Practical Study on Optimal Design of Axial-flow Fan

축류팬의 실용적 최적 설계에 대한 연구

Small-sized fans for cooling electronic components are usually produced by injection molding in unified form including blade and hub. However, in case of middle and large-sized fans, they deal ill various products with varied numbers of blade or stagger angles after designing a single blade by molding or aluminum die casting. At this occasion, it is necessary to study design method for high-performance axial fans can be operated with various numbers of blades or stagger angle using unique blade for specified conditions. Therefore, the goal in this study is developing a optimal design method which improves performance of axial fans within the large range of operating by single blade.
