Description

Technical Field

[0001] This utility model relates to the field of water-cooled plate technology, and in particular to a pull-out water-cooled plate structure. Background Technology

[0002] Data center servers and computing devices generate a significant amount of heat during operation. Insufficient heat dissipation can lead to performance degradation, shortened equipment lifespan, and even malfunctions. With the development of cloud computing and AI technologies, data center power density is constantly increasing, placing even greater demands on cooling efficiency. Water-cooled plates, as key components for direct liquid cooling, can efficiently remove heat.

[0003] However, traditional fixed-location methods require complete disassembly of the equipment for maintenance, leading to extended downtime and impacting service availability and operating costs. In high-availability data centers, rapid maintenance and modular replacement are core requirements. Summary of the Invention

[0004] To address the aforementioned problems, this utility model aims to solve the problems described above. One objective of this utility model is to provide a pull-out water-cooled plate structure that solves the above problems, requires no tools, can be replaced by a single person in minutes, can be replaced individually, is easy to expand, and has no leakage during plugging and unplugging.

[0005] The present invention adopts a pull-out water-cooled plate structure, comprising a mounting rail and a cooling plate body. The cooling plate body is slidably connected to the mounting rail. A cooling channel is provided inside the cooling plate body. A water inlet connector is provided at one end of the cooling channel, and a water return connector is provided at the other end of the cooling channel. The water inlet connector and the water return connector are both located at the same end of the cooling plate body. A positioning member is provided at the end of the cooling plate body. When the cooling plate body slides to a predetermined position, the positioning member locks with the mounting rail.

[0006] One implementation of the positioning component is that the positioning component includes an L-shaped corner bracket and a locking pin. One side of the L-shaped corner bracket is fixedly connected to the cooling plate body. A positioning hole is provided on one side of the L-shaped corner bracket in the horizontal direction. A positioning pin hole is provided on the mounting guide rail. When fixed, the locking pin is simultaneously inserted into the positioning hole and the positioning pin hole.

[0007] To ensure smooth and stable insertion and removal of the cooling plate, the mounting guide rail is provided with a guide groove, and a supporting rib is provided at the bottom of the guide groove. The cooling plate is slidably installed in the guide groove, and the lower side of the cooling plate abuts against the supporting rib. Limiting strips are provided on both sides of the guide groove, and matching limiting grooves are provided on both sides of the lower end of the mounting guide rail. The limiting strips are slidably inserted into the limiting grooves.

[0008] To enable quick installation and replacement while ensuring no leakage, both the inlet and outlet water connectors are quick-connect couplings. A water pipe is also provided to connect to the inlet and outlet water connectors, with a quick-connect clip at the end of the water pipe. During installation, the quick-connect clip engages with the quick-connect coupling.

[0009] For ease of use, a handle is provided at the end of the cooling plate, and the handle is located at the end away from the quick connector.

[0010] To accommodate installation on different devices, the mounting guide rail is provided with mounting holes at the bottom of the guide groove, and the mounting holes are located between the support ribs.

[0011] To prevent water leakage from affecting equipment use, the length of the mounting guide rail is longer than the length of the cooling plate. The water inlet connector and the water return connector are located above the mounting guide rail. The mounting guide rail is inclined, with the end of the mounting guide rail containing the water inlet connector and the water return connector lower than the other end.

[0012] For better heat dissipation, thermal pads are provided on both sides of the cooling plate.

[0013] Preferably, the cooling channels are distributed in the cooling plate body, and the cooling channels are connected from the water inlet connector to the water return connector.

[0014] Compared with the prior art, the pull-out water-cooled plate structure of this utility model has the following technical effects: 1. This application discloses a pull-out water-cooled plate structure, including a mounting rail and a cooling plate body. The cooling plate body is slidably connected to the mounting rail, and forms a standard modular interface with the system body through the rail, becoming an independent replaceable unit. When a water-cooled plate requires maintenance or malfunctions, it can be directly pulled out as a single module without affecting the operation of other water-cooled plates or core equipment in the system, achieving true hot-swappable replacement and reducing maintenance complexity and risk. Maintenance personnel can complete the replacement of a single water-cooled plate module within minutes without any tools, greatly improving maintenance efficiency and significantly shortening downtime caused by heat dissipation system maintenance for data center servers, battery packs, or semiconductor equipment, meeting the stringent requirements of rapid response in high-availability scenarios.

[0015] The cooling plate has a cooling channel inside, with a water inlet connector at one end and a water return connector at the other end. Both the water inlet and return connectors are located on the same side of the cooling plate. By using quick-connect fittings on the integrated water inlet and return connectors, the water passages are automatically connected when inserted and automatically sealed bidirectionally when unplugged, effectively preventing coolant leakage. This connection method is specifically designed for repeated insertion and removal, offering high sealing reliability and a long service life, fundamentally solving the leakage risk caused by repeated disassembly and reassembly of traditional rigid connections.

