Description

Technical Field

[0001] The utility model relates to the technical field of pipeline monitoring, and in particular to a pipeline liquid leakage detection device and a pipeline component for a liquid cooling system. Background Art

[0002] In information technology equipment, high-performance computing systems, and other occasions where efficient heat dissipation is required, immersion liquid cooling systems are often used for heat dissipation. The system uses cooling oil as a medium to absorb the heat generated by the equipment, which is then transported through pipes to a remote heat exchanger for heat dissipation and cooling, and then circulated back to the equipment.

[0003] However, there is a certain distance between the connecting pipes of the heat dissipation equipment and the heat exchanger, which requires multiple pipes and flanges to be connected. This connection method may have the problem of loose sealing, resulting in liquid leakage. If this situation cannot be monitored in time and an alarm is not issued, the amount of cooling oil used to absorb heat will be reduced, thus affecting the heat dissipation effect.

[0004] At present, due to the lack of special leak detection devices in the pipelines of immersion liquid cooling systems, small or slow leaks are often difficult to detect in time, and are not detected until the leakage volume accumulates to a certain level, at which time damage may have already occurred to the equipment.

[0005] Most of the leakage detection of cooling oil pipelines relies on regular manual inspections, which cannot achieve real-time monitoring and cannot respond to sudden leakage incidents in a timely manner.

[0006] Therefore, technicians in this field need to provide a pipeline leakage detection device for the pipelines of the immersion liquid cooling system, which can effectively and timely monitor pipeline leakage and reduce the impact. Utility Model Content

The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] In the description of the present invention, unless otherwise specified, "plurality" means two or more, and "several" means one or more.

[0031] References to "one embodiment" or "an example" or "an example" in this specification mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment disclosed in the present utility model. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0032] In a liquid cooling system, the coolant is transported through a seamless steel pipe. The pipe itself will not leak. However, the connection between pipes is currently mainly achieved by flange docking. In the process of connecting the pipe and the flange, welding is used to ensure the firmness and sealing of the connection. After welding, the factory will conduct an air pressure test to verify the sealing of the weld to ensure that no leakage occurs. Although the welding connection between the pipe and the flange has been rigorously tested, the bolted connection between the flanges may still cause leakage due to uneven tightening. Therefore, in order to respond promptly to leakage at the bolted connection on the pipe flange and reduce the impact, this embodiment provides a pipe leakage detection device for a liquid cooling system, which is installed at the connection between the pipe flange and the flange, and can perform leakage detection to capture leakage at these key locations.

[0033] like Figure 1 , Figure 2 and Figure 3As shown, in a first aspect, this embodiment provides a pipeline leakage detection device for a liquid cooling system, comprising an oil receiving container 100, a fixing member 200, and an oil leakage detection assembly 310. The fixing member 200 is configured to be mounted on a pipeline flange 400. When the fixing member 200 is mounted on the pipeline flange 400, it is fixed relative to the pipeline, including circumferential fixation, radial fixation, and axial fixation.

[0034] The oil receiving container 100 has an opening 120 facing the pipeline flange 400 and a connecting portion 110 located at the opening. The opening has a certain shape and size, the opening 120 faces upward, and the pipeline flange 400 is located above the oil receiving container 100.

[0035] The oil receiving container 100 is connected to the fixing member 200 through the connecting portion 110, so as to be suspended below the pipeline flange 400 and fixed without moving. The oil leakage detection component 310 is disposed in the oil receiving container 100 and is used to detect whether there is oil in the oil receiving container 100. The oil leakage detection component 310 is connected to the liquid cooling system to send the detection result to the liquid cooling system after detecting oil leakage.

[0036] In this embodiment, the pipeline leakage detection device is applied to the pipeline of the liquid cooling system. Once the bolts on the pipeline flange 400 leak, the oil will drip downward under the action of gravity, and finally fall into the opening 120 and gather in the oil receiving container 100. When the oil level gathered at the bottom of the oil receiving container 100 accumulates to a predetermined height, the oil leakage detection component 310 installed therein will be triggered. After the oil leakage detection component 310 detects the presence of oil, it will start an alarm in the system to promptly remind the maintenance personnel that a leakage has occurred at a specific flange connection.

[0037] In addition to detecting leakage, the oil receiving container 100 of the device also has the function of storing leakage, which can prevent the oil from spreading to other areas and reduce possible environmental pollution and the impact on equipment operation.

[0038] The pipeline leakage detection device can effectively monitor and report leakage events at flange connections, ensuring the tightness and reliability of the coolant system, while simplifying maintenance work and improving system maintenance efficiency.

[0039] In some embodiments, the oil leakage detection assembly 310 includes a photoelectric sensor. The photoelectric sensor is disposed on the side wall of the oil receiving container 100 , and a probe of the photoelectric sensor is aligned with the bottom wall of the oil receiving container 100 .

