Description

TECHNICAL FIELD

[0002] At present, as a specific equipment network of global cooperation, the operation stability of the data center cabinet of the data center is crucial, and one of the core reasons affecting the operation stability of the data center cabinet is the operation temperature of the data center cabinet. In order to improve the operation stability of the data center cabinet, the staff will set up a corresponding cooling system to cool the data center cabinet in time and reliably. In fact, the heat dissipation system for the data center cabinet mainly includes liquid cooling and air cooling. Among them, the liquid cooling system using cooling medium as intermediate heat transfer medium has higher heat dissipation reliability and higher heat dissipation power, and has become the most widely used cooling system in the prior art.

[0003] In the prior art, the liquid cooling system uses a large number of liquid delivery pipelines to form a circulating path of the cooling medium, and the staff needs to regularly maintain and repair some special positions (such as the upstream and downstream of the heat exchange device and the upstream and downstream of the pump body) of the liquid delivery pipeline to eliminate the risk of failure and improve the operation stability of the liquid cooling system.

[0004] However, although the staff will close the valve, manually hold the pipeline and adjust the posture of the pipeline during maintenance and repair to prevent the cooling medium from flowing out of the maintenance and repair position. However, after the valve is closed, a large amount of cooling medium will still remain in the pipeline. The above operation not only still has the possibility of cooling medium leakage and spilling, but also affects the maintenance and repair efficiency and difficulty of the staff. SUMMARY

[0042] In order to solve the problem of difficult maintenance of the liquid cooling communication pipeline of the liquid cooling system for data center in the prior art, the present application provides a communication device and a cooling system having the same.

[0043] As shown in Figures 1 to 8 The communication device includes a first communication structure 10, a second communication structure 20 and a plugging structure 30. The first communication structure 10 has a first opening 11, a liquid passing cavity 12 and a first liquid passing hole 13. The first liquid passing hole 13 communicates with the first opening 11 through the liquid passing cavity 12. The second communication structure 20 has a second opening 21, a liquid storage cavity 22 and a second liquid passing hole 23. The second liquid passing hole 23 communicates with the second opening 21 through the liquid storage cavity 22. The first communication structure 10 is detachably installed at the second opening 21, and the first opening 11 is located below the second opening 21. The plugging structure 30 is movably arranged in the liquid passing cavity 12. The plugging structure 30 has an avoiding position for avoiding at least part of the first opening 11 and a plugging position for plugging the first opening 11. When the first communication structure 10 is installed on the second communication structure 20 and the plugging structure 30 is in the avoiding position, the liquid passing cavity 12 communicates with the liquid storage cavity 22 through the first opening 11 and the second opening 21 to form a communication cavity. When the second communication structure 20 is detached from the first communication structure 10, the liquid storage cavity 22 stores part of the liquid in the communication cavity, and the plugging structure 30 is in the plugging position to store another part of the liquid in the communication cavity through the plugging structure 30 and the liquid passing cavity 12.

