Abstract

The embodiment of the application provides a cold plate dismounting structure and electronic equipment, and relates to the technical field of cold plate dismounting. The cold plate dismounting structure comprises a dismounting assembly and at least two cold plate assemblies. The dismounting assembly is matched with a guide piece and a first mounting piece on the cold plate assembly through a connecting piece. Each connecting piece corresponds to one cold plate assembly. The connecting piece has two working positions, i.e., a locking position and a dismounting position. When the connecting piece is in the locking position, the connecting piece can be connected with the matched end of the first mounting piece, so that the cold plate and the dismounting assembly are fixed. At this time, an operator can simultaneously pick up the at least two cold plate assemblies through the dismounting assembly to move and position the cold plate assemblies. When the connecting piece is in the intermediate position, the connecting piece is detachably connected with the guide piece, so that the connecting piece can be switched to the locking position or the dismounting position. When the connecting piece is in the dismounting position, the connecting piece can be separated from the guide piece, so that the operator can take down the dismounting assembly from the cold plate assembly, thereby avoiding space occupation.

Description

Technical Field

[0001] This application relates to the field of cold plate assembly and disassembly technology, and in particular to a cold plate assembly and disassembly structure and electronic equipment. Background Technology

[0002] With the development of information technology, the power density and heat generation of central processing units (CPUs) and memory in electronic devices are increasing daily. To ensure the stable operation of electronic devices under high loads and prevent performance degradation or damage due to overheating, current technologies typically involve directly attaching liquid cooling radiators (cold plates) to the surface of the CPU and memory chips, utilizing the circulating flow of coolant in the internal channels to dissipate heat.

[0003] In practical applications, since electronic devices typically integrate multiple CPUs and memory modules, multiple cold plates need to be connected in series or parallel through pipes and fixed to the main board of the electronic device with screws.

[0004] However, when installing or removing cold plates, operators need to use one hand to hold the cold plate and align it with the mounting holes, while using the other hand to lock it in place. When installing multiple cold plates, this process must be repeated one by one, resulting in low efficiency in cold plate assembly and maintenance. Utility Model Content

[0005] This application provides a cold plate disassembly and assembly structure and electronic equipment to solve the problem of low efficiency in the assembly and maintenance of disassembled cold plates.

[0006] In a first aspect, embodiments of this application provide a cold plate disassembly and assembly structure, including:

[0007] At least two cold plate assemblies, each cold plate assembly including a cold plate, a guide member, and a first mounting member; the cold plate is disposed on the component to be scald to dissipate heat from the component, and the cold plate has a first mounting portion on the side opposite to the component to be scald; the guide member is disposed on the side of the first mounting portion opposite to the component to be scald, and the first mounting member passes through and is connected to the first mounting portion; the top of the first mounting member also has a mating end, and the guide member can move relative to the first mounting member to move closer to or away from the mating end;

[0008] The assembly includes a disassembly component and at least two connectors. The connectors are located on one side of the disassembly component and are movably connected to it. Each connector corresponds to one of the cold plate assemblies. When the disassembly component is located on the side of the cold plate away from the circuit board, the connectors are close to the cold plate and can move relative to the cold plate so that the connectors have a locking position and a disassembly position relative to the cold plate.

[0009] When the connector is in the locked position, the connector and the mating end are detachably connected;

[0010] When the connector is in the disassembled position, the connector rotates to the side away from the guide so that the connector can be disengaged from the guide and the mating end.

[0011] In one possible implementation, the connector also has an intermediate position relative to the cold plate. The connector is configured to be movable to the intermediate position when the disassembly component moves toward the side facing the cold plate. When the connector is in the intermediate position, the connector is detachably connected to the guide. The connector is also configured to be movable to a disassembly position when the disassembly component moves toward the side away from the cold plate.

[0012] In one possible implementation, the end of the connector facing the cold plate is the connecting end, and when the connector is in the locked position, the connecting end and the mating end are engaged with the side of the guide member facing the guide member.

[0013] The connecting end has a mating surface on the side facing the guide member, and the guide member has a first guide surface on the side facing the mating end. The first guide surface is configured to mate with the mating surface to guide the connecting end to move toward one side of the cold plate.

