in a rotation axis direction, of the axial fan has a base portion. A shell portion between the base portions is formed by the first housing and the second housing. A coupling structure of the first and second fan units includes a first structure, and a second structure provided to the second housing. At least part of the first structure protrudes from the first housing in the rotation axis direction. The first structure can fit into the second structure when the first and second fan units come closer to each other to rotate about the rotation axis. At least part of the coupling structure is embedded in the shell portion.

Axial fan

There is disclosed an inline axial flow fan including at least first and second axial flow fans and arranged in an inline manner along an axial direction of a rotational shaft of a rotational driving apparatus. A first flow control grid is arranged in a gas discharge side of the first axial flow fan, and a second flow control grid is arranged in a gas discharge side of the second axial flow fan. The first flow control grid has a stator blade having a smooth circular arc leading edge shape matching a circular arc shape of the stator blade of the first axial flow fan and a trailing edge shape extending in parallel with a gas flow direction. The second flow control grid has a stator blade having a smooth circular arc shape matching a circular arc shape of the stator blade of the second axial flow fan.
