Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of leakage detection, and in particular to a leakage detection device, a water-cooled radiator, and a computer. Background Technology
[0002] Currently, some computers on the market use water-cooled radiators. Some of these water-cooled radiators, in addition to having sealing structures at the pipe joints to prevent leaks, also have leak detection devices. These devices apply a color-changing coating to areas prone to leaks, so when a leak occurs, a liquid of a certain color can be seen flowing out, allowing users to determine if a leak has occurred.
[0003] However, this solution has significant limitations. It requires the application of coatings to various leak-prone areas. Furthermore, the solution becomes ineffective if leaks occur in other areas, potentially leading to substantial losses for users due to their failure to detect leaks in a timely manner. Utility Model Content
[0004] The main purpose of this invention is to provide a leak detection device, a water-cooled radiator, and a computer, aiming to improve the comprehensiveness of the leak detection device.
[0005] To achieve the above objectives, the leakage detection device proposed in this utility model includes:
[0006] Mounting base, wherein the mounting base is provided with a negative pressure chamber, the negative pressure chamber being used to connect to the water channel to be tested;
[0007] A telescopic component is connected to the mounting base, and a telescopic cavity is formed inside the telescopic component, which is connected to the negative pressure cavity;
[0008] An elastic element, located within the telescopic cavity, with one end connected to the mounting base and the other end connected to the telescopic element; and
[0009] The detection element is installed on the mounting base and is positioned opposite to the telescopic component. When the telescopic component and the detection element are spaced apart, the detection element detects the telescopic component's extension or contraction to detect leakage in the water circuit under test. When the telescopic component contacts the detection element, the detection element detects the pressure exerted by the telescopic component on the detection element to detect leakage in the water circuit under test.
[0010] In one embodiment, the telescopic member includes a corrugated bladder, the telescopic cavity being formed within the corrugated bladder, and the opening of the telescopic cavity being sealed to the mounting base.
[0011] In one embodiment, the outer diameter of the corrugated bladder is set to decrease toward the detection element.
[0012] In one embodiment, the diameter of the negative pressure chamber is D1, and the maximum inner diameter of the corrugated bladder is D2, where D1 ≤ 1 / 2D2.
[0013] In one embodiment, a limiting post is provided on the wall of the negative pressure chamber, and the length direction of the limiting post is consistent with the extension and retraction direction of the telescopic member.
[0014] In one embodiment, the leakage detection device further includes a limiting rod, one end of which is fixed to the telescopic member. A limiting through hole is provided in the limiting post, the limiting through hole diffracts along the length direction of the limiting post and communicates with the negative pressure chamber, and the limiting rod is slidably connected in the limiting through hole.
[0015] In one embodiment, the elastic element includes a spring, which is sleeved on the outer periphery of the limiting post.
[0016] In one embodiment, the outer periphery of the limiting rod is provided with at least one flow channel, and the negative pressure cavity and the telescopic cavity are connected through the flow channel.
[0017] In one embodiment, the mounting base includes a base and a cover connected together, the telescopic member is sealed to the base, the negative pressure chamber is disposed on the base, and the detection member is connected to the end of the cover opposite to the base.
[0018] This utility model also proposes a water-cooled radiator, including the leakage detection device described above.
[0019] This utility model also proposes a computer, including the water-cooled radiator as described above.
[0020] The leakage detection device in this utility model includes a mounting base, a telescopic component, an elastic component, and a detection component. The telescopic cavity, the negative pressure cavity, and the water path to be tested are connected in sequence. Before the detection component detects, the negative pressure cavity and / or the water path to be tested are under negative pressure. The suction force of the negative pressure in the negative pressure cavity and / or the water path to be tested is balanced with the elastic force of the elastic component. At this time, the telescopic component remains in a balanced state, neither expanding nor contracting. However, if there is a leak in the water path to be tested, it indicates that the negative pressure cavity and the water path to be tested are connected to the external atmosphere. At this time, the suction force of the negative pressure cavity and / or the water path to be tested gradually decreases, and the elastic force of the elastic component gradually takes over, pushing the telescopic component to expand. When the expansion joint and the detection unit are spaced apart, the detection unit detects the expansion and contraction of the expansion joint to detect leakage in the corrugated water circuit under test. When the expansion joint and the detection unit are in contact, the detection unit detects the pressure exerted by the expansion joint on the detection unit to detect leakage in the corrugated water circuit under test. This allows for the detection of leaks in any part of the water circuit under test, enabling the leakage detection device to detect and provide timely feedback, achieving comprehensive detection. Furthermore, after resolving the leakage problem in the water-cooled circulation pipeline, the expansion joint is reset, and the pressure in the negative pressure chamber returns to its initial state, allowing the leakage detection device to be reused, thereby improving the comprehensiveness of the leakage detection device.

