Description

Technical Field

[0001] This invention relates to the field of leakage detection technology, and in particular to a leakage detection module. Background Technology

[0002] In liquid cooling systems, liquid cooling devices deliver coolant through closed pipes to efficiently remove heat generated during equipment operation. Compared to traditional air cooling, liquid cooling offers advantages such as high heat dissipation efficiency, low noise, and low energy consumption, making it the mainstream technology for cooling high-density, high-power electronic equipment. The pipe connections between pipes and between pipes and liquid cooling devices in a liquid cooling system are formed by joints. These joints, as the splicing nodes of the liquid cooling system, are susceptible to leaks due to factors such as assembly precision, pipe vibration, medium pressure fluctuations, and material aging. Leaks at these pipe connections not only significantly reduce the cooling efficiency of the liquid cooling system, failing to meet the equipment's cooling requirements, but can also cause short circuits in surrounding electrical equipment, corrosion of metal components, and insulation failure. In severe cases, they can even lead to equipment shutdowns, fires, and other major safety accidents. Therefore, real-time and reliable leak detection at liquid cooling pipe connections is a core aspect of liquid cooling system safety protection.

[0003] There are two main existing leak detection solutions: one is to install a leak sensing circuit board at the bottom of the pipe connection. This solution requires specific design based on the planar structure of different liquid cooling devices, resulting in poor adaptability. When the pipe size or device structure changes, the sensing circuit board cannot be reused, increasing operating costs. The other solution involves winding a large amount of liquid cooling detection wire around the pipe. To ensure detection stability, multiple winding operations are required during construction, which is cumbersome, inefficient, and difficult to precisely control the winding density, easily leading to blind spots or resource waste. Neither of these solutions can simultaneously achieve adaptability and ease of construction, making it difficult to meet the leak detection needs of liquid cooling pipe connections of different specifications.

[0004] Furthermore, both existing solutions rely on the resistance change of conductive liquids for detection. The detection electrodes cannot distinguish between condensation on pipes caused by high humidity, moisture in the air, and actual leaking cooling liquid. In high-humidity environments such as the rainy season in southern China, data center cold aisles, underground server rooms, and outdoor server racks, moisture in the air or condensation caused by temperature differences between the inside and outside of the pipes can directly contact the detection electrodes, causing changes in resistance and triggering false alarms. Frequent false alarms not only increase the workload for maintenance personnel but also lead to complacency regarding alarm signals, resulting in a failure to respond promptly to actual leaks and posing a serious safety hazard.

[0005] In summary, existing leak detection solutions cannot simultaneously achieve universality, ease of construction, and reliability. They are insufficient to meet the leak detection needs of liquid-cooled pipe connections of different sizes, and they also cannot achieve stable and reliable leak detection in high-humidity environments. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies, this invention proposes a leak detection module that simultaneously solves the core problems of poor adaptability, cumbersome construction, and false alarms in high humidity environments of existing leak detection solutions. It can be universally adapted to liquid-cooled pipes of different outer diameters without the need for customized design based on pipe size. At the same time, it greatly simplifies the installation and construction steps, improves installation efficiency, and can effectively prevent false alarms caused by environmental moisture and pipe condensation. It can also maintain reliable leak detection performance in high humidity environments, taking into account versatility, convenience, and reliability, and meeting the actual use needs of liquid cooling systems.

[0007] To achieve this objective, the present invention adopts the following technical solution: This invention provides a leakage detection module, comprising a wrapping part and a detection part. The wrapping part forms a surrounding structure around the connection of a liquid-cooled pipe, and the size of the wrapping structure is adaptively adjustable to accommodate liquid-cooled pipes of different outer diameters. The detection part is fixed inside the surrounding structure and is used to detect leakage at the connection of the liquid-cooled pipe. A false alarm prevention part is provided on the side of the detection part facing the connection of the liquid-cooled pipe. This part absorbs ambient moisture and condensation on the pipe surface to prevent direct contact between non-leaking moisture and the detection part, while simultaneously providing a conductive path for leaking liquid from the pipe connection to contact the detection part. The surrounding structure in the above technical solution includes, but is not limited to, circular or square structures.

[0008] The present invention provides a leakage detection module, wherein a connecting end is provided at one circumferential end of the package and an adjustable area is provided at the other circumferential end. The connecting end and the adjustable area are detachably coupled to form a closed ring structure. The inner diameter of the ring structure is adjusted by adjusting the relative fixed position of the connecting end and the adjustable area.

[0009] The present invention provides a leakage detection module in which the wrapping part is an elastic rolled structure in its natural state. When an external force is applied, the elastic rolled structure can overcome the elastic force and form an unfolded state. When the force is withdrawn, the wrapping part automatically changes from the unfolded state to the rolled state and forms a closed wrapping structure.

[0010] This invention provides a leakage detection module. A first connecting end and a second connecting end are respectively provided at both circumferential ends of the wrapping portion. The first connecting end and the second connecting end are detachably connected to form a closed surrounding structure. An elastic extension portion is also provided on the wrapping portion, which adjusts the inner diameter of the surrounding structure through its own elastic deformation. The elastic extension portion in the above technical solution can be an integral elastic structure of the wrapping portion, or it can be a partial elastic structure to achieve internal size adjustment of the surrounding structure of the wrapping portion.

[0011] The present invention provides a leakage detection module, wherein the false alarm prevention part is a moisture-absorbing substrate, the moisture-absorbing substrate includes an integrally formed moisture-absorbing part and a flow-guiding part; the moisture-absorbing part is used to absorb and lock in ambient water vapor and condensation on the pipe surface, and the flow-guiding part penetrates the moisture-absorbing substrate along the thickness direction to guide the leakage at the pipe connection to the detection part.

[0012] The present invention provides a leakage detection module in which the detection part and the wrapping part are fixedly connected by a weaving method; or the inner side of the wrapping part is provided with a slot structure, and the detection part is fixedly engaged with the wrapping part by the slot structure.

