Description

Technical Field

[0001] This application relates to the field of server technology, and in particular to a server architecture. Background Technology

[0002] In traditional server designs, especially for rack-mount servers using CRPS power supplies, power supply connections and heat dissipation primarily rely on air cooling systems. While this cooling method can meet certain heat dissipation requirements, it is inefficient and energy-intensive in the high-density deployment environment of data centers. Furthermore, with the continuous increase in power consumption of critical components such as CPUs and GPUs, the limitations of air cooling become increasingly apparent. If the heat inside the server cannot be dissipated effectively and promptly, it will not only significantly increase energy consumption and noise levels but may also lead to performance degradation or even server crashes due to overheating, severely impacting the stable operation of the data center.

[0003] Addressing the insufficient heat dissipation of traditional air-cooled servers, liquid cooling technology, especially immersion liquid cooling, offers a significant solution to the heat dissipation problems of high-power servers. This is because it directly contacts the server's internal heat-generating components and uses a liquid with high specific heat capacity as the heat transfer medium, greatly improving heat dissipation efficiency and reducing the server's Power Usage Effectiveness (PUE). Immersion liquid-cooled servers achieve efficient cooling by immersing high-heat-generating components such as the server motherboard, CPU, and memory in a specially designed tank, utilizing the heat exchange properties of the liquid to remove heat. However, maintaining such liquid-cooled servers presents some significant challenges, especially in confined operating spaces.

[0004] For immersion liquid-cooled servers, internal space is limited, especially during the conversion of the server motherboard to immersion liquid cooling, requiring the design of an additional embedded PDB board (power board) to interface with CRPS power supplies. However, due to the limited internal space of the tank, the size of the PDB board is usually restricted to a small range, while the insertion and extraction force of the CRPS power connector is relatively large. This poses a significant challenge to maintenance personnel when directly operating the PDB board in a confined space. Directly operating the PDB board for insertion, removal, or maintenance is not only inconvenient but may also increase the difficulty of operation due to space constraints, leading to low maintenance efficiency and even potential damage to internal server components due to improper operation.

[0005] Furthermore, in existing immersion liquid-cooled servers, maintenance or PDB board replacement often requires operation from the side of the server. This is particularly problematic in practical deployments due to the limited front-to-back layout and maintenance space of rack-mounted servers, making the process exceptionally complex. In environments with multiple servers deployed side-by-side, the space for side-operation is further reduced, increasing the difficulty of maintenance.

[0006] Therefore, existing technologies have significant shortcomings in maintaining the PDB board of immersion liquid-cooled servers. There is a need to develop a structural design that enables easy plug-and-play maintenance in confined spaces to improve the maintainability and ease of operation of the server.

At least a portion of the first positioning protrusion is inserted into the limiting space to limit the range of movement of the tray in the horizontal direction.

[0011] Furthermore, the second positioning part is a second positioning protrusion, and the fourth positioning part is a slot. At least a portion of the second positioning protrusion abuts against the side wall of the slot so that during the rotation of the handle, the second positioning protrusion pushes the handle to move the tray along a predetermined direction.

[0015] Furthermore, the fifth positioning part is a spring piece, at least a portion of which protrudes relative to the side of the tray; the sixth positioning part is a positioning hole. During the rotation of the handle, the spring piece is pressed to compress it, and then the spring piece is inserted into the positioning hole under the action of elastic restoring force, so that the handle is rotated to a predetermined position.

[0016] Furthermore, a seventh positioning part is provided on the tray, which protrudes relative to the side of the tray, and a limiting end face is provided on the handle, at least a portion of which abuts against the seventh positioning part so that the handle can be rotated to a predetermined position.

[0018] Furthermore, the eighth positioning part is a third positioning protrusion, and the ninth positioning part is a flange. The flange is folded from the pallet toward the side of the pallet, and at least a portion of the flange is in contact with the third positioning protrusion to limit the pallet in the second direction.

