DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0037] With reference to Figure 1 and Figure 2 The connector 100 in the embodiments of the present application can be used to connect the server 10 and the cabinet 20. When the server 10 is immersed in the cooling liquid in the cabinet 20, the server 10 can establish a flow channel with the cabinet 20 through the connector 100, so that the circulation of the cooling liquid between the server 10 and the cabinet 20 can be realized.

[0038] The connector 100 can include a connector plug 110 and a connector socket 120. The connector socket 120 can be fixed in the cabinet 20, and the connector plug 110 is connected to the server 10. When the server 10 is fixed in the cabinet 20, the connector plug 110 is plugged into the connector socket 120. When the connector plug 110 and the connector socket 120 are plugged, the server 10 and the cabinet 20 are connected through the connector 100.

[0039] It is worth mentioning that the server 10 in the embodiment can be internally provided with a plurality of heat generating elements, which can be high-power chips for example, and each chip can be provided with a heat sink 11 for heat exchange with the chip, and the heat sink 11 can flow with cooling liquid to exchange heat with the chip and cool the chip. When the connector 100 connects the server 10 and the cabinet 20, the heat sink 11 can be connected to the connector 100 through the pipeline 12, and the cooling liquid in the heat sink 11 that is heated after heat exchange with the chip flows into the connector 100 through the pipeline 12, and then flows into the cabinet 20 through the connector 100. Therefore, when the connector 100 establishes a flow channel between the server 10 and the cabinet 20, the flow path of the cooling liquid in the flow channel is from the heat sink 11 inside the server 10 to the cabinet 20.

[0040] Of course, the server 10 is additionally provided with a joint device (not shown in the figure) to communicate with the cabinet 20 through the joint device, so that the low-temperature cooling liquid in the cabinet 20 can flow into the heat sink 11 in the server 10 through the joint device, and the low-temperature cooling liquid exchanges heat with the chip to reduce the temperature of the chip. In this way, the joint device cooperates with the connector 100 to enable the cooling liquid to circulate between the heat sink 11 inside the server 10 and the cabinet 20, thereby achieving efficient heat dissipation of the chips inside the server 10.

[0041] As shown in Figure 1 The cabinet 20 is provided with a partition 21 connected to the side wall of the cabinet 20, so that the space inside the cabinet 20 can be divided into two independent spaces, the space between the partition 21 and the bottom of the cabinet 20 can be regarded as a liquid outlet space 23, and the space between the partition 21 and the top of the cabinet 20 can be regarded as a liquid inlet space 22. The side wall of the cabinet 20 is provided with a liquid inlet 24 and a liquid outlet 25 corresponding to the liquid inlet space 22 and the liquid outlet space 23, so that the low-temperature cooling liquid can flow into the cabinet 20 through the liquid inlet 24, and the cooling liquid that is heated after heat exchange with the chip in the server 10 can flow out through the liquid outlet 25.

[0042] On this basis, the connector socket 120 can be fixed to one side of the partition 21 facing the liquid inlet space 22, and when the server 10 is placed in the cabinet 20, the server 10 is located in the liquid inlet space 22. The connector socket 120 can also communicate with the liquid outlet space 23, and when the cooling liquid in the liquid inlet space 22 enters the server 10 to dissipate heat from the chip, the heated cooling liquid can flow to the liquid outlet space 23 through the connector 100. In this way, by providing the partition 21 to separate the liquid inlet space 22 and the liquid outlet space 23, the cooling liquids of different temperatures can be prevented from mixing together to affect the temperature of the cooling liquid entering the server 10, thereby facilitating the improvement of the heat dissipation effect.

[0043] In some embodiments, with reference to Figure 1 , Figure 3 and Figure 4 together, the connector plug 110 is internally provided with a first flow channel 111 which penetrates the connector plug 110 in an axial direction so that both ends of the first flow channel 111 are in communication with the outside of the connector plug 110. Here, the axial direction of the connector plug 110 can also be understood as the plugging direction of the connector plug 110 and the connector socket 120. When the connector plug 110 is connected to the server 10, one end of the first flow channel 111 is in communication with the inside of the server 10 so that the cooling liquid inside the server 10 flows out through the first flow channel 111.