[0013] The present invention provides a leakage detection module, wherein the inner side plate of the slot structure has a plurality of liquid passage holes, which are connected along the thickness direction of the inner side plate to allow leakage at the pipe connection to permeate to the detection part.

[0014] The present invention provides a leakage detection module in which the wrapping part is provided with baffles extending in a closed loop along the circumference at both ends of the axial structure. The two baffles and the inner sidewall of the wrapping part form an annular anti-leakage groove, which is used to catch leakage at the pipe connection.

[0015] The present invention provides a leakage detection module, which further includes a signal processing unit electrically connected to the detection unit. The signal processing unit has a preset condensation threshold and a leakage threshold. The signal processing unit is used to distinguish between pipeline condensation and actual leakage based on the amplitude and rate of change of the detection signal, and outputs a corresponding alarm signal.

[0016] The present invention provides a leakage detection module, wherein the detection part is a flexible printed circuit board (FPC) or a liquid-cooled detection line; the material for the wrapping part is any one of thermoplastic polyurethane elastomer (TPU), polyester, or polyamide.

[0017] Beneficial effects of this medicine: This invention, through its adaptively adjustable inner diameter surrounding structure, eliminates the need for customized design of the wrapping part based on the outer diameter of the liquid cooling pipe and the device structure. It can universally adapt to liquid cooling pipe connections of different specifications, fundamentally solving the problem of poor adaptability in existing technologies. This significantly reduces the production and inventory costs and operating costs of the product, and can cope with installation scenarios with varying pipe specifications on site.

[0018] This invention directly forms a surrounding structure for the encasing pipe through the wrapping part, eliminating the need for multiple wrapping and fixing of the detection line, as well as the need for customized mounting brackets. The module can be installed and fixed with simple operation, which greatly simplifies the construction steps, reduces construction difficulty and labor costs, and significantly improves installation efficiency, thus meeting the batch installation needs of large-scale liquid cooling systems.

[0019] This invention, by setting up an anti-false alarm unit between the detection unit and the pipeline, can actively absorb ambient moisture and pipeline condensation, thus avoiding false alarms caused by non-leakage factors at the source. It can also ensure that real leaks quickly contact the detection unit, preventing missed detections, thus greatly improving the reliability of leak detection and enabling the module to operate stably for a long time under complex working conditions with high humidity.

Detailed Implementation

[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1 like Figure 1-3 As shown, this embodiment provides a leakage detection module, including a wrapping part 1 and a detection part 2. The wrapping part 1 is used to form a surrounding structure for wrapping the connection of the liquid cooling pipe. The size of the surrounding structure can be adaptively adjusted to adapt to liquid cooling pipes with different outer diameters. The detection part 2 is fixed to the inner side of the surrounding structure and is used to detect leakage at the connection of the liquid cooling pipe. A false alarm prevention part 3 is provided on the side of the detection part 2 facing the connection of the liquid cooling pipe. The false alarm prevention part 3 is used to absorb ambient water vapor and condensation on the pipe surface to prevent non-leakage water from directly contacting the detection part 2, while providing a conductive path for leakage seeping from the pipe connection to contact the detection part 2.

[0025] In this embodiment, the detection unit 2 is powered on and connected to a connecting wire 4, which transmits the leakage detection signal to an external monitoring system via a wired connection. In other alternative embodiments, a wireless communication module can also be provided on the detection unit 2 to transmit the detection signal wirelessly via methods including but not limited to Bluetooth, LoRa, 4G, etc.

[0026] The functions, relationships, and working principles of each core component in this embodiment will now be explained in detail: The wrapping part 1 is the main supporting body of this module. Its core function is to form a surrounding structure that wraps around the connection of the liquid-cooled pipe, providing a stable installation reference for the detection part 2, and achieving universal adaptation to pipes with different outer diameters. In this embodiment, the wrapping part 1 is made of flexible insulating material. The wrapping part 1 is provided with a first connecting end 11 and a second connecting end 12. The first connecting end 11 and the second connecting end 12 are detachably connected so that the wrapping part is constructed as a surrounding structure that wraps around the connection of the liquid-cooled pipe. The wrapping part 1 is also provided with an elastic extension part. The size of the surrounding structure is adjusted by the elastic deformation of the elastic extension part, which can be adjusted and adapted according to the outer diameter of the pipe, so that the wrapping part 1 can fit the outer wall of the pipe and ensure the relative position stability of the detection part 2 and the connection of the pipe.

[0027] Specifically, the first connecting end 112 and the second connecting end 113 are connected by a snap-fit ​​connection. The first connecting end 112 is provided with a snap-fit ​​female seat, and the second connecting end 113 is provided with a matching snap-fit ​​male head. The two ends of the wrapping part 1 are fixed by the snap-fit ​​between the male head and the female seat, forming a closed loop structure. This snap-fit ​​connection method is a tool-free connection structure. Construction personnel only need to manually operate to quickly wrap the connection between the wrapping part 1 and the liquid cooling pipe, without carrying additional tools, simplifying the construction steps and meeting the needs of rapid on-site construction. At the same time, the snap-fit ​​connection has a mechanical limiting function, and a stable connection relationship can be formed after snapping, ensuring that the loop structure will not loosen due to pipe vibration, equipment operation, or other factors.

[0028] Here, the surrounding structure will be explained in detail again: The surrounding structure refers to the closed circumferential enclosure formed by the wrapping part 1 around the connection of the liquid-cooled pipe. This enclosure can constrain the detection part 2 to the outer periphery of the pipe connection, achieving coverage of the pipe connection and avoiding detection blind spots. This includes, but is not limited to, circular and square structures.

