Detailed Description

The technical solutions of the present utility model will be clearly and completely described in connection with the embodiments, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 to 6, one embodiment of the present utility model provides a detection mechanism including: a housing 21 and a leak-proof pipe 22; the shell 21 is used for being covered on the liquid cooling plate 11 of the liquid cooling device to be detected; the leakage-proof pipeline 22 is used for being sleeved outside the cooling liquid pipeline 13 of the liquid cooling device to be detected, wherein the shell 21 and/or the leakage-proof pipeline 22 are/is provided with a leakage detection sensor.

In this embodiment, the detection mechanism is applied to the liquid cooling device and is used for detecting whether the liquid cooling device has cooling liquid leakage. The liquid cooling device comprises a liquid cooling plate 11 and a cooling liquid pipeline 13, wherein the liquid cooling plate 11 is attached to the heating element, the liquid cooling plate 11 comprises a base plate and a top plate, the base plate is connected with the top plate, and a cooling liquid flow channel for 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 for communicating the outside with the cooling liquid flow passage. A coolant line 13 communicates at one end with this interface 12 and at the other end with a source of cooling liquid for reciprocating the cooling liquid between the source of cooling liquid and the coolant flow passage.

Alternatively, the cooling liquid may be cooling water, or common cooling liquid such as inorganic calcium chloride, organic methanol, ethanol, etc.

In this embodiment, the detection mechanism is composed of a housing 21 and a leakage-proof pipe 22. The shell 21 is used for covering the liquid cooling plate 11, the leakage-proof pipeline 22 is used for being sleeved outside the cooling liquid pipeline 13, one end of the cooling liquid pipeline 13 penetrates the leakage-proof pipeline 22 from one end of the leakage-proof pipeline 22 away from the shell 21 during assembly, then penetrates out of the leakage-proof pipeline 22 and stretches into the shell 21 and is communicated with the liquid cooling plate 11, and cooling liquid in an external cooling liquid source can flow into the liquid cooling plate 11 through the cooling liquid pipeline 13 so as to cool the heating element.

In the present embodiment, it is preferable that the leak detection sensor is provided inside the housing 21 and inside the leak-proof pipe 22, and that the leak detection sensor be a sheet-like sensor that covers the inner wall of the entire housing 21 and the inner wall of the entire leak-proof pipe 22 to avoid occurrence of leak detection or the like.

In the present embodiment, the leakage detection sensor may be provided only in the case 21, the leakage detection sensor may be provided only in the leakage prevention pipe 22, or the leakage detection sensor may be provided in both the case 21 and the leakage prevention pipe 22, and in order to avoid the problem of leakage detection, the latter is preferably used in the present embodiment. In the detection mechanism provided in this embodiment, during use, the cooling liquid flows through the cooling liquid pipe 13 and the liquid cooling plate 11. By sheathing the leakage-proof pipeline 22 outside the cooling liquid pipeline 13, when the cooling liquid leakage occurs in the cooling liquid pipeline 13, the cooling liquid can enter the leakage-proof pipeline 22; when the liquid cooling plate 11 leaks by covering the liquid cooling plate 11 with the casing 21, the cooling liquid is temporarily stored in the protection chamber 23. By arranging the shell 21 and the leakage-proof pipeline 22, leaked cooling liquid can be temporarily stored, and the working element damage caused by the fact that the leaked cooling liquid drops on the working element is avoided.

Further, a leakage detection sensor for detecting whether or not the cooling liquid is leaked is provided in the casing 21 and/or the leakage prevention pipe 22. When the liquid cooling plate 11 leaks cooling liquid, due to the shell 21, the leaked cooling liquid is only temporarily stored in the shell 21 and does not flow everywhere under the action of the shell 21, so that the leakage detection sensor in the shell 21 can timely detect the leakage of the cooling liquid. When the cooling liquid leaks from the cooling liquid pipeline 13, due to the leakage-proof pipeline 22, the leaked cooling liquid can only be temporarily stored in the leakage-proof pipeline 22 and cannot flow everywhere under the action of the leakage-proof pipeline 22, so that the leakage detection sensor in the leakage-proof pipeline 22 can timely detect the leakage of the cooling liquid. Compared with the prior art, the cooling liquid leakage can be detected by the leakage detection sensor only when the cooling liquid leakage occurs, so that the detection result is more accurate. In the detection mechanism provided in this embodiment, a first gap 24 is formed between the leakage-proof pipe 22 and the coolant pipe 13, and the interior of the housing 21 communicates with the outside through the first gap 24.

