Description

Technical Field

[0001] This application relates to the field of server technology, and in particular to an electronic device. Background Technology

[0002] During the installation of the liquid-cooled GPU board, a blind-plug liquid-cooling connector is designed at the rear of the board. When the board is inserted downwards into the server chassis, the blind-plug liquid-cooling connector of the board and the liquid-cooling quick-connect connector of the chassis liquid distributor are matched and plugged in to realize the interconnection between the liquid in the liquid distributor and the liquid inside the board, thereby liquid cooling the GPU.

[0003] The dispenser is equipped with a spring. During insertion, the spring preload exerts an upward force on the circuit board. This force can easily cause the circuit board to misalign, damaging the gold fingers when inserting into the connector. This not only affects the installation efficiency of the circuit board but also increases hardware maintenance costs and reduces the reliability and stability of the system. Summary of the Invention

[0004] To address the aforementioned issues, this application provides an electronic device that ensures uniform stress distribution on the liquid-cooled circuit board module after installation, reducing the likelihood of the module tilting forward or backward, thereby effectively minimizing damage to the circuit board's gold fingers and improving the device's reliability.

[0005] This application provides an electronic device comprising a liquid-cooled plate module, a damping module, and a distributor module. The liquid-cooled plate module is located between the damping module and the distributor module, and is detachably connected to the damping module. The liquid-cooled plate module is also plugged into the distributor module. The damping module includes a first elastic component, and the distributor module includes a second elastic component. The first elastic component abuts against one end of the liquid-cooled plate module, and the second elastic component abuts against the other end of the liquid-cooled plate module. Both the first and second elastic components provide a thrust to the liquid-cooled plate module in a first direction, which is the insertion / removal direction of the liquid-cooled plate module.

[0006] In the above embodiments, the electronic device can specifically be a server, and the liquid-cooled board module is a GPU board module. The liquid-cooled board module and the distributor module are plugged into each other to achieve coolant exchange. The end where the damping module is located is the front end of the liquid-cooled board module, and the end where the distributor module is located is the rear end of the liquid-cooled board module. The first elastic component and the second elastic component provide support for the front and rear ends of the liquid-cooled board module, respectively, so that the forces at the front and rear ends of the liquid-cooled board module are balanced, reducing the possibility of the liquid-cooled board tilting forward and backward, and improving the reliability of the device.

[0007] In one embodiment, the liquid-cooled circuit board module includes at least one liquid-cooled circuit board assembly, which are arranged sequentially along a second direction perpendicular to the first direction. The liquid-cooled circuit board assembly includes a board body, a handle fixing member, and a fixing bracket. The board body includes a first side and a second side connected to each other. The handle fixing member is mounted on the first side, and the fixing bracket is mounted on the second side. A first latching assembly is provided at the end of the handle fixing member away from the fixing bracket. The first latching assembly is detachably connected to the damping module. The fixing bracket is provided with a second latching assembly. The first latching assembly enables the liquid-cooled circuit board assembly to be fixed and unlocked from the damping module, and the second latching assembly enables the liquid-cooled circuit board assembly to be fixed and unlocked from the central wall fixing member. This allows for screwless installation of the liquid-cooled circuit board assembly, improving assembly convenience.

[0008] In one embodiment, the electronic device further includes a central wall fastener, to which the second snap-fit ​​assembly is detachably connected. The central wall fastener includes a central wall body and a plurality of partition plates, which are spaced apart at the top of the central wall body along a second direction. Adjacent partition plates form receiving spaces, and each receiving space contains a guide pin extending along a first direction.

The central wall fastener is used to guide and limit the liquid-cooled circuit board assembly when it is inserted into the server chassis.

[0009] In one embodiment, the middle wall fastener further includes a limiting structure and a mounting guide groove. Both the limiting structure and the mounting guide groove are located within the receiving space formed by adjacent partition plates. The mounting guide groove is located between the limiting structure and one partition plate, and the limiting structure is located on the side of the guide pin. The limiting structure abuts against the rear-end fixing bracket when the liquid-cooled circuit board assembly is inserted, limiting the insertion depth of the circuit board body and preventing damage to the gold fingers from excessive insertion. The mounting guide groove guides the circuit board body vertically downwards into the bottom of the chassis.

