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 sliding cavity;
[0007] A movable component slides within the sliding cavity and is sealed to the mounting base, thereby dividing the sliding cavity into a first cavity and a second cavity, wherein the first cavity is used to connect to the water path to be tested.
[0008] An elastic element, located between the mounting base and the movable member, is elastically connected to the mounting base; and
[0009] The detection element is installed on the mounting base and located at the opening of the second cavity. When the movable element and the detection element are spaced apart, the detection element detects the displacement of the movable element to detect the leakage of the water circuit to be tested. When the movable element contacts the detection element, the detection element detects the pressure of the movable element on the detection element to detect the leakage of the water circuit to be tested.
[0010] In one embodiment, the movable element includes a piston that is slidably and sealingly connected to a sliding cavity.
[0011] In one embodiment, the movable component includes a limiting rod connected to the piston, and the elastic component includes a spring. The two ends of the spring are respectively connected to the mounting base and the side of the piston away from the second cavity. The spring is sleeved on the outer periphery of the limiting rod. The first cavity includes a movable section, a limiting section, and a negative pressure section connected in sequence. The limiting rod is limited to the limiting section, and the negative pressure section is used to connect with the water circuit to be tested.
[0012] In one embodiment, the spring is a tower spring.
[0013] In one embodiment, the leakage detection device further includes a first sealing ring, and the outer peripheral surface of the piston is provided with an annular first limiting groove. The first sealing ring is located within the first limiting groove so that the piston is sealed and connected to the sliding cavity.
[0014] In one embodiment, multiple first limiting grooves are provided at intervals, and one first limiting groove corresponds to one first sealing ring.
[0015] In one embodiment, the mounting base includes a base and a cover, the cover being sealed to the base, a second cavity being disposed in the cover, and a first cavity extending from the cover to the base.
[0016] In one embodiment, the leakage detection device further includes a second sealing ring sandwiched between the base and the cover.
[0017] This utility model also proposes a water-cooled radiator, including the leakage detection device described above.
[0018] This utility model also proposes a computer, including the water-cooled radiator as described above.
[0019] The leakage detection device of this utility model includes a mounting base, a movable component, an elastic component, and a detection component. The first cavity is connected to the water path to be detected. When the detection component is not detecting, the first cavity and / or the water path to be detected are under negative pressure. The suction force of the negative pressure in the first cavity and / or the water path to be detected is balanced with the elastic force of the elastic component, and the movable component is stationary. However, if there is a leak in the water path to be detected, the suction force of the negative pressure in the first cavity and / or the water path to be detected gradually decreases. At this time, the elastic force of the elastic component pushes the movable component to move closer to the detection component. When the movable component and the detection component are separated... During setup, the detection element measures the displacement of the moving part to detect leaks in the water circuit under test. When the moving part contacts the detection element, the detection element measures the pressure exerted by the moving part on the detection element to detect leaks in the water circuit under test. This allows for the detection of leaks regardless of their location in the water circuit under test, enabling the leak detection device to detect leaks and provide timely feedback, achieving comprehensive detection. Furthermore, after resolving the leak in the water-cooled circulation pipe, the moving part is reset, restoring the pressure in the first chamber to its initial state, allowing the leak detection device to be reused, thereby improving the comprehensiveness of the leak detection device.

[0031] Reference Figures 1 to 3 This utility model proposes a leakage detection device 1, comprising:
[0032] Mounting base 10, wherein a sliding cavity 11 is provided inside the mounting base 10;
[0033] A movable component slides within the sliding cavity 11 and is sealed to the mounting base 10, thereby dividing the sliding cavity 11 into a first cavity 111 and a second cavity 112. The first cavity 111 is used to connect to the water path to be tested.
[0034] Elastic member 30, located between the mounting base 10 and the movable member, such that the elastic member 30 is elastically connected to the mounting base 10; and
[0035] The detection element 40 is installed on the mounting base 10 and located at the opening of the second cavity 112. When the movable part and the detection element 40 are spaced apart, the detection element 40 detects the displacement of the movable part to detect the leakage of the water circuit to be tested. When the movable part is in contact with the detection element 40, the detection element 40 detects the pressure of the movable part on the detection element 40 to detect the leakage of the water circuit to be tested.
