[0030] The locking unit 5 fixes the mounting plate 32 of the fan mounting bracket 3 to the connecting frame 12. The locking unit 5 passes through the mounting plate 32 and is locked into the connecting hole unit 121 of the connecting frame 12, so that the fan mounting bracket 3 is fixedly connected to the connecting frame 12, and the fan unit 2 is fixed to the fan mounting bracket 3 by the fan positioning unit 4.

[0031] The air guide cover 6 is placed on the base frame 31 of the fan mounting bracket 3 and is connected to the first end 111 of the outer shell 11, and is fixed to the base frame 31 of the fan mounting bracket 3.

[0032] Furthermore, in this embodiment, the fan unit 2 has two fans 21, but is not limited thereto. Each fan 21 has two connecting plates 22 located on opposite sides. The connecting frame unit 33 of the fan mounting bracket 3 has a plurality of connecting baffles 331 extending from the base frame 31 away from the base frame 31 and corresponding to the connecting plates 22 of the fan 21 respectively. The fan positioning unit 4 has a plurality of fan positioning members 41. The fan mounting bracket 3 passes through the connecting baffles 331 and the corresponding connecting plates 22 respectively, fixing the connecting plates 22 to the connecting baffles 331, thereby fixing the fan 21 to the connecting frame unit 33. Simply put, the fan mounting bracket 3 can accommodate two fans 21, and the fan positioning members 41 are used to connect the fans 21. Figure 3 , Figure 4 The connecting baffle 331 is connected and positioned with the connecting plate 22 as shown, so that the fan 21 is fixed to the connecting frame unit 33, but this is not a limitation.

[0033] Assembling, first, the mounting plate 32 of the fan fixing frame 3 is combined with the combined frame 12 of the PCIe card module 1 as shown in Figure 1 , Figure 3 so that the fan fixing frame 3 is fixedly combined with the combined frame 12 as shown in Figure 3 . Then, the combined blocking piece 331 of the combined frame unit 33 of the fan fixing frame 3 is combined with the combined plate 22 of the fan 21 through the fan positioning member 41 of the fan positioning unit 4 so that the fan 21 is fixed to the combined frame unit 33 as shown in Figure 3 , Figure 4 . Finally, the air guide cover 6 is covered on the base frame 31 of the fan fixing frame 3 and is fixed to the first end 111 of the shell 11 as shown in Figure 5 , and the assembling operation is completed. At this time, the fan 21, the fan fixing frame 3, the air guide cover 6 and the PCIe card module 1 are stably combined and integrated into one body, but the assembling operation sequence is not limited thereto.

[0034] Through the design that the mounting plate 32 of the fan fixing frame 3 is detachably combined with the combined frame 12 of the PCIe card module 1 and the application that the combined frame unit 33 of the fan fixing frame 3 can combine the fan unit 2, the mounting plate 32 is locked on the combined frame 12 through the locking unit 5 so that the fan fixing frame 3 is fixedly combined with the combined frame 12, and the fan unit 2 is fixed to the combined frame unit 33 of the fan fixing frame 3 through the fan positioning unit 4 so that the fan unit 2, the fan fixing frame 3 and the PCIe card module 1 are stably combined and integrated into one body, effectively avoiding the problem of instability caused by system vibration or external impact and achieving the fan unit 2 directly cooling the PCIe card module 1, which is good in overall cooling efficiency.

[0035] Here, it is to be noted that in the present embodiment, the combined frame 12 of the PCIe card module 1 further has a plurality of combined protrusions 123 arranged at intervals. The combined protrusions 123 divide the combined frame 12 into a plurality of airflow openings 124. The combined hole unit 121 of the combined frame 12 has a plurality of combined holes 122 respectively arranged on the combined protrusions 123. The mounting plate 32 of the fan fixing frame 3 has a plurality of mounting holes 321 corresponding to the combined holes 122. The locking unit 5 has a plurality of first locking members 51, and the first locking members 51 pass through the mounting holes 321 of the mounting plate 32 and are locked into the combined holes 122 of the combined hole unit 121 so that the mounting plate 32 of the fan fixing frame 3 is fixedly combined with the combined frame 12. That is, the mounting holes 321 of the mounting plate 32 of the fan fixing frame 3 areFigure 1 、 Figure 3 The mounting plate 32 of the fan fixing frame 3 is fixed to the combination frame 12 and the fan fixing frame 3 is butted against the combination frame 12 as shown in Figure 3 , but not limited thereto. It is mentioned that in the embodiment, the fan 21 of the fan unit 2 blows air to the first end portion 111 of the PCIe card module 1 for heat dissipation, but not limited thereto. The fan 21 can be designed to draw air from the second end portion 112 of the PCIe card module 1 for heat dissipation according to the actual installation position requirement.

