Abstract

The invention provides an air guide ring, used for air-conditioner outdoor unit, which includes side plate, top cover and axial-flow windwheel. Air-ducting ring includes: air-ducting ring body, which has the cavity of opening for upper and lower ends; multiple notches, which are arranged on the side wall of air-ducting ring body. And axial-flow windwheel is arranged in cavity, and side plate is arranged in the circumference of air-ducting ring body, and the upper port of side plate and air-ducting ring body are equipped with top cover. Air-ducting ring body, side plate and top cover define chamber jointly. The air guide ring provided by the invention, which has a plurality of slits formed on the side wall, forms a relatively closed cavity with the side plates around and the top cover, reducing the rotation noise of the axial flow fan by adopting the principle of resonance noise elimination of the perforated plate.

Description

technical field [0001] The invention relates to the field of air conditioning equipment, in particular to an air guiding ring, an outdoor unit of an air conditioner and an air conditioner. Background technique [0002] At present, commercial multi-connected systems mostly adopt the structure of large-diameter axial flow fans with top outlet. With the development of miniaturization and platformization of external units, the development trend of high-speed and large-diameter axial flow fans is obvious. Fan noise is mainly composed of rotating noise and eddy current noise, and the rotating noise is mainly low-frequency discrete noise, which is the main factor affecting the sound quality of the fan. As the rotational speed increases, the rotational noise dominated by low-frequency components grows more obviously than the eddy current noise, and this low-frequency "humming" abnormal sound is also more prominent. Contradictory to this is that with the increase in housing prices a...
