Claim 0:
1. An air duct component for a cross-flow impeller comprising:
a first volute member, an inner end of the first volute member including a volute tongue; and
a second volute member;
wherein:
the first volute member and the second volute member are arranged opposite to each other in a cross section perpendicular to an axis of the cross-flow impeller;
a cross-flow air duct formed between the first volute member and the second volute member includes a middle air duct section and an end air duct section arranged along an axial direction of the cross-flow impeller, the end air duct section being located at an end of the middle air duct section;
the middle air duct section includes a middle air outlet duct located downstream of a vertical line that passes through the volute tongue and is perpendicular to the second volute member;
the end air duct section includes an end air outlet duct located downstream of the vertical line; and
an area of a cross-section of the middle air outlet duct perpendicular to the axial direction of the cross-flow impeller is larger than an area of a cross-section of the end air outlet duct perpendicular to the axial direction of the cross-flow impeller.