[0029] In this embodiment, the dimensions of the surrounding structure are adaptively adjustable. The core principle lies in the elastic extensibility of the wrapping part 1, which allows for deformation adjustment. It can adjust its encircling diameter according to the actual outer diameter of the pipe to be installed, eliminating the need for pre-customized processing based on pipe dimensions. This enables module products of the same specification to adapt to liquid-cooled pipes of different outer diameters, fundamentally solving the problem of poor compatibility of customized sensing circuit boards in existing technologies. Compared to existing technologies that require customization of different specifications based on pipe dimensions, the modules in this embodiment significantly reduce the variety of specifications required for production and inventory, lowering production mold and inventory costs. Furthermore, during on-site construction, there is no need to select products of corresponding specifications based on pipe dimensions, further improving construction efficiency.

[0030] Detection unit 2 is the core functional component of this module, used to detect leaks at the connection of liquid-cooled pipes. Its detection principle is based on the resistance change characteristics of conductive liquids: Detection unit 2 is equipped with mutually insulated positive and negative detection electrodes. When there is no leak at the pipe connection, the positive and negative electrodes are in an insulated state, and detection unit 2 outputs a high-level signal; when a leak occurs at the pipe connection, the conductive coolant comes into contact with the positive and negative electrodes, forming a conductive circuit between the two electrodes, and the resistance changes. Detection unit 2 outputs a corresponding low-level detection signal, and the external monitoring system triggers a leak alarm based on the change in the detection signal.

[0031] In this embodiment, the detection unit 2 is fixed inside the surrounding structure. This positioning has the following key advantages: First, the detection unit 2 can directly face the outer wall of the liquid cooling pipe connection, and the leaking liquid at the pipe connection can contact the detection unit 2 immediately, greatly shortening the detection response time; Second, the detection unit 2 matches the surrounding structure of the wrapping part 1 to form a circumferential covering structure, so that no matter where the leak occurs at the pipe connection, it can quickly contact the detection unit 2, avoiding the detection blind spot caused by uneven winding of the detection line in the prior art; Third, the detection unit 2 is clamped and fixed by the wrapping part 1 and the outer wall of the pipe, and its position is stable. It will not be displaced due to pipe vibration or external force, ensuring the accuracy of the detection position during long-term use.

[0032] False Alarm Prevention Department 3 The false alarm prevention unit 3 is located on the side of the detection unit 2 facing the connection of the liquid-cooled pipe, that is, in the area between the detection unit 2 and the outer wall of the pipe. Its core function is to achieve the dual functions of "non-leakage moisture blocking" and "leakage conduction". It solves the core defect of the prior art that is prone to false alarms in high humidity environments. It can actively adsorb and lock the gaseous water vapor diffused in the environment and the condensation formed on the pipe surface due to the temperature difference between the inside and outside, so as to prevent the moisture of such non-leakage factors from directly contacting the detection electrode of the detection unit 2 and triggering false alarms. At the same time, it can provide a conduction path for the liquid coolant that is actually leaking in the pipe, so as to ensure that the leaking liquid can quickly and stably contact the detection electrode of the detection unit 2 to realize the leakage detection function and prevent missed detection.

[0033] In this embodiment, the working principle of the false alarm prevention unit 3 is as follows: gaseous water vapor in the environment and trace amounts of condensation formed on the surface of the pipe will be actively adsorbed and locked inside the structure by the false alarm prevention unit 3, and will not form free-flowing liquid water. Therefore, they cannot contact the detection electrode of the detection unit 2, thus avoiding false alarms caused by non-leakage factors from the source. When a real leak occurs at the pipe connection, a large amount of liquid coolant will break through the water-locking threshold of the false alarm prevention unit 3 and contact the detection electrode of the detection unit 2 through the conduction path inside the structure, triggering a leak alarm and ensuring the normal realization of the leak detection function.

[0034] Specifically, the false alarm prevention unit 3 is a moisture-absorbing substrate 31, which includes an integrally formed moisture-absorbing part 32 and a flow-guiding part 33. The moisture-absorbing part 32 is used to absorb and lock in ambient moisture and condensation on the pipe surface, and the flow-guiding part 33 penetrates the moisture-absorbing substrate 31 along the thickness direction to guide the leakage at the pipe connection to the detection unit 2. In this embodiment, the moisture-absorbing substrate 31 is made of cotton or absorbent resin. Both materials are standardized materials that are maturely used in the industrial field, with stable and controllable performance, no corrosiveness, and will not damage the pipe and the detection unit 2. At the same time, they have excellent structural compatibility and can be perfectly adapted to the structural design of the module. Among them, cotton refers to a natural cellulose material with a continuous hydrophilic fiber structure, which has good hydrophilicity and flexibility. It can be freely deformed with the bending of the wrapping part 1 and maintain a good fit with the outer wall of the pipe. At the same time, it is inexpensive and suitable for use in normal humidity scenarios. Water-absorbing resin refers to a synthetic polymer water-absorbing material with a three-dimensional cross-linked network structure. It has extremely strong water absorption and water-locking capacity, and the water absorption capacity can reach hundreds of times its own weight. The adsorption effect is long-lasting, and it is not easy to leak after absorbing moisture. It can maintain a dry state for a long time and is suitable for high humidity and long-term operation scenarios without frequent replacement of the adsorption layer.

[0035] In this embodiment, the thickness of the moisture-absorbing substrate 31 can be selected as 0.3mm-3mm. This parameter range is the optimal range verified by a large number of experiments, which can balance the three core performance characteristics of moisture absorption capacity, structural adaptability, and detection response speed. The thickness mentioned here refers to the dimension of the moisture-absorbing substrate 31 in the radial direction of the pipe, that is, the thickness of the substrate from the outer wall of the pipe to the detection part 2. The forming thickness of the substrate can be precisely controlled by hot pressing process, and the tolerance can be controlled within ±0.1mm to ensure the performance consistency of mass production.