[0016] A positioning element is provided at the end of the cooling plate. When the cooling plate slides to a predetermined position, the positioning element locks with the mounting rail. The entire fixing mechanism consists of only a few components such as the slide rail and the positioning element, resulting in a simple structure and low manufacturing cost. Its locking and unlocking mechanism is intuitive and reliable, reducing the skill requirements for operators and minimizing potential failure points caused by complex structures, thereby improving the overall system's operational reliability.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0021] The pull-out water-cooled plate structure will be described in detail below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1-4 As shown, a pull-out water-cooled plate structure includes a mounting rail 1 and a cooling plate body 2. The mounting rail 1 serves as the fixed foundation of the structure, rigidly fixed to the equipment rack or wall panel requiring heat dissipation through its own mounting structure, such as the rack of a data center server, the internal frame of a battery pack, or the outer shell of a semiconductor device. The cooling plate body 2 is the core functional component that carries the coolant and directly contacts the device being cooled. Together, they form the basis of a modular design. It decomposes the water-cooling system into fixed parts and movable modules, laying the structural foundation for subsequent rapid maintenance, replacement, and expansion.

[0023] The cooling plate 2 is slidably connected to the mounting rail 1. This sliding connection means that the cooling plate 2 and the mounting rail 1 move relative to each other in a linear fashion via a specific guiding structure. During installation, the operator only needs to push the cooling plate 2 in or pull it out along the axial direction of the rail to complete the installation and disassembly of the entire module, completely avoiding the need for multi-tool, multi-step screw tightening or clamp locking operations required in traditional methods.

[0024] The cooling plate 2 has a cooling channel 21 inside. This cooling channel 21 is a closed flow channel formed by machining inside the metal plate. Coolant flows through this channel under the drive of a pump, and the heat from the cooled device is continuously carried away through heat conduction between the liquid and the metal plate. One end of the cooling channel 21 is provided with a water inlet connector 24, and the other end is provided with a water return connector 25. The water inlet connector 24 is used to connect to the liquid supply pipeline of the external cooling system to introduce low-temperature coolant; the water return connector 25 is used to connect to the liquid return pipeline to discharge the high-temperature coolant after absorbing heat, forming a complete circulation loop. Both the water inlet connector 24 and the water return connector 25 are located at the same end of the same side of the cooling plate 2. This is a key spatial layout design. All external pipeline connections are concentrated at the same end of the cooling plate 2, usually the rear end. When the cooling plate 2 is pushed into place along the guide rail, the connector on this side will simultaneously mate with the corresponding female connector pre-fixed on the equipment frame.

[0025] The cooling plate 2 is equipped with a positioning element at its end. When the cooling plate 2 slides to a predetermined position, the positioning element locks with the mounting guide rail 1. The predetermined position refers to the position where the cooling plate 2 is fully inserted, and all water passage joints are correctly aligned and sealed. The function of the positioning element is to provide a quick and reliable mechanical lock at this position, preventing the cooling plate 2 from loosening or falling out due to vibration or accidental tension during equipment operation.

[0026] One implementation of the positioning component includes an L-shaped bracket 5 and a locking pin 6. One side of the L-shaped bracket 5 is fixedly connected to the cooling plate 2. A positioning hole 51 is provided on the horizontal side of the L-shaped bracket 5, and a positioning pin hole 14 is provided on the mounting guide rail 1. During fixing, the locking pin 6 is simultaneously inserted into the positioning hole 51 and the positioning pin hole 14. The L-shaped bracket 5 is made of stainless steel and is vertically fixed to the rear end of the cooling plate 2 by screws or welding. A positioning pin hole 14 coaxially with the mounting guide rail is also machined at the corresponding position. The locking pin 6 can be a manually operated quick-release pin, a spring pin, or a simple insert pin. After the cooling plate 2 is pushed to the bottom, the operator manually passes the pin through the positioning hole 51 of the bracket and inserts it into the pin hole of the guide rail, thereby forming a rigid stop in the front-rear direction. The combination of the L-shaped bracket 5 and the pin is simple in structure, low in cost, intuitive to operate, and requires no tools.

[0027] To ensure smooth and stable insertion and removal of the cooling plate 2, the mounting rail 1 is provided with a guide groove 11, and a supporting rib 12 is provided at the bottom of the guide groove 11. The cooling plate 2 is slidably installed in the guide groove 11, with its lower side abutting against the supporting rib 12. The guide groove 11 is a U-shaped structure used to accommodate and guide the cooling plate 2. The supporting rib 12 is a strip-shaped structure protruding from the bottom of the guide groove 11, with its top contacting the lower surface of the cooling plate 2. This line contact or small-area surface contact design effectively reduces the friction area during sliding. The supporting rib 12 provides stable support for the cooling plate 2 and minimizes sliding friction, making the pulling operation effortless and smooth. At the same time, it also forms a gap between the cooling plate 2 and the guide rail base, which facilitates air circulation. In case of a small leak, liquid can drain through this gap, preventing accumulation.

