Abstract
Description
Technical Field
[0001] The present application relates to the technical field of cold plate liquid cooling, and in particular to a liquid collecting device. Background Art
[0002] At present, with the development of server motherboard cooling technology, cold plate liquid cooling technology has become the mainstream cooling technology for servers.
[0003] In the existing system, the cold plate liquid cooling device includes a cold plate, a liquid guiding pipeline and a joint. The liquid guiding pipeline is connected to the cold plate through the joint to supply liquid cooling medium to the cold plate, so that the cold plate contacts the heat-generating components such as the motherboard to achieve heat dissipation for the motherboard.
[0004] Generally speaking, the joint is a pagoda joint, which is inserted into the liquid guiding pipeline through a multi-level pagoda structure and sealed with the liquid guiding pipeline. However, due to the inevitable defects in the product processing and installation process, there is still a risk of leakage. At the same time, there is also a certain risk of leakage in the liquid guiding pipeline, which will cause great hidden dangers to the hardware and data security of the server. At present, most of the protection against the above leakage is to use a liquid storage sleeve, that is, a liquid storage sleeve is installed outside the liquid guiding pipeline and the joint to store the leaked liquid in the liquid storage sleeve when leakage occurs.
[0005] However, in the process of implementing the present invention, the inventors found that there are at least the following problems in the prior art:
[0006] The installation of the liquid storage sleeve is complicated, and the direct connection between the liquid storage sleeve and the joint is prone to leakage. The leaked liquid will flow out of the liquid storage sleeve, resulting in poor leakage prevention effect and failure to meet the leakage prevention requirements of the server. In addition, due to the existence of internal pressure, when the leaked liquid stored in the liquid storage sleeve reaches a certain amount, the liquid storage sleeve will also have a certain risk of leakage.
[0007] Therefore, it is necessary for those skilled in the art to provide a liquid collecting device in a timely manner that can collect leaked liquid generated by the pipelines and their connections at the cold plate position to meet the leakage prevention requirements of the server. Utility Model Content
[0008] The purpose of the present application is to provide a liquid collecting device, which can collect leaked liquid generated by the pipelines and their connections at the cold plate position to meet the leakage prevention requirements of the server.

[0014] The liquid collecting tray includes an annular protrusion structure, which protrudes toward a direction close to at least a portion of the pipeline assembly to form a liquid collecting tank;
[0015] The liquid collecting tray also includes a connecting plate, the annular protrusion structure is arranged on the connecting plate, and the connecting plate is connected to the cold plate.
[0016] In some embodiments, the pipeline assembly includes a liquid guiding pipeline and a leak-proof outer tube located outside the liquid guiding pipeline, and the inner wall of the leak-proof outer tube is provided with a leak-proof detection band.
[0017] In some embodiments, the cold plate includes a heated plate and a cover plate disposed on the heated plate, and the liquid collecting tank is a groove disposed on the cover plate.
[0018] In some embodiments, a guide structure is also included. The guide structure is arranged on the joint and cooperates with at least part of the pipeline assembly. The guide structure extends into the liquid collecting tank, so that the leaked liquid flowing out of at least part of the pipeline assembly flows into the liquid collecting tank after being guided by the guide structure.
[0019] In some embodiments, an outer cover is also included, and the outer cover is arranged on the liquid collecting tank to prevent the liquid cooling medium in the liquid collecting tank from leaking out.
[0020] In some embodiments, a liquid pumping mechanism is further included, and the liquid pumping mechanism is connected to the liquid collecting tank to extract the liquid cooling medium in the liquid collecting tank. The liquid pumping mechanism includes:
[0021] A liquid extraction pipe, one end of which extends into the liquid collecting tank;
[0022] A liquid extraction component, the liquid extraction component is connected to the liquid extraction pipe to extract the liquid cooling medium in the liquid collecting tank through the liquid extraction pipe;

[0026] It can be seen that, on the one hand, the liquid collecting port of the liquid collecting tank can cover the joint connected to the cold plate and at least part of the pipeline assembly, so that the liquid cooling medium leaked from at least part of the pipeline assembly can be collected by the liquid collecting tank, thereby ensuring that the leakage above the cold plate will not leak out; on the other hand, the liquid collecting tank is arranged on the outer periphery of the joint, even if the liquid cooling medium leaks at the connection position between the joint and the cold plate, under the action of the internal pressure of the joint and the cold plate, the leaked liquid cooling medium will eventually enter the liquid collecting tank, thereby ensuring that the leakage at the location of the cold plate will not leak out. Based on this, the liquid collecting device provided in the embodiment of the present application can collect leakage caused by the pipeline, the connection position between the cold plate and the joint due to structural factors, connection defects, etc., so as to meet the server's requirements for leakage protection, thereby improving the safety of server operation.

