Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation, and more specifically to a liquid cooling system and a server. Background Art

[0002] As the power density of servers increases, higher requirements are placed on heat dissipation. Liquid cooling heat exchange can provide higher heat exchange efficiency than air cooling heat exchange to meet the server heat exchange requirements. At present, the liquid cooling of servers is mainly cold plate liquid cooling. Cold plate liquid cooling is also called liquid cooling plate. The liquid cooling plate exchanges heat with high-heat generating components of the server, and then connects to the heat exchange device through a liquid guide pipe to quickly transfer heat to the outside of the server.

[0003] During the operation of the server, the liquid cooling system may leak due to fatigue, vibration and other reasons. If the electronic components of the server come into contact with the leaked high-pressure liquid, short circuits and other faults may occur. Therefore, it is necessary to detect whether the liquid cooling device has leaks, and shut down the system in time when a leak is detected. Usually, a detection belt is set under the liquid cooling system to detect leaks. When a leak is detected in the liquid cooling system, the system is shut down and the entire liquid cooling system is disassembled for repair. However, it is difficult to determine the leakage location of the liquid cooling system with the above method, and the overall disassembly and repair cost is high and the efficiency is low.

[0025] The utility model discloses a liquid cooling system and a server, so as to realize leakage detection at different positions of the liquid cooling system, so as to facilitate the partial disassembly and maintenance of the liquid cooling system when leakage is detected.

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

[0027] The liquid cooling system provided in the present application includes at least one liquid cooling body and at least one liquid conduit, and the liquid conduit is connected to the corresponding liquid cooling body. The liquid cooling body is generally a liquid cooling plate, and of course, in some states, it can also be a block or other structure. The liquid cooling body is used to exchange heat with the heating elements of electronic equipment such as servers. It can be understood that the heating elements here can include elements that generate heat themselves during operation such as processors, and can also include elements that absorb heat from elements that generate heat themselves and generate heat indirectly. At least one side of the liquid cooling body is a heating surface, which is used to abut against the electronic component to be dissipated. At this time, the heating surface of the liquid cooling body and the heat dissipation surface of the electronic component are in thermal contact.

[0028] The liquid guide tube in the present application is used to guide the high-temperature liquid in the liquid cooling body out and introduce the low-temperature liquid. It should be noted that the liquid in the liquid cooling body and the liquid guide tube in the present application can be either cooling water or refrigerant. The cooling water includes but is not limited to water or a mixture of water, such as antifreeze cooling water with ethylene glycol added, and the refrigerant includes but is not limited to a refrigerant with fluorine added. The liquid guide tube has an inlet channel and an outlet channel for liquid circulation, so that the high-temperature liquid in the liquid cooling body flows out and the low-temperature liquid flows in. It can be understood that it can include a separately arranged inlet pipe and an outlet pipe, or an integrated multi-lumen tube, and the different lumens of the multi-lumen tube are used for the inlet and outlet of the liquid. In the present application, the first detection belt and the second detection belt are respectively arranged for the liquid cooling body and the liquid guide tube, and through the reasonable layout of the two, the detection of the leakage position of the liquid cooling system is realized, and the corresponding local repair of the leakage position is facilitated. In the following embodiments, the setting method of the first detection belt and the second detection belt and the connection relationship of the liquid guide tube are mainly described. The other structures of the liquid cooling system can refer to the prior art and will not be repeated here.

[0029] In a specific embodiment, see Figure 1-Figure 2The liquid cooling system provided by the utility model comprises at least one liquid cooling body 1, at least one liquid conduit 2, a first detection band 3 provided on the liquid cooling body 1, and a second detection band 4 provided on the liquid conduit 2. The liquid conduit 2 is connected with the corresponding liquid cooling body 1, the first detection band 3 is used to detect the leakage of the liquid cooling body 1, the second detection band 4 is used to detect the leakage of the liquid conduit 2, and the second detection band 4 provided on at least one liquid conduit 2 is connected in series with the first detection band 3 provided on at least one liquid cooling body 1 connected with the liquid conduit 2. That is, at least one liquid conduit 2 is connected with at least one liquid cooling body 1, and the liquid conduit 2 and at least one of the liquid cooling bodies 1 connected with it serve as a detection branch, and the first detection band 3 provided on the detection branch are all connected in series with the second detection band 4, so that when any of the liquid conduit 2 or the liquid cooling body 1 on the detection branch leaks, it can be effectively detected, so that the liquid conduit 2 and the liquid cooling body 1 on the detection branch can be disassembled together for maintenance, or each liquid cooling body 1 connected with the liquid conduit 2 can be disassembled together as a disassembly unit for maintenance. Compared with each liquid guide tube 2 and each liquid cooling body 1 being used as a detection branch independently, the structure is simplified and the amount of processed data is reduced in the corresponding control process.

