At the same time, the country has put forward more stringent requirements for the PUE (power usage efficiency) of data centers. Traditional air cooling technology has been unable to meet the needs of modern data centers due to its limitations in cooling efficiency and energy-saving goals. Therefore, liquid cooling technology has attracted much attention due to its excellent thermal conductivity and low energy consumption, among which cold plate liquid cooling technology has gradually occupied a place in the market.

[0059] Please refer to Figure 1 and Figure 2, which is a preferred embodiment of the utility model, the liquid-cooling joint anti-leakage liquid diversion mechanism 10 comprises: an anti-leakage liquid box assembly 100 slidably mounted on a first component 20, comprising a box body 110, the box body 110 is provided with a first joint opening 113 and a second joint opening 114 arranged opposite to each other, a liquid storage cavity 111 is arranged between the first joint opening 113 and the second joint opening 114; a first joint 201 of the first component 20 is penetrated in the first joint opening 113; a second joint 301 of the second component 30 is penetrated in the second joint opening 114; a baffle assembly 200, the baffle assembly 200 is movably arranged in the liquid storage cavity 111; and is arranged to block the first joint opening 113 when the baffle assembly 200 is in a blocking state, and have a gap between the baffle assembly 200 and the first joint opening 113; when the baffle assembly 200 is in an avoidance state, the first joint opening 113 is exposed to avoid the first joint 201.

[0060] For ease of understanding, Figure 3 As shown, this embodiment is explained by taking the first component 20 as a shunt pipe and the second component 30 as a server as an example, and each U position is correspondingly installed with a liquid cooling joint anti-leakage liquid guiding mechanism 10. However, it can be understood that the application scope of the liquid cooling joint anti-leakage liquid guiding mechanism described in the utility model is not limited to the connection between the server and the shunt pipe, but can also be applied to a variety of liquid interface scenarios.

[0061] In one embodiment of the present application, the first component 20 has a first joint 201, and the second component 30 has a second joint 301. The first joint 201 and the second joint 301 are liquid cooling joints. After the first joint 201 and the second joint 301 are connected, the cooling liquid can flow between the first component 20 and the second component 30. In one embodiment of the present application, the first joint 201 is a male connector, and the second joint 301 is a female connector; in another embodiment of the present application, the first joint 201 is a female connector, and the second joint 301 is a male connector.

[0062] Under normal circumstances, the first joint 201 of the shunt pipe can rely on its own function to seal the liquid. However, when it fails, the liquid may splash outward from the first joint 201. The liquid-cooling joint anti-leakage liquid diversion mechanism 10 is installed at the interface between the first joint 201 and the second joint 301, and has the functions of spray prevention, leakage prevention and diversion. In one embodiment of the present application, the liquid-cooling joint anti-leakage liquid diversion mechanism 10 mainly includes a liquid-leakage prevention box assembly 100, a baffle assembly 200 and a diversion assembly 400, wherein the baffle assembly 200 has a spray prevention function; the liquid-leakage prevention box assembly 100 and the diversion assembly 400 have the functions of collecting liquid, leak prevention and diversion. The following is a further detailed introduction to each of the above components.

[0063] In one embodiment of the present application, Figure 4 As shown, the anti-leakage liquid box assembly 100 includes a box body 110 and a box cover 120. The box cover 120 is buckled on the box body 110. The two cooperate with each other to make the anti-leakage liquid box assembly 100 generally box-shaped as a whole.

[0064] like Figure 4 and Figure 5 As shown, the box body 110 is provided with a first joint opening 113 and a second joint opening 114 which are arranged opposite to each other. The first joint opening 113 is provided with a first joint 201, and the shape and size of the first joint opening 113 are adapted to the shape and size of the first joint 201. The second joint opening 114 is provided with a second joint 301, and the shape and size of the second joint opening 114 are adapted to the shape and size of the second joint 301.

