Description
Liquid cooling cabinet
[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on September 26, 2022, with application number 202211176173X and application name “Liquid Cooling Cabinet”, the entire contents of which are incorporated by reference into this application. Technical Field
[0002] The present application relates to the technical field of cooling technology, and in particular to a liquid cooling cabinet. Background Art
[0003] In the era of big data, more and more companies in sectors such as finance, telecommunications, and power are establishing their own data centers to meet increasingly demanding user data and service requirements. Data centers host a large number of IT (Internet Technology) devices. For example, IT equipment can include servers, switches, routers, and other critical electronic equipment. These devices generate significant amounts of heat during operation.
[0004] Liquid-cooled cabinets use liquid cooling technology to cool IT equipment. Liquid cooling uses a refrigerant to remove most of the heat, achieving heat dissipation and cooling. Immersion cooling is a common cooling method within this technology. Immersion cooling allows the refrigerant to fully cover the entire IT equipment, achieving uniform heat exchange and cooling.
[0005] In related technologies, multiple IT devices are placed inside a liquid-cooled cabinet. The refrigerant liquid can completely immerse the IT equipment. Liquid-cooled cabinets are usually equipped with a top cover. As the refrigerant liquid dissipates heat and cools the IT equipment, gaseous refrigerant exists between the liquid level of the refrigerant liquid in the liquid-cooled cabinet and the top cover. When maintenance personnel perform maintenance on the liquid-cooled cabinet or IT equipment, they need to open the top cover of the liquid-cooled cabinet. At this time, the gaseous refrigerant easily evaporates into the air, resulting in gaseous refrigerant loss, which may even pollute the environment or pose a health risk to maintenance personnel.
[0006] Summary of the Invention
[0007] The present application provides a liquid-cooled cabinet that can solve the problem of gaseous refrigerant evaporating from the inside of the cabinet to the external environment during maintenance by maintenance personnel, resulting in gaseous refrigerant loss, environmental pollution, or affecting the health of maintenance personnel.
[0008] The present application provides a liquid cooling cabinet, comprising:
[0009] The cabinet body includes a receiving space with an opening, and the cabinet body also includes a bottom plate and side plates, the opening corresponds to the bottom plate, and the bottom plate is provided with a liquid inlet pipe;
[0010] An independent compartment is located in the accommodating space, and the independent compartment has an equipment accommodating cavity;
[0011] A connector connects the liquid inlet pipe and the equipment accommodating chamber. The connector is located in the accommodating space. The connector includes a first connecting member and a second connecting member. The first connecting member is arranged on the liquid inlet pipe, and the second connecting member is arranged on an independent compartment. The first connecting member and the second connecting member are detachably connected.
[0012] The liquid-cooled cabinet provided herein has an independent compartment for accommodating IT equipment. When the first connector and the second connector are connected, refrigerant liquid can flow through the liquid inlet pipe, through the first and second connectors, and into the interior of the independent compartment. The refrigerant liquid can completely immerse the IT equipment, thereby dissipating heat generated during operation, thereby achieving a cooling effect on the IT equipment. This helps reduce the possibility of high temperatures during IT equipment operation, which could affect its performance.
[0013] Refrigerant liquids often generate gaseous refrigerant when cooling IT equipment. This gaseous refrigerant can be contained within the equipment compartment. This prevents it from escaping from the independent compartments and escaping into the air even when maintenance personnel open the cabinet. This helps minimize gaseous refrigerant loss and reduces the possibility of gaseous refrigerant escaping to the outside world, potentially polluting the environment or harming the health of maintenance personnel.

These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION
[0060] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
[0061] The liquid cooling cabinet 10 is a cabinet that uses liquid cooling technology to cool down IT equipment 20. Common liquid cooling technologies include cold plate cooling technology and immersion cooling technology.
[0062] In cold plate cooling technology, a heat transfer plate is installed in the key heat dissipation area of the IT equipment 20. A refrigerant liquid can flow inside the heat transfer plate, allowing the refrigerant liquid to conduct heat away from the key heat dissipation area of the IT equipment 20, achieving a cooling effect. The key heat dissipation area refers to the area of the IT equipment 20 that dissipates the most heat during operation. The key heat dissipation area is a localized area.