[0014] In one possible implementation, the guide has a second guide surface on the side facing the cold plate;

[0015] When the connector is in the middle position, the connecting end abuts against the second guide surface. The connecting end is configured to drive the guide to move towards the mating end as the disassembly / assembly part moves toward the side away from the cold plate, so that the connector moves to the disassembly position.

[0016] In one possible implementation, the mating end has a receiving cavity at the end facing the guide member, and when the connector is in the disassembled position, at least part of the guide member is located in the receiving cavity;

[0017] And / or, when the connector is in the locked position, the first mounting part is supported on the side of the guide that is away from the mating end.

[0018] In one possible implementation, the assembly / disassembly component includes a main body and a first fixing part, with a connector movably connected to the main body; the first fixing part is located on one side of the main body, and a connector is provided on each of the opposite sides of the first fixing part, with a through-hole provided at each position corresponding to the two connectors.

[0019] When the connector is in the locked position, the mating end is located inside the first fixed part, and both connectors pass through their respective through holes and can be detachably connected to the mating end at the same time.

[0020] In one possible implementation, the cold plate also has a second mounting portion on the side away from the heat dissipation component, and the second mounting portion has a first mating portion and a second mating portion that are interconnected.

[0021] The cold plate assembly also includes a locking unit, which is located on the same side of the cold plate as the second mounting part, and the locking unit has a locking part;

[0022] When the connector is in the locked position, the locking part engages with the first mating part;

[0023] When the connector is in the disassembled position, the locking part engages with the second mating part, and when the disassembled part moves toward the side away from the cold plate, the locking part can disengage from the second mating part.

[0024] In one possible implementation, the locking unit includes a locking member and an elastic member. The elastic member is sleeved on the circumferential outer side of the cold plate in the second mounting portion, and the locking member is located at the end of the elastic member away from the cold plate. The side of the locking member facing the second mounting portion has a locking portion.

[0025] The first mating part is a first groove, and the second mating part is a second groove. The second groove extends to the end face of the second mounting part away from the cold plate. The mounting part also has a connecting groove, through which the first groove communicates with the second groove.

[0026] When the connector is in the locked position, at least part of the locking part is located in the first groove; during the process of switching the connector from the intermediate position to the locked position, the locking part moves to the second groove through the connecting groove.

[0027] In one possible implementation, the detachable component further includes a second fixing part. When the connector is in the locked position, a portion of the second mounting part is located inside the second fixing part, and the second fixing part is pressed against the end of the locking member away from the elastic member.

[0028] In one possible implementation, the connector further includes a through portion; the disassembly assembly further includes a connecting shaft and a reset member, the connecting shaft passing through the through portion and mounted on the disassembly assembly so that the connector can rotate about the connecting shaft.

[0029] The reset piece is sleeved on the circumferential outer side of the connecting shaft, with one end of the reset piece connected to the disassembly / assembly part and the other end of the reset piece connected to the connecting part.

The assembly / disassembly component engages with guides and first mounting components on the cold plate assemblies via connectors. Each connector corresponds to one cold plate assembly and has two working positions: a locking position and a disassembly position. When the connector is in the locking position, it connects to the mating end of the first mounting component, fixing the cold plate to the assembly / disassembly component. At this time, the operator can simultaneously pick up at least two cold plate assemblies for overall movement and positioning using the assembly / disassembly component. When the connector is in the disassembly position, it detaches from the guides, allowing the operator to remove the assembly / disassembly component from the cold plate assembly, avoiding space occupation. By adopting the cold plate assembly / disassembly structure provided in this application, multiple cold plates can be quickly installed, improving assembly / disassembly efficiency.

[0062] Unless otherwise stated, the term "multiple" means two or more.

[0063] With the development of information technology, the power density and heat generation of central processing units (CPUs) and memory in electronic devices are increasing daily. To ensure the stable operation of electronic devices under high loads and prevent performance degradation or damage due to overheating, current technologies typically involve directly attaching liquid cooling radiators (cold plates) to the surface of the CPU and memory chips, utilizing the circulating flow of coolant in the internal channels to dissipate heat.

[0064] In practical applications, since electronic devices typically integrate multiple CPUs and memory modules, multiple cold plates need to be connected in series or parallel through pipes and fixed to the main board of the electronic device with screws.

