After the liquid cooling heat exchange unit is used for a period of time, the liquid cooling heat exchange unit needs to be maintained. In the related art, the liquid cooling heat exchange unit is usually designed to be pullable, and the liquid cooling heat exchange unit needs to be pulled out to be maintained, which leads to that the traditional liquid cooling heat exchange unit is powered off, and further leads to that the traditional liquid cooling heat exchange unit has the problem of not being convenient for online maintenance, and also has a great impact on the server operation.

[0052] Based on this, the application designs a liquid cooling heat exchange unit, which can realize online maintenance without affecting the continuous operation of the server.

[0053] Figure 1 The structure of the liquid cooling heat exchange unit in the embodiment of the application is shown, Figure 2 The structure of the power supply, the pull box, and the locking mechanism in the embodiment of the application is shown.

[0054] Please refer to Figure 1 and Figure 2 The embodiment of the application provides a liquid cooling heat exchange unit 10, which is arranged on a cabinet 20. The cabinet 20 is provided with a socket (not shown in the figure), and the liquid cooling heat exchange unit 10 can be installed on the cabinet 20 and is convenient for the liquid cooling heat exchange unit 10 to take power through the socket on the cabinet 20.

[0055] The liquid cooling heat exchange unit 10 includes a case 100, a power supply 200, and a pull box 300. The case 100 is configured to be operable to move relative to the cabinet 20 along a first direction F1. Specifically, the cabinet 20 is provided with a receiving groove, and the case 100 is configured to be operable to move along the first direction F1 to push into or exit the receiving groove. The case 100 can be pulled out to move along the first direction F1, so that the case 100 exits the receiving groove. The case 100 can also be pushed to move along the first direction F1, so that the case 100 pushes into the receiving groove.

[0056] The power supply 200 comprises a power supply body 210 and a power supply line 220 arranged in the cabinet 100, and a power supply plug 230 matched with the socket, the power supply body 210 is electrically connected with the power supply plug 230 through the power supply line 220, the power supply plug 230 is arranged along the first direction F1 in the cabinet 100 and protrudes from a side surface of the cabinet 100 along the first direction F1 to be plugged into the socket.

[0057] Specifically, the cabinet 100 has a receiving space R, the cabinet 100 is provided with a socket (not shown in the figure) through which the power supply plug 230 passes, the power supply plug 230 can extend out of the socket along the first direction F1 to protrude from a side surface of the cabinet 100 along the first direction F1 and be plugged into the socket.

[0058] In this way, the power supply plug 230 can be plugged into the socket on the cabinet 20 during the process of pushing the cabinet 100 into the receiving groove along the first direction F1.

[0059] The pull box 300 is arranged on the inner wall of the cabinet 100 and located in the cabinet 100. The pull box 300 is configured to be driven to elongate the power supply line 220 along the first direction F1 under the action of the driving force for driving the cabinet 100 to move along the first direction F1.

[0060] In this way, when the cabinet 100 is used, the cabinet 100 can be moved along the first direction F1 towards the side close to the socket, so that the cabinet 100 is pushed into the receiving groove, and the power supply plug 230 can be plugged into the socket on the cabinet 20. When it is necessary to maintain the components in the cabinet 100, the cabinet 100 can be moved along the first direction F1 away from the socket by an external force, so that the pull box 300 can be driven to elongate the power supply line 220 along the first direction F1 under the action of the external force, so that the power supply plug 230 can continue to be plugged into the socket, so that the liquid cooling heat exchange unit 10 can continue to be powered by the power supply 200, so that the liquid cooling heat exchange unit 10 can be maintained online without affecting the continuous operation of the server.

[0061] In some embodiments, referring to Figure 1 and Figure 2 , and referring to Figure 3 , the pull box 300 comprises a winding drum 310 and a winding spring 320, the power supply line 220 is wound on the winding drum 310, one end of the power supply line 220 is electrically connected with the power supply body 210, the other end of the power supply line 220 is electrically connected with the power supply plug 230, the inner side of the winding spring 320 is connected with the inner wall of the cabinet 100 along the winding direction of the winding spring 320, and the outer side of the winding spring 320 is connected with the winding drum 310.

[0062] Specifically, the coil spring 320 is installed on the inner side wall of the cabinet 100 through the mounting seat 330.

[0063] Specifically, the power line 220 is provided with two, one of which is electrically connected to the positive pole of the power body 210 and the power plug 230 respectively, and the other is electrically connected to the negative pole of the power body 210 and the power plug 230 respectively.

[0064] The two power lines 220 are wound on the reel 310, so that the two power lines 220 can be elongated in the first direction F1.

[0065] In this way, during the movement of the cabinet 100 driven by an external force along the first direction F1 away from the socket side, the reel 310 can rotate under the driving of the external force, thereby driving the power line 220 to be elongated in the first direction F1, thereby realizing online maintenance of the liquid cooling heat exchange unit 10 under continuous power supply, and the coil spring 320 can be elastically deformed. After completing the online maintenance, during the movement of the cabinet 100 pushed along the first direction F1 towards the socket side, the reel 310 can be reversely rotated under the elastic recovery of the coil spring 320, and the automatic winding of the power line 220 can be realized, so as to realize the elongation of the power line 220 in the first direction F1 thereafter.