[0063] In immersion cooling technology, the entire IT equipment 20 can be completely immersed in a refrigerant liquid. The refrigerant liquid can absorb the heat generated during the operation of the IT equipment 20 to reduce the heat of the IT equipment 20.
[0064] The refrigerant liquid has insulation, non-conductivity and good heat dissipation. Exemplarily, the refrigerant liquid can be a fluorinated liquid.
[0065] The liquid cooling cabinet 10 of the present application can achieve the effect of heat dissipation and cooling of IT equipment 20 through immersion cooling technology. In the related art, multiple IT equipment 20 are placed inside the liquid cooling cabinet. The refrigerant liquid can completely immerse the IT equipment 20. The liquid cooling cabinet is usually equipped with an upper cover. In the process of the refrigerant liquid dissipating heat and cooling the IT equipment 20, there is gaseous refrigerant between the liquid level of the refrigerant liquid in the liquid cooling cabinet and the upper cover. When maintenance personnel maintain the liquid cooling cabinet or IT equipment 20, they need to open the upper cover of the liquid cooling cabinet. At this time, the gaseous refrigerant is easy to evaporate into the air, resulting in the loss of the gaseous refrigerant, and may even pollute the environment or bring health risks to the maintenance personnel.
[0066] Based on the above problems, the applicant has improved the structure of the liquid cooling cabinet 10 , and the embodiments of the present application are further described below.
[0067] 1 to 3 , the liquid cooling cabinet 10 of the embodiment of the present application includes a cabinet body 100 , an independent compartment 110 and a connector 120 .
[0068] The cabinet 100 includes a storage space 100a having an opening. The cabinet 100 also includes a bottom plate 101 and a side plate 102. The opening corresponds to the bottom plate 101, and the bottom plate 101 is provided with a liquid inlet pipe 103. The independent compartment 110 is located in the storage space 100a. The independent compartment 110 has an equipment storage cavity 110a. The connector 120 connects the liquid inlet pipe 103 and the equipment storage cavity 110a. The connector 120 is located in the storage space 100a. The connector 120 includes a first connecting member 121 and a second connecting member 122. The first connecting member 121 is provided on the liquid inlet pipe 103. The second connecting member 122 is provided on the independent compartment 110. The first connecting member 121 and the second connecting member 122 are detachably connected.
[0069] The independent compartment 110 of the present application can be used to house IT equipment 20. When the first connector 121 and the second connector 122 are connected, refrigerant liquid can flow through the first connector 121 and the second connector 122 via the liquid inlet pipe 103 and enter the interior of the independent compartment 110. The refrigerant liquid can completely immerse the IT equipment 20, thereby dissipating the heat generated during the operation of the IT equipment 20, thereby achieving a heat dissipation and cooling effect on the IT equipment 20, which helps to reduce the possibility of high temperatures during the operation of the IT equipment 20 and affecting its operating performance.
[0070] The refrigerant liquid easily generates gaseous refrigerant during the process of dissipating heat and cooling the IT equipment 20. The gaseous refrigerant can be located within the equipment accommodating chamber 110a. Therefore, even if maintenance personnel open the cabinet 100, the gaseous refrigerant is unlikely to evaporate from the interior of the independent compartment 110 into the air. This helps to reduce the loss of gaseous refrigerant and the possibility of gaseous refrigerant evaporating into the external environment, causing environmental pollution or affecting the health of maintenance personnel.
[0071] In some achievable embodiments, as shown in FIG4 , the independent compartment 110 of an embodiment of the present application includes a compartment body 111 and a cover body 112. The compartment body 111 and the cover body 112 are sealed and connected. The compartment body 111 and the cover body 112 form an equipment accommodating chamber 110a. The cover body 112 is located at the top of the compartment body 111. The second connecting member 122 is provided at the bottom of the compartment body 111. Along the height direction X of the cabinet 100, the first connecting member 121 is plugged into the second connecting member 122.
[0072] The compartment body 111 and the cover body 112 of the embodiment of the present application can be sealed and connected to form a sealed equipment accommodating chamber 110a, thereby reducing the possibility of maintenance personnel opening the cabinet 100 and causing volatilization of gaseous refrigerant.