In this embodiment, after the housing 21 is provided, leaked cooling liquid may accumulate in the housing 21, and the cooling liquid may corrode the liquid cooling plate 11 and the housing 21 when the cooling liquid contacts the liquid cooling plate 11 and the housing 21 for a long period of time, which affects the service lives of the two.

For this reason, in the present embodiment, when the coolant line 13 is assembled, a first gap 24 is formed between the outer wall of the coolant line 13 and the inner wall of the leakage preventing line 22, and through this first gap 24, the cooling liquid leaked inside the casing 21 can be discharged out of the casing 21 through the first gap 24, avoiding accumulation of the cooling liquid inside the casing 21 for a long period of time.

In the present embodiment, the coolant line 13 and the leakage preventing line 22 are round pipes. In order to form the first gap 24 between the leakage preventing pipe 22 and the coolant pipe 13, it is necessary to satisfy: the coolant line 13 has an outer diameter smaller than an inner diameter of the leakage preventing line 22.

In the detection mechanism provided in this embodiment, a protection cavity 23 is enclosed between the housing 21 and the liquid cooling plate 11, and the protection cavity 23 is communicated with the outside through the first gap 24; the liquid cooling plate 11 is provided with an interface 12 for communicating the outside with the inside of the liquid cooling plate 11, the interface 12 is positioned in the protection cavity 23, and the cooling liquid pipeline 13 is communicated with the interface 12.

In this embodiment, a cooling liquid channel through which cooling liquid circulates is formed in the liquid cooling plate 11, and the cooling liquid channel is an S-shaped channel that is distributed throughout the 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 communicated with the outside and a cooling liquid flow channel, and the cooling liquid pipeline 13 is communicated with the interface 12, and as the main position of the cooling liquid leakage at the liquid cooling plate 11 is the interface 12, the interface 12 is required to be ensured to be positioned in the protection cavity 23 so as to prevent the leaked cooling liquid from flowing onto the heating element.

The shell 21 and the liquid cooling plate 11 jointly enclose into a protection cavity 23, and the protection cavity 23 is arranged in a closed mode, namely, the protection cavity 23 is not communicated with the outside, and cooling liquid can be prevented from leaking to the outside from the protection cavity 23. During assembly, one end of the cooling liquid pipeline 13 penetrates into the leakage-proof pipeline 22 from one end of the leakage-proof pipeline 22 far away from the shell 21, then penetrates out of the leakage-proof pipeline 22 and stretches into the protection cavity 23, a port of the cooling liquid pipeline 13 in the protection cavity 23 is connected with the interface 12, and cooling liquid in an external cooling liquid source can flow into the liquid cooling plate 11 through the cooling liquid pipeline 13.

In the present embodiment, as mentioned above, the liquid cooling plate 11 includes a base plate and a top plate, and in use, the base plate is connected to the heating element, and the interface 12 is provided on the top plate. Correspondingly, the housing 21 is also covered on the top plate, that is to say the top plate and the housing 21 together enclose a protective chamber 23.

In this embodiment, the leak-proof pipe 22 is preferably a hose, which can be adapted to the coolant pipes 13 of different bending forms.

In this embodiment, the housing 21 has a groove-like structure with one end open, and the open end is connected to the top plate when assembled.