[0036] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] As mentioned in the background section, traditional rack-mount servers have a front and rear rack. The rear typically houses the CRPS power supply, fans, PCIe cards, and other modules. Connections between these modules and the rack's PDU / SWITCH are also made at the rear. In contrast, typical immersion liquid-cooled servers, due to the structural limitations of the tank, can only be maintained from one side—the top and bottom. The bottom usually houses the power supply busbar for the entire tank and the liquid circulation system. Therefore, it typically draws power directly from a centralized POWER CLIP and connects to the motherboard's Power Connector. Applying rack-mount CRPS power supplies directly to immersion liquid cooling requires an additional embedded PDB (Power Board) due to the lack of suitable cabling. However, tank space constraints necessitate designing the PDB based on the motherboard's dimensions, resulting in a relatively short size. The insertion and extraction forces of the CRPS connectors are relatively high, making maintenance of the PDB very difficult within the limited space. Therefore, the server structure provided in this application, through the rotatable design between the handle and the tray, and the interaction between the fourth positioning part on the handle and the second positioning part on the base, generates a lever effect when the handle is rotated, which transforms the insertion and extraction force into a more controllable rotation operation, significantly reducing the physical burden on maintenance personnel during operation. By adopting a vertical operation method instead of a horizontal operation method, it overcomes the problems of limited space and inconvenient power board installation and maintenance in traditional server structures.

[0038] Specifically, such as Figures 1 to 7As shown, an embodiment of this application provides a server structure, including: a base 10, on which a first positioning part 11 and a second positioning part 12 are disposed; a power board assembly 20, disposed on the base 10, the power board assembly 20 including a tray 21 and a handle 22, the handle 22 being disposed on the tray 21 and rotatably disposed relative to the tray 21; wherein, a third positioning part 211 is disposed on the tray 21, at least a portion of the third positioning part 211 being inserted into the first positioning part 11 to position the tray 21 onto the base 10; a fourth positioning part 221 is disposed on the handle 22, the fourth positioning part 221 abutting against the second positioning part 12, so that during the rotation of the handle 22, the interaction force between the second positioning part 12 and the fourth positioning part 221 pushes the tray 21 to move in a predetermined direction. This configuration allows the tray 21 to be vertically placed onto the base 10 during the installation of the power board assembly 20. The tray 21 is positioned by the cooperation between the first positioning part 11 and the third positioning part 211. At the same time, the second positioning part 12 and the fourth positioning part 221 remain in contact. During the rotation of the handle 22, the second positioning part 12 provides a pushing force to the handle 22, which in turn moves the tray 21 horizontally, thus achieving the installation of the tray 21. This facilitates a simple and effective connection between the tray 21 and the base 10, increasing the usability of space.

[0039] In specific implementation, such as Figure 4 As shown, the third positioning part 211 includes a limiting space 212. At least a portion of the first positioning part 11 is provided with a first positioning part 11 and a second positioning part 12 on the insertion base 10. Located within the limiting space 212, the limiting space 212, in cooperation with the first positioning part 11, limits the movement of the tray 21. The cooperation between the limiting space 212 and the first positioning part 11 allows for precise control of the movement path and position of the tray 21, ensuring accurate alignment of the power board assembly during installation and disassembly. When performing maintenance in confined spaces, the limiting space 212 ensures that the operator can accurately position and fix the power board assembly even within a limited field of view and operating range, reducing the dependence of maintenance work on the operating environment and skill requirements.

[0040] The limiting space 212 is strip-shaped, and the first positioning part 11 is a first positioning protrusion that cooperates with the limiting space 212. At least a portion of the first positioning protrusion is inserted into the limiting space 212 to limit the horizontal movement range of the tray 21. In this application, the first positioning part 11 includes an H-beam, which is inserted into the limiting space 212 to position the tray 21. The combination of the strip-shaped limiting space and the first positioning protrusion can provide precise guidance and limitation for the tray 21, ensuring that the horizontal movement trajectory of the tray 21 is accurate, avoiding installation errors of the power board components caused by inaccurate positioning, and improving the stability and reliability of the server's internal structure.

[0041] In a specific implementation, the second positioning part 12 is a second positioning protrusion, and the fourth positioning part 221 is a slot 222. At least part of the second positioning protrusion abuts against the side wall of the slot 222 so that when the handle 22 is rotated, the second positioning protrusion pushes the handle 22 to drive the tray 21 to move in a predetermined direction.

[0042] And / or,

[0043] The fourth positioning part 221 has at least one inclined surface that contacts the second positioning part 12 so as to push the tray 21 to move in a predetermined direction during the rotation of the handle 22.

