저소음 축류형 소형홴의 개발

Tube axial fans were designed to provide effective cooling for a personal computer by using iDesignFan™ software. With basic input parameters of flow rate, pressure rise, rotating speed, and fan diameter, three dimensional geometry of blade is automatically generated and its performance and overall sound pressure level are predicted. In this steady, the newly developed fans of 60 ㎜ and 80 ㎜ diameters were proved to provide a very promising mode of low noise, compared with manufactured products.