According to the detection mechanism provided by the embodiment of the utility model, the shell 21 is connected with the liquid cooling plate 11 to form the protection cavity 23, the interface 12 is protected in the protection cavity 23, and when cooling liquid leaks at the interface 12, the cooling liquid can be temporarily stored in the protection cavity 23, so that the heating element cannot be influenced. Further, since the leakage-proof pipeline 22 sleeved outside the cooling liquid pipeline 13 is further arranged, and the first gap 24 is formed between the leakage-proof pipeline 22 and the cooling liquid pipeline 13, the cooling liquid leaked into the protection cavity 23 can flow out of the protection cavity 23 through the first gap 24, and the cooling liquid can be prevented from influencing the shell 21 and the service life of the heating element, the cooling liquid pipeline 13, the liquid cooling plate 11 and other structures in the shell 21. Damage to the heating element due to leakage of the liquid cooling plate 11 can be effectively avoided. In addition, after the liquid cooling plate 11 is matched with the detection mechanism in the embodiment, the liquid cooling plate 11 is prevented from being stored in the protection cavity 23 even if leakage occurs, and the equipment is not required to be shut down for processing, so that the equipment for using the heating element can realize non-stop operation.

In this embodiment, the liquid cooling plate 11 may be applied to a server scenario such as a CPU (central processing unit) or a video card.

In this embodiment, the connector 12 may be a commercially available elbow with a tower connection at the end of the coolant line 13.

Alternatively, in this embodiment, the material of the housing 21 may 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).

In the present embodiment, when the leak detection sensors are provided in both the leak prevention pipe 22 and the housing 21, the "double insurance" detection can also be realized.

For convenience of description, the leak detection sensor in the casing 21 is a first leak detection sensor, and the leak detection sensor in the leak-proof pipe 22 is a second leak detection sensor.

Specifically, it is assumed that the first liquid leakage detection sensor malfunctions. At this time, the first leakage detection sensor for leakage of the cooling liquid in the protection cavity 23 cannot prompt a technician about leakage of the cooling liquid in the protection cavity 23 in time. However, under the action of the first gap 24 and the second detection, when the cooling liquid flows to the second leakage detection sensor, the second leakage detection sensor detects that the liquid flows in the leakage prevention pipeline 22, and the operator can still be reminded of timely detecting that the cooling liquid leaks from the liquid cooling plate 11, so that the technician can conveniently process the cooling liquid timely.

Simultaneously, through second weeping detection sensor and first weeping detection sensor cooperation, can also remind the technician, whether take place to block up in the leak protection pipeline 22.

As shown in fig. 1 to 5, in the detection mechanism provided by the embodiment of the present utility model, a through hole is formed on a side wall of the housing 21; the cooling liquid pipeline 13 penetrates through the through hole, stretches into the shell 21 and is communicated with the liquid cooling plate 11, and a second gap 25 is formed between the cooling liquid pipeline 13 and the through hole; the leakage-proof pipe 22 is connected to the outer edge of the through hole, and the first gap 24 is communicated with the inside of the housing 21 through the second gap 25.

In the present embodiment, a through hole is provided in a side wall of the housing 21, and the coolant pipe 13 can extend into the housing 21, specifically, into the protection cavity 23 through the through hole. And, the inner diameter of the through hole is larger than the outer diameter of the coolant line 13 so that the second gap 25 can be formed between the coolant line 13 and the through hole. The first gap 24 between the leakage preventing pipe 22 and the coolant pipe 13 communicates with the protection cavity 23 through the second gap 25 between the through hole and the leakage preventing pipe 22.

Optionally, the inner edge of the leakage-proof pipeline 22 is connected with the outer edge of the through hole, so as to avoid the influence of the too small second gap 25 when the leakage-proof pipeline 22 is inserted into the through hole, and the discharge of the cooling liquid through the second gap 25.

In this embodiment, the through hole is communicated with the leakage-proof pipeline 22, so that the structure is simple and the manufacture is convenient.

Alternatively, the coolant line 13 may extend into the housing 21 and the first gap 24 may be in communication with the protection cavity 23 by providing a notch or the like in the housing 21.

Further, in the present embodiment, in order to facilitate connection of the housing 21 to the leakage preventing pipe 22, a connection portion 213 dedicated to connection to the leakage preventing pipe 22 is provided on the housing 21. The connection portions 213 correspond to the through holes, i.e. each through hole is provided with said connection portion 213. The connecting portion 213 is provided with a channel 214, and the channel 214 is communicated with the through hole, that is, the channel 214 is communicated with the inner side and the outer side of the shell 21. The connection 213 is connected to the leak-proof pipe 22. Alternatively, the connection portion 213 and the leakage preventing pipe 22 may be connected by a clamping connection, a plugging connection, a screw connection, or the like.

