And the arrangement of the radiating fins 422 can not block the flow of the air flow in the horizontal direction, so that the arrangement of the electric control box 4 is prevented from influencing the flow speed and flow rate of the air flow passing through the outdoor heat exchanger 2, and the heat exchange effect of the outdoor heat exchanger 2 is ensured.

Referring to fig. 16, the electronic control main body 41 includes a housing 411 and an electronic control board 412, the electronic control board 412 is vertically disposed in the housing 411 to reduce the overall volume of the electronic control box 4, the housing 411 protects the electronic control board 412 outside the electronic control board 412, at least a portion of the radiator 42 is disposed in the housing 411 so that the radiator 42 is connected with the electronic control board 412 to achieve better heat dissipation, at least a portion of the radiator 42 is disposed outside the housing 411 and is located at a side of the electronic control board 412 facing the first air inlet area 1111 to ensure that the radiator 42 can be in direct contact with the air flow, avoid the air flow from being blocked by the housing 411, and ensure that the radiator 42 can be in contact with the air flow that first enters the installation cavity 10 to ensure the heat dissipation effect of the radiator 42.
