Embodiment Construction

[0029] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0030] Such as figure 1 with figure 2 As shown, the present invention provides an axial fan blade, including a hub 10 and a plurality of blades 30 arranged on the outer periphery of the hub 10, and the arc of each blade 30 projected along the radial section is formed by three continuous curves, The three continuous curves are the first curve S1 located at the innermost, the second curve S2 located in the middle, and the third curve S3 located at the outermost, wherein the first curve S1 and the third curve The curve S3 bends toward the suction surface C, and the second curve S2 bends toward the pressure surface D. It can be seen from the figure that the curve S1 of the first segment and the curve S3 of the third segment bend convexly toward the s...

Abstract

The invention provides an axial-flow fan blade which comprises a wheel hub and a plurality of blade bodies arranged on the periphery of the wheel hub. An arc line of the section projection of the blades along a radial direction is formed by three sections of continuous curves which are respectively the first section of curve placed on the innermost side, the second section of curve placed in the middle and the third section of curve placed on the outermost side. The first section of curve and the third section of curve are bent towards a suction surface, and the second section of curve is bent towards a pressure surface. A chord line of the projection faces of the blade bodies of the axial-flow fan blade along the radial direction changes according to a certain law, on the premise that air amount and noise of a fan are guaranteed, production cost and mounting space are saved, and power consumption is lowered.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular, to an axial flow fan blade. Background technique [0002] The axial flow fan blade is installed and fixed on the air duct outside the air conditioner through the shaft hole in the middle of the hub and the motor shaft. The quality of its design is the main determinant of the air duct of the outdoor unit. [0003] Existing air-conditioning products tend to be lighter and thinner, which makes the structure of the air duct more compact, and the installation space of the fan becomes smaller, but this brings about the deterioration of the noise, which puts forward more challenges for the design of the airfoil of the axial flow fan blade and other structures. high demands. Contents of the invention [0004] The purpose of the present invention is to provide an axial-flow fan blade to solve the technical problems that the airfoil of the existing axial-flow fan blade ca...
