Description
Technical Field
[0001] The utility model relates to the technical field of liquid cooling devices for electronic equipment, in particular to a pipeline leakage prevention structure, a liquid cooling device and electronic equipment. Background Art
[0002] Liquid cooling plates are a mature cooling solution widely used for electronic equipment. However, since they use fluid as the heat dissipation medium, there is a risk of leakage at pipe joints, weld seams, and when sharp objects pierce the pipes during installation. If the liquid comes into direct contact with electronic components, it can cause a single server to shut down at best, or even cause a short circuit and burn in the computer room. Therefore, preventing leakage during use of liquid cooling plates has always been a pressing issue for electronic equipment liquid cooling solutions and is key to maintaining high reliability. Utility Model Content
[0003] The main purpose of the utility model is to provide a pipeline leakage prevention structure, a liquid cooling device and an electronic device, and to provide a pipeline leakage prevention solution for a liquid cooling device of an electronic device.
[0004] To achieve the above-mentioned purpose, the present invention proposes a pipeline leakage prevention structure for a liquid cooling device, wherein the pipeline leakage prevention structure comprises:
[0005] a liquid receiving container, arranged below the liquid separator of the liquid cooling device and arranged at least corresponding to the connecting joint on the liquid separator to receive the cooling liquid leaking from the connecting joint; and
[0006] The liquid discharge pipe is connected to the liquid receiving container to discharge the received cooling liquid.
[0007] In the technical solution of the present utility model, a pipeline leak-proof structure for a liquid cooling device is proposed. Specifically, the pipeline leak-proof structure includes the liquid holding container and the liquid drain pipe. The liquid holding container is arranged below the liquid separator of the liquid cooling device and corresponds to the connection joint on the liquid separator. When there is leakage at the connection joint, the liquid leaking out is received by the liquid drain, thereby preventing the liquid from contacting the electronic devices in the electronic device and playing a protective role. On this basis, the liquid holding container is also connected to the liquid drain pipe to discharge the liquid held in the liquid holding container through the liquid drain pipe. On the one hand, it avoids overflowing from the liquid holding container when the liquid leaks a lot, and on the other hand, it avoids the situation where the staff has a short reaction time when the liquid leaks quickly and is difficult to control in time. In summary, a certain leak-proof effect is achieved by the pipeline leak-proof structure to meet functional requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Liquid cooling plates are a mature cooling solution widely used for electronic equipment. However, since they use fluid as the heat dissipation medium, there is a risk of leakage at pipe joints, weld seams, and when sharp objects pierce the pipes during installation. If the liquid comes into direct contact with electronic components, it can cause a single server to shut down at best, or even cause a short circuit and burn in the computer room. Therefore, preventing leakage during use of liquid cooling plates has always been a pressing issue for electronic equipment liquid cooling solutions and is key to maintaining high reliability.
[0023] In view of this, the present invention proposes a pipeline leakage prevention structure, please refer to Figures 1 to 7 , is an embodiment of the pipeline leakage prevention structure proposed in this application, and the pipeline leakage prevention structure will be described in detail below with reference to specific drawings.
[0024] See also Figures 5 to 7The pipeline leakage prevention structure 100 includes a liquid holding container and a liquid drain pipe 2. The liquid holding container is used to be arranged below the liquid separator 300 of the liquid cooling device 1000a, and is arranged at least corresponding to the connecting joint 302 on the liquid separator 300 to receive the cooling liquid leaked from the connecting joint 302; the liquid drain pipe 2 is connected to the liquid holding container to discharge the received cooling liquid.
[0025] In the technical solution of the present utility model, a pipeline leak-proof structure 100 for a liquid cooling device 1000a is proposed. Specifically, the pipeline leak-proof structure 100 includes the liquid holding container and the drain pipe 2. The liquid holding container is arranged below the liquid separator 300 of the liquid cooling device 1000a and is arranged corresponding to the connection joint 302 on the liquid separator 300. When there is leakage at the connection joint 302, the leaked coolant is received, thereby preventing the coolant from contacting the electronic devices in the electronic device and playing a protective role. On this basis, the drain pipe 2 is also connected to the liquid holding container to discharge the coolant received in the liquid holding container through the drain pipe 2. On the one hand, it avoids overflowing from the liquid holding container when the coolant leaks a lot, and on the other hand, it avoids the situation where the coolant leaks quickly and the staff has a short reaction time and is difficult to control in time. In summary, the pipeline leak-proof structure 100 can achieve a certain leak-proof effect and meet functional requirements.
