As shown in FIG. 1 , an embodiment of the present disclosure provides a liquid cooling cabinet, including: a cold plate type liquid cooling server 2 , including a cabinet body 100 and a cooling liquid circulation component. The cabinet body 100 is formed with a accommodating cavity, and The bottom surface of the cavity is provided with a mounting plate 200. The mounting plate 200 is used to fix the cold plate type liquid cooling server 2; The liquid port 10, the liquid return port 20, the branch liquid supply port 30 and the branch liquid return port 40, the flow channels include the liquid supply flow channel 50, the liquid return flow channel 60, the liquid supply branch 70 and the liquid return branch 80; The liquid supply port 10 is used to connect the water outlet of the cooling liquid supply device, the liquid return port 20 is used to connect to the water inlet end of the cooling liquid supply device, and the liquid supply branch 70 communicates with the liquid supply channel 50 and the branch liquid supply interface. 30. The liquid return branch 80 communicates with the return flow channel 60 and the branch liquid return port 40. The branch liquid supply port 30 is used to connect the water inlet pipe of the liquid cooling plate of the cold plate type liquid cooling server 2, and the branch liquid return port 40 Outlet pipe for connection to liquid cooling plate.

In this embodiment, the flow path of the cooling liquid in the liquid cooling cabinet includes a main circuit and various branch circuits, wherein the liquid supply interface 10 of the liquid cooling cabinet is connected with the water outlet of the liquid cooling supply device (for example, a CDU), so as to connect the The cooling liquid is connected to the cooling liquid circulation component of the liquid cooling cabinet. The liquid return interface 20 is connected with the water inlet end of the liquid cooling supply device, so that the cooling liquid after absorbing heat flows back to the cooling liquid supply device to form a main circuit for the circulation of the cooling liquid. At the same time, each cold plate type liquid cooling server 2 is simultaneously connected to a branch liquid supply port 30 and a branch liquid return port 40 to form a cooling liquid circulation branch. The cooling liquid in the liquid supply channel 50 flows into the return liquid channel 60 through each branch to form a circuit in which the cooling liquid circulates.

Specifically, the circulation circuit of the cooling liquid in this embodiment is as follows: the water outlet end of the cooling liquid supply device flows into the liquid supply channel 50 through the liquid supply port 10 , and then flows into the cooling liquid from the branch liquid supply port 30 through the liquid supply branch 70 . The water inlet pipe of the liquid-cooling plate of the plate-type liquid-cooling server 2 flows into the liquid-cooling plate of the cold-plate liquid-cooling server 2, and the heat emitted by the chip of the cold-plate liquid-cooling server 2 is absorbed by the cooling liquid circulating in the liquid-cooling plate. The cooling liquid after absorbing heat flows out from the water outlet pipe of the liquid cooling plate, flows into the liquid return channel 60 through the liquid return port 40 of the branch, and then flows back to the cooling liquid supply device through the liquid return port 20 .
