[0042] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0043] As mentioned in the background technology, existing servers are generally installed in a small space. When the server is running for a long time, the electrical components will generate heat. Failure to dissipate heat in time will affect the operating efficiency of the server. Therefore, a heat dissipation structure is generally configured on the server to dissipate heat from the electrical components. In the prior art, servers generally use two heat dissipation modes: air cooling and water cooling. Depending on the operating environment, air cooling or water cooling is selectively used. However, when the server changes its operating environment, for example, when the air cooling mode needs to be switched to the water cooling mode, the water cooling mode requires components such as cooling pipes, and the server cannot be compatible with the various components used for water cooling, which affects the heat dissipation effect of the server. Therefore, in view of the above technical problems, the server rear window structure provided by the present application includes a casing 100, a first frame 200, a second frame 300, a water cooling module 400 and a first bracket 500, the water cooling module 400 is arranged on the casing 100, the first bracket 500 is arranged between the first frame 200 and the second frame 300, the first bracket 500 is arranged on the avoidance portion 510, and the refrigerant circulation pipe 410 in the water cooling module 400 extends out of the casing 100 through the avoidance portion 510, thereby participating in the circulation heat dissipation, so that With the support and avoidance of the first bracket 500, the refrigerant circulation pipe 410 can realize the heat dissipation function of the casing 100. In addition, the power module 210 in the first frame 200 and the fan module 310 in the second frame 300 can be directly connected by wires, so that the air cooling mode and the water cooling mode complement each other. At the same time, the gap between the first frame 200 and the second frame 300 is used to install the first bracket 500, which can also make the overall structure more compact, thereby realizing the compatibility of the server with different heat dissipation modes.

[0044] Please refer to Figures 1 to 16 The present application provides a server rear window structure, including: a casing 100; a first frame 200, which is arranged on the casing 100 and is used to install a power module 210; a second frame 300, which is arranged on the casing 100 and is used to install a fan module 310, and at least a portion of the first frame 200 is spaced apart from the second frame 300; a water cooling module 400, which is arranged on the casing 100, and the water cooling module 400 includes a refrigerant circulation pipe 410; a first bracket 500, which is arranged between the first frame 200 and the second frame 300, and the first bracket 500 is detachably connected to the first frame 200 and / or the second frame 300, and an avoidance portion 510 is arranged on the first bracket 500, and the refrigerant circulation pipe 410 extends out of the casing 100 through the avoidance portion 510.

[0045] According to the server rear window structure provided in the present application, it includes a casing 100, a first frame 200, a second frame 300, a water cooling module 400 and a first bracket 500. The first frame 200 is arranged on the casing 100 for installing a power module 210; the second frame 300 is arranged on the casing 100 for installing a fan module 310, and at least a part of the first frame 200 is spaced apart from the second frame 300; the water cooling module 400 is arranged on the casing 100, and the water cooling module 400 includes a refrigerant circulation pipe 410; the first bracket 500 is arranged between the first frame 200 and the second frame 300, and the first bracket 500 is detachably connected to the first frame 200 and / or the second frame 300, and an avoidance portion 510 is arranged on the first bracket 500, and the refrigerant circulation pipe 410 extends out of the casing 100 through the avoidance portion 510. By setting up the first bracket 500, and the first bracket 500 is detachably connected to the first frame 200 and / or the second frame 300, it is convenient to replace the first bracket 500. At the same time, an avoidance portion 510 is set on the first bracket 500 to avoid the refrigerant circulation pipe 410, so that the refrigerant circulation pipe 410 can be extended from the casing 100 to participate in the refrigerant circulation. When air cooling is required, the power module 210 can be connected to the fan module 310 to start air cooling. When water cooling is required, the water cooling module 400 is turned on and the refrigerant in the refrigerant circulation pipe 410 dissipates heat for the casing 100. In this way, the server can flexibly switch between air cooling and water cooling to meet operations with different heat dissipation requirements, thereby improving the compatibility of the server rear window structure with different heat dissipation modes.

