Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

In order to better understand the aspects of the present application, a further detailed description of the present application will be provided below with reference to the accompanying drawings and detailed description.

The high power consumption module of the whole server is divided into a plurality of parts, including a CPU (Central Processing Unit), a computing unit translated into a CPU) +an internal memory, a memory card+a memory module of a hard disk and an expansion card module. The CPU is used as the operation and control core of the computer system and is the final execution unit for information processing and program running. In the design of the server, as the performance requirement of the CPU is improved, the power consumption of the CPU is increased suddenly, and when the power consumption of the CPU exceeds a certain value (for example, 350W), the conventional air cooling is insufficient to meet the heat dissipation requirement, and the liquid cooling heat dissipation design is required for the CPU with the power consumption exceeding a certain value (for example, 350W).

At present, there is no liquid leakage detection device designed specifically for liquid leakage detection of a liquid cooling server, and the liquid leakage detection means for the liquid cooling server is single. Because of the improvement of CPU power consumption, the number of positions needing liquid cooling heat dissipation is increased, the number of liquid cooling heat dissipation pipelines is correspondingly increased, and the risk of leakage of cooling liquid is synchronously increased; at this time, the conventional leakage detection means cannot meet the requirement of leakage detection of the liquid cooling server, and particularly, judgment of the leakage position is a pain point of current leakage detection.

To above-mentioned technical problem, this application provides a liquid cooling server weeping detection device, aims at making the improvement to traditional weeping solution to improve the detection effect to the weeping, help managers to find the weeping position fast and accurately and make the processing, so as to promote the security and the stability of liquid cooling server operation.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a liquid leakage detection device and a liquid cooling pipeline of a liquid cooling server according to an embodiment of the present application.

As shown in fig. 1, the reference number structure in fig. 1 mainly includes a liquid-cooling server leakage detection device 100 and a liquid-cooling pipeline 200; in some cases, the liquid-cooling server leakage detection device 100 includes the device main body 11 and the leakage detection cable 21, and as an alternative, the liquid-cooling server leakage detection device 100 may further include other structures on the basis of having included the device main body 11 and the leakage detection cable 21, which shall fall within the scope of the present embodiment.

In a specific embodiment, the liquid-cooled server leakage detection device 100 mainly includes a device main body 11 and a leakage detection cable 21.

The device main body 11 mainly serves as an external structure of the liquid-cooling server leakage detection device 100, and serves as a support for an internal structure of the liquid-cooling server leakage detection device 100 and as a mounting on the liquid-cooling line 200 of the liquid-cooling server. The internal structure of the liquid-cooling server leakage detection device 100 is referred to herein as a leakage indicator 12, and the leakage indicator 12 is provided inside the device main body 11, and when the device main body 11 is mounted on the liquid-cooling pipeline 200 of the liquid-cooling server, the leakage indicator 12 is mounted on the liquid-cooling pipeline 200 of the liquid-cooling server together with the device main body 11 under the action of the load. The leakage indicator 12 can absorb water and change color, because the liquid can cause the leakage indicator 12 to change color, and the color change position is the leakage position, which is equivalent to the positioning of the leakage through the leakage indicator 12.

The leakage detection cable 21 is mounted on the device main body 11, and the leakage detection cable 21 is connected with the server controller 300, so that the signal of the leakage detection cable 21 is changed due to the generation of liquid, which is equivalent to the judgment of the leakage through the leakage detection cable 21, and the obtained signal is sent to the server controller 300, thereby realizing the alarm when the leakage of the leakage detection cable 21 occurs.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a liquid leakage space according to an embodiment of the present disclosure.

As shown in fig. 2, the reference numerals in fig. 2 mainly include a liquid leakage space 101, a liquid-cooling server liquid leakage detection device 100, and a liquid-cooling pipeline 200. As can be seen from fig. 2, a liquid leakage space 101 is formed between the inside of the device body 11 and the outside of the liquid cooling pipeline 200, at this time, the liquid leakage space 101 is enclosed by the device body 11 at the periphery, the liquid leakage space 101 forms a wrapping cover for the liquid cooling pipeline 200, and the coverage of the liquid leakage space 101 to the liquid cooling pipeline 200 is the liquid leakage detection range of the liquid cooling server liquid leakage detection device 100 to the liquid cooling pipeline 200, that is, once the liquid cooling pipeline 200 leaks, the leaked liquid directly enters the liquid leakage space 101, at this time, the liquid leakage of the liquid cooling pipeline 200 is equal to the liquid leakage in the liquid leakage space 101. Referring to fig. 1 again, it can be seen that, since the liquid leakage indicator 12 is disposed in the liquid leakage space 101, when liquid leakage occurs in the liquid cooling pipeline 200, that is, when liquid occurs in the liquid leakage space 101, the liquid leakage indicator 12 will change in color, so as to realize color-changing positioning of the liquid leakage position in the liquid leakage detection range.

