Abstract

본 발명은 축류팬(AXIAL FAN)에 관한 것으로 특히, 축류팬의 블레이드(BLADE) (5)와 블레이드 사이의 허브(HUB) (3) 표면에 허브의 축방향을 따라 수개의 홈(4)을 형성하여 허브 표면에서의 유체의 이동을 난류로 전환시키므로서 경계층의 두께(§1)를 감소시켜, 압력면(2)에서의 압력분포를 블레이드(5)와 허브(3)의 경계면까지 균일하게 분포시키므로 인해 축류팬의 압력을 상승시켜 효율을 증대시킨 축류팬의 구조에 관한 것이다.The present invention relates to an axial fan, and in particular, the grooves (4) along the axial direction of the hub on the surface of the blade (5) and the hub (HUB) between the blades of the axial fan (4) To reduce the thickness of the boundary layer (§1) by converting the flow of fluid on the hub surface into turbulent flow, so that the pressure distribution at the pressure surface 2 is evenly distributed to the interface between the blade 5 and the hub 3 The present invention relates to a structure of an axial fan that increases efficiency by increasing the pressure of the axial fan due to the distribution.
