In order to cool the working components, a liquid cooling device is generally attached to the outside of the working components, and the low-temperature liquid in the liquid cooling device takes away the heat of the working components to cool the working components.

[0003] Typically, a liquid cooling device includes a liquid cooling plate and a coolant pipeline. A flow channel for the flow of 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 an inlet pipe and the other as an outlet pipe, so that the coolant circulates in the coolant flow channel.

[0004] However, when the liquid cooling device is working, due to problems such as poor sealing, there may be coolant leakage, and the leaked coolant dripping on the working components may cause damage to the working components. At present, in order to solve the above problems, some manufacturers will wrap a leak detection wire around the liquid pipeline to form a liquid cooling device, which is used to detect the leakage of coolant, but such a liquid cooling device can only detect the leakage of coolant in a certain direction and / or a certain section of the pipeline, that is, when the coolant leaks in the area where the leak detection wire is not wrapped, the leaked coolant may not flow to the leak detection wire, resulting in low accuracy in detecting the leakage of coolant.

[0040] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] like Figures 1 to 6 As shown, an embodiment of the present invention 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 mounted on the outside of 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.

[0042] In this embodiment, the detection mechanism is applied to the 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 is connected to the top plate, and a cooling liquid flow channel for cooling liquid to flow is formed between the base plate and the top plate. An interface 12 connecting the outside world with the cooling liquid flow channel is provided on the liquid cooling plate 11. 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.

[0043] Optionally, the cooling liquid can be cooling water, or common cooling liquids such as inorganic calcium chloride, organic methanol and ethanol.

[0044] In this embodiment, the detection mechanism is composed of a shell 21 and a leak-proof pipeline 22. The shell 21 is used to cover the liquid cooling plate 11, and the leak-proof pipeline 22 is used to be sleeved outside the cooling liquid pipeline 13. During assembly, one end of the cooling liquid pipeline 13 is inserted into the leak-proof pipeline 22 from the end of the leak-proof pipeline 22 away from the shell 21, and then passes through the leak-proof pipeline 22 and extends into the interior of the shell 21, and is connected with the liquid cooling plate 11. The cooling liquid in the external cooling liquid source can flow into the liquid cooling plate 11 through the cooling liquid pipeline 13 to cool the heating element.

[0045] 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.

[0046] In this embodiment, a leakage detection sensor may be provided only on the housing 21, or only on the leak-proof pipeline 22, or both on the housing 21 and the leak-proof pipeline 22. In order to avoid the problem of missed detection, the latter is preferably used in this embodiment. In the detection mechanism provided in this embodiment, cooling liquid will flow inside the coolant pipeline 13 and the liquid cooling plate 11 during use. By installing the leak-proof pipeline 22 on the outside of the coolant pipeline 13, when the cooling liquid leaks in the coolant pipeline 13, the cooling liquid will enter the leak-proof pipeline 22; by covering the housing 21 on the liquid cooling plate 11, when the cooling liquid leaks in the liquid cooling plate 11, the cooling liquid will be temporarily stored in the protective cavity 23. By providing the housing 21 and the leak-proof pipeline 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.

[0047] Furthermore, a leakage detection sensor for detecting whether there is a cooling liquid leak is also provided in the shell 21 and / or the leak-proof pipeline 22. When the cooling liquid leaks in the liquid cooling plate 11, due to the provision of the shell 21, under the action of the shell 21, the leaked cooling liquid will only be temporarily stored in the shell 21, and will not flow around, so that the leakage detection sensor in the shell 21 can detect the cooling liquid leak in time. When the cooling liquid leaks in the cooling liquid pipeline 13, due to the provision of the leak-proof pipeline 22, under the action of the leak-proof pipeline 22, the leaked cooling liquid will only be temporarily stored in the leak-proof pipeline 22, and will not flow around, so that the leakage detection sensor in the leak-proof pipeline 22 can detect the cooling liquid leak in time. Compared with the prior art, as long as the cooling liquid leaks, it will be detected by the leakage detection sensor, so that the detection result is more accurate. 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 shell 21 is connected to the outside through the first gap 24.