DETAILED DESCRIPTION
[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0035] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0036] It should be noted that the directional words such as "upper end, lower end, left side, right side" described below are all defined based on the drawings in the specification.
[0037] Please refer to Figures 1 to 4 , Figure 1 This is a schematic diagram of the structure of the liquid collecting device in the embodiment of the present application; Figure 2 for Figure 1 A top view of the liquid collecting device shown; Figure 3 for Figure 1 A cross-sectional view of the liquid collecting device shown; Figure 4 This is a schematic diagram of the assembled outer cover of the liquid collecting device in the embodiment of the present application.
[0038] The liquid collecting device provided in the embodiment of the present application includes a cold plate 1, and the cold plate 1 includes a heated plate 11 and a cover plate 12. The heated plate 11 and the cover plate 12 are connected to form a liquid cooling chamber for accommodating liquid cooling medium. The heated plate 11 is used to contact the working parts of the server, such as the mainboard, so as to achieve heat dissipation for the mainboard.
[0039] Furthermore, the liquid collecting device further includes a liquid collecting tank 2. Specifically, the liquid collecting tank 2 is used to be arranged at the periphery of the joint 3 connected to the cold plate 1, and the liquid collecting tank 2 is provided with a liquid collecting port 21, and the liquid collecting port 21 is arranged toward at least part of the pipeline assembly 4 connected to the joint 3, and the liquid collecting port 21 covers the position where the joint 3 and at least part of the pipeline assembly 4 are located, so that the liquid cooling medium leaked from at least part of the pipeline assembly 4 and the connection between the joint 3 and the cold plate 1 can be collected in the liquid collecting tank 2.
[0040] The pipeline assembly 4 includes an internal liquid guiding pipeline 41 and a leakproof outer tube 42 located outside the liquid guiding pipeline 41. A receiving cavity for storing leaked liquid is formed between the leakproof outer tube 42 and the liquid guiding pipeline 41. In addition, a leakproof detection belt is also provided on the inner wall of the leakproof outer tube 42.
[0041] It should be noted that the leakproof outer tube 42 can be an integrated tube, so as to be directly sleeved on the liquid guiding pipeline 41, but this will make the leakproof detection belt in the leakproof outer tube 42 inconvenient to install. Based on this, the leakproof outer tube 42 preferably includes a transparent belt rolled into a tubular shape and a self-sealing strip connecting the lateral edges of the transparent belt along the extension direction, so as to constrain the transparent belt through the self-sealing strip so that the transparent belt becomes a tubular structure. Of course, in addition to the above-mentioned self-sealing strip, the connection of the lateral edges of the transparent belt can also be other ways, such as buckling, gluing, etc. It should be emphasized that since the leaked liquid enters the leakproof outer tube 42, it will generally be in a low-pressure state, so the connection strength of the above-mentioned connection method can meet the needs. Of course, the transparent belt can also be a non-transparent belt, but the transparent belt is easier to observe.
[0042] Preferably, a liquid collecting tank 2 is provided below at least part of the piping assembly 4 connected to the joint 3, so that the liquid collecting tank 2 can be used to receive the liquid cooling medium leaked from at least part of the piping assembly 4, and the liquid collecting tank 2 can be used to collect the liquid cooling medium leaked from the connection between the joint 3 and the cold plate 1.
[0043] It should be noted that the liquid-cooling medium leaked from at least part of the pipeline assembly 4 mainly includes two parts. One part is the liquid-cooling medium leaked from the crack of the leak-proof outer tube 42 (the crack formed due to its own structure or connection defects, etc.), and this part of the liquid-cooling medium directly drips into the liquid collecting tank 2; the other part is the liquid-cooling medium leaked from the end opening of the leak-proof outer tube 42 (for example, leakage caused by connection defects between the liquid guide pipeline 41 and the joint 3). Since there is a gap between the end of the leak-proof outer tube 42 and the joint 3, the liquid-cooling medium leaked from the end opening of the leak-proof outer tube 42 can flow along the outer wall of the joint 3 to the liquid collecting tank 2.
