The first fan 21 is disposed corresponding to the air inlet 102 to drive air to enter the containing space 101 of the scroll casing 10 through the air inlet 102 and to be discharged through the air outlet 103, so as to drive the air to flow, and thus the air conditioner 100 can blow cool air or blow hot air for heating. For example, in some embodiments, the first fan 21 is operable to drive air flow such that the air flows through the first heat exchanger structure 51 to exchange heat with the first heat exchanger structure 51 to obtain cool or hot air.

In other words, both the airflow flowing through the heat dissipation member 32 and the external natural air can enter the heat dissipation space 104, so as to reduce the temperature of the airflow in the heat dissipation space 104 and improve the heat dissipation effect.

The heat radiation hole 105 and the air intake opening 102 are located on the same side of the first fan 21 in a direction parallel to the rotational axis of the first fan 21 (e.g., the left-right direction shown in fig. 7). So that the distance between the heat dissipation holes 105 and the air inlet 102 is closer, and the air in the heat dissipation space 104 can flow into the containing space 101 from the air inlet 102 more quickly after flowing out through the heat dissipation holes 105, so as to improve the effect of driving the air flow in the heat dissipation space 104 and improve the heat dissipation efficiency; and the air can flow into the holding space 101 from the axial end of the first fan 21, the air enters the first fan 21 from the air inlet 102 without changing the wind direction, the wind resistance is smaller, and the air inlet is smoother.

For example, the left side wall of the volute 10 projects to the left, or the right side wall of the volute 10 projects to the right. Therefore, the distance between the side wall of the volute 10 and the radiating piece 32 can be increased, damage caused by overhigh temperature of the volute 10 due to heat of the radiating piece 32 is prevented, the air flow rate between the radiating piece 32 and the side wall of the volute 10 can be ensured, the radiating hole 105 is prevented from being blocked by the radiating piece 32, the wind resistance is reduced, and the radiating efficiency is improved.

As shown in fig. 8-10, the peripheral wall of the heat dissipation space 104 may be provided with a plurality of heat dissipation holes 105 arranged at intervals to further increase the air flow rate and improve the heat dissipation efficiency. For example, in the embodiment including the protruding portions 12, a plurality of heat dissipation holes 105 may be provided at intervals on each protruding portion 12.

According to some embodiments of the present invention, as shown in fig. 6 and 7, the first fan 21 is a dual centrifugal fan, two opposite sidewalls of the spiral case 10 may be respectively provided with the air inlets 102, and the two air inlets 102 respectively correspond to two wind wheels of the dual centrifugal fan, for example, the two air inlets 102 may be respectively located at two sides of the dual centrifugal fan along the axial direction of rotation.

In addition, in the embodiment including the protruding portion 12, as shown in fig. 9, the protruding portion 12 and the motor bracket 40 may be located on the same side of the scroll casing 10, so that after the air flows out from the heat dissipation holes 105 on the protruding portion 12 in the direction of the rotation axis of the first fan 21, the air is less obstructed by the fan bracket in the process of flowing to the air inlet 102, and the air can flow into the containing space 101 from a larger range of the air inlet 102.

For example, in the example shown in fig. 9, the motor bracket 40 includes three arms that divide the intake vent 102 into three intake regions, and the heat dissipation hole 105 is disposed adjacent to one of the intake regions. The arm is higher than the plane of the air inlet 102 by a certain height, and the protrusion 12 is arranged to enable the heat dissipation hole 105 to be higher than the plane of the air inlet 102 by a certain height, so that the air flowing out from the heat dissipation hole 105 can smoothly cross the arm to flow to the other two air inlet areas, and can flow into the containing space 101 from the three air inlet areas more quickly.

In some embodiments, as shown in fig. 5 and 6, the first fan 21 is a dual centrifugal fan, two opposite sidewalls of the scroll casing 10 may be respectively provided with the air inlets 102, and each air inlet 102 may be correspondingly provided with the first heat exchanger structure 51, so that after passing through the first heat exchanger structure 51, the air can directly enter the containing space 101 through the air inlets 102, so that the air can perform sufficient heat exchange with the first heat exchanger structure 51.
