Therefore, the water retaining body 21 can effectively prevent liquid from entering the accommodating space 13 through the air outlet channel 12 to cause negative effects on the heating elements 52 such as electronic components in the accommodating space 13, and the use safety of the heating elements 52 such as electronic components in the accommodating space 13 is improved.

The electric control box 100 is located on the airflow path of the outdoor fan, and the relative positions of the air inlet channel 11 and the air outlet channel 12 of the electric control box 100 are consistent with the airflow direction of the outdoor fan. Thus, as shown in fig. 6, a part of the airflow sucked from the outdoor side air inlet can enter the electronic control box 100 through the air inlet channel 11 to dissipate heat of the electronic control box 100, and then is discharged from the electronic control box 100 through the air outlet channel 12, and is blown to the outdoor side heat exchanger by the outdoor side fan.

Further, the inner surface of the inner casing 14 is provided with the water retaining structure 2, which is beneficial to preventing liquid from entering the electric control box 100 from the air inlet channel 11 or the air outlet channel 12, thereby improving the water resistance of the bottom of the box body 1 on the basis of considering the heat dissipation performance.

As shown in fig. 2, the water retaining structure 2 includes a first water retaining plate 211, a water retaining rib 212, a second water retaining plate 214, a water retaining side plate 22, and the like.
