Description

Testing agency

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on November 1, 2023, entitled “Testing Agency”. The application number of the prior application is 202311445223.4, and all the contents of the prior application are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of electronic equipment, and in particular to a detection mechanism. Background Art

[0003] As the performance of electronic devices continues to improve, the heat generated by the working components within them is also increasing. To cool these working components, liquid cooling devices are typically attached to the working components. The low-temperature liquid within the cooling device removes the heat from the working components, thereby cooling them.

[0004] Typically, a liquid cooling device includes a liquid cooling plate and a coolant pipeline. A flow channel for the coolant is provided in the liquid cooling plate. Two coolant pipelines are provided, both of which are connected to the coolant flow channel in the liquid cooling plate. One of the two coolant pipelines serves as a liquid inlet pipe and the other as a liquid outlet pipe to allow the coolant to circulate in the coolant flow channel.

[0005] However, during operation, liquid cooling devices may leak coolant due to poor sealing and other issues. Leaked coolant can drip onto working components and potentially damage them. Currently, to address this issue, some manufacturers wrap a leak detection wire around the liquid pipeline to form a liquid cooling device, which is used to detect coolant leaks. However, such liquid cooling devices can only detect coolant leaks in a certain direction and / or section of the pipeline. In other words, if a coolant leak occurs in an area not wrapped with the leak detection wire, the leaked coolant may not flow to the leak detection wire, resulting in low accuracy in detecting coolant leaks.

[0026] Furthermore, it also includes a recovery component, which is used to recover the cooling liquid;

[0027] One end of the leak-proof pipeline away from the shell is connected to a flow guide pipeline, and the first gap is connected to the recovery component through the flow guide pipeline.

[0052] The following will clearly and completely describe the technical solutions of this application in conjunction with the embodiments. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0053] As shown in Figures 1 to 6, an embodiment of the present application provides a detection mechanism, including: a shell 21 and a leak-proof pipeline 22; the shell 21 is used to cover the liquid cooling plate 11 of the liquid cooling device to be detected; the leak-proof pipeline 22 is used to be installed outside the cooling liquid pipeline 13 of the liquid cooling device to be detected, wherein the shell 21 and / or the leak-proof pipeline 22 are provided with a leakage detection sensor.

[0054] In this embodiment, a detection mechanism is applied to a liquid cooling device to detect whether there is a cooling liquid leak in the liquid cooling device. The liquid cooling device includes a liquid cooling plate 11 and a cooling liquid pipeline 13. The liquid cooling plate 11 is attached to the heating element. The liquid cooling plate 11 includes a base plate and a top plate. The base plate and the top plate are connected, and a cooling liquid flow channel for the cooling liquid to flow is formed between the base plate and the top plate. The liquid cooling plate 11 is provided with an interface 12 that connects the outside world with the cooling liquid flow channel. One end of the cooling liquid pipeline 13 is connected to this interface 12, and the other end is connected to the cooling liquid source, and is used to transport the cooling liquid back and forth between the cooling liquid source and the cooling liquid flow channel.

[0055] Optionally, the cooling liquid can be cooling water, or common cooling liquids, such as inorganic calcium chloride, organic methanol and ethanol.

[0056] In this embodiment, the detection mechanism consists of a housing 21 and a leak-proof pipe 22. The housing 21 is used to cover the liquid cooling plate 11, and the leak-proof pipe 22 is used to be installed outside the cooling liquid pipe 13. During assembly, one end of the cooling liquid pipe 13 is inserted into the leak-proof pipe 22 from the end of the leak-proof pipe 22 away from the housing 21. The end then passes through the leak-proof pipe 22 and extends into the interior of the housing 21, thereby connecting with the cooling plate 11. Cooling liquid in the external cooling liquid source can flow into the cooling plate 11 through the cooling liquid pipe 13 to cool the heating element.

[0057] In this embodiment, preferably, the leakage detection sensor is arranged inside the shell 21 and inside the anti-leakage pipeline 22, and the leakage detection sensor adopts a sheet-shaped sensor. The leakage detection sensor covers the inner wall of the entire shell 21 and the inner wall of the entire anti-leakage pipeline 22 to avoid missed detection, etc.

