In addition, since all the water entering the fin gap 32 falls down by gravity, all the water entering the fin gap 32 flows over the surface of the heat dissipating fin, increasing the heat dissipating efficiency of the heat dissipating fin 31.

In this embodiment, the outdoor unit of the air conditioner further includes a water receiving tray 4 disposed below the heat exchange condenser 3, a water supply pipe 21 communicating with the spray device 2, and a water return pipe 22 connecting the water receiving tray 4 and the water supply pipe 21.
