Abstract
Description
Technical Field
[0001] This application relates to the field of server liquid cooling technology, specifically to a liquid-cooled cabinet and liquid cooling system. Background Technology
[0002] Immersion liquid cooling technology has become the preferred cooling method for many data centers due to its significant advantages such as efficient heat dissipation, space saving, reduced energy consumption, and enhanced hardware durability. To meet different needs, immersion liquid cooling can use either fluorinated liquid coolants or oil-based coolants as the cooling medium. Compared to fluorinated liquids, oil-based coolants are more environmentally friendly and have a cost advantage; therefore, oil-based coolants are widely used in immersion liquid cooling technology.
[0003] During the cooling process, the server needs to be immersed in coolant. When using oil-based coolant as the cooling medium, if the server malfunctions and requires maintenance, it needs to be removed from the liquid-cooled cabinet and transferred to a designated cleaning room for cleaning before it can be inspected and maintained.
[0004] During server relocation, coolant dripping is inevitable, leading to environmental contamination and complicating data center cleaning efforts. Utility Model Content
[0005] In view of the above problems, this application provides a liquid-cooled cabinet and liquid cooling system that can clean the server without polluting the environment.
[0006] According to one aspect of the embodiments of this application, a liquid-cooled cabinet is provided, comprising: a cabinet body with an opening at the top, and an internally disposed liquid-cooling chamber and a cleaning chamber separated from each other. The liquid-cooling chamber is used to hold coolant and accommodate servers for immersion liquid cooling of the servers, and the cleaning chamber is used to accommodate servers to be cleaned; a cover plate covering the opening; and a cleaning device including a main pipeline, multiple branch pipelines, and multiple nozzles. The main pipeline is disposed within the cleaning chamber, and each branch pipeline is connected to the main pipeline. The multiple branch pipelines are disposed on at least two opposite sides within the cleaning chamber and extend vertically. Multiple nozzles are arranged vertically on each branch pipeline. A drive pump is disposed on the main pipeline, and the drive pump is used to pump cleaning fluid from the main pipeline into the multiple branch pipelines and spray it onto the servers to be cleaned through the nozzles to clean the servers.
[0007] In one alternative configuration, the nozzle is tilted downwards.
[0008] In one alternative embodiment, the cleaning device further includes a storage tank located at the bottom of the cleaning chamber for storing cleaning fluid; a main pipeline is connected to the storage tank so that a drive pump can pump the cleaning fluid from the storage tank into multiple branch pipelines.
[0009] In one alternative embodiment, the cleaning device further includes a return line located at the bottom of the cleaning chamber and connected to a storage tank. The return line is used to allow the cleaning fluid that is sprayed from the nozzle and eventually falls to the bottom of the cleaning chamber to flow back into the storage tank.
[0010] In one alternative embodiment, a partition is provided inside the cleaning chamber, which vertically divides the cleaning chamber into a first chamber and a second chamber, with the first chamber located above the second chamber. The first chamber is used to accommodate the server to be cleaned, while the storage tank and main pipeline are both located in the second chamber. A branch pipeline is connected to the main pipeline in the second chamber, and the branch pipeline passes through the partition in a sealed manner and extends into the first chamber. A nozzle is located on the portion of the branch pipeline located in the first chamber. A return port is provided on the partition, and a return pipeline is located in the second chamber, with both ends of the return pipeline connected to the return port and the storage tank, respectively.
[0011] In one alternative embodiment, a controller is also provided inside the second cavity, and an operation panel is provided on the cabinet. The controller is electrically connected to both the operation panel and the drive pump.
[0012] In one alternative embodiment, the cover plate includes a first cover plate and a second cover plate. The first cover plate covers the portion of the opening corresponding to the liquid cooling chamber, and the second cover plate covers the portion of the opening corresponding to the cleaning chamber. The first cover plate and the second cover plate can be opened or closed relatively independently. A sensor is installed on the cabinet at a position corresponding to the second cover plate. The sensor is electrically connected to a controller. The controller is used to detect the opening and closing status of the second cover plate through the sensor and control the operation of the drive pump according to the opening and closing status of the second cover plate.
[0013] In one alternative, the liquid-cooled cabinet also includes multiple drying units located on at least two sides within the cleaning chamber, which are used to dry the servers after cleaning has been completed.
[0014] In one alternative configuration, the cabinet contains a liquid-cooled inner liner and a cleaning inner liner. The liquid-cooled inner liner forms a liquid-cooling cavity, and the cleaning inner liner forms a cleaning cavity. The height of the liquid-cooled inner liner is lower than that of the cleaning inner liner.
[0015] According to another aspect of the embodiments of this application, a liquid cooling system is provided, including the liquid cooling cabinet as described in any of the above.
