Description

Technical Field

[0001] This invention relates to the field of cold plate installation and disassembly technology, and in particular to a cold plate installation and disassembly tooling structure and its usage method. Background Technology

[0002] With the continuous growth of data center computing demands and increasingly stringent energy efficiency requirements, the demand for liquid cooling radiators as a high-efficiency heat dissipation solution has increased significantly. Traditional air cooling methods can no longer meet the high requirements of high-performance servers for heat dissipation performance and noise control. Therefore, cold plate liquid-cooled servers have gradually become the mainstream in the market. These servers achieve efficient and quiet heat dissipation by directly circulating coolant to key heat-generating components inside the server, such as the CPU.

[0003] However, with the evolution of technology and the deepening of application requirements, the design of cold-plate liquid-cooled servers also faces new challenges. Currently, not only CPUs require cold plates for heat dissipation, but other high-performance components such as SDI (Serial Digital Interface) network cards, GPUs (Graphics Processing Units), and memory modules are also beginning to adopt cold-plate cooling technology to further optimize the overall system's thermal management efficiency. This trend necessitates the integration of three or more cold plates within the server, significantly increasing system complexity and maintenance difficulty. This makes it impossible for a single person to complete the installation of the entire cold plate system, impacting product repair / maintenance efficiency. Furthermore, if a cold plate falls into the chassis during installation, it can damage the product, posing a quality risk. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cold plate installation and disassembly fixture structure and its usage method.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] In a first aspect, embodiments of the present invention provide a cold plate installation and disassembly fixture structure, comprising: a base and a main body, the main body being placed on the base, the main body being provided with a positioning block, a gripping component and a spring clip, the main body being provided with a placement cavity for placing an SDI card cold plate and a mounting cavity for a liquid cooling connector, the spring clip being used to fix the SDI card cold plate and the liquid cooling connector, and the gripping component being used to fix a CPU cold plate.

[0007] In one specific embodiment, the gripping component includes a movable handle, a mounting end, and a gripping block. The mounting end is fixed to the main body, the movable handle is hinged to the mounting end, and the gripping block is drivenly connected to the movable handle. The gripping block is used to fix the CPU cold plate.

[0008] In one specific embodiment, the gripping block is provided with a self-locking screw, which is engaged with the CPU cold plate.

[0009] In one specific embodiment, there are two positioning blocks, which are respectively located on both sides of the bottom of the main body.

[0010] In one specific embodiment, the bottom of the positioning block is provided with a snap-fit ​​groove.

[0011] In one specific embodiment, the snap-fit ​​groove is further provided with a limiting protrusion.

[0012] In one specific embodiment, the positioning block is further provided with a pull pin.

[0013] In one specific embodiment, the liquid cooling connector is connected to the SDI card cold plate and the CPU cold plate via a liquid pipe.

[0014] In one specific embodiment, the base is provided with a support column, and the main body is provided with a support hole corresponding to the support column.

[0015] The advantages of the cold plate installation and disassembly fixture structure of the present invention compared with the prior art are as follows: the main body is fixed on the liquid-cooled server chassis, the gripping component picks up the CPU cold plate, and the spring clips fix the SDI card cold plate and the liquid cooling connector. After the entire set of cold plates is fixed on the main body, the main body is lifted and the entire set of cold plates is removed from the liquid-cooled server chassis. Then the main body is flipped and placed on the base, where operations such as applying thermal paste to the heat sink can be performed. After the product is repaired, the main body can be fixed back on the chassis, and the cold plates can be installed into the chassis one by one. This allows a single person to complete the installation and disassembly of the entire set of cold plates, improving the server's operation and maintenance efficiency and reducing the risk of collisions or product damage during the cold plate installation and disassembly process.

[0016] Secondly, embodiments of the present invention provide a method for using a cold plate installation and disassembly fixture structure, comprising the following steps:

[0017] Place the main body into the chassis and pull the pull pin to secure the main body to the chassis;

[0018] Lift the movable handle to allow the gripper block to descend and fit against the CPU cold plate, then tighten the non-removable screws to lock the gripper block into the CPU cold plate.

