Description

Technical Field

[0001] The present invention relates to the technical field of liquid cooling systems, and in particular to a maintenance device, a liquid cooling system component and a maintenance method for a liquid cooling system. Background Art

[0002] With the rapid development of communication technology, the power consumption of equipment and chips is increasing, which poses a huge challenge to heat dissipation. Liquid cooling technology has gradually attracted everyone's attention due to its advantages such as strong heat dissipation capacity, energy saving and noise reduction. In order to effectively dissipate the heat of the components to be cooled in the equipment room, the liquid cooling system usually includes a liquid cooling source, a liquid supply pipeline and a liquid return pipeline. The liquid cooling source is used to supply heat exchange medium to the liquid supply pipeline. The heat exchange medium flowing out of the liquid supply pipeline can cool multiple components to be cooled. After that, the heat exchange medium heats up and flows back to the liquid cooling source through the liquid return pipeline. The heat exchange medium is cooled in the liquid cooling source and then flows into the liquid supply pipeline again, thereby forming a liquid cooling cycle. However, when a component or liquid cooling system in the liquid cooling system fails, it is difficult to replace it quickly. Once the failure is costly, the corresponding liquid cooling of the components to be cooled is abnormal, which brings great losses, especially for routers and switches with high equipment reliability requirements. Summary of the invention

[0003] The present invention provides a maintenance device, a liquid cooling system component and a maintenance method for a liquid cooling system, aiming to quickly replace a component to be replaced of a liquid cooling pipeline component of a liquid cooling system.

[0012] The disclosed embodiments provide a maintenance device, a liquid cooling system component, and a maintenance method for a liquid cooling system. When a component in a liquid cooling pipeline component of the liquid cooling system fails or is damaged, the component to be replaced (i.e., the failed pipeline component) can be quickly replaced through the maintenance device, thereby achieving online maintenance of the component to be replaced without shutting down the component to be cooled, reducing the risk of the component to be cooled facing shutdown due to failure, and reducing communication accidents caused by shutdown of the component to be cooled; and improving the user experience, and improving product reliability and competitiveness.

[0031] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments.

In addition, the terms "first" and "second" are used only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present disclosure, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0033] It should also be understood that the terms used in this disclosure are only for the purpose of describing specific embodiments and are not intended to limit the disclosure. As used in this disclosure and the appended claims, the singular forms "a", "an" and "the" are intended to include plural forms unless the context clearly indicates otherwise.

[0034] It should be further understood that the term “and / or” used in this disclosure and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0035] It should also be understood that the methods in the embodiments of the present disclosure are only illustrative and do not necessarily include all the contents and operations / steps, nor must they be performed in the order described. For example, some operations / steps may also be decomposed, combined, or partially merged, so the actual execution order may change according to actual conditions.

[0036] With the continuous innovation and development of Information and Communications Technology (ICT), the power density of communication products has gradually increased. Traditional air-cooled equipment is gradually facing the transition to liquid cooling. However, how to achieve online maintenance of the liquid cooling system without stopping the business has become a key bottleneck restricting the implementation of liquid cooling technology.

[0037] Based on this, the embodiments of the present disclosure provide a maintenance device, a liquid cooling system component, and a maintenance method for a liquid cooling system.

[0038] See also Figure 1The embodiment of the present disclosure provides a liquid cooling system 100, which is used to dissipate heat for a component to be dissipated, so as to dissipate the heat of the component to be dissipated in time, thereby ensuring the normal operation of the component to be dissipated.

[0039] See also Figure 1 In some embodiments, the liquid cooling system 100 includes a liquid cooling source 10 and a heat exchange component 20. The liquid cooling source 10 is used to supply liquid cooling medium, and the heat exchange component 20 is used to heat exchange with the component to be cooled, so as to dissipate the heat at the component to be cooled in time. Exemplarily, the component to be cooled may include at least one of the following: a server, a router, a switch, a heat generating component in a computer room device 300 (see 2), etc.