[0046] Specifically, Fig.12 and Fig.13 As shown, the server rear window structure also includes: a wire management component 600, on which a first clamping portion 610 and a second clamping portion 620 are provided, the first clamping portion 610 is used to clamp the refrigerant circulation pipe 410, and the second clamping portion 620 is used to clamp the connecting wire, and the connecting wire is used to connect the power module and the fan module.

[0047] By providing the wire management component 600, it is helpful to organize and limit the refrigerant circulation pipe 410 and the connecting wires, optimize the line layout in the rear window structure, avoid mutual interference between the refrigerant circulation pipe 410 and the connecting wires, and be safer when switching between air cooling and water cooling.

[0048] In another embodiment provided in the present application, Figures 14 to 16As shown, the server rear window structure also includes: a second bracket 700, which can be selectively arranged with the first bracket 500 between the first frame 200 and the second frame 300; when the fan module 310 is running, the second bracket 700 is arranged between the first frame 200 and the second frame 300 to block the gap between the first frame 200 and the second frame 300. In the actual operation process, when the air cooling mode is adopted, the first bracket 500 and the water cooling module 400 can be removed, and the second bracket 700 can be installed between the first frame 200 and the second frame 300 to block the gap between the two. When the water cooling mode is adopted, the second bracket 700 is removed, the water cooling module 400 is installed in the casing 100, and the first bracket 500 is installed between the first frame 200 and the second frame 300, so as to avoid the refrigerant circulation pipe 410. In this way, when the heat dissipation mode of the server is changed according to the actual operating environment, the water cooling module 400 and the first bracket 5 00 matching setting, the water cooling module 400 and the first bracket 500 can be directly installed in the corresponding positions, and there is no need to separately set the layout of the refrigerant circulation pipe 410. The interval between the first frame 200 and the second frame 300 provides an installation space for installing the first bracket 500, and the widths of the first bracket 500 and the second bracket 700 are set to be the same. This avoids the situation where the width of the first bracket 500 or the second bracket 700 does not match the distance between the first frame 200 and the second frame 300 during the replacement process, resulting in the problem that the first bracket 500 or the second bracket 700 cannot be fixed.

[0049] The fan module 310 includes a fan plate 320 and a fan. The fan is arranged in the second frame 300. The fan plate 320 is arranged on the housing 100 and connected to each fan to support each fan.

[0050] Specifically, Fig.16As shown, the second bracket 700 includes a second connecting body 710 and a third connecting body 720, the second connecting body 710 and the third connecting body 720 are connected to each other, and the extension direction of the second connecting body 710 is perpendicular to the extension direction of the third connecting body 720, the second connecting body 710 is provided with a third mounting hole 711 and a fourth mounting hole 712, the third mounting hole 711 is directly connected to the sixth connecting hole 2213 on the first frame 200 by a connecting screw, the fourth mounting hole 712 is connected to the first mounting hole 301 on the second frame 300 by a connecting screw, and the third connecting body 720 is provided with a fifth mounting hole 721, a sixth mounting hole 722 and a third fixing hole 713. The fifth mounting hole 721 is arranged opposite to the seventh mounting hole on the second connecting body 710. After the connecting screw passes through the seventh mounting hole and the fifth mounting hole 721, the second connecting body 710 is connected to the third connecting body 720. The sixth mounting hole 722 is arranged opposite to the first through hole structure of the second connecting part 222. After the connecting screw passes through the sixth mounting hole 722 and the first through hole, the third connecting body 720 is connected to the first frame 200. The second connecting part 222 also includes a first positioning part 2223. The first positioning part 2223 is a positioning pin, and the third positioning part 723 is a positioning groove. The positioning groove is engaged with the positioning pin to realize the positioning of the second bracket 700.