[0044] The first communication structure 10 of the communication device has a first opening 11, a liquid passing cavity 12 and a first liquid passing hole 13, the first liquid passing hole 13 is communicated with the first opening 11 through the liquid passing cavity 12, the second communication structure 20 has a second opening 21, a liquid storage cavity 22 and a second liquid passing hole 23, the second liquid passing hole 23 is communicated with the second opening 21 through the liquid storage cavity 22, the first communication structure 10 is detachably installed at the second opening 21, the first opening 11 is located below the second opening 21, the blocking structure 30 is movably arranged in the liquid passing cavity 12, the blocking structure 30 has an avoiding position for avoiding at least part of the first opening 11 and a blocking position for blocking the first opening 11. When the first communication structure 10 is installed on the second communication structure 20 and the blocking structure 30 is in the avoiding position, the liquid passing cavity 12 is communicated with the liquid storage cavity 22 through the first opening 11 and the second opening 21 to form a communication cavity; when the second communication structure 20 is detached from the first communication structure 10, the liquid storage cavity 22 stores part of the liquid in the communication cavity, and the blocking structure 30 is in the blocking position to store another part of the liquid in the communication cavity through the blocking structure 30 and the liquid passing cavity 12. In this way, in the cooling system using the communication device in the embodiment to communicate two adjacent pipelines at a specific position, when the staff needs to be overhauled, the blocking structure 30 can be operated to move to the blocking position, and then the first communication structure 10 is detached. Since the first opening 11 is located below the second opening 21, during the detachment of the first communication structure 10, the liquid storage cavity 22 will store part of the liquid in the communication cavity (without leakage), and the blocking structure 30 and the liquid passing cavity 12 will store another part of the liquid in the communication cavity (without leakage), thereby completely avoiding the possibility of liquid leakage, omitting the operation of the staff adjusting the posture of the pipeline, greatly reducing the difficulty of the staff's overhaul, and thereby solving the problem of large overhaul difficulty of the liquid cooling communication pipeline of the liquid cooling system for the data center in the prior art. At the same time, when the first communication structure 10 and the second communication structure 20 are assembled together and the blocking structure 30 is in the avoiding position, the liquid passing cavity 12 can be communicated with the liquid storage cavity 22 through the first opening 11 and the second opening 21 to realize the normal flow of the liquid and ensure that the cooling system can operate normally.

[0045] In the embodiment, the first communication structure 10 and the second communication structure 20 are arranged along the vertical height direction, and most of the second communication structure 20 is located below the first communication structure 10, so as to ensure that the liquid storage cavity 22 has high liquid storage reliability.

[0046] In the embodiment, the communication device further comprises a seat body 1, and the second communication structure 20 is arranged on the seat body 1 to fix the second communication structure 20, thereby further improving the liquid storage stability of the second communication structure 20.

[0047] As Figures 1 to 6As shown, the communication device further comprises a driving structure 40, the first communication structure 10 further has a first mounting hole 14 in communication with the liquid passing cavity 12, at least part of the driving structure 40 extends into the communication cavity through the first mounting hole 14 to be in driving connection with the blocking structure 30, and the driving structure 40 is used to drive the blocking structure 30 to move between the avoiding position and the blocking position. In this way, the worker can adjust the position of the blocking structure 30 in the liquid passing cavity 12 through the driving structure 40, thereby reducing the operation difficulty of the worker and realizing the position switching of the blocking structure 30.

[0048] As shown in the drawings, Figures 1 to 6 The inner wall of the first mounting hole 14 is provided with a first threaded portion, the driving structure 40 comprises a rod-shaped driving member 41 and an operating member 42, at least part of the rod-shaped driving member 41 is arranged in the first mounting hole 14, one end of the rod-shaped driving member 41 is located in the liquid passing cavity 12 to be in driving connection with the blocking structure 30, and the other end of the rod-shaped driving member 41 is located outside the liquid passing cavity 12; wherein the outer circumferential surface of the rod-shaped driving member 41 is provided with a second threaded portion, and the second threaded portion is in threaded connection with the first threaded portion. The operating member 42 is arranged on the end of the rod-shaped driving member 41 located outside the liquid passing cavity 12, and the operating member 42 is used to drive the rod-shaped driving member 41 to rotate. In this way, the worker can drive the rod-shaped driving member 41 to rotate by manually operating the operating member 42 to rotate, and then drive the blocking structure 30 to move, thereby reducing the operation difficulty of the worker, and also making the structure of the driving structure 40 simpler, reducing the processing difficulty of the worker and the processing cost of the driving structure 40.

[0049] In the embodiment, the operating member 42 comprises a connecting plate arranged on the end of the rod-shaped driving member 41 located outside the liquid passing cavity 12 and a plurality of rod-shaped handles arranged around the connecting plate, and the worker can hold the handles to drive the operating member 42 to rotate, and then drive the rod-shaped driving member 41 to rotate.