[0065] However, when installing or removing cold plates, operators need to use one hand to hold the cold plate and align it with the mounting holes, while using the other hand to lock it in place. When installing multiple cold plates, this process must be repeated one by one, resulting in low efficiency in cold plate assembly and maintenance.

[0066] In view of this, the cold plate disassembly and assembly structure and electronic device provided in this application include a disassembly and assembly component and at least two cold plate assemblies. The disassembly and assembly component cooperates with a guide and a first mounting component on the cold plate assembly via a connector, and each connector corresponds to one cold plate assembly. The connector has two working positions: a locking position and a disassembly position. When the connector is in the locking position, it can connect with the mating end of the first mounting component to fix the cold plate to the disassembly and assembly component. At this time, the operator can simultaneously pick up at least two cold plate assemblies through the disassembly and assembly component for overall movement and positioning. When the connector is in the disassembly position, the connector can detach from the guide, allowing the operator to remove the disassembly and assembly component from the cold plate assembly, avoiding space occupation. By adopting the cold plate disassembly and assembly structure provided in this application, multiple cold plates can be quickly installed, improving disassembly and assembly efficiency.

[0067] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0068] Please refer to Figures 1 to 8 This embodiment provides a cold plate disassembly and assembly structure, including a disassembly and assembly component 200 and at least two cold plate components 100.

[0069] In this embodiment, a cold plate assembly is disposed on the component to be scald to dissipate heat. The cold plate assembly 100 includes a cold plate 110, which has cooling channels inside. Coolant can circulate within the cooling channels and exchange heat with the component to be scald in contact with the cold plate 110 to remove the heat generated by the component and achieve heat dissipation.

[0070] In this embodiment, the component to be cooled is a circuit board 10. The circuit board 10 is the motherboard of an electronic device, such as a computer motherboard.

[0071] In other embodiments, the component to be cooled can be other components that require heat dissipation. This embodiment does not impose any restrictions on this, and an adaptive selection can be made according to actual needs.

[0072] The following description uses circuit board 10 as the component to be cooled.

[0073] In this embodiment, there are at least two cold plate assemblies 100 to meet the heat dissipation requirements of the circuit board 10, thereby enhancing the heat dissipation effect of the cold plate assembly 100. The cold plates 110 are interconnected by cooling pipes, forming parallel or series coolant circulation paths. Driven by a circulation pump, the coolant flows through the cooling channels within each cold plate 110 to dissipate heat from the circuit board 10, ensuring that the circuit board 10 can maintain its normal operating temperature.

[0074] However, when the cold plate 110 needs to be disassembled for maintenance or replacement, since multiple cold plate assemblies 100 are interconnected, the cooling pipes connected to the cold plate 110 must first be disconnected to drain the coolant before the cold plate 110 can be removed from the circuit board 10. After maintenance, the cold plate 110 must be reinstalled onto the circuit board 10 and all cooling pipes must be reconnected, making the process cumbersome.

[0075] To maintain the connection between the cold plate assemblies 100 to avoid the cumbersome operations of draining and reconnecting the pipes, at least two operators are required to work together. One operator needs to hold up the cold plate assembly 100 with the cooling pipes, while the other operator performs the disassembly operation between the cold plate 110 and the circuit board 10, which results in high labor costs.

[0076] In view of this, the cold plate assembly 100 also includes a guide 120 and a first mounting member 130. The cold plate 110 has a first mounting portion 111 on the side away from the heat dissipation component. The guide 120 is located on the side of the first mounting portion 111 away from the circuit board 10. The first mounting member 130 passes through the first mounting portion 111 and is connected to the first mounting portion 111. The disassembly assembly 200 includes a disassembly member 210 and at least two connecting members 220. The connecting members 220 are located on one side of the disassembly member 210 and are movably connected to the disassembly member 210. Each connecting member 220 corresponds to each cold plate assembly 100. When the disassembly member 210 is located on the side of the cold plate 110 away from the circuit board 10, the connecting member 220 is close to the cold plate 110 and can move relative to the cold plate 110, so that the connecting member 220 has a locking position and a disassembly position relative to the cold plate 110.