[0044] The connector plug 110 can include a connecting seat 112 which is provided with a plugging structure 113 and a connecting structure 114 on both sides, respectively, wherein the connecting structure 114 is used for connecting with the server 10, and the plugging structure 113 is used for plugging with the connector socket 120.

[0045] The inside of the connector socket 120 is provided with a second flow channel 121 which penetrates the connector socket 120 in an axial direction so that both ends of the second flow channel 121 are in communication with the outside of the connector socket 120. The plugging structure 113 can be inserted into the second flow channel 121 from one end of the second flow channel 121, at this time, the first flow channel 111 and the second flow channel 121 are in communication, and the cooling liquid in the first flow channel 111 flows into the second flow channel 121. While the second flow channel 121 can be in communication with the liquid outlet space 23, the cooling liquid flowing into the second flow channel 121 flows into the liquid outlet space 23.

[0046] As shown in Figure 3 , the second flow channel 121 is further provided with a sealing assembly 122 which is connected to the inner wall of the second flow channel 121 in the circumferential direction of the second flow channel 121. When the sealing assembly 122 is in an initial state (i.e. the connector plug 110 is not plugged into the connector socket 120), the sealing assembly 122 can be used to isolate the spaces on both sides of the sealing assembly 122 of the second flow channel 121 from each other, and the liquid on one side of the sealing assembly 122 cannot flow to the other side of the sealing assembly 122 through the sealing assembly 122. When the plugging structure 113 is plugged into the second flow channel 121, the plugging structure 113 can be arranged through the sealing assembly 122, so that the first flow channel 111 and the second flow channel 121 are in communication. Moreover, when the plugging structure 113 is arranged through the sealing assembly 122, the sealing assembly 122 can also be wrapped around the surface of the plugging structure 113 in the circumferential direction of the plugging structure 113.

[0047] It can be understood that the connector 100 in the embodiment can play a sealing role on the second flow passage 121 when not in use, preventing the cooling liquid in the liquid inlet space 22 from flowing out through the second flow passage 121. When the connector 100 is in use, the plug structure 113 is located in the second flow passage 121, and the sealing assembly 122 can also be in contact with the outer wall of the plug structure 113, so that the passage between the first flow passage 111 and the second flow passage 121 is blocked by the sealing assembly 122, thereby further preventing the cooling liquid in the liquid inlet space 22 from flowing out through the second flow passage 121, and ensuring that only the cooling liquid in the server 10 can flow out through the second flow passage 121.

[0048] In some embodiments, with continued reference to Figure 3 , the sealing assembly 122 can include at least one sealing rubber block 1221, which is fixed to the inner wall of the second flow passage 121 along the circumference of the second flow passage 121. Exemplarily, the inner wall of the second flow passage 121 is provided with a concave groove along the circumference, and the sealing rubber block 1221 can be clamped in the groove, so as to not only facilitate the fixation of the sealing rubber block 1221, but also avoid leaving a gap between the sealing rubber block 1221 and the inner wall of the second flow passage 121, so as to achieve a better sealing effect.

[0049] Specifically, the center of the sealing rubber block 1221 has a through hole, and when the sealing rubber block 1221 is in an initial state, the parts around the through hole of the sealing rubber block 1221 can be pressed against each other, thereby blocking the through hole. When the plug structure 113 is inserted into the second flow passage 121, the plug structure 113 can press the rubber around the through hole, so that the plug structure 113 can pass through the through hole. At this time, the rubber around the through hole will rebound under the elastic force, thereby tightly wrapping the surface of the plug structure 113. In this way, when the plug structure 113 is arranged in the sealing rubber block 1221, there is almost no gap between the sealing rubber block 1221 and the plug structure 113, thereby achieving a good sealing effect.

[0050] Further, as shown in Figure 3 , when the sealing rubber block 1221 is one, the sealing rubber block 1221 can be arranged at a position close to the end of the second flow passage 121. In this way, when servers 10 of different sizes are connected through the connector plug 110 and the connector socket 120, the plug structure 113 can pass through the sealing rubber block 1221, thereby avoiding the situation that the length of the plug structure 113 is not enough to pass through the sealing rubber block 1221. That is, arranging the sealing rubber block 1221 at a position close to the end of the second flow passage 121 can adapt to servers 10 of different sizes, and has higher applicability.

