Abstract: front page image
(EN)Provided is an axial flow blower wherein noise is reduced by ensuring the effective work of blades and suppressing the blade tip vortex. The axial flow blower is formed so that a chord center line (37) extending so as to connect chord center points (34) from the inner peripheral end to the outer peripheral end of a blade (3), is curved and projected toward the downstream side in the entire region.
(FR)Cette invention concerne un ventilateur axial dans lequel le bruit est réduit en assurant le fonctionnement efficace des pales et en supprimant le tourbillon d'extrémité de pale. Le ventilateur axial est formé de manière à ce qu'un axe de corde (37) s'étendant de façon à relier des points centraux de corde (34) de l'extrémité périphérique interne à l'extrémité périphérique externe d'une pale (3), soit incurvé et projeté vers le côté aval dans la région tout entière.
(JA) 翼の有効仕事の確保及び翼端渦の抑制によって低騒音化を図るようにした軸流送風機を提供する。 本発明の軸流送風機は、翼3が、翼3の内周端から外周端までの翼弦中心点34を結んだ翼弦中心線37が全領域で下流側に凸状の曲線となるように形成されている。
