[0038] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0039] Reference below Figure 1-Figure 7 A CDU unit according to an embodiment of the present application is described.

[0040] like Figure 1 As shown, the CDU unit includes: a cabinet 100, a pipeline assembly 200, an electric control module 300 and a functional module 400.

[0041] like Figure 2 and Figure 3 As shown, the cabinet 100 includes a first opening 110 and a second opening 120 that are oppositely disposed. An accommodating cavity 130 is formed inside the cabinet 100 , and the accommodating cavity 130 is located between the first opening 110 and the second opening 120 .

[0042] The pipe assembly 200 is disposed near the first opening 110 and is fixedly installed in the accommodating cavity 130 .

[0043] The pipeline assembly 200 includes a primary pipeline and a secondary pipeline. The cooling medium in the primary pipeline and the secondary pipeline flows through the heat exchanger for heat exchange.

[0044] For example, after the cooling medium in the secondary side pipeline is cooled through heat exchange with the cooling medium in the primary side pipeline, it can flow to a data center, a server room, or other external equipment that requires efficient cooling to cool the external equipment.

[0045] It should be noted that due to the differences in external equipment, the primary side pipeline or the secondary side pipeline of the pipeline assembly 200 may need to be expanded. The pipeline assembly 200 is set close to the first opening 110 of the cabinet 100, which can facilitate operation and maintenance personnel to expand the pipeline.

[0046] In actual implementation, temperature sensors, pressure sensors, electric two-way valves, filters and other devices can be installed on the primary side pipeline or the secondary side pipeline of the pipeline assembly 200. The pipeline assembly 200 is set close to the first opening 110 of the cabinet 100, which can also facilitate operation and maintenance personnel to perform daily inspection and maintenance of the devices installed on the pipeline of the pipeline assembly 200.

[0047] The electric control module 300 is disposed near the second opening 120 and is rotatably installed in the accommodating cavity 130 .

[0048] The electric control module 300 may include an electric control box 310 and electric components disposed inside the electric control box 310. The electric components are used to electrically connect to some functional modules 400 described below to control the start and stop of the pipeline assembly 200 and adjust the flow of the cooling medium.

[0049] For example, the electronic control module 300 may be an electronic control device such as a controller, a relay, or a switch that requires frequent maintenance, operation, and observation.

[0050] The functional module 400 is disposed in the accommodating cavity 130. The functional module 400 may be a device that provides functions such as extracting cooling medium, heat exchange, and voltage stabilization.

[0051] For example, the functional module 400 may be a control valve and a water pump, etc. The control valve and the water pump may be installed on the primary side pipeline or the secondary side pipeline of the pipeline assembly 200 and electrically connected to the controller of the electronic control module 300 .

[0052] A certain amount of space is reserved next to the water pump to facilitate the overall heat exchange capacity of the CDU unit. As previously mentioned, the electronic control module 300 can be rotated toward the second opening 120 and removed from the second opening 120. After the electronic control module 300 is removed from the accommodating cavity 130, the space between the electronic control module 300 and the second opening 120 is cleared, making the electronic control module 300 accessible from the second opening 120. This facilitates maintenance and inspection of the functional module 400 by maintenance personnel.

[0053] In this embodiment, the areas near the first opening 110 and the second opening 120 in the accommodating cavity 130 are used to accommodate the pipeline assembly 200 and the electric control module 300 that require frequent maintenance, operation, and observation, respectively. The area in the accommodating cavity 130 and between the pipeline assembly 200 and the electric control module 300 is used to accommodate the functional module 400. After the electric control module 300 is rotated out of the first opening 110 of the cabinet 100, the functional module 400 can be maintained. In this way, the layout of the modules in the standardized layout CDU unit can not only reduce the learning cost of the operation and maintenance personnel, but also improve the convenience of operation and maintenance for the operation and maintenance personnel.

[0054] like Figure 2-Figure 4 As shown, in actual implementation, the CDU unit further includes: a first cabinet door 111 and a second cabinet door 121.

[0055] The first cabinet door 111 is provided at the first opening 110 for opening and closing the first opening 110 ; the second cabinet door 121 is provided at the second opening 120 for opening and closing the second opening 120 .

[0056] The electric control module 300 can rotate and be removed from the second opening 120. In specific implementation, it can have the following two structural forms:

[0057] First, as Figure 3 and Figure 4 As shown, the electric control module 300 includes an electric control box 310 and electric components disposed inside the electric control box 310 . A rotating structure 311 is installed outside the electric control box 310 , and the electric control box 310 is mounted on the wall of the accommodating cavity 130 through the rotating structure 311 .