[0030] The liquid cooling system provided by the utility model is applied, by setting a first detection band 3 for detecting liquid leakage on the liquid cooling body 1, setting a second detection band 4 for detecting liquid leakage on the liquid guiding tube 2, and connecting the second detection band 4 provided on at least one liquid guiding tube 2 in series with the first detection band 3 provided on at least one liquid cooling body 1 connected to the liquid guiding tube 2. On the one hand, the above arrangement does not require the entire liquid cooling system to be disassembled during maintenance, thereby improving maintenance efficiency and reducing maintenance costs. On the other hand, the connected liquid guiding tube 2 and the liquid cooling body 1 do not need to be detected separately as a detection branch, thereby simplifying the structure and facilitating the layout of the pipeline.

[0031] In some embodiments, the liquid guide tube 2 includes a separately arranged liquid inlet pipe and a liquid outlet pipe, on which a second detection band 4 is respectively arranged, and the first detection band 3 on the liquid cooling body 1 connected between the liquid inlet pipe and the liquid outlet pipe is connected in series with the second detection band 4 on the liquid inlet pipe and the second detection band 4 on the liquid outlet pipe.

[0032] In some embodiments, the same liquid conduit 2 is connected to multiple liquid cooling bodies 1. The liquid cooling body 1 is used to exchange heat with the heating element. According to the heat dissipation requirements of the heating element, multiple liquid cooling bodies 1 can be connected to the same liquid conduit 2. Multiple liquid cooling bodies 1 can be connected in series or in parallel as needed. For high-heat-generating elements, multiple parallel liquid cooling bodies 1 can be set, that is, the liquid conduit 2 provides cooling to each liquid cooling body 1 separately, so that each liquid cooling body 1 can provide a higher heat exchange efficiency. For low-heat-generating elements, multiple series-connected liquid cooling bodies 1 can be set, and the liquid flows through each series-connected liquid cooling body 1 in turn to take away the heat of the low-heat-generating element, which not only meets the heat dissipation requirements, but also simplifies the pipeline structure and reduces energy consumption.

[0033] Furthermore, in the case where a plurality of liquid-cooling bodies 1 are connected to the same liquid-conducting tube 2, each first detection band 3 on the plurality of liquid-cooling bodies 1 connected to the same liquid-conducting tube 2 is connected in series with the second detection band 4 on the liquid-conducting tube 2. For the connected liquid-cooling bodies 1 and liquid-conducting tubes 2, it is convenient to disassemble and repair them as a detection branch, and only the two ends of the detection branch need to be disconnected and sealed respectively. Therefore, each first detection band 3 on the plurality of liquid-cooling bodies 1 connected to at least one liquid-conducting tube 2 is connected in series with the second detection band 4 on the liquid-conducting tube 2, that is, the first detection band 3 on each liquid-cooling body 1 connected to at least one liquid-conducting tube 2 is connected in series with the second detection band 4 on the liquid-conducting tube 2, thereby achieving a great simplification of the structure on the basis of facilitating individual maintenance.