[0058] In this embodiment, a leakage detection sensor may be provided only on the housing 21, or only on the leak-proof pipe 22, or both on the housing 21 and the leak-proof pipe 22. In order to avoid the problem of missed detection, the latter is preferably adopted in this embodiment. In the detection mechanism provided in this embodiment, cooling liquid will flow inside the coolant pipe 13 and the liquid cooling plate 11 during use. By installing the leak-proof pipe 22 on the outside of the coolant pipe 13, when the coolant leaks, the cooling liquid will enter the leak-proof pipe 22; by covering the housing 21 on the liquid cooling plate 11, when the coolant leaks, the cooling liquid will be temporarily stored in the protective cavity 23. By providing the housing 21 and the leak-proof pipe 22, the leaked cooling liquid can be temporarily stored to prevent the leaked cooling liquid from dripping on the working element and causing damage to the working element.

[0059] Furthermore, a leakage detection sensor for detecting whether there is a cooling liquid leak is also provided within the housing 21 and / or the leak-proof pipeline 22. When a cooling liquid leak occurs in the liquid cooling plate 11, due to the provision of the housing 21, the leaked cooling liquid will only be temporarily stored within the housing 21 under the action of the housing 21 and will not flow around, allowing the leakage detection sensor within the housing 21 to promptly detect the cooling liquid leak. When a cooling liquid leak occurs in the cooling liquid pipeline 13, due to the provision of the leak-proof pipeline 22, the leaked cooling liquid will only be temporarily stored within the leak-proof pipeline 22 under the action of the leak-proof pipeline 22 and will not flow around, allowing the leakage detection sensor within the leak-proof pipeline 22 to promptly detect the cooling liquid leak. Compared to the prior art, any cooling liquid leak will be detected by the leakage detection sensor, resulting in more accurate detection results. The detection mechanism provided in this embodiment forms a first gap 24 between the leak-proof pipeline 22 and the cooling liquid pipeline 13, and the interior of the housing 21 is connected to the outside world through the first gap 24.

[0060] In this embodiment, after the housing 21 is provided, leaked cooling liquid will accumulate in the housing 21 . Long-term contact of the cooling liquid with the liquid cooling plate 11 and the housing 21 may corrode the liquid cooling plate 11 and the housing 21 , thereby shortening their service life.

[0061] To this end, in this embodiment, when the coolant pipeline 13 is assembled, a first gap 24 is formed between the outer wall of the coolant pipeline 13 and the inner wall of the leak-proof pipeline 22. Through this first gap 24, the cooling liquid leaked inside the shell 21 can be discharged from the shell 21 through the first gap 24, thereby avoiding the long-term accumulation of cooling liquid inside the shell 21.

[0062] In this embodiment, the coolant pipe 13 and the anti-leakage pipe 22 are both round pipes. In order to form the first gap 24 between the anti-leakage pipe 22 and the coolant pipe 13, the outer diameter of the coolant pipe 13 must be smaller than the inner diameter of the anti-leakage pipe 22.

[0063] The detection mechanism provided in this embodiment has a protective cavity 23 formed between the shell 21 and the liquid cooling plate 11, and the protective cavity 23 is connected to the outside world through the first gap 24; the liquid cooling plate 11 is provided with an interface 12 that connects the outside world with the interior of the liquid cooling plate 11, the interface 12 is located in the protective cavity 23, and the coolant pipeline 13 is connected to the interface 12.

[0064] In this embodiment, a coolant flow channel for circulating cooling liquid is formed within the liquid cooling plate 11. This S-shaped channel extends throughout the entire liquid cooling plate 11 to enhance the cooling effect of the liquid cooling plate 11. A port 12 is provided on the liquid cooling plate 11, connecting the cooling liquid flow channel to the outside world. A coolant line 13 is connected to this port. Because the primary location of coolant leakage from the liquid cooling plate 11 is at port 12, port 12 must be located within the protective cavity 23 to prevent leaked cooling liquid from reaching the heating element.