[0036] For this numerical range, this embodiment provides three specific implementation methods, corresponding to the endpoints and the intermediate value of the range, respectively: Implementation method with a thickness of 0.3mm: In this embodiment, the thickness of the moisture-absorbing substrate 31 is 0.3mm. This thickness ensures that the moisture-absorbing substrate 31 has a basic moisture absorption capacity, meets the long-term use requirements under normal humidity scenarios (relative humidity 30%-70%), and will not have the problem of short-term adsorption saturation failure. At the same time, it has excellent flexibility and can be freely deformed with the bending of the wrapping part 1 without bending or cracking. It also does not cause the flow path to be too long, which can ensure that the leaked medium quickly reaches the detection part 2 and maintain the timeliness of the detection response. It is suitable for normal computer rooms, small liquid cooling equipment and other normal humidity scenarios.

[0037] Implementation method with a thickness of 1mm: In this embodiment, the thickness of the moisture-absorbing substrate 31 is 1mm. This thickness takes into account both moisture absorption capacity and detection response speed. It has sufficient moisture absorption capacity and can adapt to the usage requirements of medium and high humidity scenarios (relative humidity 70%-90%). At the same time, it still has good flexibility and fit. The leakage flow path is short and the detection response speed is fast. It is the most versatile implementation method and is suitable for the vast majority of liquid cooling system usage scenarios.

[0038] Implementation method with a thickness of 3mm: In this embodiment, the moisture-absorbing substrate 31 has a thickness of 3mm. This thickness has a large moisture absorption capacity and can be adapted to the use needs of extreme high humidity scenarios (relative humidity above 90%). Even in the rainy season in the south, underground computer rooms and other environments with continuous high humidity, it can stably absorb environmental moisture for a long time without the problem of reverse osmosis due to adsorption saturation. At the same time, the thickness will not reduce the fit with the outer wall of the pipe. It is suitable for high humidity scenarios such as outdoor cabinets and underground data centers.

[0039] The installation process of this product is brief, requiring no multiple wrapping of the detection wire or installation of customized brackets, significantly simplifying the construction steps. The installation time for a single pipe can be reduced to less than 10 seconds, improving installation efficiency by over 90% compared to existing technologies that involve multiple wrapping of the detection wire. During normal operation of the liquid cooling system, the false alarm prevention unit 3 continuously absorbs moisture from the environment and condensation on the pipe surface, keeping the detection electrodes of the detection unit 2 dry, preventing alarms from the external monitoring system. When leakage occurs at the connection of the liquid cooling pipe, coolant seeps out of the pipe wall and quickly contacts the detection electrodes of the detection unit 2 through the conduction path of the false alarm prevention unit 3, making the positive and negative electrodes conductive. The detection unit 2 outputs the corresponding detection signal, and upon receiving the signal, the external monitoring system immediately triggers a leakage alarm, notifying maintenance personnel to handle the situation promptly. When the ambient humidity increases and condensation forms on the pipe surface, the false alarm prevention unit 3 actively absorbs these trace amounts of moisture and locks them inside the structure, preventing free water from contacting the detection electrodes. The output signal of the detection unit 2 remains normal, preventing false alarms and ensuring stable operation of the module in high humidity environments.

[0040] The technical solution of this embodiment solves the problem of poor adaptability of the prior art by means of the adjustable surrounding structure of the wrapping part 1; solves the problem of complicated construction of the prior art by means of the integrated surrounding installation method of the wrapping part 1; and solves the problem of false alarm in high humidity environment by means of the anti-false alarm part 3. The three core technical solutions work together to achieve the unity of universal adaptability, construction convenience and detection reliability, and perfectly solve the core defects of the prior art.

[0041] In this embodiment, the material of the elastic extension part is TPU, namely thermoplastic polyurethane elastomer. The comprehensive properties of this material are highly compatible with the functional requirements of elastic extension and the application scenario of liquid cooling pipeline inspection. Its core advantages are: First, TPU combines the high elasticity of rubber and the high strength of plastic. Its good elastic recovery performance can support the elastic extension part 17 to undergo adaptive deformation with liquid cooling pipelines of different sizes multiple times, and can quickly return to its original position after deformation, ensuring that the wrapping part 1 always fits the outer wall of the pipeline and will not fail due to repeated use, ensuring the continuous adaptability of the module to pipelines of different sizes; Second, TPU has excellent... First, its chemical corrosion resistance prevents it from being corroded by water-based or glycol-based coolants commonly used in liquid cooling systems, thus avoiding swelling and cracking, making it perfectly suited for the operating environment of liquid cooling devices. Second, TPU has good tear and abrasion resistance, which can withstand mechanical friction and collision during installation and construction, and also avoid wear caused by long-term contact with the outer wall of the pipe, ensuring the structural integrity of the elastic extension part 17. Third, TPU material can be molded or integrally formed into the elastic extension part 17, which can be seamlessly connected with the surrounding structure of the wrapping part 1. This method is simple and easy to mass-produce, without the need to adjust the overall structure of the module.

[0042] In this embodiment, the wrapping part 1 is provided with baffles 13 extending in a closed loop along the circumference at both ends of the surrounding structure. The two baffles 13 and the inner sidewall of the wrapping part 1 form an annular anti-leakage groove 14, which is used to receive leakage at the pipe connection.

[0043] In this embodiment, the baffle 13 and the wrapping part 1 are integrally injection molded and extend in a closed loop at both ends along the axial direction of the surrounding structure without any gaps. The height of the baffle 13 is 3mm-5mm, and it extends perpendicular to the inner sidewall of the wrapping part 1 towards the center of the pipe. The distance between the two baffles 13 covers the entire axial length of the liquid cooling pipe joint, ensuring that all the leakage liquid seeping out at the pipe connection falls into the annular anti-leakage groove 14.