[0044] It can be seen that, on the one hand, the liquid collecting port 21 of the liquid collecting tank 2 can cover the joint 3 and at least part of the pipeline assembly 4 connected to the cold plate 1, so that the liquid cooling medium leaked from at least part of the pipeline assembly 4 can be collected by the liquid collecting tank 2, thereby ensuring that the leakage at the position above the cold plate 1 will not leak out; on the other hand, the liquid collecting tank 2 is arranged on the periphery of the joint 3. Even if the liquid cooling medium leaks at the connection position between the joint 3 and the cold plate 1, under the action of the internal pressure of the joint 3 and the cold plate 1, the leaked liquid cooling medium will eventually enter the liquid collecting tank 2, thereby ensuring that the leakage at the position of the cold plate 1 will not leak out.
[0045] In this way, the liquid collection device provided in the embodiment of the present application can collect leakage caused by structural factors, connection defects, etc. in the pipeline and the connection position between the cold plate 1 and the joint 3, so as to meet the server's requirements for leakage protection and thereby improve the safety of server operation.
[0046] As can be seen from the above, in order to facilitate liquid collection, the above-mentioned liquid collection tank 2 can be arranged outside the cold plate 1, such as above the cold plate 1, or inside the cold plate 1, such as inside the cover plate 12 of the cold plate 1.
[0047] In some embodiments, the liquid collecting tank 2 is disposed separately from the cold plate 1 , and the liquid collecting tank 2 is disposed outside the cold plate 1 .
[0048] It is understandable that the liquid collecting tank 2 is separately provided from the cold plate 1, that is, a structure having the liquid collecting tank 2 can be separately provided on the cold plate 1, and such a setting does not affect the structure of the cold plate 1, and the cold plate 1 can be separately batch-formed. At the same time, the benefits of the separate setting also include: when the liquid collecting tank 2 is damaged or needs to be replaced, the liquid collecting tank 2 can be directly replaced without disassembling the cold plate 1, which greatly improves the efficiency of assembly and disassembly.
[0049] In this embodiment, the liquid collecting tank 2 can be formed by the liquid collecting structure and the cold plate 1 together, or can be formed by a liquid collecting structure alone, as described in detail below:
[0050] When the liquid collecting tank 2 is formed by the liquid collecting structure and the cold plate 1 , the liquid collecting device further comprises a ring 5 , which is arranged around the outer periphery of the joint 3 , and the ring 5 and the cold plate 1 together form the liquid collecting tank 2 .
[0051] Specifically, the enclosure 5 can be arranged around the cover plate 12, and in order to ensure the sealing of the connection between the enclosure 5 and the cover plate 12, a sealing ring is provided between the enclosure 5 and the cover plate 12 to seal the gap between the enclosure 5 and the cover plate 12. For example, a mounting groove can be provided on the outer wall of the cover plate 12, and the sealing ring is installed in the mounting groove, and the depth of the mounting groove is less than the thickness of the sealing ring. In this way, when the sealing ring is installed, the sealing ring is compressed by its own elasticity, thereby ensuring the gap between the sealing enclosure 5 and the cover plate 12.
[0052] In this case, the cover plate 12 of the cold plate 1 serves as the bottom surface of the liquid collecting tank 2, and the enclosure 5 is a closed-loop fence structure serving as the side surface of the liquid collecting tank 2, thereby forming the liquid collecting tank 2 capable of collecting leaked liquid.
[0053] When the liquid collecting tank 2 is formed by a liquid collecting structure alone, the liquid collecting device also includes a liquid collecting pan, which is arranged on the cold plate 1. The liquid collecting pan is provided with a through hole for the connector 3 to pass through, and the connector 3 is connected to the cold plate 1 after passing through the through hole; at the same time, the liquid collecting pan includes an annular protrusion structure, which protrudes in a direction close to at least part of the pipeline assembly 4 to form the liquid collecting tank 2.
[0054] On the basis of the above, the liquid collecting tray further comprises a connecting plate, the annular protrusion structure is arranged on the connecting plate, and the connecting plate is connected to the cold plate 1. The connecting plate and the cold plate 1 can be connected by a detachable connecting member (screw or bolt).
[0055] In this case, the connecting plate serves as the bottom surface of the liquid collecting tank 2, and the annular protruding structure is a closed-loop fence structure, serving as the side surface of the liquid collecting tank 2, thereby forming the liquid collecting tank 2 capable of collecting leaked liquid.
[0056] In some embodiments, the liquid collecting tank 2 and the cold plate 1 are an integrated structure, and the liquid collecting tank 2 is disposed inside the cold plate 1 .
