[0007] The server provided by the embodiment of the present application arranges the first mounting group and the second mounting group on the side panel in rotational symmetry and allows the backplane module to rotate relative to the shell. Before the backplane module rotates relative to the shell, the first mating groups on both sides of the first backplane can be connected to the first mounting group, and the second mating groups on both sides of the second backplane can be connected to the second mounting group; after the backplane module rotates relative to the shell, the first mating groups on both sides of the first backplane can be connected to the second mounting group, and the second mating groups on both sides of the second backplane can be connected to the first mounting group. The function card modules connected to different backplanes also rotate with the backplane module, so that the orientation of the function card modules can be changed. Thus, the server can meet the diverse configuration requirements of computing devices.

[0008] In one possible embodiment, the server provided in the embodiment of the present application, the side panel includes a first side panel and a second side panel, the first mounting group includes a first mounting portion and a second mounting portion, the second mounting group includes a third mounting portion and a fourth mounting portion, the first mounting portion and the third mounting portion are arranged on the first side panel, and the second mounting portion and the fourth mounting portion are arranged on the second side panel; the first mounting portion is the same as the fourth mounting portion, and the second mounting portion is the same as the third mounting portion; the first mating group includes a first mating portion and a second mating portion, the first mating portion is used to connect with the first mounting portion or the fourth mounting portion, and the second mating portion is used to connect with the second mounting portion or the third mounting portion; the second mating group includes a third mating portion and a fourth mating portion, the third mating portion is used to connect with the second mounting portion or the third mounting portion, and the fourth mating portion is used to connect with the first mounting portion or the fourth mounting portion.

[0009] In one possible embodiment, in the server provided by the embodiment of the present application, the first mounting portion, the second mounting portion, the third mounting portion, and the fourth mounting portion are respectively the first slide, the second slide, the third slide, and the fourth slide; the width of the first slide is greater than the width of the second slide; the width of the fourth slide is greater than the width of the third slide; and the width of the first slide is the same as the width of the fourth slide, and the width of the second slide is the same as the width of the third slide; the first matching portion, the second matching portion, the third matching portion, and the fourth matching portion are respectively the first slider, the second slider, the third slider, and the fourth slider; the first slider matches the first slide and the fourth slide, the second slider matches the second slide and the third slide; the third slider matches the second slide or the third slide; and the fourth slider matches the first slide or the fourth slide. All four mounting portions are configured as slides, and all four matching portions are configured as sliders, so that the ends of the first backplane and the second backplane respectively enter the shell along the slides, making the installation method of the first backplane and the second backplane relatively simple. Changing the width of the slideway to prevent the first backplane or the second backplane from being installed upside down is relatively simple. In addition, when the backplane module is rotated 180° as a whole, the insertion and installation of the backplane module are relatively simple.

[0010] In one possible implementation, in the server provided in an embodiment of the present application, the backplane module is centrally located in the housing along a first direction. Function card modules in the housing's accommodating areas on either side of the backplane module are substantially symmetrical about the backplane module. Therefore, even after the position of the function card modules is changed, they will not exceed the restricted ranges of the first and second sides of the housing.

The link formed by the first connector, the first cable and the second connector can be used to transmit high-speed signals. Transmitting high-speed signals through the first cable can reduce signal loss and improve signal transmission quality. When the first connector and the second connector are electrically connected through the first cable, the routing method of the first cable can be flexibly set according to the functional card module to be connected.

A second mounting slot is provided on the second backplane, and a second mounting portion is provided on the second connector, the second mounting portion being located in the second mounting slot and having a clearance fit with the second mounting slot. A gap is provided between the second mounting portion and the second bottom wall and second side wall of the second mounting slot, allowing the second connector to move within a small range relative to the second backplane. Thus, when the second connector is not fully aligned with the second function card connector, the movement of the second connector within a small range can facilitate alignment of the second connector with the second function card connector.

