As shown in connection with fig. 1-3, in some embodiments of the present application, the fan assembly 50 is disposed above the electronic control box assembly 40, and a portion of the exhaust passage is disposed above and below the electronic control box assembly 40, respectively.

Through setting up the passageway of airing exhaust in the below at automatically controlled box subassembly 40, can make the air current in the passageway of airing exhaust get into in the second heat dissipation passageway 412 through second air intake 451, improve the air current in the second heat dissipation passageway 412, through setting up the passageway of airing exhaust in the top at automatically controlled box subassembly 40, be convenient for guide the air current of airing exhaust of first heat dissipation passageway 411 and second heat dissipation passageway 412 to the passageway of airing exhaust in to discharge to the outside of box 10 through the passageway of airing exhaust, thereby accelerate the air current velocity in first heat dissipation passageway 411 and the second heat dissipation passageway 412, and then improve the radiating rate of automatically controlled board 42 and fin 43.

The foregoing is merely a preferred embodiment of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the technical scope of the present application should be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