[0065] The housing 21 and the liquid-cooling plate 11 together form a protective cavity 23. This sealed cavity 23 is isolated from the outside world, preventing the cooling liquid from leaking out of it. During assembly, one end of the coolant line 13 is inserted through the leak-proof line 22, away from the housing 21, and then passed through the leak-proof line 22 into the protective cavity 23. The port of the coolant line 13 within the protective cavity 23 is connected to the interface 12, allowing the cooling liquid from the external cooling liquid source to flow into the liquid-cooling plate 11 through the coolant line 13.

[0066] As mentioned above, in this embodiment, the liquid cooling plate 11 comprises a base plate and a top plate. During use, the base plate is connected to the heating element, and the interface 12 is provided on the top plate. Accordingly, the housing 21 is also mounted on the top plate. In other words, the top plate and housing 21 together form a protective cavity 23.

[0067] In this embodiment, preferably, the leak-proof pipeline 22 is a hose, which can adapt to the coolant pipeline 13 with different bending forms.

[0068] In this embodiment, the housing 21 is in a groove-shaped structure with one end open. During assembly, the open end is connected to the top plate.

[0069] The detection mechanism provided in the embodiment of the present application forms a protective cavity 23 by connecting the shell 21 to the liquid cooling plate 11, and protects the interface 12 in the protective cavity 23. When the cooling liquid leaks at the interface 12, the cooling liquid will be temporarily stored in the protective cavity 23 and will not affect the heating element. Furthermore, since a leak-proof pipeline 22 is provided that is sleeved outside the cooling liquid pipeline 13, and a first gap 24 is formed between the leak-proof pipeline 22 and the cooling liquid pipeline 13, the cooling liquid leaked into the protective cavity 23 can also flow out of the protective cavity 23 through the first gap 24, which can prevent the cooling liquid from affecting the service life of the shell 21 and the heating element, cooling liquid pipeline 13 and liquid cooling plate 11 in the shell 21. It can effectively prevent the heating element from being damaged due to leakage of the liquid cooling plate 11. Moreover, after the liquid cooling plate 11 is combined with the detection mechanism of this embodiment, even if the liquid cooling plate 11 leaks, it will not be stored in the protective cavity 23, and there is no need to shut down the equipment for processing, so that the equipment using the heating element can be operated without stopping.

[0070] In this embodiment, the liquid cooling plate 11 can be used in server scenarios such as a CPU (central processing unit) or a graphics card.

[0071] In this embodiment, the interface 12 can be a common elbow with a pagoda connector on the market, and is connected to the pagoda connector at the end of the coolant pipeline 13.

[0072] Optionally, in this embodiment, the material of the shell 21 can be any one of PBT (polybutylene terephthalate), PFA (tetrafluoroethylene-perfluoroalkoxy vinyl ether copolymer), PE (polyethylene), PP (polypropylene), PTFE (polytetrafluoroethylene), FEP (perfluoroethylene propylene copolymer) and PEEK (polyetheretherketone).

[0073] In this embodiment, when liquid leakage detection sensors are provided in both the leak-proof pipeline 22 and the housing 21 , “double insurance” detection can be achieved.

[0074] For the convenience of description, the liquid leakage detection sensor in the housing 21 is a first liquid leakage detection sensor, and the liquid leakage detection sensor in the anti-leakage pipeline 22 is a second liquid leakage detection sensor.

[0075] Specifically, suppose the first leakage detection sensor malfunctions. In this case, the first leakage detection sensor is unable to promptly alert the operator of a cooling liquid leak within the protective cavity 23. However, due to the first gap 24 and the second detection function, when the cooling liquid flows to the second leakage detection sensor, the second leakage detection sensor detects liquid flow within the anti-leakage pipeline 22, effectively alerting the operator of a cooling liquid leak within the liquid cooling plate 11, allowing the operator to promptly address the issue.

[0076] At the same time, the second liquid leakage detection sensor cooperates with the first liquid leakage detection sensor to remind technical personnel whether there is blockage in the leak-proof pipeline 22.