[0036] The leakage detection device 1 of this utility model includes a mounting base 10, a movable component, an elastic component 30, and a detection component 40. The first cavity 111 is connected to the water path to be detected. When the detection component 40 is not detecting, the first cavity 111 and / or the water path to be detected are under negative pressure. The suction force of the negative pressure in the first cavity 111 and / or the water path to be detected is balanced with the elastic force of the elastic component 30. At this time, the movable component is stationary. However, if there is a leak in the water path to be detected, the suction force of the negative pressure in the first cavity 111 and / or the water path to be detected gradually decreases. At this time, the elastic force of the elastic component 30 pushes the movable component to move closer to the detection component 40. When the detection element 40 is spaced apart from the moving part, it detects the displacement of the moving part to detect leakage in the water circuit under test. When the moving part contacts the detection element 40, it detects the pressure exerted by the moving part on the detection element 40 to detect leakage in the water circuit under test. This allows leakage to be detected regardless of where it occurs in the water circuit under test, and the leakage detection device 1 can detect and provide timely feedback, achieving comprehensive detection. Furthermore, after resolving the leakage problem in the water-cooled circulation pipe, the moving part is reset, and the pressure inside the first cavity 111 returns to its initial state, allowing the leakage detection device 1 to be reused, thereby improving the comprehensiveness of the leakage detection device 1. The detection element 40 can be a displacement sensor, a pressure sensor, or both.
[0037] The resetting of the movable part can be achieved by the user manually pressing the movable part to reset it, and then drawing the first cavity 111 and / or the water path to be tested into a negative pressure, or it can be achieved by the user automatically resetting it under the action of negative pressure suction during the process of forming a negative pressure in the first cavity 111 and / or the water path to be tested.
[0038] Understandably, the detection component 40 can not only detect the displacement of the moving part, but also judge the time taken for that displacement. If a large displacement is reached in a short time, it indicates that the leakage point of the water circuit to be tested is large. The size of the leakage point of the water circuit to be tested can be judged by the moving speed of the moving part, thereby reminding the user to make the corresponding feedback in a timely manner.
[0039] It should be further explained that the negative pressure in the first chamber 111 and / or the water circuit to be tested can be achieved by suctioning the first chamber 111 and / or the water circuit to be tested into a negative pressure state after the leakage detection device 1 is sealed and connected to the water circuit to be tested. Alternatively, it can be that the liquid in the water circuit to be tested is driven to flow using a suction principle during the operation of the pump, thereby creating a negative pressure in the water circuit to be tested.
[0040] Specifically, the movable component includes a piston 20, which is slidably and sealingly connected to the sliding cavity 11. When the water path to be tested is not leaking, the piston 20 maintains a balanced state under the action of the negative pressure suction in the first cavity 111 and / or the water path to be tested and the elastic force of the elastic element 30. When a leak occurs at any position in the water path to be tested, the water path to be tested and the first cavity 111 are essentially connected to the external atmosphere. At this time, the negative pressure suction in the first cavity 111 and / or the water path to be tested gradually decreases, thereby allowing the elastic element 30 to play a leading role in pushing the piston 20 to move towards the detection element 40.
[0041] Furthermore, the movable component includes a limiting rod 21 connected to the piston 20, and the elastic component 30 includes a spring. The two ends of the spring are respectively connected to the mounting base 10 and the side of the piston 20 away from the second cavity 112. The spring is sleeved on the outer periphery of the limiting rod 21. The first cavity 111 includes a movable section 111c, a limiting section 111b, and a negative pressure section 111a connected in sequence. The limiting rod 21 is limited to the limiting section 111b, and the negative pressure section 111a is used to connect with the water channel to be tested. By setting the limiting rod 21 and the limiting segment 111b to limit the movement direction of the piston 20, the piston 20 is limited, thereby allowing the piston 20 to slide in the predetermined direction. At the same time, the forces exerted on the piston 20 in other directions by the negative pressure suction of the first cavity 111 and / or the water path to be tested and the elastic force of the elastic element 30 are reduced, thereby reducing the friction between the piston 20 and the cavity wall of the sliding cavity 11. This reduces the influence of friction and prevents the piston 20 from failing to move when the water path to be tested leaks due to excessive friction between the piston 20 and the wall of the sliding cavity 11. This improves the accuracy of the leak detection device 1.
