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.