[0073] In some examples, since the partition body 111 and the cover body 112 are sealed together, even if maintenance personnel open the cabinet 100, the gaseous refrigerant is not easy to evaporate from the independent partition 110 into the air. Therefore, the cabinet 100 of the liquid cooling cabinet 10 does not need to be additionally provided with a sealing structure, and even the upper cover for sealing the cabinet 100 can be eliminated, which is beneficial to reducing the processing cost of the liquid cooling cabinet 10.
[0074] In some examples, as shown in Figures 5 and 6, one end of the compartment body 111 has an opening. The cover 112 can be used to cover the opening. Exemplarily, the compartment body 111 and the cover 112 can be connected by a snap. Exemplarily, a snap-fit portion 110b is provided on the compartment body 111. A snap-fit portion 110c is provided on the cover 112. When the snap-fit portion 110c and the snap-fit portion 110b are snap-fitted together, the cover 112 can cover the compartment body 111 to seal the device accommodating cavity 110a.
[0075] In some examples, a sealing ring may be provided between the compartment body 111 and the cover 112 along the height direction X. When the engaging portion 110c and the engaging portion 110b are engaged with each other, the cover 112 may compress the sealing ring, thereby improving the sealing effect of the device accommodating chamber 110a.
[0076] In some examples, the cover 112 may be a transparent structure, and maintenance personnel may observe the operating status of the internal IT equipment 20 through the transparent cover 112 .
[0077] In some examples, as shown in FIG3 , the first connector 121 may include a cylindrical plug. The cylindrical plug may include a first through-hole 121 a. The second connector 122 may include a cylindrical socket. The cylindrical socket may include a second through-hole 122 a. Along the height direction X, the cylindrical plug may face upward, and the cylindrical socket may face downward. The cylindrical plug and the cylindrical socket may be arranged correspondingly, so that when maintenance personnel place the independent compartment 110 into the accommodating space 100 a, the cylindrical plug can be easily inserted into the interior of the cylindrical socket, which is conducive to improving maintenance efficiency.
[0078] In some examples, at least a portion of the cylindrical plug can be inserted into the second through-hole 122a along the height direction X. The first through-hole 121a and the second through-hole 122a can be arranged along the height direction X, and the liquid inlet pipe 103, the first through-hole 121a, the second through-hole 122a, and the device-receiving chamber 110a of the independent compartment 110 can be interconnected. The refrigerant liquid in the liquid inlet pipe 103 can enter the device-receiving chamber 110a through the first through-hole 121a and the second through-hole 122a.
[0079] In some implementations, as shown in FIG5 , the embodiment of the present application can include multiple independent compartments 110. The multiple independent compartments 110 are arranged in parallel along the length direction Y of the cabinet 100. Each independent compartment 110 is connected to the liquid inlet pipe 103 via multiple connectors 120, which are spaced apart along the width direction Z of the cabinet 100.
[0080] An IT device 20 can be provided inside each independent compartment 110 of the embodiment of the present application. The liquid cooling cabinet 10 can accommodate multiple independent compartments 110. It should be noted that the refrigerant liquid between the multiple independent compartments 110 cannot be intercommunication. When the independent compartment 110 is placed in the accommodating space 100a, the first connecting member 121 is connected to the second connecting member 122. At this time, the refrigerant liquid can flow through the first connecting member 121 and the second connecting member 122 through the liquid inlet pipe 103 into the interior of the independent compartment 110 to dissipate heat and cool the IT equipment 20. When it is necessary to maintain the IT equipment 20 in one of the independent compartments 110, the independent compartment 110 can be taken out from the accommodating space 100a. At this time, the second connecting piece 122 of the independent compartment 110 and its corresponding first connecting piece 121 are disconnected, and the refrigerant liquid in the liquid inlet pipe 103 will no longer continue to input refrigerant liquid into the independent compartment 110. On the one hand, this can reduce the consumption of refrigerant liquid, which is beneficial to reducing the cost of the liquid cooling cabinet 10; on the other hand, it will not affect the normal operation of other IT equipment 20.
[0081] In some examples, the independent compartments 110 can be evenly distributed within the storage space 100a, so that more independent compartments 110 can be provided within the limited storage space 100a, thereby cooling more IT equipment 20. Furthermore, the refrigerant liquid only needs to be provided within the independent compartments 110, which can maximize the utilization of the refrigerant liquid and help save refrigerant liquid.