In the present embodiment, after the leak-proof pipe 22 is assembled with the connecting portion 213, the coolant pipe 13 extends into the interior of the housing 21, specifically, the protection cavity 23 through the passage 214. The second gap 25 has two sections, one section is between the through hole and the coolant pipeline 13, the other section is between the outer wall of the coolant pipeline 13 and the inner wall of the channel 214, and the first gap 24 is communicated with the protection cavity 23 through the second gap 25.

That is, when the detection mechanism is assembled, the leak-proof pipe 22, the passage 214, the through hole, and the inside of the housing 21 are communicated in this order.

When the coolant line 13 is assembled, the end of the coolant line 13 passes through the leakage preventing line 22, the passage 214, and the through hole in this order, and then protrudes into the housing 21.

In this embodiment, the height of the leakage preventing pipe 22 at the end far from the casing 21 is set lower, and the casing 21 is set higher, so that the leaked cooling liquid in the protection cavity 23 is discharged.

For example, a structure such as a through hole is provided on a side wall of the housing 21 opposite to the ground, and this side wall is horizontally provided, and then the leak-proof pipe 22 is vertically provided.

Further, a drainage slope or the like for guiding the cooling liquid to the through hole may be provided in the casing 21, so that the leaked cooling liquid is discharged.

Alternatively, as shown in fig. 3, the connection portion 213 is a cylindrical connector, and the cylindrical connector is inserted into the leakage-proof pipe 22.

In this embodiment, the connection portion 213 is a cylindrical joint corresponding to the leak-proof pipe 22, and the leak-proof pipe 22 is inserted into the cylindrical joint, specifically, the cylindrical joint is inserted into the leak-proof pipe 22.

In this embodiment, the connecting portion 213 is configured as a cylindrical joint, which is compared with square and oval structures, so that an operator can assemble the leak-proof pipeline 22 and the connecting portion 213 conveniently, and the cylindrical joint is convenient to process, is a standard component, and has low cost.

In the detection mechanism provided by the embodiment of the utility model, in order to ensure that the cooling liquid in the protection cavity 23 is not leaked from the connection part of the leakage-proof pipeline 22 and the connection part 213 when the cooling liquid is conveyed outwards, the leakage-proof pipeline 22 and the connection part 213 are arranged in a sealing way.

Alternatively, the leak-proof pipe 22 may be a common hose, and may be sealed by a structure such as a gasket or sealant at the connection.

Optionally, the leakage-proof pipeline 22 may be a heat shrink pipe, and after the connecting portion 213 is inserted into the leakage-proof pipeline 22, the connection strength between the leakage-proof pipeline 22 and the connecting portion 213 is improved by heating, and sealing can be achieved.

By sealing the leakage-proof pipe 22 and the connecting portion 213, the leakage of the cooling liquid leaked from the protection chamber 23 from the leakage-proof pipe 22 to the connecting portion 213 can be prevented, and the cooling liquid leaked from the protection chamber 23 can flow only into the subsequent recovery unit.

As shown in fig. 1 to 5, the housing 21 includes a frame 211 and a cover 212; one end of the frame 211 is connected with the cover plate 212, the other end of the frame 211 is connected with the liquid cooling plate 11, and when the shell 21 is sleeved on the liquid cooling plate 11, the frame 211 and the cover plate 212 jointly enclose the protection cavity 23.

In this embodiment, the housing 21 is divided into two parts, namely a frame 211 and a cover plate 212, and the frame 211 may be a square frame or a round frame, which may be specifically selected according to practical situations.

In this embodiment, one end of the frame 211 is connected to the cover plate 212 to form the groove-shaped structure, the other end of the frame 211 is connected to the top plate of the liquid cooling plate 11, and the top plate of the liquid cooling plate 11, the frame 211 of the housing 21, and the cover plate 212 of the housing 21 together enclose the protection cavity 23.

In the present embodiment, the housing 21 is composed of two parts, namely the frame 211 and the cover plate 212, which has a simple structure, is convenient to manufacture, and has low 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.

