[0002] In scenarios like data centers, heat dissipation cooling devices, such as liquid cooling, are often required to efficiently cool electronic equipment within the data center. Currently, cold plate liquid cooling systems are typically used to tightly attach a heat dissipation cold plate to the CPU or other heat-generating components. Coolant (typically pure water) continuously flows through the cold plate, removing the primary heat. Existing cold plate liquid cooling systems, such as other liquid cooling systems, typically directly deliver the cooling medium (e.g., pure water) to the target electronic equipment. These systems lack or have only minimal maintenance capabilities, and cannot effectively monitor and maintain the effective flow of the cooling medium without interrupting the flow of the cooling medium.

DETAILED DESCRIPTION

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0031] like Figure 1-Figure 5 As shown, an integrated liquid cooling structure that is easy to detect and maintain, the integrated liquid cooling structure can be used on a cabinet to cool the target electronic equipment installed on the cabinet, the cabinet includes a cabinet body 3, a connecting pipe 1 and a collecting and distributing liquid pipe 2, the integrated liquid cooling structure is installed on the cabinet body 3, and is connected to the collecting and distributing liquid pipe 2, the collecting and distributing liquid pipe 2 is connected to several connecting pipes 1, and each connecting pipe 1 is connected to a corresponding target electronic device to transport liquid cooling medium to the target electronic device or to recover the liquid cooling medium after cooling from the target electronic device through the connecting pipe 1 to the collecting and distributing liquid pipe 2 again, and the collecting and distributing liquid pipe 2 then transports the liquid cooling medium to the integrated liquid cooling structure.

[0032] The integrated liquid cooling structure includes a liquid return pipe 4, a liquid outlet pipe 7, a water inlet pipe 6, a water outlet pipe 5, a circulation pump 30, an intermediate heat exchanger 20, a primary side maintenance ring network 18, and a secondary side maintenance ring network 8. One end of the water inlet pipe 6 is used to communicate with a cooling medium source so that external cooling medium can be transported from the water inlet pipe 6 to the integrated liquid cooling structure to provide liquid cooling medium. The other end of the water inlet pipe 6 is connected to the primary side maintenance ring network 18, which is an annular structure with a through cavity. The primary side maintenance ring network 18 is connected to one end of a fifth connecting pipe 24, the other end of which is connected to one end of a circulating liquid outlet pipe 19, and the other end of the circulating liquid outlet pipe 19 is connected to the intermediate heat exchanger 20.

[0033] The primary maintenance ring network 18 includes a fifth connecting pipe 181, a sixth connecting pipe 182, a seventh connecting pipe 184, and an eighth connecting pipe 185, which are connected end-to-end. These five connecting pipes 181, 182, 184, and 185 form a rectangular ring structure. The fifth connecting pipe 181 is located near the water inlet pipe 6, and the sixth connecting pipe 182 is located near the intermediate heat exchanger 20 and is spaced parallel to the intermediate heat exchanger 20.

[0034] A valve for opening and closing fifth connecting tube 181 is installed on fifth connecting tube 181. A fourth valve 183 for opening and closing sixth connecting tube 182 is installed on sixth connecting tube 182. A second filter (not shown) for filtering impurities from the liquid cooling medium is also installed on sixth connecting tube 182. An ultra-dense filter can be used as the second filter. A valve for opening and closing eighth connecting tube 185 is also installed on eighth connecting tube 185.

[0035] One end of the circulating liquid outlet pipe 19 connected to the fifth connecting pipe 24 is also connected to one end of the fourth bend pipe 22, and the other end of the fourth bend pipe 22 is connected to one end of the water outlet pipe 5, and the fourth bend pipe 22 spans from the inner side of the fifth connecting short pipe 181 across the seventh connecting short pipe 184 and is located on the outer side of the seventh connecting short pipe 184.

[0036] One end of the outlet pipe 5, connected to the fourth curved pipe 22, is also connected to the intermediate heat exchanger 20. The other end of the outlet pipe 5 is used to discharge the cooled liquid cooling medium to the outside. A second control box (not shown) is connected to the junction between the outlet pipe 5 and the fourth curved pipe 22. This second control box is used to switch whether the liquid cooling medium discharged from the intermediate heat exchanger 20 through one end of the outlet pipe 5 flows into the fourth curved pipe 22 or is discharged directly from the other end of the outlet pipe 5. The second control box acts as a solenoid three-way valve, opening and closing a specific pipe, allowing the liquid cooling medium to flow out of the fourth curved pipe 22 or directly out of the other end of the outlet pipe 5.

