Description

Technical Field

[0001] This application relates to a server liquid-cooled test platform with a rotation function, belonging to the field of liquid-cooled electronic test equipment. It is mainly used to test the interference or abnormal electromagnetic interference that may occur when a liquid-cooled server is in the same environment but in different orientations. By means of a drive motor and gear transmission mechanism, the turntable can be driven to rotate in the base, so that the server can rotate to different angles. The liquid pipe in the central shaft of the turntable is equipped with a bearing joint, so that when the server rotates, the liquid pipe can still remain in the same position and is not restricted by the rotation of the turntable. Background Technology

[0002] With the increasing demands of AI, cloud computing, and high-performance computing, server processors are generating increasingly higher power consumption. Traditional fan cooling technology is no longer sufficient to effectively dissipate heat, potentially affecting system stability and component lifespan. Liquid cooling systems, due to their highly efficient heat transfer characteristics, are gradually becoming the new mainstream cooling solution for high-performance servers. Liquid cooling technology can directly contact the heat source, effectively reducing the temperature of core components such as the CPU and GPU. Especially in high-temperature, enclosed, or extreme environments, liquid cooling systems can maintain stable server operation. Facing the demands of high-power computing and the trend towards energy conservation and carbon reduction, liquid cooling technology not only improves server cooling efficiency but also helps reduce PUE (Power Usage Effectiveness), meeting environmental and regulatory requirements. Therefore, liquid-cooled servers will be the core architecture primarily used in future green data centers.

[0003] Due to the demand for efficient AI computing, multiple servers must be connected via a high-speed network and clustered to meet complex computational requirements. However, to avoid electromagnetic interference between servers when multiple servers are stacked, each server must undergo rigorous electromagnetic compatibility (EMC) testing upon installation.

[0004] Furthermore, liquid-cooled servers have complex structures and are heavy, making it difficult for traditional fixed test racks to accurately obtain test data from different angles. In addition, liquid-cooled server testing requires ensuring continuous cooling circulation of the liquid, which traditional fixed test racks cannot meet the requirement of rotating the server while maintaining continuous circulation of the liquid pipes without tangling.

[0005] Therefore, this application proposes a test platform with a rotation function, in which the server is placed on a turntable. The turntable carrying the server is driven to rotate by a drive motor and gear mechanism at the bottom of the base, so that the server can change its orientation at a specific angle in a fixed field. This facilitates the testing of electromagnetic radiation data from all directions, and allows for further corrections and adjustments, thus solving the problem of magnetic interference from the server. Utility Model Content

[0006] This application aims to provide a server liquid cooling test platform with rotation function. The platform includes a rotatable turntable and a server support structure, and is designed with a drive mechanism and a rotary liquid cooling interface, so that the server can automatically rotate and change angles when performing EMI and thermal energy tests, and the liquid cooling system will not be interrupted due to rotation, thereby improving test efficiency and safety.

[0007] The test platform of this application includes a rectangular base with a circular turntable mounted on it. The turntable is capable of rotating via a central motor, and radial supports are installed below it to improve the turntable's strength and load-bearing capacity. The turntable contains coolant pipes and rotary joints. One end of the pipes is connected to a liquid cooling system, and the other end is connected to a server water cooling module. The coolant flow is maintained uninterrupted during rotation thanks to a bearing structure.

[0008] The feature of this application is that it combines mechanical rotation mechanism and fluid rotation interface technology, so that the turntable can rotate without interference, so that the server can be tested in different directions without interrupting the cooling system, thereby improving the problems of limited angle and discontinuous cooling of traditional server liquid cooling test platforms.

[0015] Please refer to the following at the same time. Figure 1 and Figure 2 This is a side and top view schematic diagram of the server liquid cooling test platform with rotation function of this application. The test platform consists of a rectangular base 2 with a circular turntable 21. The turntable 21 is used to support server equipment, specifically for placing the server 3 to be tested on it. To ensure overall robustness, the turntable 21 has radially arranged supports 22 and a power distribution panel 5 below it. A drive mechanism is provided between the turntable 21 and the base 2. The drive mechanism includes a drive motor 4 and a gear set. The gear set includes a gear 41, an outer ring gear 42, and an inner ring gear 43. The gear 41 drives the outer ring gear 42 and the inner ring gear 43 to rotate the turntable 21, causing the server 3 above to change different angles and orientations.

[0016] To meet the heat dissipation requirements of the server 3 during rotation, the central shaft 44 of the turntable 21 is equipped with liquid pipes 11 and 12, one of which is a coolant inlet pipe and the other is a coolant return pipe, which are respectively connected to the external liquid cooling system 1 and the cooling module inside the server 3. Through this closed-loop system, the coolant can continuously flow to remove the heat generated by the server 3, forming a cooling liquid circulation.

[0017] To prevent the pipes from twisting or coming off during rotation, a bearing connector 13 is provided below the liquid pipes 11 and 12. This connector 13 contains a bearing assembly 131. Figure 4 As revealed, it allows relative rotation between the two pipe sections. When the server 3 rotates on the turntable 21, the rotating structure of the bearing joint 13 ensures that the liquid pipes 11 and 12 remain aligned. The bearing joint 13 provides the relative rotational freedom for the two connected liquid pipe sections without being restricted by the rotation of the turntable 21, thus maintaining uninterrupted liquid flow. This design effectively improves the stability and durability of the liquid cooling cycle.

[0018] When server 3 is installed on turntable 21 and drive motor 4 is started, turntable 21 can perform precise positioning or continuous rotation, allowing server 3 to be tested at any angle. This design is particularly suitable for occasions that require all-round electromagnetic radiation monitoring, RF shielding effectiveness testing, or signal interference simulation of server 3 casing. It tests electromagnetic radiation data from all directions, makes adjustments, and solves the problem of server magnetic interference. Only then can multiple servers be assembled and installed to form cluster computing to meet complex computing needs.

[0019] Please see again Figure 4To ensure that the liquid pipes 11 and 12 remain aligned and unaffected by the rotation of the turntable 21 when the server 3 rotates on the turntable 21, the main technology involves installing a bearing connector 13 below the liquid pipes 11 and 12 at the central axis 44 of the turntable 21. This bearing connector 13 connects the two pipe sections, and a bearing assembly 131 is installed inside the bearing connector 13 at one end. When the turntable 21 rotates, the bearing assembly 131 ensures that the cooling liquid in the liquid pipes 11 and 12 continues to circulate without tangling, and is not restricted by the rotation of the turntable 21.

[0020] In summary, this application provides an innovative server liquid-cooled test platform design that combines rotational testing and liquid cooling capabilities, significantly improving the flexibility and stability of testing operations. In particular, the bearing joint and cooling circulation design provide reliable technical components for server liquid-cooled testing equipment, aligning with the industry's future development trends of automation, high-density heat dissipation, and multi-faceted testing.
