Fan device with blades with selectable inclination |
摘要 |
Provided herein a fan device with blades with selectable inclination designed to vary the inclination of the blades as the operating temperature varies and comprising: an airscrew (3), including a rotation shaft (5) and a plurality of blades (6) with a degree of rotational freedom in a radial direction (6a); a supporting structure (2), designed to support at least the airscrew (3); an adjustment rod (10) connected to the blades (6) in a way, designed to link its own axial rotation to the rotation of the blades (6) with respect to said degree of freedom (6a); and a sensor and actuator assembly (4) including an actuator element (12) made of shape-memory material, designed to vary the axial angular position of the adjustment rod (10) as the operating temperature varies.
