Abstract

The invention relates to a swirl eliminator, a mixed flow fan and an air conditioner. The swirl eliminator comprises a wheel cover (10), a hub (20) and blades, wherein the wheel cover (10) is providedwith a through cavity, the hub (20) is arranged in the cavity, a flow channel (50) is formed between the hub (20) and the cavity wall of the cavity, the blades are arranged in the flow channel (50) and used for guiding airflow flowing through the flow channel (50) to flow out in the direction close to the axis (60) of the swirl eliminator, a central trajectory (53) on a longitudinal section, passing through the axis (60) of the swirl eliminator, of the flow channel (50) comprises a first trajectory and a second trajectory, the distance between the first trajectory and the axis (60) of the swirl eliminator increases in the airflow flowing direction, the second trajectory is located downstream of the first trajectory, and the distance between the second trajectory and the axis (60) of the swirl eliminator decreases in the airflow flowing direction. The swirl eliminator can improve the air supply performance and improve the air outlet pressure head.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to a racemizer, a mixed-flow fan and an air conditioner. Background technique [0002] In order to improve the quality and comfort of air conditioners, it is necessary to match suitable fans for different needs and models. Under the premise of meeting the air volume and noise requirements, in order to achieve anti-high static pressure air supply, mixed flow fans are often used for air conditioning air supply. [0003] However, the mixed-flow fan itself has an inclined air outlet, and the air supply is not concentrated, which seriously affects the wind speed distribution and heat exchange performance on the surface of the heat exchanger inside the air conditioner, and the required aerodynamic performance cannot be achieved by optimizing the mixed-flow fan alone. [0004] It should be noted that the information disclosed in the Background of the Invention section is only intended to inc...
