Abstract
Description
Claims (6)
- 허브의 외둘레에 복수개의 블레이드가 형성된 축류팬에 있어서,상기 블레이드에는 유동되는 공기의 압력이 작용되는 압력면과 부압이 작용되는 부압면 사이에 압력차를 감소시키기 위하여 압력면 측으로 돌출된 융기부가 형성된 것을 특징으로 하는 축류팬.
- 제 1 항에 있어서,상기 블레이드는 일정 크기의 레이크각을 가지도록 형성된 것을 특징으로 하는 축류팬.
- 제 1 항에 있어서,상기 융기부는 상기 블레이드의 팁 측에 형성된 것을 특징으로 하는 축류팬.
- 제 3 항에 있어서,상기 융기부는 상기 블레이드의 허브와 팁 사이 거리의 0.3 내지 1 위치 사이에 형성된 것을 특징으로 하는 축류팬.
- 제 4 항에 있어서,상기 융기부는 2차 함수로 표현되는 곡면 형상인 것을 특징으로 하는 축류팬.
- 제 5 항에 있어서,상기 융기부는 선단과 후단이 동일 직선상에 위치되는 것을 특징으로 하는 축류팬.
