Description

Technical Field

[0001] This application relates to the field of leakage detection technology, specifically to a detection line. Background Technology

[0002] Coolant leakage detection technology is crucial in liquid cooling systems, especially in high-density, high-reliability applications such as data centers, energy storage systems, and new energy vehicles. Its development is closely related to the popularization of liquid cooling technology.

[0003] The principle of leakage detection technology is to pre-place a detection resistor of about 1 megohm between the detection leads. Since the leakage liquid usually contains electrolyte ions and has a certain conductivity, when the leakage liquid seeps into the detection line area, the leakage liquid forms a conductive path in parallel with the above-mentioned resistor between the two leads. This is equivalent to the leakage liquid connecting the above-mentioned resistor in parallel, which significantly reduces the total resistance. The detection equipment can accurately identify the leakage phenomenon by monitoring the significant decrease in the circuit resistance in real time.

[0004] However, the existing testing line production process is relatively complex and costly.

[0005] It should be noted that the information in the background section above is only used to enhance the understanding of the background technology of this application, and therefore may include technical information that does not constitute technical information known or easily inferred by a person skilled in the art.

[0008] Furthermore, the insulating kit includes: a first insulating layer and a second insulating layer; The first conductor and the second conductor are disposed between the first insulating layer and the second insulating layer; Both the first insulating layer and the second insulating layer are provided with the through holes.

[0018] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0019] The inventors, through analysis of existing technologies, discovered that current leakage detection lines typically employ a structure where a braided mesh is wrapped around a copper conductor to allow liquid to penetrate and contact the copper wire, thereby triggering a detection signal. However, this braided mesh structure is time-consuming in the wire stripping process, consuming a large portion of the time in traditional manufacturing processes, and requires specialized fixtures, resulting in a complex overall production process, low efficiency, and increased manufacturing costs. Furthermore, existing detection lines require the soldering of a PCB board with integrated resistors to the conductor via four solder points, which also limits production efficiency.

[0020] It should be noted that, in any embodiment of this application, the leaked liquid may include various liquids that are accidentally leaked during equipment operation and have a certain degree of conductivity, such as coolant, electrolyte, aqueous solution containing ions, or partially conductive hydraulic oil.

[0021] Reference Figure 1-4This illustration shows a detection line provided in an embodiment of the present application, comprising: an insulating kit 1, a first conductor 21, a second conductor 22, and a detection resistor; The first conductor 21 and the second conductor 22 are arranged side by side, forming an electrically isolated slit channel 23 between them; the detection resistor is connected in series between the first conductor 21 and the second conductor 22; The insulating kit 1 covers the outside of the first conductor 21 and the second conductor 22; the insulating kit 1 has a plurality of through holes 13 corresponding to the slit channel 23; When the leaking liquid enters the slit channel 23 from the through hole 13, the first conductor 21 and the second conductor 22 form a conductive bridge through the leaking liquid.

[0022] In the embodiments of this application, considering the complex and costly production process of existing detection lines, this application provides a solution by setting through holes 13 corresponding to the slit channel 23 in the insulating kit 1 for leakage liquid to pass through. Specifically, this solution includes: an insulating kit 1, a first conductor 21, a second conductor 22, and a detection resistor; the first conductor 21 and the second conductor 22 are arranged side-by-side, forming an electrically isolated slit channel 23 between them; the detection resistor is connected in series between the first conductor 21 and the second conductor 22; the insulating kit 1 covers the outside of the first conductor 21 and the second conductor 22; the insulating kit 1 has several through holes 13 corresponding to the slit channel 23; when leakage liquid enters the slit channel 23 through the through holes 13, the first conductor 21 and the second conductor 22 form a conductive bridge through the leakage liquid; the width of the through holes 13 is greater than the width of the slit channel 23, so that the through holes 13 form a welding area on the surface of the first conductor 21 and the second conductor 22 for welding the detection resistor. This application simplifies the structure of the detection line and facilitates production by providing a through hole 13 corresponding to the slit channel 23 in the insulating kit 1, allowing leaked liquid to directly enter the slit channel 23 through the through hole 13.

[0023] The following will further describe a detection line in this exemplary embodiment.

[0024] It should be noted that the two ends of the detection resistor can be soldered to the first conductor 21 and the second conductor 22 (not shown in the figure) respectively through the through hole 13, requiring only 2 solder points, without the need for wire stripping and PCB soldering.

[0025] In one embodiment of this application, the through hole 13 has a square structure and is distributed in a linear array along the length of the slit channel 23.

[0026] It should be noted that the spacing between the through holes 13 can be set to less than 0.5 mm to improve the overall effective detection area of ​​the detection line.

[0027] In one specific implementation, the length of the through hole 13 along the length direction of the slit channel 23 is set to 1.2-1.4 mm; the length of the through hole 13 along the width direction of the slit channel 23 is set to 2.4-2.8 mm.

[0028] In one embodiment of this application, the insulating kit 1 includes: a first insulating layer 11 and a second insulating layer 12; The first conductor 21 and the second conductor 22 are disposed between the first insulating layer 11 and the second insulating layer 12; Both the first insulating layer 11 and the second insulating layer 12 are provided with the through hole 13.

[0029] It should be noted that by setting the through holes 13 on both sides of the first conductor 21 and the second conductor 22 respectively, the overall effective detection area of ​​the detection line can be increased compared with setting it on one side.

[0030] In one embodiment of this application, the through holes 13 of the first insulating layer 11 and the through holes 13 of the second insulating layer 12 are asymmetrically distributed.

[0031] It should be noted that the asymmetrically distributed through holes 13 can further increase the overall effective detection area of ​​the detection line.

[0032] In one embodiment of this application, the first insulating layer 11 and the second insulating layer 12 are PET insulating films.

[0033] It should be noted that PET insulating film (Polyethylene Terephthalate Insulation Film) is a high-performance insulating material based on polyester. It has excellent mechanical strength, heat resistance, electrical insulation and chemical stability. It is widely used in wires and cables, electronic components, motor windings and flexible circuit boards as interlayer insulation, conductor covering or protective isolation layer.

[0034] In one embodiment of this application, the first conductor 21 and the second conductor 22 are copper foils.

[0035] It should be noted that compared to ordinary copper wire, copper foil has higher bending resistance, thereby improving the applicability of the testing line in different environments.

[0036] As an example, the first conductor 21 and the second conductor 22 may also be highly conductive materials such as silver foil.

[0037] In one embodiment of this application, the first conductor 21 and the second conductor 22 are flat and elongated structures, and the slit channel 23 is formed on the narrower side of both.

[0038] It should be noted that the flat, elongated conductor can increase the leakage receiving area, allowing the leaked liquid to enter the slit channel 23 more quickly when a liquid leak occurs, thus enabling detection.

[0039] In one embodiment of this application, the width of the first conductor 21 and the second conductor 22 is set to 1.4-1.6 mm; the thickness of the first conductor 21 and the second conductor 22 is set to 0.2-0.4 mm.

[0040] It should be noted that the first conductor 21 and the second conductor 22 are set with appropriate widths to facilitate the welding of the detection resistor, and the lower thickness is set to reduce the overall volume of the detection line.

[0041] In one embodiment of this application, the width of the slit channel 23 is set to 0.1-0.3 mm.

[0042] It should be noted that when liquid leakage occurs, appropriately reducing the width of the slit channel 23 can allow the leaked liquid to penetrate the slit channel 23 more fully, thereby improving the response time and accuracy of detection, and also enabling the detection of smaller liquid droplets.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present application.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or terminal device.