[0077] The detection mechanism provided in the embodiment of the present application is shown in Figures 1 to 5, and a through hole is opened on the side wall of the shell 21; the coolant pipeline 13 extends through the through hole into the interior of the shell 21 and is connected with the liquid cooling plate 11, and a second gap 25 is formed between the coolant pipeline 13 and the through hole; the leak-proof pipeline 22 is connected to the outer edge of the through hole, and the first gap 24 is connected with the interior of the shell 21 through the second gap 25.

[0078] In this embodiment, a through-hole is provided in the sidewall of the housing 21, through which the coolant line 13 extends into the interior of the housing 21, specifically into the protective cavity 23. Furthermore, the inner diameter of the through-hole is larger than the outer diameter of the coolant line 13, thereby forming the second gap 25 between the coolant line 13 and the through-hole. The first gap 24 between the leak-proof line 22 and the coolant line 13 communicates with the protective cavity 23 via the second gap 25 between the through-hole and the leak-proof line 22.

[0079] Optionally, the inner edge of the leak-proof pipe 22 is connected to the outer edge of the through hole to prevent the second gap 25 from being too small when the leak-proof pipe 22 is plugged into the through hole, thereby affecting the discharge of cooling liquid through the second gap 25.

[0080] In this embodiment, the through hole is provided to communicate with the leak-proof pipeline 22, so the structure is simple and the manufacturing is convenient.

[0081] Optionally, a notch or other structure may be provided on the housing 21 so that the coolant pipeline 13 can extend into the housing 21 and the first gap 24 can communicate with the protective cavity 23 .

[0082] Furthermore, in this embodiment, to facilitate the connection between the housing 21 and the leak-proof pipeline 22, a connecting portion 213 specifically for connection to the leak-proof pipeline 22 is provided on the housing 21. The connecting portion 213 corresponds to the through-holes, i.e., each through-hole is provided with a connecting portion 213. A channel 214 is defined in the connecting portion 213, which communicates with the through-holes, i.e., the channel 214 connects the inside and outside of the housing 21. The connecting portion 213 is connected to the leak-proof pipeline 22. Optionally, the connection between the connecting portion 213 and the leak-proof pipeline 22 can be a snap-on, plug-in, or threaded connection.

[0083] In this embodiment, after the leak-proof pipeline 22 and the connecting portion 213 are assembled, the coolant pipeline 13 extends through the channel 214 into the interior of the housing 21, specifically into the protective cavity 23. The second gap 25 has two sections: one between the through hole and the coolant pipeline 13, and the other between the outer wall of the coolant pipeline 13 and the inner wall of the channel 214. The first gap 24 communicates with the protective cavity 23 through the second gap 25.

[0084] That is, when the detection mechanism is assembled, the leak-proof pipeline 22, the channel 214, the through hole and the interior of the housing 21 are connected in sequence.

[0085] When the coolant pipeline 13 is assembled, the end of the coolant pipeline 13 passes through the leak-proof pipeline 22 , the channel 214 and the through hole in sequence and then extends into the housing 21 .

[0086] In this embodiment, the height of the leakage-proof pipe 22 at the end away from the shell 21 can be set lower, and the height at the end close to the shell 21 can be set higher, so as to facilitate the cooling liquid leaking in the protection cavity 23 to be discharged.

[0087] For example, a through hole and other structures are provided on the side wall of the shell 21 opposite to the ground, and this side wall is provided horizontally, and then the leak-proof pipeline 22 is provided vertically.

[0088] Furthermore, a structure such as a drainage slope for guiding the cooling liquid to the through hole may be provided in the housing 21 to facilitate the discharge of leaked cooling liquid.

[0089] Optionally, as shown in FIG. 3 , the connecting portion 213 is a cylindrical joint, and the cylindrical joint is inserted into the leak-proof pipeline 22 .