[0016] The liquid-cooled cabinet provided in this embodiment has a liquid-cooling chamber and a cleaning chamber separated from each other inside the cabinet. The liquid-cooling chamber is responsible for cooling during server operation. Servers requiring cleaning in the liquid-cooling chamber can be directly transferred to the cleaning chamber for cleaning between maintenance sessions, without needing to be transferred to a cleaning room or other equipment for cleaning. This effectively avoids the environmental contamination caused by coolant dripping from the servers requiring cleaning. In addition, the cleaning device in the cleaning chamber has multiple branch pipes arranged opposite each other on at least two sides. The multiple branch pipes extend vertically, and each branch pipe has multiple nozzles arranged vertically to ensure that the cleaning fluid sprayed by the nozzles can fully cover the servers requiring cleaning, thereby ensuring the cleaning effect of the servers requiring cleaning and providing a guarantee for subsequent server operation and maintenance.

For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.
[0036] To avoid contaminating the data center environment due to coolant dripping during the transfer of servers between cleaning rooms, this application proposes integrating a cleaning device into the liquid-cooled rack. This allows the liquid-cooled rack itself to clean the servers requiring maintenance without needing to be transferred to a cleaning room, thus preventing coolant dripping and environmental pollution.
[0037] Based on this, according to one aspect of the embodiments of this application, a liquid-cooled cabinet is provided; please refer to the following for details. Figure 1 The figure shows a perspective view of a liquid-cooled server rack 100, which includes a rack body 110 and a cover plate 120. The top of the rack body 110 has an opening 111, which is covered by the cover plate 120. The interior of the rack body 110 contains a liquid-cooling chamber 112 and a cleaning chamber 113, which are separated from each other. The liquid-cooling chamber 112 is used to hold the coolant and house the servers for immersion liquid cooling, while the cleaning chamber 113 is used to house servers that need cleaning.
[0038] When the server in the liquid cooling chamber 112 malfunctions or other abnormalities and requires maintenance, first open the cover 120, and then the server (i.e. the server that needs to be cleaned) can be lifted and transferred to the cleaning chamber 113 by maintenance equipment or other means.
[0039] Specifically, such as Figure 1As shown, a liquid-cooled inner liner 1141 and a cleaning inner liner 1142 can be installed inside the cabinet 110. The liquid-cooled inner liner 1141 forms a liquid-cooled cavity 112 inside, and the cleaning inner liner 1142 forms a cleaning cavity 113 inside. The individual cabinet 110, liquid-cooled inner liner 1141 and cleaning inner liner 1142 are all conventional shell-shaped structures, which are convenient for manufacturing and assembly.
[0040] The height of the liquid-cooled inner tank 1141 can be lower than that of the cleaning inner tank 1142. Correspondingly, the liquid level of the coolant in the liquid-cooled cavity 112 of the liquid-cooled inner tank 1141 is lower than the opening at the top of the cleaning inner tank 1142. This is designed to prevent the coolant from flowing into the cleaning cavity 113 on the cleaning inner tank 1142 and affecting subsequent cleaning work when the coolant level fluctuates due to the insertion or removal of the server into the liquid-cooled inner tank 1141.
[0041] Please combine further Figure 2 The diagram shows an internal perspective view of the cleaning chamber 113. The liquid-cooled cabinet 100 also includes a cleaning device 130, which comprises a main pipe 131, multiple branch pipes 132, and multiple nozzles 133. The main pipe 131 is disposed within the cleaning chamber 113, and each branch pipe 132 is connected to the main pipe 131. The multiple branch pipes 132 are disposed on at least two opposite sides of the cleaning chamber 113 and extend vertically. Multiple nozzles 133 are arranged vertically on each branch pipe 132. A drive pump 134 is disposed on the main pipe 131, which pumps cleaning fluid from the main pipe 131 into the multiple branch pipes 132 and sprays it onto the server to be cleaned through the nozzles 133 to clean the server.
[0042] Among them, main pipe 131 is mainly responsible for the input of cleaning fluid. Figure 2 In the specific embodiment shown, the cleaning device 130 also includes a liquid storage tank 135 disposed at the bottom of the cleaning chamber 113. The liquid storage tank 135 is used to store cleaning fluid. The main pipeline 131 is connected to the liquid storage tank 135 so that the drive pump 134 can pump the cleaning fluid in the liquid storage tank 135 into multiple branch pipelines 132 through the main pipeline 131, and finally spray it onto the server to be cleaned through the nozzle 133 to achieve cleaning of the server to be cleaned.
[0043] Of course, in some other embodiments, in order to minimize the number of parts and reduce the volume of the cabinet 110, a pipe interface can be directly set on the cabinet 110. The main pipe 131 is connected to the inside of the pipe interface. A cleaning fluid pipeline can be set in the data center or other working environment where the liquid-cooled cabinet 100 is located. The pipe interface is responsible for connecting the cleaning fluid pipeline to the outside, so that the drive pump 134 pumps the cleaning fluid in the cleaning fluid pipeline into multiple branch pipes 132 through the main pipe 131, and finally sprays it out through the nozzle 133.
