Description

Technical Field

[0001] The present application relates to the field of cooling technology, and in particular to a liquid cooling cabinet. Background Art

[0002] In the era of big data, more and more companies in finance, communications, and electricity have begun to have their own data centers to meet the increasingly stringent data and service challenges of users. There are a large number of IT (Internet Technology) devices in the data center. For example, IT equipment can be key electronic equipment such as servers, switches, and routers. IT equipment emits a lot of heat during operation.

[0003] Liquid-cooled cabinets are cabinets that use liquid cooling technology to cool IT equipment. Liquid cooling technology can remove most of the heat through the refrigerant liquid to achieve heat dissipation and cooling. Immersion liquid cooling is a commonly used cooling technology in liquid cooling technology. Immersion liquid cooling allows the refrigerant liquid to fully cover the entire IT equipment to achieve a uniform heat exchange cooling effect.

[0004] In the related art, multiple IT equipment are placed inside a liquid cooling cabinet. The refrigerant liquid can completely immerse the IT equipment. The liquid cooling cabinet is usually equipped with an upper cover. During the process of the refrigerant liquid dissipating heat and cooling the IT equipment, there is gaseous refrigerant between the liquid surface of the refrigerant liquid in the liquid cooling cabinet and the upper cover. When maintenance personnel perform maintenance on the liquid cooling cabinet or IT equipment, 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.

These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0056] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0057] The liquid cooling cabinet 10 is a cabinet that uses liquid cooling technology to cool down the IT equipment 20. Common liquid cooling technologies include cold plate cooling technology and immersion cooling technology.

[0058] In the cold plate cooling technology, a heat conducting plate is provided in the key heat dissipation area of ​​the IT equipment 20. A flowing refrigerant liquid can be provided inside the heat conducting plate, so that the refrigerant liquid can conduct the heat of the key heat dissipation area of ​​the IT equipment 20 to achieve the effect of heat dissipation and cooling. Among them, the key heat dissipation area refers to the area where the IT equipment 20 dissipates a large amount of heat during operation. The key heat dissipation area is a local area.

[0059] In the immersion cooling technology, the entire IT device 20 can be completely immersed in the refrigerant liquid. The refrigerant liquid can absorb the heat generated during the operation of the IT device 20 to reduce the heat of the IT device 20.

[0060] The refrigerant liquid has insulation, non-conductivity and good heat dissipation. Exemplarily, the refrigerant liquid can be a fluorinated liquid.

[0061] The liquid cooling cabinet 10 of the present application can achieve the effect of heat dissipation and cooling the 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 surface 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.

[0062] Based on the above problems, the applicant has improved the structure of the liquid cooling cabinet 10. The embodiments of the present application are further described below.

[0063] See also Figures 1 to 3 As shown, 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

[0064] 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 chamber 110a. The connector 120 connects the liquid inlet pipe 103 and the equipment storage chamber 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.

[0065] The independent compartment 110 of the present application can be used to place IT equipment 20. When the first connector 121 is connected to the second connector 122, the refrigerant liquid can flow through the first connector 121 and the second connector 122 through the liquid inlet pipe 103 and enter the interior of the independent compartment 110. The refrigerant liquid can completely immerse the IT equipment 20, so that the heat generated during the operation of the IT equipment 20 can be guided out to achieve the effect of heat dissipation and cooling of the IT equipment 20, which is conducive to reducing the possibility of high temperature during the operation of the IT equipment 20, affecting the working performance.

[0066] Gaseous refrigerant is easily generated in the process of cooling the IT equipment 20 by the refrigerant liquid. The gaseous refrigerant can be located in the equipment accommodating chamber 110a, so that even if the maintenance personnel open the cabinet 100, the gaseous refrigerant is not easy to evaporate from the inside of the independent compartment 110 into the air, which is conducive to reducing the loss of the gaseous refrigerant and reducing the possibility of gaseous refrigerant evaporating to the external environment to pollute the environment or affect the health of the maintenance personnel.

[0067] In some possible implementations, see Figure 4 As shown, the independent compartment 110 of the 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 arranged 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.

[0068] 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.

[0069] In some examples, since the partition body 111 and the cover body 112 are sealed and connected, even if the 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 used to close the cabinet 100 can be eliminated, which is beneficial to reduce the processing cost of the liquid cooling cabinet 10.

