[0007] A sensor is used to detect the deformation of the elastic element in order to determine the leakage of the water channel to be detected.

[0008] When leakage occurs in the water channel to be tested, the elastic element moves in the direction of restoring deformation.

[0011] In one embodiment, the mounting base includes a base and a top cover, the mounting opening and the inner cavity are formed in the base, and the connecting portion is sealed between the base and the top cover.

[0012] In one embodiment, the base is provided with a mounting groove, and the mounting opening is located on the bottom wall of the mounting groove.

[0013] In one embodiment, the leakage detection device further includes a guide bracket, through which the deformable part is movably mounted to the mounting port.

[0014] In one embodiment, the guide bracket includes a support platform and a guide rod laterally connected to the support platform. The support platform is fixedly connected to the deformable part, and the guide rod passes through the mounting port.

[0015] In one embodiment, the elastic element is connected to the base and is located between the deformable portion and the base.

[0016] In one embodiment, the base is provided with a limiting ring groove outside the mounting port, the elastic element is fitted onto the guide rod, one end of which is located in the limiting ring groove, and the other end abuts against the deformable part.

[0017] In one embodiment, the support platform and the deformable part are injection molded as a single unit;

[0018] And / or, the elastic moving part is configured as a silicone part.

[0019] In one embodiment, the elastic element is disposed on the side of the elastic movable element opposite to the base and is fixedly connected to the upper cover.

[0020] In one embodiment, the elastic element is configured as a spring sheet, the spring sheet including a connecting ring and an elastic sheet connected to the inner side of the connecting ring, the connecting ring being fixedly connected to the outer surface of the upper cover, and the elastic sheet being fixedly connected to the guide bracket.

[0021] In one embodiment, the elastic element is connected between the upper cover and the elastic movable element.

[0022] In one embodiment, one of the base and the connecting portion is provided with at least one first limiting groove, and the other is provided with a first limiting protrusion that cooperates with the first limiting groove;

[0023] And / or, one of the upper cover and the connecting portion is provided with at least one second limiting protrusion, and the other is provided with a second limiting groove that cooperates with the second limiting protrusion.

[0029] In the technical solution of this invention, the leakage detection device can be installed in the water circuit to be detected, specifically in the water-cooled circulation pipeline. During installation, the elastic element is first deformed by external force pre-compression, moving towards the direction close to the installation port. The inner cavity is connected to the water circuit to be detected, forming a closed loop. Then, the external force pre-compression is released. When no leakage occurs, the pressure in the inner cavity and the total elastic restoring force of the elastic element are maintained in a negative pressure balance state, ensuring that the elastic element remains in a state of pressure deformation. When leakage occurs, the external atmospheric pressure enters the closed loop, disrupting the original pressure balance, causing the elastic element to move in the direction of restoring deformation. This change is detected by the sensor, realizing rapid and conspicuous detection of coolant leakage and issuing an alarm in a timely manner to prompt the user to take appropriate measures. This can effectively ensure the normal operation of the equipment heat dissipation system, reduce the risk of equipment failure caused by coolant leakage, and effectively improve the detection accuracy and sensitivity of the leakage detection device.

[0030] In addition, since the water circuit under test is under negative pressure, even if there are tiny cracks in the water circuit under test, the coolant is unlikely to leak out. Instead, the surrounding air will be drawn into the water circuit under test due to atmospheric pressure, thus avoiding unnecessary loss of coolant and reducing the risk of leakage.

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0052] Coolant plays a crucial role in the heat dissipation systems of numerous mechanical and electronic devices. To ensure safe operation, sealing structures are typically installed at pipe joints to prevent leaks, and regular maintenance is required. However, traditional coolant leak detection methods rely primarily on visual inspection, which can easily overlook leaks in hidden corners or fail to detect small leaks, significantly reducing the accuracy of detection and posing safety hazards to equipment operation, resulting in unnecessary economic losses.

[0053] To solve this technical problem, the present invention proposes a leakage detection device 1, which can be specifically applied to computer water cooling radiators.

[0054] Please see Figure 1 , Figure 2 and Figure 6In one embodiment of the present invention, the leakage detection device 1 includes a mounting base 10, an elastic element, and a sensor. The mounting base 10 has an inner cavity 111 and a mounting port 112 communicating with the inner cavity 111. The inner cavity 111 is used to communicate with the water channel 2 to be detected. The elastic element is sealed and installed in the mounting port 112 and is used to provide an elastic restoring force that counteracts the pressure of the inner cavity 111. The sensor is used to detect the deformation of the elastic element to determine the leakage situation of the water channel 2 to be detected. When the water channel 2 to be detected leaks, the elastic element moves in the direction of restoring deformation. This improves the detection accuracy and detection sensitivity of the leakage detection device 1.