[0032] Reference Figures 1 to 3 This utility model proposes a leakage detection device 1, comprising:
[0033] Mounting base 10, wherein a negative pressure chamber 10a is provided inside the mounting base 10, and the negative pressure chamber 10a is used to connect to the water channel to be tested;
[0034] The telescopic component is connected to the mounting base 10, and a telescopic cavity 20a is formed inside the telescopic component, which is connected to the negative pressure cavity 10a.
[0035] An elastic element 30 is located within the telescopic cavity 20a, with one end connected to the mounting base 10 and the other end connected to the telescopic member; and
[0036] The detection element 40 is installed on the mounting base 10 and is disposed opposite to the telescopic member. When the telescopic member and the detection element 40 are spaced apart, the detection element 40 detects the telescopic member's extension and contraction to detect leakage in the water circuit to be tested. When the telescopic member contacts the detection element 40, the detection element 40 detects the pressure exerted by the telescopic member on the detection element 40 to detect leakage in the water circuit to be tested.
[0037] The leakage detection device 1 in this utility model includes a mounting base 10, a telescopic component, an elastic component 30, and a detection component 40. The telescopic cavity 20a, the negative pressure cavity 10a, and the water path to be detected are connected in sequence. Before the detection component 40 detects, the negative pressure cavity 10a and / or the water path to be detected are in a negative pressure state. The suction force of the negative pressure in the negative pressure cavity 10a and / or the water path to be detected is balanced with the elastic force of the elastic component 30. At this time, the telescopic component is in a balanced state. However, if there is a leak in the water path to be detected, it indicates that the negative pressure cavity 10a and the water path to be detected are connected to the external atmosphere. At this time, the suction force of the negative pressure cavity 10a and / or the water path to be detected gradually decreases, and the elastic force of the elastic component 30 gradually plays a dominant role, pushing the telescopic component... When the telescopic component extends and is spaced apart from the detection component 40, the detection component 40 detects the extension and contraction of the telescopic component to detect leakage in the water circuit under test in the bellows 20. When the telescopic component contacts the detection component 40, the detection component 40 detects the pressure exerted by the telescopic component on the detection component 40 to detect leakage in the water circuit under test in the bellows 20. This allows for the detection of leaks in the water circuit under test regardless of their location, enabling the leakage detection device 1 to detect and provide timely feedback, achieving comprehensive detection. Furthermore, after resolving the leakage problem in the water-cooled circulation pipeline, the telescopic component is reset, restoring the pressure in the negative pressure chamber 10a to its initial state, allowing the leakage detection device 1 to be reused, thereby improving the comprehensiveness of the leakage detection device 1. The reset of the telescopic component can be achieved by the user manually pressing the telescopic component to reset it, then drawing the negative pressure chamber 10a and / or the water circuit under test into a negative pressure, or by the telescopic component automatically resetting under the suction force of the negative pressure during the formation of negative pressure in the negative pressure chamber 10a and / or the water circuit under test.
[0038] Furthermore, the detection element 40 can be a displacement sensor to detect the amount of expansion and contraction of the telescopic member, or a pressure sensor to detect the pressure of the telescopic member on the detection element 40. Of course, the detection element 40 can also be equipped with both a displacement sensor and a pressure sensor.
[0039] Understandably, the detection component 40 can not only detect the expansion and contraction of the expansion component, but also judge the time taken for that expansion and contraction. If a large expansion and contraction is achieved in a short time, it indicates that the leakage point of the water circuit under test is large. The size of the leakage point of the water circuit under test can be judged by the expansion and contraction speed of the expansion component, thereby reminding the user to make the corresponding feedback in a timely manner.
[0040] It should be further explained that the negative pressure in the negative pressure chamber 10a and / or the water circuit under test can be achieved by suctioning the negative pressure chamber 10a and / or the water circuit under test into a negative pressure state after the leakage detection device 1 is sealed and connected to the water circuit under test. Alternatively, it can be that the liquid in the water circuit under test is driven to flow using a suction principle during the operation of the pump, thereby creating a negative pressure in the water circuit under test.
[0041] Specifically, the telescopic component includes a bellows 20, within which a telescopic cavity 20a is formed. The opening of the telescopic cavity 20a is sealed to the mounting base 10. The bellows 20 indicates that the telescopic component is corrugated, similar to a bellows pipe. The bellows 20 is integrally formed without any connecting gaps, thus providing good sealing. Furthermore, the corrugated design of the bellows 20 allows for significant elastic deformation in the axial direction, facilitating axial deformation and enabling the elastic element 30 to better push the telescopic component along the axial direction. This reduces the offset of the telescopic component in other directions, thereby improving the accuracy of the leakage detection device 1.
[0042] Furthermore, the outer diameter of the bellows 20 is reduced towards the detection element 40. Understandably, as the telescopic member moves towards the detection element 40, it inevitably shifts radially within the negative pressure chamber 10a due to its gradual expansion and contraction. Therefore, by reducing the outer diameter of the bellows 20 towards the detection element 40, the possibility of the bellows 20 contacting the wall of the negative pressure chamber 10a is reduced, thereby reducing the friction between the telescopic member and the wall of the negative pressure chamber 10a. This allows the pressure change within the negative pressure chamber 10a to have a greater effect on the axial expansion and contraction of the telescopic member, thus improving the accuracy and reliability of the leakage detection device 1.