[0036] It is mentioned that in the embodiment, the fan fixing frame 3 further comprises two fixing pieces 34 located at two opposite sides of the base frame 31 and respectively extended from the base frame 31 to the direction away from the base frame 31. The combination blocking piece 331 of the combination frame unit 33 is located between the fixing pieces 34. The air guide cover 6 comprises a cover body 61 spaced from the base frame 31 and covering the fan unit 2, and two air guide plates 62 extended from two opposite ends of the cover body 61 to the fixing pieces 34 of the base frame 31 and detachably fixed to the fixing pieces 34. The locking unit 5 further has a plurality of second locking pieces 52 for combining the fixing pieces 34 of the fan fixing frame 3 and the air guide plates 62. The second locking pieces 52 pass through the fixing pieces 34 and are locked into the air guide plates 62 to fix the air guide cover 6 to the fan fixing frame 3. In other words, the air guide cover 6 is combined with the fixing pieces 34 of the fan fixing frame 3 by the second locking pieces 52 as shown in Figure 5 , but not limited thereto. The air guide cover 6 is fixed to the fan fixing frame 3 by the second locking pieces 52 locking into the fixing pieces 34 of the fan fixing frame 3 and the air guide plates 62 of the air guide cover 6, and is butted against the first end portion 111 of the PCIe card module 1 as shown in Figure 5 .

[0037] Referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 、 Figure 8It should be noted that this embodiment also includes an NVLink bridge 7, which has two-phase spaced connectors 71. The housing 11 of the PCIe card module 1 also has a transmission interface (not shown) that can be electrically connected to the internal PCIe card. The housing 11 of the PCIe card module 1 is stacked with the housing 11 of another PCIe card module 1. The connectors 71 of the NVLink bridge 7 are respectively inserted into the transmission interfaces of the housing 11, so that the PCIe card of the PCIe card module 1 can transmit signals through the NVLink bridge 7. The PCIe card of the PCIe card module 1 is in the form of a GPU card, but is not limited thereto. That is to say, the PCIe card of the PCIe card module 1 can be connected to the PCIe card of another PCIe card module 1 through the NVLink bridge 7 to support data processing and transmission and improve performance. Figure 8 As shown, after stacking the housing 11 of the PCIe card module 1 with the housing 11 of another PCIe card module 1, the NV Link bridge 7 is inserted into the transmission interface of the housing 11, so that the PCIe card of the PCIe card module 1 can transmit signals through the NV Link bridge 7 to form an NV Link 2-Slot Bridge, but this is not limited to this. In particular, in this embodiment, when the housing 11 of the PCIe card module 1 is stacked with the housing 11 of another PCIe card module 1, the transmission interfaces are spaced by a first distance (not shown in the figure). A straight line L1 is defined as the horizontal extension line of the outer side of the cover body 61 of the air guide shroud 6, and a straight line L2 is defined as the horizontal extension line of the outer side of the base frame 31 of the fan mounting bracket 3. The distance d between the straight lines L1 and L2 (see Figure 7 The distance is less than the first distance. Furthermore, since the NV Link bridge 7 has specific dimensions, the design of the housing 11 of the PCIe card module 1, when stacked with another housing 11 of the PCIe card module 1, is based on the dimensions of the NV Link bridge 7. The vertical distance between one transmission interface and another transmission interface is the first distance. This first distance is used to ensure that the NV Link bridge 7 can be inserted into the transmission interface of the housing 11, and that the PCIe card of the PCIe card module 1 can transmit signals via the NV Link bridge 7. Therefore, the distance d between the straight line L1 of the horizontal extension line of the outer side of the cover body 61 of the air guide shroud 6 and the straight line L2 of the horizontal extension line of the outer side of the base 31 of the fan mounting bracket 3 is less than the first distance, thus allowing the PCIe card module 1 to... Figure 8The PCIe card module 1 is stacked and combined as shown, and the NV Link bridge 7 is ensured to be inserted into the transmission interface of the shell 11 and connected with the PCIe card. In other words, after the PCIe card module 1 is stacked and combined, the thickness of the cover body 61 of the shroud 6 and the thickness of the base frame 31 of the fan fixing frame 3 do not affect the distance between the transmission interface of the shell 11 of the PCIe card module 1 and the connector 71 of the NV Link bridge 7. In the embodiment, the distance d between the straight line L1 and the straight line L2 is 40.5 mm, and the first distance is 40.64 mm, but not limited thereto.

