[0030] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 creative efforts are within the scope of protection of the present invention.

[0031] Please refer to Figure 1 , Figure 1 The present invention is a structural diagram of a liquid leakage detection sensor provided in a specific embodiment of the present invention.

[0032] The embodiment of the present invention provides a liquid leakage detection sensor, comprising: a first liquid leakage detection part 10 and a second liquid leakage detection part 20, wherein the first liquid leakage detection part 10 and the second liquid leakage detection part 20 are integrally constructed, wherein the first liquid leakage detection part 10 and the second liquid leakage detection part 20 generally both include a first liquid leakage detection wire and a second liquid leakage detection wire. When liquid leakage from the liquid cooling device contacts both the first liquid leakage detection wire and the second liquid leakage detection wire, the first liquid leakage detection wire and the second liquid leakage detection wire are short-circuited, and this indicates that the liquid cooling device is leaking. In specific use, the first liquid leakage detection part 10 is set at the first liquid leakage detection position of the liquid cooling device to detect liquid leakage at the first liquid leakage detection position, and the second liquid leakage detection part 20 is set at the second liquid leakage detection position of the liquid cooling device to detect liquid leakage at the second liquid leakage detection position. The first liquid leakage detection position and the second liquid leakage detection position are different liquid leakage detection positions on the liquid cooling device. Since the first leakage detection part 10 and the second leakage detection part 20 provided in the present application are an integrated structure, the two do not need to be connected through a plug connector. Therefore, compared with the method of connecting through a plug connector, the difficulty of installation can be effectively reduced. Especially for occasions where there are many leakage detection positions in the liquid cooling device, the labor intensity of the installer can be significantly reduced, and there is no need to consider the problem of disconnection of the plug connector or other false leakage alarms, so the leakage detection effect can be effectively improved.

[0033] It should be noted that the above embodiment uses only two leakage detection units as an example. In specific products, more leakage detection units can be provided, and multiple leakage detection units can be integrally constructed into a single leakage detection sensor. These units do not need to be connected using butt plug connectors or other connection methods. Furthermore, a leakage detection sensor can allow for some leakage detection units to be connected using butt plug connectors, but not all leakage detection units can be connected using butt plug connectors.

[0034] In some embodiments, the first leakage detection part 10 and / or the second leakage detection part 20 is provided with a connection end 121 for connecting to other leakage detection sensors or leakage collectors, that is, the first leakage detection part 10 and the second leakage detection part 20 share a connection end 121, wherein the connection end 121 can be optionally a gold finger end. For a liquid cooling device with more detection positions, a connection end 121 can be provided on the first leakage detection part 10 and the second leakage detection part 20 respectively. The leakage detection sensor of this structure can be connected to a leakage detection sensor of the same structure through one of the connection ends 121 through a plug-in connector, or can be connected to other conventional leakage detection sensors through a plug-in connector, and the other connection end 121 is connected to the leakage collector through a plug-in connector. For example Figure 1As shown, a connecting end 121 is provided at one end of the first liquid leakage detection part 10 away from the second liquid leakage detection part 20, and a reinforcing plate is provided at the connecting end 121 or the connecting end 121 is thickened, that is, the thickness of the connecting end 121 is greater than the thickness of the first liquid leakage detection part 10, thereby achieving the purpose of improving the structural strength of the connecting end 121.

[0035] In some embodiments, the liquid cooling device includes a delivery pipe and a liquid cooling plate, wherein the liquid cooling plate has a chamber disposed therein, and the delivery pipe is connected to the chamber within the liquid cooling plate. The liquid cooling plate can dissipate heat from heat-generating components on the server, such as a processor. A liquid collecting tank can be disposed on the liquid cooling plate, and leaked liquid within the liquid cooling plate can flow into the collecting tank. The first leakage detection portion 10 of the leakage detection sensor is a leakage detection strip, which is used to detect leakage in the delivery pipe of the liquid cooling device; the second leakage detection portion 20 is a leakage detection sheet, which is used to detect leakage in the liquid cooling plate of the liquid cooling device. The leakage detection strip and the leakage detection sheet are integrally constructed. Specifically, the first leakage detection wire of the leakage detection strip and the first leakage detection wire of the leakage detection sheet are the same wire, and the second leakage detection wire of the leakage detection strip and the second leakage detection wire of the leakage detection sheet are the same wire.

