Embodiment Construction

[0017] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0018] Such as Figure 1-Figure 4 As shown, the present invention provides a double-duct wind wheel, including inner blades 3, outer blades 1, wind-inducing ring 2 and hub 4, the wind-inducing ring 2 is sleeved on the outside of the hub 4, and the inner blades The inner and outer ends of 3 are fixedly connected with the inner side of the wind-inducing ring 2 and the outer side of the hub 4 respectively, and the inner end of the outer blade 1 is fixedly connected with the outer side of the wind-inducing ring 2 . In this way, the inner blade 3 and the outer blade 1 are arranged outside the hub 4, and the contact area between the blade and the air is increased through the inner blade 3 and the outer blade 1. When the i...

Abstract

The invention relates to the field of air conditioning, and in particular to a wind wheel with double air ducts. The wind wheel comprises an inner blade, an outer blade, an air guide ring and a wheel hub, the air guide ring is sleeved on the outer side of the wheel hub, both ends of the inner blade are fixedly connected with the inner side of the air guide ring and the outer side of the wheel hub, and one end of the outer blade is fixedly connected with the outer side of the air guide ring. The contact area of the blades with air is increased by the inner blade and the outer blade; when the inner blade and the outer blade rotate, the inner blade rotates to drive a part of air to flow toward the front of the inner blade, and the outer blade rotates to drive a part of air to flow toward the front of the outer blade so as to increase the input air; moreover, the inner blade is arranged at the middle of the outer blade, the inner blade blows air at the same time, and the outer blade generates no eddy at the position of the inner blade in the rotation process, thereby effectively avoiding the generation of noise; and compared with the prior art, the wind wheel with double air ducts provided by the invention has the advantages of simple structure, low manufacturing cost, large air volume and low noise.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a double-duct wind wheel. Background technique [0002] At present, most of the existing air-conditioning outdoor units use axial-flow wind rotors for heat dissipation. The axial-flow wind rotors include two or more blades arranged on the hub. The spacing is distributed on the hub. When an axial-flow wind turbine with a conventional blade structure rotates, it is easy to cause low-energy fluid to accumulate on the suction surface of the blade, and a large-sized vortex is formed 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 outdoor unit is caused by the aerodynamic noise of the axial flow wind wheel; and the air supply volume is relatively small. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide...
