[0042] Hereinafter, specific embodiments of the present application will be described in more detail with reference to the accompanying drawings. These drawings show representative embodiments of the present application and do not limit the present application.
[0043] With the rapid development of cloud computing, big data, artificial intelligence and other technologies, data centers need better heat dissipation. Figure 1 and Figure 3 As shown, the present application provides a segmented manifold 100, which is used in a liquid cooling system 200. The liquid cooling system 200 can adjust the temperature of the server in the cabinet 205 of the data center. The liquid cooling system 200 can cool down the main heating components in the server through the flow of heat exchange medium. The liquid cooling system 200 evenly distributes the heat exchange medium to the server to achieve efficient heat dissipation effect.
[0044] The liquid cooling system 200 includes a heat exchange unit, a segmented manifold 100 and a cold plate. The cold plate extends a hose to the rear interface of the server, and the hose is connected to the plug of the fluid connector. The segmented manifold 100 is composed of a manifold and a manifold. The segmented manifold 100 can evenly distribute the heat exchange medium from the heat exchange unit to the cold plates of each server in the cabinet 205. Through precise flow control and distribution, the segmented manifold 100 can enable the server to be sufficiently cooled.
[0045] The segmented manifold 100 can be maintained in segments, and the manual and blind insertion servers can be installed in the same liquid cooling cabinet. The segmented manifold 100 can also monitor a single node independently, avoiding the impact of a single node failure on the operation of other nodes in the entire cabinet 205, and can be flexibly expanded to meet the needs of cabinets 205 with different loads.
[0046] Specifically, the segmented manifold 100 includes a pipeline, which is used to communicate with the heat exchange unit. The pipeline can be constructed as a vertical pipe. The pipeline can be a square tube or a circular tube, which is arranged in sections. The segmented manifold 100 includes a main pipeline, in which a flow path is arranged. One main pipeline is used for water supply, and the other main pipeline is used for return water. The heat exchange medium can flow in the flow path. The main pipeline includes a first pipeline 103 and a second pipeline 104, and the first pipeline 103 and the second pipeline 104 are respectively connected to the heat exchange unit. The structures of the first pipeline 103 and the second pipeline 104 are similar. A main pipeline can be divided into multiple parts. The same main pipeline is divided into multiple pipelines. The same main section includes multiple branch main pipelines. The main pipeline can include a larger number of pipelines, such as three, four or more, which is not limited in this application. The first pipeline 103 and the second pipeline 104 are both used for water supply.
[0047] like Figure 2 As shown, the first pipeline 103 can be constructed as a vertical pipe. The first pipeline 103 can be a square tube or a circular tube, and is arranged in sections. The second pipeline 104 can be constructed as a vertical pipeline. The second pipeline 104 can be a square tube or a circular tube, and is arranged in sections. The heat exchange medium discharged from the heat exchange unit enters the first pipeline 103 and the second pipeline 104 respectively. The first pipeline 103 and the second pipeline 104 are arranged at intervals. The first pipeline 103 and the second pipeline 104 can be arranged at intervals along the axial direction of the main pipeline. The axial direction of the first pipeline 103 is parallel to the axial direction of the second pipeline 104. For the convenience of description, the axial direction of the main pipeline is used to replace the axial direction of the first pipeline 103 and the axial direction of the second pipeline 104.
[0048] Combination Figure 3 As shown, the segmented manifold 100 also includes a connection module 120, which connects the first pipeline 103 and the second pipeline 104. A main pipeline can be divided into multiple parts. The same main section is divided into multiple pipelines. Of course, the main pipeline can also include a larger number of pipelines, such as three, four or more, and adjacent pipelines are connected through the connection module 120, which is not limited in this application. The connection module 120 is used to connect each section of the main pipeline. The connection module 120 is configured as an openable and closable device. The connection module 120 can pass water normally when it is in the open state. The connection module 120 cannot pass water when it is in the closed state. The segmented manifold 100 also includes another main pipeline, which is also divided into multiple parts, and the other main pipeline is divided into multiple pipelines. A connection module is also provided between the multiple pipelines of the other main pipeline, and the multiple pipelines of the other main pipeline are all used for return water.