[0055] In the technical solution of this invention, the leakage detection device 1 can be installed in the water circuit 2 to be detected, specifically in the water-cooled circulation pipeline. During the installation process, the elastic element is first deformed by external force pre-compression, moving towards the direction close to the installation port 112. The inner cavity 111 is connected to the water circuit 2 to be detected, forming a closed loop. Then, the external force pre-compression is released. When there is no leakage, the pressure in the inner cavity 111 and the total elastic restoring force of the elastic element are maintained in a negative pressure balance state, ensuring that the elastic element remains in a state of pressure deformation. When leakage occurs, the external atmospheric pressure enters the closed loop, disrupting the original pressure balance, allowing the elastic element to move in the direction of restoring deformation. This change is detected by the sensor, realizing rapid and conspicuous detection of coolant leakage and issuing an alarm in time to prompt the user to take corresponding measures. This can effectively ensure the normal operation of the equipment heat dissipation system, reduce the risk of equipment failure caused by coolant leakage, and effectively improve the detection accuracy and sensitivity of the leakage detection device 1.

[0056] In addition, since the inside of the water channel 2 under test is under negative pressure, even if there are tiny cracks in the water channel 2 under test, it is difficult for the coolant to leak out. Instead, the surrounding air will be drawn into the water channel 2 under test due to atmospheric pressure, thereby avoiding unnecessary loss of coolant and reducing the risk of leakage.

[0057] It should be emphasized that the leak detection device 1 can detect and promptly respond to any leak in the water channel 2 under test, regardless of which part leaks, achieving comprehensive detection and improving detection accuracy. Furthermore, even if the leak in the water channel 2 is small, it will cause the internal pressure of the water channel 2 to approach atmospheric pressure in a short time. This will cause the water channel 2 to move away from the installation port 112 under the elastic restoring force of the elastic element. The sensor will also promptly respond to the change in the deformation part 22 of the elastic moving part 20, which facilitates quick judgment of whether there is a leak in the water channel 2 under test and helps to improve the detection sensitivity of the leak detection device 1.

[0058] Optionally, in an embodiment of the present invention, the elastic element includes a movable member and an elastic member 30. The movable member is sealed and installed in the mounting port 112 and connected to the elastic member 30. It can be understood that the movable member can serve as a seal at the mounting port 112 to form a negative pressure chamber in the inner cavity 111, thereby reducing the possibility of leakage at the mounting port 112.

[0059] The elastic element 30 possesses elastic properties, enabling it to deform or recover its original shape under external force. This gives the elastic element an elastic restoring force that counteracts the pressure in the inner cavity 111, allowing it to maintain a negative pressure balance when no leakage occurs. This elastic restoring force balances the pressure in the inner cavity 111 to ensure normal coolant circulation. Furthermore, in the event of leakage, because the movable part is connected to the elastic element 30, and the elastic element 30 is connected to the mounting base 10, the elastic element 30, during its recovery deformation, pushes the movable part away from the mounting port 112 relative to the mounting base 10. This allows the sensor to detect the deformation of the elastic element through the movement of the movable part, thereby determining the leakage status of the water path 2 under test. The elastic element 30 can be configured as a spring, sheet spring, tension spring, or other elastic structure.

[0060] Please see Figure 5 and Figure 9 In an embodiment of the present invention, the movable member is configured as an elastic movable member 20, the elastic movable member 20 including a connecting part 21 and a deformable part 22, the connecting part 21 being fixed to the mounting base 10, the deformable part 22 covering the mounting opening 112 and being connected to the elastic member 30.

[0061] Specifically, the elastic element includes an elastic movable member 20 and an elastic member 30. The elastic movable member 20 includes a connecting part 21 and a deformable part 22. The connecting part 21 can be sealed and fixed to the mounting base 10 by means of hot-melt welding, embedded connection, etc., so as to form a negative pressure in the inner cavity 111 and the water channel, thereby allowing the coolant to be smoothly drawn into the pump, thus completing the entire coolant circulation process. The deformable part 22 is a structure on the elastic movable member 20 that deforms in conjunction with external force.