[0050] In the embodiment, a connecting column is arranged on the end of the rod-shaped driving member 41 located outside the liquid passing cavity 12, and the connecting plate is arranged on the connecting column, and the fastener 43 is fastened on the connecting column to realize the connection between the operating member 42 and the rod-shaped driving member 41.

[0051] Alternatively, a rotatable ring can be arranged on the end of the rod-shaped handle away from the connecting plate. In this way, when the worker's limbs accidentally touch the rod-shaped handle, the rotatable ring can reduce the friction and guide the transmission direction of the force to avoid the possibility of the worker accidentally rotating the operating member 42.

[0052] As shown in the drawings, Figures 1 to 6As shown, the first communication structure 10 comprises a cover structure 15 and a first tubular structure 17 arranged on the cover structure 15, the cover structure 15 has a first opening 11 and a liquid passing cavity 12, and the first tubular structure 17 is in communication with the liquid passing cavity 12 to form a first liquid passing hole 13 through an end of the first tubular structure 17 away from the cover structure 15. At least part of the cover structure 15 is located in the liquid storage cavity 22, and the cover structure 15 is detachably connected with the second communication structure 20; wherein at least part of the first tubular structure 17 is made of flexible material. In this way, since the first tubular structure 17 is a flexible tube, the position of the detached cover structure 15 can be adjusted by the worker (such as placed on a maintenance trolley) to facilitate the subsequent maintenance operation of the worker.

[0053] As shown, Figures 1 to 6 the second communication structure 20 comprises a storage shell 25 and a second tubular structure 26 in communication with the storage shell 25, the storage shell 25 has a second opening 21 and a liquid storage cavity 22, and the second tubular structure 26 forms a second liquid passing hole 23 at an end away from the storage shell 25.

[0054] In this embodiment, the storage shell 25 is a cylindrical shell to realize the storage of liquid.

[0055] As shown, Figures 1 to 6 the inner cavity of the cover structure 15 forms the liquid passing cavity 12, and in the direction from the second communication structure 20 to the first communication structure 10, the liquid passing cavity 12 comprises a first sub-cavity 121, a second sub-cavity 122 and a third sub-cavity 123 which are sequentially communicated, the connection between the first sub-cavity 121 and the second sub-cavity 122 is the first opening 11, the radial dimension of the second sub-cavity 122 is smaller than that of the first sub-cavity 121 to form an annular limiting surface 18 at the first opening 11, and the radial dimension of the third sub-cavity 123 gradually decreases. Wherein, the plugging structure 30 is movably arranged in the first sub-cavity 121, and there is a first gap 191 between the cavity wall of the first sub-cavity 121 and the outer circumferential surface of the plugging structure 30, when the plugging structure 30 is in the plugging position, the plugging structure 30 abuts against the annular limiting surface 18 to plug the first opening 11, and when the plugging structure 30 is in the avoiding position, the plugging structure 30 is separated from the annular limiting surface 18 to form a second gap 192, and the first opening 11 is in communication with the liquid storage cavity 22 through the second gap 192 and the first gap 191. In this way, the above arrangement on the one hand ensures that when the plugging structure 30 is in the avoiding position, the first opening 11 can be in communication with the liquid storage cavity 22 through the second gap 192 and the first gap 191 to realize the normal work of the cooling system; on the other hand, it ensures that the plugging structure 30 in the plugging position can realize the plugging operation of the first opening 11 through the abutment with the annular limiting surface 18, thereby improving the plugging reliability of the plugging structure 30.

[0056] Specifically, when the blocking structure 30 and the annular limiting surface 18 abut against each other, a sealed cavity is formed between the second sub-cavity 122, the third sub-cavity 123, the first tubular structure 17, and the liquid equipment in communication with the first tubular structure 17, so as to avoid liquid leakage. Meanwhile, since the first opening 11 is located below the second opening 21, the liquid in the first sub-cavity 121 can flow into the liquid storage cavity 22 for storage during the dismounting of the cover-shaped structure 15, thereby completely avoiding the possibility of liquid leakage.