[0051] In addition, when the server 10 is taken out of the cabinet 20, the plug structure 113 is pulled out of the second flow passage 121, at this time, the sealing rubber block 1221 can also be restored to the state of blocking the through hole under the elastic action, and further can continue to play the sealing role.

[0052] When the sealing rubber block 1221 is two or more, each sealing rubber block 1221 can be arranged at intervals along the extension direction of the second flow passage 121. Referring again to Figure 3 For example, when two sealing rubber blocks 1221 are arranged, one of the sealing rubber blocks 1221 is arranged at a position close to the end of the second flow passage 121, and the other sealing rubber block 1221 can be arranged at the middle of the second flow passage 121, and both of the sealing rubber blocks 1221 can be fixed by the groove arranged on the inner wall of the second flow passage 121.

[0053] It can be understood that when the number of sealing rubber blocks 1221 is two or more, the sealing effect of the sealing assembly 122 on the second flow passage 121 can be improved, thereby further preventing the cooling liquid in the cabinet 20 from leaking from the second flow passage 121.

[0054] In addition, the thickness of the sealing rubber block 1221 arranged close to the end of the second flow passage 121 can also be greater than the thickness of the other sealing rubber blocks 1221, since the sealing rubber block 1221 arranged close to the end of the second flow passage 121 directly contacts the cooling liquid in the cabinet 20, when the sealing effect of the sealing rubber block 1221 is improved by increasing the thickness, the cooling liquid in the cabinet 20 can be better blocked.

[0055] In some embodiments, referring to Figure 3 and Figure 4 , the plug structure 113 can include a first plug portion 1131 and a second plug portion 1132, the first plug portion 1131 and the second plug portion 1132 are arranged in the direction in which the connector plug 110 points to the connector socket 120, and the radial dimension of the second plug portion 1132 is smaller than the radial dimension of the first plug portion 1131. When the plug structure 113 is inserted into the second flow passage 121, the second plug portion 1132 enters the second flow passage 121 and passes through the sealing rubber block 1221, on the one hand, the size of the second plug portion 1132 is small, and it is more convenient for the second plug portion 1132 to be blindly inserted into the second flow passage 121, on the other hand, the second plug portion 1132 with smaller size is easier to pass through the sealing rubber block 1221, thereby completing the plug between the connector plug 110 and the connector socket 120.

[0056] In the embodiment, when the plug structure 113 is inserted into the second flow passage 121, the first plug portion 1131 abuts against the sealing rubber block 1221 close to the end of the second flow passage 121. Since the radial dimension of the first plug portion 1131 is larger than that of the second plug portion 1132, the extrusion effect between the first plug portion 1131 and the sealing rubber block 1221 is enhanced, so that the sealing effect between the first plug portion 1131 and the sealing rubber block 1221 is better.

[0057] Further, referring to Figure 4 and Figure 6 , the surface of the plug structure 113 can also be provided with a sealing rubber ring 115, which is arranged around the circumference of the plug structure 113. When the plug structure 113 is inserted into the second flow passage 121, the sealing rubber ring 115 can abut against at least one sealing rubber block 1221. Since the surface of the plug structure 113 is smooth, when the sealing rubber ring 115 is provided, the extrusion effect between the sealing rubber ring 115 and the sealing rubber block 1221 is enhanced, so that the abutment between the sealing rubber ring 115 and the sealing rubber block 1221 is more compact, thereby improving the sealing effect.

[0058] In particular implementation, the sealing rubber ring 115 can be arranged on the first plug portion 1131, and the surface of the second plug portion 1132 is not provided with the sealing rubber ring 115. In this way, the resistance of the second plug portion 1132 passing through the sealing rubber block 1221 is reduced, and the contact area between the sealing rubber ring 115 and the sealing rubber block 1221 is increased, so as to further improve the sealing effect.