[0077] In this embodiment, the first mounting part 111 has a mounting groove to accommodate the first mounting member 130, and the guide member 120 is sleeved on the first mounting member 130 to connect the guide member 120 to the first mounting part 111.

[0078] In some exemplary embodiments, the first mounting member 130 is a screw, the mounting groove is a threaded hole, and the first mounting member 130 is screwed into the mounting groove.

[0079] Specifically, when the connector 220 is in the locked position, it is detachably connected to the mating end 131. The connector 220 is configured to move to the middle position when the disassembly / assembly component 210 moves towards the cold plate 110. At this time, the operator can hold the disassembly / assembly component 210 with one hand. Since the connector 220 on the disassembly / assembly assembly 200 is connected to each cold plate 110, each cold plate assembly 100 can remain assembled, forming an integrated disassembly / assembly structure. The operator's other hand can perform installation, fixing, or disassembly operations between the circuit board 10 and the cold plate 110 without the need for assistance from other operators or disassembly of the cooling pipes between the cold plate assemblies 100. This greatly simplifies the disassembly operation of the cold plate assembly 100 and improves the efficiency of the disassembly / assembly work.

[0080] When it is necessary to disassemble the assembly 200, the connector 220 can be switched to the disassembly position. When the connector 220 is in the disassembly position, the connector 220 rotates away from the guide 120 so that the connector 220 can be separated from the guide 120 and the mating end 131. This allows the operator to separate the assembly 200 from the cold plate assembly 100. As a result, when the circuit board 10 is installed inside the electronic device, it does not occupy the internal space of the electronic device, which helps to improve the utilization rate of the internal space of the electronic device.

[0081] In this embodiment, no restrictions are placed on the installation method of the connector 220. For example, the connector 220 is installed on the disassembly part 210 by a pin and can rotate relative to the pin to move away from the first mounting part 130.

[0082] When the operator disassembles the assembly 200 and needs to reinstall it, they only need to connect the connector 220 to the first mounting component 130. No other additional tools are required, which can quickly connect the assembly 200 to the cold plate assembly 100 and simplify the repetitive installation process.

[0083] Please refer to Figures 1 to 8 In some embodiments, the connector 220 also has an intermediate position relative to the cold plate 110. The connector 220 is configured to be movable to the intermediate position when the disassembly member 210 moves toward the side of the cold plate 110. When the connector 220 is in the intermediate position, the connector 220 is detachably connected to the guide member 120. The connector 220 is also configured to be movable to the disassembly position when the disassembly member 210 moves toward the side away from the cold plate 110.

[0084] Specifically, in this embodiment, after the operator completes the disassembly or installation of the cold plate assembly 100, the disassembly / installation component 210 can be moved toward the cold plate 110 to allow the connector 220 to switch to the intermediate position. When the connector 220 is in the intermediate position, it is detachably connected to the guide component 120. The connector 220 is configured to move to the disassembly position when the disassembly / installation component 210 moves toward the side away from the cold plate 110. This intermediate position setting creates a transition between the locking position and the disassembly position, ensuring the stability of the cold plate assembly 100 during the disassembly / installation process. It also prevents the connector 220 from switching from the locking position to the disassembly position due to operator error, thus avoiding the cold plate assembly 100 from falling off. This achieves a smooth switching of the connector 220 between different working positions.

[0085] In this embodiment, the mounting part has a receiving groove that matches the connector 220. When the connector 220 is in the locked position and the intermediate position, the connector 220 can be inserted into the receiving groove, so that the connector 220 can be guided by the groove wall of the receiving groove, avoiding the operator from shifting when moving the disassembly and assembly part 210, causing the connector 220 to disengage from the cold plate assembly 100, so as to ensure the stability of the connector 220 when switching between different working positions.

[0086] It should be noted that since the connector 220 needs to pass through an intermediate position to switch from the locked position to the disassembly position, that is, the disassembly part 210 needs to be moved towards the cold plate 110 to bring the connector 220 to the intermediate position, and then the disassembly part 210 needs to be moved away from the cold plate 110 to switch to the disassembly position, even if the operator accidentally applies pressure to the disassembly part 210 towards the cold plate 110 during the disassembly process, the connector 220 will only switch from the locked position to the intermediate position, and will not switch directly to the disassembly position to disengage, thereby avoiding accidental unlocking caused by misoperation and improving the safety of the disassembly process.

