Description

Technical Field

[0001] This utility model relates to the field of immersion liquid cooling box technology, specifically a three-layer stacked automatic pull-out immersion liquid cooling box structure. Background Technology

[0002] With the explosive growth in global demand for high-density computing power, liquid cooling technology has become a core direction for breaking through the bottleneck of traditional air cooling. However, there is no mature solution for three-layer stacked liquid cooling cabinets at home and abroad. Existing technologies are mostly vertical or horizontal fixed structures, and their development paths are significantly different: foreign liquid cooling technology was applied earlier and focused on breaking through the limits of technology by relying on the advantages of materials and processes. It is adapted to ultra-high power GPU clusters such as NVIDIA and AMD. However, because it mainly uses fluorinated liquids and relies on customized servers and precise control algorithms, the system is highly complex and expensive, and it is only used in AI training clusters of large technology giants.

[0003] With the "East Data, West Computing" strategy and the explosive growth in AI computing power demand, China has accelerated the deployment of liquid cooling technology. Cold plate liquid cooling accounts for over 80% of the market, but it is mostly adapted to the renovation of existing data centers (the renovation cost is 30% higher than that of air cooling). The power density of a single rack is 30-50kW, and it also faces the triangular contradiction of "computing power improvement, space limitation, and operation and maintenance costs". It has low space efficiency (standard racks only support 4-6 servers, with a utilization rate of less than 30%), poor compatibility (the server and liquid cooling system are hardware-bound, making it difficult to adapt to heterogeneous GPU clusters), and technical limitations (it only covers some high-power components, while the rest rely on air cooling. Operation and maintenance require frequent emptying of coolant, resulting in high loss rate, which does not meet the requirements of "dual carbon" low energy consumption and low loss.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a three-layer stacked automatic pull-out immersion liquid-cooled cabinet structure, including a cabinet, in which multiple layers of immersion cabinets are slidably connected. Each immersion cabinet has a pull-out switch fixedly installed on its front wall. A return liquid solenoid valve switch is fixedly installed on the front wall of each immersion cabinet at the bottom position corresponding to the pull-out switch. Multiple symmetrically arranged warning light strips are fixedly connected to the front wall of each immersion cabinet. A bracket is fixedly connected inside the cabinet at the back position corresponding to the immersion cabinet. A secondary return liquid pipe and a secondary supply liquid pipe are fixedly connected to the bottom arm of the bracket. A controllable solenoid valve is fixedly installed on the delivery pipe of each secondary supply liquid pipe. Multiple cable management plates are fixedly connected to the upper arm of the bracket. An electric push rod is fixedly installed on the upper arm of the bracket at the back position corresponding to the immersion cabinet. Multiple tank drag chains are fixedly installed on the back of each immersion cabinet. Multiple detachable power strips are fixedly connected to the top of the cabinet.

[0006] Preferably, each of the pull-out switches is electrically connected to a corresponding electric push rod, and each of the return solenoid valve switches is electrically connected to a corresponding controllable solenoid valve.

[0007] Preferably, the output end of each electric push rod is fixedly connected to the back wall of the corresponding immersion chamber.

[0008] Preferably, the other end of each tank drag chain is fixedly connected to a corresponding cable management plate.

[0013] 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.

[0014] Please see Figure 1-3 The present invention provides the following technical solution: A three-layer stacked automatic pull-out immersion liquid-cooled enclosure structure includes a cabinet 1, with multiple immersion enclosures 2 slidably connected inside the cabinet 1. Pull-out switches 3 are fixedly installed on the front wall of each immersion enclosure 2. A return liquid solenoid valve switch 4 is fixedly installed on the front wall of each immersion enclosure 2 at the bottom position corresponding to the pull-out switch 3. Multiple warning light strips 5 are fixedly connected to the front wall of each immersion enclosure 2. A bracket 6 is fixedly connected inside the cabinet 1 at the back position corresponding to the immersion enclosure 2. A secondary return liquid pipe 7 and a secondary supply liquid pipe 8 are fixedly connected to the bottom arm of the bracket 6. A controllable solenoid valve 9 is fixedly installed on the delivery pipe of the secondary supply liquid pipe 8. Multiple cable management boards 10 are fixedly connected to the upper arm of the bracket 6. An electric push rod 11 is fixedly installed on the upper arm of the bracket 6 at the back position corresponding to the immersion enclosure 2. Multiple tank drag chains 12 are fixedly installed on the back of each immersion enclosure 2. Multiple detachable power strips 13 are fixedly connected to the top of the cabinet 1.

[0015] Pull-out switches 3 are all electrically connected to the corresponding electric push rods 11. Pull-out switches 3 facilitate intelligent control of the electric push rods 11 to open and close flexibly. Return solenoid valve switches 4 are all electrically connected to the corresponding controllable solenoid valves 9. The output ends of the electric push rods 11 are all fixedly connected to the back wall of the corresponding submersible tank 2. The electric push rods 11 facilitate the extension or retraction of the submersible tank 2. The other end of the tank drag chain 12 is fixedly connected to the corresponding cable management plate 10. The tank drag chain 12 facilitates the support of the submersible tank 2. There are three delivery pipes on the secondary return pipe 7, which are fixedly connected to and pass through the corresponding submersible tank 2. There are three delivery pipes on the secondary supply pipe 8, all of which are corrugated pipes, and one end of each delivery pipe is fixedly connected to and passes through the corresponding submersible tank 2.

[0016] In use, the corresponding electric push rod 11 is activated by the corresponding pull-out switch 3. The extended output end of the electric push rod 11 will move the corresponding immersion enclosure 2 towards the outside of the cabinet 1. The movement of the immersion enclosure 2 will pull one end of the tank chain 12, causing it to gradually straighten. After the immersion enclosure 2 is opened, five 6U high-performance GPU servers can be placed inside. After placement, the immersion enclosure 2 can be reset to its original position using the pull-out switch 3 and the electric push rod 11. The external CDU unit is activated, and the primary and secondary circulation pumps drive the flow of ethylene glycol solution and synthetic oil, respectively. The secondary synthetic oil flows through... The secondary liquid supply pipe 8 enters, and the corresponding controllable solenoid valve 9 is activated by the return solenoid valve switch 4. At this time, the synthetic oil can enter the corresponding immersion chamber 2 through the corrugated conveying pipe of the secondary liquid supply pipe 8, immerse the server and absorb the heat of the chip. After absorbing the heat, the synthetic oil flows out through the secondary return pipe 7 and enters the plate heat exchanger of the external CDU unit. It exchanges heat with the primary side ethylene glycol solution and releases heat. After absorbing the heat, the primary side ethylene glycol solution flows to the outdoor heat exchanger. The heat is dissipated to the atmosphere by the cooling tower fan and spray water. After cooling down, it flows back to the plate heat exchanger to complete the cycle. During normal operation, the warning light strip 5 is blue.
