Example 6
Preferably, the present embodiment provides a condenser air duct device, as shown in fig. 7, which is different from embodiment 6 in that: the condenser 15 is located at the air duct downstream of the first fan 12. The specific design is as follows:

Further, the condenser 15 is disposed obliquely inside the first housing; wherein the inclination θ of the condenser 15 is 10-90 ° the condenser 15 has a first end and a second end disposed opposite each other; wherein the first end of the condenser 15 is close to the top of the first shell and is arranged towards the first air port 112; the second end of the condenser 15 is arranged near the bottom of the first housing; when the first casing of the condenser air duct device includes a side portion, and the air outlet 111 is formed in the side portion, the second end of the condenser 115 is disposed towards the air outlet 111 (when the plurality of condensers 15 are disposed, the plurality of condensers 15 are disposed obliquely and dispersedly).

According to the condenser air duct device provided by the embodiment, the condenser 15 is arranged at the position of the downstream air duct of the first fan 12, so that the wind speed distribution passing through the condenser is uneven, the heat exchange effect of the system is poor, and the thickness of the whole machine can be reduced.

In addition, considering that the top cover 133 increases wind resistance to reduce the wind quantity, the rotation speed of the fan can be properly increased to compensate, so that the heat exchange quantity of the system is ensured. As shown in fig. 6, when the condenser air duct device provided in the above embodiment is used in normal weather, the top cover 133 is moved to the second position, and at this time, the top cover 133 does not cover the first air port 112, so that the first air port 112 is directly exposed, and thus the air flow directly enters the first housing through the first air port 112, and is discharged through the air outlet 111 after heat exchange of the condenser, so that the ventilation of the condenser air duct device is smoother, and the wind resistance is reduced, thereby ensuring the energy efficiency.
