To provide a motor-integrated fan, etc. capable of favorably removing heat from a heat generating portion while suppressing degradation of fan performance.SOLUTION: A motor-integrated fan that suctions air through a suction port and blows out the suctioned air through a blow-out port, comprises: a shaft part provided at the center of a rotation shaft; a rotation part 12 that rotates about the shaft part; a duct 13 provided to an outer periphery of the shaft part; a motor 14 that causes the rotation part 12 to rotate; a coil 46 that emits heat due to the operation of the motor 14; and a cooling unit 17 that cools the coil 46 using cooling air. The cooling unit 17 includes: an air intake port 51 that takes in cooling air; an air discharge port 52 that discharges the cooling air; and a cooling stream flow channel 53 extending from the air intake port 51 to the air discharge port 52 through the coil 46. The air discharge port 52 is located at a position at which the pressure is more negative than at the air intake port 51.SELECTED DRAWING: Figure 3

    【課題】ファン性能の低減を抑制しつつ、発熱部の除熱を好適に行うことができるモータ一体型ファン等を提供する。【解決手段】吸込口から空気を吸い込み、吸い込んだ空気を吹出口から吹き出すモータ一体型ファンにおいて、回転軸の中心に設けられる軸部と、軸部を中心に回転する回転部12と、軸部の外周に設けられるダクト13と、回転部12を回転させるモータ14と、モータ14の作動により発熱するコイル46と、コイル46を冷却空気により冷却する冷却部17と、を備え、冷却部17は、冷却空気を取り込む空気取込口51と、冷却空気を排出する空気排出口52と、空気取込口51からコイル46を経て空気排出口52までに至る冷却流路53と、を含み、空気排出口52は、空気取込口51に比して圧力が負圧となる位置に設けられる。【選択図】図3
