[0069] Figure 3B for Figure 3A top view, and Figure 3C for along Figure 3A Schematic illustration of the III-III section line. Please also refer to Figure 3A , Figure 3B and Figure 3C , in the first embodiment, the wind guiding structure is a protruding windshield opening (not marked), wherein each protruding windshield opening (not marked) has, for example, a windshield 252 formed by a shell 222 made of stamped metal and an inlet. The air outlet 254 , and the windshield 252 protrudes from the first surface 222 a and can allow wind to enter the air inlet 254 . In addition, along the rotation direction of the fan blade 224 , the air inlet 254 is located at the upstream side and the windshield 252 is located at the downstream side, so that the windshield 252 can well block the wind flow and also catch the wind flow. In detail, if the fan blades 224 are set to rotate counterclockwise, each air inlet 254 is located in front of the windshield 252 along the countercloc...

[0081] Figure 7A is a schematic perspective view of the fan module in the second embodiment of the present invention, and Figure 7B for along Figure 7A Schematic diagram of the VII-VII section line. Please refer to Figure 3A , Figure 3C and Figure 7A and Figure 7B, the structure of this embodiment is substantially the same as that of the aforementioned first embodiment, and the obvious difference is that the wind guiding structure of this embodiment is set on the first surface 222a to be concave toward the inside of the housing 222 Multiple recessed pressurized openings. The concave pressurization openings are disposed along at least part of the fan cover 226 in the circumferential direction and arranged radially, and the range of the concave pressurization openings is also located within the range of the fan blades 224 . Another difference caused by the setting of the recessed pressurizing opening is that: the fan cover 226 can also cover the fan cover opening 2...

[0089] Figure 9A is a partial schematic diagram of the fan module of the third embodiment of the present invention, and Figure 9B is a cross-sectional view of the fan module 220 of the third embodiment. Please also refer to Figure 7B , Figure 9A and Figure 9B , the present embodiment differs from the foregoing second embodiment in that: the present embodiment is provided with a windshield 252 and a vane 256 sharing an air inlet 254 on the first surface 222a at the same time; that is, the opposite sides of the same air inlet 254 Windshield 252 and vane 256 are provided respectively. Therefore, along the rotation direction of the fan blade 244 , the structure of the wind guiding structure is the stator blade 256 , the air inlet 254 and the windshield 252 in sequence.
[0090] When the fan blades 224 (shown in Figure 3C ) rotates, the windshield 252 protruding from the first surface 222a can catch the airflow, prevent the airflow from leaking away and guide the captur...
