The electric control box 100 is located on the airflow path of the outdoor fan, and the relative positions of the air inlet passage 11 and the air outlet passage 12 of the electric control box 100 are consistent with the airflow direction of the outdoor fan. In this way, as shown in Figure 6, a part of the airflow inhaled by the outdoor side air inlet can enter the electric control box 100 through the air inlet passage 11 to dissipate heat from the electric control box 100, and then discharge the electric control box 100 through the air outlet passage 12, and then Blow to the outdoor heat exchanger through the outdoor fan.

Further, the inner surface of the inner shell 14 is provided with a water-retaining structure 2, which is beneficial to prevent liquid from entering the electric control box 100 from the air inlet channel 11 or the air outlet channel 12, thus improving the heat dissipation performance of the box body 1. Water resistance of the bottom.

Wherein, as shown in FIG. 2 , the water retaining structure 2 includes structures such as a first water retaining plate 211 , water retaining ribs 212 , a second water retaining plate 214 , and water retaining side plates 22 . The first water baffle 211 is arranged opposite to the first port 111 of the air inlet channel 11, and the second water baffle 214 is arranged opposite to the second port 121 of the air outlet channel 12, for blocking the liquid entering the box body 1 from bottom to top . The water retaining ribs 212 can be vertically arranged with the first water retaining plate 211 to prevent the liquid entering the box body 1 from further flowing in the box body 1 in the horizontal direction or in other directions.

Further, as shown in FIG. 12 , the compressor 250 is arranged obliquely below the electric control box 100 . The heat exchange pipe 272 of the outdoor side heat exchanger of the window air conditioner 200 is connected to the subcooling pipe 280 . This is equivalent to extending the cooling medium cooling pipe 41 of the whole machine to form the supercooling pipe 280 after passing through the outdoor heat exchanger. The supercooling pipe 280 enters the water receiving tray 2122, passes through the water receiving tray 2122, extends upwards and is connected with the refrigerant heat dissipation pipe 41 of the refrigerant radiator 4 of the electric control box 100, and the refrigerant heat dissipation pipe 41 of the refrigerant radiator 4 is formed by After the box body 1 of the electric control box 100 is stretched out, it is connected to a throttle mechanism 290 such as a capillary tube, and then enters the indoor side heat exchanger 274, and the refrigerant radiating pipe 41 passing through the indoor side heat exchanger 274 is connected to the suction of the compressor 250. The air port forms a complete refrigerant cycle.

Taking refrigeration operation as an example, the high-temperature and high-pressure refrigerant of the compressor 250 is discharged from the exhaust port of the compressor 250, enters the outdoor side heat exchanger to condense and cool down, flows out, enters the supercooling pipe 280, and exchanges with the condensed water in the water receiving pan 2122 After heating, the temperature is further lowered, and then enters the electric control box 100 to cool the electric control box 100. After flowing out of the electric control box 100, it is further throttled and cooled by the throttling mechanism 290, and then enters the indoor side heat exchanger 274, and the indoor side heat exchanger After 274 evaporates and absorbs heat, it flows back to the compressor 250. Such an arrangement is not only conducive to improving the heat dissipation effect of the refrigerant radiator 4, but also beneficial to improving the cooling effect of the whole machine.
