Technical Field

[0001] The utility model relates to a wall-penetrating sealing structure of a cabinet and a pipeline, belonging to the technical field of liquid cooling radiators. Background Art

[0002] The liquid-cooled radiator is installed on the cabinet wall. To dissipate heat, it exchanges coolant with the outside world through coolant pipes. Therefore, the coolant pipes are connected to external pipes after passing through the cabinet wall. The inlet and outlet of the coolant pipes are located on the cabinet wall. During use, some coolant may overflow from the pipe openings, while some may overflow into the cabinet wall, compromising safety within the cabinet.

[0003] There are two main existing solutions: 1. Filling the pipe surface accessories with expansion agent. 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, resulting in different expansion effects, which can easily cause coolant overflow; 2. Setting sealing grooves and sealing protrusions to cooperate with each other to achieve sealing, but this has high requirements for processing precision and is easily damaged during disassembly and assembly.

[0047] The following will be combined with the drawings in the present application / the present application's embodiments to clearly and completely describe the technical solutions of the present application / the present application's embodiments. Obviously, the described embodiments are only part of the embodiments of the present application / the present application, and not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present application / the present application, its application, or use. Example 1

[0048] This embodiment provides a pipeline wall-penetrating sealing structure to solve the problems of poor sealing performance and high requirements on machining accuracy of various components in the prior art pipeline wall-penetrating sealing structures.

[0049] refer to Figure 1 The liquid cooling radiator 2 is installed inside the cabinet wall 1, and is connected to the external pipeline through multiple cooling liquid pipes 3 through the preset perforations of the cabinet wall 1 to exchange cooling liquid. Therefore, its pipe opening surface 4 is outside the cabinet wall 1. The pipe wall sealing structure provided in this embodiment includes an adapter 5 for connecting the transition cooling liquid pipeline 3 with the external pipeline and preventing leakage; Figure 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 provided with a replaceable second sealing ring 7, and the flange surface 10 is further away from the pipe opening surface 4 of the coolant pipe 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, while the flange surface 10 is on the inside as one of the supports of the structure; Figure 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 pipe 3. It is worth noting that after the coolant pipe 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.

[0050] refer to Figure 1 、 Figure 2 and Figure 3When the coolant line 3 passes through the cabinet wall 1, it inserts into the adapter 5 and forms a clearance fit with the inner wall (or inner cavity) of the adapter 5. This clearance reduces the impact of dimensional mismatch between the inner cavity of the adapter 5 and the coolant line 3 caused by low machining precision (such as concentricity tolerance). The remaining clearance ensures that the coolant line 3 can be inserted into the adapter 5. The flange surface 10 and one side of the cabinet wall 1 are abutted against each other by a replaceable first sealing gasket 6. The adapter 5 is connected to the other side of the cabinet wall 1. By replacing the first sealing gasket 6 with an appropriate thickness, the tightness of the connection between the cabinet wall 1 and the flange surface 10 can be adjusted. The sealing performance is improved by selecting the most appropriate first sealing gasket 6 thickness. Because the coolant line 3 and the adapter 5 have a clearance fit, a second sealing ring 7 is required to seal the gap between the coolant line 3 and the adapter 5. At the same time, the nozzle surface 4 abuts against the first step 5.1 by a replaceable third sealing gasket 8 to prevent coolant leakage from the nozzle surface 4. Similar to the first sealing gasket 6, the second sealing ring 7 of the most suitable size can be replaced 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. The tightness between the pipe mouth surface 4 and the first step 5.1 can be adjusted by replacing the third sealing gasket 8 with the most suitable thickness.

[0051] During use, first apply the first sealing gasket 6 to the coolant line 3 and push it close to the flange surface 10. The coolant line 3 then extends through the pre-set perforation in the pipe wall 1, with the first mounting groove 11 located on the outside of the pipe wall 1, while the flange surface 10 is blocked on the inside of the pipe wall 1 by the perforation. A second sealing ring 7 is placed over the first mounting groove 11 to compensate for the concentricity tolerance between the outer diameter of the coolant line 3 and the inner surface 5.2. A third sealing gasket 8 is placed within the first step 5.1 of the adapter 5. After ensuring that both sides of the first sealing gasket 6 are in close contact with the flange surface 10 and the pipe wall 1, the adapter 5 is inserted into the coolant line 3 from the pipe opening surface 4 until the pipe opening surface 4 contacts the third sealing gasket 8. The thickness of the first sealing gasket 6 can be adjusted to find a size that effectively seals the perforation in the pipe wall 1, or the thickness of the third sealing gasket 8 can be adjusted to find a size that effectively seals the pipe opening surface 4. After finding the appropriate size, the pipe wall 1 and the adapter 5 are connected to fix the pipeline wall sealing structure on the pipe wall 1.

