INCREASED PRESSURE AIR STREAM GUIDE DEVICE FOR FAN

摘要

PROBLEM TO BE SOLVED: To provide an increased pressure air stream guide device for a fan capable of intensifying air pressure outputted by the fan by forming the guide of a tangential line speed component of air stream so as to reduce windage caused by a rib by the maximum extent and guiding and operating it efficiently. SOLUTION: An increased pressure air stream guide device for a fan which supports a movable blade and increases air pressure generated when the movable blade rotates is provided with an outer frame 301, a support part 304 supporting the movable blade, and an air stream guide part 202 increasing air pressure generated when the movable blade rotates by connecting it between the outer frame 301 and the support part 304.