[0019] Loosen the screws between the CPU cooler and the motherboard, then press down the movable handle to detach the CPU cooler from the motherboard.

[0020] Remove the SDI card cold plate and place it in the placement cavity. Rotate the spring clip to fix the SDI card cold plate.

[0021] Remove the liquid cooling connector and place it in the mounting cavity. Rotate the spring clip to secure the liquid cooling connector.

[0022] Pull the pin to detach the main body from the chassis, then remove the main body and place it on the base to complete the disassembly of the SDI card cold plate and CPU cold plate.

[0023] The method of using the cold plate installation and disassembly fixture structure of the present invention has the following advantages compared with the prior art: The main body is fixed to the liquid-cooled server chassis by a pull pin. Then, the movable handle is lifted to allow the gripping block to descend and fit against the CPU cold plate. The non-detachable screws are then tightened to lock the gripping block and CPU cold plate. The screws between the CPU cold plate and the motherboard are then loosened. The movable handle is then pressed down to detach the CPU cold plate from the motherboard. The SDI card cold plate is removed and placed in the placement cavity. The spring clip is rotated to secure the SDI card cold plate. The liquid cooling connector is then removed and placed in the installation cavity. The spring clip is rotated to secure the liquid cooling connector. The pull pin is then pulled to detach the main body from the chassis. The main body is then removed and placed on the base to complete the disassembly of the SDI card cold plate and the CPU cold plate. Conversely, the installation of the SDI card cold plate and the CPU cold plate can also be achieved. This allows a single person to complete the installation and disassembly of the entire cold plate system, improving server maintenance efficiency and reducing the risk of collisions or product damage during cold plate installation and disassembly.

[0038] See Figures 1 to 4 The specific embodiment shown in the figure discloses a cold plate installation and disassembly fixture structure, including: a base 10 and a main body 20. The main body 20 is placed on the base 10. The main body 20 is provided with a positioning block 30, a gripping component 40 and a spring clip 50. The main body 20 is provided with a placement cavity for placing an SDI card cold plate 70 and a mounting cavity for a liquid cooling connector 80. The spring clip 50 is used to fix the SDI card cold plate 70 and the liquid cooling connector 80. The gripping component 40 is used to fix a CPU cold plate (not shown in the figure).

[0039] Specifically, the main body 20 is fixed to the liquid-cooled server chassis, the gripping component 40 picks up the CPU cold plate, and the spring clip 50 fixes the SDI card cold plate 70 and the liquid cooling connector 80. After the entire set of cold plates is fixed to the main body 20, the main body 20 is lifted and the entire set of cold plates is removed from the liquid-cooled server chassis. Then the main body 20 is flipped and placed on the base 10, where operations such as applying thermal paste to the heat sink can be performed. After the product is repaired, the main body 20 can be fixed back to the chassis (i.e., the liquid-cooled server chassis) and the cold plates can be installed into the chassis one by one. This allows a single person to complete the installation and removal of the entire set of cold plates, improving the server's operation and maintenance efficiency and reducing the risk of collisions or product damage during the installation and removal of cold plates. Furthermore, the main body 20 of the tooling structure, particularly its designed positioning block 30, gripping component 40, and spring clip 50, achieves stable fixation and convenient operation of the CPU cold plate, SDI card cold plate 70, and liquid cooling connector 80. This design allows maintenance personnel to complete the installation and removal of the entire cold plate system by a single person, significantly simplifying the operation process and reducing manpower requirements. Additionally, the spring clip 50 secures the SDI card cold plate 70 and liquid cooling connector 80, and ensures that the SDI card cold plate 70 and liquid cooling connector 80 will not fall off when the main body 20 is flipped. In other words, the ingenious design of the spring clip 50 and gripping component 40 ensures that the cold plates remain stable and do not fall off during installation and removal, preventing them from falling into the chassis due to improper operation, thereby effectively reducing the risk of product damage.

[0040] In one embodiment, the gripping assembly 40 includes a movable handle 41, a mounting end 42, and a gripping block 43. The mounting end 42 is fixed to the main body 20, the movable handle 41 is hinged to the mounting end 42, and the gripping block 43 is throttle connected to the movable handle 41. The gripping block 43 is used to fix the CPU cold plate.