In some cases, the leakage detection cable 21 is mounted on the device main body 11, and after the leakage detection cable 21 passes through the device main body 11 and enters the interior, the leakage detection cable 21 passes through the leakage space 101, and at this time, the detection range of the leakage detection cable 21 covers the leakage space 101, so that the leakage detection cable 21 can at least detect the leakage in the leakage space 101, and send the detected signal to the server controller 300, so that it is realized that the leakage detection cable 21 alarms when the leakage occurs in the leakage space 101.

In the implementation of the liquid-cooling server leakage detection device 100, the device body 11 and the leakage detection cable 21 may be assembled into a single unit, so that the single unit is purposefully installed on the liquid-cooling pipeline 200 of the liquid-cooling server, where the installation position of the single unit is a leakage detection position where it is necessary to detect whether or not leakage exists; in addition, instead of assembling the device main body 11 and the leakage detection cable 21, a leakage detection position where whether or not leakage is detected is purposefully selected on the liquid cooling line 200 of the liquid cooling server may be set as an installation position, and then the device main body 11 and the leakage detection cable 21 may be assembled at the installation position.

In the use process of the liquid cooling server leakage detection device 100, the installation of the liquid cooling server leakage detection device 100 on the liquid cooling pipeline 200 of the liquid cooling server is finished in advance, the installation position of the liquid cooling server leakage detection device 100 is a leakage detection position for detecting whether leakage exists, at this time, the device main body 11 of the liquid cooling server leakage detection device 100 is installed with the liquid cooling pipeline 200, and the positions of the device main body 11 and the liquid cooling pipeline 200 are relatively fixed, so that the position of a leakage space 101 formed between the inside of the device main body 11 and the outside of the liquid cooling pipeline 200 is also fixed, and once the liquid cooling pipeline 200 leaks at the leakage detection position, the cooling liquid inevitably enters the leakage space 101 between the liquid cooling pipeline 200 and the device main body 11; in this way, if the liquid cooling pipeline 200 leaks, the detection range of the leak detection cable 21 covers the leak space 101, so that the leak detection cable 21 detects a leak condition, and the leak detection cable 21 is connected to the server controller 300, which corresponds to sending a leak signal of the leak detection cable 21 detecting the leak condition to the server controller 300, thereby realizing an alarm function when the leak space 101 leaks; meanwhile, if the liquid cooling pipeline 200 leaks, the liquid leakage indicator 12 is disposed in the liquid leakage space 101, and the liquid leakage indicator 12 changes color when the liquid leakage occurs in the liquid leakage space 101, so that the liquid leakage indicator 12 indicates the position where the liquid leakage occurs in a color-changing manner, thereby realizing the color-changing positioning function when the liquid leakage occurs in the liquid leakage space 101.

The above structure and process description for the technical scheme can be combined to obtain the following beneficial effects: the liquid cooling server leakage detection device 100 can detect the leakage condition of the liquid cooling pipeline 200, when leakage occurs, the leakage detection cable 21 reports the server controller 300 to alarm, and after receiving the alarm, a manager can quickly find the leakage position according to the color change position of the leakage indicator 12 and process the leakage position, thereby improving the safety and stability of the operation of the liquid cooling server.

It should be noted that the core of this embodiment is the alarm function and the color-changing positioning function. In some cases, taking the server controller 300 as the server BMC (Baseboard Management Controller, translated in chinese as a baseboard management controller), the liquid-cooled server leak detection apparatus 100 and the liquid-cooled pipeline 200 as examples, for the alarm function: the leakage detection cable 21 is used for alarming on the BMC to prompt the system to leak; for the color-changing positioning function: when the BMC sends out a leakage alarm, the case is opened, and the leakage indicator 12 is in color change after contacting with the leaked liquid, so that the leakage position can be immediately positioned.

It should be noted that, for the above color-changing positioning function, different technical effects may be generated according to different description objects.

Firstly, a single liquid-cooling server leakage detection device 100 is taken as a description object, because the liquid-cooling server leakage detection device 100 is an area covering a plurality of positions where the liquid-cooling pipeline 200 may leak, when the liquid-cooling pipeline 200 leaks, on one hand, the leakage detection cable 21 gives an alarm, on the other hand, the leakage indicator 12 changes color, and a specific color-changing position of the leakage indicator 12 indicates a specific position in the area where the liquid-cooling pipeline 200 actually leaks, thereby realizing the color-changing positioning function of the leakage indicator 12 in the single liquid-cooling server leakage detection device 100.

