Abstract
Description
Technical Field
[0001] This utility model relates to the field of multi-GPU BOX technology, and in particular to a multi-GPU BOX based on Retimer. Background Technology
[0002] With the rapid growth of artificial intelligence, high-performance computing, and massively parallel processing tasks, the demand for GPU computing power continues to rise. Traditional server or workstation designs typically integrate the CPU with multiple GPU modules in the same chassis to meet the needs of compute-intensive applications. However, this centralized design has gradually revealed many limitations when faced with ultra-high-density GPU deployments. High-power, high-density GPUs, especially those supporting the Triple-slot design, generate enormous heat under heavy loads. In the compact traditional chassis, the airflow path is complex and the space is divided by components such as the CPU, storage, and power supply, making it difficult to dissipate heat quickly and effectively. This can easily cause the GPU to throttle or even be damaged due to overheating, seriously affecting system stability and sustained performance output. Simply relying on the chassis's built-in air cooling often fails to achieve the ideal state. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies where relying solely on internal air cooling in the chassis often fails to achieve the desired performance, and to provide a multi-GPU BOX based on Retimer.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a multi-GPU BOX based on Retimer, comprising a chassis, a filter plate fixedly connected to one side of the chassis, multiple filter holes opened on the top of the chassis, a mounting plate provided on the inner wall of the chassis, a fixing hole opened on one side of the mounting plate, ten main bodies installed on the inner wall of the fixing hole, multiple brackets fixedly connected to the bottom of the mounting plate, a mounting hole opened on one side of the brackets, and water cooling pipes fixedly connected between the inner walls of the multiple mounting holes.
[0005] In a preferred embodiment, a water-cooled box is installed on the inner wall of the chassis, and the output end and input end of the water-cooled box are fixedly connected to the two ends of the water-cooling pipe, respectively.
[0006] In a preferred embodiment, a support plate is fixedly connected between the bottoms of the plurality of brackets, and a limiting hole is provided on one side of the support plate.
[0007] In a preferred embodiment, the inner wall of the limiting hole is fixedly connected to two first baffles, and the inner wall of the limiting hole is fixedly connected to a second baffle.
[0008] In a preferred embodiment, multiple support holes are provided on one side of both the first baffle and the second baffle, and multiple fan mechanisms are provided on the inner wall of the limiting hole.
[0009] In a preferred embodiment, the fan mechanism has a plurality of connection holes on one side that are adapted to the support holes.
[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention utilizes a filter plate and filter holes to effectively filter dust and increase airflow, preventing dust from entering the chassis and improving the overall efficiency of the cooling system. The combination of water-cooling pipes and a water-cooling box achieves efficient heat dissipation for the main unit. The circulating water system removes heat generated by the GPU, preventing performance degradation or hardware damage due to overheating. The fan mechanism and bracket enhance the cooling effect of the water-cooling pipes, with the fan blowing air through them to improve cooling efficiency and ensure the device remains at a stable operating temperature. The bracket, first baffle, and second baffle design effectively guide airflow, enhancing heat dissipation. The baffles help restrict the direction of airflow, ensuring the fan output air passes accurately through the water-cooling pipes and the main unit for more efficient cooling. The fan mechanism, along with the support holes and connection holes, ensures a stable connection between the fan, the bracket, and other components, making the entire cooling system more robust and stable, preventing uneven heat dissipation or malfunctions during prolonged use. Through the coordinated operation of the fan mechanism and water cooling pipes, the GPUBOX features an optimized internal space design. The mounting plate provides at least 10 PCIe x16 physical slots and is compatible with triple-slot GPU cards. The slots have sufficient spacing and airflow channels to support the heat dissipation of high-power GPU cards. The efficient independent cooling solution can use high-volume fans, liquid cooling modules, or a combination of both to ensure the heat dissipation requirements of high-density GPUs under heavy loads. When used with appropriate components, the following effects can be achieved: 1. Extreme GPU density: By removing the CPU module, the internal space of the GPUBOX is maximized, supporting 10 three-width GPUs, which greatly improves the computing power density of a single chassis and reduces the space occupied per unit of computing power.
[0011] 2. Superior signal integrity: The introduction of a Retimer chip effectively overcomes the attenuation and noise problems in high-speed PCIe signal transmission, ensuring the reliability and high performance of data transmission between the GPUBOX and the external CPU module, especially suitable for PCIe Gen5 / Gen6 and higher generation applications.
[0012] 3. Flexible deployment: The independent GPUBOX design allows for separate deployment from the CPU module, which helps optimize rack space layout and enables independent upgrades and maintenance of the CPU and GPU.
[0013] 4. Optimized heat dissipation and power supply: The pure GPU design allows the heat dissipation and power supply system to be optimized entirely around the characteristics of the GPU, managed independently, and improving the overall system stability and lifespan.
[0014] 5. Reduced operating costs: Higher computing density means fewer server racks and lower energy consumption, thereby reducing the operating costs of data centers.
