[0051] It should be noted that the first fan baffle, although the first fan baffle assembly in the embodiment includes one first active fan baffle 43 and two first passive fan baffles 44, this setting is not a limitation of the utility model, and other settings can be used by those skilled in the art in other embodiments without deviating from the principles of the utility model, for example, the first fan baffle assembly includes one first active fan baffle 43 and a plurality of first passive fan baffles 44, which does not deviate from the basic principles of the utility model, and thus falls within the scope of protection of the utility model.

[0052] It should be noted that the first active fan baffle 43 and the first passive fan baffle 44, although the first active fan baffle 43 in the embodiment is arranged between the two first passive fan baffles 44, this setting is not a limitation of the utility model, and other settings can be used by those skilled in the art in other embodiments without deviating from the principles of the utility model, for example, the first active fan baffle 43 is arranged at the upper end or lower end of the two first passive fan baffles 44, which does not deviate from the basic principles of the utility model, and thus falls within the scope of protection of the utility model.

[0053] Referring to Figure 3 , the first fan baffle further includes a hinge shaft 35, and the first connecting rod 42 is provided with three hinge holes. The hinge shaft 35 is arranged in the hinge hole to hinge the first fan baffle and the first connecting rod 42. The first driving member 41 is a rotary motor. The first driving member 41 is connected to the first active fan baffle 43, and the first driving member 41 can drive the first active fan baffle 43 to rotate. When the first active fan baffle 43 rotates, the first connecting rod 42 synchronously rotates the two first passive fan baffles 44. And the three fan baffles always maintain a parallel state.

[0054] Specifically, the first fan baffle assembly can make the airflow discharged from the upper fan outlet 21 flow to the upper case outlet 12 or the lower case outlet 13.

[0055] The second fan baffle assembly is arranged at the lower fan outlet 22, and the second fan baffle assembly is used to control the direction of the airflow discharged from the lower fan outlet 22. The second fan baffle assembly includes a second driving member 51, a second connecting rod 52, and three second fan baffles, including one second active fan baffle 53 and two second passive fan baffles 54. The structure of the second fan baffle assembly is the same as that of the first fan baffle assembly, and thus will not be described again. The second fan baffle assembly can make the airflow discharged from the lower fan outlet 22 flow to the upper case outlet 12 or the lower case outlet 13.

[0056] In the embodiment, there are the following three air guiding modes:

[0057] The first mode is that referring to the above-mentioned first mode, the first air guiding assembly makes the air flow from the upper air outlet 21 of the fan flow to the upper air outlet 12 of the casing, and the second air guiding assembly makes the air flow from the lower air outlet 22 of the fan flow to the lower air outlet 13 of the casing.

[0058] The second mode is that referring to the above-mentioned first mode, the first air guiding assembly makes the air flow from the upper air outlet 21 of the fan flow to the upper air outlet 12 of the casing, and the second air guiding assembly makes the air flow from the lower air outlet 22 of the fan flow to the lower air outlet 13 of the casing. Figure 5

[0059] The third mode is that referring to the above-mentioned first mode, the first air guiding assembly makes the air flow from the upper air outlet 21 of the fan flow to the lower air outlet 13 of the casing, and the second air guiding assembly makes the air flow from the lower air outlet 22 of the fan flow to the lower air outlet 13 of the casing. Figure 6

[0060] It should be noted that, although the first air guiding assembly and the second air guiding assembly are included in the embodiment, the first air guiding assembly is arranged at the upper air outlet 21 of the fan, and the second air guiding assembly is arranged at the lower air outlet 22 of the fan, but this arrangement is not a limitation of the present application, and other arrangements can be adopted by those skilled in the art in other embodiments without departing from the principles of the present application, for example, a third air guiding assembly is arranged at the left air outlet of the fan, and a fourth air guiding assembly is arranged at the right air outlet of the fan, which does not deviate from the basic principles of the present application, and thus falls within the protection scope of the present application.

[0061] Further, the air guiding system further includes casing air guiding plates. A rotatable upper casing air guiding plate is arranged at the upper air outlet 12 of the casing, and a rotatable lower casing air guiding plate (not shown in the figure) is arranged at the lower air outlet 13 of the casing.
