In some embodiments, the air conditioning case has a first opening and a second opening disposed opposite; the air outlet of the air outlet air duct is exposed through the first opening; and the air inlet of the air outlet air duct is exposed through the second opening.
The space surrounded by the heat dissipation air duct of the desktop air conditioner forms a heat dissipation air duct, and the heat dissipation air duct is a transmission channel of heat dissipation air flow. In the process of refrigerating or heating the desktop air conditioner, the heat dissipation airflow in the heat dissipation air duct is output outwards from the air outlet of the heat dissipation air duct.

That is to say, the installation manner of the two radiators in the desktop air conditioner provided by the embodiment of the present disclosure is no longer that the two radiators are arranged in parallel and extend in the same direction, but the two radiators are separately arranged and extend in different directions. Therefore, the desktop air conditioner changes the air flow temperature in the air outlet duct through the first radiator, and when the air flow temperature in the heat dissipation duct is changed through the second radiator, the air outlet direction of the air outlet duct is different from the air outlet direction of the heat dissipation duct, so that the mutual influence caused by the fact that the air outlet directions of the air outlet duct and the heat dissipation duct are the same can be reduced, and the air conditioning effect of the desktop air conditioner is improved.

In some embodiments, as shown in fig. 2, the second fins B are multiple, multiple second fins B are stacked, and a stacking direction of the multiple second fins B is the same as an extending direction of the outlet duct 102.
The plurality of second fins are stacked, gaps are formed between every two adjacent second fins in the plurality of second fins, and the second fins can heat or cool air in the gaps, so that the effect of adjusting the air outlet temperature in the radiating air duct is achieved.

In some embodiments, as shown in fig. 3 and 4, the air inlet of the heat dissipation air duct 102 is disposed at a side close to the air outlet duct 101;
the second fin B faces the air inlet of the air outlet duct 102, and is configured to block the air outlet of the air outlet duct 101 from entering the air outlet duct 102 from the air inlet of the air outlet duct 102.
The setting size of the second fin can be set with the air inlet area size in the air outlet direction of the air outlet duct in the heat dissipation air duct, for example, the setting size of the second fin can be greater than or equal to the air inlet area size, and the embodiment of the disclosure is not limited.
The second fins face the air inlet of the heat dissipation air duct. In the embodiment of the present disclosure, the extending direction of the second fin can be set to be parallel to the air outlet direction of the heat dissipation air duct.

the first heat sink 103 is located between the air inlet of the air outlet duct 101 and the first fan 105;
the second heat sink 104 is located between the first fan 105 and the second fan 106.
The first fan is used for outputting the air outlet flow passing through the first radiator to the outside of the air outlet duct, so that the air outlet duct can be used for outwards discharging air, and the air conditioning effect is achieved.
The second fan is used for outputting the heat dissipation air flow passing through the second radiator to the air outlet of the heat dissipation air duct, so that the heat dissipation air duct can outwardly exhaust air, and the heat dissipation effect is achieved.
In the embodiment of the disclosure, the air outlet direction of the first fan is the same as the air outlet direction of the air outlet duct; the air outlet direction of the second fan is the same as the air outlet direction of the heat dissipation air duct.
It should be noted that, the size of the first fan matches with the size of the air outlet cross section perpendicular to the air outlet direction of the air outlet duct. In the process of setting the size of the first fan, the size of the first fan can be set to be equal to the size of the air outlet section. Therefore, the air outlet area of the air outlet duct can be increased when the first fan is driven to rotate, and the air outlet effect of the air outlet duct is improved.
In a similar way, the size of the second fan is matched with the size of the heat dissipation section of the heat dissipation air duct, which is vertical to the air outlet direction. In the setting of the size of the second fan, the size of the second fan may be set to be equal to the heat dissipation sectional size. Therefore, the air outlet area of the heat dissipation air channel can be increased when the second fan is driven to rotate, and the air outlet effect of the heat dissipation air channel is improved.

In the embodiment of the present disclosure, the size of the first heat sink is positively correlated to the size of the first fan; the size of the second heat sink is positively correlated to the size of the second fan. When the size of the first heat sink is larger than that of the second heat sink, the size of the corresponding first fan may be set larger than that of the second fan.

That is to say, the air outlet flow passing through the first heat sink can be completely output to the outside of the air outlet duct through the first fan. So, can reduce the condition that the air-out wind current that passes through first radiator is detained in the air-out wind channel, improve the air-out effect in air-out wind channel.
The projection of the second radiator to the installation direction of the second fan covers the second fan. That is to say, the heat dissipation air flow passing through the second heat sink can be completely output to the outside of the air outlet of the heat dissipation air duct through the second fan. So, can reduce the condition that the heat dissipation wind current that passes through the second radiator is detained in the heat dissipation wind channel, improve the air-out effect in heat dissipation wind channel.

The semiconductor wafer is provided in plurality, and the plurality of semiconductor wafers are arranged in parallel and are cascaded with each other. In this way, the cooling or heating effect of the desktop air conditioner can be improved by arranging the plurality of semiconductor wafers.

When the desktop air conditioner is used for refrigerating, the cold end surface of the semiconductor wafer faces the first radiator, and the hot end surface of the semiconductor wafer faces the second radiator. At the moment, a first air flow entering from an air inlet of the air outlet air duct is changed into a cold air flow through a first radiator in the air outlet air duct, and the cold air flow is output outwards from an air outlet of the air outlet air duct through a first fan so as to achieve the aim of refrigeration; the second air flow entering from the air inlet of the heat dissipation air duct changes the heat of the heat-carrying end face of the second air flow passing through the second radiator in the heat dissipation air duct into the heat dissipation air flow, and the heat dissipation air flow is output outwards from the air outlet of the heat dissipation air duct through the second fan, so that the purpose of heat dissipation is achieved.
