Abstract
A blowing device includes: an axial fan; and a fan shroud housing the axial fan. The fan shroud includes an air inlet part into which an air flow is introduced, the air inlet part having a shape corresponding to a peripheral shape of a heat exchanger, and an air outlet part from which the air flow introduced into the air inlet part flows out. The fan shroud further includes a passage formation part to define an air passage through which air introduced from the air inlet part flows to the air outlet part. The passage formation part has at least one rib projected toward the heat exchanger. The rib is defined within a range corresponding to a narrow portion where the air inlet part and a peripheral part of the axial fan are close to each other in a radial direction of the axial fan.