[0065] A liquid storage chamber 111 is provided between the first joint port 113 and the second joint port 114. After the first joint 201 and the second joint 301 are connected, the interface between the two is provided in the liquid storage chamber 111. The output end of the liquid storage chamber 111 is connected to the input end of the diversion component 400. In one embodiment of the present application, the liquid storage chamber 111 includes a first sub-liquid storage chamber 1111 and a second sub-liquid storage chamber 1112 which are connected together. In another embodiment of the present application, the liquid storage chamber 111 also includes a third sub-liquid storage chamber 1113, and the first sub-liquid storage chamber 1111, the second sub-liquid storage chamber 1112 and the third sub-liquid storage chamber 1113 are connected together in sequence for collecting and storing a small amount of liquid. For simplicity, the present application only takes the liquid storage chamber 111 including the first sub-liquid storage chamber 1111, the second sub-liquid storage chamber 1112 and the third sub-liquid storage chamber 1113 as an example for detailed description.

[0066] Specifically, the first sub-liquid storage chamber 1111, the second sub-liquid storage chamber 1112 and the third sub-liquid storage chamber 1113 are provided with a first guide port 112 at the bottom of the chamber, so as to connect the three chambers together. The liquid in the third sub-liquid storage chamber 1113 can flow into the second sub-liquid storage chamber 1112 through one first guide port 112, the liquid in the second sub-liquid storage chamber 1112 can flow into the first sub-liquid storage chamber 1111 through another first guide port 112, and the liquid in the first sub-liquid storage chamber 1111 can flow into the guide assembly 400 through another first guide port 112.

[0067] like Figure 4 and Figure 6As shown, the shielding plate assembly 200 is provided in both the first sub-liquid storage chamber 1111 and the third sub-liquid storage chamber 1113. The second sub-liquid storage chamber 1112 is provided with a guide positioning assembly 600, and the distance between the second sub-liquid storage chamber 1112 and the first component 20 is smaller than the distance between the first sub-liquid storage chamber 1111 and the third sub-liquid storage chamber 1113 and the first component 20, that is, a first avoidance position 130 is provided on the outer side of the second sub-liquid storage chamber 1112 close to the first component 20, for avoiding the guide positioning assembly 600.

[0068] The shielding plate assembly 200 mainly includes a shielding plate body 210, and the shielding plate assembly 200 is movably arranged in the liquid storage chamber 111. When the shielding plate body 210 is in a shielding state, it can shield the first joint port 113, and there is a gap between the shielding plate body 210 and the first joint port 113; at this time, the first joint 201 is located outside the first joint port 113 and faces the shielding plate body 210. If the sealing function of the first joint 201 itself fails, the liquid will be directly sprayed onto the shielding plate body 210 through the first joint port 113, and flow into the liquid storage chamber 111 along the gap between the shielding plate body 210 and the first joint port 113 under the action of gravity. When the shielding plate assembly 200 is in an avoidance state, the first joint port 113 is exposed to avoid the first joint 201, so that the first joint 201 can pass through the first joint port 113 and enter the liquid storage chamber 111; at this time, the first joint 201 is connected with the second joint 301, and the interface between the two is located in the liquid storage chamber 111, and the liquid leaked from the interface will gather at the bottom of the liquid storage chamber 111 under the action of gravity.

[0069] Specifically, Figure 2 As shown, the shielding plate assembly 200 is configured to rotate when being pushed by the first joint 201 to open the first joint opening 113 , so that the shielding plate assembly 200 is in an evasive state to avoid the first joint 201 .

[0070] More specifically, if Figure 4-Figure 6 As shown, in one embodiment of the present application, the shielding plate assembly 200 includes a rotating shaft 220 , a rotating shaft boss 230 , a fixing bar 240 , a mounting boss 250 and a rotating shaft mounting hole 260 .