[0052] Connect the external pipe to the adapter 5, and input and output coolant to the liquid cooling radiator 2 to test the sealing degree.

[0053] 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 coolant pipeline 3 is ventilated to test the sealing ability of the second sealing ring 7, and the size that best suits the current manufacturing tolerance and gap is found through continuous replacement.

[0054] refer to Figure 3 Taking the output of coolant as an example, when in use, the coolant is input from the nozzle of the coolant pipeline 3 through the adapter 5 to the external pipeline. The third sealing gasket 8 seals the gap between the first step 5.1 and the nozzle surface 4 to prevent coolant leakage. 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 coolant leakage. If the second sealing ring 7 also fails, the coolant will spread further along the outer wall of the coolant pipeline 3 into the cabinet wall 1. Since the first sealing gasket 6 seals the gap between the flange surface 10 and the cabinet wall 1, it can prevent the coolant 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 it may leak out from the outside of the cabinet wall 1 through 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.

[0055] 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.

[0056] The through-wall sealing structure of the pipeline provided in this embodiment relaxes the precision requirements for component manufacturing and reduces manufacturing costs. 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, meeting 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, and the flange surface 10 serves as a support, and the coolant pipeline 3 is indirectly fixed to the cabinet wall 1 through the flexible extrusion action of the first sealing gasket 6, the second sealing ring 7 and the third sealing gasket 8, preventing the occurrence of stress deformation gaps and ensuring the sealing effect; therefore, it has considerable sealing ability and allows a gap between the adapter 5 and the coolant pipeline 3, adapting to lower manufacturing precision. Example 2

[0057] This embodiment provides a wall-penetrating sealing structure for a pipeline. This embodiment is optimized based on the first embodiment to improve the technical effect and refine the technical solution. For details not fully described in this embodiment, please refer to the first embodiment.

[0058] As one example, refer to Figure 3 、 Figure 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 the interval. The fourth sealing gasket 9 is used to seal the side of the adapter 5 close to the cabinet wall 1, forming three sealing lines from the third sealing gasket 8 to the second sealing ring 7 and then to the fourth sealing gasket 9.

[0059] 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, and 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 characteristics of the liquid, the pressure inside the enclosed space between the fourth sealing gasket 9 and the second sealing ring 7 rises rapidly, and 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 pressure increase.

[0060] refer to Figure 6 、 Figure 7 、 Figure 10 and Figure 13 In one embodiment, the adapter 5 defines a first bolt hole 5.3, the fourth gasket 9 defines a second bolt hole 9.1, and the cabinet wall 1 defines a third bolt hole 1.1. Bolts are simultaneously threadedly connected through the first bolt hole 5.3, the second bolt hole 9.1, and the third bolt hole 1.1 to connect the adapter 5 to the cabinet wall 1 via the fourth gasket 9. If replacement of the first gasket 6 is inconvenient, the tightness between the first gasket 6 and the cabinet wall 1 can be adjusted by adjusting the tightening of the bolts.

[0061] refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 15 As one embodiment, the cross-section of the second sealing ring 7 is O-shaped, that is, an O-ring. When the coolant pipe 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.

[0062] refer to Figure 3 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 16 As one embodiment, the outer wall of the adapter 5 is pagoda-shaped, and the resistance of the external pipe to inserting into the adapter 5 is smaller than the resistance to withdrawing from the adapter 5; the tower-shaped structure can effectively fit the inner wall of the external pipe. Generally, by setting the maximum outer diameter of the pagoda of the adapter 5 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;

[0063] 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.

[0064] These two connection methods can effectively reduce the probability of the external pipeline accidentally falling out of the adapter 5.

[0065] The coolant is usually antifreeze, with ethanol as the 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 gaskets can also be made of the same material.

[0066] As one embodiment, 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.

[0067] refer to Figure 9 As one embodiment, the adapter 5 includes a first cavity 5.4 and a second cavity 5.5 having an inner diameter 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.

[0068] The pipe wall sealing structure provided in this embodiment, compared with the first embodiment, adds a fourth sealing gasket 9 to improve the sealing performance, and provides 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, thereby improving installation flexibility. The cross-section of the second sealing ring 7 is selected 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. The shape of the adapter 5 is set to facilitate reliable connection of external pipelines, and a range of choices for the manufacturing material of the second sealing ring 7 is provided; thereby improving the sealing ability, reducing the cost and component precision requirements.

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 achieve the connection between the adapter 5 and the cabinet wall 1 via the fourth sealing gasket 9.

[0084] The cross section of the second sealing ring 7 is O-shaped. When the coolant pipe 3 is inserted into the adapter 5 , the second sealing ring 7 rolls along the inner surface 5 . 2 of the adapter 5 .
