For the purpose of clearness, many practical details will be described in the following description. However, it should be understood that these practical details are not intended to limit the present application. That is, in some embodiments of the present application, these practical details are not necessary. In addition, for the purpose of simplifying the drawings, some conventional structures and elements will be shown in the drawings in a simplified manner. In all the drawings, the same reference numerals will be used to denote the same or similar elements. If possible, features of different embodiments can be interchanged.

[0070] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art. By means of further guidance, definitions for the terms used herein are included to the extent consistent with the disclosure provided herein. These definitions should be interpreted as consistently as possible with the meaning of the relevant art.

[0071] Reference is made to Figures 1-5 . Figures 1-2 Fig. 1 is a perspective view of a network switch 100 according to an embodiment of the present application. Figure 2 Fig. 2 is a front view of the network switch 100 of Fig. 1. Figure 3 Fig. 3 is a top view of the network switch 100 of Fig. 1. Figure 2 Fig. 4 is a partial cross-sectional view of the network switch 100 of Fig. 1 taken along line A-A. Figure 4 Fig. 5 is a partial cross-sectional view of the network switch 100 of Fig. 1 taken along line B-B. Figure 2 Fig. 6 is a partial cross-sectional view of the network switch 100 of Fig. 1 taken along line C-C. Figure 5 Fig. 7 is a partial cross-sectional view of the network switch 100 of Fig. 1 taken along line D-D. Figure 2 Fig. 8 is a partial cross-sectional view of the network switch 100 of Fig. 1 taken along line E-E. Figures 1-5As shown, a network switch 100 includes a chassis 110, a line card 120, a heat dissipation module 130, and a housing 150, wherein the chassis 110, the line card 120, and the heat dissipation module 130 are at least partially located within the housing 150, and the housing 150 has an opening OP1 to at least partially expose the line card 120. In practice, the line card 120 is a vertical line card (VLC). Specifically, the chassis 110 includes a main board 111 mounted on a bottom portion, and the main board 111 is communicatively connected to the line card 120. Specifically, the main board 111 is used to process data transmitted by the line card 120, and is used to manage or control the network switch 100. The line card 120 includes a printed circuit board 122, a slot 121, and a plurality of connectors 123. The printed circuit board 122 is mounted on the chassis 110, and is arranged in a vertical configuration with the main board 111 and parallel to a first direction D1. In practice, the first direction D1 is a vertical direction, i.e., the printed circuit board 122 is vertically arranged. The slot 121 includes a first sub-slot 1211 and a second sub-slot 1212. According to actual conditions, the slot 121 is a single structure or a combined structure composed of the first sub-slot 1211 and the second sub-slot 1212, and the first sub-slot 1211 and the second sub-slot 1212 are connected to a side of the printed circuit board 122 away from the chassis 110, and are at least partially exposed to the opening OP1 of the housing 150. Further, the first sub-slot 1211 and the second sub-slot 1212 have a plurality of openings OP2 located at a side of the first sub-slot 1211 and the second sub-slot 1212 away from the chassis 110 and exposed to the opening OP1 of the housing 150. For example, the openings OP2 of the first sub-slot 1211 and the second sub-slot 1212 are arranged along the first direction D1, respectively. The connectors 123 are arranged on the printed circuit board 122 and aligned with the openings OP2 of the first sub-slot 1211 and the second sub-slot 1212. Therefore, electronic devices (not shown), such as fiber transceivers, can be horizontally inserted through the openings OP2 and at least partially accommodated in the first sub-slot 1211 or the second sub-slot 1212 to be connected with the connectors 123, wherein, Figure 5 is exemplified by the first sub-slot 1211. In addition, the heat dissipation module 130 is elastic along a second direction D2, and is clamped between the first sub-slot 1211 and the second sub-slot 1212 along the second direction D2, and the second direction D2 is perpendicular to the first direction D1.

