Technical Field

[0001] The invention belongs to the technical field of liquid cooling system sealing, and in particular relates to a transition self-sealing joint and a liquid cooling system. Background Art

[0002] As the integration of electronic systems becomes increasingly high, the heat density of the system increases, and the choice of heat dissipation method tends to be liquid cooling technology. Liquid cooling technology has the advantages of low noise, small size, and high heat dissipation efficiency.

[0009] As a preferred embodiment, the head end of the seal is provided with a liquid flow channel I, the first port of the liquid flow channel I is arranged on the head end face of the seal, and the second port of the liquid flow channel I is arranged on the outer cylindrical surface of the head end of the seal cooperating with the plug-in cavity.

[0010] As a preferred embodiment, the liquid flow channel I includes a flow channel I and a liquid flow groove I. The liquid flow groove I is located on the head end surface of the seal. The flow channel I is formed on the side wall of the liquid flow groove I and is radially penetrated by the seal.

[0013] As a preferred solution, the plug-in section is formed with a transfer cavity along the axial direction, one end of the transfer cavity is connected to the cavity III of the connecting section, and the other end is used to dock with the port of the liquid flow channel I, and the cavity III is used to install the sensor.

[0014] As a preferred embodiment, the seal includes a large diameter section located at the tail end and a small diameter section located at the head end, wherein the large diameter section and the small diameter section are axially connected, the large diameter section is located in cavity I and can move along the axial direction of cavity I, and the small diameter section can extend into the plug-in cavity to achieve flow channel closure.

[0015] As a preferred solution, a stop surface is formed at the head end of the large diameter section, and the stop surface cooperates with the head end surface of the cavity I to form a stop limit for the seal to move in the extension direction of the elastic member.

[0018] A second object of the present invention is to provide a liquid cooling system, comprising any one of the above-mentioned transition self-sealing joints.

[0019] Compared with the prior art, the present invention has at least the following beneficial effects: First, the present invention improves the convenience of the replacement process through structural optimization. The process of replacing the sensor is simple and reasonable, and there is no need to stop the machine for replacement.

The self-sealing joint of the present invention includes a fixed seat and an adapter seat. The sensor is fixed on the adapter seat, and the head end of the adapter seat cooperates with the plug-in cavity of the fixed seat. When the adapter seat is extended into the plug-in cavity of the fixed seat and is in place, the flow channel between the joint and the sensor is connected, and the sensor is used for normal monitoring, which can ensure that the sensor measures the system parameters in time. When the adapter seat is disassembled, the head end of the adapter seat withdraws from the plug-in cavity to the outside, and the flow channel between the joint and the sensor is cut off.

[0020] Secondly, this solution also takes into account that during the threaded connection between the adapter and the fixed seat, there will be a certain amount of friction during the relative rotation of the adapter and the moving end faces of the seal. This solution reduces the contact area between the end faces of the two heads by setting a liquid flow groove at the center of the seal to correspond to the adapter cavity at the head end of the adapter. Therefore, during operation, the relative screwing and separation torques of the two will also be smaller, which can facilitate operation for operators.

[0021] Third, in this solution, a seal is used to seal the plug-in cavity, thereby preventing liquid leakage during sensor replacement. At least two sealing rings are arranged in the plug-in cavity. The purpose of such design is to fully consider the combination with the sensor replacement process of this solution and the structure of the above-mentioned self-sealing joint. In order to ensure that during the sensor replacement process, the sealing ring can always achieve a sealed fit with the head end of at least one component of the seal or the adapter, so as to avoid leakage of internal pressure of the liquid cooling system.

[0025] The present invention is described in detail below by means of exemplary embodiments. However, it should be understood that, without further description, elements, structures and features in one embodiment may also be beneficially combined in other embodiments.

[0026] It should be noted that, unless otherwise defined, the technical terms or scientific terms used herein shall have the usual meanings understood by persons with ordinary skills in the field to which the invention belongs. The words "one", "an" or "the" and the like used in the patent application specification and claims of the present invention do not express quantitative limitations, but indicate the existence of at least one. Words such as "include" or "comprise" indicate that the elements or objects appearing before "include" or "comprises" include the elements or objects listed after "include" or "comprises" and their equivalents, but do not exclude other elements or objects with the same function.