[0041] Specifically, the mounting end 42 and the movable handle 41 are located on the upper surface of the main body 20, and the gripping block 43 is located on the lower surface of the main body 20. Lifting the movable handle 41 causes the gripping block 43 to move downward and fit against the CPU cold plate to fix the CPU cold plate; conversely, pressing down the movable handle 41 causes the gripping block 43 to move upward and detach from the CPU cold plate.

[0042] More specifically, the movable handle 41 is used to move the gripping block 43 up or down, and the position of the gripping block 43 can be adjusted on the X and Y axes so that the gripping block 43 is aligned with the screw holes of different CPU cold plates (AMD or Intel). The gripping block 43 is fixed to the CPU cold plate by a non-detachable screw, and a silicone block is provided to absorb the height difference between the gripping block 43 and the CPU cold plate.

[0043] In one embodiment, the gripping block 43 is provided with a self-locking screw, which engages with the CPU cold plate.

[0044] Specifically, when maintenance personnel lift the movable handle 41, the gripping block 43 descends and fits tightly against the CPU cold plate. At this point, tightening the captive screw secures the gripping block 43 to the CPU cold plate, ensuring its stability. This design effectively prevents the CPU cold plate from loosening and falling. When disassembling the CPU cold plate, maintenance personnel simply loosen the captive screw and press down the movable handle 41. The gripping block 43 then ascends and detaches from the CPU cold plate. This design simplifies and speeds up the installation and removal of the CPU cold plate, eliminating the need for complex tools or cumbersome operations and improving work efficiency. Furthermore, the precise design and transmission connection of the gripping block 43, along with the locking action of the captive screw, prevents unnecessary physical damage to the CPU cold plate or motherboard during installation and removal. This design reduces the risk of hardware damage due to improper operation and extends the server's lifespan.

[0045] In one embodiment, there are two positioning blocks 30, which are respectively located on both sides of the bottom of the main body 20.

[0046] Specifically, when the main body 20 is placed on the side wall of the liquid-cooled server chassis, it is fixed by two positioning blocks 30, which restrict the X-axis degree of freedom. That is, the two positioning blocks 30 are respectively located on both sides of the bottom of the main body 20. When the main body 20 is placed on the side wall of the liquid-cooled server chassis, these two positioning blocks 30 can effectively fix the main body 20 in place. This design ensures the stability of the main body 20 within the chassis, preventing it from loosening or shifting. In addition, the main function of the positioning blocks 30 is to restrict the X-axis degree of freedom of the main body 20. In physics, the degree of freedom refers to the number of directions in which an object can move freely in space. By restricting the X-axis degree of freedom, it is ensured that the main body 20 can only move or adjust along specific directions (such as the Y-axis or Z-axis) within the chassis, thereby avoiding unnecessary shaking or misalignment. In addition, since the positioning block 30 can precisely limit the position of the main body 20 in the X-axis direction, maintenance personnel can place the main body 20 more accurately in the predetermined position when installing it. This design improves the accuracy and efficiency of installation and reduces the risk of failure or performance degradation caused by improper installation.

[0047] In one embodiment, the bottom of the positioning block 30 is provided with a snap-fit ​​groove 31.

[0048] Specifically, the snap-fit ​​slot 31 engages with the side wall of the liquid-cooled server chassis, forming a robust mechanical connection. This connection effectively prevents the main body 20 from shaking or shifting within the chassis, ensuring its stability and reliability during operation. Furthermore, the snap-fit ​​mechanism between the slot 31 and the chassis side wall helps ensure precise alignment of the main body 20 during installation. Because the shape and size of the slot 31 are precisely designed, they fit tightly with corresponding parts on the chassis side wall, achieving high-precision installation.

[0049] In one embodiment, the snap-fit ​​groove 31 is further provided with a limiting protrusion 32.

[0050] Specifically, the limiting protrusion 32 cooperates with the limiting part provided on the liquid-cooled server chassis to restrict the Y-axis degree of freedom. In other words, the cooperation between the limiting protrusion 32 and the limiting part effectively prevents the main body 20 from wobbling or shifting in the Y-axis direction, ensuring the stability of the main body 20 within the chassis. Furthermore, the cooperation between the limiting protrusion 32 and the limiting part not only provides a secure connection but also ensures precise alignment of the main body 20 during installation, helping to avoid errors during the installation process.