[0082] In some examples, as shown in FIG5 , multiple independent compartments 110 can be arranged side by side along the length direction Y. Furthermore, along the width direction Z, each independent compartment 110 can be connected to the cabinet 100 via three connectors 120. Accordingly, the number of liquid inlet pipes 103 can also be three. The liquid inlet pipes 103 can extend along the length direction Y.
[0083] In some examples, the size of the independent compartment 110 can be set according to the size of the IT equipment 20. The accommodation space 100a can accommodate multiple independent compartments 110 of different sizes, thereby providing a cooling function for a variety of different IT equipment 20.
[0084] In some possible implementations, as shown in FIG5 , the cabinet 100 of the embodiment of the present application includes two opposite side panels 102 . Along a height direction X of the cabinet 100 , the independent compartments 110 are slidably connected to the two opposite side panels 102 .
[0085] The independent compartment 110 of the embodiment of the present application can slide into the accommodation space 100a through the opening, thereby making it convenient for maintenance personnel to disassemble and assemble the independent compartment 110.
[0086] In some examples, a plurality of independent compartments 110 may be arranged side by side along the length direction Y, and thus, both sides of the independent compartments 110 along the width direction Z may be slidably connected to the two side panels 102 .
[0087] In some embodiments, as shown in Figures 5 and 7 , the liquid cooling cabinet 10 according to an embodiment of the present application includes a slide rail 130. The slide rail 130 is disposed on a surface of the side panel 102 facing the storage space 100a. The slide rail 130 is disposed along the height direction X. The independent compartment 110 includes a slide groove 113. The slide groove 113 is disposed corresponding to the slide rail 130. The slide rail 130 can slide along the slide groove 113. At least a portion of the slide rail 130 is located within the slide groove 113.
[0088] The slide groove 113 of the embodiment of the present application has a guiding function. The slide groove 113 can be set along the height direction X. The slide groove 113 can be set on the outer surface of the partition body 111 and be recessed in the direction of the equipment accommodating cavity 110a. The slide rail 130 can slide along the slide groove 113 so that the independent partition 110 can slide vertically along the height direction X, thereby, on the one hand, reducing the possibility that the independent partition 110 deflects in the horizontal direction, making it difficult to align the second connecting member 122 with the first connecting member 121. On the other hand, when the liquid cooling cabinet 10 is provided with a plurality of independent partitions 110, it can reduce the possibility that one of the independent partitions 110 is installed obliquely in the accommodating space 100a, resulting in occupying the position of other independent partitions 110 and unreasonable utilization of the accommodating space 100a.
[0089] In some examples, as shown in Figures 4 and 8, the slide rail 130 may include a first roller 131 and a second roller 132. The axis of the first roller 131 and the axis of the second roller 132 may be arranged to intersect. Along the length direction Y, the second roller 132 may be respectively provided on both sides of the first roller 131. The slide 113 may include a bottom wall 1131 and two inner walls 1132. The two inner walls 1132 are arranged opposite to each other along the length direction Y. The bottom wall 1131 may be arranged facing the side panel 102. The first roller 131 is slidably connected to the bottom wall 1131. The second roller 132 is slidably connected to the inner wall 1132.
[0090] For example, the number of the first rollers 131 and the number of the second rollers 132 can both be multiple. The multiple first rollers 131 can be spaced apart along the height direction X. The multiple second rollers 132 can also be spaced apart along the height direction X.
[0091] In some embodiments, as shown in Figures 2 and 9 , the independent compartment 110 of the present embodiment includes a current balancing module 114. The current balancing module 114 is located within the compartment body 111. The current balancing module 114 is disposed corresponding to the second connector 122. Along the height direction X, the current balancing module 114 and the second connector 122 are spaced apart.
[0092] Along the height direction X, the refrigerant liquid that enters the bottom of the independent compartment 110 through the second connecting member 122 can gradually and evenly cover the IT equipment 20 upward after passing through the flow equalization module 114, so that the refrigerant liquid can be in uniform contact with the IT equipment 20, which is beneficial to reduce the possibility of uneven contact between the IT equipment 20 and the refrigerant liquid, affecting the cooling effect of the IT equipment 20.
[0093] In some examples, when the IT equipment 20 is placed inside the independent compartment 110 , along the height direction X, the bottom end of the IT equipment 20 is spaced apart from the current balancing module 114 .
