Embodiment 1

[0028] Example 1, please refer to Figure 1-Figure 5 As shown, this embodiment provides an axial fan blade, including: a hub 1 and several blades 2 arranged on the hub 1 along the circumferential direction, each blade 2 has a leading edge 21, an outer edge 22 and a tail connected in sequence. The straight line formed by the two ends of the edge 23 and the outer edge 22 is the first straight line, and the angle between the first straight line and the first plane is α, wherein, the first plane is perpendicular to the axis of the hub 1, and 20°≤α≤35 °.

[0029] In this embodiment, the axial-flow fan blade obtained through the above-mentioned design, by optimizing the structure of the blade 2, the angle between the straight line formed by the two ends of the outer edge 22 and the plane perpendicular to the axis of the hub 1 is α, and 20° ≤α≤35°. Therefore, the air outlet effect of the air supply airflow generated by the axial flow blades is more stable, and the problem of radial...

Abstract

The invention provides an axial flow fan blade and an axial flow fan, and relates to the technical field of fans. The axial flow fan blade comprises a hub and a plurality of blade bodies arranged on the hub in the circumferential direction. Each blade is provided with a front edge, an outer edge and a tail edge which are sequentially connected, wherein a straight line formed by two end points of the outer edge serves as a first straight line, the included angle formed between the first straight line and a first plane is alpha, the first plane is perpendicular to the axis of the hub, and alphais larger than or equal to 20 degrees and smaller than or equal to 35 degrees. According to the axial flow fan blade, the structure of the blade bodies is optimized, so that the included angle betweenthe straight line formed by the two end points of the outer edge and the plane perpendicular to the axis of the hub is alpha, and alpha is larger than or equal to 20 degrees and smaller than or equalto 35 degrees. Therefore, the air blowing effect of the supply air flow generated by the axial flow fan blade is more stable, and the problem of radial diffusion is not likely to occur is solved.

Description

technical field [0001] The invention relates to the field of fans, in particular to an axial flow fan blade and an axial flow fan. Background technique [0002] Axial flow fan blade is a kind of fan blade widely used in air conditioners, fans and other equipment, which can play the role of circulating air flow and improving heat dissipation. The axial-flow fan blades are driven and rotated by a motor to generate air supply airflow, but the air supply airflow generated by the existing axial-flow fan blades has the problem of unstable air outlet effect and prone to radial diffusion. Contents of the invention [0003] The present invention provides an axial flow fan blade and an axial flow fan, aiming at improving the problem of unstable blowing effect of the air supply air generated by the existing axial flow fan blades. [0004] The present invention is achieved like this: [0005] An axial-flow fan blade, comprising: a hub and a plurality of blades arranged on the hub al...