[0051] In one embodiment, the positioning block 30 is further provided with a pull pin 60.

[0052] Specifically, the liquid-cooled server chassis has pin holes corresponding to the pull pin 60. The engagement of the pull pin 60 with these pin holes restricts the Z-axis degree of freedom. In other words, by engaging the pull pin 60 on the positioning block 30 with the pin holes on the chassis, the main body 20 can be fixed in the Z-axis direction. This, combined with the restrictions on the X and Y axes, achieves comprehensive fixation in three-dimensional space. Furthermore, the tight engagement of the pull pin 60 with the pin holes helps prevent wobbling or displacement of the main body 20 in the Z-axis direction, improving stability. Additionally, the design of the pull pin 60 typically simplifies installation and disassembly processes. Maintenance personnel can easily install or remove the main body 20 by simply inserting or removing the pull pin 60, without the need for complex tools or cumbersome operations.

[0053] In one embodiment, the liquid cooling connector 80 is connected to the SDI card cold plate 70 and the CPU cold plate via a liquid pipe.

[0054] Specifically, the liquid cooling connector 80, as a key component connecting the SDI card cold plate 70 and the CPU cold plate, circulates coolant to these two cold plates via liquid pipes. The coolant flows within the cold plates, absorbs heat, and then carries it away, achieving highly efficient heat dissipation. This method is more efficient than traditional air cooling, significantly reducing the operating temperature of the SDI card and CPU, improving their stability and lifespan. Furthermore, through the connection of the liquid cooling connector 80, the SDI card cold plate 70 and the CPU cold plate can form a unified cooling system. The coolant circulates within the system, helping to transfer heat from high-temperature areas (such as the CPU and SDI card) to low-temperature areas (such as heat sinks or external cooling devices), thus achieving temperature balance throughout the system. This helps prevent localized overheating and improves the overall performance and stability of the server. In addition, liquid cooling systems have higher energy efficiency than traditional air cooling systems. Due to the higher thermal conductivity of the coolant, liquid cooling systems can achieve the same cooling effect with lower energy consumption, which helps reduce server operating costs and minimize environmental impact.

[0055] In one embodiment, the base 10 is provided with a support column 11, and the main body 20 is provided with a support hole 21 corresponding to the support column 11.

[0056] Specifically, the main body 20 can be placed upright or upside down on the base 10. When placed upside down, the CPU cold plate faces upwards, allowing thermal grease to be applied to the bottom of the CPU cold plate. In other words, the cooperation between the support pillar 11 and the support hole 21 provides stable support for the main body 20. Whether placed upright or upside down, the main body 20 can be precisely positioned on the base 10 via the support pillar 11, preventing hardware damage or performance degradation caused by shaking or displacement. Furthermore, this design allows the main body 20 to be placed on the base 10 in two different ways (upright or upside down), providing flexibility for assembly and maintenance. For example, when placed upside down, the CPU cold plate faces upwards, making it easier for maintenance personnel to access the bottom of the CPU cold plate for convenient application of thermal grease or other maintenance work.

[0057] In this embodiment, two CPU cooling plates and one SDI card cooling plate 70 are included. The CPU cooling plates are located on the lower surface of the main body 20, and the SDI card cooling plate 70 is located on the upper surface of the main body 20. When the main body 20 is placed upright on the base 10, the SDI card cooling plate 70 faces upward; when the main body 20 is placed upside down on the base 10, the CPU cooling plates face upward.

[0058] Specifically, the spring snap fastener 50 uses existing publicly available technology, which will not be elaborated on here.

[0059] See Figure 5 As shown in the figure, an embodiment of the present invention provides a method for controlling the refrigeration heat recovery of a cold storage facility, comprising the following steps:

[0060] S1, place the main body 20 in the chassis and pull the pull pin 60 to fix the main body 20 to the chassis;

[0061] Specifically, by pulling the pin 60, the main body 20 can be quickly fixed to the chassis; similarly, by pulling the pin 60 again, the main body 20 can be easily detached from the chassis. This design greatly simplifies the installation and disassembly operations and improves work efficiency.