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

In this embodiment, the frame 211 and the cover 212 may be integrally formed, i.e. the housing 21 is integrally formed, so that the manufacturing efficiency is high, and meanwhile, the frame 211 and the cover 212 are sealed by integrally forming.

In this embodiment, in order to improve the sealing performance of the protection cavity 23, a sealing structure is specifically provided between the frame 211 and the liquid cooling plate 11, and the sealing structure may be a sealing ring or a sealant provided between the frame 211 and the top plate.

In this embodiment, the frame 211 is connected to the top plate by bolts, and the bolts can fasten the sealing ring, so as to improve the tightness of the protection cavity 23.

In the detection mechanism provided by the embodiment of the present utility model, optionally, the frame 211 and the cover plate 212 are in a split structure, and the frame 211 and the cover plate 212, and the frame 211 and the liquid cooling plate 11 are sealed.

In this embodiment, the frame 211 and the cover plate 212 are in a split structure, and can be connected through structures such as bolts, when the frame 211 or the cover plate 212 is damaged, one of the structures can be replaced independently, so that the maintenance of technicians is facilitated.

In this embodiment, in order to improve the tightness of the protection cavity 23, the sealing arrangement is provided between the frame 211 and the cover plate 212, and before the frame 211 and the top plate. Alternatively, a sealing ring or the like may be disposed between the frame 211 and the cover plate 212 and between the frame 211 and the top plate, or a sealant may be applied.

In this embodiment, the frame 211 and the top plate, and the frame 211 and the cover plate 212 are all connected by bolts.

The detection mechanism provided by the embodiment of the utility model, as shown in fig. 6, further comprises a recovery component; the end of the leakage-proof pipeline 22, which is far away from the shell 21, is communicated with a diversion pipeline 26, and the first gap 24 is communicated with the recovery assembly through the diversion pipeline 26.

In this embodiment, the end of the leakage-proof pipeline 22 far away from the housing 21 is further divided into a branch, namely a diversion pipeline 26, the diversion pipeline 26 is communicated with the leakage-proof pipeline 22, and when the coolant pipeline 13 is installed into the leakage-proof pipeline 22, a first gap 24 is formed between the leakage-proof pipeline 22 and the coolant pipeline 13, and the first gap 24 is communicated with the diversion pipeline 26.

In this embodiment, the recovery unit may be a recovery tank or a waste liquid tank, etc., which is used to recover leaked cooling liquid. The leakage-proof pipeline 22 is communicated with the recovery assembly through the diversion pipeline 26, and the cooling liquid leaked into the protection cavity 23 and/or the first gap 24 flows into the recovery assembly through the diversion pipeline 26, so that the leaked cooling liquid is prevented from damaging external devices or the environment, and loss is reduced.

In the detection mechanism provided by the embodiment of the utility model, in general, the liquid cooling plate 11 is provided with two interfaces 12, correspondingly, the detection mechanism comprises two leakage-proof pipelines 22, and two connecting parts 213 are arranged on the shell 21.

In the present embodiment, a plurality of liquid cooling plates 11 may be connected in series when the liquid cooling plates 11 are in use. Taking two liquid cooling plates 11 as an example, the two liquid cooling plates 11 are provided with three cooling liquid pipelines 13, one of the three cooling liquid pipelines is used as a liquid inlet pipeline and is connected with an interface 12 on one of the liquid cooling plates 11, the other liquid pipeline is used as a liquid outlet pipeline and is connected with an interface 12 on the other liquid cooling plate 11, and two ends of the remaining cooling liquid pipeline 13 are connected with the remaining interfaces 12 on the two liquid cooling plates 11.

Correspondingly, the detection mechanism comprises two shells 21 and three leakage-proof pipelines 22, the three leakage-proof pipelines 22 correspond to the three cooling liquid pipelines 13, the two shells 21 are respectively covered on the two liquid cooling plates 11, and the three leakage-proof pipelines 22 are respectively sleeved outside the corresponding cooling liquid pipelines 13.

Further, since the housing 21 is at the lowest position as a whole when the liquid cooling device of the server is mounted, liquid is accumulated in the housing 21 when liquid leaks, and thus a liquid leakage detection sensor is disposed inside the housing 21.