[0034] In some embodiments, at least one liquid conduit 2 is connected in parallel with a plurality of liquid-cooled bodies 1, and the first detection bands 3 provided on each of the parallel liquid-cooled bodies 1 are connected in series. That is, the plurality of liquid-cooled bodies 1 connected by at least one liquid conduit 2 are connected in parallel. The liquid conduit 2 and the plurality of liquid-cooled bodies 1 connected in parallel thereon are used as a detection branch, and the first detection bands 3 in the detection branch are all connected in series with the second detection bands 4. Each first detection band 3 in the detection branch is connected in series with the second detection band 4, so as to facilitate the connection between two adjacent first detection bands 3 and / or second detection bands 4. Specifically, taking the example of two liquid-cooling bodies 1 connected in parallel on the liquid-conducting tube 2, for the convenience of explanation, the two liquid-cooling bodies 1 are recorded as the first liquid-cooling body and the second liquid-cooling body, and the portion of the liquid-conducting tube 2 before being connected with the first liquid-cooling body is recorded as the first liquid-conducting part, and the portion connected between the first liquid-cooling body and the second liquid-cooling body is recorded as the second liquid-conducting part, then the second detection band 4 on the first liquid-conducting part is first connected in series with the first detection band 3 on the first liquid-cooling body, and the first detection band 3 on the first liquid-cooling body is then connected in series with the second detection band 4 on the second liquid-conducting part, and the second detection band 4 on the second liquid-conducting part is then connected in series with the first detection band 3 on the second liquid-cooling body, thus forming a detection branch. When the first liquid-conducting part includes a first liquid inlet pipe and a first liquid outlet pipe that are separately arranged, and the second liquid-conducting part includes a second liquid inlet pipe and a second liquid outlet pipe that are separately arranged, the second detection band 4 is arranged on both of them. Specifically, the second detection band 4 on the first liquid inlet pipe is first connected in series with the first detection band 3 on the first liquid cooling body, the first detection band 3 on the first liquid cooling body is then connected in series with the second detection band 4 on the second liquid inlet pipe, the second detection band 4 on the second liquid inlet pipe is then connected in series with the first detection band 3 on the second liquid cooling body, the first detection band 3 on the second liquid cooling body is connected in series with the second detection band 4 on the second liquid outlet pipe, and the second detection band 4 on the second liquid outlet pipe is connected in series with the second detection band 4 on the first liquid outlet pipe. In other embodiments, the first detection bands 3 provided on each parallel liquid cooling body 1 can also be connected in parallel and respectively connected in series with the second detection band 4 on the liquid guiding tube 2, and can also be used as a detection branch for detection.

[0035] In some embodiments, the second detection belt 4 is provided with a first joint at the position corresponding to the connection between the liquid guide tube 2 and the liquid cooling body 1, and the second detection belt 4 is provided with a second joint that is docked with the first joint. By providing the first joint and the second joint, the first detection belt 3 and the second detection belt 4 are laid at the corresponding position during assembly, and are connected in series through the first joint and the second joint, which is convenient to operate, and there is no need to adjust or destroy the structure of the first detection belt 3 and the second detection belt 4 during assembly.

[0036] In some embodiments, see Figure 3, the first detection band 3 and the second detection band 4 both include two detection wires 51 with a circuit-breaking setting, and the two detection wires 51 of the first detection band 3 and the second detection band 4 connected in series are respectively connected in series as a group, and each group of detection wires 51 with a circuit-breaking setting is respectively used to connect to the collector to collect the electrical signals between each group of detection wires 51. The circuit-breaking setting here means that the two detection wires 51 are not connected, and when the liquid cooling system leaks, such as when the liquid cooling body 1 leaks, the two detection wires 51 of the first detection band 3 are connected due to the presence of liquid, so that the collector can directly or indirectly collect the resistance between the two detection wires 51 or the electrical signals such as the current applied between the two wires, and the change of the electrical signals such as the resistance or the current can determine whether the corresponding liquid cooling body 1 leaks. In this embodiment, the first detection band 3 and the second detection band 4 are connected in series by connecting the two detection wires 51 in series, and the structure is simple and easy to assemble. It can be understood that each group of detection wires 51 with a circuit break is used to connect to the collector, including only two detection wires 51 connected in series as a group, and multiple groups of detection wires 51 connected in series are used to connect to the collector. In the case where the first detection band 3 is not connected in series with the second detection band 4 in the liquid cooling system, that is, the first detection band 3 or the second detection band 4 is set separately, it is also possible to treat the two detection wires 51 connected in series as a group, and the two detection wires 51 of the first detection band 3 set separately as a group, and the two detection wires 51 of the second detection band 4 set separately as a group, then each group of detection wires 51 is connected to the collector, and the collector collects the electrical signals between each group of detection wires 51 to determine whether the detection position corresponding to each group of detection wires 51 has a leak.

[0037] In some embodiments, see Figure 3 , a detection sheet 52 extending toward the other is provided on any one of the two detection wires 51 of each group, and the detection sheets 52 on the two detection wires 51 are arranged at intervals. It can be understood that the detection sheets 52 on the two detection wires 51 are arranged at intervals, including that the detection sheets 52 on the two detection wires 51 are not in contact with each other, and that the detection sheet 52 on any detection wire 51 is not in contact with the other detection wire 51. When performing detection, when the leaking liquid contacts the two detection sheets 52 at the same time, or contacts the detection sheet 52 on one detection wire 51 and the other detection wire 51 at the same time, or contacts the two detection wires 51 at the same time, the leakage problem can be detected. By setting the detection sheet 52, the distance between the two detection wires 51 can be increased to increase the detection area, and the detection accuracy can be guaranteed by setting the distance between the detection sheets 52. The smaller the distance between the specific detection sheet 52 and the detection wire 51, the higher the detection accuracy.

