Definitions

  • FIG. 1 illustrates a perspective view of a fan in accordance with a first preferred embodiment of the present invention
  • FIG. 2 illustrates a diagram of a partition line in a fan of the present invention
  • the radius of curvature of the top end 3b of the blade 3 is different from the radius of curvature of the bottom end 3 a, for smooth flow of air, and, particularly, it is preferable that the radius of curvature of the bottom end 3 a is greater than the radius of curvature of the top end 3b.
  • FIG. 4 illustrates a front view of the fan in FIG. 1. Referring to FIG. 4, an angle a side edge 3e of one of the blades forms is formed such that the angle becomes the greater as it goes from the bottom of the hub 2 to the top of the hub 2 for improvement of flow characteristics.
  • the blade 3 is formed
  • this fan structure enables to increase areas of the blades 53 while keeping a rotation locus of the blades 53 the same, an air flow rate of the fan is increased.
  • the blades do not overlap with each other when seen from the direction of the rotation shaft 51.
