Therefore, the features with "first" and "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the fact that a person skilled in the art can realize it, and when the combination of technical solutions contradicts each other or cannot be realized, it should be considered that the combination of technical solutions does not exist, and is not within the scope of protection required by the present application.

[0032] Specifically, as Figures 1 to 3As shown, the present invention proposes the following technical solution: a liquid-cooled UPS cabinet structure, including a cabinet 10, wherein at least two adjacent rows of first load-bearing units 20 and second load-bearing units 30 are arranged inside the cabinet 10; the first load-bearing unit 20 includes several layers of first load-bearing plates 21 arranged from top to bottom, and the second load-bearing unit 30 includes several layers of second load-bearing plates 31 arranged from top to bottom; the first load-bearing plates 21 and the second load-bearing plates 31 are arranged in a one-to-one correspondence, and the one-to-one correspondence between the first load-bearing plates 21 and the second load-bearing plates 31 is on the same horizontal plane;

[0033] Each of the first load-bearing plates 21 is provided with a first liquid cooling pipe 40; each of the second load-bearing plates 31 is provided with a second liquid cooling pipe 50; the first liquid cooling pipe 40 and the second liquid cooling pipe 50, which are on the same horizontal plane, are connected by a connecting bend 60.

[0034] This application's structure, by setting a first liquid cooling pipe and a second liquid cooling pipe on each load-bearing plate and connecting the first and second liquid cooling pipes on the same horizontal plane, allows the heat from the module to be directly absorbed and carried away through the bottom liquid cooling pipe during high-rate discharge of the module, thus achieving effective cooling of the entire cabinet. At the same time, it also eliminates the conventional liquid cooling plate structure, simplifies the manufacturing process, improves the aesthetic performance of the module, and effectively reduces manufacturing and usage costs.

[0036] In a preferred embodiment, one end of the connecting bend 60 is connected to the outlet of the first liquid cooling pipe 40, and the other end is connected to the inlet of the second liquid cooling pipe 50.

By providing the first insulating cotton, condensation can be effectively prevented on the connecting bend, the first liquid cooling pipe, and the second liquid cooling pipe while ensuring heat dissipation.

[0039] As a preferred embodiment, the first liquid cooling pipe 40 and the second liquid cooling pipe 50 are both serpentine liquid cooling pipes; the first liquid cooling pipe 40 is arranged in abutment with the first load-bearing plate 21, and the second liquid cooling pipe 50 is arranged in abutment with the second load-bearing plate 31.
