Description

Technical Field

[0001] The utility model relates to the CDU field, in particular to a modular CDU cabinet. Background Art

[0002] In the existing liquid cooling solutions, especially for the design of CDU (Cooling Distribution Unit) liquid cooling cabinets, there are generally problems of initial design solidification and poor scalability. Specifically, CDU liquid cooling cabinets often need to be accurately designed and customized in advance according to the specific power requirements of the server cabinet, including key internal components such as plate heat exchangers (plate heat exchangers), water pumps and other hardware configurations, in which the heat of the liquid in the secondary side pipeline is transferred to the liquid in the primary side pipeline through the plate heat exchanger, and the liquid in the primary side pipeline transfers the heat to the outside. Once the system is installed, due to the fixed design of these core components, the entire liquid cooling system cannot be flexibly adjusted or expanded in capacity according to the actual subsequent operation conditions. This inflexible design limits the scalability and future adaptability of the data center. When business needs increase or technology upgrades cause changes in power requirements, the entire liquid cooling system may need to be reconstructed, which undoubtedly increases the cost of maintenance and upgrades, and may cause unnecessary downtime and poor convenience.

In actual use, the heat of the liquid in the secondary side pipeline is transferred to the liquid in the primary side pipeline through the plate exchanger, and the liquid in the primary side pipeline transfers the heat to the outside. Furthermore, the secondary side pipeline usually refers to a server that generates heat during operation. The liquid in the secondary side pipeline will perform heat exchange with the server, thereby reducing the heat of the server. Subsequently, the liquid in the secondary side pipeline will further flow to the CDU cabinet 10 and perform heat exchange with the liquid in the primary side pipeline, so that the heat of the liquid in the secondary side pipeline is transferred to the liquid in the primary side pipeline, thereby allowing the liquid in the secondary side pipeline to be cooled. The cooled liquid in the secondary side pipeline will flow back to the server to cool the server again.

[0031] like Figures 1 to 4As shown, the CDU cabinet 10 includes a cabinet body 1 and a liquid cooling device 2, and the liquid cooling device 2 is arranged on the cabinet body 1.

[0035] It can be understood that the number of liquid cooling modules 21 can be flexibly set, specifically depending on the number of devices that need to dissipate heat and the heating power of the devices. The box body 211 serves to store and install. The heat exchange assembly 212 is used for heat exchange when the liquid flows therein. The primary side connection position 2111 and the secondary side connection position 2114 are both used to connect to the corresponding circuit. The first connection position 2121 and the second connection position 2124 are not connected to each other, that is, there is no cross-flow between the liquid flowing in and out of the first connection position 2121 and the liquid flowing in and out of the second connection position 2124.