[0048] In this embodiment, after the shell 21 is provided, leaked cooling liquid will accumulate in the shell 21. Long-term contact of the cooling liquid with the liquid cooling plate 11 and the shell 21 may corrode the liquid cooling plate 11 and the shell 21, thus affecting the service life of both.

[0049] 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.

[0050] In this embodiment, the coolant pipeline 13 and the leak-proof pipeline 22 are both round tubes. In order to form the first gap 24 between the leak-proof pipeline 22 and the coolant pipeline 13, the outer diameter of the coolant pipeline 13 must be smaller than the inner diameter of the leak-proof pipeline 22.

[0051] The detection mechanism provided in this embodiment, the shell 21 and the liquid cooling plate 11 enclose a protective cavity 23, 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 connecting the outside world with the inside 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.

[0052] In this embodiment, a cooling liquid flow channel for circulating cooling liquid is formed in the liquid cooling plate 11. The cooling liquid flow channel is an S-shaped flow channel, which covers the entire liquid cooling plate 11 to improve the cooling effect of the liquid cooling plate 11. The liquid cooling plate 11 is provided with an interface 12 for connecting the outside world with the cooling liquid flow channel, and the cooling liquid pipeline 13 is connected to the interface 12. Since the main location of cooling liquid leakage at the liquid cooling plate 11 is the interface 12, it is necessary to ensure that the interface 12 is located in the protective cavity 23 to prevent the leaked cooling liquid from flowing to the heating element.

[0053] The shell 21 and the liquid cooling plate 11 together enclose a protective cavity 23, which is sealed, that is, the protective cavity 23 is not connected to the outside world, and can prevent the cooling liquid from leaking from the protective cavity 23 to the outside world. During assembly, one end of the cooling liquid pipeline 13 is inserted into the leakage-proof pipeline 22 from the end of the leakage-proof pipeline 22 away from the shell 21, and then passes through the leakage-proof pipeline 22 and extends into the protective cavity 23. The port of the cooling liquid pipeline 13 located in the protective cavity 23 is connected to the interface 12, and the cooling liquid in the external cooling liquid source can flow into the liquid cooling plate 11 through the cooling liquid pipeline 13.

[0054] In this embodiment, as mentioned above, the liquid cooling plate 11 includes a base plate and a top plate. When in use, the base plate is connected to the heating element, and the interface 12 is arranged on the top plate. Correspondingly, the shell 21 is also covered on the top plate, that is, the top plate and the shell 21 together form a protective cavity 23.

[0055] In this embodiment, preferably, the leak-proof pipeline 22 is a hose, which can adapt to the coolant pipeline 13 with different bending forms.

[0056] In this embodiment, the housing 21 is in a groove-shaped structure, one end of which is open. During assembly, the open end is connected to the top plate.

[0057] The detection mechanism provided in the embodiment of the present invention forms a protective cavity 23 by connecting the shell 21 with 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 also provided 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 cooperates with the detection mechanism in 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.

[0058] 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.

[0059] In this embodiment, the interface 12 may be an elbow with a pagoda joint commonly found on the market, and is connected to the pagoda joint at the end of the coolant pipeline 13 .

[0060] 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).

[0061] In this embodiment, after the leakage detection sensors are arranged in both the leakage-proof pipeline 22 and the housing 21, "double insurance" detection can also be achieved.

[0062] 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.

[0063] Specifically, suppose that the first liquid leakage detection sensor fails. At this time, the first liquid leakage detection sensor cannot promptly remind the technician that the cooling liquid in the protective cavity 23 is leaking. However, under the action of the first gap 24 and the second detection, when the cooling liquid flows to the second liquid leakage detection sensor, the second liquid leakage detection sensor detects that there is liquid flowing in the anti-leakage pipeline 22, and can still promptly remind the operator to find that the cooling liquid in the liquid cooling plate 11 is leaking, so that the technician can handle it in time.

[0064] At the same time, the cooperation between the second liquid leakage detection sensor and the first liquid leakage detection sensor can also remind the technicians whether the anti-leakage pipeline 22 is blocked.