[0044] The core working principle of the above structure is as follows: the two closed-loop retaining edges 13 and the inner wall of the wrapping part 1 form a closed annular groove structure, the annular anti-leak groove 14. No matter where the leak occurs at the pipe connection, the leaking coolant will be confined within the annular anti-leak groove 14 and will not overflow from both ends of the wrapping part 1 along the axial direction of the pipe. Its technical effect is reflected in two aspects: First, it avoids detection delays and missed detections caused by leakage overflowing along the pipe axial direction. The annular anti-leak groove 14 can collect all the leakage in the groove, ensuring that the leakage can fully contact the detection part 2. Even a small amount of leakage can be detected by the detection part 2, greatly improving the reliability of leakage detection. Second, it prevents leakage from dripping onto surrounding electrical equipment, causing secondary damage such as short circuits and corrosion, eliminating the safety hazards caused by leakage diffusion in the prior art, and greatly improving the safety of module use.

[0045] Meanwhile, the flange 13 can be integrally formed with the wrapping part 1, which will not affect the inner diameter adjustment function of the wrapping part 1's surrounding structure. It can be adapted to pipes of different diameters and will not increase the difficulty of installation and construction. During installation, it is only necessary to align the annular anti-leakage groove 14 with the axial range of the pipe joint. The operation is simple and does not affect the original construction efficiency. It is suitable for high safety requirements such as industrial liquid cooling systems.

[0046] Example 2 like Figure 4 As shown, the difference between this embodiment and Embodiment 1 lies in the further adjustment of the structure of the wrapping part 1. In this embodiment, a connecting end 15 is provided at one circumferential end of the wrapping part 1, and an adjustable area 16 is provided at the other circumferential end. The connecting end 15 and the adjustable area 16 are detachably coupled to form a closed surround structure. The inner diameter of the surround structure is adjusted by adjusting the relative fixed position of the connecting end 15 and the adjustable area 16. The elastic deformation function of the wrapping part itself can be retained or cancelled, depending on the actual application requirements. In this embodiment, the elastic deformation function of the wrapping part is cancelled. The inventors have found in practice that for leakage detection at pipe connections, it is not necessary to completely seal the pipe connection. Therefore, the inventors have creatively used a surround structure to flexibly change the size by adjusting the relative position of the connecting end and the adjustable area, so that it can be adapted to pipes of different diameters. Whether it is a small-sized liquid cooling pipe or a large-sized liquid cooling pipe, leakage detection can be achieved by adapting and adjusting the wrapping part, which greatly improves the versatility of the module and reduces the additional costs caused by changes in pipe specifications.

[0047] In this embodiment, the adjustable area 16 refers to the functional area on the wrapping part 1 that is used to cooperate with the connecting end 15 and realize the adjustment of the size of the surrounding structure by changing the connection position between the connecting end and the adjustable area. This area extends circumferentially along the wrapping part 1 and its length is not less than 30% of the total length of the wrapping part 1. It can provide sufficient adjustment margin for the inner diameter adjustment of the surrounding structure, so that the module can adapt to liquid cooling pipes of different specifications and cover the most common pipe specifications of industrial and civil liquid cooling systems.

[0048] This embodiment provides two ways of cooperating between the connecting end 15 and the adjustable area 16, which are described below: The first type of connection: adhesive bonding. For example... Figure 4-5As shown, in this embodiment, the connecting end 15 and the adjustable area 16 are connected by an adhesive method. Specifically, a first adhesive layer is provided on the inner side of the connecting end 15, and a second adhesive layer is provided on the outer side of the adjustable area 16. The first adhesive layer and the second adhesive layer are bonded together to achieve fixation. Preferably, the first adhesive layer and the second adhesive layer adopt a hook and loop fastener structure, that is, a hook and loop fastener structure. The inner side of the connecting end 15 is provided with a hook and loop fastener, and the outer side of the adjustable area 16 is provided with a continuous hook and loop fastener along the circumference. Fixation is achieved by bonding the hook and loop fasteners together.

[0049] The core advantages of this adhesive bonding method are: First, it achieves stepless adjustment of the inner diameter of the surrounding structure. The connecting end 15 can be attached to any position in the adjustable area 16 without the need for preset fixed adjustment points, enabling precise adaptation to pipes of any outer diameter and a wider range of compatibility. Second, it is extremely easy to operate. No tools are required; simply press the connecting end 15 onto the corresponding position in the adjustable area 16 to complete the fixation, further shortening the installation time. Third, it can be repeatedly disassembled and reused. The Velcro structure can be repeatedly attached and reattached more than 10,000 times without failing to fix due to repeated disassembly and reassembly. The module can be reused on different pipes, further reducing the cost of use.

[0050] The second type of connection: mechanical snap-fit ​​connection. For example... Figure 6-9 As shown, in this embodiment, the connecting end 15 is provided with a pin buckle or snap fastener male head 151, and the adjustable area 16 is provided with a plurality of connecting holes 161 that are adapted to the pin buckle or snap fastener male head 151 at equal intervals along the circumference. By snapping the pin buckle or snap fastener male head 111 into the connecting holes 121 at different positions, the relative fixed position of the connecting end 15 and the adjustable area 16 can be adjusted, thereby adjusting the inner diameter of the surrounding structure.

[0051] The core advantages of this mechanical snap-fit ​​method are: First, it offers extremely strong connection stability. Through the snap-fit ​​limiting mechanism of the mechanical structure, it can withstand the effects of factors such as pipe vibration, equipment start-up and shutdown, and external force contact during the operation of the liquid cooling system, preventing loosening and ensuring that the wrapping part 1 is tightly attached to the outer wall of the pipe for a long time. This is especially suitable for liquid cooling systems that operate for extended periods in industrial settings. Second, it provides controllable adjustment precision. The connecting holes 121 on the adjustable area 16 are evenly spaced, with a spacing that can be set to 5mm. This allows for precise step-like adjustment of the inner diameter of the surrounding structure, ensuring consistent wrapping tightness for each installation and good consistency in testing results. Third, it offers strong structural durability. The pin buckle or snap-fit ​​structure is integrally molded using the same material as the wrapping part 1, with no easily damaged parts, resulting in a long service life and adaptability to harsh industrial environments such as high temperature, high humidity, and oil contamination.

