In the data center industry, the only key indicator for evaluating energy consumption levels (or energy saving levels to be precise) is PUE, and the calculation formula is: PUE = total load / IT load. However, there are still many differences in the internal system design and structural layout of distributed CDUs, such as not considering the convenience of replenishing / draining coolant in the CDU during maintenance.

[0043] Based on the above application scenarios, an embodiment of the present application provides a cooling distribution unit and a liquid cooling cabinet, which are used to add liquid replenishment / drainage pipelines to improve the maintainability of the cooling distribution unit.

[0049] One possible way to achieve this is as follows: Figure 1 and Figure 2 As shown, the cooling distribution unit is a rectangular plug-in frame structure as a whole. On a plane perpendicular to the thickness direction of the cooling distribution unit, the cooling distribution unit includes a first side A and a second side B that are arranged opposite to each other, that is, Figure 1 and Figure 2The two short sides of the cold distribution unit can be inserted into the liquid cooling cabinet from the second side B when in use. For the convenience of description, the first side A is defined as the front side of the cold distribution unit, and the second side B is defined as the back side of the cold distribution unit. The plate exchange box 1 is arranged on the first side A of the cold distribution unit, that is, the plate exchange box 1 is located on the front side of the cold distribution unit, and the end interfaces of each pipeline are arranged on the second side B of the cold distribution unit, that is, the end interfaces of each pipeline are located on the back side of the cold distribution unit, thereby increasing the space for installing components on the pipeline, and the components are fully equipped and components with high failure rates can be maintained and replaced.

The rear side of the cold distribution unit is provided with a replenishment and drainage port and a drainage port, wherein the replenishment and drainage port is the end interface of the replenishment and drainage pipe 3c, and the drainage port is the end interface of the drainage pipe 3d, so that replenishment / drainage is fast and convenient. When it is necessary to remove the cooling distribution unit from the liquid cooling cabinet, the fluid in the secondary side inlet pipe 3a and the secondary side outlet pipe 3b can be drained respectively to avoid contaminating the liquid cooling cabinet and improve maintainability.

[0051] Reference Figure 1 and Figure 2 The primary outlet pipe 2b is provided with a water valve 2c near the second side B of the cooling distribution unit. The cooling distribution unit also includes a circulation pump 3e provided on the secondary inlet pipe 3a. There are two circulation pumps 3e.

[0070] In a second aspect, an embodiment of the present invention further provides a liquid cooling cabinet, comprising any cooling capacity distribution unit as described in the embodiment of the first aspect.

[0071] The cold distribution unit is installed in the cold plate liquid cooling cabinet to meet the high density and energy saving requirements of the data center. The end interfaces of the secondary side inlet / outlet pipe and the primary side inlet / outlet pipe of the cold distribution unit are connected to the main pipe and cooling pipe of the liquid cooling cabinet through the chuck, and the plug-in terminal 7a is blindly plugged with the bus of the liquid cooling cabinet to obtain electricity. The rear side of the cold distribution unit is provided with a liquid replenishment and drainage port, and the front side is provided with a control panel 8, a power switch 7b, a network port, etc., which realizes the circulation refrigeration of the whole machine while considering the convenience and comfort of human-computer interaction.

[0072] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