[0013] In one possible implementation, in the server provided in an embodiment of the present application, a first elastic member is disposed between the bottom wall of the first mounting slot and the first mounting portion. The rebound force of the first elastic member can compensate for tolerances of the first connector along the first direction, and the first elastic member can apply pressure to the first connector, thereby ensuring a more reliable electrical connection between the first connector and the first function card connector on the function card module.

The resilient force of the second elastic member can compensate for tolerances of the second connector along the first direction, and the second elastic member can apply pressure to the second connector, thereby ensuring a more reliable electrical connection between the second connector and the second function card connector of the function card module.

[0015] In one possible implementation, the server provided in an embodiment of the present application further includes a second cable for electrically connecting some functional card modules to the backplane module. The length of the second cable can be adjusted based on the spacing between the power module and the adapter board, allowing the server to accommodate power modules of varying specifications. This allows for flexible selection of the specifications of the power supply units electrically connected to the power modules, allowing the server to meet diverse configuration requirements of computing devices.

[0016] In one possible implementation, the server provided in an embodiment of the present application further includes a fan module, the fan module being disposed between the first backplane and the second backplane; the fan module including multiple fans, each having a fifth connector; the adapter board having multiple connector groups, each connector group corresponding to the fifth connector; each connector group including a sixth connector and a seventh connector, the sixth and seventh connectors being rotationally symmetrical; the fifth connector being plugged into one of the sixth and seventh connectors.

[0097] Since the first mounting portion 1131 is identical to the fourth mounting portion 1142, and the second mounting portion 1132 is identical to the third mounting portion 1141, Figure 9 In the embodiment, after the backplane module 120 is rotated 180°, the first mating portion 1211 can be connected to the fourth mounting portion 1142 , the second mating portion 1212 is connected to the third mounting portion 1141 , the third mating portion 1221 is connected to the second mounting portion 1132 , and the fourth mating portion 1222 is connected to the first mounting portion 1131 .

[0098] Therefore, before the backplane module 120 is rotated, the two ends of the first backplane 121 can be connected to the first mounting portion 1131 and the second mounting portion 1132 respectively, and the two ends of the second backplane 122 can be connected to the third mounting portion 1141 and the fourth mounting portion 1142 respectively; after the backplane module 120 is rotated 180°, the two ends of the first backplane 121 can be connected to the third mounting portion 1141 and the fourth mounting portion 1142 respectively, and the two ends of the second backplane 122 can be connected to the first mounting portion 1131 and the second mounting portion 1132 respectively.

[0099] Please continue to see Figure 7 As shown, the function card module 130 can be a processor module 131 , a memory module 132 , a power module 133 or a PCIE card module 134 .

[0100] The processor module 131 and the memory module 132 are electrically connected to the first backplane 121, and the processor module 131 and the memory module 132 are facing the first side 110a of the shell 110. The PCIE card module 134 is electrically connected to the second backplane 122. The power module 133 is electrically connected to the adapter board 123, and the power module 133 and the PCIE card module 134 are facing the second side 110b of the shell 110.

[0101] The power supply module 133 is electrically connected to the power supply unit 300 of the computing device 10 through a first electrical connector 400, and the processor module 131, memory module 132 or PCIE card module 134 is electrically connected to the switch 600 or the processor module 131, memory module 132 or PCIE card module 134 in other servers 100 through a second electrical connector 500.

[0102] When the backplane module 120 rotates relative to the shell 110, the functional card module 130 electrically connected to the backplane module 120 also rotates with the backplane module 120. For example, the power module 133 and the PCIE card module 134 can be rotated to the first side 110a toward the shell 110, and the processor module 131 and the memory module 132 can be rotated to the second side 110b toward the shell 110.