[0052] In this embodiment, the wrapping part 1 is integrally injection molded from TPU material. The connecting end 15, the adjustable area 16, and the wrapping part 1 are an integrated structure, requiring no secondary assembly, simplifying the manufacturing process, and resulting in high structural strength. After connection and fixation, the surrounding structure is circular, highly compatible with the shape of mainstream circular liquid-cooled pipes, and can perfectly fit the outer surface of the circular pipe, avoiding the gaps caused by non-circular structures. This ensures full contact between the detection part 2 and the pipe connection. Simultaneously, the circular structure experiences uniform stress, and with the elastic fit of the wrapping part 1 material, it can better adapt to minor changes in pipe diameter, maintaining the tightness of the surrounding structure. The detachable connection between the connecting end 15 and the adjustable area 16 ensures a wide range of adjustment for the inner diameter of the surrounding structure while achieving stable and reliable connection and fixation. Furthermore, the installation and operation are simple, allowing for repeated disassembly and reassembly, further improving the module's versatility, ease of construction, and structural stability.

[0053] Specifically, the inner side of the packaging section 1 is provided with a slot structure 17, and the detection section 2 and the false alarm prevention section 3 are both fixed to the packaging section 1 by the slot structure 17.

[0054] In this embodiment, the slot structure 17 refers to a groove-type limiting structure integrally formed on the inner side of the wrapping part 1 and adapted to the outer dimensions of the detection part 2. Its size is strictly adapted to the outer shape of the detection part 2, and the width and depth of the slot are matched with the width and thickness of the detection part 2. It can provide a precise installation positioning reference for the detection part 2, and at the same time realize the quick assembly and disassembly of the detection part 2.

[0055] The slot structure 17 extends in a closed loop along the circumference of the wrapping part 1, maintaining the same shape as the surrounding structure. This allows the detection part 2 to form a closed-loop detection coverage along the circumference of the pipe, avoiding detection blind spots. During installation, the detection part 2 can be fixed simply by pushing it into the slot along its extension direction. During disassembly, the detection part 2 can be directly pulled out of the slot without the need for tools or damaging parts, significantly reducing the maintenance and replacement costs of the detection part 2. This is especially suitable for scenarios where the detection part 2 needs to be calibrated or replaced periodically.

[0056] The core advantages of this slot-type fixing method are as follows: First, precise positioning. The slot structure 17 provides a fixed installation benchmark for the detection part 2, effectively preventing displacement or tilting during installation, ensuring the fit between the detection part 2 and the pipe connection, guaranteeing no blind spots in detection coverage, and ensuring good consistency in installation position each time, resulting in stable detection effects. Second, convenient assembly and disassembly. No additional operations such as bonding or welding are required; the installation and disassembly of the detection part 2 can be completed manually, significantly improving construction and maintenance efficiency. Third, good protection. The slot structure 17 can form a protective wrap around the side of the detection part 2, preventing the detection part 2 from directly rubbing against the outer wall of the pipe and the wrapping part 1, preventing performance failure due to wear, and extending the service life of the detection part 2. Fourth, strong structural compatibility. The slot structure 17 and the wrapping part 1 are integrally formed, requiring no additional connecting parts, not increasing the overall thickness of the wrapping part 1, and not affecting the inner diameter adjustment function of the wrapping part 1's surrounding structure. It can be perfectly adapted to various wrapping part structures of this invention.

[0057] In this embodiment, the inner side plate 171 of the slot structure 17 has a plurality of liquid passage holes 18, which extend along the thickness direction of the inner side plate 171 to allow leakage at the pipe connection to permeate to the detection unit 2. The liquid passage holes 18 are circular through holes, evenly distributed at equal intervals along the circumference of the slot structure 17, with a hole spacing of 10 mm and a hole diameter of 3 mm. This ensures that leakage at any location at the pipe connection can quickly permeate through the corresponding liquid passage holes 18 without compromising the overall strength of the slot structure 17, thus ensuring that the positioning and fixing effect of the slot on the detection unit 2 is not affected.

[0058] Example 3 like Figure 10-12 As shown, the main difference between this embodiment and Embodiment 1 is that the wrapping part 1 is an elastically rolled structure in its natural state. The external force can make the elastically rolled structure overcome the elastic force and form an unfolded state. When the force is withdrawn, the wrapping part 1 automatically changes from the unfolded state to the rolled state and forms a closed wrapping structure.

[0059] In this embodiment, the elastic roll-up structure refers to a structure that maintains a closed, rolled-up tubular shape under natural conditions without external force. Under external force, it can overcome its own elastic force and unfold into a straight, strip-like unfolded state. After the external force is removed, it can automatically restore its original rolled-up shape by relying on its own elastic restoring force. It can automatically wrap and fix the liquid cooling pipe without the need for additional reset mechanism, connecting parts, or fixing structure. This is the core innovation of this embodiment.

[0060] Specifically, in this embodiment, the wrapping part 1 is an open self-rolling textile sleeve structure, which is integrally formed by textile weaving process using polyester or polyamide material. In its natural state, it maintains a closed rolled tube shape. Its opening can be pried open to both sides under the action of external force to form a straight unfolded state. After the external force is removed, it automatically restores the rolled shape by relying on the internal stress of the textile weaving structure itself to form a surrounding structure that wraps the tube.

[0061] The open-ended self-winding textile structure referred to here is a tubular structure with unidirectional internal stress formed by weaving polyester or polyamide multifilaments. Its structural characteristics are similar to those of common spiral wound electrical wire sheaths, possessing excellent self-winding properties, flexibility, and abrasion resistance. In this embodiment, the polyester material, also known as polyester fiber, has excellent chemical corrosion resistance, abrasion resistance, and aging resistance. It can stably contact the water-based and glycol-based coolants commonly used in liquid cooling systems for a long time without swelling, aging, or performance degradation. At the same time, it has excellent insulation properties and will not interfere with the electrical signals of the detection unit 2, meeting the electrical safety requirements for liquid cooling equipment. The polyamide material, also known as nylon, has higher elasticity and flexibility, better self-winding effect, and can more tightly adhere to the outer wall of the pipe. It also has better impact resistance and low-temperature resistance, making it suitable for the use of liquid cooling systems in low-temperature environments.