[0062] S2, lift the movable handle 41 to make the gripping block 43 move downward and fit against the CPU cold plate, then tighten the loose screw to lock the gripping block 43 and the CPU cold plate.

[0063] Specifically, lifting the movable handle 41 causes the gripper block 43 to descend and adhere to the CPU cold plate. By tightening the captive screws, the gripper block 43 and the CPU cold plate can be locked together. Similarly, lifting the movable handle 41 causes the gripper block 43 to descend and drive the CPU cold plate to adhere to the motherboard. Then, the screws between the CPU cold plate and the motherboard are tightened, the captive screws are loosened, and then the movable handle 41 is pressed down to disengage the gripper block 43 from the CPU cold plate.

[0064] S3, loosen the screws between the CPU cold plate and the motherboard, and then press down the movable handle 41 to detach the CPU cold plate from the motherboard.

[0065] Specifically, after tightening the screws to lock the gripping block 43 to the CPU cold plate, loosen the screws between the CPU cold plate and the motherboard, and then press down the movable handle 41 to make the gripping block 43 move upward to lift the CPU cold plate off the motherboard, that is, the CPU cold plate is lifted off the motherboard.

[0066] S4. Take out the SDI card cold plate 70 and place it in the placement cavity. Rotate the spring buckle 50 to fix the SDI card cold plate 70.

[0067] Specifically, loosen the screws securing the SDI card cooling plate 70 to the chassis, remove the SDI card cooling plate 70 and place it in the placement cavity, then rotate the spring clip 50 to secure the SDI card cooling plate 70. Similarly, rotate the spring clip 50, remove the SDI card cooling plate 70 and place it in the chassis, then tighten the screws to secure the SDI card cooling plate 70 to the chassis.

[0068] S5, take out the liquid cooling connector 80 and place it in the mounting cavity, and rotate the spring clip 50 to fix the liquid cooling connector 80;

[0069] Specifically, loosen the screws on the liquid cooling connector 80 from the chassis, remove the liquid cooling connector 80 and place it in the mounting cavity, then rotate the spring clip 50 to secure the liquid cooling connector 80. Similarly, rotate the spring clip 50, remove the liquid cooling connector 80 and place it in the chassis, then tighten the screws to secure the liquid cooling connector 80 to the chassis.

[0070] S6, pull the pull pin 60 to detach the main body 20 from the chassis, then remove the main body 20 and place it on the base 10 to complete the disassembly of the SDI card cold plate 70 and the CPU cold plate.

[0071] Specifically, once the entire cold plate is fixed to the main body 20, pull the pull pin 60 to detach the main body 20 from the chassis. Then, remove the main body 20 and place it on the base 10 to complete the disassembly of the SDI card cold plate 70 and the CPU cold plate. After the product repair is completed, fix the main body 20 to the chassis and install the entire cold plate into the chassis in sequence.

[0072] More specifically, the main body 20 is fixed to the liquid-cooled server chassis by the pull pin 60. Then, the movable handle 41 is lifted to allow the gripping block 43 to descend and fit against the CPU cold plate. The loose screws are then tightened to lock the gripping block 43 to the CPU cold plate. The screws between the CPU cold plate and the motherboard are then loosened. The movable handle 41 is then pressed down to detach the CPU cold plate from the motherboard. The SDI card cold plate 70 is then removed and placed in the placement cavity. The spring clip 50 is rotated to secure the SDI card cold plate 70. Finally, the liquid cooling connector is... Remove the head 80 and place it in the mounting cavity. Rotate the spring clip 50 to fix the liquid cooling connector 80. Then pull the pull pin 60 to detach the main body 20 from the chassis. Then remove the main body 20 and place it on the base 10 to complete the disassembly of the SDI card cold plate 70 and the CPU cold plate. Conversely, the SDI card cold plate 70 and the CPU cold plate can also be installed. This allows a single person to complete the installation and disassembly of the entire set of cold plates, improving the server's operation and maintenance efficiency and reducing the risk of collisions or product damage during the disassembly and assembly of the cold plates.