[0049] Specifically, the connection module 120 is located between the first pipeline 103 and the second pipeline 104. The opening and closing of the first pipeline 103 and the second pipeline 104 are controlled by the connection module 120. When a water leakage fault occurs in the first pipeline 103 or the second pipeline 104, the connection module 120 is closed to ensure that the normal operation of other branch pipelines is not affected. The connection module 120 is located between the first pipeline 103 and the second pipeline 104 along the axial direction of the main pipeline. The connection module 120 can open and close the flow path. The first pipeline 103 and the second pipeline 104 can be connected through the connection module 120. The heat exchange medium from the first pipeline 103 can flow to the server side through the connection module 120. The heat exchange medium from the second pipeline 104 can flow to the server side through the connection module 120.
[0050] The first pipeline 103 and the second pipeline 104 may also be separated by the connection module 120. When the first pipeline 103 and the second pipeline 104 are separated by the connection module 120, the heat exchange medium from the first pipeline 103 cannot flow into the second pipeline 104 through the connection module 120, and the heat exchange medium from the second pipeline 104 cannot flow into the first pipeline 103 through the connection module 120.
[0051] The main pipeline is arranged in sections, and the connecting module 120 is connected between each section of the pipeline. The connecting module 120 can divide the main pipeline into multiple sections. The connecting module 120 includes a first closed component 130, a second closed component 140 and a rotating component 150, and the rotating component 150 connects the first closed component 130 and the second closed component 140. The first closed component 130 is connected to the first pipeline 103, and the second closed component 140 is connected to the second pipeline 104. The first closed component 130 can be connected to the first pipeline 103 by threaded connection or other forms. The first closed component 130 is fixed to the first pipeline 103 and does not move relative to each other. The first closed component 130 is connected to the rotating component 150 by threaded connection or other forms. The second closed component 140 can be connected to the second pipeline 104 by threaded connection or other forms. The second closed component 140 is fixed to the second pipeline 104 and does not move relative to each other. The second closed component 140 is connected to the rotating component 150 by threaded connection or other forms.
[0052] The first sealing component 130 can be opened and closed to control the opening and closing of the flow path. The second sealing component 140 can be opened and closed to control the opening and closing of the flow path. The rotating component 150 is configured to be hollow. When the first sealing component 130 and the second sealing component 140 are both opened, the first pipeline 103 and the second pipeline 104 are connected. When the first sealing component 130 is closed, the first pipeline 103 and the second pipeline 104 are not connected. When the second sealing component 140 is closed, the first pipeline 103 and the second pipeline 104 are not connected.
[0053] In this way, the first pipeline 103 and the second pipeline 104 can each provide a heat exchange medium. When the first pipeline 103 and the second pipeline 104 do not need maintenance, the first pipeline 103 and the second pipeline 104 can both be connected to the cold plate. The first pipeline 103 and the second pipeline 104 can be repaired in sections. The maintenance of the first pipeline 103 will not affect the second pipeline 104. The maintenance of the second pipeline 104 will not affect the first pipeline 103. When the first pipeline 103 needs maintenance, the first sealing component 130 is closed, and the second pipeline 104 is connected to the cold plate. When the second pipeline 104 needs maintenance, the second sealing component 140 is closed, and the first pipeline 103 is connected to the cold plate.
[0054] The first pipeline 103 and the second pipeline 104 are opened and closed by the first sealing component 130 and / or the second sealing component 140 of the connection module 120. When a water leakage occurs in the first pipeline 103, the first sealing component 130 is closed to ensure that the normal operation of the second pipeline 104 is not affected. When a water leakage occurs in the second pipeline 104, the second sealing component 140 is closed to ensure that the normal operation of the second pipeline 104 is not affected.