[0103] When the first electrical connector 400 electrically connected to the power supply unit 300 extends from the rear end 200b along the third direction of the cabinet 200, the power module 133 can be directed toward the second side 110b of the shell 110. When the first electrical connector 400 electrically connected to the power supply unit 300 in the computing device 10 extends from the front end 200a along the third direction Z of the cabinet 200, the backplane module 120 can be rotated 180° so that the power module 133 is directed toward the first side 110a of the shell 110, so that the server 100 can be adapted to computing devices 10 with different positions of the first electrical connector 400. When the second electrical connector 500 extends from the front end 200a along the third direction Z of the cabinet 200, the processor module 131 and the memory module 132 can be directed toward the first side 110a of the housing 110. When the second electrical connector 500 extends from the rear end 200b along the third direction Z of the cabinet 200, the backplane module 120 can be rotated 180°, so that the processor module 131 and the memory module 132 face the second side 110b of the housing 110. This facilitates electrical connection with the switch 600 or other function card modules 130 in the server 100 via the second electrical connector 500, allowing the server 100 to adapt to computing devices 10 with different first electrical connectors 400 positions. Thus, the server 100 can meet the diverse configuration requirements of computing devices 10.

[0104] The server 100 provided in the embodiment of the present application is provided with a housing 110, a backplane module 120 and a plurality of function card modules 130. The housing 110 includes a bottom plate 111 and side plates 112 connected to both sides of the bottom plate 111; the side plates 112 have a first mounting group 113 and a second mounting group 114; the first mounting group 113 and the second mounting group 114 are arranged along a first direction X and are rotationally symmetrical with each other; the backplane module 120 includes a first backplane 111 and a second mounting group 114; 21. The second backplane 122 and the adapter plate 123. The first backplane 121 and the second backplane 122 are connected on both sides of the adapter plate 123 along the first direction X. The distance between the first backplane 121 and the second backplane 122 is the same as the distance between the first installation group 113 and the second installation group 114. Some function card modules 130 are electrically connected to the first backplane 121, some function card modules 130 are electrically connected to the second backplane 122, and some function card modules 130 are electrically connected to the adapter plate 123. By making the first mounting group 113 and the second mounting group 114 rotationally symmetrical and allowing the backplane module 120 to rotate relative to the shell 110, before the backplane module 120 rotates relative to the shell 110, the first mating group 121a on both sides of the first backplane 121 can be connected to the first mounting group 113, and the second mating group 122a on both sides of the second backplane 122 can be connected to the second mounting group 114; after the backplane module 120 rotates relative to the shell 110, the first mating group 121a on both sides of the first backplane 121 can be connected to the second mounting group 114, and the second mating group 122a on both sides of the second backplane 122 can be connected to the first mounting group 113, and the function card module 130 connected to different backplanes also rotates with the backplane module 120, so that the orientation of the function card module 130 can be changed. Thus, the server 100 can meet the diverse configuration requirements of the computing device 10.

[0105] Figure 11 Schematic diagram of the installation of the shell and backplane module in the server provided in the embodiment of the application Figure 3 ; Figure 12 Schematic diagram of the installation of the shell and backplane module in the server provided in the embodiment of the application Figure 4 .

[0106] See also Figure 11 and Figure 12As shown, the first mounting portion 1131, the second mounting portion 1132, the third mounting portion 1141 and the fourth mounting portion 1142 are respectively the first slide 1131a, the second slide 1132a, the third slide 1141a and the fourth slide 1142a extending along the third direction Z; the width of the first slide 1131a is greater than the width of the second slide 1132a; the width of the fourth slide 1142a is greater than the width of the third slide 1141a; and the width of the first slide 1131a is the same as the width of the fourth slide 1142a, and the width of the second slide 1132a is the same as the width of the third slide 1141a.

[0107] The first mounting portion 1131, the second mounting portion 1132, the third mounting portion 1141 and the fourth mounting portion 1142 are all arranged as slides extending along the third direction Z, so that the two ends of the first back panel 121 and the second back panel 122 respectively enter the shell 110 along the slides, making the installation method of the first back panel 121 and the second back panel 122 relatively simple.

[0108] The first slideway 1131a has a first width W1 along the first direction X, the second slideway 1132a has a second width W2 along the first direction X, the third slideway 1141a has a third width W3 along the first direction X, and the fourth slideway 1142a has a fourth width W4 along the first direction X. The first width W1 is greater than the second width W2, and the fourth width W4 is greater than the third width W3.

