Title (EN) PROPELLER FAN
(FR) VENTILATEUR HÉLICOÏDAL
(JA) プロペラファン
Abstract:
(EN) This propeller fan has a boss that rotates about an axial center and a plurality of blades disposed on the outer peripheral part of the boss. The blades have notches in the trailing edges thereof. The notches have three or more notched portions having triangular shapes in an overhead view, these notched portions being aligned from the inner peripheral ends of the blades toward the outer peripheral ends. The notched portions are configured such that the depths and widths thereof decrease after having increased from the inner peripheral ends of the blades toward the outer peripheral ends.
(FR) La présente invention concerne un ventilateur hélicoïdal ayant un bossage qui tourne autour d'un centre axial et une pluralité de pales disposées sur la partie périphérique externe du bossage. Les pales présentent des encoches dans leurs bords de fuite. Les encoches ont au moins trois parties entaillées ayant des formes triangulaires dans une vue d'au-dessus, ces parties entaillées étant alignées à partir des extrémités périphériques internes des pales vers les extrémités périphériques externes. Les parties entaillées sont configurées de telle sorte que les profondeurs et les largeurs de celles-ci diminuent après avoir augmenté des extrémités périphériques internes des pales vers les extrémités périphériques externes.
(JA) プロペラファンは、軸心を中心に回転するボスと、前記ボスの外周部に配設される複数枚の翼と、を有し、前記翼は、後縁に切欠を有し、前記切欠は、前記翼の内周端から外周端にかけて並べられた3個以上の上面視三角形状の切欠部分を有し、前記切欠部分は、深さ及び幅が前記翼の内周端から外周端にかけて一旦大きくなった後に小さくなるように構成されているものである。
