Fan, Molding Die, and Fluid Feeder |
摘要 |
In the present invention, a through-flow fan is formed of a resin. The through-flow fan is provided with: a plurality of fan blades (21) on which are formed vane surfaces (23) comprising a positive-pressure surface (24) and a negative-pressure surface (25); and a perimeter frame (13) that is provided to a base section (31) of the fan blades (21) and connects the plurality of fan blades (21) to each other. The fan blades (21) have a vane cross-sectional shape in which a plurality of recesses are formed on the positive-pressure surface (24) and/or the negative-pressure surface (25) thereof. The fan blades (21) are formed so that the surface area of the vane cross-section decreases going from the base section (31) of the fan blades (21) toward a distal end (32) thereof. The fan blades (21) are formed to be thicker at protrusions on the base section (31) side. Such a configuration provides a fan, molding die, and fluid feeder device offering excellent resin molding performance. |