[0070] For some examples, see Figure 5 and Figure 6 As shown, one end of the compartment body 111 has an opening. The cover body 112 can be used to cover the opening. Exemplarily, the compartment body 111 and the cover body 112 can be connected by a snap. Exemplarily, a snap-fitting portion 110b is provided on the compartment body 111. A snap-fitting portion 110c is provided on the cover body 112. When the snap-fitting portion 110c is snapped with the snap-fitting portion 110b, the cover body 112 can cover the compartment body 111 to seal the device accommodating cavity 110a.

[0071] 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 clamping portion 110c and the engaging portion 110b are buckled with each other, the cover 112 may compress the sealing ring, thereby facilitating improving the sealing effect of the device accommodating chamber 110a.

[0072] 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 cover 112 of the transparent structure.

[0073] For some examples, see Figure 3As shown, the first connecting member 121 may include a columnar plug. The columnar plug may include a first through hole 121a. The second connecting member 122 may include a columnar socket. The columnar socket may include a second through hole 122a. Along the height direction X, the columnar plug may face upward, and the columnar socket may face downward. The columnar plug and the columnar socket may be arranged correspondingly, so that when the maintenance personnel put the independent compartment 110 into the accommodating space 100a, the columnar plug can be easily inserted into the inside of the columnar socket, which is conducive to improving maintenance efficiency.

[0074] In some examples, at least part of the cylindrical plug may be inserted into the second through hole 122a along the height direction X. The first through hole 121a and the second through hole 122a may 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 accommodating chamber 110a of the independent compartment 110 may be interconnected. The refrigerant liquid in the liquid inlet pipe 103 may enter the device accommodating chamber 110a through the first through hole 121a and the second through hole 122a.

[0075] In some possible implementations, see Figure 5 As shown, the number of independent compartments 110 in the embodiment of the present application is multiple. 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 through multiple connectors 120, and the connectors 120 are arranged at intervals along the width direction Z of the cabinet 100.

[0076] An IT device 20 may be arranged inside each independent compartment 110 of the embodiment of the present application. The liquid cooling cabinet 10 may accommodate multiple independent compartments 110. It should be noted that the refrigerant liquid between the multiple independent compartments 110 cannot communicate with each other. 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 not 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.

[0077] In some examples, the independent compartments 110 can be evenly arranged in the accommodation space 100a, so that more independent compartments 110 are arranged in the limited accommodation space 100a, so that more IT equipment 20 can be cooled. At the same time, the refrigerant liquid only needs to be arranged inside the independent compartments 110, and the utilization of the refrigerant liquid can be maximized, which is conducive to saving the refrigerant liquid.

[0078] For some examples, see Figure 5 As shown, a plurality of independent compartments 110 may be arranged in parallel along the length direction Y. And along the width direction Z, each independent compartment 110 may be connected to the cabinet 100 via three connectors 120. Correspondingly, the number of the liquid inlet pipes 103 may also be three. The liquid inlet pipe 103 may extend along the length direction Y.

[0079] 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 a plurality of independent compartments 110 of different sizes, thereby providing a cooling function for a variety of different IT equipment 20.

[0080] In some possible implementations, see Figure 5 As shown, the cabinet 100 of the embodiment of the present application includes two opposite side panels 102. Along the height direction X of the cabinet 100, the independent compartment 110 can be slidably connected to the two opposite side panels 102.

[0081] The independent compartment 110 of the embodiment of the present application can slide into the accommodation space 100a through the opening, so that maintenance personnel can easily disassemble and assemble the independent compartment 110.

[0082] 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 .

[0083] In some possible implementations, see Figure 5 and Figure 7 As shown, the liquid cooling cabinet 10 of the embodiment of the present application includes a slide rail 130. The slide rail 130 is arranged on the surface of the side plate 102 facing the accommodating space 100a. The slide rail 130 is arranged along the height direction X. The independent compartment 110 includes a slide groove 113. The slide groove 113 is arranged 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 inside the slide groove 113.

[0084] 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 compartment body 111 and be recessed in the direction of the equipment accommodating chamber 110a. The slide rail 130 can slide along the slide groove 113 so that the independent compartment 110 can slide down vertically along the height direction X, thereby reducing the possibility that the independent compartment 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 compartments 110, the possibility that one of the independent compartments 110 is obliquely installed in the accommodating space 100a, resulting in the occupation of the positions of other independent compartments 110 and unreasonable utilization of the accommodating space 100a can be reduced.

