In these embodiments, the through hole 215 is adjacent to the first side 211 of the baffle 21. When the baffle 21 is rotatably disposed on the bracket 10 through the operating member 22, the baffle 21 can be positioned adjacent to the first side 211. The operating member 22 serves as a fulcrum to rotate around the axis D1.

Referring to FIG. 4 , in some embodiments, the baffle 21 is arranged at the middle position of the bracket 10 in the second radial direction D3. In these embodiments, the bracket 10 is used to assemble a plurality of expansion components B. As shown in FIGS. 1 and 4 , the bracket 10 is used to assemble two expansion components B as an example, but the present case is not limited to this. It is worth noting that the bracket 10 of these embodiments can be installed with a plurality of expansion components B but is not limited to being able to install only a plurality of expansion components B. That is to say, the space 101 inside the bracket 10 allows a plurality of expansion components B to be installed. However, In use, only a single expansion component B can be installed on the inner side 101 of the bracket 10 .

As shown in Figure 1, two expansion elements B are provided on the inner side 101 of the bracket 10. The two expansion elements B are located at different positions of the bracket 10 in the second radial direction D3, and the two expansion elements B are located on the baffle 21 in the second radial direction D3. To both sides of D3, the baffle 21 can be adjusted to a horizontal state parallel to the upper surface 11 or the lower surface 12. In this state, the airflow flowing from the port 14 to each expansion component B is not blocked by the baffle 21 at all. , so that the airflow generated by fan C can fully dissipate heat to each expansion component B.

It is worth mentioning that since the angle of the baffle 21 in this case can be freely adjusted according to the usage requirements, when the thermal energy generated by the expansion components B in the bracket 10 is not the same, the heat dissipation energy required by each expansion component B is also different. , therefore, when two expansion components B are installed in the bracket 10 , the baffle 21 can also be pivoted to an inclined state inclined to the upper surface 11 and the lower surface 12 . In this state, the third side 213 of the baffle 21 Do not touch the upper part 11 or the lower part 12 (as shown in Figure 4). In this way, the openings of each expansion component B toward the fan C (the distance between the baffle 21 and the upper surface 11 or the lower surface 12 ) are different, and the airflow flowing from the fan C to each expansion component B can also be diverted and different. Therefore, the baffle 21 can divert the airflow entering the bracket 10 from the fan C, causing differences in the airflow to each expansion element B. Therefore, the baffle can be adjusted by directly operating some of the operating parts 22 located on the outside 102 of the bracket 10 21 angle to allow more airflow to flow through the expansion component B that generates more heat energy to accelerate heat dissipation.

Referring to FIGS. 5 and 6 , FIG. 5 is a schematic side view of the expansion module according to the second embodiment of the present invention, and FIG. 6 is a schematic side view of the expansion module according to the third embodiment of the present invention. In another use state, only a single expansion component B is installed in the bracket 10, and the expansion component B is adjacent to the upper surface 11, and the position adjacent to the lower surface 12 is in an idle state (no expansion component B is installed). In this state, the baffle 21 can be pivoted to the direction toward the lower surface 12 through the control of the operating member 22, so that the baffle 21 is blocked between the lower surface 12 of the bracket 10 and the expansion element B adjacent to the upper surface 11 to avoid the airflow of the fan C. Flow to the space where the expansion component B is not installed, and guide the airflow to the location where the expansion component B is installed, ensuring that the airflow entering the bracket 10 from the fan C can fully serve as a heat dissipator for the single expansion component B installed. use.

Similarly, referring to Figure 7, when a single expansion element B is installed in the bracket 10, and the expansion element B is located close to the lower surface 12, the baffle 21 can be controlled by the operating member 22 to pivot to the direction toward the upper surface 11, so that The baffle 21 blocks between the upper surface 11 of the bracket 10 and the expansion component B adjacent to the lower surface 12, preventing the airflow of the fan C from flowing to the space where the expansion component B is not installed, and guiding the airflow to the location where the expansion component B is installed. , to ensure that the airflow entering the bracket 10 from the fan C can be fully used for heat dissipation of the single expansion component B assembled.

Referring to Figures 5 and 6, in some embodiments, the shortest distance between the third side 213 of the baffle 21 and the operating member 22 has a first length L1, and the operating member 22 is assembled on the bracket 10 to the top. There is a second length L2 between 11 and 11, and there is a third length L3 between the position where the operating member 22 is assembled on the bracket 10 and the lower surface 12. The first length L1 is not less than the second length L2 and the third length L3.

That is to say, the first length L1 is at least equal to the second length L2 or the third length L3 (as shown in FIG. 6 ). Therefore, when only a single expansion component B is installed in the bracket 10 , the baffle 21 can be pivoted to have its third side 213 close to the upper surface 11 or the lower surface 12 , and the baffle 21 can become an upright state and completely block the port 14 and the lower surface 12 . Between the spaces where the expansion component B is not installed, airflow is prevented from entering the space where the expansion component B is not installed and the heat dissipation effect cannot be fully produced.

In some embodiments, the first length L1 is greater than the second length L2 or the third length L3 (as shown in FIG. 5 ). Thereby, when only a single expansion element B is disposed in the bracket 10 , the baffle 21 can be pivoted to have its third side 213 close to the upper surface 11 or the lower surface 12 , and since the first length L1 of the baffle 21 is greater than the second length L2 or the third length L3, therefore, the baffle 21 will contact the upper surface 11 or the lower surface 12 and be stopped before becoming upright, so that the baffle 21 becomes inclined. Taking the embodiment shown in FIG. 5 as an example, a single expansion component B is installed in the bracket 10, and the expansion component B is disposed close to the upper surface 11. When the first length L1 of the baffle 21 is greater than the third length L3 of the bracket 10 , the baffle 21 is blocked by the lower surface 12 and becomes an inclined plane compared to the lower surface 12 . In this way, the baffle 21 can not only block the airflow of the fan C from entering the space where the expansion component B is not installed, but the inclined baffle 21 can more smoothly guide the airflow to the location where the expansion component B is installed, thereby improving the heat dissipation efficiency. .

Referring to Figures 1 and 2, in some embodiments, the bracket 10 further includes a support member 15. The support member 15 includes a first part 151 and a second part 152 that are connected.

Thereby, the side surface 13 of the bracket 10 and the second part 152 of the support member 15 provide stable support at both ends of the operating member 22 , thereby improving the stability of the baffle 21 installed on the bracket 10 . In addition, the bracket 10 provides support for the other end of the operating member 22 by providing a plate-shaped support member 15. Compared with having the same entire surface structure as the side 13, in addition to making the bracket 10 lighter, The side of the bracket 10 provided with the support member 15 can also increase the area of the bracket 10 that is open to the outside, improve the heat dissipation pipe in the bracket 10, and ensure that the expansion component B installed on the inner side 101 of the bracket 10 will not affect normal operation due to overheating.

Referring to FIGS. 1 and 2 , in some embodiments, the length of the first part 151 of the support member 15 is greater than the length of the second part 152 . Therefore, since both ends of the first part 151 are connected to the inner edge of the port 14, the first part 151 can be stably supported by the port 14 and provide supporting force to the second part 152, thereby improving the stability of the second part 152 and ensuring that the support member 15 It can provide the best support with the smallest appearance and take into account the lightweight, stability and heat dissipation of the bracket 10.