[0036] It should be noted that the leakage detection strip also includes a strip-shaped substrate for arranging the first and second leakage detection wires. The first and second leakage detection wires arranged on the strip-shaped substrate extend along the length of the strip-shaped substrate. The leakage detection sheet also includes a sheet-shaped substrate for arranging the first and second leakage detection wires. For a rectangular leakage detection sheet, the first leakage detection wire is arranged along one set of two adjacent edges, and the second leakage detection wire is arranged along another set of two adjacent edges. The first leakage detection branch line can be arranged on the side of the first leakage detection wire, and the second leakage detection branch line can be arranged on the side of the second leakage detection wire. The first and second leakage detection branch lines are arranged within the area enclosed by the first and second leakage detection wires. The number of first and second leakage detection branch lines can be selected based on the area of ​​the sheet-shaped substrate. The larger the area of ​​the sheet-shaped substrate, the greater the number of first and second leakage detection branch lines. If leaking liquid simultaneously contacts the first leakage detection wire and the second leakage detection branch wire, or the second leakage detection wire and the first leakage detection branch wire, or the first leakage detection branch wire and the second leakage detection branch wire, the leakage detection sensor will short-circuit. The strip-shaped substrate and the sheet-shaped substrate are integrally constructed, meaning there is no connector connecting them. During use, the leakage detection strip and sheet can simply be placed at the corresponding detection locations, eliminating the need for a plug-in connector to connect them. This significantly reduces the workload of the installer.

[0037] In some embodiments, the liquid leakage detection sensor further includes a third liquid leakage detection unit 30. The first liquid leakage detection unit 10, the second liquid leakage detection unit 20, and the third liquid leakage detection unit 30 are sequentially distributed and integrally constructed. For a liquid cooling device having two delivery pipes and a liquid cooling plate, one delivery pipe is connected to the liquid inlet of the liquid cooling plate, and the liquid outlet of the liquid cooling plate is connected to the other delivery pipe. In this case, the third liquid leakage detection unit 30 serves as a liquid leakage detection belt.

[0038] It should be noted that the above embodiment provides that the first and third liquid leakage detection units 10 and 30 are liquid leakage detection tapes, and the second liquid leakage detection unit 20 is a liquid leakage detection sheet. This is merely an example of a specific liquid cooling device structure. For liquid cooling devices with other structures, corresponding liquid leakage detection sensors may be selected. For example, the first, second, and third liquid leakage detection units 10, 20, and 30 may all be liquid leakage detection tapes; or all may be liquid leakage detection sheets; or at least some may be liquid leakage detection tapes, and the rest may be liquid leakage detection sheets; or at least one of the first, second, and third liquid leakage detection units 10, 20, and 30 may be a combination of a liquid leakage detection tape and a liquid leakage detection sheet. The distribution of the liquid leakage detection tapes and the liquid leakage detection sheets may be selected based on the specific liquid cooling device.