[0085] For some examples, see Figure 4 and Figure 8 As shown, 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 rollers 132 may be respectively arranged on both sides of the first roller 131. The slide groove 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 plate 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.

[0086] For example, the number of the first rollers 131 and the number of the second rollers 132 can both be set to be multiple. The multiple first rollers 131 can be arranged at intervals along the height direction X. The multiple second rollers 132 can also be arranged at intervals along the height direction X.

[0087] In some possible implementations, see Figure 2 and Fig. 9 As shown, the independent compartment 110 of the embodiment of the present application includes a current balancing module 114. The current balancing module 114 is located inside the compartment body 111. The current balancing module 114 is arranged corresponding to the second connecting member 122. Along the height direction X, the current balancing module 114 and the second connecting member 122 are arranged at intervals.

[0088] Along the height direction X, the refrigerant liquid that enters the bottom of the independent compartment 110 through the second connecting piece 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.

[0089] 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 .

[0090] In some examples, the current balancing module 114 is evenly provided with a plurality of through holes.

[0091] In some possible implementations, see Fig. 9 As shown, the compartment body 111 includes two opposite side walls 1111. The independent compartment 110 also includes a liquid outlet 210 joint 115 and a gas outlet joint 116. The liquid outlet 210 joint 115 and the gas outlet joint 116 are respectively arranged on the two side walls 1111. Along the height direction X, the liquid outlet 210 joint 115 and the gas outlet joint 116 are arranged close to the cover body 112. The height of the gas outlet joint 116 is greater than the height of the liquid outlet joint 115.

[0092] 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 relatively low temperature can gradually flow upward and absorb the heat generated during the operation of the IT equipment 20. After the refrigerant liquid with a relatively low temperature absorbs heat, its own temperature will increase. When the temperature of the refrigerant liquid reaches a preset value, the refrigerant liquid can be discharged through the joint 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 the refrigerant liquid with a relatively low temperature into the independent compartment 110 through the connector 120, and circulate it in this way, so as to achieve cooling treatment of the operation process of the IT equipment 20.

[0093] After the refrigerant liquid with a lower temperature absorbs heat, its own temperature will increase, and part of the refrigerant liquid will be converted into gaseous refrigerant. When the gaseous refrigerant reaches a saturated state, the gaseous refrigerant can be discharged through the outlet connector 116.

[0094] 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 .

[0095] 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 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.

[0096] In some examples, the independent compartment 110 may be provided with a safety valve. If the gaseous refrigerant in the independent compartment 110 is saturated and not discharged in time through the gas outlet connector 116, the air pressure in the independent compartment 110 will gradually increase. The safety valve can maintain the stability of the air pressure inside and outside the independent compartment 110, reducing the possibility of high pressure in the independent compartment 110 causing the liquid cooling cabinet 10 to malfunction.

[0097] In some examples, along the width direction Z, see Fig. 9 As shown, 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 the independent compartment 110 needs to be maintained, the independent compartment 110 may be lifted and inverted by the lifting lug 119 first, and then the refrigerant liquid inside the independent compartment 110 may be extracted through the liquid outlet joint 115. At this time, the safety valve may reduce the possibility that the internal air pressure of the independent compartment 110 is lower than the external air pressure after the refrigerant liquid is excessively extracted, and the independent compartment 110 may be deformed.

[0098] In some possible implementations, see Figure 2 and Figure 5 As shown, 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 inside the cabinet 100. Along the height direction X, the first liquid collecting tank 160 is correspondingly arranged below the liquid outlet joint 115, the liquid outlet pipe 140 and the liquid outlet collector 150.

[0099] In some examples, the liquid outlet connector 115 and the liquid outlet pipe 140 can be connected to the first connection. The liquid outlet pipe 140 and the liquid outlet collector 150 can be connected to the second connection. The first collecting tank 160 can be correspondingly arranged below the first connection and the second connection, so that when the refrigerant liquid leaks at the first connection or the second connection, the leaked refrigerant liquid can fall into the first collecting tank 160 below, so that it is convenient for 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.

[0100] In some examples, a liquid leakage sensor may be provided on the surface of the first liquid collecting tank 160 facing the first connection and the second connection. When refrigerant liquid falls into the first liquid collecting tank 160, the liquid leakage sensor may send an indication signal, so that maintenance personnel can check the cause of the leakage in time to reduce the loss of refrigerant liquid.