[0087] Please refer to Figures 1 to 8 In some embodiments, the end of the connector 220 facing the cold plate 110 is the connecting end 221. When the connector 220 is in the locked position, the connecting end 221 and the mating end 131 are engaged with the side of the guide member 120 to ensure the stability of the connection between the connector 220 and the cold plate 110 and to prevent the cold plate assembly 100 from accidentally falling off during the disassembly and assembly of the cold plate assembly 100.

[0088] In this embodiment, when the connector 220 is in the locked position, the connecting end 221 can be engaged with the mating end 131 of the first mounting part 130 to ensure the stability of the connection between the connector 220 and the cold plate 110 and to prevent the cold plate assembly 100 from falling off during the disassembly and assembly of the cold plate assembly 100.

[0089] It should be noted that this embodiment does not limit the specific structural form of the connecting end 221 and the mating end 131. For example, the connecting end 221 can be implemented as a protruding locking block, and the mating end 131 can be provided with a corresponding locking groove; or the connecting end 221 can be an elastic buckle, and the mating end 131 can be provided with a locking edge. Those skilled in the art can select an appropriate locking form according to actual assembly requirements and space constraints. Any locking structure that can achieve axial locking should fall within the protection scope of this application.

[0090] In this embodiment, the connecting end 221 has a mating surface on the side facing the guide member 120, and the guide member 120 has a first guide surface 121 on the side facing the mating end 131. The first guide surface 121 is configured to mate with the mating surface to guide the connecting end 221 to move toward one side of the cold plate 110.

[0091] Specifically, in this embodiment, the first guide surface 121 is an inclined surface. When the operator presses down on the disassembly / assembly component 210 to move it toward the cold plate 110, the mating surface of the connecting end 221 will contact the first guide inclined surface of the guide component 120. Due to the guiding effect of the inclined surface, the connecting component 220 rotates away from the guide component 120 while continuing to move, thereby gradually disengaging the connecting end 221 from the mating end 131, allowing the connecting component 220 to switch to the intermediate position. Through the setting of the first guide surface 121 and the mating surface, the connecting component 220 can be smoothly guided from the locked position to the intermediate position, ensuring the accuracy and controllability of the switching of the connecting component 220 between different working positions.

[0092] Please refer to Figures 1 to 8 In some embodiments, the guide member 120 has a second guide surface 122 on the side facing the cold plate 110. When the connector 220 is in the intermediate position, the connecting end 221 abuts against the second guide surface 122. The connecting end 221 is configured to move the guide member 120 towards the mating end 131 as the disassembly member 210 moves towards the side away from the cold plate 110, thereby moving the connector 220 to the disassembly position. This allows the connecting end 221 to apply a force to the guide member 120 through the second guide surface 122 when the disassembly member 210 moves towards the side away from the cold plate 110, causing the guide member 120 to move along the first mounting member 130 towards the mating end 131, thus achieving a smooth transition from the intermediate position to the disassembly position. This design ensures the continuity and controllability of the workstation switching process and improves the convenience of operation.

[0093] Please refer to Figures 1 to 8In some embodiments, the first guide surface 121 and the second guide surface 122 are connected in an arc shape on the side opposite to the first mounting member 130. This allows the connecting end 221 to move along a continuous and smooth path during the switching process from the locked position to the intermediate position, avoiding movement jamming caused by sharp corners or steps. In addition, the arc-shaped connection structure can also reduce the frictional resistance when the connecting member 220 moves.

[0094] Please refer to Figures 1 to 8 In some embodiments, the mating end 131 has a receiving cavity 1311 at the end facing the guide 120, and when the connector 220 is in the disassembled position, at least a portion of the guide 120 is located within the receiving cavity 1311.

[0095] Specifically, in this embodiment, the receiving cavity 1311 is a groove structure formed at the lower part of the mating end 131, and the shape of the receiving cavity 1311 is matched with the upper contour of at least part of the guide member 120.

[0096] The second guide surface 122 can form a guide slope with the cavity wall of the accommodating cavity 1311. At this time, the operator continues to move the disassembly and assembly component 210 in the direction away from the cold plate 110. The connecting end 221 of the connector 220 can rotate in the direction away from the first mounting component 130 under the guidance of the second guide surface 122, so that the connector 220 is disengaged from the first guide component 120 and the first mounting component 130, thereby realizing the disassembly and assembly component 200.

