Abstract: An outdoor unit of an air conditioner may include a case, an outdoor heat exchanger disposed in the case to perform heat exchange between outdoor air and a refrigerant, and a blower apparatus to blow and guide the outdoor air. The blower apparatus may include a blower fan to rotate about a shaft thereof to blow the air heat-exchanged with the refrigerant by the outdoor heat exchanger in one direction and an orifice installed in the case such that an inside and an outside of the case communicate with each other through the orifice to guide the air blown by the blower fan. The orifice may include a discharge part to guide air discharged from a front to a rear of the blower apparatus in an axial direction. A sectional area of the discharge part gradually increases from the front to the rear of the blower apparatus in the axial direction.

Abstract: A blower according to an embodiment of the present disclosure includes: a case; a fan; and a diffuser disposed downstream of the fan and guiding air, discharged from the fan, toward the discharge ports, wherein the diffuser includes: an outer wall; an inner wall spaced apart inwardly from the outer wall so that an air passage is formed therebetween; and a plurality of vanes extending radially between the outer wall and the inner wall and dividing the air passage into a plurality of unit passages, wherein the outer wall and the inner wall are formed to have areas with different radial separation distances D between the outer wall and the inner wall, such that in an area of the air passage of the diffuser in which air is discharged to a portion having a high flow resistance in the blower, the radial separation distance D increases to widen the air passage S, thereby compensating for the asymmetry of the passage inside the blower, allowing a uniform volume of air to reach the entire area of the discharge ports, and improving the performance of the blower.
