Description

Technical Field

[0001] The utility model relates to the technical field of chilled water distribution units CDU, and particularly to a new type of water chilled water distribution unit CDU for the data center industry. Background Technique

[0002] A data center is a facility that centrally stores computer systems and related components, mainly used for storing, processing, and managing large amounts of data. A data center usually includes servers, storage devices, network devices, and infrastructure that supports the operation of these devices, such as power supply, cooling systems, and security measures.

[0003] Currently, the common chilled water distribution unit CDU usually includes a single-way supply and return main pipe, N end branches, and branch valves. One end of multiple branches is connected to the main pipe. Cut-off valves, thermometers, pressure gauges, and filters are installed on the CDU supply and return main pipes, and the valves often need maintenance and replacement. Since there is only a single-way supply and return water pipe, when the main pipe valves of the CDU for water inlet and outlet need maintenance or replacement, the entire main pipe of the CDU needs to be cut off, resulting in all the terminal air conditioners corresponding to the branch pipes of the CDU being down for a short time. For a data center project, the downtime of the air conditioner will cause the temperature in the computer room to rise rapidly, resulting in the servers crashing due to high temperature, causing irreversible losses, data paralysis or loss, and the losses are immeasurable. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a new type of water chilled water distribution unit CDU for the data center industry, which has the advantages of being convenient for maintaining the valves and preventing all terminal air conditioners from being down for a short time, and solves the problem that when the valves of the existing chilled water distribution unit CDU need maintenance or replacement, the entire main pipe of the CDU needs to be cut off, resulting in all the terminal air conditioners corresponding to the branch pipes of the CDU being down for a short time.

[0005] To achieve the above object, the present utility model provides the following technical solutions: A new type of chilled water distribution unit CDU for the data center industry, including a chilled water main supply pipe, a chilled water main return pipe, a first chilled water distribution unit CDU, and a second chilled water distribution unit CDU.

A supply and return water cut-off assembly is provided on the water supply pipe and the return pipe. Ball valves are fixedly installed on the surfaces of the water supply branch pipe and the return water branch pipe. A supply and return water control assembly is provided on the chilled water main supply pipe and the chilled water main return pipe.

[0006] Further, the supply and return water cut-off assembly includes a first cut-off valve, a second cut-off valve, a third cut-off valve, a fourth cut-off valve, a fifth cut-off valve fixedly installed on the surfaces of the water supply pipe and the return pipe and located inside the first chilled water distribution unit CDU, a sixth cut-off valve, a seventh cut-off valve, an eighth cut-off valve, a ninth cut-off valve, a tenth cut-off valve located inside the second chilled water distribution unit CDU, and an eleventh cut-off valve and a twelfth cut-off valve fixedly installed on the surfaces of the water supply pipe and the return pipe and located between the first chilled water distribution unit CDU and the second chilled water distribution unit CDU.

[0007] Further, the supply and return water control assembly includes a thirteenth cut-off valve, a fourteenth cut-off valve, a fifteenth cut-off valve, a sixteenth cut-off valve all fixedly installed on the surfaces of the chilled water main supply pipe and the chilled water main return pipe. A seventeenth cut-off valve and an eighteenth cut-off valve are fixedly installed on the surfaces of the water supply pipe and the return pipe.

[0008] Further, thermometers, pressure gauges, and filters are fixedly installed on the surfaces of the water supply pipe and the return pipe.

[0009] Further, the number of water supply branch pipes and return water branch pipes in the first chilled water distribution unit CDU and the second chilled water distribution unit CDU is six each.

[0010] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0011] The novel chilled water distribution unit CDU for the data center industry is provided with a dual - path main supply - return water pipe, N + 1 inlet branch pipes and branch ball valves, N + 1 outlet branch pipes and branch ball valves on the chilled water distribution unit CDU. And on the main pipeline inside the CDU, a cut - off valve is installed between each branch pipe. Every two CDUs form a group to jointly serve the row - level air conditioner at the end of the enclosed passage. When the partition valve between the main pipelines inside the CDU needs to be maintained or replaced, the front and rear valves and the branch ball valves are closed, which will affect at most two branch pipelines, that is, two standby air conditioners, without affecting the stable operation of the main air conditioner.

This situation will only cause one corresponding end air-conditioning unit to shut down, and the remaining air-conditioning water can enter from the other main pipeline of the second chilled water distribution unit CDU4. There are two standby air-conditioning units in the enclosed passage. Even if one shuts down, it will not affect the operation of the main air-conditioning units. When the No. 9 cut-off valve in the first chilled water distribution unit CDU1 needs to be maintained or replaced, close the No. 26 cut-off valve, the No. 10 cut-off valve, and the ball valve 21 on the corresponding end air-conditioning branch pipe, and then the No. 9 cut-off valve can be maintained or replaced. This situation will only cause two corresponding end air-conditioning units to shut down, and the remaining air-conditioning water can enter from the other main pipeline of the second chilled water distribution unit CDU4. There are two standby air-conditioning units in the enclosed passage. Even if one shuts down, it will not affect the operation of the main air-conditioning units. The replacement of the remaining valves can be carried out by analogy according to the above steps.