[0010] In one embodiment, the damping module further includes a damping fixing member. The damping fixing member has a mounting groove on its side facing the liquid-cooled circuit board module. The first elastic component includes multiple torsion springs arranged along the extending direction of the damping fixing member. The damping fixing member also has multiple locking holes arranged along the extending direction of the damping fixing member. The damping module can provide an upward thrust to the front end of the liquid-cooled circuit board assembly, enabling force balance between the front and rear ends of the liquid-cooled circuit board assembly, and providing a fixed foundation for the liquid-cooled circuit board assembly, thereby ensuring secure installation of the liquid-cooled circuit board assembly.

[0011] In one embodiment, the first latching assembly includes a first latch and a first reset member. The first latch is rotatably mounted on the handle fixing member, and the first reset member is installed between the handle fixing member and the first latch. The first latch includes a first fixing part and a first hook part, and the first hook part engages with any one of the latch holes. The user can lock and unlock the liquid cooling plate assembly and the damping module by rotating the first latching assembly, achieving screwless assembly and disassembly. Furthermore, the first reset member enables the first latch to automatically reset, improving operational convenience.

[0012] In one embodiment, the second latching assembly includes a second latch and a second reset member. The second latch is rotatably mounted on a fixed bracket, and the second reset member is located between the fixed bracket and the second latch. The second latch includes a second fixing part and a second hook part. The electronic device also includes a central wall fixing member, which includes multiple partition plates. The second hook part engages with any one of the partition plates. The user can lock and unlock the liquid cooling plate assembly and the central wall fixing member by rotating the second latching assembly, achieving screwless assembly and disassembly. Furthermore, the second reset member enables the second latch to automatically reset, improving operational convenience.

[0013] In one embodiment, the handle fixing member has a slot at one end facing the damping module. The slot is used to engage with any one of the damping torsion springs of the first elastic component to reduce the slippage of the damping torsion spring when it is under force.

[0014] In one embodiment, the damping fixing member is provided with a limiting block, and the damping torsion spring abuts against the limiting block, the limiting block being used to restrict the rotation of the damping torsion spring.

[0015] In one embodiment, the electronic device further includes a chassis, a power supply board, and a base plate. The liquid-cooled plate module, the damping module, the liquid distributor module, the power supply board, and the base plate are all mounted in the chassis. The power supply board and the base plate are both mounted at the bottom of the chassis. The liquid-cooled plate module is plugged into the power supply board and the base plate. The power supply board supplies power to the liquid-cooled plate module, and the base plate transmits signals to the liquid-cooled plate module. Attached Figure Description

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description of the application is provided in conjunction with the accompanying drawings and embodiments.

[0036] The terminology used in the following embodiments is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” “the,” and “this” are intended to also include expressions such as “one or more” unless the context clearly indicates otherwise.

[0037] References to “an embodiment” or “a specific embodiment” as used in this specification mean that one or more embodiments of this application include a particular feature, structure, or characteristic described in connection with that embodiment. The terms “comprising,” “including,” “having,” and variations thereof mean “including, but not limited to,” unless otherwise specifically emphasized.

[0038] With the continuous development of computer technology, the performance of GPUs (Graphics Processing Units) is constantly improving, and the heat generated during their operation is also increasing dramatically. To ensure the stable operation of GPUs, liquid cooling technology is widely used for GPU board cooling. Liquid-cooled GPU boards have blind-plug liquid cooling connectors at the rear. During installation, the liquid-cooled board is inserted downwards into the server chassis, aligning with the quick-connect liquid cooling connectors of the chassis's distributor. This connects the coolant in the distributor with the liquid-cooled board, thereby providing liquid cooling for the GPU board.

[0039] In related technologies, a spring is installed inside the connector of a liquid-cooled distributor. Its main function is to provide continuous sealing pressure and vibration damping. The spring, through preload, ensures a tight fit between the sealing ring and the interface, maintaining a seal even under vibration or pressure fluctuations and preventing coolant leakage. The spring absorbs vibration energy during equipment operation, reducing the risk of connector loosening or detachment, and ensuring the stability and durability of the liquid cooling system. Some connectors allow the spring-energy-storing sealing ring to automatically compensate for axial misalignment during insertion and removal, adapting to sealing requirements under different operating conditions.