[0027] As shown in the figure, this embodiment provides a transfer self-sealing joint, including a fixed seat 10 and a transfer seat 20, and the tail end of the transfer seat 20 is used to install a sensor 30. The tail end of the fixed seat 10 is connected to the interface of the liquid cooling module, and the head end transfer seat 20 of the fixed seat 10 is detachably connected (the fixed seat 10 and the transfer seat 20 are both plugged into one end as their respective head ends), the fixed seat 10 includes a shell 1 and a seal 2, the shell 1 is axially formed with a cavity I11 and a plug-in cavity 12, the cavity I11 and the plug-in cavity 12 are connected, the fixed seat 10 and the transfer seat 20 have two states, one is the connection state of the two, the head end of the transfer seat 20 can be extended into the plug-in cavity 11, and the seal 2 is moved forward along the axial direction of the shell 1 to realize the opening of the flow channel, and the other is the separation state of the two, after the head end of the transfer seat 20 is withdrawn from the plug-in cavity 11, the head end of the seal 2 can be extended into the plug-in cavity 11, thereby realizing the closing of the flow channel. In the process of replacing the sensor 30, as the adapter 20 is pulled out, the head end of the seal 2 can naturally reset into the plug cavity 11, thereby cutting off the flow channel, so that the liquid will not overflow. The self-sealing joint of this solution has the characteristics of fast replacement and no leakage.

[0028] In this solution, at least two axially arranged sealing rings are provided inside the plug-in cavity 11. This embodiment takes the case where two O-rings are provided in the plug-in cavity 11 as an example. The O-rings include sealing ring I4 and sealing ring II5, wherein sealing ring I4 and sealing ring II5 are provided along the axial direction of the plug-in cavity 11 and fixed in an annular groove inside the plug-in cavity 11. The purpose of providing at least two sealing rings in this solution is to ensure that during the sensor replacement process, there is always at least one sealing ring that can cooperate and seal with the head end cylinder of the seal 2 and / or the head end cylinder of the adapter 20.

[0029] like Figure 4As shown, when the adapter 20 is threadedly connected with the fixed base 10, the head end plug-in section 201 of the adapter 20 extends into the plug-in cavity 12, and the outer cylindrical surface of the plug-in section 201 can be sealed with the sealing ring II5 and the sealing ring I4 in turn, so that a double sealing effect is achieved through the double sealing rings. When the adapter 20 is separated from the fixed base 10, the adapter 20 is screwed, and the plug-in section 201 of the adapter 20 is withdrawn from the plug-in cavity 12 to the outside, and the small diameter section 21 of the sealing member 2 is then extended into the plug-in cavity 12 and is sealed with the sealing ring I4. At this time, the plug-in section 201 is first separated from the sealing ring I4, and then separated from the sealing ring II5, and finally achieves a double sealing effect with the fixed base 10. Completely detached, when the sensor 30 is replaced, the adapter seat 20 and the sensor 30 are formed into an integral part, and the integral part is screwed relative to the fixed seat 10, and the outer cylindrical surface of the plug-in section 201 first cooperates with the sealing ring Ⅱ5 to achieve a seal, and at this time, the small diameter section 21 of the sealing member 2 also cooperates with the sealing ring Ⅰ4 to achieve a seal, as the plug-in section 201 is further extended, the adapter seat 20 will further push the sealing member 2 back, and then, the head end of the sealing member 2 withdraws from the plug-in cavity 12, and the plug-in section 201 finally achieves a sealing cooperation with the sealing ring Ⅱ5 and the sealing ring Ⅰ4 at the same time. During the entire plug-in process, it is always ensured that the sealing ring can achieve a sealing cooperation with the moving parts in the plug-in cavity 12.

