[0002] The liquid cooling radiator is installed on the cabinet wall. When the liquid cooling radiator is cooling, it needs to exchange the cooling liquid with the outside world through the cooling liquid pipeline. Therefore, the cooling liquid pipeline will be connected to the outside pipeline after passing through the cabinet wall. The inlet and outlet of the cooling liquid pipeline are located on the cabinet wall. When in use, part of the cooling liquid will overflow from the pipe mouth surface, and part of the cooling liquid will overflow into the cabinet wall, affecting the safety inside the cabinet.

[0003] There are two main existing solutions: 1. Fill expansion agent at the pipe mouth surface. When the coolant overflows into the cabinet wall, the expansion agent blocks the leakage route. However, the water absorption of the expansion agent at different positions is inconsistent, which leads to different expansion effects and easily causes coolant overflow. 2. Set sealing grooves and sealing protrusions to cooperate with each other to seal, but it has high requirements on processing accuracy and is easily damaged during disassembly and assembly.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of this application / this application to clearly and completely describe the technical solutions in the embodiments of this application / this application. Obviously, the described embodiments are only part of the embodiments of this application / this application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the application / this application and its application or use. Embodiment 1

[0020] This embodiment provides a pipeline wall-penetrating sealing structure to solve the problem that the pipeline wall-penetrating sealing structure in the prior art has poor sealing performance and requires high processing accuracy of each component.

[0021] refer to Figure 1 The liquid cooling radiator 2 is installed inside the cabinet wall 1 of the cabinet, and is connected to the external pipeline through multiple cooling liquid pipelines 3 through the preset perforations of the cabinet wall 1 to exchange cooling liquid, so its pipe opening surface 4 is outside the cabinet wall 1. The pipeline wall sealing structure provided in this embodiment includes a transition joint 5 for connecting the transition cooling liquid pipeline 3 with the external pipeline and preventing leakage; Fig.15 The outer wall of the coolant pipe 3 is provided with a first mounting groove 11 and a flange surface 10, referring to Figure 4 , Figure 5 and Figure 3 The first mounting groove 11 is sleeved with a replaceable second sealing ring 7, and the flange surface 10 is farther away from the pipe opening surface 4 of the coolant pipeline 3 than the first mounting groove 11. In the following text, most structures will have a perforation located on the outside of the cabinet wall 1, and the flange surface 10 is on the inside as one of the supports of the structure; refer to Fig. 9 The adapter 5 is provided with a first step 5.1 for limiting the insertion depth of the nozzle surface 4 of the coolant pipeline 3. It is worth noting that after the coolant pipeline 3 is inserted into the adapter 5, the first step 5.1 only limits the further penetration of the nozzle surface 4, but does not limit the exchange of coolant.

[0022] refer to Figure 1 , Figure 2 and Figure 3 When the coolant pipeline 3 passes through the cabinet wall 1, the coolant pipeline 3 is inserted into the adapter 5 and has a clearance fit with the inner wall (or inner cavity) of the adapter 5. The clearance can reduce the effect of the mismatch between the inner cavity of the adapter 5 and the coolant pipeline 3 due to low processing accuracy (such as concentricity tolerance). The remaining clearance ensures that the coolant pipeline 3 can be inserted into the adapter 5; the flange surface 10 and one side of the cabinet wall 1 are mutually abutted with each other by a replaceable first sealing gasket 6 as a gap, and the adapter 5 is connected to the other side of the cabinet wall 1. By replacing the first sealing gasket 6 with a suitable thickness, the connection tightness between the cabinet wall 1 and the flange surface 10 is adjusted, and then the sealing performance is improved by selecting the first sealing gasket 6 with the most suitable thickness. Since the coolant pipeline 3 and the adapter 5 are clearance fit, the second sealing ring 7 is required to seal the gap between the coolant pipeline 3 and the adapter 5. At the same time, the pipe mouth surface 4 is mutually abutted with the first step 5.1 by a replaceable third sealing gasket 8 as a gap to prevent the coolant from leaking from the pipe mouth surface 4. Similar to the first sealing gasket 6, the second sealing ring 7 of the most suitable size can be selected by replacement to adapt to the manufacturing tolerance between the adapter 5 and the coolant pipeline 3, so that the gap between the outer wall of the coolant pipeline 3 and the inner wall of the adapter 5 is elastically sealed by the second sealing ring 7, and the tightness between the pipe mouth surface 4 and the first step 5.1 can be adjusted by replacing the third sealing gasket 8 of the most suitable thickness.