[0109] The first matching portion 1211, the second matching portion 1212, the third matching portion 1221 and the fourth matching portion 1222 are respectively the first slider 1211a, the second slider 1212a, the third slider 1221a and the fourth slider 1222a; the first slider 1211a matches the first slide 1131a and the fourth slide 1142a, the second slider 1212a matches the second slide 1132a and the third slide 1141a, the third slider 1221a matches the second slide 1132a or the third slide 1141a; the fourth slider 1222a matches the first slide 1131a or the fourth slide 1142a.

[0110] The size of the first slider 1211a is close to the first width W1 and the fourth width W4. Figure 11 In the embodiment, the first slider 1211a is inserted into the first slideway 1131a; the size of the second slider 1212a is close to the second width W2 and the third width W3. Figure 11 Since the first width W1 is greater than the width, when only the first back plate 121 rotates 180 degrees, the first back plate 121 cannot be installed in the first installation group 113, thereby preventing the first back plate 121 from being installed upside down.

[0111] The principle of the second installation group 114 preventing the second back plate 122 from being installed upside down is the same as the principle of the first installation group 113 preventing the first back plate 121 from being installed upside down, and will not be repeated here.

[0112] The first width W1 is equal to the fourth width W4, and the second width W2 is equal to the third width W3. Therefore, please continue to refer to Figure 12 As shown, when the backplane module 120 rotates 180° as a whole, the first slider 1211a of the first backplane 121 can be inserted into the fourth slide 1142a, and the second slider 1212a of the first backplane 121 is inserted into the third slide 1141a; the third slider 1221a of the second backplane 122 is inserted into the second slide 1132a, and the fourth slider 1222a of the second backplane 122 is inserted into the first slide 1131a.

[0113] Changing the width of the slideway to prevent the first backplane 121 or the second backplane 122 from being installed upside down is relatively simple. In addition, when the backplane module 120 is rotated 180° as a whole, the insertion and installation of the backplane module 120 are relatively simple.

[0114] Figure 13 This is a structural diagram of the backplane module in the server provided in an embodiment of the present application.

[0115] Please continue to see Figure 7 and Figure 13 As shown, a guide column 1111 is further provided on the base plate 111, and a guide hole 125 corresponding to the guide column 1111 is further provided on the side of the first back plate 121 and the second back plate 122 facing the base plate 111. When the back plate module 120 is installed, each slider in the back plate module 120 slides along the corresponding slide rail toward the bottom wall 111 of the shell 110, and the guide columns 1111 can be inserted one by one into the guide holes 125 to position the back plate module 120.

[0116] In a possible implementation, the backplane module 120 is centrally disposed along the first direction X in the housing 110 .

[0117] For details, please refer to Figure 8 and Figure 9 As shown, the accommodation space in the housing 110 can be divided into a first accommodation area 110c, a second accommodation area 110d and a third accommodation area 110e. The third accommodation area 110e is located along the first direction X between the first accommodation area 110c and the second accommodation area 110d.

[0118] The backplane module 120 can be set in the third accommodating area 110e, that is, the backplane module 120 is roughly centered in the housing 110 along the first direction X. The function card modules 130 located on both sides of the backplane module 120 can be located in the first accommodating area 110c or the second accommodating area 110d. Since the backplane module 120 is centered in the housing 110 along the first direction X, the function card modules 130 located in the first accommodating area 110c and the second accommodating area 110d are roughly symmetrical along the backplane module 120. When the backplane module 120 and the function card module 130 connected to the backplane module 120 are rotated 180°, the function card module 130 originally located in the first accommodating area 110c moves to the second accommodating area 110d, and the function card module 130 originally located in the second accommodating area 110d moves to the first accommodating area 110c. Since the function card modules 130 in the first accommodating area 110c and the second accommodating area 110d are roughly symmetrical along the backplane module 120, the position of the function card module 130 will not exceed the limit range of the first side 110a and the second side 110b of the shell 110 after changing.

