摘要： The present invention relates to an axial flow fan which prevents the deformation of blades even when rotated at high speed, thus promoting the structural stability. The axial flow fan includes a hub and a plurality of blades, which are arranged along a circumferential outer surface of the hub in a radial direction such that the direction of a sweeping angle of each of the blades alternately changes between a blade root and a blade tip. A chord length, which is the length from a leading edge to a trailing edge of the blade, gradually reduces from the blade root to an intermediate portion of the blade, while the chord length gradually increases from a predetermined position on the intermediate portion of the blade to the blade tip.

摘要： Disclosed is an axial flow fan capable of achieving reduction of noise while having a high blowing efficiency compared to the power consumption of a motor adapted to drive the axial flow fan. The axial flow fan includes a hub, and a plurality of blades extending radially around the hub. Each blade has a sweep angle varying gradually from a backward angle at a root of the blade connected to the hub to a forward angle at a tip of the blade, while having a flow dispersion region having a plurality of regions where the sweep angle is alternately changed, at a region defined between a backward sweep angle region at the root of the blade and a forward sweep angle region at the tip of the blade. Each blade has a longitudinal cross section curved to have a wave structure between the root of the blade and the tip of the blade. The axial flow fan may further include a fan band connecting tips of the blades. The axial flow fan achieves reduction of blowing noise by receiving air in a dispersed state at the leading edge of each blade, discharging air in a dispersed state at the trailing edge of each blade, and offsetting turbulent flows of air by virtue of the wave-shaped longitudinal cross-sectional structure of each blade.

摘要： Blades mounted on a circumferential outer surface of a hub of an axial flow fan do not deform even when rotated at high speed, thus promoting structural stability. The direction of the sweeping angle of each blade alternately changes between the blade root and tip. A chord length between the blade leading and trailing edges gradually decreases from the blade root to an intermediate portion of the blade, and the chord length gradually increases from a predetermined position on the intermediate portion of the blade to the blade tip.

摘要： An airflow guide stator vane for an axial flow fan and a shrouded axial flow fan assembly having such stator vanes are disclosed. The airflow guide stator vane has a leading edge line, a trailing edge line, and an airflow guide surface extending from the leading edge line to the trailing edge line. The stator vane is radially positioned in an axial flow fan and is curved so that its leading edge line is perpendicular to oblique velocity components of an airflow each of which is a sum vector of a rotation-directional velocity component and a radius-directional component of an air particle of the airflow. The axial flow fan assembly comprises an axial flow fan and a shroud. The axial flow fan consists of a circular central hub connected with a driving shaft of a motor and a plurality of blades radially arranged along the circumference of the hub. The shroud consists of a housing surrounding the peripheral ends of said axial flow fan and forming an airflow passage, a motor support being positioned at its center portion and holding a motor for driving said axial flow fan, and the above-described stator vanes.