[0043] Optionally, the diameter of the negative pressure chamber 10a is D1, and the maximum inner diameter of the corrugated bladder 20 is D2, where D1 ≤ 1 / 2D2. The maximum inner diameter of the corrugated bladder 20 is the straight-line distance between the two crests of the corrugated section, which is equivalent to the volume of the negative pressure chamber 10a. This allows the corrugated bladder 20 to respond quickly even if the leakage area of the water path to be detected is small, thereby improving the sensitivity of the corrugated bladder 20 and the leakage detection device 1.
[0044] During the process of drawing negative pressure into the negative pressure chamber 10a, in order to prevent the telescopic component from contracting in a direction away from the detection component 40, in one embodiment, a limiting post 111 is provided on the wall of the negative pressure chamber 10a. The length direction of the limiting post 111 is consistent with the telescopic component's extension and retraction direction. By setting the limiting post 111, the telescopic component is prevented from extending and retracting in the opposite direction away from the detection component 40, thereby improving the stability and reliability of the telescopic component during operation.
[0045] In one embodiment, the leakage detection device 1 further includes a limiting rod 21, one end of which is fixed to the telescopic member. A limiting through hole 112 is provided within the limiting post 111, the limiting through hole 112 diffracting along the length of the limiting post 111 and communicating with the negative pressure chamber 10a. The limiting rod 21 is slidably connected within the limiting through hole 112. By setting the limiting rod 21 and the limiting through hole 112 for limiting cooperation, the telescopic direction of the telescopic member is limited, thereby causing the telescopic member to telescopically extend and retract in a predetermined direction. Simultaneously, it reduces the non-axial force exerted on the telescopic member by the negative pressure suction of the negative pressure chamber 10a and / or the water path under test, and the elastic force of the elastic member 30, thereby reducing the possibility of contact between the telescopic member and the negative pressure chamber 10a, reducing the influence of friction, and improving the accuracy of the leakage detection device 1.
[0046] Specifically, the elastic element 30 includes a spring, which is sleeved on the outer periphery of the limiting post 111. The spring has a simple structure, is easy to install, has stable and reliable performance, and is low in cost, thereby reducing the manufacturing cost of the leakage detection device 1 and improving the stability of the leakage detection device 1.
[0047] Understandably, when the limiting rod 21 slides within the limiting through hole 112, in order to better limit the movement of the limiting rod 21, the diameter of the limiting through hole 112 is generally only slightly larger than that of the limiting rod 21. Since the negative pressure chamber 10a is connected to the telescopic chamber 20a through the limiting through hole 112, if the limiting rod 21 is set to a complete cylindrical shape, it will result in the airflow flowing in from the leak point having difficulty entering the telescopic chamber 20a due to the small distance between the limiting rod 21 and the wall of the limiting through hole 112 when a water leak is detected, thus making it difficult to push the telescopic component to extend. Simultaneously, due to the small distance between the limiting rod 21 and the wall of the limiting through hole 112, external airflow may also disturb the movement of the limiting rod 21, leading to… The limiting rod 21 is prone to offset and tilting, which increases the friction between the limiting rod 21 and the wall of the limiting through hole 112, increases the noise during operation, and reduces the accuracy and reliability of the leakage detection device 1. Therefore, in one embodiment, at least one flow channel 211 is provided on the outer periphery of the limiting rod 21. The negative pressure chamber 10a and the telescopic chamber 20a are connected through the flow channel 211, thereby increasing the flow diameter between the negative pressure chamber 10a and the telescopic chamber 20a, thereby reducing the influence of airflow on the movement of the limiting rod 21, and also allowing the airflow flowing in from the leak to quickly enter the telescopic chamber 20a, thereby enabling the telescopic component to react quickly and improving the sensitivity of the leakage detection device 1.
[0048] In one embodiment, the mounting base 10 includes a base 11 and a cover 12 connected together. The telescopic member is sealed to the base 11, the negative pressure chamber 10a is disposed on the base 11, and the detection element 40 is connected to the end of the cover 12 opposite to the base 11. By setting the mounting base 10 as a separate unit consisting of the base 11 and the cover 12, the connection between the telescopic member, the elastic member 30, and the detection element 40 is facilitated. It also facilitates the manufacturing of the negative pressure chamber 10a and the limiting post 111, thereby reducing the manufacturing cost of the leakage detection device 1. The corrugated bladder 20 is sandwiched between the base 11 and the cover 12, thus achieving a sealed connection between the base 11 and the cover 12. The base 11 and the cover 12 can be welded, bonded, or screwed together using mounting holes. Of course, in other embodiments, the base 11 and the cover 12 can also be integrally formed.
