[0002] As AI becomes increasingly important, the combination of NPU / GPU will become the backbone of future computing systems. When GPUs are placed in poorly cooled conditions, it can lead to premature GPU driver failure and numerous malfunctions in other server components, potentially causing system crashes and freezes. Therefore, during the server development phase, rigorous GPU thermal testing is crucial. However, GPU thermal testing is a complex and time-consuming process, often resulting in wasted time and manpower without obtaining accurate test data. Furthermore, unavoidable personnel movement during testing can cause changes in airflow and ambient temperature, leading to inaccurate test results and ultimately causing deviations in the GPU's thermal design.

[0058] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0059] like Figures 1 to 11 As shown, this embodiment proposes a water-cooling device for simultaneous aging tests of multiple GPUs, including:

[0060] The aging rack 1 has multiple accommodating cavities for testing;

[0061] The detection module 2 is arranged in a one-to-one manner within the receiving cavity. The detection module 2 includes a detection platform 21, which slides horizontally and is used to support and detect the GPU.

[0062] The liquid cooling module 3 includes a liquid-cooled pressure head 31 located in the receiving cavity. The liquid-cooled pressure head 31 is located above the detection platform 21 and can move in the horizontal and vertical directions respectively. The liquid-cooled pressure head 31 has a cooling channel inside. After the liquid-cooled pressure head 31 moves, it contacts the GPU being detected. There are multiple liquid-cooled pressure heads 31, which are set up one-to-one with the detection platform 21. The liquid cooling module 3 also includes a water-passing module, which is connected to the cooling channel and is set up one-to-one with the liquid-cooled pressure head 31.

[0063] Drive module 4 is set in the receiving cavity and is used to provide power to the liquid-cooled pressure head 31. There are multiple drive modules 4 and they are set one-to-one with the liquid-cooled pressure head 31.

[0064] The control module 5 is located on the top of the aging rack 1 and is electrically connected to the detection module 2 and the liquid cooling module 3. The control module 5 includes a display screen 51 and a control panel 52. There are multiple displays screens 51 and control panels 52, and they are arranged one-to-one outside the receiving cavity. The control module 5 also includes a liquid temperature detection unit, a liquid flow adjustment unit, a pressure detection unit and a leakage monitoring unit.

[0065] In this embodiment, the water-cooling equipment for simultaneous aging tests of multiple GPUs includes an aging rack 1, a detection module 2, a liquid cooling module 3, a drive module 4, and a control module 5. The aging rack 1 has multiple cavities arranged vertically in a stacked configuration, each housing a GPU for aging and performance testing. The detection module 2 is located within each cavity and is used for GPU aging and performance testing. Each cavity has a corresponding detection module 2, improving detection accuracy. The detection module 2 includes a detection platform 21 for placing the GPU. The platform 21 can slide horizontally, facilitating GPU placement and reducing operator workload. The liquid cooling module 3 includes a liquid cooling head 31 located within the cavity and contacting and cooling the GPU during testing. The liquid cooling head 31 can move both vertically and horizontally. This allows for monitoring of GPUs of different specifications. The liquid-cooled pressure head 31 has a cooling channel inside. When the liquid-cooled pressure head 31 moves, it contacts the GPU. The number of liquid-cooled pressure heads 31 and the detection platform 21 are the same and they are configured in a one-to-one correspondence. The liquid-cooling module 3 also includes a water-passing module, which connects to the cooling channel and provides coolant to it. The drive module 4 is located inside the housing and provides the power for the movement of the liquid-cooled pressure head 31. There are multiple drive modules 4, each corresponding to a liquid-cooled pressure head 31. The control module 5 is electrically connected to the detection module 2, the liquid-cooling module 3, and the drive module 4. The control module 5 stores the entire device's operating program, such as the detection program and the movement program. Furthermore, the control module 5 also includes a liquid temperature detection unit, a liquid flow adjustment unit, a pressure detection unit, and a leakage detection unit.