[0038] In particular, in the embodiment, the PCIe card module 1 further has a signal connection port 13 disposed in the shell 11 and located at the first end portion 111 and connected with the PCIe card. The signal connection port 13 is adjacent to the combined frame 12. When the shroud 6 is fixed to the fan fixing frame 3, one of the shroud plates 62 of the shroud 6 and the adjacent fan 21 are spaced apart by a wiring space 63 corresponding to the signal connection port 13. Among them, a transmission line 8 connected with the signal connection port 13 passes out of the shroud 6 from the wiring space 63. In short, as shown in Figure 5 、 Figure 6 The wiring space 63 is defined by one of the shroud plates 62 of the shroud 6 and the corresponding fan 21 to facilitate the storage and arrangement of the transmission line 8 connected with the signal connection port 13, but not limited thereto. It is noted that in the embodiment, when the fan unit 2 is fixed to the combined frame unit 33, the fan 21 and the mounting plate 32 of the fan fixing frame 3 define a containing space 35. Part of the power line 23 of each fan 21 is located in the containing space 35, and part of each power line 23 extends into the wiring space 63 and passes out of the shroud 6 from the wiring space 63. That is, the power line 23 of the fan 21 is routed as shown in Figure 6 Part of the power line 23 is located in the containing space 35, and the remaining part of the power line 23 is bent to extend into the wiring space 63 and passes out of the shroud 6 from the wiring space 63, and can be connected to an external power supply port (not shown), but not limited thereto. In particular, in the embodiment, the fan fixing frame 3 further includes a wire organizer 36 disposed on the base frame 31 and close to the mounting plate 32. The wire organizer 36 is used to fix the part of the power line 23 of the fan 21 located in the containing space 35 away from the wiring space 63. In short, as shown in Figure 3 、 Figure 6As shown, a cable organizer 36 is added to the base frame 31 at a position corresponding to the fan 21 which is farther away from the cable management space 63, to help organize the cable distribution of the power cord 23 of the fan 21 which is farther away from the cable management space 63 in the portion located in the accommodating space 35, so as to achieve the effect of cable management and aesthetics, but it is not limited to this.

[0039] Specifically, in this embodiment, the air guide shroud 6 further includes a cable clip 64 disposed on the air guide plate 62 near the cable management space 63. The cable clip 64 is detachably positioned to surround and restrict the transmission cable 8 and the power cable 23 located within the cable management space 63. That is, through the cable clip 64, the transmission cable 8 and the power cable 23 can be... Figure 5 The diagram shows the arrangement of the transmission line 8 and the power line 23 to achieve cable management, but this is not the only measure of its effectiveness.

[0040] Incidentally, in this embodiment, the base frame 31 of the fan mounting bracket 3 has an opening 311. The connecting baffles 331 of the connecting bracket unit 33 are disposed on the base frame 31 and are respectively located on two opposite sides of the opening 311. The fan mounting bracket 3 also includes a Mylar sheet 37 corresponding to the opening 311. The Mylar sheet 37 is attached to the outer side of the base frame 31 and covers the opening 311. That is to say, in this embodiment, due to practical structural considerations, the base frame 31 of the fan mounting bracket 3 and the connecting baffles 331 are integrally formed. The opening 311 in the base frame 31 of the fan mounting bracket 3 facilitates the design of the connecting baffles 331. Figure 1 , Figure 3 The diagram shows the fan 21 extending from two opposite sides of the opening 311 of the base frame 31 in a direction away from the rack, but this is not a limitation. Therefore, to prevent the airflow generated by the fan 21 from escaping from the opening 311 of the base frame 31, the Mylar sheet 37 is attached to the outer side of the base frame 31 and covers the opening 311, effectively ensuring overall heat dissipation efficiency. In this embodiment, the mounting plate 32 of the fan mounting bracket 3 also has multiple grille vents 322 corresponding to the airflow inlets 124. Simply put, the design of the grille vents 322, as shown in the diagram, effectively increases the airflow generated by the fan 21 of the fan unit 2 through the grille vents 322 and the airflow inlets 124 of the junction frame 12 of the PCIe card module 1, but this is not a limitation. Additionally, in this embodiment, the fan mounting bracket 3 further includes a support piece 38 disposed on the base frame 31 and extending away from the connecting frame 12. The support piece 38 and the mounting plate 32 are located on opposite sides of the opening 311 of the base frame 31, as shown in the figure. The support piece 38 can cooperate with and be locked to a frame iron piece (not shown) inside a system (not shown) to achieve the effect of assisting in supporting the whole, but is not limited thereto.

[0041] In summary, the PCIe device with the heat dissipation function, the mounting plate 32 of the fan fixing frame 3 is detachably combined with the combined frame 12 of the PCIe card module 1, and the combined frame unit 33 of the fan fixing frame 3 is combined with the fan unit 2, the mounting plate 32 is locked on the combined frame 12 by the locking unit 5, so that the fan fixing frame 3 is fixedly connected to the combined frame 12, and the fan unit 2 is fixed on the combined frame unit 33 of the fan fixing frame 3 through the fan positioning unit 4, so that the fan unit 2, the fan fixing frame 3 and the PCIe card module 1 are stably combined and integrated, the problem of instability caused by system vibration or external impact is effectively avoided, and the fan unit 2 directly dissipates heat for the PCIe card module 1, and the overall heat dissipation efficiency is good.