[0097] In this embodiment, the second guide surface 122 is an inclined surface to generate a radial component force when the connector 220 moves, guiding the connector 220 to complete the rotation action.

[0098] It should be noted that this embodiment does not limit the tilt angle of the first guide surface 121 and the second guide surface 122, and can be adapted to meet actual needs. Furthermore, the tilt angles of the first guide surface 121 and the second guide surface 122 can be the same or different.

[0099] If the guide member 120 is not fully embedded in the receiving cavity 1311, causing the second guide surface 122 to be lower than the opening edge of the receiving cavity 1311, a stepped structure will be formed between the guide member 120 and the mating end 131. In this case, when the connector 220 moves away from the cold plate 110, the connecting end 221 rotates under the guidance of the second guide surface 122 and temporarily disengages from the snap-fit ​​state. However, when the connecting end 221 continues to move out of the range of the second guide surface 122, due to the obstruction of the stepped structure, the connecting end 221 cannot maintain the rotated state and will spring back to the initial state. At this time, the connecting end 221 of the connector 220 in the initial state will re-engage with the mating end 131, causing the connector 220 to unexpectedly return to the locked position, resulting in the failure of the disassembly operation.

[0100] Therefore, in this embodiment, the depth of the receiving cavity 1311 is set such that after the guide member 120 is inserted into the receiving cavity 1311, only the second guide surface 122 is exposed outside the receiving cavity 1311, and the outer edge of the second guide surface 122 is flush with the opening edge of the receiving cavity 1311, so that the connector 220 can rotate and disengage directly under the guidance of the second guide surface 122, ensuring the reliability and smoothness of the disassembly operation, while avoiding component damage or operation failure caused by motion interference.

[0101] When the connector 220 is in the locked position, the first mounting portion 111 is supported on the side of the guide 120 away from the mating end 131. When the connector 220 needs to be switched from the locked position to the disassembly position, the operator first moves the connector 220 to the middle position. At this time, the connecting end 221 is disengaged from the mating end 131 but is still engaged with the guide 120. Then the operator continues to move the disassembly part 210 to the disassembly position. The connector 220 drives the guide 120 to move together in the direction away from the cold plate 110, so that the guide 120 is disengaged from the support contact of the first mounting portion 111.

[0102] This ensures that the guide 120 is always supported by the first mounting part 111 when it is in the locked position, preventing vibration from causing the guide 120 to loosen.

[0103] Please refer to Figures 1 to 8 In some embodiments, the detachable component 210 includes a main body 211 and a first fixing part 212, with a connector 220 movably connected to the main body 211. The first fixing part 212 is located on one side of the main body 211, and a connector 220 is provided on each of its opposite sides. The first fixing part 212 has through holes at positions corresponding to the two connectors 220. When the connector 220 is in the locked position, the mating end 131 is located inside the first fixing part 212, and both connectors 220 pass through their respective through holes, allowing for detachable connection with the mating end 131.

[0104] In this embodiment, the first fixing part 212 is provided on one side of the main body part 211 for installing and fixing the connector 220, so as to provide a stable installation base for the connector 220.

[0105] The through-hole is slightly larger than the external dimensions of the connector 220 to provide clearance for movement. This allows the connector 220 appropriate freedom of movement within the through-hole, facilitating its rotation when switching between different working positions. When the connector 220 needs to switch from the locked position to the dismounted position, guided by the first guide surface 121 and the second guide surface 122, it can rotate within the space defined by the through-hole, releasing the engagement with the mating end 131 or the guide 120, and then moving axially to complete the position switch.

[0106] Please refer to Figures 1 to 8 In some embodiments, the cold plate 110 also has a second mounting portion 112 on the side opposite to the heat-dissipating component, and the second mounting portion 112 has a first mating portion 1121 and a second mating portion 1122 that are interconnected. The cold plate assembly 100 also includes a locking unit 140, which is located on the same side of the cold plate 110 as the second mounting portion 112, and the locking unit 140 has a locking portion.