[0057] As shown in Figures 1 to 8 The connecting structure 50 is drivingly connected with the driving structure 40, and the driving structure 40 drives the connecting structure 50 to rotate. In this way, during the driving of the driving structure 40 to move the blocking structure 30, the connecting structure 50 can also be synchronously driven to rotate. With the rotation of the connecting structure 50, the operator only needs to operate the cover-shaped structure 15 to stop rotating, so as to realize the dismounting between the cover-shaped structure 15 and the connecting structure 50, that is, to dismount the cover-shaped structure 15 from the second connecting structure, thereby reducing the operation difficulty of the operator.

[0058] In the embodiment, the connecting structure 50 has a matching protrusion 51, and the rod-shaped driving member 41 is provided with a matching recess 411, the matching protrusion extends into the matching recess 411 and can slide along the extension direction of the matching recess 411. The inner wall of the matching recess 411 and the outer peripheral surface of the matching protrusion 51 are stopper-fitted, so as to drive the connecting structure 50 to rotate through the rod-shaped driving member 41. In this way, through the cooperation between the matching recess 411 and the matching protrusion 51, on the one hand, the rod-shaped driving member 41 can drive the connecting structure 50 to rotate, and on the other hand, the relative sliding between the rod-shaped driving member 41 and the connecting structure 50 in the height direction can be realized, so as to ensure that the cover-shaped structure 15 can be stably dismounted from the second connecting structure 20.

[0059] In the embodiment, the matching protrusion 51 is a quadrangular prism structure, and the matching recess 411 is matched with the outer peripheral surface of the matching protrusion 51.

[0060] It should be noted that the structure of the matching protrusion 51 is not limited to this, and can be adjusted according to the working conditions and use requirements.

[0061] In the embodiment, the blocking structure 30 comprises a plate-shaped support body 31 and a sealing member 32, the plate-shaped support body 31 is arranged on the end of the rod-shaped driving member 41 located in the liquid passing cavity 12, the plate-shaped support body 31 has a hole communicating with the matching recess 411, and the hole is used for the matching protrusion 51 to extend into the matching recess 411. The sealing member 32 is arranged on the plate surface of the plate-shaped support body 31 away from the liquid storage cavity 22, and the sealing member 32 is used for abutting against the annular limiting surface 18. At least part of the sealing member 32 is made of elastic material. In this way, the sealing member 32 made of flexible material can elastically deform in the process of abutting against the annular limiting surface 18, so that the blocking structure 30 can be more closely fitted with the annular limiting surface 18, thereby improving the blocking reliability of the blocking structure 30. At the same time, the plate-shaped support body 31 can support the sealing member 32 with soft texture and stably provide pressure to the sealing member 32, further improving the sealing reliability of the blocking structure 30.

[0062] In the embodiment, part of the annular limiting surface 18 is an inclined surface, so as to form a conical structure with gradually decreasing inner diameter in the direction from the second communication structure 20 to the first communication structure 10. In this way, the above-mentioned arrangement helps to promote the elastic deformation of the sealing member 32 supported by the flexible material, further improving the blocking reliability of the blocking structure 30.

[0063] As shown in Figures 1 to 6 The cover-shaped structure 15 has a first guide portion 16, and the second communication structure 20 has a second guide portion 24, one of the first guide portion 16 and the second guide portion 24 is a protrusion, and the other of the first guide portion 16 and the second guide portion 24 is a recess, the protrusion extends into the recess and can slide along the extension direction of the recess. The recess extends in the height direction of the communication device to stop the rotation of the cover-shaped structure 15. In this way, in the process that the driving structure 40 drives the connecting structure 50 to rotate, through the cooperation between the first guide portion 16 and the second guide portion 24, on the one hand, the rotation of the cover-shaped structure 15 can be stopped, so that the cover-shaped structure 15 can spontaneously separate from the connecting structure 50 under the thread cooperation with the connecting structure 50, to realize the disassembly of the cover-shaped structure 15; on the other hand, the movement direction of the cover-shaped structure 15 can be guided and fixed, so as to facilitate the worker to take the disassembled cover-shaped structure 15.