[0072] In other words, the heat dissipation module 130 is supported between the first sub-slot 1211 and the second sub-slot 1212 by elasticity. In this way, the first sub-slot 1211 and the second sub-slot 1212 can not be processed to additionally increase locking elements, such as screw holes or studs, for fixing the heat dissipation module 130. This can not only save time, but also maintain the structural strength of the line card 120.

[0073] Furthermore, since the heat dissipation module 130 is elastically supported between the first sub-slot 1211 and the second sub-slot 1212, even if the distance between the first sub-slot 1211 and the second sub-slot 1212 has a large tolerance range, the heat dissipation module 130 can still be set between the first sub-slot 1211 and the second sub-slot 1212 of the connector 120, thus effectively improving the flexibility of the heat dissipation module 130 in use.

[0074] Moreover, since the heat dissipation module 130 is elastically supported between the first sub-slot 1211 and the second sub-slot 1212, the installation and removal of the heat dissipation module 130 can be completed simply and quickly.

[0075] In practical applications, such as Figure 4 As shown, the heat dissipation module 130 and the printed circuit board 122 are separated from each other, that is, the heat dissipation module 130 and the printed circuit board 122 do not contact each other, so as to improve the heat dissipation efficiency of the heat dissipation module 130.

[0076] Please refer to Figure 6 . Figure 6 For illustration Figures 2-4 A three-dimensional schematic diagram of the heat dissipation module 130. In this embodiment, as... Figures 2-4 , Figure 6 As shown, the heat dissipation module 130 includes a heat dissipation body 131, a first connecting seat 132, and a second connecting seat 133. The first connecting seat 132 is connected to one side of the heat dissipation body 131 along the second direction D2 and is configured to abut against the first sub-slot 1211. The second connecting seat 133 is connected to the other side of the heat dissipation body 131 along the second direction D2 and is configured to abut against the second sub-slot 1212. The second connecting seat 133 is elastic along the second direction D2, and after being elastically compressed along the second direction D2, it generates a force that tends to elastically return to its original position, so that the heat dissipation module 130 can be supported between the first sub-slot 1211 and the second sub-slot 1212.

[0077] Please refer to Figure 7 . Figure 7 To illustrate along Figure 6 A cross-sectional view of line segment BB. In this embodiment, as... Figures 6-7 As shown, the heat sink 131 includes a plurality of heat sink fins 1311 and a plurality of heat pipes 1312. The heat sink fins 1311 are connected to the heat pipes 1312. For example, the heat sink fins 1311 are stacked on top of each other along a second direction D2, while the heat pipes 1312 extend along the second direction D2 and pass through the heat sink fins 1311. Each of the heat pipes 1312 has a first end 1312a and a second end 1312b, the first end 1312a being connected to a first connector 132 and the second end 1312b being connected to a second connector 133.

[0078] Furthermore, such as Figures 5-6 As shown, the second connector 133 further includes a first body 1331 and a first positioning portion 1334. The second end 1312b of the heat pipe 1312 is connected to the first body 1331 of the second connector 133. The first positioning portion 1334 is connected to the edge 1331a of the first body 1331 and forms a first included angle α1 together with the surface 1331b of the first body 1331 away from the first connector 132. The first positioning portion 1334 is configured to abut against the second sub-slot 1212. The first connector 132 includes a second body 1321 and a second positioning portion 1322. The first end 1312a of the heat pipe 1312 is connected to the second body 1321 of the first connector 132. The second positioning portion 1322 is connected to the edge 1321a of the second body 1321 and forms a second included angle α2 together with the surface 1321b of the second body 1321 away from the second connector 133. The second positioning portion 1322 is configured to abut against the first sub-slot 1211. Specifically, by having the first positioning part 1334 and the second positioning part 1322 abut against the upper surfaces of the second sub-slot 1212 and the first sub-slot 1211 respectively, the stability of the heat dissipation module 130 installed between the wiring card 120 can be effectively improved. In practical applications, both the first included angle α1 and the second included angle α2 are right angles.