[0028] Limiting strips 13 are provided on both sides of the guide groove 11, and matching limiting grooves 22 are provided on both sides of the lower end of the mounting guide rail 1. The limiting strips 13 are slidably inserted into the limiting grooves 22. The limiting strips 13 and the limiting grooves 22 are a pair of precision sliding pairs, which provide a tight fit in the width direction of the cooling plate 2, restricting the movement of the cooling plate 2 in the left-right and up-down directions. Combined with the constraint of the supporting ribs 12 in the up-down direction, and the constraint of the limiting strips 13 and the limiting grooves 22 in the left-right and up-down directions, this guiding structure together achieves precise restriction of the four degrees of freedom of the cooling plate 2. This ensures that the cooling plate 2 follows a straight trajectory during the pulling process, without jamming or skewing, providing a crucial guarantee for the accurate and non-destructive docking of the front quick connector.

[0029] To achieve rapid installation and replacement while ensuring no leakage, both the inlet connector 24 and the return connector 25 are quick-connect couplings. A water pipe 4 is also provided to connect to the inlet connector 24 and the return connector 25. The end of the water pipe 4 is equipped with a quick-connect clip, which engages with the quick-connect coupling during installation. The quick-connect coupling typically contains a spring and a valve core, which automatically seals both ends upon disconnection to prevent liquid leakage, similar to an ISO standard flat quick-connect coupling. The matching quick-connect clip is the locking mechanism on the female end. During connection, simply insert the male connector into the female connector; a click indicates that the quick-connect clip is locked, the valve core is opened, and the water passage is open. For disassembly, simply press or slide the release ring of the quick-connect clip to easily pull it apart. This design solves the problems of traditional threaded / clamp connections, which require tools, have difficult-to-control tightening torque, and are prone to wear and leakage due to repeated disassembly and assembly. Its self-sealing characteristic ensures cleanliness and reliability during insertion and removal, making it an indispensable element for high-maintenance scenarios.

[0030] For ease of use, a handle 23 is provided at one end of the cooling plate 2, located away from the quick connector. The handle 23 can be a recessed finger groove, a protruding pull handle, or an integrated plastic handle, and is located at the front end of the cooling plate 2. Its position is designed to be at opposite ends of the quick connector of the water channel, forming a clear push-pull force point.

[0031] To accommodate installation on different devices, the mounting rail 1 has mounting holes 15 at the bottom of the guide groove 11, located between the support ribs 12. These mounting holes 15 are through holes or threaded holes, used to pass screws to secure the entire mounting rail 1 assembly to the target device. Positioning them between the support ribs 12 avoids load-bearing areas, ensures a flat mounting surface, and provides localized reinforcement to the mounting points using the rib structure.

[0032] To prevent water leakage from affecting equipment operation, the length of the mounting rail 1 is longer than that of the cooling plate 2. The water inlet connector 24 and the water return connector 25 are located above the mounting rail 1. The mounting rail 1 is inclined, with the end of the mounting rail 1 containing the water inlet connector 24 and the water return connector 25 lower than the other end. That is, the rear end of the rail is slightly lower than the front end, forming a small angle. This design ensures that even in the event of a leak in extreme circumstances, the liquid will flow and drip towards the rear end due to gravity along the inclined rail surface, rather than flowing towards the more delicate electronic equipment area at the front. It actively guides potentially leaking liquid away from sensitive electrical components, controlling its impact within a localized area and improving the robustness and safety of the entire system.

[0033] To improve heat dissipation, thermal pads 3 are provided on both sides of the cooling plate 2. The thermal pads 3 are made of soft, high thermal conductivity silicone material and are pre-attached to the surfaces of the cooling plate 2 that contact the heat source. Their softness fills the microscopic air gaps between them. The thermal pads 3 significantly reduce contact thermal resistance, establishing an efficient heat flow path from the heat source to the cooling plate 2, thereby greatly improving the overall heat dissipation efficiency. They also serve as insulation and shock absorbers.

[0034] Preferably, the cooling channels 21 are distributed within the cooling plate 2, and the cooling channels 21 connect from the water inlet connector 24 to the water return connector 25. This flow channel is typically designed as a serpentine, multi-channel parallel, or turbulent structure to allow the coolant to flow fully and evenly through the main heat-absorbing areas of the entire cooling plate 2, avoiding dead zones and maximizing the heat exchange area and time.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that an article or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such an article or apparatus.
