Description
Technical Field
[0001] This utility model relates to the field of computer technology, and in particular to a power supply module and a server. Background Technology
[0002] The ever-increasing computational demands of artificial intelligence are driving a rapid rise in the demand for liquid-cooled data centers. Liquid-cooled data centers typically power servers through power shelves. The power shelf provides power to all nodes within the rack. Given the large number of nodes and high power density, the selection of the power shelf is crucial, with requirements including the performance of its integrated fans for cooling.
[0003] During the server development phase, equipping a large number of power supply racks can delay the development cycle due to production or procurement issues. At the same time, it can also increase costs because the power supply racks are not compatible with the final product. Summary of the Invention
[0004] To address the aforementioned issues, this utility model provides a power supply module that can adjust its power supply configuration according to the power supply requirements of different servers, thereby shortening the R&D cycle and reducing R&D costs.
[0005] The power module provided by this utility model includes: a power distribution board for managing and / or distributing power, wherein multiple input interfaces are provided on one edge of the power distribution board; multiple power supply units electrically connected to the power distribution board through the input interfaces for providing power; and an output connector disposed on one edge of the power distribution board. This solution designs a power module with a simple architecture, low manufacturing and usage costs, multiple power supply units that centrally supply power to the output connector through the power distribution board, high customizability, and flexible and convenient configuration and use, making it suitable for use in the R&D and testing phase of servers.
[0006] As a preferred implementation of the power module, it also includes a housing, which comprises a main body and a base plate. The power supply unit is disposed within a cavity formed by the main body and the base plate. A first partition plate is provided on the upper part of the power supply unit, and the first partition plate is parallel to the base plate. Multiple second partition plates perpendicular to the first partition plate are provided between the first partition plate and the base plate to isolate adjacent power supply units. The interior of the main body is divided into multiple installation spaces by the first and second partition plates, isolating the power supply units from each other. This improves the overall safety of the power module from the side and the robustness of the power supply unit installation. The power supply units can be plugged in and removed from the rear, making installation and removal quick and convenient. At the same time, the division of the installation spaces provides guidance for the installation of the power supply units, ensuring that the power supply units are aligned with the input interface of the power distribution board.
[0007] As a preferred embodiment of the power module, the housing further includes a top plate and a top cover disposed on the upper part of the main body. The top plate and the top cover form a cover that closes on the opening on the upper part of the main body. The front of the top of the power module adopts a window design, which allows for easy inspection and adjustment of the power distribution board. At the same time, the power supply unit can be pushed backward through the window for easy disassembly of the power supply unit.
[0008] As a preferred implementation of the power module, a support plate is vertically disposed between the top plate and the first partition plate. The upper edge of the support plate is fixedly connected to the top plate, and the lower edge of the support plate is fixedly connected to the first partition plate. A space is reserved between the top plate and the first partition plate, which can serve as space for further expansion of the test power module, allowing for the installation of more power modules or other devices. The vertical spatial layout does not increase lateral space and is suitable for the fixed lateral dimensions of the server. The support plate supports the top plate and the first partition plate, ensuring the overall strength and stability of the test power module, especially the top plate, when no expansion devices are installed.
[0009] As a preferred implementation of the power module, the top plate has multiple front insert plates on the side away from the main body; the top cover has multiple rear insert plates on the side away from the main body; the top plate and the top cover are movably connected by the horizontally spaced front and rear insert plates. The side of the top cover is connected to the side of the main body through a convex-groove fit, reducing the overall lateral protrusion of the test power module, while supporting the front area of the top cover upwards, reducing the stress on the front and rear insert plates, preventing bending, and improving the integrity and stability of the test power module.
[0010] As a preferred implementation of a power module, the top cover is folded down near the two sides of the main body to form a folded portion. The folded portion fits into the two side plates of the main body. The folded portion is provided with positioning protrusions. The upper edge of the side plate of the main body is provided with a groove, and the positioning protrusions are engaged in the groove.
