Description

Technical Field

[0001] This utility model relates to the field of liquid-cooled server technology, and in particular to a wiring structure inside a liquid-cooled server cabinet. Background Technology

[0002] The current trend is that existing data centers will upgrade to liquid cooling within the next five years. The best replacement process for liquid-cooled cabinets is in-situ replacement, which means not changing the usual layout, i.e., 8 cabinets per row. Assuming 125A per cabinet, that's 1000A, and considering some redundancy, it's 1250A.

[0003] Because the busbars and junction boxes of this specification are large in size, and the double busbar cabinet is installed on the top, with a junction box required every 600mm, it is difficult for the existing busbar system to make effective use of this space. Even if it is installed, the inspection and maintenance will be difficult because the junction boxes of the two busbars are located in front of each other or vertically.

[0004] Therefore, technical personnel in related industries believe that this issue should be taken into account when designing this cabinet, and that a dedicated nine-core copper busbar system is necessary to adapt to the evolving needs of data center infrastructure that is now focused on AI computing. Utility Model Content

[0005] The purpose of this invention is to provide a wiring structure inside a liquid-cooled server cabinet to solve the problems existing in the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A wiring structure for a liquid-cooled server cabinet includes a server. Multiple sets of liquid-cooled computing modules are arranged at equal intervals from top to bottom inside the server. Each liquid-cooled computing module has a copper busbar inside the server, and each liquid-cooled computing module is electrically connected to the copper busbar via a circuit breaker. A wiring module is fixedly installed on the top of the server. The wiring module includes a dual-channel control switch, a junction box, and a nine-core busbar. The nine-core busbar is electrically connected to the dual-channel control switch, which splits the nine-core busbar into two lines. The two split lines are electrically connected to the junction box, and the junction box is electrically connected to the copper busbar.

[0008] By adopting the above technical solution, the computing system and liquid cooling system are powered by dual lines respectively, which reduces the mutual interference between the power supply systems and enables the internal heat dissipation system and computing system of the server to have a stable circuit connection foundation.

[0009] In a further embodiment, the server includes a cabinet and a mounting rack disposed inside the cabinet, with multiple sets of the liquid-cooled computing modules arranged at equal intervals from top to bottom on the mounting rack.

[0010] In a further embodiment, the copper busbar is located on the inside right side of the cabinet.

[0011] By adopting the above technical solution, an inspection door is opened on the right side of the cabinet, so that the position of the copper busbar corresponds to the position of the inspection door, which facilitates both wiring connection and maintenance.

[0012] In a further embodiment, the dual-channel control switch is a control switch having two switch controllers.

[0013] The above technical solution is used to split the nine-core busbar into two lines.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. By using dual power lines to supply power to the computing system and the liquid cooling system respectively, the mutual interference between the power supply systems is reduced, which ensures that both the internal heat dissipation system and the computing system of the server have a stable circuit connection foundation for operation.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to the attached figures. Figure 1 In this specification, the terms "bottom surface" and "top surface," "inner" and "outer" refer to the direction toward or away from the geometry of a specific component. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0021] Example 1:

[0022] like Figures 1-2 As shown, a wiring structure for a liquid-cooled server cabinet includes a server 1. Multiple sets of liquid-cooled computing modules are arranged at equal intervals from top to bottom inside the server 1. Each liquid-cooled computing module has a copper busbar 2 inside the server 1, and each liquid-cooled computing module is electrically connected to the copper busbar 2 via a circuit breaker. A wiring module is fixedly installed on the top of the server 1. The wiring module includes a dual-channel control switch, a junction box, and a nine-core busbar. The nine-core busbar is electrically connected to the dual-channel control switch, which splits the nine-core busbar into two lines. The two split lines are electrically connected to the junction box, which is electrically connected to the copper busbar 2. The server 1 includes a cabinet and a mounting frame inside the cabinet. Multiple sets of liquid-cooled computing modules are arranged at equal intervals from top to bottom on the mounting frame. The copper busbar 2 is located on the right side inside the cabinet. The dual-channel control switch is a control switch with two switch controllers.

[0023] Specific implementation process: By using dual lines to power the computing system and liquid cooling system respectively, the mutual interference between the power supply systems is reduced, ensuring that both the internal heat dissipation system and computing system of the server have a stable circuit connection foundation. The nine cores of the nine-core power transmission bus are named AN, AL1, AL2, AL3, GND, BN, BL1, BL2, and BL3, respectively. GND is electrically connected to the first conductor. The four connecting lines on one connecting block are connected to AN, AL1, AL2, and AL3 respectively, and the four connecting lines on another connecting block are connected to BN, BL1, BL2, and BL3 respectively, thus realizing the circuit modification. Since a dual-circuit control switch is used in this scheme, the number of terminals of the dual-circuit control switch must be even. Since the ground wires can be connected together, one set of terminals is connected in series with GND, thus realizing the basic structure of the nine-core power transmission bus.

[0024] It should be noted that the server in this technical solution is the infrastructure for 4U rack-mount servers. Its main body is a rectangular frame cabinet. In addition to having a standard structure that can support the weight of 10 4U 19-inch servers with a maximum depth of 900mm, this cabinet also has two 125A~160A power supplies (divided into 2*10*3*16A), as well as a minimum 55kW (10*10*500W interface) balanced liquid cooling and a minimum 10kW air cooling intelligent heat dissipation system.

[0025] Example 2:

[0026] A 47U 19-inch server rack module system with an energy density of 65kW~130kW. It consists of the following 7 parts:

[0027]

[0028] Their respective functions and interrelationships are as follows:

[0029] 1. Rack: The rack is a standard 47U 19-inch server, 600mm wide, 2200mm high, and 1200mm deep. The outer structural frame is the structural support for all components.

[0030]

[0031] 2. Intelligent redundant power transmission and distribution module

[0032]

[0033] 3. Intelligent control module

[0034]

[0035] 4. Liquid-cooled equalization solution preparation module

[0036]

[0037] 5. Liquid-cooled heat exchanger and drive module

[0038]

[0039] 6. Intelligent air-cooling module

[0040]

[0041] 7. Air-cooled heat exchange module

[0042]

[0043] This solution, through proper allocation of space within a 47U 19-inch rack, achieves redundant power supply, 10*10 chip-level balanced liquid cooling, and redundant air cooling to absorb the remaining cooling load, all within a shielded rack. This system not only provides a reliable operating environment and resources for 10 standard rack-mount 4U high 2CPU+8GPU servers but also ensures a safe internal environment (non-open rack). The system connects to a higher-level host computer system via fiber optic Ethernet. The host computer statistically analyzes the energy consumption space state equations of the rack operation to extract the correspondence between the control parameter set and the system state set, thereby autonomously finding the optimal energy efficiency model. After careful verification by engineers, the system's energy efficiency level can be continuously upgraded iteratively without updating hardware configurations.