[0040] Specifically, the bottom wall of the oil receiving container 100 is a plane. Usually, after the oil receiving container 100 and the fixing member 200 are fixed, the bottom wall is set horizontally. During the actual installation process, since the four bolts installed on the pipeline flange 400 are not fixed at the specified position, but there is a certain angle error, the bottom wall of the oil receiving container 100 is tilted to one side in the horizontal radial direction of the pipeline. The oil receiving container 100 is provided with mounting grooves for installing photoelectric sensors on two opposite side walls in the radial direction of the pipeline. According to the tilt direction of the bottom wall of the oil receiving container 100, after the photoelectric sensor is selectively installed on one side, the probe of the photoelectric sensor is aligned with the lowest side of the bottom wall of the oil receiving container 100, so that the oil can be detected as soon as possible after leakage occurs.

[0041] In some embodiments, after the oil receiving container 100 and the fixing member 200 are fixed, the bottom wall thereof is arranged horizontally. In order to obtain the detection result faster or the time of obtaining the detection result is not affected by the angle of the bottom wall of the oil receiving container 100, the oil leakage detection assembly includes two photoelectric sensors. The two photoelectric sensors are respectively arranged on two opposite side walls of the oil receiving container 100 and the probes of the two photoelectric sensors are both aimed at the bottom wall of the oil receiving container 100. The two opposite side walls of the oil receiving container 100 are located in the radial direction of the pipeline. In this way, no matter whether the bottom wall of the oil receiving container 100 is horizontal or tilted to one side, the oil falling into the bottom wall of the oil receiving container 100 can be detected by one of the photoelectric sensors at the first time after leakage occurs.

[0042] In some embodiments, an escape notch 500 is formed between the opening 120 of the oil receiving container 100 and the fixing member 200, and the escape notch 500 located between the two together constitutes a through hole for the pipeline to pass through. The opening direction of the through hole is the same as the axial direction of the pipeline. In this embodiment, the fixing member 200 adopts a fixed cover structure, which is semi-cylindrical as a whole, its axial direction is the same as the axial direction of the pipeline, its radius is larger than the diameter of the pipeline flange 400, and it has a cover opening facing downward. The escape notch 500 on the fixing member 200 is a semicircular hole set on the cover opening and has the same diameter as the pipeline.

[0043] Similarly, the avoidance notch 500 on the oil receiving container 100 is a semicircular hole on the opening 120 of the oil receiving container 100. The connecting portion 110 is disposed on the oil receiving container 100, avoiding the avoidance notch 500 and connected to the fixing member 200.

[0044] In some embodiments, the fixing member 200 has two opposite side walls along the opening direction of the through hole, and the avoidance notch 500 of the fixing member 200 is arranged on the two opposite side walls. The avoidance notch 500 of the fixing member 200 is provided with a notch 210 extending along the radial direction of the through hole, corresponding to the bolt position on the pipeline flange 400, so as to be circumferentially limited with the pipeline through the notch 210.

[0045] In some embodiments, Figure 4 As shown, the connecting portion 110 includes a hinge portion 111 and a fastening portion 112. In the radial direction of the through hole, the hinge portion 111 and the fastening portion 112 are respectively on both sides of the avoidance gap 500 of the oil receiving container 100. The hinge portion 111 is hinged to the fixing member 200, and the fastening portion 112 is detachably connected to the fixing member 200, for example, by a threaded fastener.

[0046] In some alternative embodiments, the connection portion may also adopt two fastening portions, and the oil receiving container is detachably connected to the fixing piece on the pipeline flange through threaded fasteners on the two fastening portions.

[0047] In some embodiments, the size of the opening 120 is larger than the size of the flange on the pipeline. That is, the projection of the pipeline flange arranged axially and horizontally on the horizontal plane can completely fall within the opening. Specifically, the opening 120 is rectangular and has a length and a width, and its width direction is in the same direction as the axial direction of the pipeline, and its length direction is in the same direction as the horizontal radial direction of the pipeline. The length of the opening 120 is larger than the diameter of the pipeline flange 400, and the width of the opening 120 is larger than the spacing between the two opposite surfaces of the pipeline flange 400.

[0048] In some embodiments, the pipeline leakage detection device further includes an alarm signal generator. The oil leakage detection component 310 is electrically connected to the alarm signal generator, and when the oil in the oil receiving container 100 is detected, the alarm signal generator sends an alarm signal.

[0049] In some embodiments, the alarm signal generator includes a sound generating component for generating an audible alarm signal. The alarm signal generator is disposed near the oil receiving container 100, the fixing member 200 or the pipeline flange 400 (not shown in the figure). When the audible alarm signal appears, the maintenance personnel can quickly find the specific location of the leakage according to the audible alarm signal.

[0050] In some embodiments, the alarm signal generator includes a light emitting component. The light source of the light emitting component is disposed on the outer surface of one of the oil receiving container 100, the fixing member 200 and the pipeline flange 400 (not shown in the figure) to emit a light alarm signal.

[0051] At the same time, the present embodiment also provides a pipeline assembly in a second aspect, such as Figure 5 As shown, the pipeline assembly includes two connected pipelines and the pipeline leakage detection device described in the first aspect, the two pipelines are connected by a pipeline flange 400, and the fixing part 200 of the pipeline leakage detection device is installed on the pipeline flange between the two pipelines, with the opening facing the upper pipeline flange.

[0052] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present invention shall be included in the scope of the claims.