[0062] The core advantages of this purely elastic textile structure are: First, the installation is extremely simple. During construction, only the opening of the wrapping part 1 needs to be pried open with external force, placed on the connection of the liquid cooling pipe, and then released. The wrapping part 1 will automatically roll up and tightly wrap the pipe. The entire installation process takes only a few seconds and requires no fixing operation, which greatly improves construction efficiency compared with existing technologies. Second, it has excellent self-adaptability. The self-rolling tension of the wrapping part 1 can be automatically adjusted according to the outer diameter of the pipe. No adjustment operation is required, and it can tightly fit the outer wall of pipes with different outer diameters, with excellent universal adaptability. Third, it has strong structural stability. The textile structure has excellent fatigue resistance and can be repeatedly unfolded and rolled up more than 100,000 times without structural failure. There will be no problem of elastic decay after long-term use, and the service life is extremely long. Fourth, the production process is mature. The open self-rolling textile sleeve is a mature industrial product with a standardized production process. There is no need for separate mold customization, the production cost is extremely low, and it is easy to promote large-scale mass production.

[0063] When an open-ended self-winding textile sleeve structure is used, the detection section 2 can be selected as a liquid-cooled detection line, and the detection section 2 and the wrapping section 1 are fixedly connected by a braiding method. The fixed connection by braiding method mentioned here means that during the textile weaving process of the wrapping section 1, the liquid-cooled detection line and the polyester or polyamide multifilament of the wrapping section 1 are interwoven and tightly woven to form an integrated structure with the wrapping section 1. The liquid-cooled detection line is evenly distributed on the inner side of the wrapping section 1 after it is rolled up.

[0064] The core advantages of this braided connection method are as follows: First, it offers extremely strong connection stability. The liquid-cooled detection line and the wrapping part 1 are integrated through braiding, resulting in a bonding force far superior to simple adhesive or binding methods. This effectively prevents the liquid-cooled detection line from shifting, falling off, or warping during installation, use, and operation of the liquid-cooling device, ensuring that the detection part 2 remains in the preset detection position. Second, it provides comprehensive detection coverage. The braiding process allows the liquid-cooled detection line to form a uniform circumferential distribution inside the wrapping part 1, achieving full coverage of the pipe connection and avoiding blind spots caused by localized aggregation of the liquid-cooled detection line. Third, it does not affect the structural performance of the wrapping part 1. The braided liquid-cooled detection line maintains good flexibility and can deform freely with the unfolding and rolling of the wrapping part 1 without increasing the overall thickness of the wrapping part 1 or affecting its self-rolling effect and fit. Fourth, it offers high production efficiency. The braided connection can be completed simultaneously during the textile production of the wrapping part 1, eliminating the need for additional assembly steps, significantly improving the overall production efficiency of the detection module and reducing assembly costs.

[0065] In addition, the false alarm prevention unit 3 can also be fixed to the package part 1 by similar fastening methods such as weaving or bonding, and the liquid-cooled detection line is located between the false alarm prevention unit 3 and the package part 1.

[0066] Example 4 The main difference between this embodiment and Embodiment 3 is the use of a composite skeleton roll structure, similar to a snap ring structure. In this embodiment, the wrapping part includes a roll skeleton and a connecting sleeve. The roll skeleton is a highly elastic metal sheet, and the connecting sleeve wraps around the outside of the roll skeleton. The wrapping part is naturally curled up. After being opened outward by a first external force, it forms a straight, unfolded state. After being subjected to a second external force, it returns to its curled shape and forms a surrounding structure that fits the dimensions of the liquid cooling pipe connection.

[0067] Specifically, the coiled skeleton is made of highly elastic spring steel or stainless steel sheets with a thickness of 0.1mm-0.3mm. It provides stable and durable elastic support for the wrapping part and is the core component for realizing the coiling function. In its natural state, it is pre-formed into a coiled ring shape. After being bent outward, it can form a straight strip structure. When stimulated by a second external force such as slapping, it will quickly return to its original coiled shape, which is the structural principle of common slap rings and slap rulers. The connecting sleeve is made of insulating and corrosion-resistant flexible materials, such as silicone rubber and TPU, and tightly wraps around the outside of the coiled skeleton. On the one hand, it provides insulation to prevent the metal coiled skeleton from directly contacting the coolant and detection part, which could cause corrosion or electrical short circuits. On the other hand, it provides corrosion protection and anti-slip function, improving the adhesion friction between the wrapping part and the outer wall of the pipe, while protecting the coiled skeleton from external environmental corrosion and extending its service life.

[0068] In this embodiment, the first external force refers to the force exerted by the operator to pry open the wrapped part outward, changing it from a curled state to a straight, unfolded state. This force needs to overcome the elastic internal stress of the rolled frame, causing the straight metal sheet to undergo plastic deformation and maintain its unfolded state. The second external force refers to the force exerted by the operator to adhere the unfolded wrapped part to the outer wall of the pipe and gently pat the back of the wrapped part. This force will break the straight deformation balance of the metal sheet, causing the rolled frame to quickly restore its original curled shape by relying on its own elastic internal stress, thus completing the wrapping of the pipe.

