Description
Technical Field

[0002] With the explosive growth in demand for cloud computing, artificial intelligence, and high-performance computing, data centers are developing towards ultra-high density and ultra-large scale. However, traditional server architectures face three core bottlenecks in the process of increasing computing density: heat dissipation efficiency, energy consumption, and interconnect bandwidth. In terms of heat dissipation, traditional air cooling has approached its physical limits, while existing liquid cooling technology is more efficient, but its complex piping connection and maintenance process is cumbersome, making it difficult to achieve fast and non-destructive hot-swapping, which seriously restricts the efficiency of operation and maintenance. In terms of electrical interconnection, wired connections that rely on physical connectors not only become a bottleneck for data transmission rates, but their mechanical wear also affects the reliability of long-term connections. Furthermore, a large number of cables occupy valuable space, hindering further increases in device density.

[0025] Example 2:
[0026] Please see Figures 1-8 The present invention discloses an ultra-high density server chassis system based on liquid cooling. Compared with Embodiment 1, this embodiment further includes: a flow guiding component 7 comprising a quick connector 71 inserted and fixed to a connecting pipe on the inner wall of the main chassis 1; the quick connector 71 is fixedly disposed at the inlet and outlet of a loop pipe 72, and the loop pipe 72 is fixedly disposed inside a protective housing 73; a sensor 74 with data acquisition function is inserted and fixedly disposed on the top side of the loop pipe 72; photoelectric sensors 75 with data acquisition function are disposed on both sides inside the protective housing 73; the quick connector 71 of the flow guiding component 7 is connected to the circulation loop of the connecting pipe on the inner wall of the main chassis 1; the sensor 74 is used to monitor the temperature and / or pressure data of the coolant flowing through the loop pipe 72 in real time and transmit the data to the control system 4.
[0027] The working principle of the above-mentioned ultra-high-density server chassis system based on liquid cooling is as follows: First, when using this device, place it in the work area, and then connect it to an external power source to provide the power required for its operation. Second, the operator pushes the server chassis 3 into the host chassis 1 along the track mounting piece 2. Here, the operator needs to connect and lock the quick connector 71 to the pre-installed liquid cooling pipeline system inside the host chassis 1 to form a closed coolant circulation loop. At the same time, through the guide post 84 of the fixed transmission piece 8 fixed on the liquid cooling component 6, it begins to slide into the conical guide groove 54 of the movable transmission piece 5 fixed on the host chassis 1, completing the primary positioning and correcting the positional deviation between the server node and the host chassis with millimeter-level accuracy. Third, after the server chassis 3 completes its initial positioning, the annular permanent magnet 82 on the fixed transmission component 8 and the coil array 52 on the floating substrate 51 enter the effective magnetic path. By supplying power to the coil array 52, a strong attractive force is generated on the floating substrate 51. Under the action of magnetic force, the floating substrate 51 will overcome the compression spring resistance of the adjustment component 55 and generate adaptive small displacement and deflection, ensuring that its surface is absolutely parallel and in contact with the surface of the fixed transmission component 8. When the coil array 52 and the annular permanent magnet 82 are tightly in contact, the lens array 83 and the photoelectric transmitter array 53 form extremely short and precisely aligned free space optical paths, completing and realizing the simultaneous establishment of high-speed data optical transmission and power supply, without any physical contact points or cable plugging and unplugging throughout the process. Fourth, the control system 4 then powers the electromagnetic spring 66. The thrust generated by the electromagnetic spring 66 pushes the displacement cold plate 63 to slide into the server within the limiting frame 64, causing the microfins 67 on its surface to be tightly pressed onto the main heat-generating components such as the CPU and GPU. This allows the heat from the heat-generating components to pass through the microfins 67, the displacement cold plate 63, the flexible heat exchange tube 62, and the fixed cold plate 61, ultimately entering the flow guide assembly 7 for heat detection. The heat is then carried away by the material pipe on the inner wall of the main unit chassis 1. The sensor 74 monitors the temperature and pressure of the coolant in real time, and the photoelectric sensor 75 may be used to confirm whether the displacement cold plate is in place. Based on this data and the server load, the control system 4 dynamically adjusts the flow rate and velocity of the coolant to achieve precise heat dissipation. When the server needs maintenance or is under extremely low load, the control system 4 can cut off the power to the electromagnetic spring 66. The spring returns to its original position, and the displacement cold plate 63, carrying the microfins 67, separates from the heat-generating components, facilitating safe hot-swapping or reducing system energy consumption.
[0028] This invention provides an improved ultra-high-density server chassis system based on liquid cooling. Through magnetic adaptive bonding technology, it ensures the absolute parallelism of the optical transmission interface, establishes a high-speed, wear-free free-space optical path, actively presses the cold plate and chip together to achieve tight heat conduction, and dynamically adjusts the coolant flow rate according to real-time load and temperature to achieve precise on-demand heat dissipation. The cold plate can automatically separate from the chip, ensuring operational safety and effectively reducing system standby power consumption, thereby improving the overall operation and maintenance efficiency, reliability, and energy efficiency of the data center.