[0065] The detection mechanism provided by the embodiment of the present invention is as follows: Figures 1 to 5 As shown, 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.

[0066] In this embodiment, a through hole is provided on the side wall of the housing 21, and the coolant pipeline 13 can extend into the interior of the housing 21, specifically into the protective cavity 23 through the through hole. In addition, the inner diameter of the through hole is larger than the outer diameter of the coolant pipeline 13, so that the second gap 25 can be formed between the coolant pipeline 13 and the through hole. The first gap 24 between the leak-proof pipeline 22 and the coolant pipeline 13 is connected to the protective cavity 23 through the second gap 25 between the through hole and the leak-proof pipeline 22.

[0067] Optionally, the inner edge of the leak-proof pipeline 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 pipeline 22 is plugged into the through hole, thereby affecting the discharge of cooling liquid through the second gap 25 .

[0068] 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.

[0069] Optionally, a notch or other structure may be provided on the shell 21 so that the coolant pipeline 13 can extend into the shell 21 and the first gap 24 can communicate with the protection cavity 23 .

[0070] Further, in this embodiment, in order to facilitate the connection between the housing 21 and the leak-proof pipeline 22, a connecting portion 213 specifically used for connecting to the leak-proof pipeline 22 is provided on the housing 21. The connecting portion 213 corresponds to the through hole, that is, each through hole is provided with the connecting portion 213. A channel 214 is provided on the connecting portion 213, and the channel 214 is connected to the through hole, that is, the channel 214 is connected to the inside and outside of the housing 21. The connecting portion 213 is connected to the leak-proof pipeline 22. Optionally, the connecting portion 213 and the leak-proof pipeline 22 can be connected by a snap connection, a plug connection, or a threaded connection.

[0071] In this embodiment, after the leak-proof pipeline 22 and the connecting portion 213 are assembled, the coolant pipeline 13 passes through the channel 214 and extends into the interior of the housing 21, specifically into the protective cavity 23. The second gap 25 has two sections, one section is between the through hole and the coolant pipeline 13, and the other section is between the outer wall of the coolant pipeline 13 and the inner wall of the channel 214. The first gap 24 is connected to the protective cavity 23 through the second gap 25.

[0072] 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.

[0073] 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 .

[0074] In this embodiment, the height of the end of the leak-proof pipeline 22 away from the shell 21 can be set lower, and the shell 21 can be set higher, so that the cooling liquid leaked in the protection cavity 23 is discharged outward.

[0075] For example, structures such as through holes are arranged on the side wall of the shell 21 opposite to the ground, and this side wall is arranged horizontally, and then the leak-proof pipeline 22 is arranged vertically.

[0076] Furthermore, a drainage slope or other structure for guiding the cooling liquid to the through hole may be provided in the housing 21 to facilitate the leakage of the cooling liquid.

[0077] Optional, such as Figure 3 As shown, the connecting portion 213 is a cylindrical joint, and the cylindrical joint is inserted into the leak-proof pipeline 22.

[0078] In this embodiment, the connection 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 .

[0079] In this embodiment, the connection part 213 is set as a cylindrical joint. Compared with square, elliptical and other structures, it is convenient for operators to assemble the leak-proof pipeline 22 and the connection part 213. In addition, the cylindrical joint is easy to process and is mostly a standard part with low cost.

[0080] The detection mechanism provided in the embodiment of the present invention is provided with a sealing arrangement 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.

[0081] 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 a sealant at the connection.

[0082] 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 increased by heating, and sealing can also be achieved.

[0083] By sealing the leak-proof pipeline 22 and the connecting portion 213, the cooling liquid leaking from 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 leaking from the protective cavity 23 can only flow into the subsequent recovery component.

[0084] The detection mechanism provided by the embodiment of the present invention is as follows: Figures 1 to 5 As shown, 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 sleeved 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.

[0085] 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, which can be selected according to actual conditions.

[0086] 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.

