Description

Liquid cooling system and server

Technical Field

[0002] The present application relates to the field of heat dissipation technology, and more specifically, 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, and other factors. Exposure to leaking high-pressure liquid can cause short circuits and other malfunctions in the server's electronic components. Therefore, leak detection is essential, and if detected, the system must be shut down and repaired immediately. However, detecting a leak typically requires disassembling the entire cooling system for repair, resulting in high repair costs and low efficiency.

DETAILED DESCRIPTION

[0025] An embodiment of the present application discloses a liquid cooling system and a server. When a liquid cooling body or a liquid guide tube of the liquid cooling system leaks, a group of connected liquid guide tubes and the liquid cooling body corresponding to the leaking liquid guide tube or the liquid cooling body are removed separately as a maintenance unit, without the need to disassemble the entire liquid cooling system, thereby reducing costs and improving efficiency.

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

[0027] The liquid cooling system provided in the present application includes a liquid cooling body, a first liquid conduit and a manifold. 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 indirectly generate heat by absorbing heat from elements that generate heat themselves. At least one side of the liquid cooling body is a heating surface for being placed 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 manifold in the present application may be a multi-pass structure, which includes a manifold and a manifold. It is understood that the manifold and the manifold may be separately provided structures or integrated into one structure.

[0029] The first liquid conduit in the present application is connected at one end to the corresponding liquid cooling body, and at the other end to different ports of the manifold. The first liquid conduit is used to guide the high-temperature liquid out of the liquid cooling body and introduce the low-temperature liquid into the liquid cooling body. It should be noted that the liquid in the liquid cooling body and the liquid conduit 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 added ethylene glycol, and the refrigerant includes but is not limited to refrigerant with added fluorine. The first liquid conduit has an inlet channel and an outlet channel for liquid circulation, so that the high-temperature liquid in the liquid cooling body can flow out and the low-temperature liquid can flow in. It can be understood that it can include a separately arranged inlet pipe and outlet pipe, or an integrated multi-lumen tube, and different lumens of the multi-lumen tube are used for the entry and exit of liquid.

[0030] In this application, in response to possible leakage of the liquid cooling body and the liquid guide tube, corresponding structures are provided to facilitate the repair of the leaking location separately. In the following embodiments, the above structures are mainly described. Other structures of the liquid cooling system can refer to the existing technology and will not be repeated here.

[0031] In a specific embodiment, referring to Figures 1 and 2, the liquid cooling system provided by the present application includes a manifold 2, multiple liquid cooling bodies 1, and multiple first liquid guide tubes 3. Each liquid cooling body 1 is used to exchange heat with a heating element, one end of each first liquid guide tube 3 is connected to at least one corresponding liquid cooling body 1, and the other end of each first liquid guide tube 3 is connected to a different port of the manifold 2 via a corresponding cut-off assembly 4. Unlike conventional first guide vane ducts that are directly connected to corresponding ports of the manifold 2, the present application provides a cut-off assembly 4 between the two. The cut-off assembly 4 includes a first connecting device 41 and a second connecting device 42 that can be detached from each other. The first connecting device 41 is provided at the pipe mouth of the first liquid guide tube 3 and blocks the corresponding first liquid guide tube 3 when detached from the second connecting device 42. The second connecting device 42 is provided at the port and blocks the corresponding port when detached from the first connecting device 41. That is, under normal operating conditions, the first connecting device 41 is docked with the second connecting device 42, and the first liquid guide tube 3 is connected to the corresponding port. When a leak occurs and maintenance is required, the disconnect assembly 4 is disconnected, that is, the first connecting device 41 is separated from the second connecting device 42, thereby separating the first liquid conduit 3 from the corresponding port. In this separated state, the first connecting device 41 blocks the first liquid conduit 3, and the second connecting device 42 blocks the corresponding port, thereby preventing leakage.

[0032] In the liquid cooling system provided herein, each first liquid conduit 3 is connected to the corresponding port of the manifold 2 via a cutoff assembly 4. If any first liquid conduit 3 leaks or any liquid cooling body 1 leaks, if any first liquid conduit 3 leaks, the first connecting device 41 and the second connecting device 42 in the cutoff assembly 4 connecting the leaking first liquid conduit 3 to the corresponding port are removed and separated. If any liquid cooling body 1 leaks, the first connecting device 41 and the second connecting device 42 in the cutoff assembly 4 connecting the first liquid conduit 3 connected to the liquid cooling body 1 are removed and separated. After separation, the first connecting device 41 blocks the opening of the first liquid conduit 3 to prevent leakage of liquid from the first liquid conduit 3 and the first liquid cooling body 1 connected thereto. Simultaneously, the second connecting device 42 blocks the corresponding port of the manifold 2 to prevent leakage of liquid from the manifold 2. In summary, the liquid cooling system provided in the present application can, when a leak occurs, remove the connected first liquid guide pipe 3 and the liquid cooling body 1 corresponding to the leak location as a maintenance unit from the liquid cooling system for maintenance, without the need to disassemble the entire liquid cooling system, thereby reducing maintenance costs and improving maintenance efficiency.