[0011] As a preferred implementation of the power module, the groove is L-shaped, including a horizontal section and a vertical section. The horizontal section is located at the lower end of the vertical section and extends towards the rear of the main body. After the protrusion is inserted from the vertical section, it is pushed backward to lock the protrusion into the horizontal section of the groove. This locks in place with the connection holes of the top plate and the rear insert plate, ensuring a secure connection that is not easily lifted.
[0012] As a preferred implementation of the power module, the edge of the top cover away from the top plate is provided with a handle groove. This provides a gripping position, allowing the operator to easily pull out the cover after it is unlocked.
[0013] As a preferred implementation of the power supply module, at least one of the multiple power supply units is a backup power supply unit. The power supply unit adopts an N+1 design, with a backup power supply unit that can take over from the operating power supply unit at any time, thus improving the stability of the power supply.
[0014] On the other hand, this utility model also provides a server, including a server body and the aforementioned power module. A power input interface is provided on the rear window of the server body, and the power input interface is connected to the power output connector of the power module. This server uses the aforementioned power module, which effectively shortens the development cycle, reduces costs during the R&D phase, facilitates the later development and finalization of the power module, and improves the compatibility between the server and the power module.
[0015] As can be seen from the above technical solution, the advantages of this utility model are as follows: This test power module is mainly used in the testing phase of server R&D and design. The design simplifies the complex structure of traditional power modules, adopting a more concise and efficient architecture. This significantly reduces production costs during the R&D, manufacturing, and usage phases, and also reduces maintenance and operation difficulties. The module contains multiple power supply units arranged side-by-side at the rear of the casing. Through centralized management by the power distribution board, power can be effectively output to the server. At least one power supply unit serves as a backup, ensuring the continuity and reliability of power supply. In terms of safety, the module's careful design isolates the power supply units from each other, effectively preventing potential... This reduces the risk of short circuits and improves the overall system safety. Simultaneously, module maintenance is more convenient. Since the power supply unit is removable from the rear, technicians can quickly replace faulty units without disassembling the entire system, significantly shortening repair time and improving server operating efficiency. Furthermore, the module's open design provides technicians with convenient inspection and adjustment space, making power distribution board monitoring and maintenance more intuitive and efficient. The reserved installation space not only allows for future upgrades but also does not require additional lateral space. In terms of stability, the backup power supply unit ensures that it can quickly take over power supply when the main power supply unit fails, greatly improving the stability of the power supply system. Furthermore, applying this power module to the server body not only effectively shortens the server development cycle and reduces R&D costs but also facilitates the development and finalization of subsequent power modules, greatly improving the compatibility between the server and the power module and the overall system performance.

[0022] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0023] Example 1
[0024] This embodiment provides a power module whose basic architecture includes a power distribution board 3, multiple power supply units 2 and an output connector. The power distribution board 3 is used to manage and / or distribute power. Multiple input interfaces 31 are provided on one side edge of the power distribution board 3. The power supply units 2 are electrically connected to the power distribution board 3 through the input interfaces 31 and are used to provide power. The output connector 4 is located on one side edge of the power distribution board 3.
