Description

Liquid cooling system and server

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on January 19, 2024, with application number 202410084924.8 and invention name “A Liquid Cooling System and Server”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present invention relates to the field of heat dissipation technology, and more particularly to a liquid cooling system and a server. Background Art

[0003] As server power density increases, higher requirements are placed on heat dissipation. Liquid cooling offers higher heat exchange efficiency than air cooling, meeting these requirements. Currently, cold plate cooling is the predominant method for server liquid cooling. This method, also known as a liquid cold plate, exchanges heat with high-heat-generating components in the server and then connects to a heat exchanger via a liquid conduit, rapidly transferring heat to the server's exterior.

[0004] During server operation, the liquid cooling system may leak due to fatigue, vibration, or other reasons. If the server's electronic components come into contact with leaking high-pressure liquid, they are prone to short circuits and other malfunctions. Therefore, it is necessary to detect whether the liquid cooling device is leaking and to shut down the system in a timely manner when a leak is detected. Usually, a detection strip is set up 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, the above method makes it difficult to determine the location of the liquid cooling system leak, and the overall disassembly and repair cost is high and the efficiency is low.

[0012] Optionally, in the above liquid cooling system, each group of the detection wires with a circuit break setting is used to be connected to a different collector, so as to separately collect the electrical signals between each group of the detection wires.

[0013] Optionally, in the above-mentioned liquid cooling system, resistors with different resistance values ​​are connected between the two detection wires of at least two groups of open-circuit settings, and the resistors are connected in series, and the head and tail ends of each series-connected resistor are used to connect to the collector to collect the electrical signal between the head and tail ends.

[0014] Optionally, in the above liquid cooling system, any one of the two detection wires in each group is provided with a detection piece extending toward the other, and the detection pieces on the two detection wires in each group are arranged at intervals.

[0015] Optionally, in the above liquid cooling system, the detection pieces on each group of two detection wires are alternately distributed and a preset distance is left between them.

[0016] Optionally, in the above-mentioned liquid cooling system, a first connecting device is provided at one end of each of the liquid conduits, and the first connecting device is used to be detachably connected to a second connecting device on a port on the manifold that cooperates with each of the liquid conduits to connect the liquid conduits with the corresponding ports, and the first connecting device can block the corresponding liquid conduit when disconnected from the second connecting device, and the second connecting device can block the corresponding port when disconnected from the first connecting device.

[0017] The liquid cooling system provided by the present invention includes at least one liquid cooling body, at least one liquid conduit, a first detection zone provided on the liquid cooling body, and a second detection zone provided on the liquid conduit.

DETAILED DESCRIPTION

[0026] The embodiment of the present invention discloses a liquid cooling system and a server, which can realize leakage detection at different positions of the liquid cooling system, so that when a leakage is detected, a part of the liquid cooling system can be disassembled and repaired separately.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0028] The liquid cooling system provided in the present application includes at least one liquid cooling body and at least one liquid guide tube, which is connected to the corresponding liquid cooling body. The liquid cooling body is generally a liquid cooling plate. 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 be close to 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.

[0029] The liquid conduit in this application is used to drain high-temperature liquid from the liquid-cooling body and introduce low-temperature liquid. It should be noted that the liquid in the liquid-cooling body and the liquid conduit in this application can be either cooling water or a refrigerant. Cooling water includes, but is not limited to, water or a water mixture, such as antifreeze cooling water with ethylene glycol added, and refrigerant includes, but is not limited to, a refrigerant with fluorine added. The liquid conduit has an inlet and outlet channel for liquid circulation, allowing high-temperature liquid to flow out of the liquid-cooling body and low-temperature liquid to flow in. It is understood that the conduit can include either separate inlet and outlet pipes or an integrated multi-lumen tube with different lumens for liquid inlet and outlet. In this application, by providing a first detection zone and a second detection zone on the liquid-cooling body and the liquid conduit, respectively, and through their rational layout, leak detection in the liquid cooling system is achieved and local repair of the leak is facilitated. The following embodiments primarily describe the arrangement of the first and second detection zones and the connection relationship of the liquid conduit. Other structures of the liquid cooling system can be referred to in the prior art and will not be described here.

