Referring to Fig. 4 and Fig. 5, Fig. 4 and Fig. 5 are schematic structural diagrams of Embodiment 2 of the present utility model. As shown in Fig. 4 and Fig. 5, the structure of the outdoor unit of the air conditioner in this embodiment is basically the same as that in Embodiment 1. The difference is that in the second embodiment, the outdoor unit heat exchanger 2 is located below the fan 3, and the air inlet 12 is arranged at the lower part of the front panel of the outdoor unit housing 1 (near the air outlet of the outdoor unit heat exchanger 2), The air outlet 13 is arranged on the upper part of the front panel of the outdoor unit casing 1 (near the air outlet of the fan 3 ). At this time, the outdoor heat exchanger 2 adopts a draft heat exchange method. Specifically, in this embodiment, there is no need to install the first partition plate 14 , and the fan 3 is slidably mounted on the inner top cover or the inner side wall of the outdoor unit housing 1 , near the front panel. The deflector 17 between the fan 3 and the outdoor heat exchanger 3 also guides the air entering the first storage chamber, so that the air flows in the first storage chamber in an orderly manner. Specifically, after entering the first accommodation chamber from the air inlet, the air passes through the outdoor heat exchanger 2 and flows along the channel between the rear end of the fan and the back plate of the outdoor unit casing 1 .

Specifically, refer to FIG. 6 , which is a schematic diagram of the air flow principle of the outdoor unit of the air conditioner in the second embodiment. As shown in FIG. 6 , the outdoor heat exchanger 2 adopts a suction-type heat exchange method, that is, the fan 3 continuously blows air out along the air outlet. The flow direction of the airflow in the first storage chamber is: after the air enters the first storage chamber along the air inlet, flows through the outdoor heat exchanger 2, flows out from the air outlet, and exchanges heat with the outdoor heat exchanger repeatedly. In the air suction heat exchange mode, during the operation of the fan 3, the air flows in a clockwise direction. Since the deflector is set between the fan 3 and the outdoor heat exchanger 2, the air entering from the air inlet 12 passes through the outdoor heat exchanger 2 and flows along the passage between the back plate of the outdoor unit housing 1 and the back of the fan 3. upward flow, thereby improving the circulation efficiency of the airflow in the first accommodation cavity.

It should be noted that, in the second embodiment, those skilled in the art can also arrange the fan 3 under the outdoor heat exchanger 2, and correspondingly exchange the positions of the air inlet and the air outlet. These all belong to the protection domain of the present utility model.