[0071] The bottom and top of the baffle body 210 are fixedly mounted with the rotating shaft 220. The rotating shaft boss 230 and the fixing strip 240 are fixedly arranged at the bottom and top of the liquid storage chamber 111, respectively. There are two mounting bosses 250, both of which are fixedly mounted on the inner wall of the box body 110. One of them is mounted on the side wall where the first joint port 113 is located, and the other is mounted on the side wall where the second joint port 114 is located. The two ends of the fixing strip 240 are fixedly connected to the two mounting bosses 250, for example, the fixing strip 240 is mounted on the mounting boss 250, and then the fixing strip 240 is pressed by the box cover 120. Of course, it can be understood that the fixing strip 240 can also be fixedly arranged on the top of the liquid storage chamber 111 by other means, which will not be elaborated here. The rotating shaft boss 230 and the fixing strip 240 are both provided with a rotating shaft mounting hole 260, the size and shape of the rotating shaft mounting hole 260 are adapted to the rotating shaft 220, and the free ends of the two rotating shafts 220 are rotatably inserted into the rotating shaft mounting holes 260 of the rotating shaft boss 230 and the fixing strip 240, respectively, so that the shielding plate body 210 is hingedly connected with the rotating shaft boss 230 and the fixing strip 240.

[0072] In one embodiment of the present application, the liquid cooling joint anti-leakage liquid diversion mechanism 10 further includes a reset assembly 300 for restoring the shielding plate assembly 200 from the avoidance state to the shielding state. The reset assembly 300 mainly includes the reset power structure 310 and a limiter 320. The reset power structure 310 is fixedly mounted on the anti-leakage liquid box assembly 100, and its output end is connected to the shielding plate assembly 200.

[0073] The present application does not limit the specific structure of the reset power structure 310. For example, in one embodiment of the present application, Figure 4 As shown, the resetting power structure 310 is a torsion spring, one end of which is inserted into a groove (not shown) provided on the shielding plate body 210, and the other end is sealed against the inner wall of the box body 110. In this embodiment, the power for resetting the shielding plate body 210 is provided by the elastic deformation of the torsion spring.

[0074] In another embodiment of the present application, the reset power structure 310 is not a torsion spring, but Figure 7As shown, it includes a rack 312, a gear 313, a reset elastic member 314 and a reset pin 315. The reset pin 315 is fixedly mounted on the top of the liquid storage chamber 111, with the first end being arranged close to the first joint port 113, and the second end being arranged close to the second joint port 114. The first end of the reset pin 315 is sleeved with the reset elastic member 314 in a compressed state, and the second end of the reset pin 315 is sleeved with the rack 312. The gear 313 is fixedly mounted on the top of the rotating shaft 220, and is meshed and connected with the rack 312. In this embodiment, the power for resetting the shielding plate body 210 is provided through the elastic deformation of the reset elastic member 314, and the power is transmitted to the shielding plate body 210 through the rack 312 and the gear 313.

[0075] like Figure 6 As shown, the reset assembly 300 further includes a stopper 320 for maintaining the gap between the shielding plate body 210 and the first joint port 113. The stopper 320 is disposed between the first joint port 113 and the shielding plate body 210 to prevent the reset power structure 310 from pushing the shielding plate body 210 too much toward the first joint port 113, thereby closing the gap between the shielding plate body 210 and the first joint port 113. In the present application, the stopper 320 is not a necessary structure, for example, Figure 7 As shown, in another embodiment of the present application, the shielding plate body 210 is in an arc shape bent toward the liquid storage chamber 111. At this time, even if the limiting member 320 is not provided, the gap between the shielding plate body 210 and the first joint port 113 can be maintained.

[0076] In one embodiment of the present application, the liquid-cooling joint anti-leakage diversion mechanism 10 also includes a diversion component 400, which is used to divert the leaked liquid to a drain (not shown in the figure), and the input end of the diversion component 400 is connected to the liquid storage chamber 111, and the output end is connected to the drain.

