Description

A liquid leakage detection tape

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on January 19, 2024, with application number 202420144197.5 and application name “A Liquid Leakage Detection Belt”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present application relates to the technical field of liquid cooling devices, and in particular to a liquid leakage detection belt. Background Art

[0003] The server generates a lot of heat during operation. In order to ensure the normal operation of the server, a cooling device is needed to dissipate the heat from the server. The cooling devices mainly include air cooling devices and liquid cooling devices. Liquid cooling devices are widely used due to their advantages such as fast heat dissipation, low noise, low energy consumption and good environmental adaptability.

[0004] Since the liquid cooling device may leak during operation, if the leaked liquid comes into contact with electronic components on the server, it may damage the electronic components or even the entire server, resulting in serious consequences such as data loss.

[0005] At present, a liquid leakage detection tape is mainly used for liquid leakage detection. A connector is provided at each end of the liquid leakage detection tape. When in use, one of the connectors is connected to the liquid leakage detector. At this time, since the other connector is far away from the liquid leakage detector, an additional wire is needed to connect the connector far away from the liquid leakage detector to the liquid leakage detector, or the liquid leakage detection tape is bent so that the two connectors are on the same side. As a result, the connection of the liquid leakage detection tape is relatively messy. Therefore, due to its structure, the existing liquid leakage detection tape is inconvenient to disconnect and connect, and it is inconvenient to maintain.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] Please refer to Figure 1. A leakage detection belt provided in an embodiment of the present application includes a base belt 10, a first leakage detection wire 20 and a second leakage detection wire 30. The first leakage detection wire 20 and the second leakage detection wire 30 are distributed at intervals on the base belt 10, wherein the base belt 10 can be optionally a flexible belt. When the leakage detection belt is used for leakage detection of an infusion pipeline, a protective tube can be provided outside the infusion pipeline, and the leakage detection belt can be attached to the inner wall of the protective tube. The leakage detection belt can be arranged in a manner parallel to the axial direction of the protective tube, or can be spirally distributed on the inner wall of the protective tube along the axial direction of the protective tube. Therefore, the base belt 10 is set as a flexible belt to facilitate the distribution of the leakage detection belt in the protective tube; when the liquid cooling device adopts a water collection tank to collect leakage, a flexible belt can be laid on the inner bottom surface of the water collection tank, and the leakage detection belt can be distributed in the water collection tank in an S shape. The first leakage detection wire 20 and the second leakage detection wire 30 can be formed on the base tape 10 by electroplating. The shape of the base tape 10 can be selected as a long strip. The first leakage detection wire 20 and the second leakage detection wire 30 can be in the shape of a straight line, a broken line or a wavy line, as long as the first leakage detection wire 20 and the second leakage detection wire 30 are arranged at intervals. Among them, the first leakage detection wire 20 and the second leakage detection wire 30 extend from the first end of the baseband 10 to the second end of the baseband 10, and wrap around to the first end of the baseband 10. The first end and the second end of the baseband 10 are the two ends of the baseband 10 that are far away from each other in its length direction, that is, the two ends of the first leakage detection wire 20 and the second leakage detection wire 30 are located at the same end of the baseband 10. Therefore, when connecting the leakage detection belt to the leakage detector, there is no need to bend the two ends of the leakage detection belt to the same end, nor is there any need to use an additional wire to lead the end of the leakage detection belt away from the leakage detector to the leakage detector. Therefore, the convenience of disassembly and connection of the leakage detection belt can be effectively improved, and the clutter of the wiring of the leakage detection belt can be reduced, thereby improving the convenience of maintenance.