[0064] As shown in Figures 1 to 8As shown, the connecting structure 50 comprises a ring-shaped main body 52 and a support frame 53, the ring-shaped main body 52 is rotatably arranged on the inner wall of the liquid storage cavity 22 and sleeved on the cover-shaped structure 15, the support frame 53 is arranged in the inner hole of the ring-shaped main body 52, and the matching convex part 51 is arranged on the support frame 53. Among them, the through hole of the support frame 53 forms a communication hole 531. In this way, the matching convex part 51 is supported through the support frame 53, and at the same time, the through hole of the support frame 53 forms a communication hole 531, so as to ensure that the liquid can flow normally. At the same time, the above arrangement also makes the structure of the connecting structure 50 more simple, easy to process and realize, thereby reducing the processing difficulty and processing cost of the connecting structure 50.

[0065] In the embodiment, the support frame 53 comprises a ring-shaped frame and a cross-shaped frame arranged in the ring-shaped frame, the ring-shaped frame is arranged in the ring-shaped main body 52, and the outer surface thereof is attached to the inner wall of the ring-shaped main body 52, and the cross-shaped frame is arranged in the ring-shaped frame, and the matching convex part 51 is arranged at the center position of the cross-shaped frame, so as to support the matching convex part 51 well through the cross-shaped frame.

[0066] In the embodiment, the part of the cover-shaped structure 15 extending into the liquid storage cavity 22 is actually a threaded cylinder, and the inner wall of the ring-shaped main body 52 is provided with a corresponding threaded structure to realize the threaded connection between the cover-shaped structure 15 and the connecting structure 50.

[0067] In the embodiment, a stepped structure is arranged on the outer circumferential surface of the part of the cover-shaped structure 15 located in the liquid storage cavity 22, and the stop surface 151 of the stepped structure is used for limiting and stopping the upper surface of the ring-shaped main body 52 to position the mounting position of the cover-shaped structure 15.

[0068] In the embodiment, the edge of the threaded cylinder is chamfered, and after the threaded cylinder extends into the ring-shaped main body 52, the chamfered part forms a mounting space between the inner wall of the ring-shaped main body 52 and the upper surface of the ring-shaped frame, and the mounting space is used for mounting the sealing structure 70 to realize the sealing operation.

[0069] Optionally, the sealing structure 70 is a sealing ring.

[0070] It should be noted that the communication device in the embodiment actually has a large number of sealing measures, such as mechanical sealing between the mounting cylinder 62, the driving rod 64 and the second mounting hole of the second communication structure 20; for example, the rod-shaped driving member 41 and the first mounting hole 14 are also mechanically sealed, which will not be described here.

[0071] In the embodiment, the length of the first threaded section of the cover-shaped structure 15 for threaded connection with the connecting structure 50 (i.e. the distance when the installed cover-shaped structure 15 is moved to be disassembled) is consistent with the distance of the blocking structure 30 moving from the avoiding position to the blocking position, and the number of turns of the cover-shaped structure 15 when disassembled from the connecting structure 50 is consistent with the number of turns of the rod-shaped driving member 41 when the blocking structure 30 moves from the avoiding position to the blocking position, so that the cover-shaped structure 15 is just disengaged from the connecting structure 50 and the blocking structure 30 is just in the blocking position after the operator operates the operating member 42 to rotate a preset number of turns.

[0072] In the embodiment, the depth of the matching recess 411 and the length of the matching protrusion 51 need to satisfy: greater than the sum of the distance value of the blocking structure 30 moving from the avoiding position to the blocking position and the distance value of the installed cover-shaped structure 15 moving to be disassembled, so as to ensure that the depth of the matching recess 411 and the length of the matching protrusion 51 can be stably matched during the disassembly of the cover-shaped structure 15.