[0051] In the specific implementation process, Figure 3 and Figure 4 As shown, the first frame 200 includes a first side surface 220, at least a portion of the first side surface 220 is opposite to the second frame 300; a first connecting portion 221 is provided on the first side surface 220, and the wire management component 600 is connected to the first connecting portion 221; a second connecting portion 222 is also provided on the first side surface 220, and at least a portion of the first bracket 500 is connected to the second connecting portion 222; wherein the second connecting portion 222 is bent from the first side surface 220 toward the second frame 300. This arrangement enables the wire management component 600 and the first bracket 500 to be located on the same side of the first frame 200, and when the refrigerant circulation pipe 410 passes through the first clamping portion 610, it can extend into the avoidance portion 510, thereby avoiding the bending of the refrigerant circulation pipe 410 to cause stress concentration, and at the same time, the first connecting portion 221 and the second connecting portion 222 are used to facilitate the fixing of the wire management component 600 and the first bracket 500.

[0052] The first frame 200 is also provided with a first locking member 201, which is a hand screw on the board. The first locking member 201 passes through the power backplane in the power module 210 and is connected to the first frame 200 to fix the power backplane. The first frame 200 is also provided with a power stop groove 202, and there are multiple power stop grooves 202. The multiple power stop grooves 202 extend along the height direction of the first frame 200. The first frame 200 is also provided with a housing fixing member 203, and the housing fixing member 203 has a plurality of housing stop grooves 202. 3 is a fixing screw hole, and the first frame 200 is riveted to the bottom and side of the housing 100 through the fixing screw holes. The first frame 200 is also provided with a hook 204 and a third connecting portion 205. The hook 204 is provided at one end of the first frame 200 close to the power backplane, and the hook 204 cooperates with the opening on the power backplane to achieve the positioning of the power backplane 211. The third connecting portion 205 includes a screw hole, and the onboard hand screw passes through the power backplane 211 and then enters the screw hole to achieve the fixing of the power backplane 211.

[0053] Specifically, Fig.12 and Fig.13 As shown, the cable management component 600 includes: a first mounting body 630, the first mounting body 630 is connected to the housing 100; a clamping member 640, the clamping member 640 is arranged on the first mounting body 630 and is spaced apart from the first mounting body 630, the clamping member 640 can be elastically arranged, the first clamping portion 610 is arranged between the clamping member 640 and the first mounting body 630, the first clamping portion 610 is arranged opposite to the avoidance portion 510, and at least a portion of the refrigerant circulation pipe 410 passes through the first clamping portion 610 and then passes through the avoidance portion 510.

[0054] Among them, the clamping member 640 extends along the height direction of the first mounting body 630, and the clamping member 640 can be flexibly arranged. When clamping the refrigerant circulation pipe 410, the clamping force on the refrigerant circulation pipe 410 can be increased under the action of the elastic restoring force to prevent the refrigerant circulation pipe 410 from moving. In addition, the first clamping portion 610 and the avoidance portion 510 are arranged relative to each other, which optimizes the layout path of the refrigerant circulation pipe 410.

[0055] Further, the first clamping portion 610 includes a clamping space 611, and the cable management component 600 further includes: a second mounting body 650, which is arranged opposite to and spaced from the first mounting body 630; and a third mounting body 660, wherein both ends of the third mounting body 660 are respectively connected to the first mounting body 630 and the second mounting body 650, so as to form a through opening 661 between the first mounting body 630, the second mounting body 650 and the third mounting body 660, and the through opening 661 is connected with the clamping space 611, and the refrigerant circulation pipe 410 passes through the through opening 661 and then penetrates into the clamping space 611. In order to further guide and limit the refrigerant circulation pipe 410, a more complex pipe fixing path is formed through the communication between the opening 661 and the clamping space 611. The refrigerant circulation pipe 410 first passes through the opening 661 and then enters the clamping space 611. This design can not only fix the pipe more firmly to prevent it from being displaced or damaged during the operation or transportation of the server, but also plays a better protective role, avoiding the pipe from being directly exposed to the internal environment of the server, reducing the risk of wear and collision. The space enclosed by the first mounting body 630, the second mounting body 650 and the third mounting body 660 provides more precise control for cable management. This design can effectively isolate different types of cables and pipes to avoid entanglement between them, thereby improving the neatness and maintainability of the server; the effective fixation and path management of the refrigerant circulation pipe 410 helps to optimize the flow path of the water cooling system, thereby improving the heat dissipation efficiency, especially for high-density, high-performance servers.