[0030] In one specific embodiment, referring to Figures 1 and 2 , the liquid cooling system provided by the present invention includes at least one liquid cooling body 1, at least one liquid conduit 2, a first detection zone 3 provided on the liquid cooling body 1, and a second detection zone 4 provided on the liquid conduit 2. The liquid conduit 2 is connected to the corresponding liquid cooling body 1, the first detection zone 3 is used to detect liquid leakage in the liquid cooling body 1, and the second detection zone 4 is used to detect liquid leakage in the liquid conduit 2. The second detection zone 4 provided on at least one liquid conduit 2 is connected in series with the first detection zone 3 provided on at least one liquid cooling body 1 connected to the liquid conduit 2. That is, at least one liquid-cooling tube 2 is connected to at least one liquid-cooling body 1, and the liquid-cooling tube 2 and at least one of the liquid-cooling bodies 1 it connects to serve as a detection branch. The first detection band 3 provided on the detection branch is connected in series with the second detection band 4. Thus, when a leak occurs in either the liquid-cooling tube 2 or the liquid-cooling body 1 on the detection branch, both can be effectively detected. Therefore, during maintenance, the liquid-cooling tube 2 and the liquid-cooling body 1 on the detection branch can be disassembled together for repair, or the liquid-cooling bodies 1 connected to the liquid-cooling tube 2 can be disassembled together as a disassembled unit for repair. Compared to each liquid-cooling tube 2 and each liquid-cooling body 1 being a separate detection branch, this simplifies the structure. In the corresponding control process, the amount of processed data is reduced.

[0031] The liquid cooling system provided by the present invention comprises a first detection zone 3 provided on the liquid cooling body 1 for detecting leakage, a second detection zone 4 provided on the liquid conduit 2 for detecting leakage, and the second detection zone 4 provided on at least one liquid conduit 2 being connected in series with the first detection zone 3 provided on at least one liquid cooling body 1 connected to that liquid conduit 2. This arrangement eliminates the need to disassemble the entire liquid cooling system for maintenance, improving maintenance efficiency and reducing maintenance costs. Furthermore, the connected liquid conduit 2 and liquid cooling body 1 do not need to be separately inspected as a detection branch, simplifying the structure and facilitating piping layout.

[0032] In some embodiments, the liquid guide tube 2 includes a separately arranged liquid inlet pipe and a liquid outlet pipe, and a second detection band 4 is respectively arranged on the liquid inlet pipe and the liquid outlet pipe, 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.

[0033] 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. The multiple liquid cooling bodies 1 can be connected in series or in parallel as needed. For high-heat-producing elements, multiple parallel liquid cooling bodies 1 can be set up, that is, the liquid conduit 2 supplies 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-producing elements, multiple series-connected liquid cooling bodies 1 can be set up, and the liquid flows through each series-connected liquid cooling body 1 in turn to take away the heat of the low-heat-producing element, thereby meeting the heat dissipation requirements while simplifying the pipeline structure and reducing energy consumption.

[0034] Furthermore, in the case where multiple liquid-cooling bodies 1 are connected to the same liquid conduit 2, each first detection zone 3 on the multiple liquid-cooling bodies 1 connected to the same liquid conduit 2 is connected in series with the second detection zone 4 on the liquid conduit 2. For the connected liquid-cooling bodies 1 and liquid conduits 2, they can be disassembled and maintained as a detection branch for ease of maintenance, requiring only disconnection and sealing at both ends of the detection branch. Therefore, each first detection zone 3 on the multiple liquid-cooling bodies 1 connected to at least one liquid conduit 2 is connected in series with the second detection zone 4 on the liquid conduit 2, that is, each first detection zone 3 on each liquid-cooling body 1 connected to at least one liquid conduit 2 is connected in series with the second detection zone 4 on the liquid conduit 2, thereby greatly simplifying the structure while facilitating individual maintenance.

[0035] In some embodiments, at least one liquid-cooling tube 2 is connected in parallel to multiple liquid-cooling bodies 1, and the first detection zones 3 provided on each parallel liquid-cooling body 1 are connected in series. That is, the multiple liquid-cooling bodies 1 connected by at least one liquid-cooling tube 2 are connected in parallel. The liquid-cooling tube 2 and the multiple liquid-cooling bodies 1 connected in parallel therewith constitute a detection branch, with each first detection zone 3 within the detection branch connected in series with each second detection zone 4. Each first detection zone 3 within the detection branch is connected in series with each second detection zone 4, facilitating connection between adjacent first detection zones 3 and / or second detection zones 4. Specifically, taking the example of two liquid-cooling bodies 1 connected in parallel on the liquid guide tube 2, for ease 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 guide tube 2 before connecting with the first liquid-cooling body is recorded as the first liquid guide portion, and the portion connected between the first liquid-cooling body and the second liquid-cooling body is recorded as the second liquid guide portion. Then, the second detection band 4 on the first liquid guide portion 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 guide portion, and the second detection band 4 on the second liquid guide portion 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 guide portion includes a separately provided first liquid inlet pipe and a first liquid outlet pipe, and the second liquid guide portion includes a separately provided second liquid inlet pipe and a second liquid outlet pipe, a second detection band 4 is provided on both. Specifically, the second detection zone 4 on the first liquid inlet pipe is first connected in series with the first detection zone 3 on the first liquid-cooled body, the first detection zone 3 on the first liquid-cooled body is then connected in series with the second detection zone 4 on the second liquid inlet pipe, the second detection zone 4 on the second liquid inlet pipe is then connected in series with the first detection zone 3 on the second liquid-cooled body, the first detection zone 3 on the second liquid-cooled body is connected in series with the second detection zone 4 on the second liquid outlet pipe, and the second detection zone 4 on the second liquid outlet pipe is connected in series with the second detection zone 4 on the first liquid outlet pipe. In other embodiments, the first detection zones 3 provided on each parallel liquid-cooled body 1 can also be connected in parallel and respectively connected in series with the second detection zone 4 on the liquid guide tube 2, so as to function as a detection branch for detection.