[0042] Understandably, when the limiting rod 21 slides within the limiting section 111b, in order to better limit the movement of the limiting rod 21, the diameter of the limiting section 111b is generally only slightly larger than that of the limiting rod 21. The movable section 111c is connected to the negative pressure section 111a through the limiting section 111b. Therefore, if the limiting rod 21 is set as a complete cylinder, when a leak is detected in the water circuit, the distance between the limiting rod 21 and the wall of the limiting section 111b will be too small, making it difficult for the airflow flowing in from the leak to enter the telescopic cavity, thus making it difficult to push the piston 20 to move. Simultaneously, because the distance between the limiting rod 21 and the wall of the limiting section 111b is too small, external airflow may also disturb the movement of the limiting rod 21, further hindering its movement. 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 section 111b, 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 movable section 111c and the negative pressure section 111a are connected through the flow channel 211, thereby increasing the flow diameter between the movable section 111c and the negative pressure section 111a, 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 negative pressure section 111a, thereby enabling the movable part to react quickly and improving the sensitivity of the leakage detection device 1.
[0043] Optionally, in one embodiment, the diameter of the limiting segment 111b and / or the negative pressure segment 111a is at most half the diameter of the moving segment 111c. Understandably, setting the diameters of the limiting segment 111b and the negative pressure segment 111a to less than or equal to half the diameter of the moving segment 111c effectively reduces the cavity volume within the limiting segment 111b and the negative pressure segment 111a. This allows the piston 20 to respond quickly even if the leakage area of the water path to be detected is small, thereby improving the sensitivity of the piston 20 and the leakage detection device 1.
[0044] Preferably, the spring is a tower spring. When a tower spring is compressed, its smaller end coil is more likely to deform and enter the inner diameter space of the adjacent larger coil. This characteristic makes the spring tend to remain in the center position during compression, greatly reducing the bending instability or lateral displacement problems that are prone to occur in ordinary cylindrical springs with a large length-to-diameter ratio. This allows the piston 20 to maintain precise linear movement, thereby reducing friction and noise, improving guiding accuracy, and further improving the accuracy of the leakage detection device 1.
[0045] In one embodiment, the leakage detection device 1 further includes a first sealing ring 23. The outer circumferential surface of the piston 20 is provided with an annular first limiting groove 22. The first sealing ring 23 is confined within the first limiting groove 22, so that the piston 20 is sealed and connected within the sliding cavity 11. By providing the first sealing ring 23, the sealing performance between the piston 20 and the wall of the sliding cavity 11 is improved, thereby preventing external airflow from entering the first cavity 111, and thus improving the accuracy and reliability of the leakage detection device 1. The first limiting groove 22 ensures that when the piston 20 slides within the sliding cavity 11, the first sealing ring 23 always maintains its installed position, thereby reducing the possibility of the first sealing ring 23 shifting.
[0046] Furthermore, multiple first limiting grooves 22 are provided at intervals, with each first limiting groove 22 corresponding to one first sealing ring 23. By providing multiple first sealing rings 23 at intervals, the sealing performance between the piston 20 and the sliding cavity 11 is improved.
[0047] In one embodiment, the mounting base 10 includes a base 12 and a cover 13, the cover 13 being sealed to the base 12, the second cavity 112 being disposed on the cover 13, and the first cavity 111 extending from the cover 13 to the base 12. By configuring the mounting base 10 as a separate unit consisting of a base 12 and a cover 13, the connection between the piston 20, the elastic element 30, and the detection element 40 is facilitated. This also facilitates the manufacturing and processing of the first cavity 111 and the second cavity 112, thereby reducing the manufacturing cost of the leakage detection device 1.
[0048] Specifically, the leakage detection device 1 further includes a second sealing ring 14, which is sandwiched between the base 12 and the cover 13. By providing the second sealing ring 14, the sealing performance between the base 12 and the cover 13 is improved, thereby reducing the possibility of leakage between the base 12 and the cover 13, and thus improving the reliability and stability of the leakage detection device 1. Of course, in other embodiments, the base 12 and the cover 13 can also be integrally formed.
[0049] Reference Figure 4 The present invention also proposes a water-cooled radiator 2, which includes a leakage detection device 1.