[0059] For example, the sealing rubber ring 115 on the first plug portion 1131 can abut against the sealing rubber block 1221 close to the end of the second flow passage 121, so that the cooling liquid directly entering the second flow passage 121 from the end of the second flow passage 121 can be better prevented.

[0060] In some embodiments, referring to Figure 6 , the second flow passage 121 can also be provided with a sealing rubber layer 123 and a spring 124. The sealing rubber layer 123 is located on the side of the sealing rubber block 1221 away from the connector plug 110, and the spring 124 is arranged on the side of the sealing rubber layer 123 away from the sealing rubber block 1221. The two ends of the spring 124 are connected to the sealing rubber layer 123 and the inner wall of the second flow passage 121 respectively, so that the spring 124 can stretch and contract along the plug direction of the connector plug 110 and the connector socket 120. When the spring 124 is in the initial state (i.e., the connector plug 110 is not plugged into the connector socket 120), the spring 124 is in the compressed state, and the sealing rubber layer 123 abuts against the sealing rubber block 1221.

[0061] In detail, referring to the drawings together Figure 6 and Figure 7 The sealing rubber layer 123 can include a fixed ring 1231 and a plurality of sealing flaps 1232 connected to the fixed ring 1231, the plurality of sealing flaps 1232 being connected to the inner ring wall of the fixed ring 1231 in the circumferential direction of the fixed ring 1231. Each of the sealing flaps 1232 has a free end away from the fixed ring 1231 and respectively extends towards the center of the fixed ring 1231, and when the sealing rubber layer 123 is in the initial state, each of the sealing flaps 1232 is perpendicular to the axis of the fixed ring 1231, at this time, each of the sealing flaps 1232 can cooperate to form a large circular baffle, which fills the space surrounded by the fixed ring 1231. When the sealing rubber layer 123 abuts against the sealing rubber block 1221, the sealing rubber layer 123 can be opposite and cover the part of the sealing rubber block 1221 penetrated by the second insertion part 1132.

[0062] It can be understood that after the sealing rubber block 1221 is used for many times, the elasticity of the sealing rubber block 1221 is affected, and the sealing performance of the sealing rubber block 1221 is deteriorated. When the connector socket 120 is not used, the sealing rubber layer 123 can block the perforation of the sealing rubber block 1221, so as to ensure that the sealing effect of the second flow passage 121 is good, and the leakage of the cooling liquid is avoided.

[0063] When the connector plug 110 is inserted into the connector socket 120, after the second insertion part 1132 penetrates the sealing rubber block 1221 closest to the sealing rubber layer 123, the end of the second insertion part 1132 can press each of the sealing flaps 1232. Since the end of the sealing flap 1232 at the center of the fixed ring 1231 is a free end, in the process of moving downward, the second insertion part 1132 can press each of the sealing flaps 1232 along the radial direction of the fixed ring 1231, so that the sealing flaps 1232 are bent relative to the fixed ring 1231 to be parallel or nearly parallel to the axis of the fixed ring 1231, so that the second insertion part 1132 can penetrate the fixed ring 1231.

[0064] The spring 124 can be connected to the fixed ring 1231, and the radial dimension of the second insertion part 1132 can be substantially the same as the inner ring dimension of the fixed ring 1231. In this way, the second insertion part 1132 can contact and press the sealing flaps 1232, and in the process of continuing to move downward, the second insertion part 1132 can also act on the spring 124 so that the spring 124 is compressed. Since the inside of the spring 124 is a hollow structure, the cooling liquid in the first flow passage 111 can flow through the inside of the spring 124 and then flow out through the second flow passage 121.

[0065] It is worth mentioning that although the second plug-in part 1132 extrudes the sealing baffle 1232, the sealing baffle 1232 is not caused to pass through the second plug-in part 1132 due to elastic deformation, but is bent relative to the fixed ring 1231. That is, the sealing baffle 1232 has a small deformation amount during extrusion, and its elasticity is not greatly affected during repeated penetration by the second plug-in part 1132. When the second plug-in part 1132 leaves, the sealing baffle 1232 can rebound to a state perpendicular to the axis of the fixed ring 1231, so that the sealing rubber layer 123 can still have a good sealing effect when the connector socket 120 is not in use even after frequent use for multiple times.

