| description | The utility model relates to the field of fan blades, in particular to an axial flow fan and an axial flow fan blade thereof. The axial flow fan blade comprises a hub and a plurality of axial flow blades regularly arranged on the outer side wall of the hub in the circumferential direction. A hub groove is formed in the shaft end of the side, facing the pressure face, of the hub, and a shaft sleeve used for being connected with a motor shaft is arranged in the center of the hub groove. The side wall of the hub groove is provided with heat dissipation holes penetrating through the side wall of the hub in the radial direction. When the axial flow fan blade rotates, heat near a crankshaft and a hub of the axial flow fan can be taken away, and a good heat dissipation effect is achieved.
本实用新型涉及风叶领域，尤其涉及一种轴流风机及其轴流风叶。轴流风叶，包括轮毂，以及沿周向规则布置于轮毂外侧壁上的多片轴流叶片；所述轮毂朝向压力面一侧的轴端上设有轮毂凹槽，轮毂凹槽的中心处设置有用于连接电机轴的轴套；所述轮毂凹槽的侧壁上设有径向贯通轮毂侧壁的散热孔。该轴流风叶旋转时可将机轴附近及轴流风机轮毂附近的热量带走，起到较好的散热效果。 |