[0039] In some embodiments, as Figure 1As shown, the first liquid leakage detector 10 includes a first detection body, a first extension 11, and a connector extension 12. The outer tube is sheathed around the delivery pipe. When the first liquid leakage detector 10 is a liquid leakage detection strip, the first detection body is a strip-shaped structure. The first detection body is disposed on the inner wall of the outer tube, specifically, it can be adhered to the inner wall of the outer tube. The first detection body extends along the axial direction of the outer tube. The first extension 11 is located at a side end of the first detection body, the connector extension 12 is located at a side end of the first detection body, and the connecting end 121 is located on the side end of the connector extension 12 away from the first detection body. The second liquid leakage detector 20 includes a second detection body and a second extension 21. The second extension 21 is located at a side end of the first detection body and is integrally constructed with the first extension 11. To improve the structural strength of the liquid leakage detection sensor, a reinforcing plate can be provided on the surfaces of the first extension 11, the second extension 21, and the connector extension 12, or the first extension 11, the second extension 21, and the connector extension 12 can be thickened to prevent the extensions from being torn. When the second liquid leakage detection part 20 is a liquid leakage detection sheet, the second detection body is a sheet-like structure, and the liquid leakage detection sheet can cover the surface to be detected at the second liquid leakage detection position, for example, it can be attached to the inner bottom surface of the water collection tank. In order to avoid the liquid inlet joint, liquid outlet joint and liquid extraction port on the water collection tank, a liquid inlet avoidance gap, a liquid outlet avoidance gap and a liquid extraction avoidance gap can be provided on the liquid leakage detection sheet, wherein the leaked liquid in the water collection tank will flow to the liquid extraction port, and the water extraction pipe is located above the liquid extraction port. The leaked liquid in the water collection tank can be extracted through the water extraction pipe to prevent the leaked liquid stored in the water collection tank from overflowing and affecting the normal operation of the heating device, or even causing irreversible damage to the heating device.

[0040] In some embodiments, a first leakage detection wire and a second leakage detection wire of a first detection body are spaced apart, and a first leakage detection wire and a second leakage detection wire of a second detection body are spaced apart. The first leakage detection wire is provided with a plurality of first detection pieces 13 extending toward the second leakage detection wire on its side, and the second leakage detection wire is provided with a plurality of second detection pieces 14 extending toward the first leakage detection wire on its side. When leakage contacts the first detection piece 13 and the second detection piece 14, or when leakage contacts the first leakage detection wire and the second detection piece 14, or when leakage contacts the first leakage detection wire and the second detection piece 14, a leakage can be detected as a short circuit. Therefore, the first detection piece 13 and the second detection piece 14 can increase the detection range of the leakage detection sensor. The plurality of first detection pieces 13 and the plurality of second detection pieces 14 are spaced apart and staggered in sequence. The plurality of first detection pieces 13 can be evenly spaced along the length of the first leakage detection wire, and the plurality of second detection pieces 14 can be evenly spaced along the length of the second leakage detection wire.

[0041] It should be noted that the first detection piece 13 and the second detection piece 14 may be a rectangular structure or other shapes, as long as they are continuous structures extending from the sides of the first leakage detection wire and the second leakage detection wire.

[0042] The embodiment of the present invention also provides a liquid leakage detection device, which can be used for liquid leakage detection of a liquid cooling device. The liquid cooling device can be used for cooling a server. In addition, the liquid cooling device can also be used for cooling other electronic devices with heating devices. The liquid leakage detection position of the liquid cooling device includes a delivery pipe, a liquid cooling plate, and a joint position of the delivery pipe and the liquid cooling plate. The delivery pipe is used to deliver the coolant, and the leakage at the joint position can fall into the liquid collecting tank. Therefore, the first leakage detection unit 10 can realize the leakage detection of the delivery pipe, and the second leakage detection unit 20 can realize the liquid cooling. Liquid leakage detection at the plate and joint positions, the liquid leakage detection equipment includes the liquid leakage detection sensor provided by any of the above embodiments, and also includes a liquid leakage collector connected to the liquid leakage detection sensor, the liquid leakage collector can collect the signal that the first leakage detection wire and the second leakage detection wire of the liquid leakage detection sensor are connected through leakage. Specifically, the liquid leakage collector includes a detection circuit, and a resistor is provided on the detection circuit. The liquid leakage detection sensor is connected in parallel with the resistor. When the liquid leakage detection sensor is short-circuited, the current of the detection circuit will pass through the liquid leakage detection sensor. At this time, it can be determined that there is a leakage problem in the liquid cooling device.

[0043] 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.

[0044] 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.

The description of the above examples is only intended to help understand the core concept of the present invention.