[0040] It can be understood that the liquid cooling medium flowing out of the liquid cooling source 10 can flow to the heat exchange component 20, and the liquid cooling medium flowing to the heat exchange component 20 can exchange heat with the heat exchange component 20, and the liquid cooling medium flowing through the heat exchange component 20 is heated up to dissipate the heat at the heat exchange component 20, and then dissipate the heat of the component to be dissipated in time; the liquid cooling medium flowing out of the heat exchange component 20 can flow back to the liquid cooling source 10. The liquid cooling medium flowing back to the liquid cooling source 10 is cooled in the liquid cooling source 10, and then flows to the heat exchange component 20 again, thereby forming a liquid cooling cycle.

[0041] Exemplarily, the liquid cooling source 10 includes a cooling dispensing unit (CDU). Exemplarily, the heat exchange component 20 includes a cold plate or a service unit.

[0042] Exemplarily, the liquid cooling medium is in a gaseous state at normal temperature and pressure, and can be converted into a liquid state under a preset pressure condition or a preset temperature condition.

[0043] Exemplarily, the liquid cooling medium includes at least one of the following: hydrofluoroether, perfluorocarbon, and the like.

[0044] See also Figure 1 In some embodiments, the liquid cooling system 100 further includes a liquid cooling pipeline assembly 30 , which is used to connect to the liquid cooling source 10 and the heat exchange component 20 so that the liquid cooling medium can circulate between the liquid cooling source 10 and the heat exchange component 20 .

[0045] See also Figure 1In some embodiments, the liquid cooling pipeline assembly 30 includes a liquid inlet pipeline group 301 and a liquid outlet pipeline group 302. The liquid cooling source 10, the liquid inlet pipeline group 301, the heat exchange component 20, and the liquid outlet pipeline group 302 are connected to form a circulation loop. The liquid cooling medium flowing out of the liquid cooling source 10 flows through the liquid inlet pipeline group 301 and enters the heat exchange component 20. When the liquid cooling medium flows through the heat exchange component 20, it can absorb the heat of the heat exchange component 20, and part of the liquid cooling medium vaporizes. The liquid cooling medium flowing out of the heat exchange component 20 can flow through the liquid outlet pipeline group 302 and return to the liquid cooling source 10.

[0046] Illustratively, the structure of the liquid inlet pipeline assembly 301 and the structure of the liquid outlet pipeline assembly 302 may be the same or different, which is not limited herein.

[0047] See also Figure 1 Exemplarily, the heat exchange component 20 includes a first heat exchange component 21 and a second heat exchange component 22. The liquid inlet pipeline group 301 includes a main delivery pipeline 31, a first liquid distributor 32, a first three-level branch 33, a secondary branch 34, a second liquid distributor 35, and a second three-level branch 36. The liquid cooling source 10 is connected to the first liquid distributor 32 through the main delivery pipeline 31, the first three-level branch 33 and the secondary branch 34 are respectively connected to the first liquid distributor 32, the first liquid distributor 32 is connected to the first heat exchange component 21 through the first three-level branch 33, the first liquid distributor 32 is connected to the second liquid distributor 35 through the secondary branch 34, and the second liquid distributor 35 is connected to the second heat exchange component 22 through the second three-level branch 36. The structures of the liquid inlet pipeline group 301 and the liquid outlet pipeline group 302 are the same or substantially the same.

[0048] In some embodiments, the number of the first heat exchange component 21 and the second heat exchange component 22 can be designed according to actual needs, such as one, two, three, four, five, six, seven, eight, nine or more. The number of the first tertiary branch 33, the secondary branch 34, the second liquid distributor 35 and the second tertiary branch 36 can be set according to actual needs, such as one, two, three or more. Exemplarily, the number of the first tertiary branch 33 of the liquid inlet pipeline group 301 is the same as the number of the first heat exchange component 21, and the number of the second tertiary branch 36 of the liquid inlet pipeline group 301 is the same as the number of the second heat exchange component 22.

[0049] In other embodiments, the secondary branch 34, the second liquid distributor 35, the second tertiary branch 36 and the second heat exchange component 22 may also be omitted, which is not limited here.

