Among them, the first heat exchanger 106 and the second heat exchanger 206 are both integrated arc heat exchangers with a large heat exchange area. Compared with the arc structure formed by the multi-stage structure, the integral arc structure is convenient It is installed in the shell and occupies less internal space.

Since the assembly relationship between the first heat exchanger 106 and the first air conditioner body 100 is the same as the assembly relationship between the second heat exchanger 206 and the second air conditioner body 200, only the first heat exchanger 106 and the first air conditioner body are used in this embodiment. The assembly of 100 will be described as an example, and the assembly of the second heat exchanger 206 and the second air conditioner body 200 will not be repeated.

A cavity D is formed between the second heat exchange part 1062 and the first air duct 105, and the cavity D is configured such that when the first cross-flow fan 104 rotates, a negative pressure area D is formed in the cavity so that the air from the first air inlet 102 flows through The second heat exchange part 1062 . Due to the existence of the negative pressure cavity D, the air volume of the first air inlet 102 flowing through the second heat exchange part 1062 can be greatly increased, so that the air at the first air inlet 102 can evenly flow through the first heat exchange part 1061 and the second heat exchange part 1062 improve the utilization rate of the second heat exchange part 1062 and improve the overall heat exchange efficiency of the heat exchanger.