[0044] In the first embodiment provided in this application, the fourth positioning part 221 is a slot 222, and the side wall of the slot 222 abuts against the second positioning protrusion. During the rotation of the handle 22, the interaction force between the side wall and the second positioning protrusion is used to push the tray 21 to move in the horizontal direction. In this way, the abutment between the side wall of the slot 222 and the second positioning protrusion, in conjunction with the first positioning part 11 and the third positioning part 211, can restrict multiple degrees of freedom of the tray 21. Optionally, the second positioning protrusion is a shaft.

[0045] In the second embodiment provided in this application, the fourth positioning part 221 has at least one inclined surface, which contacts the second positioning part 12. Optionally, the second positioning part 12 is a second positioning protrusion, preferably a shaft. In this way, during the rotation of the handle 22, the rotational movement of the handle 22 can act on the protrusion through the inclined surface, converting the rotational force into a translational force. This design can effectively reduce the force required by the operator when pushing the tray 21. At the same time, the end of the inclined surface can serve as a limiting point to prevent the tray 21 from moving excessively and ensure the stable connection of the power board assembly.

[0046] By rotating the handle, and utilizing the abutment of the second positioning protrusion against the side wall of the slot 222 or the guidance of the inclined surface, the tray can be easily moved along a preset direction. This greatly reduces the maintenance difficulty of the PDB board (Power Distribution Board) in confined spaces, allowing operators to complete the installation and removal of the power board more conveniently and efficiently. Compared to the traditional method of directly plugging and unplugging the power board, this design transforms the rotation of the handle into pushing the horizontal movement of the tray, significantly reducing the insertion and extraction force required, lowering the physical burden during operation, and also reducing the risk of damage to the power board or connectors due to excessive insertion and extraction force. The precise fit between the second positioning protrusion and the slot or inclined surface not only ensures the stability and accuracy of the tray during movement but also provides a positioning function for the handle in non-operational states, preventing accidental movement of the handle and enhancing the stability of the entire power board structure.

[0047] In the third embodiment provided in this application, the side wall of the slot 222 is an inclined surface, and the second positioning protrusion is a shaft. During the rotation of the handle 22, the inclined surface and the shaft abut against each other, converting the rotational motion of the handle 22 into the force that moves the tray 21 in the horizontal direction.

[0048] like Figure 5 As shown, the tray 21 is provided with a fifth positioning part 214 that can be elastically deformed, and the handle 22 is provided with a sixth positioning part 223. At least a portion of the sixth positioning part 223 is inserted into the fifth positioning part 214 to rotate the handle 22 to a predetermined position. The insertion design of the fifth positioning part 214 and the sixth positioning part 223 ensures that the handle 22 is securely locked in the predetermined position, preventing accidental rotation of the handle 22 when not in operation, and improving the operational stability of the power board assembly 20 during installation and disassembly. By simply rotating the handle 22, the power board assembly 20 can be quickly connected or disconnected from the base 10 without the need for complex tools or additional fixing structures, significantly simplifying the maintenance process and improving maintenance efficiency.

[0049] Optionally, the fifth positioning part 214 is a spring clip, at least a portion of which protrudes relative to the side of the tray 21; the sixth positioning part 223 is a positioning hole. During the rotation of the handle 22, the spring clip is pressed, causing it to compress. Under the action of elastic restoring force, the spring clip inserts into the positioning hole, thereby rotating the handle 22 to a predetermined position. The fifth positioning part adopts a spring clip design, which can automatically insert into the positioning hole by the elastic restoring force of the spring clip when the handle is rotated to the predetermined position, forming a stable locking effect. This ensures that the position of the handle is stable in the non-operating state and avoids the handle position from changing due to accidental contact, thereby affecting the connection stability of the power board assembly.

[0050] In confined spaces, the combination of spring clips and positioning holes allows maintenance personnel to position the handle simply by applying appropriate rotational force, without having to apply significant force directly to the power board assembly. This reduces maintenance difficulty and is particularly suitable for situations where maintenance space is limited inside the server.

[0051] In the specific implementation process, such as Figure 5 As shown, a seventh positioning part 215 is provided on the tray 21, protruding from the side of the tray 21. A limiting end face 224 is provided on the handle 22, at least a portion of which abuts against the seventh positioning part 215 to rotate the handle 22 to a predetermined position. The abutment between the seventh positioning part 215 and the limiting end face 224 ensures precise control of the rotation angle of the handle 22 during operation, preventing over-rotation and thus avoiding misalignment of the power board assembly installation position or damage to the connector due to excessive operation caused by improper rotation angle, thereby improving the accuracy and safety of operation. When performing maintenance in confined spaces, the design of the limiting end face 224 and the seventh positioning part 215 allows the operator to easily identify the correct rotation angle of the handle 22, reducing the difficulty of performing complex operations when visibility is obstructed or operating space is limited.