[0094] In some examples, the current balancing module 114 is evenly provided with a plurality of through holes.
[0095] In some embodiments, as shown in FIG9 , the compartment body 111 includes two opposing sidewalls 1111. The independent compartment 110 further includes a liquid outlet 210 connector 115 and a gas outlet connector 116. The liquid outlet 210 connector 115 and the gas outlet connector 116 are respectively disposed on the two sidewalls 1111. Along the height direction X, the liquid outlet 210 connector 115 and the gas outlet connector 116 are disposed near the cover 112. The height of the gas outlet connector 116 is greater than the height of the liquid outlet connector 115.
[0096] The connector 120 of the embodiment of the present application can be located at the bottom of the independent compartment 110. The refrigerant liquid can enter the interior of the independent compartment 110 through the connector 120. It should be noted that the temperature of the refrigerant liquid entering the independent compartment 110 through the connector 120 is relatively low. Along the height direction X, the refrigerant liquid with a lower temperature can gradually flow upward and absorb the heat generated during the operation of the IT equipment 20. After the refrigerant liquid with a lower temperature absorbs heat, its own temperature will become higher. When the temperature of the refrigerant liquid reaches a preset value, the refrigerant liquid can be discharged through the connector of the liquid outlet 210. It should be noted that the temperature of the refrigerant liquid discharged through the liquid outlet 210 is relatively high. At the same time, the liquid inlet pipe 103 can continue to input refrigerant liquid with a lower temperature to the independent compartment 110 through the connector 120, and circulate it in this way, so as to achieve cooling treatment during the operation of the IT equipment 20.
[0097] After the coolant liquid absorbs heat, its temperature will increase, and part of the coolant liquid will be converted into gaseous refrigerant. When the gaseous refrigerant reaches saturation, the gaseous refrigerant can be discharged through the outlet connector 116.
[0098] The height of the gas outlet joint 116 in the embodiment of the present application may be greater than the height of the liquid outlet joint 115 , thereby reducing the possibility of the refrigerant liquid being discharged through the gas outlet joint 116 .
[0099] In some examples, the flow rate of the refrigerant liquid entering through the connector 120 can be the same as the flow rate discharged through the liquid outlet joint 115 to ensure the stability of the liquid level height of the refrigerant liquid in the independent compartment 110, thereby improving the stability of the cooling effect of the refrigerant liquid on the IT equipment 20.
[0100] In some examples, the independent compartment 110 may be equipped with a safety valve. If the refrigerant gas in the independent compartment 110 becomes saturated and is not promptly discharged through the outlet connector 116, the air pressure in the independent compartment 110 may gradually increase. The safety valve can maintain stable air pressure inside and outside the independent compartment 110, reducing the possibility of high pressure inside the independent compartment 110 causing a malfunction of the liquid cooling cabinet 10.
[0101] In some examples, along the width direction Z, as shown in FIG9 , a lifting lug 119 may be provided on the cover 112 of the independent compartment 110. The lifting lug 119 may be used to lift the independent compartment 110. When maintenance of the independent compartment 110 is required, the independent compartment 110 may be first lifted by the lifting lug 119 and inverted, and then the refrigerant liquid inside the independent compartment 110 may be extracted through the liquid outlet connector 115. At this time, the safety valve may reduce the possibility of deformation of the independent compartment 110 due to excessive extraction of the refrigerant liquid, which may cause the internal air pressure of the independent compartment 110 to be lower than the external air pressure.
[0102] In some implementations, as shown in Figures 2 and 5 , the liquid cooling cabinet 10 includes a liquid outlet pipe 140, a liquid outlet collector 150, and a first liquid collecting tank 160. The liquid outlet pipe 140, the liquid outlet collector 150, and the first liquid collecting tank 160 are located within the cabinet 100. Along the height direction X, the first liquid collecting tank 160 is correspondingly disposed below the liquid outlet connector 115, the liquid outlet pipe 140, and the liquid outlet collector 150.