[0101] In some possible implementations, see Figure 2 and Figure 5As shown, the liquid cooling cabinet 10 further includes an air outlet pipe 170, an air outlet collector 180 and a second liquid collecting tank 190, and the air outlet joint 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 arranged below the air outlet joint 116, the air outlet pipe 170 and the air outlet collector 180.

[0102] 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, so that it is convenient for 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.

[0103] In some examples, a liquid leakage sensor may also 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 check the cause of the leakage in time to reduce the loss of refrigerant liquid.

[0104] In some examples, first sump 160 and second sump 190 may be in communication with each other.

[0105] 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, and 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.

[0106] 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.

[0107] At the same time, the refrigerant liquid can generate gaseous refrigerant after absorbing heat. When the gaseous refrigerant is saturated, the gaseous refrigerant can be introduced into the gas outlet 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.

[0108] In some possible implementations, see Figure 5 As shown, 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 connecting member 121 is located inside the third liquid collecting tank 230.

[0109] The third liquid collecting tank 230 of the embodiment of the present application can be used to contain the refrigerant liquid leaked between the first connector 121 and the second connector 122. This makes it convenient for 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.

[0110] In some examples, the third liquid collecting tank 230 is arranged along the length direction Y. The third liquid collecting tank 230 is arranged corresponding to the liquid inlet pipe 103. Exemplarily, the number of the third liquid collecting tank 230 and the liquid inlet pipe 103 is the same, and both can be set to three.

[0111] 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 time to reduce the loss of the refrigerant liquid.

[0112] In some possible implementations, see Figure 5 and Fig. 9 As shown, the independent compartment 110 includes a strong current outlet 117 and a weak current outlet 118. Along the width direction Z, the strong current outlet 117 and the weak current outlet 118 are respectively arranged on two side walls 1111.

[0113] Along the height direction X, a high-current cable 240 and a low-current cable 250 may be provided on the top of the IT equipment 20. Along the width direction Z, the high-current cable 240 and the low-current 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-current cable 240 may pass through the high-current outlet 117 and be connected to the power distribution management unit 260 of the liquid cooling cabinet 10. The low-current cable 250 may pass through the low-current outlet 118 and pass out of the independent compartment 110.

[0114] In some examples, the high-power cables 240 of multiple IT devices 20 can all be plugged into the power distribution management unit 260 .

[0115] In some examples, the high-voltage outlet 117 and the liquid outlet connector 115 may be disposed on the same side panel 102. Along the height direction X, the height of the high-voltage outlet 117 may be higher than the height of 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 outlet 117 and the liquid outlet connector 115 leaks refrigerant liquid and soaks the high-voltage cable 240.

[0116] In some examples, the low-voltage outlet 118 and the air outlet connector 116 may be disposed on the same side panel 102 .

[0117] 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 a plurality of weak current cables 250 led out of a plurality of independent compartments 110. The weak current cable management trough may be provided corresponding to the weak current cable outlet 118.

[0118] In some possible implementations, see Fig.10 As shown, the liquid cooling cabinet 10 of the present application may be equipped with a liquid cooling distribution unit 30 (Coolant Distribution Unit, CDU). The liquid cooling distribution unit 30 may adjust the temperature of the refrigerant liquid. The liquid cooling distribution unit 30 may be arranged side by side with the liquid cooling cabinet 10. The liquid cooling distribution unit 30 may include a heat exchanger 310 and a gas collecting container 320.

[0119] In some examples, one end of the heat exchanger 310 may be connected to the liquid outlet 210, and the other end may be connected to the liquid inlet 200. The high-temperature refrigerant liquid flowing out of the liquid outlet 210 may be converted into a low-temperature refrigerant liquid after passing through the heat exchanger 310, and may flow into the independent compartment 110 again through the liquid inlet 200 to cool the IT equipment 20, and may be circulated in sequence.

[0120] 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.

[0121] In some examples, the gas collecting container 320 has a sealed space. The gas collecting container 320 can be connected to the gas extraction interface 220. The gas collecting container 320 can be used to collect gaseous refrigerant to centrally process the gaseous refrigerant, thereby reducing the possibility of gaseous refrigerant volatilizing to the outside air, causing environmental pollution or affecting the health of maintenance personnel.

[0122] 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 .
