When the condensing unit 200 is installed in the second condensing passage 150, the bottom plate 220 is disposed close to the fixing frame 160, and the heat-dissipating fins 210 are disposed away from the fixing frame 160. The installation wall 170 limits the relative position of the condensing unit 200, prevents the condensing unit 200 from shifting, ensures that the projections of the first condensing channel 140 and the second condensing channel 150 on the inner wall of the shell 100 are at least partially overlapped while ensuring the condensing effect, and improves the condensing efficiency.