[0077] In one embodiment of the present application, Figure 1 and Figure 2 As shown, the flow guide assembly 400 includes an "L"-shaped flow guide tube 410 and an "I"-shaped flow collector 430, wherein the input end of the flow guide tube 410 is connected to the liquid storage chamber 111, and the output end of the flow guide tube 410 is connected to the flow collector 430. Figure 1 and Figure 2 As shown, there are multiple flow guide pipes 410, which are arranged in a substantially horizontal direction. There is only one confluence pipe 430, which is connected to the output end of the flow guide pipe 410, collects the liquid in the multiple flow guide pipes 410 and guides it to the drainage.

[0078] In another embodiment of the present application, the diversion assembly 400 further includes a liquid collecting box 420. The liquid collecting box 420 is installed on the front side of the confluence pipe 430. Its input end is set to an open state, and its output end is communicated with the confluence pipe 430. The diversion pipe 410 is set such that when the baffle assembly 200 is in the blocking state, its output end is directly communicated with the input end of the liquid collecting box 420; when the baffle assembly 200 is in the避让 state, its output end is directly communicated with the input end of the confluence pipe 430.

[0079] Specifically, as Figure 1 and Figure 2 shown, the confluence pipe 430 is provided with a first confluence port 431 and a second confluence port 432. Each U position corresponds to a set of the first confluence port 431 and the second confluence port 432. The first confluence port 431 and the second confluence port 432 are arranged in the vertical direction. The first confluence port 431 is used to enable the output end of the diversion pipe 410 to be directly inserted into the confluence pipe 430; the second confluence port 432 is used to communicate with the liquid collecting box 420. When the baffle assembly 200 is in the blocking state, the output end of the diversion pipe 410 is arranged above the liquid collecting box 420, and the liquid falls into the liquid collecting box 420 under the action of gravity and is collected into the confluence pipe 430 through the second confluence port 432. When the baffle assembly 200 is in the避让 state, the output end of the diversion pipe 410 passes through the first confluence port 431 and is directly communicated with the input end of the liquid collecting box 420.

[0080] In an embodiment of the present application, as Figure 1 shown, the liquid collecting box 420 is generally in a "pin" shape as a whole. The second avoidance space 421 in the "pin" shape is used to avoid the following liquid receiving tank 500. When the baffle assembly 200 is in the避让 state, the following liquid receiving tank 500 is just arranged in the second avoidance space 421.

[0081] As Figure 2 shown, the second sub-liquid storage cavity 1112 is provided with a guiding and positioning assembly 600. The guiding and positioning assembly 600 is used to slidably install the anti-leakage liquid box assembly 100 on the first component 20. The guiding and positioning assembly 600 includes a positioning pin 610 and a guiding structure 620. The positioning pin 610 is fixedly installed on one of the first component 20 and the anti-leakage liquid box assembly 100, and the guiding structure 620 is fixedly installed on the other of the first component 20 and the anti-leakage liquid box assembly 100. As Figure 2As shown, in this embodiment, the positioning pin 610 is fixedly mounted on the first component 20, and the guide structure 620 is fixedly mounted on the box body 110. The free end of the positioning pin 610 is slidably arranged in the guide structure 620, so as to facilitate the liquid cooling joint anti-leakage liquid guiding mechanism 10 to move toward or away from the first component 20.

[0082] like Figure 2 As shown, the guide positioning assembly 600 further includes a positioning elastic member 630, which can prevent the positioning pin 610 from completely separating from the guide structure 620. One end of the positioning elastic member 630 is fixedly connected to the first component 20, and the other end is fixedly connected to the anti-leakage liquid box assembly 100. The anti-leakage liquid box assembly 100 is slidably connected to the first component 20 through the mutual cooperation of the positioning pin 610, the guide structure 620 and the positioning elastic member 630.