In addition, the liquid-cooling server leakage detection device 100 of the group is taken as a description object, at this time, the liquid-cooling server leakage detection device 100 of the group is equivalent to performing leakage detection on a plurality of leakage detection ranges, that is, a plurality of areas on the liquid-cooling pipeline 200, when the liquid-cooling pipeline 200 has leakage, the plurality of areas on the liquid-cooling pipeline 200 have the possibility of having leakage, and the specific color-changing position of the liquid-leakage indicator 12 indicates the specific area on the liquid-cooling pipeline 200 where the liquid-leakage actually occurs, so that the color-changing positioning function of the liquid-leakage indicator 12 in the liquid-cooling server leakage detection device 100 of the group is realized.

Based on the color-changing positioning function of the liquid leakage indicator 12 in the liquid-cooling server liquid leakage detection device 100 of the group, the color-changing positioning function of the liquid leakage indicator 12 in the single liquid-cooling server liquid leakage detection device 100 can be further combined, so that on the basis that the liquid leakage indicator 12 indicates a specific area on the liquid-cooling pipeline 200 in which the liquid leakage occurs actually, the specific position of the liquid-cooling pipeline 200 in the specific area is indicated again in the specific area.

Referring to fig. 3, fig. 3 is a schematic structural diagram of a loading space according to an embodiment of the present application.

As shown in fig. 3, the reference numeral structure referred to in fig. 3 mainly includes a loading space 102, a first set of layers 111, and a second set of layers 112.

In a specific embodiment, the device body 11 includes a first set of layers 111 and a second set of layers 112, and as can be seen in fig. 3, the first set of layers 111 is located outside the second set of layers 112 and encloses the second set of layers 112, and a loading space 102 is formed between the first set of layers 111 and the second set of layers 112, and as can be seen in connection with fig. 2, the loading space 102 is located in the liquid leakage space 101, and as can be seen in connection with fig. 1, the liquid leakage indicator 12 is mounted in the loading space 102.

In this embodiment, the liquid leakage space 101 and the loading space 102 belong to the internal space of the liquid cooling server liquid leakage detection device 100, and the loading space 102 serves as an interlayer further dividing the liquid leakage space 101, and the interlayer serves to provide a bearing function for the internal structure of the liquid cooling server liquid leakage detection device 100.

In this way, the leakage indicator 12 can be properly installed in the loading space 102, and thus the processing and assembling requirements of the leakage indicator 12 can be reduced. In some cases, if the loading space 102 formed by the first set of layers 111 and the second set of layers 112 is compared with the bag body, the leakage indicator 12 may be particles filled in the bag body, and the structural form of the particles can be well adapted to the spatial form of the loading space 102, so that the loading space 102 is beneficial to be designed into a flat structural form, thereby effectively reducing the volume of the structure and improving the light weight and convenience of the device while ensuring that the color-changing positioning function is not affected.

Referring to fig. 4, fig. 4 is a schematic structural diagram of a liquid leakage detection device of a liquid cooling server according to an embodiment of the present application.

As shown in fig. 4, the reference numeral structure referred to in fig. 4 mainly includes a first set of layers 111, a waterproof and breathable portion 1111, an air vent 11111, a second set of layers 112, a water-absorbing and breathable portion 1121, and a capillary channel 11211. Comparing fig. 4 with fig. 1, it can be seen that fig. 4 conceals the liquid cooling line 200 of fig. 1.

In some embodiments, the first sleeve layer 111 includes at least one layer of waterproof and breathable sections 1111.

In this embodiment, the waterproof and breathable portion 1111 is equivalent to an outer skin of an interlayer on which the leakage indicator 12 is mounted, and the waterproof and breathable portion 1111 is transparent, so that a manager can observe the color of the leakage indicator 12 inside through the waterproof and breathable portion 1111, and the accuracy of the observation result is improved while the light incidence is improved in a transparent manner, so that the influence of other colors on the observation of the color of the leakage indicator 12 is avoided.

The waterproof ventilation part 1111 is provided with ventilation holes 11111, the ventilation holes 11111 are used for preventing liquid from passing through when gas passes through, and the ventilation holes 11111 prevent liquid from passing through the first sleeve layer 111 in the direction from the second sleeve layer 112 to the first sleeve layer 111, which is equivalent to preventing liquid in an interlayer from being in the interlayer and not leaking to the outside of the liquid-cooling server liquid leakage detection device 100.

In some cases, the waterproof and breathable portion 1111 may be a waterproof and breathable film, and the waterproof and breathable film has the ventilation holes 11111, so that the ventilation and waterproof functions of the waterproof and breathable film are realized through the ventilation holes 11111, and the liquid leakage of the liquid cooling pipeline 200 can be prevented from dropping to other places through the liquid cooling server liquid leakage detection device 100. The waterproof breathable film works as follows.