[0026] Specifically, the liquid-receiving container includes a main liquid-receiving container 11 and a sub-liquid-receiving container 12. The sub-liquid-receiving container 12 is arranged on the peripheral side of the main liquid-receiving container 11 and is connected to the main liquid-receiving container 11. The main liquid-receiving container 11 is used to be arranged below the main body 301 of the liquid dispenser 300, and the sub-liquid-receiving container 12 is used to be arranged below the connecting joint 302 connecting the main body 301 of the liquid dispenser 300. It can be understood that the liquid separator 300 is generally provided with multiple connecting joints 302, and the liquid holding container is set to be set separately corresponding to each connecting joint 302. Obviously, the structure is more complicated and inconvenient to install and fix. In this embodiment, the liquid holding container is set as the main liquid holding container 11 and the sub-liquid holding container 12 located on the side of the main liquid holding container 11. The sub-liquid holding container 12 is correspondingly arranged below the connecting joint 302 to receive the coolant leaked from the connecting joint 302, and the sub-liquid holding container 12 is communicated with the main liquid holding container 11 to collect the leaked coolant to the main liquid holding container 11, and then discharged by the drain pipe 2 connected to the main liquid holding container 11, and the main liquid holding container 11 is an integral structure arranged below the liquid separator 300, so that the overall structure of the pipeline leakage prevention structure 100 is simpler and more convenient for installation and fixation of the liquid holding container.
[0027] Specifically, the main liquid-receiving container 11 is funnel-shaped, and the sub-liquid-receiving container 12 is tilted at the edge of the main liquid-receiving container 11. To facilitate the smooth discharge of leaked coolant from the liquid-receiving container through the drain pipe 2 after being received by the liquid-receiving container, thereby preventing the leaked coolant from accumulating in the liquid-receiving container, the present embodiment configures the main liquid-receiving container 11 as a funnel-shaped structure, i.e., the bottom is tilted to form a collection area, so that the coolant can flow to the collection area on the main liquid-receiving container 11 under the influence of gravity. Similarly, the sub-liquid-receiving container 12 is tilted at the edge of the main liquid-receiving container 11, also utilizing the influence of gravity to allow the coolant to flow naturally from the sub-liquid-receiving container 12 to the main liquid-receiving container 11. Combined with the funnel-shaped main liquid-receiving container 11, the coolant received by the liquid-receiving container can flow toward the predetermined collection area. At the same time, the drain pipe 2 is configured to connect to this area, so that the coolant can be discharged in a timely manner, thus meeting the functional requirements of the pipeline leakage prevention structure 100.
[0028] In addition, there are at least two liquid holding containers, which include a first liquid holding container 1a and a second liquid holding container 1b; the drain pipe 2 is connected to the second liquid holding container 1b, and the first liquid holding container 1a and the second liquid holding container 1b are connected through a connecting pipe 3. It can be understood that the liquid cooling device 1000a may be provided with multiple liquid separators 300, and conventionally there are generally two, namely, a liquid separator 300 for separating the coolant at the coolant inlet end, and a liquid separator 300 for collecting the coolant at the coolant outlet end. Regardless of the specific number of liquid separators 300, each liquid separator 300 is correspondingly provided with a liquid holding container to meet the needs of receiving leaked coolant. At this time, the drain pipe 2 can be provided corresponding to each liquid holding container, that is, in a one-to-one correspondence, to meet the required functions, but it is obvious that the structure is more complicated, the installation operation is cumbersome and the cost is high. Therefore, in this embodiment, the multiple liquid holding containers are connected by the connecting pipe 3, and then discharged uniformly by a drain pipe 2, so as to simplify the pipeline leak-proof structure 100. Specifically, the connecting pipe 3 is provided between the first liquid holding container 1a and the second liquid holding container 1b for connection, and then discharged uniformly by the drain pipe 2.
