In this way, the air of the air duct machine can be blown into the first air duct section 20 and the communicated second air duct section 30. Because the second air duct section 30 has the air duct air outlet 31, and the air duct air outlet 31 is arranged on the same side as the air inlet 101 of the casing 100 and adjacent to the air inlet, the air inlet position and the air outlet position of the air duct machine are on one side, and the air inlet and outlet structure of the traditional air duct machine is changed. Therefore, slotting or perforating at a plurality of positions in different directions is not needed, and the limitation of the installation condition of the indoor space is eliminated.

In the disclosed embodiments, the first and second wind pipe sections 20, 30 may alternatively be integrally formed structures. This increases the tightness of the air duct, and prevents air leakage at the junction between the first air duct section 20 and the second air duct section 30 in the air duct 10 from affecting the air outlet.

The first connection port 21 and the second connection port 22 form a curved air duct before, so that the air duct outlet 31 of the second air duct section 30 is arranged on the same side as and adjacent to the air inlet 101 of the casing 100.

As shown in connection with fig. 4 and 6, in some embodiments, the second connection port 22 is flared toward the first duct section 20 and the second connection port 22 is necked toward the second duct section 30.

In the disclosed embodiment, since the first duct section 20 is connected between the second duct section 30 and the outlet 102 of the cabinet 100. Therefore, the first air duct section 20 corresponds to the transition section, but in order to reduce the loss of the air volume in the first air duct section 20, it is necessary to optimize the structure of the first air duct section 20.

Thus, a portion of the side wall of the first connection port 21 may have a trapezoidal structure. Thus, not only is it inconvenient to connect with the air outlet 102, but it is also easy to leak air. Therefore, the first connection port 21 is provided with a mounting plate 211 extending along the vertical plane of the second side surface, and a set distance is provided between the top edge of the mounting plate 211 and the flaring structure of the second connection port 22 in the vertical direction, and the set distance can be set by itself according to the actual mounting space. In this way, the position is connected with the air outlet 102 through the mounting plate 211, so that the air outlet 102 is conveniently connected, and the tightness of the connection part can be ensured.

Therefore, the air in the second air duct can be guided, the blown-out air speed is faster, and the working efficiency of the air duct machine is improved.

In the embodiment of the disclosure, the rectangular pipe section has a third side surface and a fourth side surface which are adjacently arranged, the side edges of the third side surface and the fourth side surface are mutually perpendicular, the third side surface is provided with an air pipe air inlet 32, and the fourth side surface is provided with an air pipe air outlet 31; the air duct inlet 32 is connected to the second connection port 22 of the first air duct section 20, and the air duct outlet 31 is disposed on the air inlet 101 side of the casing 100.

As shown in connection with fig. 1 and 2, in some embodiments, a first air duct section 20 is configured to be disposed in communication with the same side of the enclosure 100, and a second air duct section 30 is disposed side-by-side with the first air duct section 20 and the enclosure 100; wherein the length of the second duct section 30 is greater than or equal to the overall length of the chassis 100 and the first duct section 20.