[0038] Furthermore, the detection pieces 52 on the two detection wires 51 of each group are alternately distributed, and a preset spacing is left between them. Specifically, the detection pieces 52 on each detection wire 51 are distributed in a comb-like shape, and the width of the detection pieces 52 on the two detection wires 51 can be greater than, less than, or equal to half of the spacing between the two detection wires 51. It should be noted that, Figure 3 The detection sheet 52 shown is a rectangular structure, but may also be a triangle, trapezoid, L-shaped, T-shaped or other shapes. The detection sheet 52 only needs to be a structure that protrudes from one detection wire 51 toward another detection wire 51 .

[0039] In some embodiments, each group of detection wires 51 with disconnected settings is used to connect to different collectors to separately collect electrical signals between each group of detection wires 51. By connecting each group of detection wires 51 with disconnected settings to corresponding collectors, it is possible to directly determine whether the position of the corresponding group of detection wires 51 has a leak based on the changes in the electrical signals collected by each collector, which is convenient to determine and quick to respond.

[0040] In some embodiments, resistors with different resistances are connected between the two detection wires 51 of at least two groups of disconnection settings, and the resistors are connected in series, and the first and last ends of the series resistors are used to connect to the collector to collect the electrical signals between the first and last ends. It can be understood that the electrical signals between the first and last ends of the series resistors can be the detection resistance value between the first and last ends, or the detection current value applied between the first and last ends. In the above embodiment, the collectors corresponding to the detection wires 51 of each group of disconnection settings respectively detect the resistance between the detection wires 51 of each group of disconnection settings or the current and other electrical signals applied between the two wires. When the two detection wires 51 of each group of disconnection settings are connected due to liquid leakage, the resistance or current and other electrical signals change, thereby determining whether the corresponding detection branch has leaked. The difference between this embodiment and the above embodiment is that there is no need to set a collector separately for each group of disconnection settings. The detection wires 51 of each group of disconnection settings can share one collector, so it is only necessary to detect the electrical signals at the first and last ends of the series resistors, which further simplifies the structure, reduces the number of collectors, and reduces the cost.

[0041] For illustration purposes, see Figure 4Taking two groups of detection wires 51 with circuit break settings sharing one collector as an example, the two groups of detection wires 51 with circuit break settings are respectively recorded as the first group and the second group. A first resistor 53 is connected between the two detection wires 51 of the first group, and a second resistor 54 is connected between the two detection wires 51 of the second group. The resistance values ​​of the first resistor 53 and the second resistor 54 are different, and one end of the first resistor 53 is connected in series with one end of the second resistor 54. The collector collects the resistance between the other end A of the first resistor 53 and the other end B of the second resistor 54. When the resistance value collected by the collector is within the first preset range, it indicates that the detection position corresponding to the two detection wires 51 of the first group has a leak; when the resistance value collected by the collector is within the second preset range, it indicates that the detection position corresponding to the two detection wires 51 of the second group has a leak; when the resistance value collected by the collector is within the third preset range, it indicates that the detection positions corresponding to the two detection wires 51 of the first group and the second group have a leak; wherein the first preset range is the range of the preset value within which the resistance value of the second resistor 54 fluctuates up and down, the second preset range is the range of the preset value within which the resistance value of the first resistor 53 fluctuates up and down, and the third preset range is the resistance range determined according to the resistance of the liquid, and the preset value can also be determined according to the resistance of the liquid. Taking the case where the resistance values ​​of the first resistor 53 and the second resistor 54 are both much larger than the resistance value of the liquid as an example, the preset value and the third preset range can be approximately taken as zero. When the resistance value collected by the collector is the resistance value of the second resistor 54, it indicates that the detection positions corresponding to the two detection wires 51 of the first group have leakage; when the resistance value collected by the collector is the resistance value of the first resistor 53, it indicates that the detection positions corresponding to the two detection wires 51 of the second group have leakage; when the resistance value collected by the collector is zero, it indicates that the detection positions corresponding to the two detection wires 51 of the first group and the second group have leakage. The judgment principle of sharing one collector for three or more groups of disconnected detection wires 51 is similar to the above, and the leakage position can be determined by the change of resistance value, which will not be described in detail.

[0042] Furthermore, the resistance value of each resistor is much greater than the resistance value of the liquid, so as to reduce the influence of the resistance of the liquid on the detection resistor. Specifically, the resistance value of each resistor can be increased or the resistance value of the liquid can be reduced by additives, etc., so that the resistance value of each resistor is much greater than the resistance value of the liquid. Specifically, the resistance value of each resistor can be set in a binary manner.