[0066] In addition, the number of sealing baffles 1232 in the present embodiment can be designed according to actual use requirements. For example, the number of sealing baffles 1232 can be 4, and the sealing rubber layer 123 as a whole can have a cross tray structure. Alternatively, the number of sealing baffles 1232 can also be 3, 5, 6, etc.

[0067] In the present embodiment, considering that servers 10 of different sizes are connected to the cabinet 20 through the connector 100, the depth of the plug-in structure 113 inserted into the second flow passage 121 is different. When the length of the plug-in structure 113 inserted into the second flow passage 121 is relatively long, the second plug-in part 1132 extrudes the sealing baffle 1232 after passing through the sealing rubber block 1221, and the second plug-in part 1132 can fully extrude the sealing baffle 1232 to make the bending angle of the sealing baffle 1232 relative to the fixed ring 1231 large enough, and the port at the end of the second plug-in part 1132 can be completely exposed in the second flow passage 121. That is, at this time, more cooling liquid flows from the first flow passage 111 to the second flow passage 121 per unit time. When the length of the plug-in structure 113 inserted into the second flow passage 121 is relatively short, the second plug-in part 1132 can only slightly extrude the sealing baffle 1232 after passing through the sealing rubber block 1221, the bending angle of the sealing baffle 1232 relative to the fixed ring 1231 is small, and the free end of the sealing baffle 1232 will block part of the port of the first flow passage 111 at the end of the first plug-in part 1131, resulting in a small port area exposed in the second flow passage 121, and less cooling liquid flows from the first flow passage 111 to the second flow passage 121 per unit time.

[0068] Based on this, Figure 6To improve the speed of the cooling liquid flowing from the first flow passage 111 to the second flow passage 121, the side wall of the second plug-in part 1132 is further provided with an opening 1133 which is in communication with the first flow passage 111. That is, the cooling liquid in the first flow passage 111 can not only flow into the second flow passage 121 from the port of the first flow passage 111, but also flow into the second flow passage 121 through the opening 1133. In this way, when servers 10 of different sizes are immersed in the cabinet 20, the circulation speed of the cooling liquid between the servers 10 and the cabinet 20 can be ensured, thereby ensuring the heat dissipation effect.

[0069] In some embodiments, referring again to Figure 3 and Figure 4 , the connecting structure 114 of the connector plug 110 can include a first nut fixing part 1141 for fixing with the shell of the server 10 and a connecting joint 1142 for connecting with the internal pipeline 12 of the server 10. The first nut fixing part 1141 can include a first threaded rod 11411 connected to the connecting seat 112, a first nut 11412 threadedly matched with the first threaded rod 11411, and a gasket 11413 located on the side of the first nut 11412 facing the connecting seat 112. There is a certain gap between the connecting seat 112 and the first nut 11412. When the connector plug 110 is fixed with the shell of the server 10 through the first nut fixing part 1141, the connecting seat 112 is located outside the server 10, the first threaded rod 11411 penetrates the shell of the server 10, and the first nut 11412 and the gasket 11413 are located inside the server 10. At this time, the gasket 11413 and the connecting seat 112 are tightly attached to the inner and outer walls of the shell of the server 10, respectively, and the other side of the gasket 11413 is also tightly attached to the first nut 11412, so that the connector plug 110 can be stably connected with the server 10.

[0070] The connecting joint 1142 is connected to the side of the first threaded rod 11411 away from the connecting seat 112, which can be used to connect the pipeline 12 connected with the heat sink 11 inside the server 10, so that the cooling liquid can flow into the first flow passage 111 according to the preset route. In specific implementation, the connecting joint 1142 can be a tower joint or a quick twist joint.

[0071] Further, referring to Figure 3 and Figure 5The side of the connector socket 120 away from the connector plug 110 can also be provided with a second nut fixing part 127 for fixed connection with the partition plate 21. The second nut fixing part 127 can include a second threaded rod 1271 and a second nut 1272. When the connector socket 120 is fixedly connected with the partition plate 21, the end of the second threaded rod 1271 can pass through the partition plate 21 from the liquid inlet space 22 to the liquid outlet space 23, and the second nut 1272 is located in the liquid inlet space 22 and threadedly cooperates with the second threaded rod 1271.