[0040] After the liquid cooling board is inserted into the distributor connector, the spring inside the liquid cooling connector continuously exerts an upward force on the board. Since this force point is located at the rear end of the liquid cooling board, uneven force distribution causes the board to tilt. This makes it difficult for the board's gold fingers to align accurately with the connector, potentially damaging the gold fingers. Furthermore, in related technologies, the positioning of the liquid cooling board is relatively simple, resulting in poor fixation and an inability to withstand spring force and vibration. This can cause displacement and loosening of the liquid cooling board, affecting the operation of the liquid cooling system.

[0041] In view of this, embodiments of this application provide an electronic device that ensures uniform stress on the liquid cooling board after installation, reduces the forward and backward tilting of the liquid cooling board, and improves the reliability of the device.

[0042] Figure 1 An assembly drawing of an electronic device provided for one embodiment of this application. Figure 2 An exploded view of an electronic device provided in one embodiment of this application, such as... Figure 1 Figure 2 As shown, an embodiment of this application provides an electronic device including a liquid-cooled circuit board module 1, a damping module 2, and a distributor module 5. The liquid-cooled circuit board module 1 is located between the damping module 2 and the distributor module 5. The liquid-cooled circuit board module 1 and the distributor module 5 are detachably plugged together, and the liquid-cooled circuit board module 1 and the damping module 2 are detachably connected. The damping module 2 includes a first elastic component, and the distributor module 5 includes a second elastic component. After the liquid-cooled circuit board module 1 and the damping module 2 are connected, one end of the liquid-cooled circuit board module 1 abuts against the first elastic component, which provides a thrust towards a first direction X. The other end of the liquid-cooled circuit board module 1 abuts against the second elastic component of the distributor module 5, which also provides a thrust towards the first direction X. The first direction X is the insertion / removal direction of the liquid-cooled circuit board module 1, i.e., the vertical direction in the figures.

[0043] In the above embodiments, the electronic device can specifically be a server, and the liquid-cooled board module 1 is a GPU board module. The liquid-cooled board module 1 and the distributor module 5 are connected to each other to achieve the communication of coolant. The end where the damping module 2 is located is the front end of the liquid-cooled board module 1, and the end where the distributor module 5 is located is the rear end of the liquid-cooled board module 1. The first elastic component and the second elastic component provide support for the front and rear ends of the liquid-cooled board module 1, respectively, so that the forces at the front and rear ends of the liquid-cooled board module 1 are balanced, reducing the tilting of the liquid-cooled board and improving the reliability of the device.

[0044] In one embodiment, the electronic device further includes a chassis 3, a power supply board 6, and a base plate 7. The liquid-cooled card module 1, the damping module 2, the liquid dispenser module 5, the power supply board 6, and the base plate 7 are all mounted on the chassis 3. Connectors are provided on the power supply board 6 and the base plate 7. Specifically, the power supply board 6 is provided with a power supply connector 601, and the base plate 7 is provided with a signal port 701. The power supply board 6 and the base plate 7 are both mounted on the bottom of the chassis 3, and the liquid-cooled card module 1 is plugged into the power supply board 6 and the base plate 7.

[0045] Figure 3 This is a structural diagram of a liquid-cooled board assembly provided in one embodiment of this application. Figure 4 This application provides a structural diagram of a liquid-cooled board assembly from another perspective, representing one embodiment of the present application. Figure 5 An exploded view of a liquid-cooled board assembly provided in one embodiment of this application. Figures 3-5 As shown, in one embodiment, the liquid-cooled circuit board module 1 includes at least one liquid-cooled circuit board assembly, which are arranged sequentially along a second direction Y, perpendicular to the first direction X. Each liquid-cooled circuit board assembly includes a board body 103, a handle fixing member 101, and a fixing bracket 102. The board body 103 includes a first side surface (top surface shown in the figure) and a second side surface (rear end surface shown in the figure) connected to each other. The handle fixing member 101 is mounted on the first side surface, and the fixing bracket 102 is disposed on the second side surface.

