  • Air-blowing device
    Patent number: 10605261
    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.