[0090] In this embodiment, the connecting portion 213 is a cylindrical joint corresponding to the leak-proof pipeline 22 , and the leak-proof pipeline 22 and the cylindrical joint are plug-connected. Specifically, the cylindrical joint is inserted into the leak-proof pipeline 22 .

[0091] In this embodiment, the connecting portion 213 is configured as a cylindrical joint, which can facilitate the assembly of the leak-proof pipeline 22 and the connecting portion 213 by the operator compared to square, elliptical and other structures. In addition, the cylindrical joint is easy to process and is mostly a standard part with low cost.

[0092] The detection mechanism provided in the embodiment of the present application is sealed between the leak-proof pipeline 22 and the connecting portion 213 to ensure that the cooling liquid in the protective cavity 23 does not leak from the connection between the leak-proof pipeline 22 and the connecting portion 213 when the cooling liquid is transported outward.

[0093] Optionally, the leak-proof pipeline 22 may be a common hose, which may be sealed by providing a structure such as a sealing ring or sealant at the connection.

[0094] Optionally, the leak-proof pipeline 22 may also be a heat shrink tube. After the connecting portion 213 is inserted into the leak-proof pipeline 22, the connection strength between the leak-proof pipeline 22 and the connecting portion 213 is improved by heating, and sealing can also be achieved.

[0095] By sealing the leak-proof pipeline 22 and the connecting portion 213, the cooling liquid leaked in the protective cavity 23 can be prevented from leaking out from between the leak-proof pipeline 22 and the connecting portion 213, so that the cooling liquid leaked in the protective cavity 23 can only flow into the subsequent recovery component.

[0096] The detection mechanism provided in the embodiment of the present application is shown in Figures 1 to 5, and the shell 21 includes a frame 211 and a cover plate 212; one end of the frame 211 is connected to the cover plate 212, and the other end is connected to the liquid cooling plate 11. When the shell 21 is mounted on the liquid cooling plate 11, the liquid cooling plate 11, the frame 211 and the cover plate 212 together form the protective cavity 23.

[0097] In this embodiment, the housing 21 is divided into two parts, namely a frame 211 and a cover plate 212. The frame 211 can be a square frame or a circular frame, and the specific shape can be selected according to actual conditions.

[0098] In this embodiment, one end of the frame 211 is connected to the cover plate 212 to form the above-mentioned groove-shaped structure, and the other end of the frame 211 is connected to the top plate of the liquid cooling plate 11. The top plate of the liquid cooling plate 11, the frame 211 of the shell 21 and the cover plate 212 of the shell 21 together form the protective cavity 23.

[0099] In this embodiment, the housing 21 is composed of a frame 211 and a cover 212. Its structure is simple, easy to manufacture, and low in cost. Furthermore, the size of the frame 211 can be adjusted to the size of the liquid cooling plate 11, making the connection between the housing 21 and the liquid cooling plate 11 more stable.

[0100] In the detection mechanism provided in the embodiment of the present application, optionally, the frame 211 and the cover plate 212 are an integrated structure, and a seal is provided between the frame 211 and the liquid cooling plate 11 .

[0101] In this embodiment, the frame 211 and the cover plate 212 may be an integral structure, that is, the housing 21 is integrally formed, which has high manufacturing efficiency. At the same time, the frame 211 and the cover plate 212 are sealed by integral molding.

[0102] In this embodiment, in order to improve the sealing of the protective cavity 23, a sealing structure is provided between the frame 211 and the liquid cooling plate 11, specifically, between the frame 211 and the top plate. The sealing structure can be a sealing ring or sealant provided between the frame 211 and the top plate.

[0103] In this embodiment, the frame 211 and the top plate are connected by bolts, and the bolts can also tighten the sealing ring to improve the airtightness of the protective cavity 23.

[0104] In the detection mechanism provided in the embodiment of the present application, optionally, the frame 211 and the cover plate 212 are separate structures, and a seal is provided between the frame 211 and the cover plate 212 , and between the frame 211 and the liquid cooling plate 11 .

[0105] In this embodiment, the frame 211 and the cover 212 are separate structures, which can be connected by structures such as bolts. When the frame 211 or the cover 212 is damaged, one of them can be replaced separately, which is convenient for technicians to repair and maintain.