[0066] The water-cooling device for simultaneous aging testing of multiple GPUs provided by this invention can complete the aging test of GPUs and provide efficient cooling during the test process, thereby ensuring that the GPU can always work at full load, reducing the entire cycle of the aging test and greatly reducing the time of the GPU aging test. In addition, since it has multiple detection modules 2 and each detection module 2 does not interfere with each other, it can simultaneously perform aging and performance testing on GPUs of different specifications, improving detection efficiency, reducing the labor intensity of operators, and facilitating the overall processing and analysis of data.

[0067] Furthermore, such as Figures 1 to 11 As shown, this embodiment proposes that the detection module 2 also includes auxiliary components. Multiple auxiliary components are configured one-to-one with the detection platform 21. The auxiliary components include:

[0068] Auxiliary frame 22 is disposed inside the receiving cavity and located on both sides of the detection platform 21;

[0069] Auxiliary roller 23 is rotatably mounted on auxiliary frame 22. The outer edge of auxiliary roller 23 makes rolling contact with detection platform 21. Multiple auxiliary rollers 23 are arranged side by side on one auxiliary frame 22.

[0070] Handle 24 is set on the detection platform 21 and is used to provide the operator with a pulling space.

[0071] In this embodiment, to facilitate the placement of the GPU onto the testing platform 21 on each layer, the testing module 2 also includes auxiliary components. These auxiliary components help operators easily add the GPU to the testing platform 21, thereby preventing the GPU from being scratched or damaged during placement. Multiple auxiliary components are included, with the number of auxiliary components matching the number of testing platforms 21, and all are arranged in a one-to-one correspondence. The auxiliary components include auxiliary frames 22, auxiliary rollers 23, and handles 24. The auxiliary frames 22 are disposed within the receiving cavity and located on both sides of the testing platform 21, connected to the aging rack 1. The auxiliary rollers 23 are rotatably connected to the auxiliary frames 22, with each auxiliary frame 22 corresponding to multiple auxiliary rollers 23. The outer edge of the auxiliary rollers 23 makes rolling contact with the testing platform 21. By setting the auxiliary rollers 23, the friction between the testing platform 21 and the auxiliary frames 22 can be reduced, thereby reducing the friction between the testing platform 21 and the aging rack 1. The handles 24 are disposed on the testing platform 21. When the operator needs to place the GPU on the detection platform 21, they only need to pull out the detection platform 21 by using the handle 24. Then the detection platform 21 is mostly located outside the receiving cavity, which makes it easy to put the GPU into the detection platform 21.

[0072] Furthermore, such as Figures 1 to 11 As shown, this embodiment proposes that the detection module 2 also includes a limiting component. A limiting groove is opened on the side of the detection platform 21. The limiting component includes a limiting housing and a limiting pin 25. The limiting housing is fixed on the bottom wall of the receiving cavity and located on the side of the detection platform 21. The limiting pin 25 passes through the limiting housing and its end faces the side of the detection platform 21 where the limiting groove is located.

[0073] In this embodiment, to prevent the testing platform 21 from falling out of the aging rack 1 due to operator error, the testing module 2 also includes a limiting component. This limiting component limits the maximum distance the testing platform 21 can be pulled out. The limiting component includes a limiting housing and a limiting pin 25. A limiting groove is formed on the side of the testing platform 21, and the limiting pin 25 can be inserted into the limiting groove to prevent the testing platform 21 from moving further out of the aging rack 1. First, the limiting pin 25 is pushed out, and then the operator pulls the testing platform 21 using the handle 24. At this time, the limiting pin 25 slides within the limiting groove until it contacts the end of the limiting groove, thus preventing the testing platform 21 from moving further out of the aging rack 1.

[0074] Furthermore, such as Figures 1 to 11 As shown, this embodiment proposes that the detection module 2 also includes an air-cooling component 27, which is electrically connected to the control module 5 and is disposed on the detection platform 21. The air-cooling component 27 includes a fan, and the air outlet of the fan faces the GPU being detected.

