Therefore, the differences between this embodiment and the first embodiment will be described below, and the similarities will not be repeated. In this embodiment, the length and width (not shown) of the fan frame 171A are, for example, 120 mm, and the height H2 of the fan frame 171A is, for example, 25 mm. The second fastening holes 1221 can be adjusted according to the size of the fan frame 171A to correspond to the first fastening holes 1121. For example, in this embodiment, the second fastening holes 1221 correspond to the first fastening holes 1121 located in the middle section.

[0067] Please see Figure 8 and Figure 9 . Figure 8 This is a perspective view of the expansion card according to the third embodiment of the present invention. Figure 9 for Figure 8 A cross-sectional view of the expansion card.

[0068] The expansion card 10B of this embodiment is similar to the expansion card 10 of the first embodiment. Therefore, the differences between this embodiment and the first embodiment will be described below, and the similarities will not be repeated. In this embodiment, the length and width (not shown) of the fan frame 171B are, for example, 120 mm, and the height H3 of the fan frame 171B is, for example, 30 mm. The second fastening holes 1221 can be adjusted according to the size of the fan frame 171B to correspond to the first fastening holes 1121. For example, in this embodiment, the second fastening holes 1221 correspond to the innermost first fastening holes 1121.

[0069] In the expansion cards 10, 10A, and 10B of the first to third embodiments, the side located between the first side 111 and the third side 121 does not cover the accommodating space S, and the second fastening holes 1221 can be adjusted according to the dimensions of the fan frames 171, 171A, and 171B to correspond to the first fastening holes 1121, but are not limited thereto. For other embodiments, please refer to... Figure 10 and Figure 11 . Figure 10 This is a perspective view of the expansion card according to the fourth embodiment of the present invention. Figure 11 for Figure 10 An exploded view of the expansion card.

[0070] The expansion card 10C of this embodiment is similar to the expansion card 10 of the first embodiment. Therefore, the differences between this embodiment and the first embodiment will be described below, and the similarities will not be repeated. In this embodiment, the first housing 11C includes a first side portion 111C and a second side portion 112C. The second side portion 112C is connected to the first side portion 111C.

The opposite sides of the first side portion 111C are assembled to the two fourth side portions 122C. The second side portion 112C is assembled to one side where the third side portion 121C and the two fourth side portions 122C are connected. That is, in the expansion card 10C of this embodiment, the side located between the first side portion 111C and the third side portion 121C covers the accommodating space S through the second side portion 112C.

[0071] Furthermore, in this embodiment, the first side portion 111C has a plurality of first fastening holes 111C1 on opposite sides. Each fourth side portion 122C has a plurality of second fastening holes 122C1. These first fastening holes 111C1 and these second fastening holes 122C1 are arranged along a straight line, rather than in multiple rows.

That is, these second fastening holes 122C1 do not adjust the corresponding first fastening holes 111C1 according to the size of the fan frame 171C, that is, the position of the first housing 11C fixed to the second housing 12C does not adjust according to the size of the fan frame 171C.

[0072] In this embodiment, the number of fourth side portions 122C of the second housing 12C is two, but it is not limited to this. In other embodiments, the number of fourth side portions of the second housing may be only one.

[0073] According to the expansion card of the above embodiment, since these fans are in the form of fan frames and are fixed to the second housing, users can use commercially available fans with fan frames for replacement. This improves the convenience of replacing the expansion card's fans. Furthermore, the expansion card of this embodiment allows users to replace the fans with different sizes according to their needs, further increasing the flexibility of fan replacement.

[0074] Although the present invention has been disclosed above with reference to the foregoing embodiments, it is not intended to limit the present invention.
