Definitions

  • the hub 1 has a circular shape when viewed projectively along the rotation axis RS of the turbofan 100, and as shown in FIG. 1, a substantially conical cone that rises in a mountain shape from the main plate 2 side toward the shroud 3 side. It is formed in a trapezoidal shape.
  • the shape of the hub 1 is not limited to the above shape, and may be another shape.
  • a rotation shaft such as a motor is connected to the hub 1.
  • the turbofan 100A according to the second embodiment is formed so that the upstream side flow path width W21 is larger than the upstream side flow path width W11, and the downstream side flow path width W22 is larger than the downstream side flow path width W12. It is formed to be small. That is, the turbofan 100A is formed so as to satisfy "upstream side flow path width W21> upstream side flow path width W11" and "downstream side flow path width W22 ⁇ downstream side flow path width W12".