[0075] In this embodiment, although the device provided by the present invention has a liquid cooling module 3 and the liquid cooling head 31 can achieve liquid cooling for the GPU, in order to further reduce the heat dissipation efficiency of the GPU under full load, the detection module 2 also includes an air cooling component 27. The air cooling component 27 is electrically connected to the control module 5 and is mounted on the detection platform 21. The air cooling component 27 includes a fan that faces the GPU on the detection platform 21. When the GPU is undergoing aging detection, the air cooling component 27 enters the working state and provides cooling air to the GPU.

[0076] Furthermore, such as Figures 1 to 11 As shown in the figure, this embodiment proposes that the liquid cooling module 3 also includes a water supply component, which includes:

[0077] Water supply rack 32 is located on the side of aging rack 1 and has a water flow channel;

[0078] The water supply cooling tank 33 is located on the side of the aging frame 1 and is connected to the water supply frame 32 via a water flow channel;

[0079] The water supply hose 34 is connected at one end to the water flow channel of the water supply frame 32 and at the other end to the water supply module.

[0080] Among them, the water supply hose 34 is set up one-to-one with the water supply module.

[0081] In this embodiment, to achieve good circulation and cooling effect of the cooling liquid in the liquid cooling module 3, the water supply assembly includes a water supply rack 32, a water supply cooling tank 33, and a water supply hose 34. The water supply rack 32 is located outside and connected to the aging rack 1, and has a water flow channel inside. The water supply cooling tank 33 is positioned at a certain distance from the aging rack 1, contains cooling water, and can cool the returning cooling water. The water supply cooling tank 33 is connected to the water flow channel in the water supply rack 32. One end of the water supply hose 34 is connected to the water flow channel in the water supply rack 32, and the other end is connected to the water circulation module. The water supply hose 34 includes an inlet pipe and an outlet pipe, and is ultimately used to exchange the coolant between the water supply cooling tank 33 and the liquid cooling head 31.

[0082] Furthermore, such as Figures 1 to 11 As shown, this embodiment proposes a water-passing module including:

[0083] A water inlet 35 is installed on the liquid cooling head 31 and connected to the cooling channel;

[0084] A water-passing bracket 36 is installed on the testing platform 21;

[0085] A rigid water pipe 37 is fixed on a water supply bracket 36. One end of the rigid water pipe 37 is connected to a water supply connector 35, and the other end is connected to the end of a water supply hose 34.

[0086] In this embodiment, to simplify the structure and reduce the overall complexity of the equipment, the water supply module includes a water supply connector 35, a water supply bracket 36, and a water supply rigid pipe 37. The water supply connector 35 is mounted on the liquid-cooled pressure head 31 and connects to the cooling channel within the liquid-cooled pressure head 31. The water supply bracket 36 is mounted on the testing platform 21 and is detachably fixed. The water supply rigid pipe 37 is fixed to the water supply bracket 36, with one end connected to a water supply hose 34 and the other end connected to the water supply connector 35. Since the liquid-cooled pressure head 31 needs to move with the testing platform 21, to ensure reliable connection to the cooling channel, the water supply connector 35 is fitted with a water supply rigid pipe 37. This prevents the water supply connector 35 from loosening due to bending stress, thus ensuring water supply to the liquid-cooled pressure head 31.

[0087] Furthermore, such as Figures 1 to 11 As shown, this embodiment proposes a liquid cooling head 31 including a heat-conducting block 38, which is disposed on the side of the liquid cooling head 31 facing the GPU, with the two sides of the heat-conducting block 38 contacting the cooling channel and the GPU respectively.

[0088] In this embodiment, to further improve heat dissipation efficiency, a heat-conducting block 38 is provided on the surface of the liquid cooling head 31 facing the GPU. The heat-conducting block 38 is in direct contact with the GPU and is made of a metal with good thermal conductivity, such as copper. By setting the heat-conducting block 38, not only can the overall manufacturing cost of the device be greatly reduced, but the heat dissipation effect of the liquid cooling head 31 on the GPU can also be effectively improved.