[0052] The seventh positioning part 215 is a strip-shaped protrusion. During the rotation of the handle 22, the positioning hole first engages with the spring piece, and the spring piece is inserted into the positioning hole. At this time, the limiting end face 224 on the handle 22 is in contact with the top surface of the strip-shaped protrusion to prevent the handle from rotating excessively. This avoids the offset of the power board assembly installation position due to improper rotation angle, or damage to the connector due to excessive operation, thus improving the accuracy and safety of operation.

[0053] Furthermore, the base 10 is provided with an eighth positioning part 13, and the tray 21 is provided with a ninth positioning part 213. At least a portion of the eighth positioning part 13 is in contact with the ninth positioning part 213 to limit the position of the tray 21. The contact between the eighth and ninth positioning parts further improves the positioning accuracy of the power board assembly on the base, ensuring the precise installation of the power board inside the server. When the tray 21 is placed vertically, the first positioning part 11 on the base 10 is first inserted into the third positioning part 211, and at the same time, the eighth positioning part 13 and the ninth positioning part 213 are in contact. The two cooperate with each other to position the tray 21, so as to ensure that the tray 21 moves along a predetermined horizontal direction.

[0054] In the embodiments provided in this application, the eighth positioning part 13 is the third positioning protrusion, and the ninth positioning part 213 is a flange. The flange is folded from the tray 21 toward the side of the tray 21, and at least a portion of the flange is in contact with the third positioning protrusion to limit the tray 21 in the second direction. Through the precise cooperation between the ninth positioning part 213 (flap) and the eighth positioning part 13 (third positioning protrusion), the positioning of the power board assembly on the base is more accurate, and even in a confined space, quick and accurate alignment and installation can be achieved.

[0055] like Figures 3 to 7 As shown, the handle 22 includes a first rotating frame 225, a second rotating frame 226, and a connecting frame 227. The first rotating frame 225 and the second rotating frame 226 are rotatably connected to two opposite sides of the tray 21, respectively. The two ends of the connecting frame 227 are connected to the first rotating frame 225 and the second rotating frame 226, respectively. The first rotating frame 225 and the second rotating frame 226 are respectively provided with a fourth positioning part 221.

[0056] The handle 22 is rotatably connected to the tray 21 via the first rotating frame 225 and the second rotating frame 226. The fourth positioning part 221 on the first rotating frame 225 and the second rotating frame 226 can evenly distribute the force to both sides when the handle 22 is rotated, thus avoiding the tray 21 from shifting or being damaged due to unilateral force.

[0057] The connecting frame 227 is equipped with an operating part, which is a recessed structure on the connecting frame 227. The operator can operate the connecting frame 227 through the recessed structure to push the handle 22 to rotate.

[0058] Two support frames 14 are provided on the base 10, and the two support frames 14 are respectively located on both sides of the tray 21. The two support frames 14 are respectively provided with second positioning parts 12. The two support frames 14 are respectively located on both sides of the tray 21, providing stable support points for the rotation of the handle 22, ensuring the stability during operation, and avoiding the displacement or damage of the power board assembly due to unstable rotation of the handle.

[0059] In practical implementation, the server structure also includes a motherboard 30 and a liquid-filled block 40. The motherboard 30 is mounted on the base 10 and mainly refers to existing motherboards that support CRPS power supplies. Two CRPS power connectors are located at the rear of the motherboard. The insertion and extraction force of a single CRPS power connector is 15KGF; with two connectors, it reaches 30KGF, which is difficult to operate within a 45mm operating space. The liquid-filled block 40 is mainly used in immersion liquid-cooled servers. Because immersion liquid cooling fluid is very expensive, the space in immersion servers is generally made of materials that do not react with the immersion coolant, forming various solid blocks that occupy unused space. This allows for relatively less coolant to be used, thus reducing costs.

[0060] A PDB board, or power supply board, is a power adapter board developed to directly utilize the existing motherboard. It can connect to the power supply in the server rack or tank and convert it into the power required by the motherboard.