[0030] In this solution, the plug-in cavity 11 is a bell-mouth structure at the plug-in interface 121 at one end of the seal 2. The purpose of such design is to facilitate the seal 2 to automatically enter the plug-in cavity 12 more smoothly under the elastic force of the elastic member 3. In order to cooperate with the bell-mouth structure, a transition slope 211 is provided at the connection between the small diameter section 21 and the large diameter section 22. The transition slope 211 is located at the root circumference of the small diameter section 21 and is used to cooperate with the bell-mouth to better achieve the sealing effect of the seal 2.

[0031] In this solution, the flow channel can be implemented as follows: the head end of the seal 2 is provided with a liquid flow channel I, wherein one end of the liquid flow channel I is provided on the head end face of the seal 2, and the other end of the liquid flow channel I is provided on the head end outer cylindrical surface of the seal 2. Specifically, the liquid flow channel I includes a flow channel I23 and a liquid flow groove I24. The liquid flow groove I24 is located at the center of the head end face of the small diameter section 21. The side wall of the liquid flow groove I24 is formed with the flow channel I23 that is set through. According to design requirements, the flow channel I23 can be arranged along the radial direction of the small diameter section 21, and several flow grooves I24 are arranged circumferentially. Such a design ensures that the liquid flows through the flow channel I23, so that the liquid flow can be prevented from flowing into the sensor 30 side too quickly when the flow channel is turned on, and the liquid cooling system is kept stable. During the process of inserting the head end plug-in section 201 of the adapter 20 into the plug-in cavity 12, as the adapter 20 is continuously twisted, the push-in seal 2 retreats in the direction of the compression elastic member 3, and then when the flow channel Ⅰ23 is gradually exposed outward from the plug-in cavity 12 (specifically as shown in the figure, when the flow channel Ⅰ23 enters the plug-in interface 121 position), the flow channel can be slowly opened, and the above-mentioned two or more sealing rings can ensure that no leakage will occur during the operation.

[0032] In this solution, in order to ensure that the seal 2 can automatically reset to achieve the sealing of the plug-in cavity 11 when the adapter seat 20 moves outward from the fixed seat 10, thereby preventing the liquid from overflowing from the liquid cooling system, this solution also provides an elastic member 3 at the tail of the seal 2. Preferably, the elastic member 3 adopts a compression spring, one end of the elastic member 3 is fixed in the cavity Ⅰ11 of the fixed seat 10, and the other end abuts against the seal 2. More specifically, a stop ring 6 is provided near the tail position in the cavity Ⅰ11, and the stop ring 6 is installed at the installation step 14 of the cavity Ⅰ11. The installation step 14 is provided with a mounting groove 15 on one side of the axial direction near the tail. The mounting groove 15 is annular and is arranged circumferentially inside the tail end of the cavity Ⅰ11. A retaining spring 7 is provided in the mounting groove 15, and one side of the retaining spring 7 contacts with the stop ring 6, thereby forming an axial stop limit for the stop ring 6. A stop step Ⅰ27 is provided on the outer cylindrical surface of the sealing ring 2, and the stop step Ⅰ27 is annular and is arranged circumferentially along the sealing ring 2. The end of the elastic member 3 is sleeved by the tail end of the seal 2 and abuts against the stop step Ⅰ27. When the head end of the adapter seat 20 is inserted into the plug-in cavity 11, the end face Ⅱ206 of the adapter seat 20 contacts the head end face Ⅰ29 of the seal 2. As the adapter seat 20 is continuously screwed, the elastic member 3 gradually accumulates the reverse elastic force for restoring the seal 2. When the adapter seat 20 is pulled out, the seal 2 moves toward the head end and loses the obstruction of the adapter seat 20. Therefore, the restored elastic force accumulated by the elastic member 3 can automatically push the seal 2 outward, so that the head end of the seal 2 can smoothly enter the plug-in cavity 12, thereby achieving sealing cooperation with the sealing ring.

[0033] In this embodiment, the fixing seat 10 is further provided with a cavity II13 along the axial direction, and the cavity I11, the plug-in cavity 12, and the cavity II13 are connected in sequence and coaxially arranged. Preferably, the cross-sectional diameters of the cavities I11 and II13 are larger than the cross-sectional diameter of the plug-in cavity 11, thereby forming a through cavity that is thin in the middle and thick at both ends. An internal thread is provided inside the cavity II1313, and the function of the cavity II13 is to realize a threaded connection with the external thread of the adapter seat 20.