[0028] In some embodiments, the first end of the baseband 10 is provided with a first extension 11 and a second extension 12. As shown in FIG1 , the left end of the baseband 10 is provided with the first and second extensions 11, 12 extending leftward. The widths of the first and second extensions 11, 12 are smaller than the width of the baseband 10 itself. The first and second extensions 11, 12 can be arranged parallel to each other or non-parallel to each other. The first terminals 60 of the first and second leakage detection wires 20, 30 are located on the first extension 11, while the second terminals 70 of the first and second leakage detection wires 20, 30 are located on the second extension 12. The provision of the first and second extensions 11, 12 enhances the flexibility of the first and second terminals 60, 70. For example, if the distance between the two interfaces corresponding to the first and second terminals 60, 70 on the leakage detector is greater or less than the distance between the first and second terminals 60, 70, the first and / or second extensions 11, 12 can be bent relative to the baseband 10 to accommodate the interfaces on the leakage detector. In order to facilitate bending of the first extension portion 11 and the second extension portion 12, an arc transition is adopted at the intersection of the first extension portion 11, the second extension portion 12 and the base band 10. As shown in FIG1 , an arc transition is adopted at the right angle between the right end of the first extension portion 11 and the left end of the base band 10, and an arc transition is adopted at the right angle between the right end of the second extension portion 12 and the left end of the base band 10.

[0029] In some embodiments, after the first leakage detection wire 20 extends from the first end to the second end of the baseband 10, it can be bent toward the second leakage detection wire 30, and then bent toward the first end of the baseband 10; after the second leakage detection wire 30 extends from the first end to the second end of the baseband 10, it can be bent in a direction away from the first leakage detection wire 20, and then bent toward the first end of the baseband 10. The layout after bending is shown in Figure 1. This layout is suitable for a structure in which the leakage detection belt has a first terminal 60 and a second terminal 70. In addition, after the first leakage detection wire 20 extends from the first end to the second end of the baseband 10, it can be bent in a direction away from the second leakage detection wire 30, and then bend toward the first end of the baseband 10; after the second leakage detection wire 30 extends from the first end to the second end of the baseband 10, it can be bent in a direction away from the first leakage detection wire 20, and then bend toward the first end of the baseband 10, that is, the first leakage detection wire 20 and the second leakage detection wire 30 are bent 180° at the second end, wherein the two ends of the first leakage detection wire 20 and the second leakage detection wire 30 are combined into one to form a connector 80. The layout after bending is shown in Figures 2 and 3. The first end of the baseband 10 is provided with an extension end 13, and the connector 80 is arranged on the extension end 13.

[0030] In some embodiments, at least one first detection piece 21 is provided on the side of the first leakage detection wire 20 facing the second leakage detection wire 30, and / or at least one second detection piece 31 is provided on the side of the second leakage detection wire 30 facing the first leakage detection wire 20. The detection pieces of the leakage detection strip can be distributed in three ways: the first detection piece 21 is provided on one side of the first leakage detection wire 20; the second detection piece 31 is provided on one side of the second leakage detection wire 30; and the third detection piece 21 is provided on one side of the first leakage detection wire 20 and the second detection piece 31 is provided on one side of the second leakage detection wire 30. In this arrangement, the first detection piece 21 and the second detection piece 31 do not contact each other; the first detection piece 21 and the second leakage detection wire 30 do not contact each other; and the second detection piece 31 and the first leakage detection wire 20 do not contact each other. During detection, when the leaked liquid contacts the first detection piece 21 and the second detection piece 31 at the same time, or contacts the first detection piece 21 and the second leakage detection wire 30 at the same time, or contacts the second detection piece 31 and the first leakage detection wire 20 at the same time, or contacts the first leakage detection wire 20 and the second leakage detection wire 30 at the same time, a leakage problem can be detected. Therefore, compared with the existing method of performing leakage detection only through the first leakage detection wire 20 and the second leakage detection wire 30, the leakage detection accuracy can be effectively improved.