[0119] Figure 14 A schematic structural diagram of a backplane module in a server provided in an embodiment of the present application from another angle; Figure 15 for Figure 14 Explosion diagram.

[0120] See also Figure 14 and Figure 15 As shown, the first backplane 121 has a first connector 1213, which is used to plug into the functional card module 130 electrically connected to the first backplane 121; the second backplane 122 has a second connector 1223, which is used to plug into the functional card module 130 electrically connected to the second backplane 122; the backplane module 120 also includes a first cable 124, one end of the first cable 124 is electrically connected to the first connector 1213, and the other end is electrically connected to the second connector 1223.

[0121] There can be multiple first connectors 1213, and the processor module 131 and the memory module 132 have first function card connectors (not shown in the figure) that are arranged one-to-one corresponding to the first connector 1213. The first function card connector is plugged into the first connector 1213, thereby electrically connecting the processor module 131 and the memory module 132 to the first connector 1213.

[0122] There can be multiple second connectors 1223, and the PCIE card module 134 has a second function card connector (not shown in the figure) that is arranged one-to-one with the second connector 1223. The second function card connector is plugged into the second connector 1223, thereby electrically connecting the PCIE card module 134 and the second connector 1223.

[0123] The two ends of the first cable 124 are respectively connected to the first connector 1213 and the second connector 1223, thereby, the functional card modules 130 located on both sides of the backplane module 120 can be electrically connected through the transmission link formed by the first connector 1213, the first cable 124 and the second connector 1223. Among them, the link formed by the first connector 1213, the first cable 124 and the second connector 1223 can be used to transmit high-speed signals. Transmitting high-speed signals through the first cable 124 can reduce signal loss and improve signal transmission quality. It should be noted that when the first connector 1213 and the second connector 1223 are electrically connected through the first cable 124, the routing method of the first cable 124 can be flexibly set according to the functional card module 130 to be connected. In addition, a wire clamp 1234 is also provided on the adapter plate 123, and the wire clamp 1234 can be used to fix the first cable 124.

[0124] Figure 16 A schematic diagram of the installation of a first backplane and a first connector in a server provided in an embodiment of the present application; Figure 17 This is a schematic diagram of the installation of the second backplane and the second connector in the server provided in an embodiment of the present application.

[0125] See also Figure 16 and Figure 17 As shown, the first back panel 121 has a first mounting groove 1214, the first connector 1213 has a first mounting portion 1213a, the first mounting portion 1213a is located in the first mounting groove 1214 and the first mounting portion 1213a is loosely fitted with the first mounting groove 1214; the second back panel 122 has a second mounting groove 1224, the second connector 1223 has a second mounting portion 1223a, the second mounting portion 1223a is located in the second mounting groove 1224 and the second mounting portion 1223a is loosely fitted with the second mounting groove 1224.

[0126] The first connector 1213 includes a first plugging portion 1213b and a first mounting portion 1213a connected to the first plugging portion 1213b. The first plugging portion 1213b is configured to plug into the function card module 130. A first mounting slot 1214 is provided on the first backplane 121, and the first mounting portion 1213a is located within the first mounting slot 1214. The first mounting slot 1214 includes a first bottom wall 1214a and first side walls 1214b surrounding the first bottom wall 1214a. The interior space of the first mounting slot 1214 can be larger than the outer contour of the first mounting portion 1213a. A gap exists between the first mounting portion 1213a and the first bottom wall 1214a and first side walls 1214b of the first mounting slot 1214, allowing the first connector 1213 to move within a small range relative to the first backplane 121. Thus, when the first connector 1213 is not completely aligned with the first function card connector, the movement of the first connector 1213 within a small range can facilitate the alignment of the first connector 1213 with the first function card connector.

