The present application relates to the technical field of refrigeration apparatuses, and discloses an axial flow wind wheel, used for solving the technical problems that the air outflow volume of existing axial flow wind wheels is reduced, and the operation noise is increased due to the fact that an airflow separation phenomenon exists on the surfaces of blades in the operation process of the axial flow wind wheels. The axial flow wind wheel comprises a wheel hub and a plurality of blades; the inner edges of the plurality of blades are connected to the wheel hub, and the plurality of blades are uniformly arranged at intervals in the circumferential direction of the wheel hub; the suction surface of each blade is provided with a plurality of rows of flow guide structures, and each row of flow guide structures comprises a plurality of flow guide ribs arranged along a corresponding arc; moreover, the arcs respectively corresponding to each row of flow guide structures are concentric with the axis of the wheel hub, and are arranged at intervals in the radial direction of the wheel hub. An air conditioner outdoor unit comprises a heat exchanger, a driving motor, and the axial flow wind wheel, the heat exchanger is arranged opposite to the axial flow wind wheel, and a driving shaft of the driving motor is connected to the wheel hub of the axial flow wind wheel. An air conditioner comprises the air conditioner outdoor unit. The axial flow wind wheel disclosed in the present application is configured to provide wind energy for the heat exchanger of the outdoor unit.