[0046] The board body 103 has a signal terminal 1031 and a power supply terminal 1032 on the side opposite to the handle fixing member 101. Specifically, the signal terminal 1031 can be an X16 signal gold finger, and the power supply terminal 1032 can be a power supply gold finger. The base plate 7 and the power supply board 6 are arranged sequentially along the third direction Z, with the base plate 7 near the front end and the power supply board 6 near the rear end. The signal terminal 1031 is plugged into the signal connector 701 of the base plate 7, and the power supply terminal 1032 is plugged into the power supply connector 601 of the power supply board 6. The signal connector 701 can be a PCIe X16 connector.

[0047] A first latching assembly 1012 is provided at the end (i.e., the front end) of the handle fixing member 101 away from the fixing bracket 102. The first latching assembly 1012 is detachably connected to the damping module 2 and is used to fix and separate the liquid cooling plate assembly from the damping module 2 located at the front end. A second latching assembly 1021 is provided at the top of the fixing bracket 102. The second latching assembly 1021 is used to fix and separate the liquid cooling plate assembly from the middle wall fixing member 4 located at the rear end (the middle wall fixing member 4 will be described in detail later).

[0048] In a further embodiment, the front end of the handle fixing member 101 has a mounting structure 1011, on which the first snap-fit ​​assembly 1012 is mounted. Along the first direction X, the mounting structure 1011 does not overlap with the board body 103; that is, the mounting structure 1011 extends towards and protrudes from the front end of the board body 103. An L-shaped mounting plate 1033 is provided on the front end face of the board body 103. The mounting structure 1011 is screwed to the L-shaped mounting plate 1033, thereby fixing the handle fixing member 101 to the board body 103 together. The mounting structure 1011 and the front end of the board body 103 form a right-angle region. This right-angle region is used to accommodate the damping module 2.

[0049] Figure 6 An assembly drawing showing the engagement of a damping torsion spring with a slot, as provided in one embodiment of this application, is shown below. Figures 3-6 In one embodiment, the handle retainer 101 has a slot 10111 at one end facing the damping module 2, the slot 10111 being located on the side of the handle retainer 101 facing away from the first latching assembly 1012. The first elastic assembly includes a plurality of damping torsion springs 202, and the slot 10111 is used to engage with any one of the damping torsion springs 202 of the first elastic assembly. Specifically, the slot 10111 is located at the bottom of the aforementioned mounting structure 1011. The damping torsion spring 202 includes two arms, and when the liquid-cooled plate clamping assembly is assembled with the damping module 2, the upper arm engages in the slot 10111.

[0050] When installing the liquid-cooled plate module 1, each liquid-cooled plate assembly is inserted into its mounting position one by one. Both the damping module 2 and the distributor module 5 have multiple mounting positions, with each mounting position corresponding to the installation of one liquid-cooled plate assembly.

[0051] To facilitate the insertion and removal of the liquid-cooled circuit board assembly, in a further embodiment, the handle retainer 101 includes two through holes 1013 arranged side-by-side along a third direction Z, with the through holes 1013 extending in the second direction Y. The through holes 1013 allow the operator's fingers to pass through, facilitating the insertion and removal of the liquid-cooled circuit board assembly. The through holes 1013 can be located in the upper middle part of the handle retainer 101, making it convenient for the user to grip and apply force, and ensuring force balance during insertion and removal of the liquid-cooled circuit board assembly. The third direction Z is the extending direction of the circuit board body 103. The aforementioned first direction X, second direction Y, and third direction Z are all perpendicular to each other.

[0052] Figure 7 This is a structural diagram of a wall fastener provided in one embodiment of this application. Figure 8 for Figure 7 A magnified view of the area circled in the middle. Figure 9 A partial enlarged view of the assembly of the guide pin and the positioning hole provided for one embodiment of this application, as shown below. Figures 7-9 As shown, in one embodiment, the electronic device further includes a central wall fixing member 4, which is located on the rear side of the liquid distributor module 5. The central wall fixing member 4 is mounted above the power supply board 6. The second snap-fit ​​assembly 1021 is detachably connected to the central wall fixing member 4. The central wall fixing member 4 is used to guide and limit the liquid cooling board assembly when it is inserted into the server chassis 3. Specifically, the central wall fixing member 4 includes a central wall body 401 and a plurality of partition plates 402. The plurality of partition plates 402 are spaced apart on the top of the central wall body 401 along the second direction Y. Two adjacent partition plates 402 form a receiving space, and each receiving space is a mounting position. One receiving space corresponds to the mounting position of a damping module 2 front and rear (along the third direction Y). Each receiving space is provided with a guide pin 403, which extends along the first direction X. The guide pin 403 can guide and position the liquid cooling board assembly when it is installed in the chassis 3. Correspondingly, the fixing bracket 102 of the liquid-cooled board assembly is provided with a positioning hole 1022, and the guide pin 403 passes through the positioning hole 1022 to complete the positioning of the liquid-cooled board assembly.