[0034] In this solution, since the integral part composed of the adapter seat 20 and the sensor 30 is threadedly connected to the fixed seat 10 when just screwed together, the head end of the plug-in section 201 of the adapter seat 20 is aligned with the plug-in cavity 12, and the threaded screwing structure also provides axial thrust for the plug-in process of the plug-in section 201. In the subsequent process of screwing the integral part, there will be no problems of inaccurate alignment and difficulty in installation. During the operation, the O-ring always performs a sealing function and there will be no leakage or other problems.

[0035] In a typical embodiment of the present invention, the seal 2 includes a large diameter section 22 at the tail end and a small diameter section 21 at the head end, the large diameter section 22 and the small diameter section 21 are axially connected and coaxially arranged, wherein the large diameter section 22 at the tail end is arranged in the cavity Ⅰ11, and preferably, a stop step Ⅰ27 is arranged on the outer cylindrical surface of the large diameter section 22, the head end of the elastic member 3 is sleeved on the outer cylindrical surface of the large diameter section 22, and the head end of the elastic member 3 abuts against the stop step Ⅰ27, and the outer rib of the stop step Ⅰ27 of the large diameter section 22 is matched with the inner wall of the cavity Ⅰ11 to ensure that the seal 2 moves axially along the cavity Ⅰ11 and avoids radial movement. The stop surface 28 at the connection between the large diameter section 22 and the small diameter section 21 cooperates with the head end face of the cavity Ⅰ11 to achieve the stop limit of the seal 2 moving axially toward the plug-in cavity 12.

[0036] In this solution, a liquid flow groove Ⅰ24 is provided on the end face of the head end of the small diameter section 21, and a flow channel Ⅰ23 is radially provided on the small diameter section 21. One end opening of the flow channel Ⅰ23 is located on the outer cylindrical surface of the small diameter section 21, and the other end is located on the inner wall of the liquid flow groove Ⅰ24. When the seal 2 is pushed by the head end of the adapter seat 20 and the elastic member 3 is compressed and retreated toward the tail end, the small diameter section 21 is gradually pulled outward from the inside of the plug-in cavity 12. When the port of the flow channel Ⅰ23 located on the small diameter section 21 is exposed outward from the plug-in cavity 12, the liquid can enter from the port of the flow channel Ⅰ23 and then enter the sensor 30 at the tail end of the adapter seat 20 through the liquid flow groove Ⅰ24. In addition, the liquid flow groove Ⅰ24 is located on the head end face Ⅰ29 of the small diameter section 21. Its function is to collect the liquid flow entering the liquid flow groove Ⅰ24. On the other hand, the liquid flow groove Ⅰ24 is connected with the port of the head end adapter cavity 203 of the adapter seat 20, which also reduces the contact area between the end face Ⅰ29 of the seal 2 and the head end face Ⅱ206 of the adapter seat 20. The relative screwing and separation torques of the two will also be smaller, which can make it easier for operators to operate.

[0037] The structure of the adapter 20 is introduced as follows: the adapter 20 includes an insertion section 201 and a connecting section 202, wherein the outer cylindrical surface of the insertion section 201 cooperates with the insertion cavity 11, and the insertion section 201 can be inserted from the head end of the insertion cavity 11 and press the seal 2 to move axially toward the tail end. After the insertion section 201 is plugged into place, the insertion section 201 and the sealing ring in the insertion cavity 12 achieve a cooperative seal. The outer cylindrical surface of the connecting section 202 is formed with an external thread that matches the internal thread of the cavity II 13. Preferably, the outer cylindrical surface of the connecting section 202 is also provided with a stop step II 205 that matches the end stop of the fixing seat 10, thereby limiting the length of the plug-in section 201 entering the plug-in cavity 12. In the process of screwing the adapter seat 20 and the fixing seat 10, the threaded screwing can achieve the labor-saving effect of the plug-in process of the plug-in section 201 entering the plug-in cavity 12 (a certain axial force is required when the plug-in section 201 passes through the sealing ring in the plug-in cavity 12). The plug-in section 201 is formed with an adapter cavity 203 along the axial direction, and the connecting section 202 is formed with a cavity III 204 along the axial direction. The adapter cavity 203 and the cavity III 204 are connected. The cavity III 204 is provided with an internal thread for cooperating with the external thread 301 of the connector of the sensor 30 to achieve the threaded connection between the sensor 30 and the tail end of the adapter seat 20.