[0050] See also Figure 1In some embodiments, the liquid cooling system 100 further includes a quick-release connector 37, which is detachably connected between adjacent pipe components in the liquid cooling pipe assembly 30, or the quick-release connector 37 is detachably connected between the heat exchange component 20 and the liquid cooling pipe assembly 30. Exemplarily, the number of quick-release connectors 37 includes at least two. A quick-release connector 37 is provided between two adjacent pipe components in the liquid cooling pipe assembly 30 to achieve detachable connection between the two adjacent pipe components, so as to facilitate the rapid removal of the component to be replaced and the installation of the replacement component when replacing the component to be replaced, thereby improving maintenance efficiency. Exemplarily, a quick-release connector 37 is provided at the connection between the heat exchange component 20 and the liquid cooling pipe assembly 30 to achieve detachable connection between the heat exchange component 20 and the liquid cooling pipe assembly 30, so as to facilitate the rapid installation and removal of the heat exchange component 20 and the corresponding pipe component when replacing the component to be replaced, thereby providing a guarantee for the rapid replacement of the component to be replaced. For example, a quick-release connector 37 is provided at the connection between the first heat exchange component 21 and the first tertiary branch 33 to achieve a detachable connection between the first heat exchange component 21 and the first tertiary branch 33. For another example, a quick-release connector 37 is provided at the connection between the second heat exchange component 22 and the second tertiary branch 36 to achieve a detachable connection between the second heat exchange component 22 and the second tertiary branch 36.

[0051] See also Figure 2 and Figure 3 In some embodiments, the heat exchange component 20 and at least part of the liquid cooling pipe assembly 30 are used to be arranged in the computer room equipment 300, so as to dissipate heat for the components to be dissipated in the computer room equipment 300. Exemplarily, the heat exchange component 20 and at least part of the liquid cooling pipe assembly 30 may be part of the computer room equipment 300. Exemplarily, the heat exchange component 20 or at least part of the liquid cooling pipe assembly 30 may not be part of the computer room equipment 300, which is not limited here.

[0052] See also Figure 1 and Figure 4 The embodiment of the present disclosure provides a maintenance device 200 for maintaining the liquid cooling system 100 or the liquid cooling pipeline assembly 30 of the liquid cooling system 100 .

[0053] See also Figure 3 and Figure 4In some embodiments, the maintenance device 200 includes a maintenance unit 201 and a pipe storage unit 202. The maintenance unit 201 is used to replace at least part of the liquid cooling system 100 after removing one end of the component to be replaced of the liquid cooling system 100 and before installing the replacement component so that the liquid cooling medium can circulate between the liquid cooling source 10 and the heat exchange component 20 of the liquid cooling system 100; the maintenance unit 201 is at least partially stored in the pipe storage unit 202; when the maintenance unit 201 maintains the component to be replaced, the maintenance unit 201 located at the pipe storage unit 202 can be at least partially released; when the replacement component is installed, the maintenance unit 201 located outside the pipe storage unit 202 can be at least partially stored in the pipe storage unit 202.

[0054] The maintenance device 200 of the above-mentioned embodiment can quickly replace the component to be replaced (i.e., the failed or damaged component of the liquid cooling system 100) when the component of the liquid cooling system 100 fails or is damaged, thereby realizing online maintenance of the component to be replaced without shutting down the component to be cooled, reducing the risk of failure and shutdown of the component to be cooled, and reducing communication accidents caused by shutdown of the component to be cooled; and improving the user experience, product reliability and competitiveness.

[0055] Exemplarily, the components to be replaced include at least one of the following: at least one component of the liquid cooling pipeline assembly 30 of the liquid cooling system 100, the heat exchange component 20, etc. For example, the components to be replaced include at least one of the following: the main delivery pipeline 31, the first liquid distributor 32, the secondary branch 34, and the second liquid distributor 35. For another example, the components to be replaced include at least one of the following: the first tertiary branch 33 and the second tertiary branch 36. For another example, the components to be replaced include the heat exchange component 20.