[0053] In a further embodiment, each partition plate 402 has a protrusion 4021 on the side facing the liquid-cooled plate assembly, and the protrusion 4021 is perpendicular to the partition plate 402. The protrusion 4021 is used to engage with the second snap-fit ​​assembly 1021, thereby fixing the liquid-cooled plate assembly to the central wall fastener 4.

[0054] In a further embodiment, the central wall fixing member 4 also has a limiting structure 404 and a mounting guide groove 405. Both the limiting structure 404 and the mounting guide groove 405 are located in the receiving space formed by two adjacent partition plates 402. The limiting structure 404 is located below the aforementioned protrusion 4021 and on the side of the guide pin 403, and is used to abut against the bottom of the rear fixing bracket 102 when the liquid-cooled board assembly is inserted, thereby limiting the insertion depth of the board body 103. The limiting structure 404 and the partition plate 402 on one side form the mounting guide groove 405. The extension direction of the mounting guide groove 405 is the first direction X, which can guide the board body 103 to be inserted vertically downward into the bottom of the chassis 3.

[0055] Figure 10 This is a structural diagram of a damping module provided in one embodiment of this application. Figure 11 An exploded view of a damping module provided in one embodiment of this application, as shown below. Figure 10 and Figure 11 As shown, in one embodiment, the damping module 2 further includes a damping fixing member 201. The damping fixing member 201 has a mounting groove 2012 on the side facing the liquid-cooled plate module 1. The first elastic component includes multiple damping torsion springs 202, which are arranged along the extending direction of the damping fixing member 201 and installed in the mounting groove 2012 by pins 203. The damping fixing member 201 also has multiple locking holes 2011, which are also arranged along the extending direction of the damping fixing member 201. Each mounting position of the damping module 2 corresponds to one locking hole 2011 and one damping torsion spring 202. The damping module 2 is fixedly installed on the front end of the chassis 3 via a connector 204. Specifically, the damping module 2 is fixedly installed between two opposite side walls of the chassis 3. After the damping module 2 is assembled with the chassis 3, the extending direction of the damping fixing member 201 is the second direction Y. Damping module 2 can provide an upward thrust to the front end of the liquid-cooled circuit board assembly, which balances the thrust provided by the second elastic component at the rear end. This allows the liquid-cooled circuit board assembly to be subjected to force balance at the front and rear ends, and also provides a fixed foundation for the liquid-cooled circuit board assembly, making the liquid-cooled circuit board assembly securely installed.

[0056] In a further embodiment, the damping fixing member 201 is provided with a limiting block 2013, which is located at the lower edge of the mounting groove 2012. The damping torsion spring 202 includes two arms, with the lower arm abutting against the limiting block 2013, which restricts the rotation of the damping torsion spring 202 when subjected to force.

[0057] Figure 12 A partial enlarged view of the first snap-fit ​​assembly and damping module provided in one embodiment of this application. Figure 13 This is a partially enlarged view of the assembly of the first snap-fit ​​component and the snap-hole according to an embodiment of this application. Figure 12 and Figure 13 As shown, in one embodiment, the first latching assembly 1012 includes a first latch 10121 and a first reset member (the first reset member is located inside the first latch 10121, not shown in the figure). The first latch 10121 is rotatably mounted on the mounting structure 1011 of the handle fixing member 101, and the first reset member is installed between the handle fixing member 101 and the first latch 10121. The first reset member can specifically be a torsion spring. The first latch 10121 includes a first fixing part and a first hook part that are connected to each other. The first fixing part is connected to the mounting structure 1011 through a rotating shaft, and the first hook part is engaged with any one of the latch holes 2011 of the damping fixing member 201.