[0062] Thus, when no leakage occurs, the pressure in the inner cavity 111 and the total elastic restoring force of the elastic movable element 20 and the elastic element 30 are maintained in a negative pressure balance. When leakage occurs, the external atmospheric pressure enters the closed loop, disrupting the original pressure balance. Both the elastic element 30 and the elastic movable element 20 recover their deformation. Since the elastic element 30 is connected to the deformation part 22, the elastic element 30 can also act on the deformation part 22, causing the deformation part 22 to move rapidly in the direction of recovery deformation. This direction of recovery deformation can be away from the inner cavity 111 and the mounting port 112, so that this change can be detected by the sensor, achieving rapid and conspicuous detection of coolant leakage and improving the detection sensitivity of the leakage detection device 1. The elastic movable element 20 can be made of materials such as rubber or silicone. In this embodiment, the elastic movable element 20 is configured as a silicone element, specifically a silicone diaphragm. However, this design is not limited to this; in other embodiments, the elastic element only includes the elastic movable element 20.

[0063] Taking the elastic element including the elastic moving part 20 as an example, there are many specific implementations of the above-mentioned sensor. This invention only lists some embodiments. Other sensors that can detect the deformation of the elastic element are still within the scope of protection of this case.

[0064] In some embodiments of the present invention, the sensor may be configured as at least one of a pressure sensor, a stroke sensor, or a Hall sensor. The sensor can be fixed to the mounting base 10 via a circuit board 50 and electrically connected to a computer control system, facilitating the sensor to send detection signals to the control system. Upon receiving the detection signal, the control system can alert the user to a leakage problem via a display or speaker.

[0065] Understandably, when the sensor is configured as a stroke sensor, the amount of displacement of the deformable part 22 is detected to determine whether the water path 2 under test is leaking. Specifically, the displacement of the deformable part 22 can be determined by the change in the distance between the sensor probe and the deformable part 22, or by the change in capacitance, resistance or light intensity. At this time, the water path 2 under test is leaking.

[0066] When the sensor is configured as a pressure sensor, the probe of the pressure sensor can directly contact the deformable part 22, or there can be a certain distance between the probe and the deformable part 22, so that when leakage occurs, the deformable part 22 moves away from the mounting port 112 and gradually recovers its deformation, causing a change in the pressure applied to the probe, or the deformable part 22 contacts the probe during the process of recovering its deformation, so that the probe senses the pressure, and then the leakage of the water circuit 2 under test can be determined by the detected pressure value change.

[0067] When the sensor is configured as a Hall sensor, the deformation part 22 is made of magnetoelastic material, or a magnet to be detected is provided on the deformation part 22. When the deformation part 22 deforms under pressure, the magnetic field where the deformation part 22 is located changes, and the leakage of the water channel 2 to be detected is determined by the change of the magnetic field.

[0068] Please see Figures 3 to 5 , Figures 7 to 9 In an embodiment of the present invention, the mounting base 10 includes a base 11 and a top cover 12. The mounting port 112 and the inner cavity 111 are formed on the base 11. The connecting part 21 is sealed between the base 11 and the top cover 12. In this way, the elastic movable member 20 can be stably assembled on the mounting base 10, and the elastic movable member 20 can seal the mounting port 112, ensuring the formation of the negative pressure inner cavity 111.

[0069] Since the mounting port 112 and the inner cavity 111 are formed on the base 11, the base 11 can be a three-way pipe or a two-way pipe. Then, one pipe port on the base 11 is configured as the mounting port 112, and the other pipe ports can be connected to the connectors on the water circuit 2 to be tested, so as to realize the assembly of the leakage detection device 1 on the water circuit 2 to be tested and the leakage detection.

[0070] Specifically, in an embodiment of the present invention, the upper cover 12 and the base 11 are connected by fasteners, which can be screws or clips. When the fastener is a screw, such as... Figure 5 As shown, one of the upper cover 12 and the base 11 has a positioning protrusion with a first positioning through hole, and the other has a positioning groove that matches the positioning protrusion with a second positioning through hole that mates with the first positioning through hole. A fastener passes through the first positioning through hole and is locked in the second positioning through hole, thus achieving positioning and relative fixation between the upper cover 12 and the base 11. However, in other embodiments, one of the upper cover 12 and the base 11 has a first positioning through hole, and the other has a second positioning through hole that mates with it.

[0071] Please see Figure 5 and Figure 9 In an embodiment of the present invention, the base 11 is provided with a mounting groove 113, and the mounting opening 112 is provided on the bottom wall of the mounting groove 113. Thus, the mounting groove 113 provides deformable space for the elastic movable member 20. Under the action of external force, the deformable part 22 of the elastic movable member 20 can move toward the mounting opening 112, or even fit against the bottom wall of the mounting groove 113 to complete the pre-pressurization operation, thereby ensuring that the leakage detection device 1 is in a negative pressure balance state when no leakage occurs.

