A fan device is provided with a fan (10) that generates an air flow, a rotor core (20) that is provided on the outside in the radial direction of the fan (10), a stator core (40) that faces the rotor core (20), a housing (30) that forms an inner peripheral surface (31) that surrounds the fan (10) and that has an accommodation space (32) that accommodates the rotor core (20) and the stator core (40) therein, and a compressor (70), the inner peripheral surface (31) having a cylindrical surface (31a) and a nozzle surface (31b), a cooling flow path (Pc) for guiding compressed air to the accommodating space (32) and a shell-side flow path (Ph) for guiding compressed air to a boundary blow-out opening (33) formed near the boundary between the cylindrical surface (31a) and the nozzle surface (31b) are defined in the shell (30), and the boundary blow-out opening (33) faces the direction in which the compressed air is blown out along the nozzle surface (31b) in the flow direction.

    风扇装置具备产生气流的风扇(10)、设置于风扇(10)的半径方向的外侧的转子铁芯(20)、与转子铁芯(20)对置的定子铁芯(40)、形成包围风扇(10)的内周面(31)且在内部形成有收容转子铁芯(20)及定子铁芯(40)的收容空间(32)的壳体(30)、以及压缩机(70),内周面(31)具有圆筒面(31a)和喷嘴面(31b),壳体(30)在内部划定有向收容空间(32)引导压缩空气的冷却流路(Pc)、以及向形成于圆筒面(31a)与喷嘴面(31b)的边界附近的边界吹出口(33)引导压缩空气的壳体侧流路(Ph),边界吹出口(33)朝向在流动方向上以沿着喷嘴面(31b)的方式吹出压缩空气的方向。