[0033] In some embodiments, the first liquid conduit 3 comprises a separately provided first liquid inlet and first liquid outlet. These first liquid inlet and first liquid outlet are connected to the first outlet and first inlet / outlet of the manifold 2, respectively, via corresponding cutoff assemblies 4. During disassembly, both the cutoff assemblies 4 between the first liquid inlet and the first outlet, and between the first liquid outlet and the first inlet, are disconnected. In other embodiments, the first liquid conduit 3 is a multi-lumen tube. A set of cutoff assemblies 4 may be provided between the multi-lumen tube and the corresponding ports.

[0034] In some embodiments, at least one row of liquid-cooling bodies 1 is arranged along the arrangement direction of the ports of the manifold 2. Each liquid-cooling body 1 in the at least one row is connected to a different port of the manifold 2 via a corresponding first liquid conduit 3. Arranging multiple liquid-cooling bodies 1 along the arrangement direction of the ports helps shorten the length of the first liquid conduits 3 and facilitates the layout of the first liquid conduits 3. For example, arranging at least some of the first liquid conduits 3 in parallel can reduce the mutual influence of the layout of the first liquid conduits 3.

[0035] In some embodiments, multiple rows of liquid-cooling bodies 1 are provided along the arrangement direction of the ports of the manifold 2. This arrangement improves heat dissipation efficiency. The correspondence between each liquid-cooling body 1 and the first liquid conduit 3 can be configured as needed. It should be noted that the term "multiple rows" in this application refers to two or more rows.

[0036] Furthermore, each row of liquid-cooling bodies 1 is located on the same side of the manifold 2. This arrangement facilitates the layout of the first liquid conduit 3. Furthermore, even if a leak occurs, the potential leak location is relatively small, making repair easier. In other embodiments, the liquid-cooling bodies 1 can be located on different sides of the manifold 2, depending on the layout requirements of the heating elements.

[0037] In some embodiments, the liquid-cooling bodies 1 in at least two columns are distributed side by side. The side-by-side distribution can be specifically perpendicular to the arrangement direction of the ports of the manifold 2, and the liquid-cooling bodies 1 in at least two columns are distributed in sequence in a collinear manner. Taking Figure 2 as an example, the two columns of liquid-cooling bodies 1 from the left in Figure 2 are parallel to the lines connecting the liquid-cooling bodies 1 from top to bottom. When three columns of liquid-cooling bodies 1 are provided, the corresponding liquid-cooling bodies 1 in the three columns of liquid-cooling bodies 1 are collinear and parallel to each other from top to bottom. In this embodiment, the liquid-cooling bodies 1 in at least two columns are distributed in an array of multiple rows and columns as a whole. The array distribution structure is compact and has high space utilization. Moreover, the possible leakage areas corresponding to the liquid-cooling bodies 1 distributed in the array are regular, with little relative shielding and influence, or even no mutual shielding relationship, which is convenient for separate maintenance.

[0038] In some embodiments, the liquid-cooling bodies 1 arranged side by side are connected in parallel via the second liquid conduit 5. That is, the liquid-cooling bodies 1 arranged side by side are connected in parallel to the corresponding first liquid conduit 3 via the second liquid conduit 5. The first liquid conduit 3 and the liquid-cooling bodies 1 connected in parallel to the first liquid conduit 3 and the second liquid conduits 2 are used as a detection unit. When at least one of the first liquid conduit 3, the liquid-cooling bodies 1 connected in parallel to the first liquid conduit 3, and the second liquid conduits 5 connected in parallel to the liquid-cooling bodies 1 leaks, the maintenance unit is disassembled as a whole. That is, the disconnection assembly 4 between the first liquid conduit 3 and the corresponding port is disconnected. For high-heat-generating components, multiple liquid-cooling bodies 1 can be set up in parallel, that is, the first liquid conduit 3 supplies cooling to each parallel liquid-cooling body 1 directly or indirectly through the second liquid conduit 5, so that each liquid-cooling body 1 can provide a higher heat exchange efficiency.