[0073] As shown in Figures 1 to 8 The outer circumferential surface of the annular body 52 is provided with an annular limiting recess 521, and the second connecting structure 20 further has a second mounting hole in communication with the liquid storage cavity 22. The connecting device further comprises a limiting structure 60 provided at the second mounting hole, and the limiting structure 60 has an activatable limiting portion 61. The limiting portion 61 has a limiting position and a disassembly position. When the limiting portion 61 is in the limiting position, the limiting portion 61 extends into the annular limiting recess 521 to limit and stop against the inner wall of the annular limiting recess 521. When the limiting portion 61 is in the disassembly position, the limiting portion 61 exits from the annular limiting recess 521. In this way, the above-mentioned arrangement can realize the fixation and disassembly of the connecting structure 50 through the cooperation between the limiting portion 61 and the annular limiting recess 521, i.e. the operator can easily realize the disassembly and installation of the connecting structure 50 by operating the limiting portion 61. On the other hand, the arrangement of the annular limiting recess 521 can ensure that the connecting structure 50 can rotate, i.e. the limiting portion 61 can only limit the connecting structure 50 in the height direction, and in the circumferential direction of the connecting structure 50, the limiting portion 61 can slide along the annular limiting recess 521, thereby realizing the disassembly of the cover-shaped structure 15.

[0074] As shown in Figures 1 to 8As shown, the limiting part 61 is in a spherical structure, the limiting structure 60 further comprises a mounting cylinder 62 and a driving rod 64, the mounting cylinder 62 is arranged at the second mounting hole, the mounting cylinder 62 has a mounting cavity and a through hole in communication with the mounting cavity, and the mounting cavity is in communication with the second mounting hole. At least part of the driving rod 64 is arranged in the through hole, and the outer circumferential surface of the driving rod 64 is threadedly connected with the inner wall of the through hole. Among them, the spherical structure is movably arranged in the mounting cavity, and the driving rod 64 is used to push the spherical structure to move between the limiting position and the disassembly position. When the spherical structure is in the limiting position, the spherical structure rolls under the action of the friction force between it and the limiting recess. In this way, the staff can rotate by operating the driving rod 64 to push the limiting part 61 to move to the limiting position by the driving rod 64, so that the operation mode of the staff is more simple. At the same time, the limiting part 61 arranged in the spherical structure can reduce the friction force (sliding friction is changed into rolling friction) between the limiting part 61 and the annular limiting recess 521, thereby improving the rotation smoothness of the connecting structure 50, and also improving the disassembly simplicity of the cover-shaped structure 15.

[0075] In this embodiment, the driving rod 64 is a self-rotating screw.

[0076] Optionally, one end of the self-rotating screw close to the limiting part 61 is a magnetic end to drive the limiting part 61 to move.

[0077] As can be seen, in the communication device in this embodiment, the staff can continue to rotate the operating member 42 to realize the disassembly between the first communication structure 10 and the second communication structure 20 while switching the plugging structure 30 to the plugging position, so as to ensure that there is no liquid leakage problem in the subsequent maintenance process of the staff, greatly reducing the maintenance difficulty of the staff and improving the maintenance efficiency of the staff.

[0078] As Figure 9 shown, the embodiment also provides a cooling system, the cooling system comprises a cooling tower 3, a cooling structure 5, a pump body structure 2 and a heat exchange device 4, the cooling tower 3 is used for storing cooling medium. The cooling structure 5 is arranged on the to-be-cooled member for cooling the to-be-cooled member. At least two communication pipelines 6 are arranged between the cooling tower 3 and the cooling structure 5, at least one communication pipeline 6 is used for flowing the cooling medium in the cooling tower 3 to the cooling structure 5, and at least another communication pipeline 6 is used for flowing the cooling medium in the cooling structure 5 to the cooling tower 3. The pump body structure 2 is arranged on the communication pipeline 6 to drive the cooling medium to flow. The heat exchange device 4 is arranged on the communication pipeline 6 to exchange heat for the cooling medium, wherein the communication pipeline 6 is provided with a communication device, and the communication device is the above-mentioned communication device.

