Problems solved by technology

[0002] In related technologies, most of the air conditioners use axial-flow wind rotors for heat dissipation. The axial-flow wind rotors include two or more blades arranged on the hub. Distributed on the hub, when the axial flow wind turbine with conventional blade structure rotates, it is easy to cause the accumulation of low-energy fluid on the suction surface of the blade, and form a large vortex on the suction surface of the blade, resulting in a higher wind turbine during operation. aerodynamic noise

Abstract

The invention provides an axial flow wind wheel and an air conditioner with the same. The axial flow wind wheel comprises a hub and a plurality of blades distributed in the circumferential direction of the hub in a spaced manner; each blade is connected with the hub; the position close to the outer edge of each blade is provided with multiple hole groups, which are distributed in the radial direction of the hub in a spaced manner; each hole group comprises a plurality of mutually-spaced through holes; the through holes are arranged in the circumferential direction of the hub. The axial flow wind wheel has the advantages that the outer edge positions of the blades are provided with the multiple hole groups, so that part of air flow of a pressure surface of each blade can flow to a suction surface via the hole groups directly, air flow flowing from the outer edge of the pressure surface of each blade to the suction surface is reduced, leaking vortexes generated at the outer edges of the suction surfaces can be reduced and eddy current noise of the axial flow wind wheel can be reduced; with the hole groups, the weight of the blades can be reduced, so that the front edge resistance of the blades can be reduced and the motor power of an air conditioner can be reduced.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to an axial flow wind wheel and an air conditioner with the same. Background technique [0002] In related technologies, most of the air conditioners use axial-flow wind rotors for heat dissipation. The axial-flow wind rotors include two or more blades arranged on the hub. Distributed on the hub, when the axial flow wind turbine with conventional blade structure rotates, it is easy to cause the accumulation of low-energy fluid on the suction surface of the blade, and form a large vortex on the suction surface of the blade, resulting in a higher wind turbine during operation. Aerodynamic noise. According to experimental analysis, 50%-70% of the noise of the air conditioner is caused by the aerodynamic noise of the axial flow wind wheel. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art to a certain extent...