[0072] On this basis, a sealing part 128 is further arranged between the second nut 1272 and the partition plate 21. The sealing part 128 can be made of rubber elastomer, for example. The sealing part 128 can be used to seal the gap between the second nut 1272 and the partition plate 21, so as to prevent the cooling liquid in the liquid inlet space 22 from directly flowing into the liquid outlet space 23.

[0073] It should be noted that the first nut fixing part 1141 and the second nut fixing part 127 are arranged in the embodiment, so that the connector plug 110 can be mounted or dismounted with the server 10, and the connector socket 120 can be mounted or dismounted with the partition plate 21, thereby facilitating individual maintenance.

[0074] In some embodiments, reference is made to Figure 6 and Figure 8 To facilitate fixed connection of the end of the spring 124 with the inner wall of the second flow passage 121, a fixing block 125 is further arranged in the second flow passage 121. The fixing block 125 is fixedly connected to the second flow passage 121 along the circumference of the second flow passage 121. The side of the fixing block 125 away from the inner wall of the second flow passage 121 is provided with a mounting groove 1251, so that the end of the spring 124 can be clamped into the mounting groove 1251 and fixed with the mounting groove 1251, thereby ensuring the connection stability of the spring 124 in the second flow passage 121.

[0075] The side of the fixing block 125 away from the spring 124 can also be provided with a check ring 126 fixed to the inner wall of the second flow passage 121 along the circumference of the second flow passage 121. The fixing block 125 can abut against the check ring 126, so that the check ring 126 can further improve the sealing effect in the second flow passage 121 while supporting the fixing block 125.

[0076] Based on the same design concept, reference is made to Figure 1 and Figure 3 The utility model embodiment can also provide an immersion liquid cooling system. The immersion liquid cooling system can include a cabinet 20, a server 10, and a connector 100 as described in the above embodiments.

[0077] Specifically, the inside of the cabinet 20 is provided with a partition plate 21, which can be used to separate the cabinet 20 into an independent liquid inlet space 22 and a liquid outlet space 23. The liquid inlet space 22 is filled with cooling liquid, the server 10 is immersed in the cooling liquid in the liquid inlet space 22, and the inside of the server 10 is in communication with the liquid inlet space 22. A plurality of high-power chips are arranged in the server 10, and the chips are provided with heat sinks 11 which can be used for heat exchange with the chips to cool the chips. When the cooling liquid in the cabinet 20 enters the inside of the server 10, it can flow into the heat sinks 11 arranged in each chip to precisely cool each chip.

[0078] The connector plug 110 of the connector 100 is connected to the server 10, and the first flow channel 111 of the connector plug 110 is in communication with the pipe 12 connected to the heat sink 11. The connector socket 120 is connected to the partition plate 21, and the second flow channel 121 of the connector socket 120 is in communication with the liquid outlet space 23. When the server 10 is immersed in the cooling liquid, the connector plug 110 is plugged into the connector socket 120, and the cooling liquid in the heat sink 11 which has completed heat exchange with the chip can flow into the liquid outlet space 23 through the pipe 12, the first flow channel 111 and the second flow channel 121 in turn.

[0079] In summary, the connector and the immersed liquid cooling system in the embodiment of the utility model can complete the connection of the server and the cabinet by plugging the connector plug into the connector socket when the server is immersed in the cabinet, which is convenient and fast. In addition, when the connector socket is not used, the sealing assembly can also seal the connector socket to prevent the cooling liquid in the cabinet from flowing out through the connector socket, thereby avoiding the leakage and waste of the cooling liquid.

[0080] Obviously, those skilled in the art can make various modifications and variations to the embodiments of the utility model without departing from the spirit and scope of the utility model. Therefore, if these modifications and variations of the utility model fall within the scope of the claims of the utility model and their equivalent technologies, the utility model also intends to include these modifications and variations.