[0103] In some examples, the liquid outlet connector 115 and the liquid outlet pipe 140 can be connected to a first connection. The liquid outlet pipe 140 and the liquid outlet collector 150 can be connected to a second connection. A first sump 160 can be disposed below the first connection and the second connection, respectively. When refrigerant liquid leaks from the first connection or the second connection, the leaked refrigerant liquid can fall into the first sump 160 below, making it easier for maintenance personnel to clean up the leaked refrigerant liquid, thereby ensuring a clean and tidy environment within the liquid cooling cabinet 10.
[0104] In some examples, a liquid leakage sensor may be provided on the surface of the first sump 160 facing the first connection and the second connection. When refrigerant liquid falls into the first sump 160, the liquid leakage sensor may send an indication signal, so that maintenance personnel can promptly check the cause of the leakage to reduce the loss of refrigerant liquid.
[0105] In some implementations, as shown in Figures 2 and 5 , the liquid cooling cabinet 10 further includes an air outlet pipe 170, an air outlet collector 180, and a second liquid collecting tank 190. The air outlet connector 116, the air outlet pipe 170, and the air outlet collector 180 are located inside the cabinet 100. Along the height direction X, the second liquid collecting tank 190 is correspondingly disposed below the air outlet connector 116, the air outlet pipe 170, and the air outlet collector 180.
[0106] In some examples, the air outlet connector 116 and the air outlet pipe 170 can be connected to the third connection. The air outlet pipe 170 and the air outlet collector 180 can be connected to the fourth connection. In the process of the gaseous refrigerant being discharged through the air outlet interface, there is a possibility that the refrigerant liquid is also discharged through the air outlet interface. The second collecting tank 190 can be correspondingly arranged below the third connection and the fourth connection, so that when the refrigerant liquid leaks at the third connection or the fourth connection, the leaked refrigerant liquid can fall into the second collecting tank 190, which can facilitate maintenance personnel to clean up the leaked refrigerant liquid to ensure that the internal environment of the liquid cooling cabinet 10 is clean and tidy.
[0107] In some examples, a liquid leakage sensor may be provided on the surface of the second liquid collecting tank 190 facing the third connection and the fourth connection. When refrigerant liquid falls into the second liquid collecting tank 190, the liquid leakage sensor may send an indication signal, so that maintenance personnel can promptly check the cause of the leakage to reduce the loss of refrigerant liquid.
[0108] In some examples, first sump 160 and second sump 190 may be in communication with each other.
[0109] In some examples, the side panel 102 of the liquid cooling cabinet 10 may be provided with a liquid inlet 200, a liquid outlet 210, and an air extraction interface 220. The liquid inlet 200, the liquid outlet 210, and the air extraction interface 220 may all be located on the same side panel 102. The liquid inlet 200 is connected to the liquid inlet pipe 103. The liquid outlet 210 is connected to the liquid outlet collector 150. The air extraction interface 220 is connected to the air outlet collector 180.
[0110] In summary, the working principle of the liquid cooling cabinet 10 of the embodiment of the present application is as follows. The refrigerant liquid with a lower temperature flows through the liquid inlet 200 through the liquid inlet pipe 103 and the connector 120 into the interior of the independent compartment 110. Along the height direction X, the refrigerant liquid with a lower temperature gradually flows upward to absorb the heat emitted by the IT equipment 20. After the refrigerant liquid with a lower temperature absorbs the heat, its own temperature gradually increases. When the temperature of the refrigerant liquid reaches a preset value. The refrigerant liquid with a higher temperature can flow through the liquid outlet joint 115 through the liquid outlet pipe 140 and merge into the liquid outlet collector 150, and finally flow out to the outside of the liquid cooling cabinet 10 through the liquid outlet 210.
[0111] At the same time, the refrigerant liquid absorbs heat to generate gaseous refrigerant. When the gaseous refrigerant is saturated, the gaseous refrigerant can be collected into the gas collector 180 through the gas outlet connector 116 and the gas outlet pipe 170, and finally discharged to the outside of the liquid cooling cabinet 10 through the gas extraction interface 220.
[0112] 5 , the liquid cooling cabinet 10 includes a third liquid collecting tank 230 . The third liquid collecting tank 230 is disposed on a side of the liquid inlet pipe 103 facing the independent compartment 110 . The first connector 121 is located inside the third liquid collecting tank 230 .
