Description

Technical Field

[0001] This invention relates to the field of communication equipment technology, and in particular to a blind insertion mechanism and a server rack. Background Technology

[0002] With the rapid development of 5G services, AI technology, and computing networks, and the high importance the country attaches to the development of data centers, green and high-quality development of new infrastructure has become the primary direction for data center development. Therefore, more energy-efficient liquid cooling technology is showing increasing advantages and broader application prospects in the data center field, with cold plate liquid cooling being one of the main directions of liquid cooling technology.

[0003] Cold plate liquid cooling is a cooling method that connects the server's internal chips, GPU, and other heat-generating components through pipes filled with coolant. It adds heat exchange devices to the heat-generating components so that the coolant absorbs and carries away the heat. Compared to traditional air-cooled servers, cold plate liquid cooling is more targeted in heat dissipation.

[0004] Currently, there is no unified standard for cold plate liquid-cooled cabinets and servers. Cabinets and servers from different manufacturers are incompatible with each other, and the size, position, and model of various interfaces are not standardized. It is impossible to decouple the server and liquid-cooled cabinet, and they often need to be used together, which makes it difficult to flexibly adapt to actual application conditions. Summary of the Invention

[0040] Figure 1 This is a schematic diagram of the blind insertion mechanism provided by the present invention, as shown below. Figure 1 As shown, the present invention provides a blind insertion mechanism, including a main frame 1, at least one clamping member 2, an elastic member 3, and a first quick-connect member 4;

[0041] One end of the elastic member 3 is connected to the side of the main frame 1, and the other end is connected to the clamping member 2. The clamping member 2 extends from the front end to the rear end of the main frame 1. The first quick connector is located at the rear end of the clamping member 2. The elastic member 3 and the clamping member 2 are used to cooperate in clamping and inserting servers of different sizes into the blind insertion mechanism. The first quick connector 4 is used to connect with the second quick connector 5 on the server.

[0042] Specifically, the main frame 1 can be made of metal and is rectangular in shape. The elastic element 3 can be made of springs, and the clamping element 2 can be made of long strip-shaped clamps. Each clamping element 2 corresponds to multiple elastic elements 3. The front end of the main frame refers to the end into which the server is inserted, and the rear end of the main frame refers to the end opposite to the front end.

[0043] Liquid-cooled servers 8 from different manufacturers and models have varying structural dimensions. Currently, the mainstream server sizes are 19 inches and 21 inches, with heights including 1U, 2U, and 4U. The height of the main frame 1 corresponds to the height of the server. If there is one clamping component 2, the distance between the clamping component 2 and the main frame 1 is less than the width of the server. If there are two clamping components 2, the distance between the clamping components 2 is less than the width of the server, so that the clamping components 2 can hold the server after it is inserted into the blind-plug mechanism.

[0044] When the server is inserted into the blind insertion mechanism, the server squeezes the clamping member 2, causing the clamping member 2 to compress the elastic member 3. After the elastic member 3 is deformed by the pressure, it applies an elastic force to the clamping member 2. Under the elastic force of the elastic member 3, the clamping member 2 clamps the server, improving the stability of the server.

[0045] Optionally, the present invention provides two clamping members 2 and at least two elastic members 3. The two clamping members 2 are arranged opposite to each other and spaced apart. One clamping member 2 is connected to one side of the main frame 1 through one elastic member 3, and the other clamping member 2 is connected to the other side of the main frame 1 through another elastic member 3. A clamping space for clamping servers of different sizes is formed between the two clamping members 3.

[0046] The first quick connector 4 is a female quick connector, and the second quick connector 5 is a male quick connector. The first quick connector 4 is fixed on the clamping member 2 and moves with the clamping member 2 to achieve quick connection with the second quick connector 5 on the server, thus enabling automatic adjustment of the quick connector position for servers of different sizes.

[0047] Optionally, the blind insertion mechanism further includes a bracket connected to the clamping member 2, the first quick-connect member 4 being fixed to the bracket, the bracket including at least one fixing plate with a fixing hole, one end of the fixing plate being fixed to the clamping member, and the first quick-connect member passing through the fixing hole.