[0056] See also Figure 5In some embodiments, the pipeline storage unit 202 includes a storage mechanism 2021 and a reset mechanism 2022, and the maintenance unit 201 is at least partially stored in the storage mechanism 2021; the reset mechanism 2022 is connected to the storage mechanism 2021; when the maintenance unit 201 maintains the component to be replaced, the maintenance unit 201 located at the storage mechanism 2021 can be at least partially released; when the replacement component is installed, the maintenance unit 201 located outside the storage mechanism 2021 can be stored in the storage mechanism 2021 under the action of the reset mechanism 2022. It can be understood that when it is necessary to replace the component to be replaced of the liquid cooling system 100, the user or other auxiliary equipment can pull at least part of the maintenance unit 201 outward, so that the maintenance unit 201 located at the storage mechanism 2021 can be at least partially released, so as to better connect with the corresponding component of the liquid cooling system 100 (such as the heat exchange component 20 or the first pipeline, the first pipeline includes the first tertiary branch 33 or the second tertiary branch 36). When the replacement part is installed, the maintenance unit 201 released from the storage mechanism 2021 can be automatically stored in the storage mechanism 2021 under the action of the reset mechanism 2022, which reduces the space occupied by the maintenance unit 201 and the maintenance device 200, is conducive to the miniaturization of the maintenance device 200, and is convenient for the storage and transportation of the maintenance device 200; there is no need for the user to manually store at least part of the maintenance unit 201, freeing the user's hands. It can be understood that the replacement part is a replacement structure of the part to be replaced. For example, when the part to be replaced includes the first liquid dispenser 32, the replacement part is a new first liquid dispenser 32.

[0057] Exemplarily, the reset mechanism 2022 includes an elastic member, such as a spring or a torsion spring, etc. In other embodiments, the reset mechanism 2022 may also be omitted.

Exemplarily, the first movement direction is opposite to the second movement direction. Exemplarily, at least part of the maintenance unit 201 includes at least one of the following: a maintenance main pipeline 2011, a first maintenance pipeline 2013, and a second maintenance pipeline 2014.

[0059] In some embodiments, at least a portion of the maintenance unit 201 can be wound around the storage mechanism 2021; the storage mechanism 2021 can rotate to release or store at least a portion of the maintenance unit 201. In this way, the storage mechanism 2021 can store or release at least a portion of the maintenance unit 201 in an orderly manner, which is beneficial to further reduce the space occupied by the maintenance unit 201 and the maintenance device 200.

[0060] See also Figure 6 and Figure 7 In some embodiments, the storage mechanism 2021 includes a winding member 20211 and a shell cover 20212. The maintenance unit 201 can be at least partially wound on the winding member 20211. The winding member 20211 can rotate to release or store at least part of the maintenance unit 201. The shell cover 20212 is used to cover the winding member 20211 and the maintenance unit 201 stored at the winding member 20211, thereby protecting the maintenance unit 201 wound at the winding member 20211 to a certain extent, playing a role of dust or liquid proof, and making the maintenance device 200 more beautiful.

[0061] See also Figure 6 and Figure 8 In some embodiments, the maintenance unit 201 includes a maintenance main line 2011 and a maintenance liquid distributor 2012. The maintenance main line 2011 is used to communicate with the liquid cooling source 10; the maintenance liquid distributor 2012 can be connected to the maintenance main line 2011, and the maintenance main line 2011 is correspondingly provided with a pipeline storage unit 202 to reduce the storage volume of the maintenance unit 201 and the maintenance device 200.

[0062] See also Figure 6 and Figure 8 In some embodiments, the maintenance unit 201 includes a maintenance main line 2011, a maintenance liquid distributor 2012, and a first maintenance line 2013.

For example, one of the first maintenance line 2013 and the maintenance main line 2011 is correspondingly provided with a line storage unit 202. For another example, the first maintenance line 2013 and the maintenance main line 2011 are respectively correspondingly provided with a line storage unit 202 to reduce the storage volume of the maintenance unit 201 and the maintenance device 200 as much as possible.

[0063] See also Figure 6 and Figure 8In some embodiments, the main maintenance line 2011 and the first maintenance line 2013 are arranged on the same side of the maintenance dispenser 2012, so as to reasonably arrange the positions of the main maintenance line 2011 and the first maintenance line 2013 and reasonably utilize the space around the maintenance dispenser 2012, so that the maintenance device 200 has a compact structure and occupies a small space.