[0113] The third liquid collecting tank 230 of the embodiment of the present application can be used to accommodate the refrigerant liquid leaked between the first connector 121 and the second connector 122. This makes it easier for maintenance personnel to clean up the leaked refrigerant liquid, ensuring a clean and tidy environment inside the liquid cooling cabinet 10.
[0114] In some examples, the third liquid collecting trough 230 is arranged along the length direction Y. The third liquid collecting trough 230 is arranged corresponding to the liquid inlet pipe 103. For example, the number of the third liquid collecting trough 230 and the liquid inlet pipe 103 is the same, and both can be set to three.
[0115] In some examples, a liquid leakage sensor may be provided on the third liquid collecting tank 230. The liquid leakage sensor may send an indication signal so that maintenance personnel can check the cause of the liquid leakage in a timely manner to reduce the loss of the refrigerant liquid.
[0116] In some feasible embodiments, as shown in Figures 5 and 9 , the independent compartment 110 includes a high-voltage outlet 117 and a low-voltage outlet 118. Along the width direction Z, the high-voltage outlet 117 and the low-voltage outlet 118 are respectively provided on two side walls 1111.
[0117] Along the height direction X, a high-voltage cable 240 and a low-voltage cable 250 may be provided on the top of the IT equipment 20. Along the width direction Z, the high-voltage cable 240 and the low-voltage cable 250 may be arranged at intervals. The liquid cooling cabinet 10 includes a power distribution management unit 260 (Power Distribution Unit, PDU). The power distribution management unit 260 has power distribution and management functions. The high-voltage cable 240 may pass through the high-voltage outlet 117 and be connected to the power distribution management unit 260 of the liquid cooling cabinet 10. The low-voltage cable 250 may pass through the low-voltage outlet 118 and pass out of the independent compartment 110.
[0118] In some examples, the high-power cables 240 of multiple IT devices 20 can all be plugged into the power distribution management unit 260 .
[0119] In some examples, the high-voltage power outlet 117 and the liquid outlet connector 115 can be disposed on the same side panel 102. Along the height direction X, the high-voltage power outlet 117 can be higher than the liquid outlet connector 115, thereby reducing the possibility that the liquid outlet connector 115 is located at the upper end of the high-voltage power outlet 117 and leaks refrigerant liquid from the liquid outlet connector 115, thereby soaking the high-voltage power cable 240.
[0120] In some examples, the low-voltage outlet 118 and the air outlet connector 116 may be provided on the same side panel 102 .
[0121] In some examples, the liquid cooling cabinet 10 may further include a weak current cable management trough. The weak current cable management trough may be used to organize the plurality of weak current cables 250 extending from the plurality of independent compartments 110. The weak current cable management trough may be provided corresponding to the weak current cable outlet 118.
[0122] In some implementations, as shown in FIG10 , the liquid-cooled cabinet 10 of the present application can be configured with a coolant distribution unit (CDU) 30. The CDU 30 can regulate the temperature of the refrigerant liquid. The CDU 30 can be positioned side by side with the liquid-cooled cabinet 10. The CDU 30 can include a heat exchanger 310 and a gas collection container 320.
[0123] In some examples, one end of the heat exchanger 310 can be connected to the liquid outlet 210, and the other end can be connected to the liquid inlet 200. The high-temperature refrigerant liquid flowing out of the liquid outlet 210 can be converted into a low-temperature refrigerant liquid after passing through the heat exchanger 310, and can flow back into the independent compartment 110 through the liquid inlet 200 to cool the IT equipment 20, and can be circulated in sequence.
[0124] In some examples, one end of the heat exchanger 310 may be connected to a water pump 330. The water pump 330 may be used to transport the refrigerant liquid. For example, the water pump 330 may be a variable frequency pump or a magnetic pump.
[0125] In some examples, the gas collection container 320 has a sealed space. The gas collection container 320 can be connected to the gas extraction interface 220. The gas collection container 320 can be used to collect gaseous refrigerant for centralized processing, thereby reducing the possibility of gaseous refrigerant volatilizing into the outside air, causing environmental pollution or affecting the health of maintenance personnel.
[0126] In some examples, a vacuum pump 340 may be provided between the gas collecting container 320 and the gas extraction interface 220 . The vacuum pump 340 may be used to extract the gaseous refrigerant in the independent compartment 110 and transfer the gaseous refrigerant to the gas collecting container 320 .