[0031] In some embodiments, the first detection piece 21 and the second detection piece 31 are staggered and arranged at a preset distance. As shown in FIG1 , the first detection piece 21 and the second detection piece 31 are arranged in a comb-like shape, and the width of the first detection piece 21 and the second detection piece 31 can be greater than, less than, or equal to half the distance between the first leakage detection wire 20 and the second leakage detection wire. It should be noted that the first detection piece 21 and the second detection piece 31 shown in FIG1 , FIG2 and FIG3 are rectangular structures. In addition, they can also be other shapes such as triangles, trapezoids, L-shaped or T-shaped. As long as the first detection piece 21 is a structure that protrudes toward the second leakage detection wire 30, and the second detection piece 31 is a structure that protrudes toward the first leakage detection wire 20, it is sufficient.

[0032] In some embodiments, as shown in FIG1 , the baseband 10 is further provided with a first disconnection detection wire 40 and a second disconnection detection wire 50. The first disconnection detection wire 40 is located on the side of the first leakage detection wire 20 away from the second leakage detection wire 30, and the second disconnection detection wire 50 is located on the side of the second leakage detection wire 30 away from the first leakage detection wire 20. The first disconnection detection wire 40 and the second disconnection detection wire 50 extend from the first end of the baseband 10 to the second end of the baseband 10 and then wrap back to the first end of the baseband 10. The first disconnection detection wire 40 is used to detect whether the first leakage detection wire 20 is disconnected, and the second disconnection detection wire 50 is used to detect whether the second leakage detection wire 30 is disconnected, so that timely maintenance can be performed in the event of disconnection, thereby effectively improving the detection accuracy of the leakage detection tape.

[0033] In some embodiments, as shown in Figure 3, the first liquid leakage detection wire 20 is provided with a first contact 22, and the second liquid leakage detection wire 30 is provided with a second contact 32. The first contact 22 and the second contact 32 extend toward each other and are separated by a predetermined distance. When leaking liquid contacts the first contact 22 and the second contact 32 simultaneously, the leak detection function can also be performed. The base tape 10, the first liquid leakage detection wire 20, and the second liquid leakage detection wire 30 can be cut along the body of the first contact 22 and the second contact 32. Multiple sets of first contact 22 and second contact 32 can be provided along the length of the liquid leakage detection tape. When the length of the leakage detection tape is long, the leakage detection tape can be cut along the main body of the first connecting piece 22 and the second connecting piece 32. When the length of the leakage detection tape is short, a longer leakage detection tape can be connected at the cutoff point to meet the requirements of leakage detection of different lengths. Therefore, the adaptability of the leakage detection tape can be effectively improved, and there is no need to customize the leakage detection tape of the corresponding length according to the leakage detection length requirement. For example, when it is necessary to detect leakage of the infusion pipeline of the liquid cooling device, the existing leakage detection tape needs to be customized according to the length of the infusion pipeline. However, the cuttable leakage detection tape provided by the present application can be cut off or continued according to the length of the infusion pipeline, thereby reducing the customization cost.

[0034] In some embodiments, to facilitate cutting of the leakage detection tape, a cutting mark is provided on the base tape 10. The cutting mark can be an indentation provided on the leakage detection tape, or a colored line that is easily identifiable. As shown in FIG3 , the cutting mark passes through the main body of the first contact piece 22 and the second contact piece 32. When in use, the user can cut or break the leakage detection tape along the cutting mark as needed. This can avoid the problem of cutting off the tape, and also makes it easier for the user to find the cutting position, thereby improving cutting efficiency.

[0035] In some embodiments, the first contact 22 includes two first tapping pieces spaced apart along the length of the first leakage detection wire 20, and the two first tapping pieces are preferably of the same size. The second contact 32 includes two second tapping pieces spaced apart along the length of the second leakage detection wire 30, and the two second tapping pieces are preferably of the same size. The base tape 10, the first leakage detection wire 20, and the second leakage detection wire 30 can be cut between the two first tapping pieces and between the two second tapping pieces. By separating the first contact 22 and the second contact 32, it is possible to avoid the problem of the first leakage detection contact and the second leakage detection contact on one section having a smaller area and the first leakage detection contact and the second leakage detection contact on another section having a larger area after the leakage detection tape is cut.

[0036] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0037] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
