摘要： A cross flow fan blade includes an inner edge disposed on an inner circumferential side of a cross flow fan, an outer edge disposed on an outer circumferential side of the cross flow fan, and a base part formed between the inner edge and the outer edge. The base part has a pressure face and a negative pressure face. A thickness of the inner edge is larger than 1.5 times a thickness of the outer edge. An interval between the pressure face and the negative pressure face in a direction perpendicular to the pressure face is a thickness of the base part. A maximum thickness position of the base part is closer to the inner edge than to the outer edge. When a blade chord length is L and a maximum thickness of the base part is tmax, tmax/L≤0.094, and a range of tmax/L≤0.08 is excluded.

摘要： Disclosed is a cross-flow fan including a fan rotor and a housing. The cross-flow fan has a blow-out path defined by first and second extension wall portions and two sidewalls. The first extension wall portion continuously extends from a tongue portion of the housing to the blow-out port. The second extension wall portion faces the first extension wall portion. The two sidewalls are respectively provided at axial ends of the fan rotor. The two sidewalls are formed such that the blow-out path has a narrowed portion whose cross-sectional area decreases as its cross-sectional shape changes from a rectangular shape to a trapezoidal shape from an upstream side toward a downstream side thereof, the trapezoidal shape having a portion near the second extension wall portion smaller in width than a portion near the first extension wall portion.

摘要： A blade of a cross-flow fan including leading and trailing edge portions arranged on inner and outer peripheral sides of the cross-flow, and a base portion formed between the edge portions. The edge portions are arc shaped. The base portion has a pressure surface and a suction surface. A radius of the leading-edge portion is greater than a radius of the trailing-edge portion. A maximum thickness is at a position of maximum thickness that is closer to the leading-edge portion than to the trailing-edge portion. A first thickness is at midpoint of a blade chord. A second thickness is at a position set apart from an outer-peripheral end of the blade chord by 5% of the chord length. A value obtained by dividing the first thickness by the maximum thickness that is greater than a value obtained by dividing the second thickness by the first thickness.