[0087] In this embodiment, the housing 21 is composed of a frame 211 and a cover plate 212. The structure is simple, easy to manufacture, and low in cost. In addition, the size of the frame 211 can be set according to the size of the liquid cooling plate 11, so that the connection between the housing 21 and the liquid cooling plate 11 is more stable.

[0088] In the detection mechanism provided in the embodiment of the present invention, optionally, the frame 211 and the cover plate 212 are an integrated structure, and the frame 211 and the liquid cooling plate 11 are sealed.

[0089] 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 a high manufacturing efficiency. Meanwhile, the frame 211 and the cover plate 212 are sealed by integrally forming.

[0090] 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 may be a sealing ring, or a sealant, etc., provided between the frame 211 and the top plate.

[0091] In this embodiment, the frame 211 is connected to the top plate by bolts, and the bolts can also tighten the sealing ring to improve the airtightness of the protection cavity 23.

[0092] In the detection mechanism provided in the embodiment of the present invention, optionally, the frame 211 and the cover plate 212 are separate structures, and the frame 211 and the cover plate 212 are sealed, as well as the frame 211 and the liquid cooling plate 11 are sealed.

[0093] In this embodiment, the frame 211 and the cover plate 212 are separate structures, and the two can be connected by structures such as bolts. When the frame 211 or the cover plate 212 is damaged, one of them can be replaced separately, which is convenient for technicians to repair and maintain.

[0094] In this embodiment, in order to improve the airtightness of the protective cavity 23, a seal is set between the frame 211 and the cover plate 212, and between the frame 211 and the top plate. Optionally, a sealing ring or the like can be set between the frame 211 and the cover plate 212, and between the frame 211 and the top plate, or a sealant or the like can be applied.

[0095] 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.

[0096] The detection mechanism provided by the embodiment of the present invention is as follows: Figure 6 As shown, a recovery component is also included; 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.

[0097] In this embodiment, a branch is formed at one 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.

[0098] In this embodiment, the recovery component can be a recovery barrel or a waste liquid pool, etc., which is used to recover the leaked cooling liquid. The anti-leakage pipeline 22 is connected to the recovery component through the guide pipeline 26, and the cooling liquid leaked into the protection cavity 23 and / or the first gap 24 flows into the recovery component through the guide pipeline 26, so as to prevent the leaked cooling liquid from harming the external device or the environment and reduce the loss.

[0099] In the detection mechanism provided in the embodiment of the present invention, usually, the liquid cooling plate 11 has two interfaces 12 , and correspondingly, the detection mechanism includes two leak-proof pipelines 22 , and two connecting parts 213 are provided on the shell 21 .

[0100] In this embodiment, when the liquid cooling plate 11 is in use, there may be a situation where multiple liquid cooling plates 11 are 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 is used as a liquid inlet pipeline and is connected to the interface 12 on one of the liquid cooling plates 11, and the other is used as a liquid outlet pipeline and is connected to the interface 12 on the other liquid cooling plate 11. The two ends of the remaining cooling liquid pipeline 13 are connected to the remaining interfaces 12 on the two liquid cooling plates 11.

[0101] 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 outside the corresponding coolant pipelines 13 .

[0102] Furthermore, since the housing 21 is at the lowest position as a whole when the liquid cooling device of the server is installed, liquid will accumulate in the housing 21 when leakage occurs, and therefore a liquid leakage detection sensor is arranged inside the housing 21 .

[0103] For a two-way server, its structure is that two liquid cooling plates 11 are connected in series between three sections of pipelines. The leakage detection sensor in the cold plate shell 21 is connected in series or in parallel through the signal transmission line placed between the leak-proof sleeve and the liquid cooling pipeline. When the signal transmission line is installed, the electrode enters the shell 21 from the gap between the inner wall of the step hole and the liquid cooling pipeline. When leakage occurs, the leakage is detected and an alarm is issued;

[0104] In this way, when leakage occurs in the coolant pipeline 13 of the liquid cooling plate 11, the leakage detection sensor will quickly identify and alarm, and the leakage will be blocked by the two-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 to recover the leaked liquid to avoid harming external devices or the environment and reduce losses. At the same time, the server can run without stopping for a short period of time to ensure data security.