[0039] In some embodiments, at least one row of liquid-cooling bodies 1 is connected in series via a third liquid conduit 6, and the two liquid-cooling bodies 1 at the head and tail ends are connected to corresponding ports via the liquid inlet pipe 31 and liquid outlet pipe 32 of the first liquid conduit 3. Specifically, the first liquid conduit 3 connected to each series of liquid-cooling bodies 1 includes separate liquid inlet pipes 31 and liquid outlet pipes 32. The liquid inlet pipe 31 is connected to the corresponding port via a cutoff assembly 4, and the liquid outlet pipe 32 is connected to the corresponding port via a cutoff assembly 4. The liquid inlet pipe 31, liquid outlet pipe 32, third liquid conduit 6, and each liquid-cooling body 1 connected in series between the liquid inlet pipe 31 and the liquid outlet pipe 32 serve as a detection unit. If at least one of the liquid inlet pipe 31, liquid outlet pipe 32, each liquid-cooling body 1 connected in series between the liquid inlet pipe 31 and the liquid outlet pipe 32, or the third liquid conduit 6 connected in series to each liquid-cooling body 1 leaks, the entire repair unit is disassembled. Specifically, the cutoff assembly 4 between the liquid inlet pipe 31 and the corresponding port and the cutoff assembly 4 between the liquid outlet pipe 32 and the corresponding port are disconnected. For low-heat-generating components, multiple liquid-cooling bodies 1 connected in series can be set up, and liquid flows through each liquid-cooling body 1 in series in turn to take away the heat of the low-heat-generating components, thereby meeting the heat dissipation requirements while simplifying the pipeline structure and reducing energy consumption.

[0040] In some embodiments, multiple rows and columns of liquid-cooling bodies 1 are arranged on the same side of the manifold 2, and at least one column of liquid-cooling bodies 1 is connected in series via a third liquid conduit 6. The liquid-cooling bodies 1 arranged side by side in at least two columns of liquid-cooling bodies 1 are connected in parallel via a second liquid conduit 5. This arrangement creates a gridded heat dissipation area, fully utilizing the high heat dissipation efficiency of the parallel-arranged liquid-cooling bodies 1 and the low energy consumption of the series-arranged liquid-cooling bodies 1, thereby optimizing the overall performance of the liquid cooling system. Furthermore, the layout of the first, second, and third liquid conduits 3, 5, and 6 is convenient, such as with the second, third, and first liquid conduits 3 arranged in parallel, the third, and finally the third liquid conduits 6, respectively.

[0041] To facilitate the arrangement of the first liquid guide pipe 3, taking one row of liquid-cooling bodies 1 connected in series and the remaining rows of liquid-cooling bodies 1 arranged in parallel, each first liquid guide pipe 3 includes a liquid inlet pipe 31 and a liquid outlet pipe 32 as an example, the liquid inlet pipe 31 connected to the first row of liquid-cooling bodies 1 arranged in parallel is connected to the outlet of the first row on the manifold 2, and the liquid inlet pipes 31 connected to the remaining rows of liquid-cooling bodies 1 arranged in parallel are connected to the outlets of each row of the manifold 2 in turn; the first row of liquid-cooling bodies 1 in a row of liquid-cooling bodies 1 in series is connected to the liquid outlet pipe 32 and is connected to the inlet of the first row on the manifold 2, and the last row of liquid-cooling bodies 1 in a row of liquid-cooling bodies 1 in series is connected to the liquid inlet pipe 31 and is connected to the inlet of the last row on the manifold 2; the liquid outlet pipe 32 connected to the first row of liquid-cooling bodies 1 arranged in parallel is connected to the inlet of the second row on the manifold 2, and the liquid outlet pipes 32 connected to the remaining rows of liquid-cooling bodies 1 arranged in parallel are connected to the inlet of each row of the manifold 2 in turn. As configured above, the first liquid cooling pipe has a short layout line, is less likely to be entangled, and reduces the mutual influence between the lines.

[0042] In some embodiments, multiple liquid-cooling bodies 1 connected in parallel are used to exchange heat with the graphics processor, while multiple liquid-cooling bodies 1 connected in series are used to exchange heat with switching components. The graphics processor generates a lot of heat, and cooling it with multiple liquid-cooling bodies 1 connected in parallel achieves high heat dissipation efficiency, ensuring reliable operation of the graphics processor. Switching components generate less heat, and cooling them with multiple liquid-cooling bodies 1 connected in series meets heat dissipation requirements while reducing energy consumption.