[0015] High versatility: The independent GPUBOX can be used with different CPU modules, improving the system's versatility and compatibility. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example like Figure 1-4 As shown, this utility model provides a technical solution: a multi-GPU BOX based on Retimer, including a chassis 1, a filter plate 2 fixedly connected to one side of the chassis 1, multiple filter holes 3 opened on the top of the chassis 1, a mounting plate 5 provided on the inner wall of the chassis 1, a fixing hole 6 opened on one side of the mounting plate 5, ten main bodies 7 installed on the inner wall of the fixing hole 6, multiple brackets 8 fixedly connected to the bottom of the mounting plate 5, a mounting hole 15 opened on one side of the brackets 8, and water cooling pipes 9 fixedly connected between the inner walls of the multiple mounting holes 15. A water-cooled box 4 is installed on the wall. The output end and input end of the water-cooled box 4 are fixedly connected to the two ends of the water-cooled pipe 9, respectively. A support plate 10 is fixedly connected between the bottoms of multiple brackets 8. A limit hole is opened on one side of the support plate 10. Two first baffles 11 are fixedly connected to the inner wall of the limit hole. A second baffle 12 is fixedly connected to the inner wall of the limit hole. Multiple support holes 14 are opened on one side of the first baffle 11 and the second baffle 12. Multiple fan mechanisms 13 are provided on the inner wall of the limit hole. Multiple connection holes that are adapted to the support holes 14 are opened on one side of the fan mechanism 13. Through the above embodiments, the design of filter plate 2 and filter holes 3 effectively filters dust and increases air circulation, preventing dust from entering the chassis 1 and improving the overall efficiency of the heat dissipation system. The water cooling pipe 9 and water cooling box 4 work together to achieve efficient heat dissipation of the main body 7. The heat generated by the GPU main body 7 is carried away by the circulation of the water cooling system, avoiding performance degradation or hardware damage due to excessive temperature. The cooperation of fan mechanism 13 and bracket 8 enhances the heat dissipation effect of water cooling pipe 9. The fan blows air through water cooling pipe 9 to improve the water cooling effect and ensure that the device is kept at a stable operating temperature. The design of bracket 8, first baffle 11 and second baffle 12 effectively guides air flow and enhances the heat dissipation effect. The baffle helps to limit the direction of air flow and ensures that the air output by the fan can accurately pass through water cooling pipe 9 and main body 7 to achieve a more efficient cooling effect. The cooperation of fan mechanism 13 with support hole 14 and connection hole ensures stable connection between fan and bracket 8 and other components, making the entire heat dissipation system more robust and stable, and avoiding uneven heat dissipation or failure during long-term use of the device. With the fan mechanism 13 and water cooling pipe 9 working together, the internal space design of the GPUBOX is optimized. At the same time, the mounting plate 5 provides at least 10 PCIe x16 physical slots and is compatible with triple-slot GPU cards. There is sufficient spacing and airflow channels between the slots to support the heat dissipation of high-power GPU cards. The efficient independent heat dissipation solution can use a high-volume fan, liquid cooling module or a combination of both to ensure the heat dissipation requirements of high-density GPUs under heavy loads in the case. The introduction of a Retimer chip effectively overcomes the attenuation and noise problems in high-speed PCIe signal transmission, ensuring the reliability and high performance of data transmission between the GPUBOX and the external CPU module, especially suitable for PCIe Gen5 / Gen6 and higher generation applications; The independent GPUBOX design allows for separate deployment from the CPU module, which helps optimize rack space layout and enables independent upgrades and maintenance of the CPU and GPU. The pure GPU design allows the cooling and power supply systems to be optimized and managed independently around the characteristics of the GPU, improving the overall system stability and lifespan. The standalone GPUBOX can be used with different CPU modules, improving the system's versatility and compatibility.
[0023] Working principle: like Figure 1-4 As shown, a filter plate 2 is fixedly connected to one side of the chassis 1, and multiple filter holes 3 are opened on the top. The design of the filter plate 2 and filter holes 3 facilitates air circulation, improves heat dissipation efficiency, and prevents dust from entering the chassis 1. A mounting plate 5 is set on the inner wall of the chassis 1. The mounting plate 5 has multiple fixing holes 6. Ten main bodies 7 are installed on the inner wall of the mounting holes 15. Multiple brackets 8 are fixedly connected to the bottom of the mounting plate 5. Mounting holes 15 are opened on one side of the brackets 8. Water cooling pipes 9 are fixedly connected between the multiple mounting holes 15. The water cooling pipes 9 are connected to the input and output ends of the water cooling box 4 inside the chassis 1. The circulating water carries away the heat generated by the main body 7, realizing effective heat dissipation. Inside the chassis 1 The wall is also equipped with multiple fan mechanisms 13. Each fan mechanism 13 has multiple connection holes on one side that are adapted to the support holes 14. These fans work in conjunction with the water cooling pipes 9 and the main body 7. The fans draw in external air and blow it onto the water cooling pipes 9 and the main body 7, thereby enhancing the heat dissipation effect of the water cooling pipes 9 and helping the heat of the entire system to be quickly dissipated, maintaining the normal operating temperature of the equipment. Support plates 10 are fixedly connected between multiple brackets 8. A limiting hole is opened on one side of the support plate 10. A first baffle 11 and a second baffle 12 are fixedly connected to the inner wall of the limiting hole. The design of these baffles can effectively restrict and guide the airflow, ensuring that the fans can accurately deliver air to the area that needs to be cooled.