[0079] In this embodiment, the heat exchange device 4 is a plate heat exchanger.

[0080] In the embodiment, the communication pipeline 6 for flowing the cooling medium in the cooling structure 5 to the cooling tower 3 is the first communication pipeline 601, and the communication pipeline 6 for flowing the cooling medium in the cooling tower 3 to the cooling structure 5 is the second communication pipeline 602.

[0081] Specifically, the operation mode of the cooling system is as follows:

[0082] Firstly, the cooling system is started, the pump body structure 2 draws the cooling medium from the cooling tower 3 through the second communication pipeline 602, and the cooling medium enters the plate heat exchanger through the first medium inlet of the plate heat exchanger after flowing through a communication device, the cooling medium exchanges heat with the heat exchange medium in the plate heat exchanger through the plate of the plate heat exchanger, the cooled cooling medium continues to flow, and enters the cooling structure 5 in the machine room after flowing through a communication device, so that the cooling structure 5 in the machine room can cool the data center machine room smoothly, the cooling medium is flowed to the first communication pipeline 601, and the cooled cooling medium is flowed back to the plate heat exchanger through the second medium inlet of the plate heat exchanger after flowing through a communication device, and the cooled cooling medium is finally flowed back to the cooling tower 3 through the first communication pipeline 601 to complete the circulation of the cooling medium.

[0083] The maintenance process of the cooling system in the embodiment is as follows:

[0084] Firstly, the cooling system is closed, the pump body structure 2 stops conveying the cooling medium, then the sealing structure 30 is just in the sealing position by rotating the operating member 42 until the first communication structure 10 and the second communication structure 20 are separated, and the leakage of the cooling medium is effectively avoided.

[0085] From the above description, it can be seen that the above-mentioned embodiments of the present application achieve the following technical effects:

[0086] The first communication structure of the communication device has a first opening, a liquid passing cavity and a first liquid passing hole, the first liquid passing hole communicates with the first opening through the liquid passing cavity; the second communication structure has a second opening, a liquid storage cavity and a second liquid passing hole, the second liquid passing hole communicates with the second opening through the liquid storage cavity; the first communication structure is detachably installed at the second opening, the first opening is below the second opening; the blocking structure is movably arranged in the liquid passing cavity, the blocking structure has an avoiding position for avoiding at least part of the first opening and a blocking position for blocking the first opening. When the first communication structure is installed on the second communication structure and the blocking structure is in the avoiding position, the liquid passing cavity communicates with the liquid storage cavity through the first opening and the second opening to form a communication cavity; when the second communication structure is detached from the first communication structure, the liquid storage cavity stores part of the liquid in the communication cavity, and the blocking structure is in the blocking position to store another part of the liquid in the communication cavity through the blocking structure and the liquid passing cavity. In this way, in the cooling system using the communication device in the application to communicate two adjacent pipelines at a specific position, when the staff needs to be overhauled, the blocking structure can be operated to move to the blocking position, and then the first communication structure is detached. Since the first opening is below the second opening, during the detachment of the first communication structure, the liquid storage cavity will store part of the liquid in the communication cavity (without leakage), and the blocking structure and the liquid passing cavity will store another part of the liquid in the communication cavity (without leakage), thereby completely avoiding the possibility of liquid leakage, omitting the operation of the staff adjusting the posture of the pipeline, greatly reducing the difficulty of the staff's overhaul, and thereby solving the problem of high difficulty of the liquid cooling communication pipeline of the liquid cooling system for data center in the prior art. At the same time, when the first communication structure and the second communication structure are assembled together and the blocking structure is in the avoiding position, the liquid passing cavity can communicate with the liquid storage cavity through the first opening and the second opening to realize the normal flow of the liquid, ensuring that the cooling system can operate normally.