[0038] In this solution, it should be pointed out that during installation, if Figure 2 , 3 As shown, the external thread head of the sensor 30 is first rotated and fixed in the cavity III 204, so that the sensor 30 is connected to the rear end of the adapter 20 to form an integral part. Through the threaded engagement of the connecting section 202 and the cavity III 204, the plug-in section 201 at the head end of the integral part automatically faces the plug-in cavity 12, and the plug-in section 201 is gradually pushed into the plug-in cavity 11, and first cooperates with the sealing ring II5 to achieve sealing (such as Figure 5 As shown), when the head end face II206 of the plug-in section 201 abuts against the head end face I29 of the small diameter section 21 of the seal 2 (refer to Figure 6 ), as the whole piece continues to be screwed, the plug section 201 will push the sealing member 2 back and compress the elastic member 3, and the elastic member 3 gradually accumulates the restoring elastic force. When the flow channel I23 of the small diameter section of the sealing member 2 is exposed from the plug cavity 12 to the outside, the adapter seat 20 is connected to the fixed seat 10 in place and the flow channel is opened (refer to Figure 7 As shown), the liquid will flow along Figure 8The flow passage shown in the figure passes through the liquid flow groove II 26, the flow passage II 25, and enters the head end side of the large diameter section 22, and then passes through the flow passage I 23, the liquid flow groove I 24, and the adapter cavity 203 to reach the sensor 30. At this time, the outer cylindrical surface of the plug-in section 201 and the sealing ring II 5 and the sealing ring I 4 achieve a double sealing effect, and then the system parameters can be measured normally through the sensor 30. When the sensor 30 needs to be replaced or maintained, the adapter seat 20 and the sensor 30 are regarded as an integral part, and the integral part is rotated and separated relative to the fixed seat 10. At this time, the plug-in section 201 is gradually pulled outward from the plug-in cavity 11. Under the action of the reset force of the elastic member 3, the seal 2 will push the head end of the seal 2 into the plug-in cavity 11. When the seal 2 and the sealing ring I 4 are sealed in cooperation, the plug-in section 201 and the sealing ring II 5 are sealed in cooperation. As the integral part continues to rotate and separate, the adapter seat 20 and the fixed seat 10 are separated (the plug-in section 201 and the sealing ring II 5 are separated). The sensor 30 can then be removed from the adapter 20 for replacement or maintenance. The process of reinstalling and replacing the sensor 30 can refer to the above operating steps.

[0039] The embodiment of the present invention also provides a liquid cooling system, including a liquid cooling module, wherein the above-mentioned adapter self-sealing joint is arranged at the interface of the liquid cooling module, the rear flange of the fixing seat 10 is connected to the interface of the liquid cooling module, and the end faces of the connection between the two are sealed by a sealing ring III8, and the sealing ring III8 can be fixed on the end face of the rear flange of the fixing seat 10, and the sensor 30 is installed on the fixing seat 10 through the adapter seat 20, and the sealing ring IV9 can be arranged at the end face of the rear end of the adapter seat 20, and the sensor 30 and the tail end of the adapter seat 20 are sealed by the sealing ring IV9. In this solution, the sealing ring III8 and the sealing ring IV9 are both O-rings. In this solution, the adapter self-sealing joint is always in a sealed state during the replacement, operation, and use of the sensor, and the internal pressure and liquid of the liquid cooling system will not leak out, so that the parameters of the liquid cooling system can be accurately measured.