[0036] In some embodiments, the second detection strip 4 is provided with a first connector at the location corresponding to the connection between the liquid guide tube 2 and the liquid cooling body 1, and the second detection strip 4 is provided with a second connector that docks with the first connector. By providing the first connector and the second connector, the first detection strip 3 and the second detection strip 4 are laid on the corresponding locations during assembly, and the first connector and the second connector are used to connect them in series, which facilitates operation and does not require adjustment or damage to the structure of the first detection strip 3 and the second detection strip 4 during assembly.

[0037] In some embodiments, referring to FIG3 , the first detection band 3 and the second detection band 4 each include two detection wires 51 with a disconnected configuration. The two detection wires 51 of the first detection band 3 and the second detection band 4 connected in series are each connected in series to form a group. Each group of disconnected detection wires 51 is used to connect to a collector to collect electrical signals between the groups of detection wires 51. Disconnected configuration herein means that the two detection wires 51 are not connected. When a leak occurs in the liquid cooling system, 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. This allows the collector to directly or indirectly collect electrical signals such as the resistance between the two detection wires 51 or the current applied between the two wires. Changes in electrical signals such as resistance or current can be used to determine whether a leak has occurred in the corresponding liquid cooling body 1. In this embodiment, the series connection of the first detection band 3 and the second detection band 4 is achieved by connecting the two detection wires 51 in series, resulting in a simple structure and easy assembly. It is understood that each set of disconnected detection wires 51 is separately connected to a collector, including only two detection wires 51 connected in series as a group, or multiple sets of detection wires 51 connected in series are separately connected to a 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 separately provided, 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 separately provided first detection band 3 as a group, and the two detection wires 51 of the separately provided second detection band 4 as a group. Then, each set of detection wires 51 is separately connected to a collector, and the collector collects the electrical signals between each set of detection wires 51 to determine whether a leak occurs at the detection position corresponding to each set of detection wires 51.

[0038] In some embodiments, referring to FIG3 , each set of two detection wires 51 is provided with a detection strip 52 extending toward the other, and the detection strips 52 on the two detection wires 51 are spaced apart. It should be understood that spacing the detection strips 52 on the two detection wires 51 includes both the detection strips 52 on the two detection wires 51 not contacting each other and the detection strip 52 on any one detection wire 51 not contacting the other detection wire 51. During detection, a leakage problem can be detected when leaking liquid contacts both detection strips 52 simultaneously, or contacts both the detection strip 52 on one detection wire 51 and the other detection wire 51 simultaneously, or contacts both detection wires 51 simultaneously. The provision of the detection strips 52 increases the distance between the two detection wires 51 to expand the detection area, while also ensuring detection accuracy. Specifically, the smaller the distance between the detection strips 52 and the detection wires 51, the higher the detection accuracy.

[0039] Furthermore, the detection pieces 52 on the two detection wires 51 in each group are alternately arranged with a preset spacing between them. Specifically, the detection pieces 52 on each detection wire 51 are arranged in a comb-like pattern, and the width of the detection pieces 52 on the two detection wires 51 can be greater than, less than, or equal to half the spacing between the two detection wires 51. It should be noted that while the detection pieces 52 shown in FIG3 are rectangular, they can also be triangular, trapezoidal, L-shaped, or T-shaped. Any detection piece 52 can be configured to protrude from one detection wire 51 toward the other.

[0040] In some embodiments, each group of disconnected detection wires 51 is connected to a different collector to separately collect the electrical signals between each group of detection wires 51. By connecting each group of disconnected detection wires 51 to a corresponding collector, changes in the electrical signals collected by each collector can be used to directly determine whether a leak has occurred at the location of the corresponding group of detection wires 51, providing convenient judgment and rapid response.

