Abstract: The present disclosure provides a heat exchanger assembly and an air conditioner. The heat exchanger assembly comprises a first heat exchanger, a second heat exchanger and a third heat exchanger. The second heat exchanger is arranged to be angled relative to the first heat exchanger, the first end of the second heat exchanger is connected with or close to the first end of the first heat exchanger, and the second end of the second heat exchanger is away from the second end of the first heat exchanger. The third heat exchanger is arranged between the first heat exchanger and the second heat exchanger.

Abstract: The present application discloses a fin structure and a heat exchanger, wherein the fin structure includes: a fin base, the fin base having a tube hole for a heat exchange tube passing through, and the fin base being a corrugated fin; and a plurality of convex parts, the convex part being disposed on the fin base, and the plurality of convex parts surrounding an outer circumference of the tube hole. The fin structure and heat exchanger according to the present application can effectively improve a heat exchange effect of the fin and enhance a heat exchange performance of the heat exchanger.

Abstract: The present disclosure provides a centrifugal fan blade, an air treatment device and a fan; the centrifugal fan blade includes a hub and a plurality of fan blades; the plurality of fan blades are distributed around the periphery of the hub; each fan blade includes a first blade and a second blade; moreover, the first blade is in a backward blade form; and the second blade is in a forward blade form. The centrifugal fan blade can improve the flowing of the airflow and improve the air output efficiency.