[0127] The second connector 1223 includes a second plugging portion 1223b and a second mounting portion 1223a connected to the second plugging portion 1223b. The second plugging portion 1223b is configured to plug into the function card module 130. A second mounting slot 1224 is provided on the second backplane 122, and the second mounting portion 1223a is located within the second mounting slot 1224. The second mounting slot 1224 includes a second bottom wall 1224a and second side walls 1224b surrounding the second bottom wall 1224a. The interior of the second mounting slot 1224 can be larger than the outer contour of the second mounting portion 1223a. A gap exists between the second mounting portion 1223a and the second bottom wall 1224a and second side walls 1224b of the second mounting slot 1224, allowing the second connector 1223 to move within a small range relative to the second backplane 122. Thus, when the second connector 1223 is not completely aligned with the second function card connector, the movement of the second connector 1223 within a small range can facilitate the alignment of the second connector 1223 with the second function card connector.

[0128] Please continue to see Figure 16 and Figure 17 As shown, a first elastic member 1215 is provided between the first bottom wall 1214a of the first mounting groove 1214 and the first mounting portion 1213a; a second elastic member 1225 is provided between the second bottom wall 1224a of the second mounting groove 1224 and the second mounting portion 1223a.

[0129] The first elastic member 1215 is in a compressed state. When the first connector 1213 has a dimensional tolerance along the first direction X, the tolerance of the first connector 1213 along the first direction X can be compensated by the rebound force of the first elastic member 1215, and the first elastic member 1215 can apply pressure on the first connector 1213, so that the electrical connection between the first connector 1213 and the first function card connector on the function card module 130 is more reliable.

[0130] Similarly, the second elastic member 1225 is in a compressed state. When the second connector 1223 has a dimensional tolerance along the first direction X, the tolerance of the second connector 1223 along the first direction X can be compensated by the rebound force of the second elastic member 1225, and the second elastic member 1225 can apply pressure on the second connector 1223, so that the electrical connection between the second connector 1223 and the second function card connector of the function card module 130 is more reliable.

[0131] Please continue to see Figure 15 As shown, the adapter board 123 includes a third connector 1231 and a fourth connector 1232 , both of which are used to plug into the function card module 130 ; the third connector 1231 and the fourth connector 1232 are electrically connected through internal wiring of the adapter board 123 .

[0132] The adapter board 123 is provided with a third connector 1231 and a fourth connector 1232, which can be connected via internal wiring of the adapter board 123. The first back panel 121 has a first opening 1216, into which the third connector 1231 can be inserted, and the second back panel 122 has a second opening 1226, into which the fourth connector 1232 can be inserted.

[0133] The processor module 131 and the memory module 132 have a third function card connector (not shown in the figure), which plugs into the third connector 1231 in a one-to-one correspondence, thereby electrically connecting the processor module 131 and the memory module 132 to the adapter board 123. The PCIE card module 134 has a fourth function card connector (not shown in the figure), which plugs into the fourth connector 1232 in a one-to-one correspondence, thereby electrically connecting the PCIE card module 134 to the adapter board 123.

[0134] The link formed by the third connector 1231 , the internal wiring of the adapter board 123 and the fourth connector 1232 can transmit low-speed signals or electrical energy, thereby reducing interference between low-speed signals and high-speed signals and making full use of the internal structure of the adapter board 123 .

[0135] Please continue to see Figure 7 、 Figure 14 and Figure 15 As shown, the server 100 further includes a second cable 140 , which is used to electrically connect part of the function card module 130 and the backplane module 120 .

[0136] For example, the power module 133 is slightly smaller than the PCIE card module 134 along the first direction X. When the power module 133 is aligned with the first side 110a or the second side 110b of the housing 110, there is still a gap between the power module 133 and the backplane module 120, and the power module 133 cannot be electrically connected to the adapter board 123. A second cable 140 can be provided in the server 100, with one end of the second cable 140 electrically connected to the power module 133 and the other end of the second cable 140 electrically connected to the adapter board 123. The length of the second cable 140 can be adjusted based on the gap between the power module 133 and the adapter board 123, allowing the server 100 to use power modules 133 of different specifications. Consequently, the specifications of the power supply unit 300 electrically connected to the power module 133 can also be flexibly selected, allowing the server 100 to meet the diverse configuration requirements of the computing device 10.