[0037] The output liquid cooling pipe 17 connected to the intermediate heat exchanger 20 is connected to one end of the third connecting pipe 13 and one end of the second curved pipe 14. The second curved pipe 14 is also equipped with a first control box 15 for opening and closing the second curved pipe 14. The other end of the third connecting pipe 13 is connected to the liquid outlet pipe 7, which is connected to one of the manifolds 2 installed on the cabinet 3. The other end of the second curved pipe 14 is connected to the first curved pipe 11. The other end of the first curved pipe 11 is connected to one end of the first connecting pipe 9 and one end of the liquid return pipe 4. The other end of the liquid return pipe 4 is connected to another manifold 2 installed on the cabinet 3. The liquid return pipe 4 is equipped with a first valve 10 for opening and closing the liquid return pipe 4.

[0038] The output liquid cooling pipe 17 is also provided with a second valve 16 for opening and closing the output liquid cooling pipe 17 .

[0039] The other end of the first connecting pipe 9 is connected to the secondary side maintenance ring network 8, which is located above the primary side maintenance ring network 18, so that the secondary side maintenance ring network 8 and the primary side maintenance ring network 18 form a layered structure to save installation space, which is particularly suitable for installation in a small space such as a cabinet. The secondary side maintenance ring network 8 includes a first connecting short pipe 81, a second connecting short pipe 82, a third connecting short pipe 83 and a fourth connecting short pipe 85 connected end to end. The first connecting short pipe 81, the second connecting short pipe 82, the third connecting short pipe 83 and the fourth connecting short pipe 85 form a rectangular ring structure. Among them, the first connecting short pipe 81 is equipped with a fifth valve 87 for opening and closing the first connecting short pipe 81, the third connecting short pipe 83 is equipped with a third valve 84 for opening and closing the third connecting short pipe 83, and the fourth connecting short pipe 85 is equipped with a first filter 86 for filtering impurities in the fourth connecting short pipe 85. The first filter 86 can be an ultra-dense filter.

[0040] The third connecting short pipe 83 is also connected to one end of the second connecting pipe 12, the other end of which is connected to the circulation pump 30. The circulation pump 30 is also connected to one end of the third curved pipe 21, the other end of which is connected to one end of the fourth connecting pipe 23, the other end of which is connected to the intermediate heat exchanger 20. A valve (not shown) is also installed on the fourth connecting pipe 23 for opening and closing the fourth connecting pipe 23.

[0041] In an optional embodiment, a pressure relief valve is further installed on the third connecting pipe 13 for pressure relief, that is, the liquid cooling medium or the liquid cooling medium mixed with gas in the third connecting pipe 13 is discharged to adjust the pressure in the third connecting pipe 13 .

[0042] In actual use, liquid cooling medium is first injected into the primary-side maintenance ring network 18 through the water inlet pipe 6. The liquid cooling medium flows from the water inlet pipe 6 into the fifth connecting short pipe 181, the sixth connecting short pipe 182, the seventh connecting short pipe 184, and the eighth connecting short pipe 185 in sequence. Then, the liquid cooling medium flows to the fifth connecting pipe 24 and flows into the intermediate heat exchanger 20 through the circulating liquid outlet pipe 19. Since the end of the fourth elbow 22 connected to the fifth connecting pipe 24 is vertically mounted on the upper end of the fifth connecting pipe 24, under the action of gravity, the liquid cooling medium does not flow directly into the fourth elbow 22 or flow to other places through the fourth elbow 22.