[0106] In this embodiment, to improve the airtightness of the protective cavity 23, a seal is provided between the frame 211 and the cover plate 212, as well as between the frame 211 and the top plate. Alternatively, a sealing ring or the like may be provided between the frame 211 and the cover plate 212, as well as between the frame 211 and the top plate, or a sealant or the like may be applied.

[0107] In this embodiment, the frame 211 and the top plate, as well as the frame 211 and the cover plate 212 are connected by bolts.

[0108] The detection mechanism provided in the embodiment of the present application, as shown in Figure 6, also includes a recovery component; the end of the leak-proof pipeline 22 away from the shell 21 is connected to a guide pipeline 26, and the first gap 24 is connected to the recovery component through the guide pipeline 26.

[0109] In this embodiment, a branch is branched off from the end of the leak-proof pipeline 22 away from the shell 21, and the branch is the guide pipeline 26. The guide pipeline 26 is connected to the leak-proof pipeline 22. When the coolant pipeline 13 is installed into the leak-proof pipeline 22, a first gap 24 is formed between the leak-proof pipeline 22 and the coolant pipeline 13, and the first gap 24 is connected to the guide pipeline 26.

[0110] In this embodiment, the recovery assembly can be a recovery barrel or waste liquid tank, etc., which is used to recover leaked cooling liquid. The leak-proof pipe 22 is connected to the recovery assembly via a diversion pipe 26. Cooling liquid leaking into the protective cavity 23 and / or the first gap 24 flows into the recovery assembly through the diversion pipe 26, thereby preventing the leaked cooling liquid from harming external devices or the environment and reducing losses.

[0111] In the detection mechanism provided in the embodiment of the present application, generally, the liquid cooling plate 11 has two interfaces 12 , and accordingly, the detection mechanism includes two leak-proof pipelines 22 , and two of the aforementioned connecting portions 213 are provided on the housing 21 .

[0112] In this embodiment, when the liquid cooling plate 11 is in use, multiple liquid cooling plates 11 may be connected in series. Taking two liquid cooling plates 11 as an example, the two liquid cooling plates 11 have three cooling liquid pipelines 13, one of which serves as a liquid inlet pipeline and is connected to the interface 12 on one of the liquid cooling plates 11, another serves as a liquid outlet pipeline and is connected to the interface 12 on the other liquid cooling plate 11, and the remaining cooling liquid pipeline 13 has its ends connected to the remaining interfaces 12 on the two liquid cooling plates 11.

[0113] Correspondingly, the detection mechanism includes two shells 21 and three leak-proof pipelines 22. The three leak-proof pipelines 22 correspond to the three coolant pipelines 13. The two shells 21 are respectively covered on the two liquid cooling plates 11, and the three leak-proof pipelines 22 are respectively sleeved on the corresponding coolant pipelines 13.

[0114] Furthermore, since the housing 21 is at the lowest position of the entire body when the liquid cooling device of the server is installed, liquid will accumulate in the housing 21 when leaking. Therefore, a liquid leakage detection sensor is arranged inside the housing 21.

[0115] For a dual-core server, the structure is to connect two liquid cooling plates 11 in series between three sections of pipes. The leakage detection sensor in the cold plate housing 21 is connected in series or in parallel through a signal transmission line placed between the leak-proof sleeve and the liquid cooling pipe. When the signal transmission line is installed, the electrode enters the housing 21 through the gap between the inner wall of the step hole and the liquid cooling pipe. When leakage occurs, it detects leakage and issues an alarm.

[0116] In this way, when the coolant pipeline 13 of the liquid cooling plate 11 leaks, it will be quickly identified and alarmed by the leakage detection sensor, and the leakage will be blocked by the second-layer leak-proof structure and diverted to the outside of the server. The leaked liquid can be connected to the recovery component through the coolant pipeline 13 in the server for leakage recovery to avoid harming external devices or the environment and reduce losses. At the same time, the server can run without stopping for a short time to ensure data security.
