Abstract

The invention discloses an air conditioner and a cross flow fan thereof. The cross flow fan comprises volutes and an impeller; the volutes are arranged in multiple rows in the axial direction; and wind isolation devices are arranged in the intersections of two adjacent sections of the volutes. The wind isolation devices can isolate wind in the two adjacent sections of the volutes to inhibit axial flow movement in the two adjacent sections of the volutes, so that multiple exhaust ports of the cross flow fan are more uniform and stable in exhausting, the heat exchange is uniform, and the eddy current noise is greatly reduced.

Description

technical field [0001] The present invention relates to the technical field of refrigeration equipment, and more specifically, to an air conditioner and a cross-flow fan thereof. Background technique [0002] The cross-flow fan of the air conditioner includes a volute and an impeller. The volute is provided with a plurality of air outlets distributed in the axial direction, and the plurality of air outlets are arranged circumferentially in a staggered manner to realize multi-position and direction-changing air supply of the air conditioner. However, multiple air outlets are arranged in a staggered manner, and the position of the eccentric vortex will cause the internal airflow to move along the axial direction, resulting in uneven air outlets from multiple air outlets, uneven heat transfer, and large eddy current noise. [0003] To sum up, how to effectively solve the problem of uneven air output from multiple air outlets of the cross-flow fan is an urgent problem to be solv...
