Abstract: An air-blowing device has a blower fan that is an axial fan located on a downstream side of a heat exchanger in an airflow direction and supplies air to the heat exchanger and a shroud that supports the blower fan and forms an air passage extending from the heat exchanger to the blower fan. At least one side of a periphery of the heat exchanger is arranged to overlap with an outermost peripheral portion of the blower fan that is outermost in a radial direction of the blower fan when viewed in the airflow direction. The shroud has an air-introduction part that is (i) disposed, in a portion in which the ring part and the connection part connect to each other, on a surface of the connection part facing the heat exchanger and (ii) formed concentrically to be centered at a rotational axis of the blower fan. A part of the air-introduction part protrudes outwardly from a periphery of the connection part in the radial direction of the blower fan when viewed in the airflow direction. A protruding part is provided in the connection part on a boundary between the air-introduction part and a portion other than the air-introduction part.

Abstract: A blower fan includes a plurality of blades radially extending from a boss provided at a rotary center and spaced apart from each other in the rotational direction, and a ring portion connecting outer peripheral ends of the blades in a ring shape. A radially outer end part at an end on an air-flow upstream side of the ring portion is positioned outward in a radial direction of a rotary shaft in the blower fan, as toward the air-flow upstream side. Thus, the blower can prevent the backflow air from being swirled, thereby reducing noise.

Abstract: A blower fan includes a plurality of blades radially extending from a boss provided at the rotary center and spaced apart from each other in the rotational direction, and a ring portion connecting outer peripheral ends of the blades in a ring shape. An inner peripheral wall surface of an end part on an air-flow downstream side of a cylindrical portion is disposed on the outside in a radial direction of the rotary shaft in the blower fan, with respect to an end part on the air-flow downstream side of the ring portion. The end part on the air-flow downstream side of the cylindrical portion is positioned outward in the radial direction of the rotary shaft, as toward the air-flow downstream side. Thus, the blower can prevent the backflow air from being swirled, thereby reducing noise.
