Abstract

본 발명은 씨로코팬에 관한 것으로, 내경과 외경의 사이에 일정 간격을 두고 형성되는 블레이드 곡선을 각각 다른 원의 중심과, 각각 다른 반경을 갖는 이중 원호로 형성하여, 종래의 에어포일형 블레이드 곡선이 표현하는 최대 캠버전을 가지면서 에어포일형 블레이드 곡선 보다는 간단한 이중 원호로 블레이드 곡선을 구성할 수 있으므로, 설계 작업을 보다 용이하게 하는 동시에 가공성을 향상시킴으로써 씨로코팬의 제조를 위한 생산성 향상에 크게 기여하며, 또한 고풍량 씨로코팬의 제조를 가능하도록 한 것이다.The present invention relates to a sirocco fan, wherein a blade curve formed at regular intervals between an inner diameter and an outer diameter is formed by a double arc having a center and a radius different from each other. Since the blade curve can be configured by a simple double arc rather than an airfoil blade curve while having the maximum cam version to be expressed, it greatly improves the productivity for the manufacture of the sirocco fan by making the design work easier and improving the workability. In addition, it is possible to manufacture a high air flow sirocco fan.