[0041] In some embodiments, resistors of different resistances are connected between the two detection wires 51 in at least two groups of disconnected circuits. These resistors are connected in series, and the ends of each series resistor are connected to a collector to collect the electrical signal between them. It is understood that the electrical signal between the ends of each series resistor can be either the resistance value between the ends or the current value applied between them. In the above embodiment, the collector corresponding to each group of disconnected detection wires 51 detects the resistance between each group of disconnected detection wires 51 or the current applied between the two wires. When the two detection wires 51 in each disconnected group are connected due to liquid leakage, the resistance or current changes, thereby determining whether the corresponding detection branch has leaked. This embodiment differs from the above embodiment in that a separate collector is not required for each group of disconnected detection wires 51. Instead, each group of disconnected detection wires 51 can share a single collector. Therefore, only the electrical signal between the ends of each series resistor needs to be detected, further simplifying the structure, reducing the number of collectors, and lowering costs.

[0042] For ease of explanation, please refer to Figure 4. Taking two groups of detection wires 51 with open circuit settings sharing one collector as an example, the two groups of detection wires 51 with open circuit 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 a first preset range, it indicates that a leak has occurred at the detection locations corresponding to the two detection wires 51 of the first group; when the resistance value collected by the collector is within a second preset range, it indicates that a leak has occurred at the detection locations corresponding to the two detection wires 51 of the second group; when the resistance value collected by the collector is within a third preset range, it indicates that a leak has occurred at the detection locations corresponding to the two detection wires 51 of the first group and the second group, respectively. The first preset range is the range within which the resistance value of the second resistor 54 fluctuates above and below a preset value; the second preset range is the range within which the resistance value of the first resistor 53 fluctuates above and below a preset value; and the third preset range is a resistance range determined based on the resistance of the liquid. The preset value can also be determined based on the resistance of the liquid. For example, if the resistance values ​​of the first resistor 53 and the second resistor 54 are both much greater than the resistance value of the liquid, the preset value and the third preset range can be approximately zero. When the resistance value collected by the collector is the resistance value of the second resistor 54, it indicates that a leak has occurred at the detection locations corresponding to the two detection wires 51 of the first group; when the resistance value collected by the collector is the resistance value of the first resistor 53, it indicates that a leak has occurred at the detection locations corresponding to the two detection wires 51 of the second group; and when the resistance value collected by the collector is zero, it indicates that a leak has occurred at the detection locations corresponding to the two detection wires 51 of the first and second groups, respectively. The principle of determining when three or more groups of disconnected detection wires 51 share a single collector is similar to the above, and the leak location can be determined by changes in the resistance value. The details will not be repeated here.

[0043] Furthermore, the resistance of each resistor is significantly greater than the resistance of the liquid to reduce the effect of the liquid's resistance on the detection resistance. Specifically, the resistance of each resistor can be increased or reduced by using additives, etc. to make the resistance of each resistor significantly greater than the resistance of the liquid. Specifically, the resistance of each resistor can be set in a binary format.

[0044] In some embodiments, a first connecting device 6 is provided at one end of each liquid conduit 2. The first connecting device 6 is used to detachably connect 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. 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, under normal operating conditions, the first connecting device 6 and the second connecting device 7 are docked, and the liquid conduit 2 is connected to the corresponding port. When a leak occurs and maintenance is required, the first connecting device 6 and the second connecting device 7 are separated, thereby separating the liquid conduit 2 from the corresponding port. 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 set up above, each liquid guide tube 2 and the liquid cooling body 1 connected to the liquid guide tube 2 are regarded 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 maintenance. There is no need to disassemble the entire liquid cooling system, which reduces maintenance costs and improves maintenance efficiency.

[0045] Specifically, the first detection device on each liquid-cooling body 1 connected to the same first connecting device 6 is connected in series with the second detection device on the liquid conduit 2 connected to the first connecting device 6. This allows leaks in the liquid conduit 2 or each liquid cooling plate connected to the first connecting device 6 to be effectively detected. During maintenance, the liquid conduit 2 and the liquid-cooling body 1 on the detection branch can be removed together for repair. Furthermore, for leak detection of each liquid-cooling body 1 or liquid conduit 2 in a disassembled unit, a single collector can be used to collect the electrical signals of the first detection strip 3 and the second detection strip 4 connected in series, resulting in a simple structure.

[0046] 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 opposed to each other to open or staggered to block, and when the two toggle heads drive the two valve cores to slide to the blocking position, the two toggle heads are engaged 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 engaged with the connecting seat on the second connecting device 7, and the toggle head on the second connecting device 7 is engaged with the connecting seat on the first connecting device 6, thereby realizing 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 relative opposite directions, 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.

[0047] 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 shutoff valve, and the two shutoff valves may be detachably connected.

[0048] Based on the liquid cooling system provided in the above embodiments, the present invention further provides a server, which includes any one of the liquid cooling systems in the above embodiments. Since the server adopts the liquid cooling system in the above embodiments, the beneficial effects of the server can be referred to the above embodiments.

[0049] 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.
