AXIAL-FLOW WIND TURBINE, OUTDOOR UNIT OF AIR CONDITIONER, AND AIR CONDITIONER

摘要

Provided are an axial-flow wind turbine (100), an outdoor unit of an air conditioner, and an air conditioner, the axial-flow wind turbine (100) comprising a hub (1) and blades (2). The cross section of the blade (2) in a radial direction of the hub (1) comprises a first curve segment to a fourth curve segment (24, 25, 26, 27), which are sequentially connected, wherein an inner end of the first curve segment (24) is connected to an outer peripheral wall of the hub (1); both the first curve segment (24) and the third curve segment (26) obliquely extend in the direction close to one of a suction surface (28) and a pressure surface (29) of the blade (2); and both the second curve segment (25) and the fourth curve segment (27) obliquely extend in the direction close to the other one of the suction surface (28) and the pressure surface (29) of the blade (2). The axial-flow wind turbine (100) can reduce an air flow loss and noise, and improve aerodynamic performance.