[0072] Optionally, in an embodiment of the present invention, the leakage detection device 1 further includes a guide bracket 40, and the deformable part 22 is movably mounted on the mounting port 112 through the guide bracket 40. Thus, the connection between the deformable part 22 and the guide bracket 40 can effectively enhance the structural stability of the deformable part 22, reduce the risk of excessive deformation or even failure of the deformable part 22, and extend the service life of the elastic moving part 20. Furthermore, through the guiding cooperation between the guide bracket 40 and the mounting port 112, the pressure of the inner cavity 111 can be directly applied to the guide bracket 40, thereby enabling the deformable part 22 to move up and down axially in the mounting port 112, realizing the response of the deformable part 22 to the pressure change in the inner cavity 111, and facilitating accurate detection by the sensor.

[0073] Specifically, in an embodiment of the present invention, the guide bracket 40 includes a support platform 41 and a guide rod 42 laterally connected to the support platform 41. The support platform 41 is fixedly connected to the deformable part 22, and the guide rod 42 passes through the mounting port 112. It is understood that the support platform 41 and the guide rod 42 can be fixed into a whole by means of integral injection molding, welding, threaded connection, etc. The support platform 41 and the deformable part 22 can be connected by means of bonding, injection molding, etc., specifically fixed in the central region of the deformable part 22. Other regions, such as the deformable region located between the central region and the connecting part 21, can deform in response to pressure changes. Specifically, the deformable part 22 in the central region moves closer to or away from the mounting port 112 under pressure, while the deformable part 22 in the deformable region deforms accordingly to ensure the reliability of the movement. However, in other embodiments, the guide bracket 40 may only include the guide rod 42.

[0074] In this embodiment, the support platform 41 and the deformation part 22 are injection molded as one piece. At this time, the support platform 41 is provided with injection molding through holes, which can increase the effective connection area between the support platform 41 and the deformation part 22, thereby further improving the connection strength between the guide bracket 40 and the elastic movable part 20.

[0075] Please see Figures 2 to 5 In an embodiment of the present invention, the elastic element 30 is connected to the base 11 and is located between the deformable part 22 and the base 11. In this way, when leakage occurs, the elastic element 30 assists the deformable part 22 to move away from the mounting port 112 until it recovers its deformation. Then, the sensor can confirm the leakage of the water circuit 2 under test by detecting the displacement change, pressure change, or magnetic field change of the deformable part 22, and then prompt the user to take appropriate measures.

[0076] Specifically, in an embodiment of the present invention, the base 11 is provided with a limiting annular groove 114 outside the mounting port 112. The elastic member 30 is fitted onto the guide rod 42, with one end located within the limiting annular groove 114 and the other end abutting against the deformable part 22. Furthermore, due to the provision of the limiting annular groove 114 and the structural reinforcement of the deformable part 22 by the support platform 41, the elastic member 30 can reliably press against the base 11 and the deformable part 22 when no leakage occurs, ensuring the force of the elastic member 30 is maintained. This assists the elastic movable member 20 in quickly recovering its deformation when leakage occurs, improving the detection accuracy and sensitivity of the sensor. The elastic member 30 can be configured as a spring 31 or an elastic sleeve. Of course, in other embodiments, the support platform 41 may expose the deformable part 22 and provide an annular groove for mounting the other end of the elastic member 30.

[0077] Please see Figures 6 to 9 In an embodiment of the present invention, the elastic element 30 is disposed on the side of the elastic movable element 20 away from the base 11 and is fixedly connected to the upper cover 12. In this way, when leakage occurs, the elastic element 30 assists the deformation part 22 to move away from the mounting port 112 until it recovers its deformation. Then, the sensor confirms the leakage of the water channel 2 under test by detecting the displacement change, pressure change, or magnetic field change of the deformation part 22, and prompts the user to take appropriate measures.

[0078] Specifically, in an embodiment of the present invention, the elastic element 30 is configured as a spring sheet 32, which includes a connecting ring 321 and an elastic sheet 322 connected to the inner side of the connecting ring 321. The connecting ring 321 is fixedly connected to the outer surface of the upper cover 12, and the elastic sheet 322 is fixedly connected to the guide bracket 40. Thus, the external placement of the elastic element 30 helps to simplify the internal structure of the base 11 and facilitates the processing of the base 11. Furthermore, since the spring sheet 32 ​​is connected to the guide bracket 40 through the elastic sheet 322, the elastic sheet 322 can reliably press against the deformation part 22 when there is no leakage, ensuring that the force of the elastic element 30 is maintained. In the event of leakage, this assists the elastic movable element 20 to quickly recover its deformation, thereby improving the detection accuracy and sensitivity of the sensor.