[0066] In some embodiments, referring to Figure 2 The liquid cooling heat exchange unit 10 further comprises a locking mechanism 400 for limiting the movement of the power plug 230 along the first direction F1 away from the socket side.

[0067] In this way, after the power plug 230 is plugged into the socket, the movement of the power plug 230 along the first direction F1 away from the socket side can be limited by the locking mechanism 400, and when the components in the cabinet 100 need to be maintained and the cabinet 100 is moved along the first direction F1 away from the socket side by an external force, the possibility of separation of the power plug 230 and the socket under the external force can be reduced, thereby improving the reliability of online maintenance.

[0068] In some embodiments, the locking mechanism 400 comprises a first connecting seat 410 and a locking piece 420, the first connecting seat 410 is connected with the power plug 230, and the first connecting seat 410 is detachably connected with the cabinet 20 through the locking piece 420.

[0069] Specifically, the locking member 420 is a locking bolt, and the locking mechanism 400 further comprises a second connecting seat 430 arranged on the cabinet 20, the first connecting seat 410 and the second connecting seat 430 are respectively provided with threaded holes matched with the locking member 420, so that the locking member 420 is screwed into the threaded holes on the first connecting seat 410 and the second connecting seat 430, so that the first connecting seat 410 is detachably connected with the cabinet 20 through the locking member 420, and the movement of the power plug 230 along the first direction F1 away from the socket can be limited by the locking mechanism 400 after the power plug 230 is plugged into the socket.

[0070] Optionally, the liquid cooling heat exchange unit 10 further comprises a plug cover 240 arranged on the side of the cabinet 100 close to the cabinet 20 along the first direction F1, and the end of the power plug 230 penetrating out of the cabinet 100 along the first direction F1 is arranged in the plug cover 240 to be plugged into the socket on the cabinet 20.

[0071] In some embodiments, referring to Figure 1 , and referring to Figure 4 and Figure 5 , the liquid cooling heat exchange unit 10 further comprises a heat exchanger 510, the heat exchanger 510 has a first heat exchange channel (not shown in the figure) and a second heat exchange channel (not shown in the figure) capable of exchanging heat with the first heat exchange channel, and the cabinet 100 is provided with a primary liquid inlet 101, a primary liquid outlet 102, a secondary liquid supply port 103 and a secondary liquid return port 104. The primary liquid inlet 101 and the secondary liquid supply port 103 are respectively communicated with the two ends of the first heat exchange channel, and the secondary liquid return port 104 and the primary liquid outlet 102 are respectively communicated with the two ends of the second heat exchange channel.

[0072] The primary side is the cold source side, and the primary side is provided with a cold source (such as a refrigeration device), the secondary side is the cabinet side or the server side, and the secondary side is provided with the cabinet 20, and the server includes the cabinet 20.

[0073] Thus, the cooling liquid of the primary side can flow into the first heat exchange channel through the primary liquid inlet 101, and then flow to the cabinet 20 of the secondary side through the secondary liquid supply port 103 to cool the cabinet 20. The cooling liquid after cooling can flow into the second heat exchange channel through the secondary liquid return port 104, and then flow to the refrigeration equipment of the primary side through the primary liquid outlet 102. In this process, the cooling liquid in the first heat exchange channel can exchange heat with the cooling liquid in the second heat exchange channel, and the heat exchanger 510 can be used to realize the heat exchange between the primary side and the secondary side, so that the liquid cooling heat exchange unit 10 can be used to cool the cabinet 20.

[0074] In some embodiments, the liquid cooling heat exchange unit 10 further comprises elastic pipes (not shown in the figure), and the primary liquid inlet 101, the secondary liquid supply port 103, the secondary liquid return port 104, and the primary liquid outlet 102 are respectively provided with the elastic pipes.

[0075] Specifically, the elastic pipe is a rubber hose, and the elastic pipe has a length surplus so as to pull out the cabinet 100 without water.

[0076] Taking the secondary liquid supply port 103 as an example, the secondary liquid supply port 103 is communicated with the cooling liquid channel of the cabinet 20 through an elastic pipe, and online maintenance can be realized without water during the process of pulling out the cabinet 100.

[0077] In some embodiments, the liquid cooling heat exchange unit 10 further comprises a circulating pump 520, a liquid supply pipeline 530, a liquid return pipeline 540, a bypass pipeline 550, and a bypass valve 551. The first heat exchange channel is communicated with the secondary liquid supply port 103 through the liquid supply pipeline 530, the secondary liquid return port 104 is communicated with the second heat exchange channel through the liquid return pipeline 540, the circulating pump 520 is arranged on the liquid supply pipeline 530, the bypass pipeline 550 is communicated with the liquid supply pipeline 530 and the liquid return pipeline 540 respectively, and the bypass valve 551 is arranged on the bypass pipeline 550.