[0107] Specifically, when the connector 220 is in the locked position, the locking part engages with the first mating part 1121. The first mating part 1121 is configured to restrict the movement of the locking part toward the cold plate 110, thereby preventing the connector 220 from switching from the locked position to the intermediate position. This further prevents the connector 220 from falling off due to misoperation and ensures the stability of the connection between the cold plate assembly 100 and the disassembly assembly 200.

[0108] When the connector 220 is in the disassembly position, the locking part engages with the second mating part 1122, and when the disassembly part 210 moves toward the side away from the cold plate 110, the locking part can disengage from the second mating part 1122.

[0109] Specifically, in this embodiment, the second mating part 1122 is larger in size than the first mating part 1121 along the moving direction of the connector 220, providing a larger travel range for the locking part. When the disassembly / reassembly assembly 200 needs to be disassembled, the operator first moves the locking part, causing it to slide from the first mating part 1121 into the second mating part 1122. Because the second mating part 1122 has a larger length, the locking part can move within its range, thereby releasing the restriction on the connector 220. This allows the connector 220 to switch from the locked position to the intermediate position, and then from the intermediate position to the disassembly position. Thus, by using mating parts of different sizes, control over the unlocking process is achieved, ensuring the reliability of the locking when the connector 220 is in the locked position.

[0110] Please refer to Figures 1 to 8In some embodiments, the locking unit 140 includes a locking member 141 and an elastic member 142. The elastic member 142 is sleeved on the circumferential outer side of the second mounting portion 112, and the locking member 141 is located at the end of the elastic member 142 facing away from the cold plate 110. The side of the locking member 141 facing the second mounting portion 112 has a locking portion. The first mating portion 1121 is a first groove, and the second mating portion 1122 is a second groove, extending to the end face of the second mounting portion 112 facing away from the cold plate 110. The mounting portion also has a communicating groove 1123, through which the first groove communicates with the second groove. When the connector 220 is in the locked position, at least a portion of the locking portion is located in the first groove. During the process of switching the connector 220 from the intermediate position to the locked position, the locking portion moves into the second groove through the communicating groove 1123.

[0111] Specifically, in this embodiment, both the first and second grooves extend toward the cold plate 110.

[0112] When the connector 220 is in the locked position, the locking part is located in the first groove. Since the length of the first groove is relatively short, it restricts the movement of the locking part, preventing the locking part from moving a sufficient distance toward the cold plate 110 to contact the first guide surface 121 and engage with the guide 120. This prevents the connector 220 from switching from the locked position to the intermediate position, ensuring the locking reliability of the connector 220 in the working state.

[0113] When it is necessary to disassemble the cold plate assembly 100, the operator can first move the locking member 141, causing the locking part to move out of the first groove and into the connecting groove 1123. Then, the locking member 141 is rotated, causing the locking part to move along the connecting groove 1123 into the second groove. Since the second groove has a greater length in the direction towards the cold plate 110, it can provide sufficient movement space for the locking part. At this time, the connecting member 220 can be smoothly switched from the locked position to the intermediate position, completing the unlocking operation.

[0114] When switching the locking state is not required, the locking part can be positioned within the connecting groove 1123. Under the elastic force of the elastic member 142, the locking part can always be abutted within the connecting groove 1123, forming a continuous preload force to prevent the locking part from accidentally disengaging from the connecting groove 1123, avoid the locking function from failing due to vibration or other factors, and further ensure the stability of the locking state.

[0115] In this embodiment, the elastic element 142 is a spring. In other embodiments, the type and structure of the elastic element 142 can be adapted to actual needs. This embodiment does not impose any restrictions on this.

[0116] In this embodiment, the cold plate assembly 100 further includes a second mounting member 150, which passes through the second fixing part 213 to enhance the structural stability of the second fixing part 213.

[0117] Please refer to Figures 1 to 8 In some embodiments, the disassembly / assembly component 210 further includes a second fixing portion 213. When the connector 220 is in the locked position, a portion of the second mounting portion 112 is located within the second fixing portion 213, and the second fixing portion 213 presses against the end of the locking member 141 facing away from the elastic member 142. This allows the locking member 141 to be subjected to the combined action of the second fixing portion 213 and the elastic member 142 in the direction toward the cold plate 110, maintaining a state of force balance. The downward pressure provided by the second fixing portion 213 and the upward elastic force provided by the elastic member 142 cancel each other out, ensuring that the locking member is stably held within the first groove, the second groove, or the connecting groove 1123, and will not be displaced due to equipment vibration or accidental contact.

