Abstract: A blower has a blower fan and a half shroud. The blower fan supplies air to a heat exchanger. The heat exchanger has a core that performs a heat exchange between a heat medium and the air. The half shroud covers a part of the core and defines an air passage extending from the heat exchanger to the blower fan. A blocking plate is disposed in a non-overlapping portion in which the half shroud and the core are located not to overlap with each other. The blocking plate prevents the air, which is blown by the blower fan, from flowing into an upstream area of the blower fan in a flow direction of the air through the non-overlapping portion.

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.