[0044] Multiple branch pipes 132 are provided on at least two opposite sides within the cleaning chamber 113, primarily to better clean the server to be cleaned. Specifically, they can be arranged as follows: Figure 2 As shown, two branch pipes 132 are spaced apart on each side of the opposite sides inside the cleaning chamber 113. Since servers are generally flat, when the server to be cleaned is placed in the cleaning chamber 113, the two branch pipes 132 on each side face outwards towards the sides of a large surface of the server. This allows the cleaning fluid sprayed from the nozzles 133 on the branch pipes 132 to more comprehensively cover the surrounding area of the server, achieving better cleaning. Figure 2 This is merely one example provided in this application. In other embodiments, multiple branch pipes 132 may also surround the inside of the cleaning chamber 113, which can also achieve comprehensive cleaning of the server to be cleaned.
[0045] In addition to the vertically extending branch pipes 132, multiple nozzles 133 are arranged vertically on each branch pipe 132. This allows the cleaning fluid sprayed through the multiple nozzles 133 to more comprehensively cover the entire height of the server to be cleaned, ensuring a more thorough cleaning. Furthermore, to prevent excessive liquid splashing during cleaning and causing dirt to the opening 111 and cover plate 120, the nozzles 133 can be... Figure 2 The nozzle 133 is tilted downwards so that the cleaning fluid is sprayed downwards at an angle. On the one hand, after the cleaning fluid sprayed from the nozzle 133 hits the surface of the server to be cleaned, most of it will bounce off towards the bottom of the cleaning chamber 113, thereby minimizing the amount of cleaning fluid splashing onto the opening 111 and the cover plate 120 and causing dirt to spill out. On the other hand, the downward-spraying cleaning fluid can better push the oil-based coolant or other types of coolant on the surface of the server to be cleaned, causing it to slide down the outer wall of the server to be cleaned to the bottom of the cleaning chamber 113, thereby achieving a better cleaning effect.
[0046] In summary, the liquid-cooled cabinet 100 provided in this application embodiment has a liquid-cooled cavity 112 and a cleaning cavity 113 separated from each other inside the cabinet 110. The liquid-cooled cavity 112 is responsible for cooling during server operation. The server to be cleaned in the liquid-cooled cavity 112 can be directly transferred to the cleaning cavity 113 for cleaning between maintenance, without having to be transferred to a cleaning room or other equipment for cleaning. This effectively avoids the situation where coolant drips from the server to be cleaned, causing environmental contamination. In addition, the cleaning device 130 in the cleaning cavity 113 has multiple branch pipes 132 arranged opposite to each other on at least two sides. The multiple branch pipes 132 extend vertically, and each branch pipe 132 has multiple nozzles 133 arranged vertically to ensure that the cleaning fluid sprayed by the nozzles 133 can fully cover the server to be cleaned, thereby ensuring the cleaning effect of the server to be cleaned and providing a guarantee for subsequent server operation and maintenance.
[0047] To achieve the recycling of cleaning fluid and reduce resource waste, such as Figure 2 As shown, the cleaning device 130 may further include a return line 136, which is located at the bottom of the cleaning chamber 113 and communicates with the storage tank 135. The cleaning fluid sprayed from the nozzle 133 and finally falling to the bottom of the cleaning chamber 113 can flow back into the storage tank 135 through the return line 136, thus achieving the recycling of the cleaning fluid. Furthermore, the storage tank 135 may be equipped with a filling port and a drain port to facilitate the replacement of the cleaning fluid and the addition of cleaning agents.
[0048] Since the cleaning chamber 113 needs to house not only the server to be cleaned but also integrate the cleaning device 130, this application further proposes an implementation method to optimize the structural layout of the cleaning chamber 113. Please refer to the following for details. Figure 2 A partition 115 is provided inside the cleaning chamber 113, dividing the cleaning chamber 113 vertically into a first chamber 1131 and a second chamber 1132. The first chamber 1131 is located above the second chamber 1132. The first chamber 1131 is used to accommodate the server to be cleaned. A storage tank 135 and a main pipeline 131 are both located in the second chamber 1132. A branch pipeline 132 communicates with the main pipeline 131 in the second chamber 1132, and the branch pipeline 132 passes through the partition 115 in a sealed manner and extends into the first chamber 1131. A nozzle 133 is located on the portion of the branch pipeline 132 located in the first chamber 1131. A return port 1151 is provided on the partition 115, and a return pipeline 136 is located in the second chamber 1132, with both ends of the return pipeline 136 communicating with the return port 1151 and the storage tank 135, respectively.