[0079] Optionally, the connection between the liquid supply pipeline 530 and the bypass pipeline 550 is located on the downstream side of the outlet of the circulating pump 520.

[0080] The cooling liquid of the primary side can flow into the cooling liquid channel of the cabinet 20 of the secondary side through the primary liquid inlet 101, the first heat exchange channel and the secondary liquid supply port 103 to cool the cabinet 20, and the cooling liquid after cooling can flow to the refrigeration equipment of the primary side through the secondary liquid return port 104, the second heat exchange channel and the primary liquid outlet 102, so that the circulating pump 520 and the heat exchanger 510 can realize the circulating heat exchange between the primary side and the secondary side. Since the bypass pipeline 550 is connected with the liquid supply pipeline 530 and the liquid return pipeline 540 respectively, the bypass valve 551 on the bypass pipeline 550 can be opened according to the need, the circulating pump 520 is protected, and dry running of the circulating pump 520 is avoided.

[0081] In some embodiments, the circulating pump 520 has an inlet and an outlet, the liquid supply pipeline 530 includes a first liquid supply section 531 and a second liquid supply section 532, the inlet is connected with the first heat exchange channel through the first liquid supply section 531, the outlet is connected with the secondary liquid supply port 103 through the second liquid supply section 532, a first chuck is arranged at the inlet of the circulating pump 520, a second chuck is arranged on the first liquid supply section 531 and detachably connected with the first chuck, and a third chuck is arranged at the outlet of the circulating pump 520, and a fourth chuck is arranged on the second liquid supply section 532 and detachably connected with the third chuck.

[0082] Optionally, the first liquid supply section 531 is provided with an inlet valve 533, and the second liquid supply section 532 is provided with an outlet valve 534. Specifically, the inlet valve 533 and the outlet valve 534 are both ball valves.

[0083] Optionally, the first chuck, the second chuck, the third chuck and the fourth chuck are all quick chucks.

[0084] Since the inlet and the outlet of the circulating pump 520 are connected by chucks (quick chucks), the circulating pump 520 is convenient to replace, and the inlet valve 533 and the outlet valve 534 can be closed under the condition that the liquid cooling heat exchange unit 10 does not stop, so that another circulating pump 520 can be replaced online when one circulating pump 520 is running.

[0085] In some embodiments, a primary side adjusting valve 560 is arranged on the pipeline between the primary liquid inlet 101 and the first heat exchange channel. The flow of the cooling liquid flowing into the secondary liquid supply port 103 can be adjusted through the primary side adjusting valve 560, and then the liquid supply temperature of the secondary side can be adjusted.

[0086] Optionally, a secondary side flow meter 580 is arranged on the pipeline between the secondary liquid supply port 103 and the first heat exchange channel, that is, the secondary side flow meter 580 is arranged on the liquid supply pipeline 530, so that the flow of the cooling liquid flowing into the secondary liquid supply port 103 can be adjusted through the secondary side flow meter 580, and then the liquid supply temperature of the secondary side can be adjusted.

[0087] In some embodiments, the liquid cooling heat exchange unit 10 further comprises a liquid supplement pipeline 571, a liquid supplement pump 572 and a liquid storage tank 573. The liquid supplement pipeline 571 is arranged in parallel with the liquid supply pipeline 530 and communicates between the first heat exchange channel and the secondary liquid supply port 103. The liquid supplement pump 572 and the liquid storage tank 573 are arranged on the liquid supplement pipeline 571. An inner top wall of the liquid storage tank 573 is provided with an ultraviolet lamp 574.

[0088] Optionally, the ultraviolet lamp 574 is embedded on a top plate of the liquid storage tank 573. The ultraviolet lamp 574 can be turned on according to a time period set by a program. For example, the ultraviolet lamp 574 is electrically connected to the controller 600. The controller 600 is used to adjust the start-stop period of the ultraviolet lamp 574, set the start-stop period of the ultraviolet lamp 574 according to the program, and then irradiate and sterilize the cooling liquid in the liquid storage tank 573. The ultraviolet lamp 574 can also be manually set to be turned on and off. For example, the control screen and the ultraviolet lamp 574 are respectively electrically connected to the controller 600. The ultraviolet lamp 574 is turned on by operating the control screen, and then irradiation and sterilization are performed.

[0089] The liquid supply pipeline 530 can be supplemented according to needs, thereby realizing the liquid supplement function of the secondary liquid supply port 103. Specifically, the liquid supply pipeline 530 is provided with a pressure gauge 575. The pressure of the liquid flowing into the secondary liquid supply port 103 is detected by the pressure gauge 575. If the pressure is small, it is likely that the water pressure at the cabinet 20 on the secondary side is too low. At this time, the liquid supplement pump 572 can be started to suck water from the liquid storage tank 573 and supplement into the cooling liquid channel of the secondary liquid supply port 103 and the cabinet 20, thereby realizing online liquid supplement of the cabinet 20.

[0090] In addition, the liquid storage tank 573 is provided with the ultraviolet lamp 574. The ultraviolet light emitted by the ultraviolet lamp 574 can be used to sterilize the cooling liquid in the liquid storage tank 573.