[0029] Specifically, the bottom height of the first liquid-holding container 1a is higher than the bottom height of the second liquid-holding container 1b. To ensure that the coolant held in the first liquid-holding container 1a can flow smoothly through the connecting pipe 3 to the second liquid-holding container 1b and then be discharged through the drain pipe 2, in this embodiment, the heights of the first liquid-holding container 1a and the second liquid-holding container 1b are limited. That is, the bottom height of the first liquid-holding container 1a is higher than the bottom height of the second liquid-holding container 1b. This allows the connecting pipe 3 to have a certain inclination angle, thereby utilizing the effect of gravity to allow the coolant to naturally flow along the designed flow direction, thereby meeting the above-mentioned structural and functional requirements.
[0030] Furthermore, the drain pipe 2 is connected to the bottom of the liquid container. It is understood that the location of the drain pipe 2 on the liquid container is not limited, as long as its opening is below the highest liquid level in the liquid container, thereby preventing the collected coolant from overflowing the liquid container. In this embodiment, the drain pipe 2 is directly disposed at the bottom of the liquid container to prevent coolant from accumulating within the container and thereby provide a stable leak-proof effect.
[0031] In addition, the pipeline leakage prevention structure 100 also includes a leakage detection device, which is arranged in the liquid holding container and / or the drain pipe 2. While the liquid holding container receives the leaked coolant, the present application also provides the leakage detection device in the liquid holding container and the drain pipe 2 to monitor the leakage in real time, so as to obtain the leakage situation and leakage amount information in the first time and promptly remind the staff, thereby giving the staff a longer response time and facilitating timely control by the staff.
[0032] See also Figures 2 to 4 The present invention also proposes a liquid cooling device 1000a, which includes a plurality of liquid cooling plates 200, a liquid separator 300, and a pipeline leak-proof structure 100. The specific structure of the pipeline leak-proof structure 100 is referred to the above embodiment. Since the liquid cooling device 1000a adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The liquid separator 300 includes a main body 301 and a plurality of connecting joints 302. The plurality of connecting joints 302 include a plurality of liquid separation joints 302a connected to the main body 301 and a liquid collection joint 302b. The liquid separation joints 302a are respectively connected to the corresponding liquid cooling plates 200 through liquid separation pipes, and the liquid collection joint 302b is connected to a liquid collection pipe 303.
[0033] Specifically, the liquid-receiving container includes a main liquid-receiving container 11 and a sub-liquid-receiving container 12, the sub-liquid-receiving container 12 is arranged on the peripheral side of the main liquid-receiving container 11 and is connected to the main liquid-receiving container 11; the multiple connecting joints 302 are arranged on the side of the main body 301, and the multiple liquid-separating joints 302a are arranged on the same side of the main body 301; the main liquid-receiving container 11 is arranged below the main body 301 and laterally extends beyond the main body 301 to be placed below the multiple liquid-separating joints 302a, and the sub-liquid-receiving container 12 is arranged below the liquid collecting joint 302b. The liquid-receiving container includes the main liquid-receiving container 11 and the sub-liquid-receiving container 12, which have been described above. Specifically, the liquid separator 300 generally has multiple liquid-receiving joints 302a, and multiple liquid-receiving joints 302a are located on the same side of the liquid separator 300. If a sub-liquid-receiving container 12 is set up for each of them, the structure is obviously more complicated. Therefore, in this embodiment, the main liquid-receiving container 11 is directly set to be laterally beyond the main body 301, so that the main liquid-receiving container 11 can directly correspond to multiple liquid-receiving joints 302a, which is simple and practical. Of course, the main liquid-holding container 11 can also be set to correspond to multiple liquid-dispensing joints 302a while also corresponding to the liquid-collecting joint 302b. However, generally, the liquid-collecting joint 302b is set to one, and directly receiving the liquid through the main liquid-holding container 11 will cause the main liquid-holding container 11 to be larger in size and higher in cost. The sub-liquid-holding container 12 is set to receive the liquid-collecting joint 302b, thereby reducing the size of the main body 301 of the liquid-holding container and reducing costs.
[0034] See also Figure 1 The present invention also provides an electronic device 1000, comprising a housing 1000b and a liquid cooling device 1000a. The specific structure of the liquid cooling device 1000a is similar to that of the aforementioned embodiments. Since the electronic device 1000 utilizes all of the technical solutions of all of the aforementioned embodiments, it possesses at least all of the beneficial effects brought about by the technical solutions of the aforementioned embodiments, and therefore will not be further detailed here. The housing 1000b houses an electronic device, including a chip; the liquid cooling plate 200 is attached to the chip, and the drain pipe 2 extends outside the housing 1000b.