[0056] In order to facilitate the limiting of the connecting wire, the second clamping part 620 includes a limiting groove 621, and the wire management component 600 also includes: a limiting plate 670, which is arranged on the side of the second mounting body 650 away from the first mounting body 630, the limiting plate 670 and the second mounting body 650 are arranged at intervals, and the limiting groove 621 is arranged between the limiting plate 670 and the second mounting body 650. The limiting plate 670 is arranged on the side of the second mounting body 650 away from the first mounting body 630, so that the connecting wire in the limiting groove 621 and the refrigerant circulation pipe 410 passing through the opening 661 are separated in space, and the layout of the cables and pipes is effectively managed.

[0057] Specifically, the first connection portion 221 also includes a first connection flange 2210, a rivet nut 2211, a first mounting nail 2212 and a sixth connection hole 2213, the first connection flange 2210 is folded from the first side surface 220 toward the middle of the housing 100, the second mounting body 650 is provided with a third connection flange 652, the third connection flange 652 is folded from the second mounting body 650 toward the direction close to the first side surface 220, the first connection flange 2210 is attached to the third connection flange 652 and is locked by screws, and the bottom of the first mounting body 630 is provided with a fourth positioning portion 632, the fourth positioning portion 632 is provided. The first mounting body 630 has a fifth positioning portion 633 on its top, which is a second positioning portion 633. The first mounting body 630 has a second positioning portion 633 on its top, which is a second positioning portion 633. The first side 220 has a second mounting nail on its top, which is engaged with the second mounting nail to position the first mounting body 630. The second mounting body 650 has a second locking member 651 on its bottom, which is a hand screw. The first side 220 has a threaded hole opposite to the hand screw. The hand screw is inserted into the threaded hole to connect the second mounting body 650 to the first frame 200. The second mounting body 650 has a positioning through hole on its bottom, and the housing 100 has a guide pin 104 on its bottom, which is inserted into the positioning through hole to guide the cable management component 600 during installation.

[0065] In the embodiment provided in the present application, a temperature sensor and a pressure sensor are embedded in the cable management component 600, and the temperature sensor and the pressure sensor are respectively attached to the refrigerant circulation pipe 410. Each sensor continuously monitors the status of the cables and water pipes, including temperature, pressure and vibration, and the detection data is transmitted to the microprocessor in real time. The microprocessor analyzes the health status of the cables and water pipes and their impact on the heat dissipation efficiency of the server based on the received data. When the sensor detects an abnormal state (such as excessive cable temperature, abnormal water pipe pressure or excessive vibration), the microprocessor triggers an early warning mechanism and sends an alarm message to the server management system or maintenance personnel through the communication module so that timely measures can be taken.

During the adjustment process, the position sensor and the force feedback sensor continuously monitor, and once a potential problem is found (such as the fixing clip fails to fix the cable correctly), it will immediately feedback to the microprocessor, and the microprocessor will adjust the action or suspend the execution immediately to ensure the safety of the adjustment process. The mechanical arm adopts lightweight materials to ensure the rapid response and high stability of the mechanical arm. The joint motor adopts a stepper motor to achieve high-precision position control. In this way, the layout of the water pipes is automatically adjusted, manual intervention is reduced, and the efficiency of server management is improved.
