| 摘要 |
The present invention relates to a cooling/heating air flow diffusing fan and, more particularly, to a cooling/heating air flow diffusing fan comprising: a rotating bundle (120) fixed to a cooling/heating device (200) installed on a ceiling; and blades (160) radially formed on the rotating bundle (120) so as to pivot using the rotating bundle (120) as a shaft, wherein the blades (160) have the shape of plates, the blades (160) are installed to slope such that, on a horizontal plane, front parts thereof, which face in the direction of pivoting, are closer to the cooling/heating device, the blades (160) have bent portions (166) formed on rear parts thereof along the longitudinal direction, and the blades (160) accordingly pivot, using the rotating bundle (120) as a shaft, by means of a cooling/heating air flow discharged from the cooling/heating device (200) and diffuses the cooling/heating air flow, thereby improving the cooling or heating efficiency. |