[0023] When in use, first put the first sealing gasket 6 on the coolant pipeline 3, and push the first sealing gasket 6 to a position close to the flange surface 10. Then the coolant pipeline 3 passes through the preset perforation of the pipe wall 1, the first installation groove 11 is located on the outside of the pipe wall 1, and the flange surface 10 is blocked by the perforation on the inside of the pipe wall 1. The second sealing ring 7 is put on the first installation groove 11, and the second sealing ring 7 can make up for the concentricity tolerance between the outer diameter of the coolant pipeline 3 and the size of the inner surface 5.2. The third sealing gasket 8 is placed at the first step 5.1 of the inner cavity of the adapter 5. After ensuring that the two sides of the first sealing gasket 6 are respectively close to the flange surface 10 and the pipe wall 1, the adapter 5 is inserted into the coolant pipeline 3 from the pipe mouth surface 4 until the pipe mouth surface 4 is tightly against the third sealing gasket 8. The thickness of the first sealing gasket 6 can be changed to find a size that can effectively seal the perforation of the pipe wall 1, or the thickness of the third sealing gasket 8 can be changed at the same time to find a size that can effectively seal the pipe mouth surface 4. After finding the appropriate size, the pipe wall 1 and the adapter 5 are connected to fix the pipe wall sealing structure on the pipe wall 1 .

[0024] Connect the external pipeline to the adapter 5, and input and output the coolant to the liquid cooling radiator 2 to test the sealing degree.

[0025] The third sealing gasket 8 can be removed and the second sealing ring 7 can be retained. The sealing adapter 5 is used to connect one end of the external pipeline. The sealing ability of the second sealing ring 7 is tested by ventilation of the coolant pipeline 3, and the size that best suits the current manufacturing tolerance and clearance is found through continuous replacement.

[0026] refer to Figure 3 , taking the output of coolant as an example, when in use, the coolant is input from the pipe mouth of the coolant pipeline 3 through the adapter 5 to the external pipeline, and the third sealing gasket 8 seals the gap between the first step 5.1 and the pipe mouth surface 4 to prevent the coolant from leaking. If the third sealing gasket 8 fails to seal, the second sealing ring 7 seals the gap between the inner surface 5.2 of the adapter 5 and the outer wall of the coolant pipeline 3 to prevent the coolant from leaking. If the second sealing ring 7 also fails, the coolant spreads further along the outer wall of the coolant pipeline 3 toward the cabinet wall 1. Since the first sealing gasket 6 seals the gap between the flange surface 10 and the cabinet wall 1, the coolant can be prevented from spreading along the outer wall of the coolant pipeline 3 and leaking into the cabinet wall 1. In this case, the coolant may stop spreading and leaking due to the sealing effect between the adapter 5 and the cabinet wall 1, or leak out from the outside of the cabinet wall 1 from the gap between the adapter 5 and the cabinet wall 1. In either case, the coolant is effectively prevented from flowing into the cabinet wall 1.

[0027] At the same time, the sealing effect of the second sealing ring 7 and the third sealing gasket 8 will not be affected by uneven leakage and has a strong sealing effect.

[0028] The through-wall sealing structure of the pipeline provided in this embodiment relaxes the precision requirements for component manufacturing and reduces the manufacturing cost. By replacing the second sealing ring 7 and the third sealing gasket 8 of different sizes or thicknesses, the gap between the adapter 5 and the coolant pipeline 3 and the gap between the pipe mouth surface 4 and the first step 5.1 are sealed to meet the leakage-proof sealing requirements; even if the sealing of the second sealing ring 7 and the third sealing gasket 8 fails, the first sealing gasket 6 supported by the flange surface 10 can prevent the coolant from seeping into the cabinet wall 1; the adapter 5 is connected to the cabinet wall 1, with the flange surface 10 as a support, and the coolant pipeline 3 is indirectly fixed to the cabinet wall 1 through the flexible extrusion effect of the first sealing gasket 6, the second sealing ring 7 and the third sealing gasket 8, so as to prevent the occurrence of stress deformation gaps and ensure the sealing effect; therefore, it has considerable sealing ability and allows a gap between the adapter 5 and the coolant pipeline 3, which is suitable for lower manufacturing precision. Embodiment 2

[0029] This embodiment provides a wall-penetrating sealing structure for a pipeline. This embodiment is optimized on the basis of the first embodiment to improve the technical effect and refine the technical solution. For the contents not fully described in this embodiment, please refer to the first embodiment.

[0030] As one example, refer to Figure 3 , Fig.11 , and also includes a fourth sealing gasket 9. The adapter 5 is connected to the cabinet wall 1 with the fourth sealing gasket 9 as a gap. The fourth sealing gasket 9 is used to seal the side of the adapter 5 close to the cabinet wall 1. Three sealing lines are formed from the third sealing gasket 8 to the second sealing ring 7 and then to the fourth sealing gasket 9.

