[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

The invention discloses an axial flow wind wheel and an air conditioner with the same. The axial flow wind wheel includes a hub and a plurality of blades, and the plurality of blades are distributed at intervals along the circumferential direction of the hub. Each blade is connected to the hub and is close to the outer edge of the blade There are multiple groups of hole groups arranged at the position of the hub, and the multiple groups of hole groups are arranged at intervals along the radial direction of the hub, and each group of hole groups includes a plurality of spaced apart through holes, and the plurality of through holes are arranged along the circumferential direction of the hub . According to the axial flow wind wheel of the present invention, by setting multiple groups of hole groups at the outer edge of the blade, part of the airflow on the pressure surface of the blade can directly flow to the suction surface through the hole groups, thereby reducing the flow from the outer edge of the pressure surface of the blade to the suction force. In order to reduce the leakage vortex generated on the outer edge of the suction surface, the vortex noise of the axial flow wind turbine can be reduced. In addition, the setting of the hole group can also reduce the weight of the blade, thereby reducing the leading edge resistance of the blade. In turn, the motor power of the 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...