[0058] In a further embodiment, the bottom end of the first hook has a slope. This slope serves as a guide; when the liquid cooling heat dissipation component is assembled onto the damping module 2, the first hook contacts the top surface of the damping fixing member 201, and under the guidance of the slope, the first buckle 10121... Figure 12 Rotating counterclockwise as shown opens the first latch 10121. When the liquid cooling plate assembly is inserted, the first hook inserts into the latch hole 2011 of the damping fixing member 201. At this time, the first latch 10121 rotates clockwise to reset under the push-back force of the first reset member, returning the first latch 10121 to the closed state, thus locking the liquid cooling plate assembly and the damping module 2. Pressing down on the first fixing part of the first latch 10121 and rotating it counterclockwise disengages the first hook from the latch hole 2011, unlocking the device.

[0059] Figure 14 A partially enlarged view of the assembly of the second snap-fit ​​component and the protrusion provided in one embodiment of this application, as shown below. Figure 14 As shown, in one embodiment, the second latching assembly 1021 may have the same structure as the first latching assembly 1012. Specifically, the second latching assembly 1021 includes a second latch 10211 and a second reset member (not shown in the figure). The second latch 10211 is rotatably mounted on the fixed bracket 102, and the second reset member is located between the fixed bracket 102 and the second latch 10211. The second latch 10211 includes a second fixing part and a second hook part that are connected to each other. The second fixing part is connected to the fixed bracket 102 via a rotating shaft, and the second hook part engages with the protrusion 4021 of any partition plate 402.

[0060] In a further embodiment, the bottom end of the second hook also has a bevel, which serves as a guide. When the liquid-cooled plate assembly is assembled onto the middle wall fastener 4, the second hook contacts the top surface of the protrusion 4021 on the partition plate 402 of the middle wall fastener 4. Under the guidance of the bevel, the second buckle 10211... Figure 14Rotating clockwise as shown opens the second latch 10211. When the liquid cooling plate assembly is inserted, the second latch 10211 rotates clockwise to reset under the return force of the second reset member. The second hook engages the bottom surface of the protrusion 4021, and the second latch 10211 returns to the closed state, completing the locking of the liquid cooling plate assembly to the central wall fixing member 4. Pressing down on the second fixing part of the second latch 10211 and rotating it clockwise disengages the first hook from the protrusion 4021 of the partition plate 402, completing the unlocking.

[0061] It is worth noting that the top of the aforementioned card hole 2011 and the bottom of the protrusion 4021 of the partition plate 402 are on the same horizontal plane within the allowable error range, so that the liquid cooling plate card assembly can remain horizontal after assembly, thereby maintaining a good plug-in state with the ports of the base plate 7 and the power supply plate 6, thereby improving the stability of power supply and signal transmission.

Figure 16 This is a partial enlarged view of a dispenser module provided in one embodiment of this application. Figure 17 This is an assembly drawing of a liquid-cooled plate assembly, a damping module, a distributor module, a central wall fixing component, a power supply board, a base plate, and a chassis, provided for one embodiment of this application. Figures 15-17 In one embodiment, the liquid distributor module 5 includes a plurality of liquid-cooled quick-connect fittings 501, which are spaced apart along a second direction Y and divided into two columns along a third direction Z. One column is the liquid inlet and the other is the liquid outlet. The liquid-cooled board assembly has two liquid-cooled quick-connect male ends 1034 arranged along the third direction Z, which are the liquid inlet and the liquid outlet, respectively. The liquid-cooled quick-connect male ends 1034 are inserted into the liquid-cooled quick-connect fittings 501. The second elastic component includes a plurality of springs 5011, and each liquid-cooled quick-connect fitting 501 has a spring 5011 that abuts against the liquid-cooled quick-connect male end 1034. During the pressing down of the liquid-cooled board module 1, each liquid-cooled board assembly generates an upward elastic force on the liquid-cooled quick-connect male end 1034 along the first direction X. The elastic force is approximately equal to the elastic force of the damping torsion spring 202 of the damping module 2, thereby balancing the forces on the front and rear ends of the liquid-cooled board assembly.