[0064] In some embodiments, the first maintenance pipeline 2013 and the maintenance main pipeline 2011 are respectively provided with pipeline storage units 202, and the pipeline storage units 202 corresponding to the first maintenance pipeline 2013 and the pipeline storage units 202 corresponding to the maintenance main pipeline 2011 are arranged along the first direction. The structural layout of the maintenance device 200 is reasonable, the structure is compact, and the space occupied is small.

[0065] For example, the first direction is Figure 6 As shown in the Y direction.

[0066] Exemplarily, the first direction is the up-down direction of the maintenance device 200 .

[0067] See also Figure 6 In some embodiments, the maintenance unit 201 further includes a second maintenance pipeline 2014, the second maintenance pipeline 2014 is connected to the maintenance dispenser 2012, and at least one of the first maintenance pipeline 2013, the second maintenance pipeline 2014 and the maintenance main pipeline 2011 is provided with a pipeline storage unit 202 to reduce the storage volume of the maintenance unit 201 and the maintenance device 200. For example, one of the first maintenance pipeline 2013, the second maintenance pipeline 2014 and the maintenance main pipeline 2011 is provided with a pipeline storage unit 202. For another example, any two of the first maintenance pipeline 2013, the second maintenance pipeline 2014 and the maintenance main pipeline 2011 are provided with a pipeline storage unit 202 respectively. For another example, the first maintenance pipeline 2013, the second maintenance pipeline 2014 and the maintenance main pipeline 2011 are provided with a pipeline storage unit 202 respectively to reduce the storage volume of the maintenance unit 201 and the maintenance device 200 as much as possible. It can be understood that the structures of the pipeline storage units 202 corresponding to the first maintenance pipeline 2013, the second maintenance pipeline 2014 and the maintenance main pipeline 2011 can be the same or different, and there is no limitation here.

[0068] See also Figure 6 and Figure 8 In some embodiments, the first maintenance pipeline 2013 and the second maintenance pipeline 2014 are respectively arranged on opposite sides of the maintenance dispenser 2012 to fully utilize the space around the maintenance dispenser 2012, so that the structure of the maintenance device 200 is more compact and the maintenance device 200 occupies less space.

[0069] Exemplarily, when the liquid cooling system 100 is maintained, the first maintenance pipeline 2013 is used to connect to the first tertiary branch 33 or the first heat exchange component 21, and the second maintenance pipeline 2014 is used to connect to the second tertiary branch 36 or the second heat exchange component 22. Exemplarily, when the liquid cooling system 100 is maintained, the first maintenance pipeline 2013 is used to connect to the second tertiary branch 36 or the second heat exchange component 22, and the second maintenance pipeline 2014 is used to connect to the first tertiary branch 33 or the first heat exchange component 21.

[0070] Exemplarily, when maintaining a component to be replaced (such as the first liquid distributor 32 or other piping components of the liquid cooling system 100), one of the first maintenance pipeline 2013 and the second maintenance pipeline 2014 can be used to connect to the first heat exchange component 21 or the first tertiary branch 33 of the liquid cooling system 100 according to actual needs, and the other of the first maintenance pipeline 2013 and the second maintenance pipeline 2014 can be used to connect to the second heat exchange component 22 or the second tertiary branch 36 of the liquid cooling system 100.

[0071] Exemplarily, the maintenance main line 2011 includes a maintenance liquid inlet main line (not marked) and a maintenance liquid outlet main line (not marked). When the maintenance main line 2011 is needed to maintain the liquid cooling system 100, the maintenance liquid inlet main line and the maintenance liquid outlet main line can be released from the storage mechanism 2021 synchronously or asynchronously; when the maintenance of the liquid cooling system 100 is completed, at least part of the maintenance liquid inlet main line and at least part of the maintenance liquid outlet main line can be synchronously or asynchronously stored in the storage mechanism 2021. The maintenance liquid inlet main line and the maintenance liquid outlet main line can share a storage mechanism 2021, or the maintenance liquid inlet main line and the maintenance liquid outlet main line can each be provided with a separate storage mechanism 2021.