[0089] Furthermore, such as Figures 1 to 11 As shown, this embodiment proposes a liquid-cooled pressure head 31 including a liquid-cooled base 311, a liquid-cooled cover plate 312 and an elastic element. The liquid-cooled cover plate 312 is disposed on the liquid-cooled base 311, the elastic element is located between the liquid-cooled cover plate 312 and the base, and the cooling channel is located between the liquid-cooled cover plate 312 and the liquid-cooled base 311.

[0090] In this embodiment, to further reduce manufacturing costs and improve heat dissipation efficiency, the liquid-cooled pressure head 31 includes a liquid-cooled base 311, a liquid-cooled cover plate 312, and an elastic element. The liquid-cooled base 311 is mounted on the drive module 4, the liquid-cooled cover plate 312 covers the liquid-cooled base 311, and the elastic element is located between the liquid-cooled cover plate 312 and the liquid-cooled base 311. The liquid-cooled cover plate 312 is used to contact the GPU. Therefore, the elastic element is provided between the liquid-cooled cover plate 312 and the liquid-cooled base 311. The elastic element can reduce the impact force generated when the liquid-cooled cover plate 312 contacts the GPU instantly, thereby protecting the GPU.

[0091] Furthermore, such as Figures 1 to 11 As shown, this embodiment proposes an elastic element including a guide rod 313 and a spring 314. One end of the guide rod 313 is fixedly connected to the liquid cooling base 311, and the other end passes through the liquid cooling cover plate 312. The spring 314 is sleeved on the outside of the guide rod 313, with one end of the spring 314 abutting against the liquid cooling base 311 and the other end abutting against the liquid cooling cover plate 312.

[0092] In this embodiment, to simplify the device, the elastic element includes a guide rod 313 and a spring 314. The first end of the guide rod 313 is connected to the liquid cooling base 311, and the second end of the guide rod 313 passes through the liquid cooling cover plate 312. The spring 314 is sleeved on the outside of the guide rod 313, with one end of the spring 314 abutting against the liquid cooling base 311 and the other end abutting against the liquid cooling cover plate 312. When the liquid cooling cover plate 312 moves toward the liquid cooling base 311, the spring 314 is compressed, thereby reducing the squeezing force between the liquid cooling cover plate 312 and the GPU.

[0093] Furthermore, such as Figures 1 to 11 As shown, this embodiment proposes a driver module 4 including:

[0094] The drive frame 41 is slidably mounted on the detection platform 21 along a straight line, and the drive frame 41 is set in a one-to-one correspondence with the detection platform 21.

[0095] A first driver 42 is disposed within the receiving cavity and has a first driving end, the first driving end being connected to a drive frame 41;

[0096] The second driver 43 is mounted on the drive frame 41 and has a second drive end that moves in the vertical direction. The liquid-cooled pressure head 31 is connected to the second drive end. There are multiple second drivers 43, and each one corresponds to a liquid-cooled pressure head 31.

[0097] In this embodiment, to reduce the overall complexity of the device, the drive module 4 includes a drive frame 41, a first driver 42, and a second driver 43. The drive frame 41 is mounted on the detection platform 21, and the number of drive frames 41 and the detection platform 21 are the same and they are arranged in a one-to-one correspondence. The first driver 42 is mounted in the receiving cavity (or its end can be fixedly mounted on the detection platform 21) and has a first drive end, which is connected to the drive frame 41. The first driver 42 enables the drive frame 41 to move horizontally. The second driver 43 is mounted on the drive frame 41, and the liquid-cooled pressure head 31 is mounted on the second drive end of the second driver 43, thereby enabling the liquid-cooled pressure head 31 to move vertically. The liquid-cooled pressure head 31 moves horizontally and vertically with the help of the first driver 42 and the second driver 43, thereby ensuring that it can adapt to GPUs of different specifications.

[0098] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