The interval between gas molecules is larger, and the gas molecules can pass through the ventilation holes 11111 of the waterproof and breathable film in the diffusion movement process; the distance between the liquid molecules is smaller than the distance between the ventilation holes 11111, and the liquid molecules cannot penetrate through the waterproof breathable film under the action of surface tension, so that the waterproof effect is achieved.

With continued reference to fig. 4, in some embodiments, the second sleeve layer 112 includes at least one layer of absorbent breathable sections 1121.

In this embodiment, the water-absorbing and air-permeable portion 1121 is equivalent to an inner surface of an interlayer for loading the leakage indicator 12, the waterproof and air-permeable portion 1111 is transparent to facilitate the observation of the color of the leakage indicator 12 inside by the manager, and the water-absorbing and air-permeable portion 1121 is also required to be specially designed to maintain the color difference between the color of the water-absorbing and air-permeable portion 1121 and the color of the leakage indicator 12 before, after and during the change, so as to avoid the influence of other color entrainment on the observation of the color of the leakage indicator 12 and improve the accuracy of the observation result.

The water-absorbing and air-permeable portion 1121 is provided with capillary channels 11211, the capillary channels 11211 being configured to draw liquid through, and the capillary channels 11211 being configured to draw liquid through the second jacket 112 in a direction from the second jacket 112 to the first jacket 111, which is equivalent to drawing liquid leaking from the liquid-cooled piping 200 into the interlayer.

In some cases, the water-absorbing and air-permeable portion 1121 may be gauze, where the gauze has capillary channels 11211, and the reversible gravity water-absorbing function of the gauze is implemented through the capillary channels 11211, so as to promote the liquid leakage of the liquid-cooling pipeline 200 into the interlayer of the liquid-cooling server liquid-leakage detection device 100. The gauze works as follows.

Fine capillary channels 11211 are formed among the fibers of the gauze, the capillary channels 11211 act like capillaries, and the surface tension of the liquid is utilized to raise the infiltration liquid in the capillary channels 11211, namely, the capillary water absorption function is achieved.

With continued reference to fig. 1, in some embodiments, the device body 11 further includes a mounting seal 113, the mounting seal 113 connecting the first set of layers 111 and the second set of layers 112 and sealing the loading space 102, the mounting seal 113 further being configured to connect with the liquid cooling conduit 200.

In this embodiment, the liquid-cooling server leakage detection device 100 not only includes the leakage indicator 12 and the leakage detection cable 21, but also includes the leakage absorber 13, and at this time, the liquid-cooling server leakage detection device 100 not only has an alarm function and a color-changing positioning function, but also has a water absorption function, so as to detect the leakage condition of the liquid-cooling pipeline 200 and absorb the leakage, avoid the liquid flowing when the leakage occurs, and perform alarm waiting processing.

Alternatively, the leakage indicator 12 and the leakage absorber 13 are similar in structural form, and both structures are filled together in the interlayer, i.e., the loading space 102.

The leakage absorber 13 works as follows.

The leak absorber 13 is optionally a molecular sieve desiccant, which is a crystalline aluminosilicate having a uniform pore size and extremely high specific surface area, and thus has many excellent characteristics. First, molecular sieves are capable of selective adsorption according to the size and shape of the molecules, adsorbing only molecules smaller than their pore size. Secondly, for small polar molecules and unsaturated molecules, the molecular sieve has selective adsorption capacity, and the higher the polarity and the higher the unsaturation degree, the stronger the selective adsorption performance.

The transparent waterproof ventilated membrane in top layer parcel gauze layer can prevent that the water that liquid cooling pipeline 200 spilled from passing device main part 11 and drip to PCB (Printed Circuit Board, chinese translates into printed circuit board), and when the complete machine was operated under high humidity environment simultaneously, the steam of computer lab can't permeate the transparent waterproof ventilated membrane in top layer, has guaranteed that weeping absorber 13 is effective for a long time. The middle mixed layer is formed between the gauze layer and the surface layer transparent waterproof breathable film, the middle mixed layer is provided with a liquid leakage indicator 12 and a molecular sieve drying agent, the middle mixed layer is also penetrated with a liquid leakage detection cable 21, and a part of the molecular sieve drying agent is sleeved on the liquid leakage detection cable 21.

When the device is specifically used, after water leakage occurs in the liquid cooling pipeline 200, water can quickly drop to the gauze layer, after the gauze layer absorbs water, the water flows to the desiccant and the color-changing orange glue, after the desiccant is wetted, the anode and the cathode of the liquid leakage detection cable in the middle of the desiccant are short-circuited under the action of a water film, and the server gives an alarm.