[0083] In one embodiment of the present application, Figure 8 As shown, the second component 30 includes a liquid leakage port 302. If there is a leak in the second joint 301 of the server, the liquid can be directed to the liquid leakage port 302. In order to collect the liquid from the liquid leakage port 302 and direct it to the drainage point, a liquid collecting groove 500 is further provided on the side wall of the box body 110. Figure 2 As shown, the liquid collecting tank 500 is arranged to be located below the liquid leakage port 302 when the shielding plate assembly 200 is in the shielding state, and is also connected to the guide assembly 400 .

[0084] like Figure 2 As shown, the bottom of the liquid collecting tank 500 is provided with an inclined guide surface 520, and the bottom of the liquid collecting tank 500 is provided with a second guide port 510, and the discharge end of the second guide port 510 is connected with the liquid storage chamber 111. When the shielding plate assembly 200 is in the shielding state, the second component 30 is connected with the first component 20, and if there is a leak in the second joint 301, the liquid will be discharged from the second component 30 through the leak port 302, and drip into the liquid collecting tank 500 under the action of gravity, and then discharged to the liquid storage chamber 111 through the guide surface 520 and the second guide port 510, and finally diverted to the discharge point.

[0085] like Figure 2As shown, when the liquid cooling joint anti-leakage liquid guiding mechanism 10 is in the first state, the positioning elastic member 630 is in a free state, and the liquid cooling joint anti-leakage liquid guiding mechanism 10 is at the farthest distance from the first component 20. The second component 30 is not connected to the first component 20, and the shielding plate assembly 200 is in a shielding state. At this time, the shielding plate body 210 of the shielding plate assembly 200 just blocks the front side of the first joint 201. If the first joint 201 fails, the sprayed liquid is blocked by the first joint 201, and flows into the liquid storage chamber 111 under the action of gravity, and then is introduced into the guiding pipe 410. The output end of the guiding pipe 410 is arranged above the liquid collecting box 420. The liquid falls into the liquid collecting box 420 under the action of gravity, and is collected into the confluence pipe 430 through the second confluence port 432, and is finally discharged to the drainage place.

[0086] like Figure 1 As shown, when the liquid-cooling joint anti-leakage liquid diversion mechanism 10 is in the second state, the second component 30 is close to the first component 20, and the second component 30 pushes the liquid-cooling joint anti-leakage liquid diversion mechanism 10 to move along the positioning pin 610 toward the direction close to the first component 20, and the positioning elastic member 630 is in a compressed state, and the liquid-cooling joint anti-leakage liquid diversion mechanism 10 is at the closest point to the first component 20. The second component 30 is connected to the first component 20, thereby realizing the conduction of the liquid. The baffle assembly 200 is pushed open by the first joint 201, and the baffle assembly 200 changes from the blocking state to the avoidance state. At this time, the liquid leakage port 302 is above the liquid receiving tank 500. If there is a leak in the second joint 301, the liquid drips into the liquid receiving tank 500 through the liquid leakage port 302 under the action of gravity, and then is guided to the liquid storage chamber 111 through the guide surface 520 and the second guide port 510, and finally is guided to the drainage. At the same time, the interface between the first connector 201 and the second connector 301 is in the liquid storage chamber 111, and the guide tube 410 moves with the box body 110. At this time, the output end is inserted into the manifold 430, and the liquid is discharged to the discharge point through the guide tube 410 and the manifold 430 in turn.

[0087] When the second component 30 is pulled out, the second joint 301 is withdrawn from the first joint 201 of the first component 2 along with the second component 30. At this time, the liquid-cooling joint anti-leakage liquid diversion mechanism 10 is restored to the first state by the elastic force of the positioning elastic member 630. At this time, the limitation of the positioning elastic member 630 can prevent the liquid-cooling joint anti-leakage liquid diversion mechanism 10 from being completely separated from the first component 20.

[0088] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present invention. As long as these changes do not deviate from the concept of the present invention, they all belong to the protection scope of the present invention.