[0137] The function card module 130 may also be a hard disk module. The size of the hard disk module along the first direction X is also smaller than the size of the processor module 131 along the first direction X. The second cable 140 may also be used to electrically connect the hard disk module and the second backplane 122. The second cable 140 may be used to electrically connect the function card module 130, which has a smaller size along the first direction X, and the backplane module 120. The second cable 140 may serve as a transfer between the function card module 130 and the backplane module 120.

[0138] Figure 18 A schematic diagram of the structure of the backplane module and fan module in the server provided in an embodiment of the present application; Figure 19 for Figure 18 Explosion diagram of Figure 20 This is a structural diagram of the fan module in the server provided in the embodiment of the present application from another angle. Figure 19 The first cable 124 is omitted to clearly illustrate the connector set 1233 .

[0139] See also Figures 18 to 20As shown, the server 100 also includes a fan module 150, which is arranged between the second backplane 122 and the second backplane 122; the fan module 150 includes multiple fans 151, and the fan 151 has a fifth connector 1511. The adapter board 123 has multiple connector groups 1233, and the connector groups 1233 are arranged one-to-one corresponding to the fifth connector 1511. Each connector group 1233 includes a sixth connector 1233a and a seventh connector 1233b, and the sixth connector 1233a and the seventh connector 1233b are rotationally symmetrical; the fifth connector 1511 is plugged into one of the sixth connector 1233a and the seventh connector 1233b.

[0140] A plurality of fans 151 can be mounted on the adapter plate 123. The plurality of fans 151 are arranged side by side along the second direction Y. Figures 18 to 20 Six fans 151 are shown in FIG. The airflow blown out by the fans 151 can flow along the first direction X to dissipate heat for the function card module 130 and the backplane module 120 .

[0141] When the backplane module 120 rotates relative to the housing 110, the fan module 150 also rotates with the rotation of the backplane module 120. However, when the computing devices 10 are arranged in the data center 1000, the airflow direction in each computing device 10 needs to be fixed. When the fan 151 rotates, the airflow direction of the fan 151 also changes. For example, before the backplane module 120 rotates, the airflow direction is from the first side 110a of the housing 110 to the second side 110b. After the backplane module 120 rotates, the airflow direction is from the second side 110b of the housing 110 to the first side 110a.

[0142] The embodiment of the present application solves this problem by providing a connector group 1233 on the adapter plate 123. Specifically, the connector group 1233 includes a sixth connector 1233a and a seventh connector 1233b. The rotational symmetry between the sixth connector 1233a and the seventh connector 1233b means that before the fan 151 rotates relative to the backplane module 120, the fifth connector 1511 on the fan 151 is aligned with and plugged into the sixth connector 1233a. After the fan 151 rotates relative to the backplane module 120, the fifth connector 1511 on the fan 151 is aligned with and plugged into the seventh connector 1233b.

[0143] Figure 21 A schematic diagram of the wind flow direction of the fan module in the server provided in an embodiment of the present application.

[0144] See also Figures 19 to 21As shown, before the backplane module 120 rotates, the fifth connector 1511 on the fan 151 is plugged into the sixth connector 1233a, and the sixth connector 1233a controls the rotation of the fan 151. The airflow direction F1 of the fan 151 blows from the first side 110a of the housing 110 to the second side 110b of the housing 110. After the entire backplane module 120 rotates 180° relative to the housing 110, the fan 151 is removed from the sixth connector 1233a and rotated 180° again, so that the fifth connector 1511 on the fan 151 is aligned and plugged into the seventh connector 1233b. The fan rotation is controlled by the seventh connector 1233b. Since the fan 151 has rotated two 180° degrees, it is equivalent to returning to its original position. The airflow direction F1 of the fan 151 still blows from the first side 110a of the housing 110 to the second side 110b of the housing 110.