[0058] The rotating structure 311 may be a hinge, and the electric control box 310 is mounted on the wall of the accommodating cavity 130 via the hinge, and can be in the first position ( Figure 3 ) and the second position ( Figure 4 positions shown).

[0059] Secondly, the electric control module 300 includes an electric control box 310 and electric components disposed inside the electric control box 310 . The electric control box 310 is fixedly mounted on the inner wall of the second cabinet door 121 , and the electric control box 310 rotates along with the second cabinet door 121 between the first position and the second position.

[0060] In the above two structural forms, when the electric control box 310 is in the first position, as shown in FIG. Figure 3 As shown in FIG, the electric control box 310 is close to the second opening 120 and is located in the accommodating cavity 130; when the electric control box 310 is in the second position, as shown in FIG. Figure 4 As shown in FIG, the electric control box 310 is close to the second opening 120 and outside the accommodating cavity 130 .

[0061] like Figure 1 and Figure 6 As shown, in some embodiments, the functional modules 400 are arranged in descending order along the height direction in the accommodating cavity 130 according to the maintenance frequency, and the heat exchanger is arranged in the upper part of the accommodating cavity 130 .

[0062] The functional module 400 includes a first functional module 410 , a second functional module 420 and a third functional module 430 .

[0063] Exemplarily, the first functional module 410 may be a heat exchanger.

[0064] The first function module 410 , the second function module 420 and the third function module 430 are arranged in sequence from top to bottom according to the maintenance frequency, which can further improve the convenience of operation and maintenance for operation and maintenance personnel.

[0065] Exemplarily, the second functional module 420 may be a water tank and / or an expansion tank.

[0066] The cooling medium in the secondary side pipeline of the pipeline assembly 200 flows through the water tank and / or the expansion tank. The second functional module 420 is closer to the second opening 120 than the third functional module 430, which can improve the convenience of maintenance for operation and maintenance personnel.

[0067] For example, the third functional module 430 may be a water pump.

[0068] The cooling medium in the secondary side pipeline of the pipeline assembly 200 flows through the water pump.

[0069] It should be noted that the primary side pipeline of the pipeline assembly 200 can be connected to a chiller, a dry cooler or a cooling tower, and serve as a cold source for the secondary side pipeline of the pipeline assembly 200 .

[0070] After the cooling medium in the primary side pipeline and the secondary side pipeline flows through the heat exchanger for heat exchange, the secondary side pipeline is connected to the external equipment that needs to be cooled, providing circulation power and providing cooling medium for the external equipment.

[0071] like Figure 5 As shown, the inlet 210 and the outlet 240 of the primary side pipeline are respectively connected to the outside from the bottom of the cabinet 100; the inlet 230 and the outlet 220 of the secondary side pipeline are connected to the outside from the bottom of the cabinet 100.

[0072] In this embodiment, the inlet 210 of the primary side pipeline, the outlet 220 of the secondary side pipeline, the inlet 230 of the secondary side pipeline and the outlet 240 of the primary side pipeline are all arranged at the bottom of the cabinet 100, which can better realize the parallel connection between cabinets 100 of different numbers.

[0073] In a specific implementation, the number of cabinets 100 can be multiple and arranged side by side, wherein: the first openings of multiple cabinets 100 are arranged side by side, the second openings of multiple cabinets 100 are arranged side by side, the side walls between the first openings 110 and the second openings 120 of adjacent cabinets 100 are abutted, and the primary side pipelines of adjacent cabinets 100 are interconnected (the pipelines are arranged in parallel or in series), and the secondary side pipelines of adjacent cabinets 100 are interconnected (the pipelines are arranged in parallel or in series).

[0074] Figure 6 1 is a schematic structural diagram of a CDU unit with the side door panel of the cabinet 100 removed, wherein the side door panel of the cabinet 100 is adjacent to the first opening 110 and the second opening 120 of the cabinet 100 .

[0075] like Figure 6 and Figure 7 As shown, in some embodiments, the heat exchanger is a plate heat exchanger, which is disposed close to the pipeline assembly 200 and defines an expansion space 140 between the plate heat exchanger and the electronic control module 300 .

[0076] In this embodiment, when the electronic control module 300 is rotated out from the second opening 120, the operation and maintenance personnel can increase the number of plates in each heat exchange unit 411 of the plate heat exchanger at the expansion space 140, thereby improving the ability of the plate heat exchanger to achieve heat exchange between the secondary side pipeline and the primary side pipeline.

[0077] In actual implementation, the pipeline assembly 200 is provided with an electric control valve for controlling the water flow in the plate heat exchanger. The electric control valve is set close to the plate heat exchanger. The electric control valve has a certain risk of damage and requires maintenance and inspection by operation and maintenance personnel.
