[0002] With the continuous increase in GPU / CPU computing power density, existing liquid-cooled workstation chassis face multiple technical bottlenecks:

[0003] 1. The traditional single power supply rear-mounted design results in insufficient power supply redundancy in high-power scenarios, and there is spatial interference between the power supply heat dissipation path and the liquid cooling pipeline;

[0004] 2. Forced air cooling systems generate additional air resistance due to the dust filter structure, and after long-term use, dust blockage further exacerbates the reduction in heat dissipation efficiency;

[0005] 3. Fixed liquid cooling piping connection method requires the entire cooling system to be disassembled for hardware maintenance, which significantly increases operation and maintenance costs.

[0006] Furthermore, the electromagnetic shielding performance of conventional chassis is insufficient to meet the EMC requirements of multi-GPU parallel computing. To address these issues, there is an urgent need for a chassis system solution that integrates power supply redundancy, efficient heat dissipation, and rapid maintenance. To overcome the shortcomings of the existing technologies, this application proposes a liquid-cooled workstation chassis. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0028] Reference Figure 1-2 A liquid-cooled workstation chassis includes a chassis shell 1, an air duct guide groove 2 on the top of the chassis shell 1, a fan 11 below the air duct guide groove 2, a power supply 3, a water distributor 6, a water tank 7 and a water pump 8 installed on the rear side inside the chassis shell 1, and a radiator 9 installed on the upper side inside the chassis shell 1 and below the air duct guide groove 2.

[0029] The CPU cooling plate 4 and GPU cooling plate 5 are installed inside the chassis shell 1;

[0030] A water pump 8 is installed on the water tank 7, and the water tank 7 is connected to the water distributor 6 through the water tank distributor connecting pipe 71;

[0031] Water distributor 6 is connected to cold radiator 9 through water distributor cold radiator connecting pipe 61;

[0032] The radiator 9 is connected to the water tank 7 via a cold water drain tank connecting pipe 91;

[0033] The water distributor 6 is connected to the CPU cold plate 4 via the CPU cold plate inlet pipe 42, and the CPU cold plate 4 is connected to the water distributor 6 via the CPU cold plate return pipe 43.

[0034] Water distributor 6 is connected to GPU cold plate 5 via GPU cold plate inlet pipe 51; GPU cold plate 5 is connected to water distributor 6 via GPU cold plate return pipe 52.

[0035] Furthermore, power supply 3 is provided in two sets.

[0036] Furthermore, water pump 8 is equipped with two sets.

[0037] Furthermore, the CPU cold plate 4 is provided in two sets, and the two sets of CPU cold plates 4 are connected by a CPU cold plate connecting pipe 41. One set of CPU cold plates 4 is connected to the water distributor 6 through a CPU cold plate return water pipe 43, and the other set of CPU cold plates 4 is connected to the water distributor 6 through a CPU cold plate inlet pipe 42.

[0038] Furthermore, the GPU cold plate 5 is provided in four groups, and each group of GPU cold plates 5 is connected to the water distributor 6 through the GPU cold plate inlet pipe 51 and the GPU cold plate return pipe 52 respectively.

[0039] Furthermore, the CPU cold plate inlet pipe 42, the CPU cold plate return pipe 43, the GPU cold plate inlet pipe 51, and the GPU cold plate return pipe 52 are respectively connected to the water distributor 6 via UQD02 quick connector 10.

[0040] This application includes a water distributor 6, a UQD02 quick connector 10 and flexible piping, a water pump 8, a water tank 7, a radiator 9, a fan 11 and a power supply 3, which are connected to the CPU cold plate 4 and the GPU cold plate 5.

[0041] The power supply adopts T+1 mode, which ensures the power supply temperature while being able to run multiple high-power graphics cards without any pressure.

[0042] The water pump adopts the T+1 mode and defaults to series operation. This ensures that if one pump fails, the other pump can still operate normally, guaranteeing normal heat dissipation of the liquid cooling system. It also increases the pump head on the basis of a single pump, ensuring that the entire liquid cooling system can operate smoothly without pressure.

[0043] The entire liquid-cooled workstation uses quick-connect fittings to connect the CPU / GPU cold plates, which facilitates future product maintenance and reduces maintenance costs. The quick-connect fitting model is UQD02, which can meet the flow requirements of a single cold plate.

[0044] Depending on whether it's a single-channel or dual-channel motherboard, the water distributor uses either a 5-hole or 6-hole distributor. The distributor distributes the liquid in the tank in parallel to the CPU / GPU cold plates, ensuring that each card receives a consistent flow rate, thereby ensuring consistent heat dissipation and power consumption for the CPU / GPU and reducing risks.

[0045] CPU cooler plate 4 is made of pure aluminum / aluminum and copper to dissipate heat from the CPU;

[0046] GPU Cooler 5 is made of pure aluminum / pure copper / aluminum and copper materials to dissipate heat from the GPU;

[0047] The radiator 9 comes in sizes such as 360 / 480 / 420 and uses a dual radiator configuration to enhance heat dissipation. The fan is a 12cm fan with a speed of 1500-3000 RPM, designed for low decibel and quiet operation.

[0048] Chassis principle:

[0049] Liquid is filled through the water tank 7. After filling, the liquid is driven by the water pump 8 to flow into the distributor 6. The liquid is then split in parallel through the distributor 6 to the CPU cold plate inlet pipe and the GPU cold plate inlet pipe. The inlet pipes are connected by UQD02 quick connectors 10. The liquid undergoes heat exchange with the CPU cold plate and the GPU cold plate, carrying away the heat generated by the CPU / GPU operation. If the CPU side has a single cold plate, the liquid returns to the distributor 6 through the CPU cold plate 4 after heat exchange. If it has a dual cold plate, the liquid flows into the CPU cold plate after heat exchange, continues to undergo heat exchange, and then returns to the distributor 6. The GPU cold plate also undergoes heat exchange before returning to the distributor 6. The liquid is then collected through the distributor 6 and flows into the radiator 9. There are two radiators 9 connected in series. The liquid flows from one radiator 9 to the other radiator 9, and the heat is carried away by the fan 11 and the air duct guide channel 2. Then the liquid returns to the water tank 7 to complete a heat dissipation cycle.