[0049] The partition 115 divides the internal space of the cleaning chamber 113. The upper first chamber 1131 serves as the space to accommodate the server to be cleaned, and it is equipped with branch pipes 132 and nozzles 133 to directly participate in the cleaning work. During the cleaning process, the first chamber 1131 will be filled with sprayed cleaning fluid. The lower second chamber 1132 provides the necessary space for the installation of other components in the cleaning device 130, so as to minimize the number of components to be installed in the first chamber 1131, and at the same time separate water-sensitive components such as circuit components from the first chamber 1131, thereby optimizing the overall space of the cleaning chamber 113 and ensuring the stability of the operation of each component.
[0050] In addition, such as Figure 2 As shown, the baffle 115 can be inclined so that the return port 1151 is at the lowest position of the baffle 115, and a collection box 1361 can be set at the position where the return pipe 136 communicates with the return port 1151, so that the mixture of cleaning fluid and coolant dripping on the baffle 115 can quickly flow to the return port 1151 and enter the collection box 1361, ensuring the return effect.
[0051] like Figure 1 and Figure 2 As shown, a controller 137 can also be installed in the second cavity 1132, and an operation panel 138 can be installed on the cabinet 110. The controller 137 is electrically connected to the operation panel 138 and the drive pump 134 respectively, so as to realize the switching control of the drive pump 134 through the operation panel 138.
[0052] To ensure the safety of the cleaning operation, such as Figure 1 As shown, the cover plate 120 may include a first cover plate 121 and a second cover plate 122. The first cover plate 121 covers the part of the opening 111 that corresponds to the liquid cooling chamber 112, and the second cover plate 122 covers the part of the opening 111 that corresponds to the cleaning chamber 113. The first cover plate 121 and the second cover plate 122 can be opened or closed relatively independently to ensure that when the server to be cleaned is being cleaned in the cleaning chamber 113, other servers in the liquid cooling chamber 112 can work normally and dissipate heat, thus ensuring the operating efficiency of the data center.
[0053] like Figure 2 As shown, a sensor 139 is provided on the cabinet 110 at a position corresponding to the second cover plate 122. The sensor 139 is electrically connected to the controller 137. The controller 137 is used to detect the opening and closing state of the second cover plate 122 through the sensor 139, and control the operation of the drive pump 134 according to the opening and closing state of the second cover plate 122.
[0054] The sensor 139 can be a mechanical press contact or an optical sensor. When the server to be cleaned is placed in the cleaning chamber 113 and the second cover 122 is closed, and the cleaning operation is started via the operation panel 138, the sensor 139 will first detect whether the second cover 122 is closed properly. If the second cover 122 is closed properly, the controller 137 will control the drive pump 134 to work to clean the server. If the second cover 122 is not closed properly, feedback will be given through the operation panel 138 display, indicator light illumination, or speaker beeping. Once the second cover 122 is closed properly, the drive pump 134 will be controlled to work. During the cleaning process, the controller 137 will also monitor the opening and closing status of the second cover 122 in real time through the sensor 139. If the second cover 122 is opened during the cleaning process, the controller 137 will immediately control the drive pump 134 to stop working to prevent cleaning fluid splashing.
[0055] To ensure that servers requiring cleaning can be quickly maintained and repaired after cleaning, such as Figure 2 As shown, the liquid-cooled cabinet 100 also includes multiple drying devices 140. These drying devices 140 can be fans as illustrated or heating devices, used to dry the liquid droplets on the cleaned server surface via airflow or heating. The multiple drying devices 140 are disposed on at least two sides of the cleaning chamber 113, for example, as shown in the diagram. Figure 2 The two large surfaces of the server to be cleaned are arranged on opposite sides inside the cleaning chamber 113 to quickly dry the server after cleaning. After drying, the server can be taken out of the cleaning chamber 113 for inspection and maintenance.
[0056] In order to ensure that the server to be cleaned is stably placed in the cleaning chamber 113, and to prevent the bottom of the server from contacting the bottom wall of the cleaning chamber 113 and affecting the cleaning effect, such as Figure 2 As shown, a server fixing component 150 can be installed in the cleaning chamber 113. For example, it can be a fixing plate or fixing platform that is fixedly connected to the hanging ears on the server to be cleaned. After the server fixing component 150 fixes the server to be cleaned, the bottom of the server to be cleaned can be suspended in the air to ensure the cleaning effect of the bottom. At the same time, it can also prevent the server to be cleaned from shaking during the cleaning process, thereby preventing damage to the internal components of the server to be cleaned.
[0057] According to another aspect of the embodiments of this application, a liquid cooling system is provided, which includes the liquid cooling cabinet 100 in any of the above embodiments.
[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application. In particular, as long as there is no structural conflict, the various technical features mentioned in the various embodiments can be combined in any way.