[0055] According to the segmented manifold 100 of the present application, it is used in a liquid cooling system 200. The segmented manifold 100 includes a main line and a connecting module 120. The main line includes a first line 103 and a second line 104. A flow path is arranged in the main line. The connecting module 120 connects the first line 103 and the second line 104. The connecting module 120 includes a first closing component 130, a second closing component 140 and a rotating component 150. The first closing component 130 is connected to the first line 103. The first closing component 130 can be opened and closed to control the opening and closing of the flow path. The second closing component 140 is connected to the second line 104. The second closing component 140 can be opened and closed to control the opening and closing of the flow path. The rotating component 150 connects the first closing component 130 and the second closing component 140. In this way, the main pipe section is divided into different pipe sections through the connection module 120, and the water channels between different pipe sections can be fully enclosed through the connection module 120. The segmented manifold 100 is expandable, and different numbers of pipe sections can be expanded according to needs. The main pipe can be maintained in sections, and single-node single-pipe section maintenance can be achieved, and maintenance will not affect the operation of other nodes without stopping.
[0056] The structures of the first closed component 130 and the second closed component 140 are similar. The first closed component 130 and the second closed component 140 both include a main body and a switch member, and the switch member is located in the main body. The main body can be constructed to be hollow. A flow path is provided in the main body, and the flow path is opened or closed by opening and closing the switch member. The switch member can rotate in the flow path to open or close the flow path. The flow path in the open state is connected to the pipeline. The flow path in the closed state is closed. The switch member can rotate between an open position and a closed position. The switch member in the open position can make the flow path communicate with the pipeline. The switch member in the closed position can make the flow path and the pipeline disconnected. The heat exchange medium of the pipeline can flow to another pipeline through the switch member in the open position. The heat exchange medium of the pipeline cannot flow to another pipeline through the switch member in the closed position.
[0057] For example, the first closing component 130 includes a first main body and a first switch member, and the first switch member is located in the first main body. The first main body can be configured as a valve body. The first switch member is configured as a valve core. The valve core can be configured as a spherical valve core, and the waterway can be opened and closed by rotating the spherical valve core. The valve body is a shell that wraps the valve core. A sealing ring or other sealing member is provided in the valve body where the spherical valve core cooperates to ensure that no leakage occurs when the spherical valve core is in a closed state.
[0058] The first body is configured to be hollow. A first flow path is provided in the first body. The first switch member can rotate in the first flow path to open or close the first flow path. The first flow path in the open state is connected to the first pipeline 103. The first flow path in the closed state is closed. The first switch member can rotate between an open position and a closed position. The first switch member in the open position can make the first flow path connected to the first pipeline 103. The first switch member in the closed position can make the first flow path and the first pipeline 103 disconnected. The heat exchange medium of the first pipeline 103 can flow to the second pipeline 104 through the first switch member in the open position. The heat exchange medium of the first pipeline 103 cannot flow to the second pipeline 104 through the first switch member in the closed position.
[0059] The second closure assembly 140 includes a second body and a second switch member, and the second switch member is located in the second body. The second body can be configured as a valve body. The second switch member is configured as a valve core. The valve core can be configured as a spherical valve core, and the waterway can be opened and closed by rotating the spherical valve core. The valve body is a shell that wraps the valve core. A sealing ring or other sealing member is provided in the valve body where the spherical valve core cooperates to ensure that no leakage occurs when the spherical valve core is in a closed state.
[0060] The second body is configured to be hollow. A second flow path is provided in the second body. The second switch member can rotate in the second flow path to open or close the second flow path. The second flow path in the open state is connected to the second pipeline 104. The second flow path in the closed state is closed. The second switch member can rotate between an open position and a closed position. The second switch member in the open position can make the second flow path communicate with the second pipeline 104. The second switch member in the closed position can make the second flow path and the second pipeline 104 disconnected. The heat exchange medium of the second pipeline 104 can flow to the first pipeline 103 through the second switch member in the open position. The heat exchange medium of the second pipeline 104 cannot flow to the first pipeline 103 through the second switch member in the closed position. Any one of the first closing component 130 and the second closing component 140 can be closed to make the first pipeline 103 and the second pipeline 104 disconnected. The first closing component 130 can be closed to make the first pipeline 103 and the second pipeline 104 disconnected. When the second sealing component 140 is closed, the first pipeline 103 and the second pipeline 104 are disconnected.
[0061] In order to rotate the closing member, the first closing assembly 130 and the second closing assembly 140 also include an operating member, which is connected to the switch member. The operating member is located outside the body. The operating member can be configured as a handle. The operating member can drive the switch member to rotate.