[0079] Furthermore, such as Figures 6-7 As shown, the network switch 100 also includes two heat-conducting plates 140. One of the heat-conducting plates 140 is disposed on the surface 1331b of the second connector 133 away from the first connector 132, and is sandwiched between the second connector 133 and the second sub-slot 1212. The other heat-conducting plate 140 is disposed on the surface 1321b of the first connector 132 away from the second connector 133, and is sandwiched between the first connector 132 and the first sub-slot 1211. By sandwiching the heat-conducting plates 140 between the connector 120 and the heat dissipation module 130, the efficiency of heat transfer can be effectively improved.

[0080] Please refer to Figure 8 . Figure 8 For illustration Figure 7 An enlarged schematic diagram of the range M. In this embodiment, the second connecting seat 133 further includes a connector 1332, while the first body 1331 has a through hole H. Figure 8 As shown, the connector 1332 is at least partially located within the perforation H and is elastically connected to the first body 1331 along the second direction D2, and the second end 1312b of the heat pipe 1312 is connected to the connector 1332.

[0081] More specifically, such as Figure 8The second connecting seat 133 further includes a protruding ring 1333. The protruding ring 1333 is disposed on the first body 1331 and located in the through hole H. The connecting member 1332 includes a sleeve 1332a, a clamping portion 1332b, a connecting portion 1332c, and an elastic element 1332d. The sleeve 1332a is slidably sleeved in the through hole H along the second direction D2 and accommodates the second end 1312b of the heat pipe 1312 therein. The clamping portion 1332b is located on one side of the protruding ring 1333 and is configured to press against the protruding ring 1333. The connecting portion 1332c is connected between the sleeve 1332a and the clamping portion 1332b along the second direction D2. The elastic element 1332d is located on the other side of the protruding ring 1333, and one end of the elastic element 1332d abuts against the protruding ring 1333, and the other end of the elastic element 1332d abuts against the sleeve 1332a. In practical applications, the elastic element 1332d can be a spring. In addition, the clamping portion 1332b and the connecting portion 1332c can be screw structures, and the sleeve 1332a can have a threaded hole to be threadedly coupled with the connecting portion 1332c.

[0082] Specifically, when the second connecting seat 133 is compressed toward the first connecting seat 132, the first body 1331 of the second connecting seat 133 moves toward the sleeve 1332a along with the protruding ring 1333, that is, the sleeve 1332a slides in the through hole H of the first body 1331 toward the protruding ring 1333, so that the elastic element 1332d is compressed between the protruding ring 1333 and the sleeve 1332a to generate elastic force, thereby causing the first body 1331 along with the protruding ring 1333 to elastically move away from the first connecting seat 132 along the second direction D2, so that elastic force is formed to support the heat dissipation module 130 between the first sub-slot 1211 and the second sub-slot 1212. In practical applications, in order to facilitate the sleeve 1332a to slide in the through hole H of the first body 1331, thermal paste can be applied between the sleeve 1332a and the first body 1331.

[0083] In summary, the technical solutions disclosed in the above embodiments of the utility model have at least the following advantages:

[0084] (1) Since the heat dissipation module is supported between the slots by elasticity, it is not necessary to process locking elements for fixing the heat dissipation module. This not only saves time, but also maintains the structural strength of the wiring card.

[0085] (2) Since the heat dissipation module is supported between the slots by elasticity, even if the distance between the slots has a large tolerance range, the heat dissipation module can still be arranged between the slots of the wiring card, so that the use flexibility of the heat dissipation module is effectively improved.

[0086] (3) Since the heat dissipation module is supported between the slots by elasticity, the mounting and dismounting of the heat dissipation module can be simply and quickly completed.

[0087] Although the utility model has disclosed as above in the embodiment, it is not used to limit the utility model, any person skilled in the art can make various changes and decorations without departing from the spirit and scope of the utility model, therefore the protection scope of the utility model should be defined as the appended claims.