[0057] Specifically, the cold plate 1 includes a heated plate 11 and a cover plate 12 disposed on the heated plate 11, and a recessed area or groove is disposed on the cover plate 12, and the groove is recessed in a direction away from at least part of the pipeline assembly 4. In this way, the liquid collecting tank 2 can be a groove disposed on the cover plate 12. The gap between the joint 3 and the cold plate 1 can be connected to the groove, so that the liquid cooling medium leaked from the gap between the joint 3 and the cold plate 1 can flow into the groove, ensuring that there is no leakage to the outside, which affects the operation safety of the working parts of the server.
[0058] In order to facilitate the diversion of liquid cooling medium leaking from the end opening of the leak-proof outer tube 42, the liquid collecting device also includes a diversion structure 31, which is arranged on the joint 3 and cooperates with at least part of the pipeline assembly 4 (for the case where the pipeline assembly 4 is arranged on one side of the joint 3, the diversion structure 31 and the pipeline assembly 4 are located on the same side of the joint 3), and the diversion structure 31 extends into the liquid collecting tank 2, so that the leaked liquid flowing out from the end opening of the leak-proof outer tube 42 flows into the liquid collecting tank 2 after being guided by the diversion structure 31.
[0059] It can be understood that, since there is a gap between the end of the leak-proof outer tube 42 and the joint 3, the liquid cooling medium leaking from the end opening of the leak-proof outer tube 42 can flow along the outer wall of the joint 3 to the liquid collecting tank 2. To this end, a guide structure 31 is provided on the outer wall of the joint 3, and the guide structure 31 can be a guide groove, which can be a linear structure or a curved structure, provided that it can ensure that the leaked liquid flowing out of the end opening of the leak-proof outer tube 42 is guided to the liquid collecting tank 2.
[0060] In order to prevent the leaked liquid in the liquid collecting tank 2 from leaking out, the liquid collecting device further comprises an outer cover 6 , which is disposed on the liquid collecting tank 2 to prevent the liquid cooling medium in the liquid collecting tank 2 from leaking out.
[0061] The outer cover 6 can be connected to the top of the liquid collecting tank 2 through a detachable connecting component (screws, bolts, etc.), and the outer cover 6 can cover the liquid collecting port 21 to prevent the liquid cooling medium in the liquid collecting tank 2 from leaking out from the liquid collecting port 21.
[0062] Of course, the outer cover 6 is provided with slots for the pipe assembly 4 to pass through, so as to facilitate the connection between the pipe assembly 4 and the cold plate 1 .
[0063] In order to further meet the server leakage protection requirements, the liquid collecting device also includes a liquid pumping mechanism 7, which is connected to the liquid collecting tank 2. The liquid pumping mechanism 7 is used to extract the liquid cooling medium in the liquid collecting tank 2 and concentrate the liquid cooling medium in the liquid collecting structure outside the cold plate 1 to prevent the liquid cooling medium in the liquid collecting tank 2 from exceeding the warning amount.
[0064] Specifically, the liquid extraction mechanism 7 includes a liquid extraction pipe, a liquid extraction assembly, a liquid leakage detection component, and a control component. Among them, one end of the liquid extraction pipe extends into the liquid collecting tank 2, the liquid extraction assembly is connected to the liquid extraction pipe, the liquid extraction assembly extracts the liquid cooling medium in the liquid collecting tank 2 through the liquid extraction pipe, the liquid leakage detection component is arranged in the liquid collecting tank 2 to detect the amount of the liquid cooling medium in the liquid collecting tank 2, the control component is electrically connected to the liquid leakage detection component and the liquid extraction assembly, and the control component is used to control the liquid extraction assembly to open when the amount of the liquid cooling medium in the liquid collecting tank 2 exceeds the warning amount and extract the liquid cooling medium in the liquid collecting tank 2 to the liquid collecting structure outside the cold plate 1.
[0065] That is to say, by adopting the above-mentioned liquid extraction mechanism 7, the liquid cooling medium in the liquid collecting tank 2 can be extracted when the amount of the liquid cooling medium in the liquid collecting tank 2 reaches a certain value, thereby facilitating the protection of the server equipment.
[0066] In some embodiments, the liquid leakage detection member may be a liquid leakage detection sensor, and the liquid leakage detection member may be a sheet-like structure, and the liquid leakage detection member of the sheet-like structure is entirely covered on the bottom surface of the liquid collecting tank 2. In this way, when liquid cooling medium appears at any position in the liquid collecting tank 2, the liquid leakage detection member can detect it in real time and feed back the detected data to the control component.
[0067] 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.
[0068] The above is a detailed introduction to the liquid collection device provided by the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the scheme of the present application and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