[0043] Next, the liquid cooling medium flows out of the intermediate heat exchanger 20 and into the output liquid cooling pipe 17. The liquid cooling medium flowing out of the output liquid cooling pipe 17 then flows through the third connecting pipe 13 and into the liquid outlet pipe 7. After flowing out of the liquid outlet pipe 7, it flows through a manifold 2 on the cabinet 3 and into different connecting pipes 1. From there, it flows into different target electronic devices, cooling the target electronic devices. After cooling the target electronic devices, the liquid cooling medium flows out of the target electronic devices again through another connecting pipe 1 and into another manifold 2. All the liquid cooling medium that has undergone cooling and cooling is collected from different connecting pipes 1 into a manifold 2 before flowing into the return pipe 4. After flowing out of the return pipe 4, the liquid cooling medium passes through the first connecting pipe 9 and flows into the secondary maintenance ring network 8. It then passes through the second connecting pipe 82, the first connecting pipe 81, the fourth connecting pipe 85, and the third connecting pipe 83 within the secondary maintenance ring network 8. From the third connecting pipe 83, it flows into the second connecting pipe 12, and then into the circulation pump 30. Under the action of the circulation pump 30, the liquid cooling medium flows through the third elbow 21 and into the fourth connecting pipe 23. From the fourth connecting pipe 23, it flows into the intermediate heat exchanger 20, and then flows out of the intermediate heat exchanger 20 to the outlet pipe 5. The liquid cooling medium flowing out of the return pipe 4 is discharged directly from the outlet pipe 5 or flows into the fourth elbow 22. After passing through the fourth elbow 22, the liquid cooling medium flows into the circulation outlet pipe 19, and then flows into the intermediate heat exchanger 20 again, thus achieving the recycling of the liquid cooling medium.

[0044] The second control box can control the liquid cooling medium to be discharged from the liquid return pipe 4 or to flow into the fourth curved pipe 22 , which is equivalent to the second control box being a three-way solenoid valve that can determine the flow direction of the liquid cooling medium.

[0045] When it is necessary to inspect and repair the pipeline through which the liquid-cooling medium that has been discharged after the cooling process flows, it is only necessary to perform inspection and maintenance on the secondary side maintenance ring network 8. For example, by opening or closing the corresponding valves on the different connecting short pipes on the secondary side maintenance ring network 8, it is determined whether the liquid-cooling medium can flow through normally. If it can flow through after opening and cannot flow through after closing, it indicates that the current pipeline is normal and can meet the normal flow of the liquid-cooling medium. Correspondingly, if it is necessary to repair and replace a certain connecting short pipe, the corresponding valve can be closed to achieve the repair and replacement of the currently faulty connecting short pipe. Similarly, when it is necessary to inspect and repair whether the pipeline through which the liquid-cooling medium that is introduced by the water inlet pipe 6 flows is normal, it can be determined whether the liquid-cooling medium can flow through normally by opening or closing the corresponding valves on the different connecting short pipes on the primary side maintenance ring network 18. If it can flow through after opening and cannot flow through after closing, it indicates that the current pipeline is normal and can meet the normal flow of the liquid-cooling medium.

[0046] In some cases, if the liquid cooling medium does not need to flow through the target electronic device, that is, if cooling is not required, the first control box 15 and the circulation pump 30 are turned on, and the liquid cooling medium flowing out of the intermediate heat exchanger 20 flows out of the output liquid cooling pipe 17 and directly into the second elbow 14, without flowing into the third connecting pipe 13. After passing through the second elbow 14, the liquid cooling medium flows into the first connecting pipe 9, and then through the secondary side maintenance ring network 8, flows into the second connecting pipe 12, and then flows through the second connecting pipe 12 into the circulation pump 30, and then flows into the intermediate heat exchanger 20 and is finally discharged directly through the outlet pipe 5.

[0047] The present invention can well realize the recycling of liquid cooling medium to achieve more efficient cooling and temperature reduction treatment of target electronic equipment. At the same time, it can also determine the flow direction of the liquid cooling medium as needed, and detect and repair whether the flow is normal during the flow of the liquid cooling medium and replace a certain pipeline. The use of two layered maintenance ring networks can not only save installation space, but also realize the flow detection of the liquid cooling medium before cooling and temperature reduction treatment and the flow detection of the liquid cooling medium after cooling and temperature reduction treatment, and the detection efficiency is higher.

[0048] The embodiment disclosed in this specification is merely an illustration of one aspect of the present invention. The scope of protection of the present invention is not limited to this embodiment. Any other functionally equivalent embodiments fall within the scope of protection of the present invention. Those skilled in the art can make various other corresponding changes and modifications based on the technical solutions and concepts described above, and all such changes and modifications should fall within the scope of protection of the claims of the present invention.