[0043] In some embodiments, a first connecting device 6 is provided at one end of each liquid conduit 2, and the first connecting device 6 is used to be detachably connected to a second connecting device 7 provided on a port on the manifold that cooperates with each liquid conduit 2 to connect each liquid conduit 2 with the corresponding port, and the first connecting device 6 can block the corresponding liquid conduit 2 when disconnected from the second connecting device 7, and the second connecting device 7 can block the corresponding port when disconnected from the first connecting device 6. That is, in normal operation, the first connecting device 6 is docked with the second connecting device 7, and the liquid conduit 2 is connected with the corresponding port. When a leakage occurs and needs maintenance, the first connecting device 6 is separated from the second connecting device 7, so that the liquid conduit 2 is separated from the corresponding port accordingly. In the separated state, the first connecting device 6 blocks the liquid conduit 2, and the second connecting device 7 blocks the corresponding port, thereby preventing leakage. As configured above, each liquid guide tube 2 and the liquid cooling body 1 connected to the liquid guide tube 2 are used as a disassembly unit. When any of the liquid guide tube 2 or the liquid cooling body 1 on the disassembly unit leaks, the disassembly unit can be disassembled from the liquid cooling system alone for repair, without the need to disassemble the entire liquid cooling system, thereby reducing maintenance costs and improving maintenance efficiency.

[0044] Specifically, the first detection device on each liquid cooling body 1 connected to the same first connection device 6 is connected in series with the second detection device on the liquid guide tube 2 connected to the first connection device 6, so that the liquid guide tube 2 connected to the first connection device 6 or each liquid cooling plate can be effectively detected when leaking, and the liquid guide tube 2 and the liquid cooling body 1 on the detection branch can be disassembled for maintenance. And for the leakage detection of each liquid cooling body 1 or liquid guide tube 2 of a disassembled unit, the electrical signal of the first detection band 3 and the second detection band 4 connected in series can be collected by a collector, and the structure is simple.

[0045] In some embodiments, the first connecting device 6 and the second connecting device 7 both include a connecting seat and a valve core, a flow channel is provided in the connecting seat, and a toggle head is provided on the connecting seat; the valve core is slidably arranged in the connecting seat, and the valve core is provided with a through hole and a groove, the toggle head on the connecting seat of the first connecting device 6 is used to insert into the groove of the valve core of the second connecting device 7, and the toggle head on the connecting seat of the second connecting device 7 is used to insert into the groove of the valve core of the first connecting device 6, the first connecting device 6 and the second connecting device 7 slide relative to each other so that the two through holes and the corresponding flow channels are synchronously opposite to each other for opening or staggered for blocking, and when the two toggle heads drive the two valve cores to slide to the blocking position, the two toggle heads are clamped with the corresponding connecting seats. Specifically, the two toggle heads drive the two valve cores to slide so that the through hole on the valve core on the first connecting device 6 and the flow channel on the connecting seat of the first connecting device 6 are relatively opened, and at the same time, the through hole on the valve core on the second connecting device 7 and the flow channel on the connecting seat of the second connecting device 7 are relatively opened, and the flow channel of the first connecting device 6 is opposite to the flow channel of the second connecting device 7, the first connecting device 6 and the second connecting device 7 are connected, and the toggle head on the first connecting device 6 is clamped with the connecting seat on the second connecting device 7, and the toggle head on the second connecting device 7 is clamped with the connecting seat on the first connecting device 6, so as to realize the connection between the first connecting device 6 and the second connecting device 7. When the first connecting device 6 and the second connecting device 7 slide in opposite directions relative to each other, the two toggle heads drive the two valve cores to slide so that the through hole on the valve core on the first connecting device 6 and the flow channel on the connecting seat of the first connecting device 6 are staggered and closed, and the through hole on the valve core on the second connecting device 7 and the flow channel on the connecting seat of the second connecting device 7 are staggered and closed, and the toggle head on the first connecting device 6 can be pulled out from the second connecting device 7, and the toggle head on the second connecting device 7 can be pulled out from the first connecting device 6, thereby realizing disassembly and separation.

[0046] In other embodiments, the first connecting device 6 and the second connecting device 7 may also adopt a conventional quick-release structure. Alternatively, the first connecting device 6 and the second connecting device 7 may both include a cut-off valve, and the two cut-off valves are detachably connected.