[0043] In some embodiments, the liquid cooling system further includes a detection device 7 for detecting leakage of the liquid cooling body 1 and / or the first liquid guide tube 3. When the detection device 7 detects leakage, the first connecting device 41 and the second connecting device 42 are disassembled. By setting the detection device 7, when no leakage is detected, the first connecting device 41 and the second connecting device 42 remain connected, and when leakage is detected, the corresponding first connecting device 41 and the second connecting device 42 are disassembled and separated to repair the separated detection unit separately. The above arrangement facilitates timely detection of leakage and taking corresponding measures. The detection device 7 can specifically be a conventional detection structure such as a liquid sensor or a detection tape for detecting leakage, which is not specifically limited here. In other embodiments, visual inspection can also be used to disassemble the first connecting device 41 and the second connecting device 42 at the corresponding position when leakage is observed.

[0044] In some embodiments, referring to FIG. 3 , the detection device 7 includes two detection wires 71 in an open circuit configuration. A detection piece 72 extending toward the other and spaced apart is provided on one of the two detection wires 71. It will be understood that the spacing of the detection pieces 72 includes both the detection pieces 72 on the two detection wires 71 not contacting each other and the detection piece 72 on any detection wire 71 not contacting the other detection wire 71. During detection, a leakage problem can be detected when leaking liquid simultaneously contacts both detection pieces 72, or simultaneously contacts the detection piece 72 on one detection wire 51 and the other detection wire 71, or simultaneously contacts both detection wires 71. The provision of the detection piece 72 increases the distance between the two detection wires 71 to expand the detection area, while also ensuring detection accuracy. Specifically, the smaller the distance between the detection piece 72 and the detection wire 71, the higher the detection accuracy.

[0045] Furthermore, the detection pieces 72 on the two detection wires 71 are alternately arranged with a preset spacing between them. Specifically, the detection pieces 72 on each detection wire 71 are arranged in a comb-like pattern, and the width of the detection pieces 72 on the two detection wires 71 can be greater than, less than, or equal to half the spacing between the two detection wires 71. It should be noted that while the detection pieces 72 shown in FIG3 are rectangular, they can also be triangular, trapezoidal, L-shaped, or T-shaped. Any detection piece 72 can be configured such that one detection wire 71 protrudes toward the other detection wire 71.

[0046] In some embodiments, the first connecting device 41 and the second connecting device 42 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 provided 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 41 is used to insert into the groove of the valve core of the second connecting device 42, and the toggle head on the connecting seat of the second connecting device 42 is used to insert into the groove of the valve core of the first connecting device 41, the first connecting device 41 and the second connecting device 42 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 41 and the flow channel on the connecting seat of the first connecting device 41 are relatively opened, and at the same time, the through hole on the valve core on the second connecting device 42 and the flow channel on the connecting seat of the second connecting device 42 are relatively opened, and the flow channel of the first connecting device 41 is opposite to the flow channel of the second connecting device 42, the first connecting device 41 and the second connecting device 42 are connected, and the toggle head on the first connecting device 41 is engaged with the connecting seat on the second connecting device 42, and the toggle head on the second connecting device 42 is engaged with the connecting seat on the first connecting device 41, thereby realizing the connection between the first connecting device 41 and the second connecting device 42. When the first connecting device 41 and the second connecting device 42 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 of the first connecting device 41 and the flow channel on the connecting seat of the first connecting device 41 are staggered and closed, and the through hole on the valve core of the second connecting device 42 and the flow channel on the connecting seat of the second connecting device 42 are staggered and closed, and the toggle head on the first connecting device 41 can be pulled out of the second connecting device 42, and the toggle head on the second connecting device 42 can be pulled out of the first connecting device 41, thereby achieving disassembly and separation. In other embodiments, the valve core can also be rotatably mounted on the connecting seat, and the toggle head drives the valve core to rotate to open or close it.

[0047] In other embodiments, the first connecting device 41 and the second connecting device 42 may also employ conventional quick-release structures. Alternatively, the first connecting device 41 and the second connecting device 42 may both include shutoff valves, and the shutoff valves may be detachably connected, such as directly or via a pipeline. Alternatively, the shutoff valves may be integrated into a quick-release connector, enabling both rapid assembly and disassembly and a separate seal after disassembly.

[0048] Based on the liquid cooling system provided in the above embodiments, the present application 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.