[0025] Specifically, such as Figure 1 , 2 As shown, in this embodiment, the power module includes a housing 1, which is an outer shell structure. The housing 1 is generally a rectangular cube structure, including a main body 11, a bottom plate, a top plate 111, and a top cover 12, which together surround and form the outer structure of the main body 11. Figure 1, Figure 2 The area of the top plate 111 is smaller than that of the bottom plate, and the top plate 111 is located at the rear of the main body 11 (for ease of description, it is defined as follows). Figure 1 , Figure 2 (In the image, the right side is the front and the left side is the rear, the same applies below). Furthermore, the front edge of the top plate 111, the front top edges of the two side panels, and the top edge of the front panel form an open rectangular window. The top cover 12 is detachably mounted on this window, and the outer contour of the top cover 12 is adapted to the shape of the rectangular window, such as... Figure 2 As shown, the top plate 111 has three front insert plates 5 along its front edge, with a certain distance between adjacent front insert plates 5. The horizontal position of the front insert plates 5 is lower than the horizontal position of the top plate 111. The top cover 12 has two rear insert plates 6 along its rear edge. The width of the rear insert plates 6 is not greater than the distance between adjacent front insert plates 5, and the distance between the two rear insert plates 6 is not less than the width of the middle front insert plate 5. The horizontal position of the rear insert plates 6 is lower than the horizontal position of the top cover 12. Specifically, when the top cover 12 is installed on the main body 11, the front insert plates 5 and the rear insert plates 6 are inserted alternately. Then, the top cover 12 is pushed backward, so that the front insert plates 5 are inserted below the top plate 111 and fit against the bottom surface of the top plate 111, and the rear insert plates 6 are inserted into the bottom of the top plate 111 and fit against the top plate 111 (based on the above principle, the number of front insert plates 5 and rear insert plates 6 can also be set to other quantities). Simultaneously, after the rear insert plate 6 is inserted, connecting holes are provided at corresponding positions on the top plate 111 and the rear insert plate 6, or connecting holes are provided at corresponding positions on the front insert plate 5 and the upper cover 12, to connect and lock the top plate 111 and the upper cover. In other embodiments, the connecting holes can also be provided on the rear insert plate and the top plate. In addition, the two side edges of the upper cover 12 are folded down to form folded portions, which fit against the two side plates of the main body 11. The folded portions are provided with positioning protrusions 121. A groove is provided on the upper edge of the side plate of the body 11, and the positioning protrusion 121 is located in the groove. In this embodiment, the groove is L-shaped, including a horizontal section and a vertical section. The horizontal section is located at the lower end of the vertical section and extends to the rear side of the body 11. When the upper cover 12 is installed, the protrusion is inserted from the vertical section and pushed backward to lock the protrusion into the horizontal section of the groove. A handle groove is provided on the front edge of the upper cover 12 so that it can be easily removed after the upper cover 12 is unlocked.
[0026] Inside the housing 1, a first partition plate 13 is provided at the rear of the main body 11. The first partition plate 13 is parallel to the bottom plate of the main body 11. A plurality of second partition plates 14 are provided between the first partition plate 13 and the bottom plate of the main body 11. The second partition plates 14 are perpendicular to the bottom plate of the main body 11. The first partition plate 13, the plurality of second partition plates 14 and the bottom plate of the main body 11 form a plurality of installation spaces. The installation spaces are used to install the power supply unit 2. It can be seen that the plurality of power supply units 2 are arranged side by side and installed at the rear of the housing 1. An insulating layer can be further provided on the second partition plate 14.
[0027] The power distribution board 3 is located at the front of the housing 1 and is fixedly mounted on the bottom plate of the main body 11. The rear edge of the power distribution board 3 is provided with multiple input interfaces 31 corresponding to the multiple power supply units 2. The output interfaces 31 are directly opposite the front end of the aforementioned installation space. As can be seen from the above structure, the rear end face of the main body 11 is an open face. Thus, the power supply units 2 can be directly inserted into the rear of the housing 1, and the front end connector of the power supply unit 2 can be directly inserted into the output interface 31. The front edge of the power distribution board 3 is provided with an output connector 4, the front end of which extends out of the front end face of the housing 1. Among the multiple power supply units 2, at least one is a backup power supply unit. That is, the multiple power supply units of the test power module adopt an N+1 design. When the working power supply fails, the backup power supply can be quickly started to take over its work, ensuring the stability of the current and voltage of the external power supply.
[0028] The top plate 111 is spaced a certain distance from the first partition plate 13, and a support plate 15 is provided. The support plate 15 is perpendicular to the first partition plate 13. The upper edge of the support plate 15 is fixedly connected to the top plate 111, and the lower edge of the support plate 15 is fixedly connected to the first partition plate 13. A space is reserved between the top plate and the first partition plate, which can be used as a space for further expansion of the test power supply module. More power supply modules or other devices can be installed. At the same time, the support plate supports the top plate and the first partition plate, ensuring the overall strength and stability of the test power supply module, especially the top plate, when no expansion devices are installed.
[0029] Example 2

The design simplifies the complex structure of traditional power modules, adopting a more concise and efficient architecture. This significantly reduces production costs during the research and development, manufacturing, and use processes, and also reduces the difficulty of maintenance and operation. The module contains multiple power supply units arranged side-by-side at the rear of the casing.