[0031] In addition, the addition of the fourth sealing gasket 9 forms a new enclosed space between the fourth sealing gasket 9 and the second sealing ring 7. According to the working principle of the second sealing ring 7, if the third sealing gasket 8 fails under the action of high-pressure coolant, the coolant leaks to the second sealing ring 7, the pressure difference on both sides of the second sealing ring 7 exceeds its sealing threshold, the second sealing ring 7 further fails, and the coolant leaks to the enclosed space between the fourth sealing gasket 9 and the second sealing ring 7. Due to the local incompressible property of the liquid, the pressure inside the enclosed space between the fourth sealing gasket 9 and the second sealing ring 7 increases rapidly, the pressure difference on both sides of the second sealing ring 7 returns to below the sealing threshold, and the second sealing ring 7 resumes its sealing function. Therefore, the addition of the fourth sealing gasket 9 provides a buffer space for the leakage of coolant caused by the pressure increase.

[0032] refer to Figure 6 , Figure 7 , Fig.10 and Fig.13As one embodiment, the adapter 5 is provided with a first bolt hole 5.3, the fourth gasket 9 is provided with a second bolt hole 9.1, and the cabinet wall 1 is provided with a third bolt hole 1.1. The first bolt hole 5.3, the second bolt hole 9.1 and the third bolt hole 1.1 are simultaneously threadedly connected by bolts to realize the connection between the adapter 5 and the cabinet wall 1 via the fourth gasket 9. In the case where it is inconvenient to replace the first gasket 6, the tightness between the first gasket 6 and the cabinet wall 1 is adjusted by adjusting the tightening degree of the bolts.

[0033] refer to Figure 3 , Figure 4 , Figure 5 and Fig.15 As one embodiment, the cross section of the second sealing ring 7 is O-shaped, that is, an O-ring. When the coolant pipeline 3 is inserted into the adapter 5, the second sealing ring 7 rolls in the first mounting groove 11 and also rolls along the inner surface 5.2 of the adapter 5 to prevent the second sealing ring 7 from being misplaced.

[0034] refer to Figure 3 , Figure 7 , Figure 8 , Fig. 9 and Fig.16 As one embodiment, the outer wall of the adapter 5 is in the shape of a pagoda, and the resistance of the external pipe to be inserted into the adapter 5 is smaller than the resistance of being pulled out from the adapter 5; the tower-shaped structure can effectively fit with the inner wall of the external pipe. Generally, by setting the maximum outer diameter of the pagoda of the adapter 5 to be slightly larger than the inner diameter of the external pipe to form an interference fit, and then locking it with a clamp, the connection point between the adapter 5 and the external pipe can be better sealed; Alternatively, the outer wall of the adapter 5 is provided with threads 5.6, and the external pipeline is connected to the adapter 5 via the threads.

[0035] These two connection methods can effectively reduce the probability of the external pipeline accidentally falling out of the adapter 5.

[0036] The coolant is usually an antifreeze liquid, and ethanol is used as a medium. In one embodiment, the second sealing ring 7 is made of EPDM rubber, nitrile rubber, polyurethane, silicone rubber, acrylate or thermoplastic dynamic vulcanized rubber to prevent corrosion by the coolant. As one embodiment, the other sealing pads can also be made of this material.

[0037] As one of the embodiments, the inner hole of the first sealing gasket 6 is interference fit with the outer wall of the coolant pipeline 3. When multiple sealing gaskets and sealing rings fail, the interference fit between the inner hole of the first sealing gasket 6 and the outer wall of the coolant pipeline 3 can further prevent the coolant from penetrating into the inner side of the cabinet wall 1.

[0038] refer to Fig. 9As one embodiment, the adapter 5 includes a first cavity 5.4 and a second cavity 5.5 whose inner diameter is smaller than that of the first cavity 5.4. The first cavity 5.4 and the second cavity 5.5 are connected by a first step 5.1. The first cavity 5.4 is used to fit with the coolant pipeline 3, and the second cavity 5.5 is used to communicate with the external pipeline.

[0039] The through-wall sealing structure of the pipeline provided in this embodiment, compared with the first embodiment, adds a fourth sealing gasket 9 to improve the sealing performance, and sets a first bolt hole 5.3, a second bolt hole 9.1 and a third bolt hole 1.1 to assist in adjusting the tightness between the first sealing gasket 6 and the cabinet wall 1, improve the installation flexibility, select the cross-section of the second sealing ring 7 to ensure that the position of the second sealing ring 7 will not be dislocated when the coolant pipeline 3 is inserted into the adapter 5, set the shape of the adapter 5, facilitate the reliable connection of the external pipeline, and provide a range of choices for the manufacturing material of the second sealing ring 7; improve the sealing ability, reduce the cost and component precision requirements.
