The centrifugal air duct is defined vertically and has an upper air outlet cavity, a middle inlet and outlet cavity, and a lower air outlet cavity. The upper air outlet cavity is connected to an upper air outlet 1 and an upper side air outlet 2, and the lower air outlet cavity is connected to a lower air outlet 3 and a lower side air outlet 4. The flow guiding component includes a main flow section 5, an upper flow guiding section 6, and a lower flow guiding section 7. The main flow guiding section 5 is installed in the middle inlet and outlet cavity and is used to guide the incoming air to the upper air outlet cavity and the lower air outlet cavity. The upper flow guiding section 6 is installed in the upper air outlet cavity and is used to guide the air entering the upper air outlet cavity to the upper air outlet 1 and the upper side air outlet 2. The lower flow guiding section 7 is installed in the lower air outlet cavity and is used to guide the air entering the lower air outlet cavity to the lower air outlet 3 and the lower side air outlet 4.

[0019] In this embodiment, the upper air outlet 1 is located at the top front side of the cabinet housing, there are two upper air outlets 2 distributed on both sides of the upper part of the cabinet housing, the lower air outlet 3 is located at the bottom front side of the cabinet housing, and there are two lower air outlets 4 distributed on both sides of the lower part of the cabinet housing.

[0020] This airflow guiding assembly mainly includes a main flow section 5, an upper flow guiding section 6, and a lower flow guiding section 7. The main flow guiding section 5, the upper flow guiding section 6, and the lower flow guiding section 7 are arranged correspondingly in the upper air outlet cavity, the middle air inlet and outlet cavity, and the lower air outlet cavity, so as to guide the incoming air to the upper air outlet cavity and the lower air outlet cavity, and then quickly and efficiently guide it to the upper air outlet 1, the upper side air outlet 2, the lower air outlet 3, and the lower side air outlet 4 for discharge.

[0021] To better understand this solution, further structural optimization will be performed below.

[0022] First is the main flow section 5, such as Figure 3 As shown, according to another embodiment of the present invention, the flow guiding component based on a simple centrifugal duct, wherein the main flow section 5 includes four main flow blocks 51, which are arranged circumferentially on the inner edge of the inlet and outlet air chamber.

[0023] In the embodiment, the centrifugal fan 8 is installed in the middle of the middle air inlet and outlet cavity. Since the centrifugal fan 8 is a centrifugal fan 8 without a volute, some supporting members in the centrifugal fan 8 are removed, and the simplicity of the centrifugal air duct is embodied. The design of the centrifugal fan 8 can design a larger size of the air wheel in the centrifugal fan 8, so that the centrifugal fan 8 can suck more air and produce less noise when running. Four main flow guide blocks 51 are arranged outside the centrifugal fan 8. Specifically, the line passing through the shaft center line and arranged horizontally is defined as the passing shaft center line. The four main flow guide blocks 51 include two upper main flow guide blocks 51 located above the passing shaft center line and distributed on opposite sides of the centrifugal fan 8, and two lower main flow guide blocks 51 located below the passing shaft center line and distributed on opposite sides of the centrifugal fan 8. Each upper main flow guide block 51 and each lower main flow guide block 51 are arc-shaped towards the side of the centrifugal fan 8, and the thickness of each upper main flow guide block 51 and each lower main flow guide block 51 along the direction of the passing shaft center line gradually increases from one end close to the centrifugal fan 8 to the other end.

[0024] The air thrown out of the air duct of the centrifugal fan 8 is efficiently guided into the upper air outlet cavity through the cooperation of the two upper main flow guide blocks 51, and is efficiently guided into the lower air outlet cavity through the cooperation of the two lower main flow guide blocks 51.

[0025] Secondly, the upper flow guide part 6, as shown in Figure 3 and Figure 4 According to another embodiment of the utility model, the upper flow guide part 6 includes an upper flow duct guide plate 61 and an upper horizontal flow guide plate 62. The upper flow duct guide plate 61 is arranged on the back of the upper air outlet cavity, and one end of the upper flow duct guide plate 61 is connected with the middle flow duct guide plate arranged on the back of the middle air inlet and outlet cavity. The other end of the upper flow duct guide plate 61 extends to the upper air outlet 1 to form the inner lining of the upper air outlet 1.

Specifically, when the centrifugal fan 8 installed in the middle of the air inlet and outlet cavity has a tendency to throw the air to the left side, then the two longitudinal flow guide plates 63 extend towards one of the ends of the middle air inlet and outlet cavity to be closer to the middle air inlet and outlet cavity, and the length of the one is greater than that of the other.

[0031] Then is the lower flow guide part 7, as Figure 3 and Figure 4 According to another embodiment of the utility model, the lower flow guide part 7 comprises a lower flow channel guide plate 71 and a lower horizontal flow guide plate 72, the lower flow channel guide plate 71 is arranged on the back of the lower air outlet cavity, and one end thereof is connected with the middle flow channel guide plate arranged on the back of the middle air inlet and outlet cavity, and the other end thereof extends to the lower air outlet 3 to form the inner lining of the lower air outlet 3; the lower horizontal flow guide plate 72 is two and is connected on both sides of the lower flow channel guide plate 71 one by one, and one end of the two lower horizontal flow guide plates 72 extends to form the inner lining of the corresponding lower side air outlet 4.

[0033] The lower flow guide part 7 further comprises a conical flow guide block 73 arranged at the middle of the front side of the lower flow channel guide plate 71, and the conical flow guide block 73 comprises a semi-cylinder in the upper section and a triangular prism in the lower section.
