Abstract
저유량특성을 개선하기 위한 공기분리기를 구비한 축류팬 및 움직임날개 가변측류팬에 관한 것으로서, 공기 분리기를 갖는 축류팬의 소음저감과 고성능화를 도모하기 위해, 케이싱의 외주상에 고리형상으로 마련되어 움직임날개의 선단측의 흐름을 움직임날개의 상류로 인도하는 유로내에 구비한 정류날개를 구비한 공기 분리기에 있어서의 유로로의 입구부분의 정류날개의 안가장자리의 위치를 케이싱의 내직경위치보다 외직경측으로 후퇴시키고, 움직임날개로부터 유출기류와 정류날개의 간섭 및 움직임날개주위에 형성되는 압력장과 정류날개의 간섭을 완화하는 것으로 하였다.The present invention relates to an axial flow fan having an air separator for improving low flow characteristics and a variable side airflow fan having an air separator. In order to reduce the noise and improve the performance of the axial flow fan having the air separator, The position of the inner edge of the rectifying blade of the inlet portion to the flow path in the air separator provided with the rectifying vanes provided in the flow path for leading the flow of the leading end side of the vane to the upstream of the moving vane is set to the outside diameter So that the interference between the outflow airflow and the rectifying blade from the motion blades and the interference between the pressure field and the rectifying blades formed around the motion blades are alleviated.
이러한 것에 의해 공기분리기내에 발생하는 기류의 흐트러짐을 억제할 수 있어 공기분리기의 작동범위 확대 효과의 저하를 방지할 수 있다.This makes it possible to suppress the disturbance of the airflow generated in the air separator and to prevent the deterioration of the effect of increasing the operating range of the air separator.
