Problems solved by technology

[0008] However, in the case of the prior art axial flow fan, since the surface defined from the hub to the tip of the blade is a curved surface, the aerodynamic drag is concentrated at the tip of the blade to cause wake flow
This reduces fan efficiency and introduces noise

Abstract

Provided are an axial flow fan and an air conditioner. The axial flow fan includes a plurality of blades (120). The blades (120) include corrugated parts (125) on ends thereof. The corrugated parts (125) include convex portions (125a) and concave portions (125b) that are alternately arranged.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2011-0104368 filed on October 20, 2011, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to an axial flow fan and an air conditioner. Background technique [0004] Air conditioners are used to heat or cool indoor spaces. This air conditioner includes a compressor for compressing refrigerant, a condenser for condensing refrigerant discharged from the compressor, an expansion device for expanding the refrigerant discharged from the condenser, and a compressor for evaporating the refrigerant expanded by the expansion device. Refrigerant evaporator. [0005] Both the condenser and the evaporator in an air conditioner are heat exchangers in which the refrigerant exchanges heat with the surrounding air. The condenser and the evaporator may be provided in the indoor unit and the ou...