[0079] The outer surface of the top cover 12 is provided with multiple mounting posts along its circumference. Each mounting post is provided with multiple first mounting holes. The connecting ring 321 is provided with a second mounting hole that mates with the first mounting holes. The second mounting hole is a threaded hole, which allows the fastener to pass through the second mounting hole and lock into the first mounting hole after the connecting ring 321 is mounted on the mounting post, thus completing the assembly of the spring piece 32.

[0080] The elastic sheet 322 is in the shape of a disc spiral, which makes it easy to deform with the deformation part 22 when the external force is pre-pressed, and to maintain the force of the elastic element 30 when there is no leakage, so as to help the elastic moving part 20 to quickly recover its deformation when leakage occurs, thereby improving the detection accuracy and detection sensitivity of the sensor.

[0081] To allow the elastic sheet 322 to deform in accordance with the deformation of the deformable part 22, the elastic sheet 322 is provided with a first connecting hole 323, and the guide bracket 40 is provided with a second connecting hole 411. Fasteners pass through the first connecting hole 323 and are fixed within the second connecting hole 411, thereby fixing the elastic sheet 322 to the elastic movable member 20 as a whole via the guide bracket 40. When the guide bracket 40 includes a support platform 41 and a guide rod 42, the second connecting hole 411 is formed in the support platform 41, which is exposed on the end face of the deformable part 22 facing the upper cover 12. Alternatively, the deformable part 22 may have a clearance hole 221 corresponding to the second connecting hole 411, thus ensuring the fixed connection between the elastic sheet 322 and the guide bracket 40. However, in other embodiments, the elastic member 30 may be configured as a tension spring.

[0082] Optionally, in another embodiment of the present invention, the elastic element 30 is connected between the upper cover 12 and the elastic movable element 20. In this way, while ensuring the sealing effect of the elastic movable element 20 on the mounting port 112, the elastic element 30, such as the spring sheet 32, is placed between the upper cover 12 and the deformable part 22, which also enables the elastic element 30 to maintain force to assist the elastic movable element 20 in restoring its deformation.

[0083] Please see Figure 5 and Figure 9 In an embodiment of the present invention, one of the base 11 and the connecting portion 21 is provided with at least one first limiting groove 115, and the other is provided with a first limiting protrusion 211 that cooperates with the first limiting groove 115. In this way, the interlocking of the first limiting groove 115 and the first limiting protrusion 211 helps to increase the effective connection area between the base 11 and the connecting portion 21, while increasing the difficulty of coolant leakage from the connection between the base 11 and the connecting portion 21, thereby improving the sealing effect between the base 11 and the connecting portion 21.

[0084] Please see Figure 5 and Figure 9 In an embodiment of the present invention, one of the upper cover 12 and the connecting portion 21 is provided with at least one second limiting protrusion 121, and the other is provided with a second limiting groove 212 that cooperates with the second limiting protrusion 121. In this way, the interlocking of the second limiting groove 212 and the second limiting protrusion 121 helps to increase the effective connection area of ​​the upper cover 12 and the connecting portion 21, thereby improving the connection strength of the upper cover 12 and the connecting portion 21.

[0085] In addition, when there is an assembly gap between the outer edge of the elastic movable member 20 and the base 11, the second limiting protrusion 121 can also be provided in the assembly gap to further increase the difficulty of coolant leakage from the connection between the base 11 and the connecting part 21 and improve the sealing effect between the base 11 and the connecting part 21.

[0086] Optionally, in an embodiment of the present invention, a circuit board 50 is also fixed on the upper cover 12, and the sensor is electrically connected to the circuit board 50 to ensure the reliability of the sensor. The circuit board 50 and the upper cover 12 can be detachably connected by means of screws, clips, or other methods, thus facilitating the removal of the circuit board 50 before applying external pre-pressure and its reinstallation on the upper cover 12 after the external pre-pressure is released.

[0087] Please see Figure 3 In an embodiment of the present invention, the upper cover 12 is provided with a positioning post 122, and the circuit board 50 is provided with a positioning hole 51 that cooperates with the positioning post 122. Thus, the cooperation between the positioning post 122 and the positioning hole 51 facilitates the rapid assembly of the circuit board 50 and the upper cover 12. For example, taking the upper cover 12 and the circuit board 50 as a fixed connection achieved by screws, the upper cover 12 is provided with a first fixing hole, and the circuit board 50 is provided with a second fixing hole. Through the insertion and cooperation of the positioning post 122 and the positioning hole 51, the first fixing hole and the second fixing hole can be quickly aligned, facilitating the tightening of the screws. Of course, in other embodiments, the first fixing hole may be formed on the positioning post 122, in which case the positioning hole 51 becomes the second fixing hole.