[0069] The core advantages of this composite skeleton roll structure are as follows: First, it combines structural rigidity and elasticity. The roll skeleton of highly elastic metal sheets provides durable and stable elastic support for the wrapping part. Long-term repeated use will not result in elastic decay or plastic deformation, and its service life is far longer than that of purely elastic material structures. It is especially suitable for liquid cooling systems that require frequent disassembly and maintenance. Second, it achieves higher wrapping tightness. The metal skeleton has stronger elastic recovery force, enabling sufficient wrapping tightness for large-diameter liquid cooling pipes. The fit is significantly improved, forming a more regular surrounding structure that ensures full circumferential contact between the detection part and the pipe connection, avoiding detection blind spots. Furthermore, it is applicable to a wider range of pipe sizes. Third, it has strong impact and vibration resistance. The high structural strength of the metal skeleton can withstand minor vibrations and collisions during the operation of the liquid cooling device, reducing the possibility of structural damage and further ensuring the stability of the detection module. It is suitable for more complex industrial liquid cooling equipment application scenarios.

[0070] Based on Embodiment 1, the technical solution of this embodiment achieves automatic wrapping of the wrapping part 1 through the design of an elastic rolling structure, without the need for any fixing structure or adjustment operation, further simplifying the installation steps and improving construction efficiency. At the same time, it can adaptively adapt to liquid cooling pipes of different outer diameters, with stronger universal adaptability, and the structural stability and service life are also greatly improved.

[0071] Example 5 The difference between this embodiment and Embodiment 1 is that the elastic extension portion is an independent structural area on the wrapping portion, integrally formed with the main body of the wrapping portion, accounting for 40%-60% of the total length of the wrapping portion.

[0072] Example 6 This embodiment is a further optimization of the module's false alarm prevention system based on Embodiment 1. In this embodiment, a signal processing unit electrically connected to the detection unit is also included. The signal processing unit has preset condensation threshold and leakage threshold. The signal processing unit is used to distinguish between pipeline condensation and actual leakage based on the amplitude and rate of change of the detection signal, and outputs the corresponding alarm signal.

[0073] In this embodiment, the signal processing unit uses a microcontroller (MCU) as its core and has built-in signal sampling circuit, arithmetic circuit and signal output circuit. The signal sampling circuit is electrically connected to the detection electrodes of the detection unit, and can collect the resistance change signal between the detection electrodes in real time, convert it into the corresponding digital level signal, and transmit it to the MCU for arithmetic processing.

[0074] Amplitude refers to the level change of the detection signal output by the detection unit 2, reflecting the degree of conduction between the detection electrodes; rate of change refers to the amount of change of the detection signal per unit time, reflecting the speed of conduction between the electrodes; condensation threshold and leakage threshold are pre-set critical values ​​of the detection signal used to distinguish between condensation and actual leakage in the pipeline. The condensation threshold is the critical value that distinguishes between normal dryness and condensation, and the leakage threshold is the critical value that distinguishes between condensation and actual leakage. They can be flexibly adjusted according to different usage scenarios and coolant types.

[0075] The core working principle of this embodiment is as follows: Normal condensation on the pipe surface is a slow formation process, resulting in a low rate of change and a low amplitude in the detection signal, which will not exceed the leakage threshold. However, when a pipe actually leaks, the leaking medium quickly contacts the detection electrode, resulting in a high rate of change and a rapid increase in amplitude in the detection signal, exceeding the leakage threshold. By simultaneously judging both the amplitude and rate of change of the detection signal, the signal processing unit can effectively filter out abnormal signals caused by environmental interference and pipe condensation, thus avoiding false alarms.

[0076] The specific judgment logic is as follows: When the amplitude of the detection signal is lower than the condensation threshold, it is determined that the pipeline is in a normal drying state, the signal processing unit outputs a normal operation signal, and there is no alarm. When the amplitude of the detected signal is higher than the condensation threshold but lower than the leakage threshold, and the rate of signal change is lower than the preset rate threshold, it is determined that condensation is occurring on the pipe surface. The signal processing unit outputs a condensation warning signal and does not trigger a leakage alarm. When the amplitude of the detected signal is higher than the leakage threshold and the rate of signal change is higher than the preset rate threshold, it is determined that there is a real leakage in the pipeline. The signal processing unit immediately outputs a leakage alarm signal and transmits it to the external monitoring system via wired or wireless means.

[0077] The technical solution of this embodiment, based on the mechanical structure anti-false alarm function of Embodiment 1, adds an electrical identification anti-false alarm function, constructing a dual anti-false alarm system of "mechanical structure + electrical identification". This makes up for the performance limitations of relying solely on the mechanical structure under extreme working conditions. It can effectively filter abnormal signals under extreme working conditions such as sudden increase in ambient humidity, large amount of condensation caused by excessive temperature difference between the inside and outside of the pipeline, and strong electromagnetic interference in industrial scenarios, further reducing the probability of false alarms. Even in complex industrial environments, it can stably distinguish between pipeline condensation and actual leakage, greatly improving the detection reliability of the module and expanding the applicable scenarios of the module.

[0078] Example 7 like Figure 13 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the first connecting end 11 and the second connecting end 12 of the wrapping part are both located inside the surrounding structure. This layout has the following core advantages: First, it can prevent the connecting ends from being exposed to external bumps and friction, prevent the connection structure from failing due to external force damage, and extend the service life of the connecting ends; Second, the inner layout of the connecting ends makes them secondary restrained by the outer wall of the pipe after wrapping the pipe, further improving the stability of the connection between the first connecting end 112 and the second connecting end 113, and effectively preventing them from loosening during equipment operation and pipe vibration.

[0079] Example 8 like Figure 14-15 As shown, the leakage detection module provided in this embodiment differs from the leakage detection module with mechanical snap-fit ​​connection in Embodiment 2 in that the connecting end 15 of the wrapping part 1 and the adjustable area 16 are connected by a snap-fit ​​method.

[0080] Example 9 like Figure 16-17 As shown, the leakage detection module provided in this embodiment differs from the leakage detection module with mechanical buckle connection in Embodiment 2 in that the connecting end 15 of the wrapping part 1 is connected to the adjustable area 16 in a buckle-like manner similar to a watch strap.