[0118] Please refer to Figures 1 to 8 In some embodiments, the connector 220 further includes a through-hole portion. The disassembly and assembly assembly 200 also includes a connecting shaft 240 and a reset member 230. The connecting shaft 240 passes through the through-hole portion and is mounted on the disassembly and assembly assembly 210 so that the connector 220 can rotate around the connecting shaft 240. The reset member 230 is sleeved on the circumferential outer side of the connecting shaft 240, with one end of the reset member 230 connected to the disassembly and assembly assembly 210 and the other end of the reset member 230 connected to the connector 220.

[0119] Specifically, in this embodiment, the connector 220 can rotate around the connecting shaft 240 as the rotation center, and the reset member 230 can provide a restoring torque for the connector 220. When the connector 220 is rotated by an external force, the elastic restoring force of the reset member 230 will drive the connector 220 to automatically return to its original position.

[0120] During the switching process from the locked position to the intermediate position, the disassembly component 210 moves toward the cold plate 110, and the mating surface of the connecting end 221 slides along the first guide surface 121. The guiding effect of the inclined surface converts the axial movement into the rotational torque of the connecting component 220 around the connecting shaft 240, causing the connecting end 221 to overcome the elastic force of the reset component 230 and rotate outward, thereby releasing the jamming state with the mating end 131.

[0121] During the transition from the intermediate position to the disassembly position, the connector 220 is guided to rotate by the inclined surface of the second guide surface 122. When the disassembly component 210 moves away from the cold plate 110, the connecting end 221 slides along the second guide surface 122 and rotates to widen the opening angle under the action of the inclined surface until it is completely disengaged from the mating end 131, thereby realizing the disassembly of the disassembly component 200 and the cold plate component 100.

[0122] In this embodiment, the reset member 230 is a torsion spring. In other embodiments, the reset member 230 may be other structures, and this embodiment does not impose any restrictions on this.

[0123] Please refer to Figures 1 to 8 This application also provides an electronic device, including a circuit board 10 and a cold plate disassembly structure as described in any of the above embodiments. The circuit board 10 has electronic components 11, and the cold plate disassembly structure is disposed on the circuit board 10 to dissipate heat from the electronic components 11.

[0124] Specifically, in this embodiment, the circuit board 10 integrates multiple electronic components 11, such as a central processing unit, memory module, graphics processor, and chipset. These electronic components 11 generate a lot of heat during operation and need to be dissipated to maintain normal operating temperature.

[0125] The cold plate assembly and disassembly structure has been described in the above embodiments and will not be repeated here.

[0126] The electronic device provided in this embodiment includes the aforementioned cold plate disassembly and assembly structure, and therefore possesses the beneficial effects of the aforementioned cold plate disassembly and assembly structure. When it is necessary to disassemble or assemble the cold plate assembly 100, the connector 220 can be switched to the locked position, and the operator can hold the disassembly and assembly component 210 with one hand. Since the connector 220 on the disassembly and assembly component 200 is correspondingly connected to each cold plate 110, each cold plate assembly 100 can remain in an assembled state, forming an integral disassembly and assembly structure. The operator's other hand can perform installation, fixing, or disassembly operations between the circuit board 10 and the cold plate 110 without the assistance of other operators, and without the need to disassemble the cooling pipes between the cold plate assemblies 100, greatly simplifying the disassembly operation of the cold plate assembly 100 and improving the efficiency of the disassembly and assembly operation. When it is necessary to disassemble the disassembly and assembly component 200, the connector 220 can be switched to the disassembly position. When the connector 220 is in the disassembly position, the connector 220 rotates toward the side away from the guide 120 so that the connector 220 can be separated from the guide 120 and the mating end 131. This allows the operator to separate the disassembly assembly 200 from the cold plate assembly 100. As a result, when the circuit board 10 is installed inside the electronic device, it does not need to occupy the internal space of the electronic device, which helps to improve the utilization rate of the internal space of the electronic device.