[0062] The first closure assembly 130 also includes a first operating member 131, which is connected to the first switch member. The first operating member 131 is located outside the first body. The first operating member 131 is configured as a rod-shaped structure. A mechanism is provided between the first operating member 131 and the spherical valve core of the first switch member, and linkage can be achieved through the mechanism and the spherical valve core of the first switch member. The rotation of the first operating member 131 can drive the first switch member to rotate. When the first operating member 131 rotates, it will drive the spherical valve core of the first switch member to rotate, so as to achieve the function of controlling the opening and closing of the spherical valve core of the first switch member. The first operating member 131 can drive the first switch member to rotate between an open position and a closed position. The first switch member in the open position can be in a connected state and can pass water. The first switch member in the closed position is in a closed state.
[0063] As another optional implementation, the switch member can also be opened or closed by displacement. For example, the switch member can also be opened or closed by translational displacement of the first closure assembly. By rotating the first operating member 131 to translate the first switch member, the waterway can be circulated or blocked.
[0064] The second closure assembly 140 also includes a second operating member 141, which is connected to the second switch member. The second operating member 141 is located outside the second body. The second operating member 141 is configured as a rod-shaped structure. A mechanism is provided between the second operating member 141 and the spherical valve core of the second switch member, and linkage can be achieved through the mechanism and the spherical valve core of the second switch member. The rotation of the second operating member 141 can drive the second switch member to rotate. When the second operating member 141 rotates, the spherical valve core of the second switch member will be driven to rotate, so as to achieve the function of controlling the opening and closing of the spherical valve core of the second switch member. The second operating member 141 can drive the second switch member to rotate between an open position and a closed position. The second switch member located in the open position can be in a connected state and can pass water. The second switch member located in the closed position is in a closed state.
[0065] As another optional implementation, the switch member can also be opened or closed by displacement. For example, the switch member can also be opened or closed by translational displacement of the first closure component. By rotating the second operating member 141 to translate the first switch member, the waterway can be circulated or blocked.
[0066] As an optional implementation, the connection module 120 can be configured as a rotatable structure. In this way, the segmented manifold 100 can be maintained in sections and can also be set up in different areas. The same segmented manifold 100 can simultaneously adapt to the position requirements of the pipe interface of the hand-inserted server and the blind-inserted server. A part of the segmented manifold 100 can be set to the hand-inserted mode, and the other part can be set to the blind-inserted mode. The fluid connector of the blind-inserted part is directly opposite to the server interface position, and the fluid connector of the hand-inserted part is not directly opposite to the server interface position.
[0067] The rotating assembly 150 can rotate. The rotating assembly 150 can rotate around the axial direction of the main pipeline. The rotating assembly 150 can rotate around the axial direction of the main pipeline. The rotating assembly 150 is located between the first closed assembly 130 and the second closed assembly 140 along the axial direction of the main pipeline. The rotation of the rotating assembly 150 can respectively cause the positions of the first closed assembly 130 and the second closed assembly 140 to change relative to each other. The rotation of the first closed assembly 130 can drive the first pipeline 103 to rotate synchronously. The rotation of the second closed assembly 140 can drive the second pipeline 104 to rotate synchronously. The rotating assembly 150 can drive the first closed assembly 130 to rotate relative to the second closed assembly 140. The rotating assembly 150 can also drive the second closed assembly 140 to rotate relative to the first closed assembly 130.
[0068] Specifically, Figure 4, the rotating assembly 150 includes a first connecting member 151 and a second connecting member 152, and the first connecting member 151 and the second connecting member 152 can rotate relative to each other. The first connecting member 151 and the second connecting member 152 can both be configured as an annular structure. The first connecting member 151 can be configured as an outer annular ring. The first connecting member 151 can be configured as a rotatable part, and locking and unlocking can be achieved through a mechanism. The second connecting member 152 can be an inner annular ring. The second connecting member 152 can be configured as a fixing member. The interior of the second connecting member 152 can allow the heat exchange medium to pass through. The second connecting member 152 and the first pipeline 103 structure can be threadedly connected, and the range of rotation is guaranteed to be within the range of the threaded connection, and it will not loosen and fall due to rotation. When the second connecting member 152 needs to be disassembled, it can be directly disassembled.
