説明
Small fans are especially used in information device for its cooling. Since packaging density has been increasing, requirements of not only performance improvement but also noise reduction arise strongly. An experimental research on small multi-blade fan was carried out in order to improve performance and reduce noise. In this report, effects of scroll angle, tongue clearance and inlet diameter on small multi-blade fan with impeller diameter of 100 mm were investigated. The optimal index efficiency and noise were found by making a scroll starting point radius and a scrool termination radius into a design index, instead of the scrool design by a conventional clearance and a scroll angle. In order to reduce noise, we found that we should set the radius of scroll beginning into about 0.65 times of the outlet diameter of the impeller. And for improving efficiency, we should set the radius of scroll end into about 0.9 times of the outlet diameter of the impeller.