[0061] Base 10: A major component of the server chassis, ensuring the overall strength of the server and mainly used to secure modules such as the motherboard, power supply, and hard drives.

[0062] During assembly, the power board 23 is first fixed to the power board tray 21 with screws. The bottom of the tray 21 has a limiting space 212 that aligns with the I-beams on the base 10. The handles 22 of the tray 21 are riveted to both sides. The handles 22 can rotate through the riveted position and have slots to contact the shafts on the support frame 14. Spring tabs are designed at the front ends of both sides of the tray 21 to engage with the positioning holes on the handles 22, preventing them from easily disengaging without releasing the locking mechanism. In use, the entire power board module is vertically downwards with the handles open. The entire module, relying on the flanged structure at the rear of the power board tray, aligns with the riveted stop protrusions (eighth positioning part 13) on the chassis and is lowered vertically. Upon contact with the chassis, the I-beams on the chassis base align with the limiting space of the PDB board tray, and the slots on both sides of the handles align with the shafts on the support frame. Rotate the handle downwards, and under the interaction of forces, the entire PDB module slides forward. During the sliding process, the I-beam pins on the base restrict the four degrees of freedom: up, down, left, and right. As the handle is pressed down to the bottom, the entire PDB module moves to the front end. At this time, the handle 22 of the PDB board is installed to the bottom, and the handle is engaged with the spring clip of the tray. The handle slot and the rotating shaft on the support frame are engaged with each other, which also serves to prevent the module from turning back.

[0063] In this application, it should be explained that a liquid-cooled server refers to a server in which liquid is injected into the server, and heat dissipation is carried away through heat exchange. From a physical perspective, liquid-cooled servers can be categorized as: cold-plate type liquid-cooled servers and fully immersion type liquid-cooled servers. The liquid-cooled server in this utility model refers to a fully immersion type liquid-cooled server.

[0064] Immersion liquid-cooled servers refer to servers where the entire chassis, including the motherboard, CPU, memory, and other heat-generating components, is completely submerged in refrigerant. During operation, these heat-generating components produce heat, causing the refrigerant temperature to rise. The refrigerant is stored in a tank, and a cooling circulation system within the tank ensures a PUE (Power Usage Effectiveness) of less than 1.1, meeting national energy efficiency requirements. Immersion cooling technology utilizes the liquid to directly remove heat, reducing thermal resistance during heat transfer. Compared to plate-type liquid cooling, immersion liquid cooling technology has higher heat transfer efficiency and is the most energy-efficient and high-performance emerging cooling mode among liquid cooling technologies. Liquid cooling does not simply refer to water; it refers to using a liquid with a high specific heat capacity as a transport medium to remove heat from servers and other IT equipment, thus cooling them. In single-phase immersion liquid cooling, the electronic fluorinated liquid remains in the liquid phase. The electronic components are directly immersed in a fluorinated liquid with dielectric properties, while the liquid is placed in a sealed but easily accessible cabinet. Heat is transferred from the electronic components to the liquid, and a circulating pump typically circulates the heated electronic fluorinated liquid to a heat exchanger. The liquid is then cooled in the heat exchanger and returned to the cabinet.

[0065] TANK, TANK is an immersion enclosure used to install servers / switches. The cooling medium inside the tank directly dissipates heat from the switch. Here, "tank" refers to the immersion enclosure.

[0066] PUE, short for Power Usage Effectiveness, is an indicator for evaluating the energy efficiency of data centers. It is the ratio of all energy consumed by the data center to the energy consumed by the IT load. PUE = Total Data Center Energy Consumption / IT Equipment Energy Consumption. Total data center energy consumption includes the energy consumption of IT equipment and systems such as cooling and power distribution. A value greater than 1 and closer to 1 indicates less energy consumption by non-IT equipment, meaning better energy efficiency. PUE (Power Usage Effectiveness) has become an internationally accepted measure of data center power efficiency. The closer a PUE value is to 1, the higher the greenness of a data center. Currently, advanced data centers abroad typically have PUE values ​​less than 2, while most data centers in my country have PUE values ​​between 2 and 3. Therefore, 1W of power consumption from chip-level main equipment in a domestic data center can lead to a total power consumption of 2-3W, while in a foreign data center, 1W of power consumption from chip-level main equipment would only lead to a total power consumption of less than 2W.