[0048] Specifically, such as Figure 1 As shown, the bracket includes two opposing fixing plates, each fixing plate having a fixing hole. The first quick-connect piece passes through the two fixing holes for fixing. The two fixing plates are perpendicular to the clamping member 2. The fixing plates can be integrally formed with the clamping member 2 or welded to the clamping member 2 by glue or welding.

[0049] The distance between the liquid inlet / outlet (the second quick connector is installed on the liquid inlet / outlet) and the server frame is fixed for servers of different manufacturers and models. When clamping servers of different sizes, the second quick connector moves with the clamping component while ensuring that the distance between the liquid inlet / outlet and the clamping component remains fixed. Therefore, it is possible to ensure blind insertion of the first and second quick connectors while clamping servers of different sizes.

[0050] It is understandable that this invention enhances rack compatibility and forms a complete system by adding a blind-plug frame that can automatically expand and adjust according to the server size, while also enabling the blind-plug interface (quick connector female) to automatically adjust to servers of different sizes.

[0051] Based on the above embodiments, as an optional embodiment,

[0052] The bottom surface of the main frame 1 is provided with a snap-fit ​​part 6 that mates with the server, so as to position the server in the left-right direction within the blind insertion mechanism. (Refer to...) Figure 1 The left and right directions refer to the left and right directions shown in the diagram, which are perpendicular to the insertion direction of the server. There are two locking parts 6, parallel to the clamping components, which position the server at both ends of the insertion direction.

[0053] The lower surface of the server has a part corresponding to the card connector 6, which cooperates with the card connector to be used for left and right positioning of the server, so as to realize precise blind insertion of the server.

[0054] It is understood that by setting the card connector 6, the present invention can achieve left and right directional positioning and precise blind insertion of the server.

[0055] Based on the above embodiments, as an optional embodiment, the snap-fit ​​part 6 is a slide rail, parallel to the clamping member 2, extending from the front end to the rear end of the main frame 1, and the slide rail is used to cooperate with the protrusion on the bottom of the server.

[0056] In another embodiment, the latching part is a raised slide bar, and the lower surface of the server has a groove at the corresponding position. The groove cooperates with the raised slide bar to realize the left and right positioning of the server and precise blind insertion.

[0057] Understandably, a rail for positioning the server is installed on the blind insertion mechanism below the clamping member 2 to facilitate server mounting and to guide the second quick connector 5 on the server to be blindly inserted into the first quick connector 4 on the blind insertion mechanism.

[0058] Based on the above embodiments, as an optional embodiment, it further includes an inlet branch pipe 12 and an outlet branch pipe 13, wherein the first quick-connect fitting 4 on one of the clamping members 2 is connected to the inlet branch pipe 12, and the first quick-connect fitting 4 on the other clamping member 2 is connected to the outlet branch pipe 13. The inlet branch pipe 12 and the outlet branch pipe 13 are used to realize the liquid inlet and outlet of the liquid-cooled server, so that the coolant can enter and exit the liquid-cooled server to cool it down.

[0059] Based on the above embodiments, as an optional embodiment, the blind insertion mechanism provided by the present invention further includes a first detection switch circuit for detecting the connection between the first quick connector 4 and the second quick connector 5.

[0060] The first detection switch circuit is composed of a detection switch sensor, which is located at the first quick connector 4 and is used to detect the connection between the first quick connector 4 and the second quick connector 5.

[0061] Optionally, the first detection switch circuit also includes an indicator light, which is connected in series with the first detection switch circuit. If the first quick connector 4 and the second quick connector 5 are correctly connected, the first detection switch circuit is closed, and the indicator light lights up, indicating that the server has been correctly installed, serving as a reminder and maintenance function.

[0062] It is understood that the present invention uses detection elements at the interface to form a detection circuit to detect whether each interface of the server is correctly connected.

[0063] The server rack provided by the present invention is described below. The server rack described below can be referred to in correspondence with the blind insertion mechanism described above.

[0064] Figure 2 This is a partial structural diagram of the server rack provided by the present invention, as shown below. Figure 2 As shown, the present invention also provides a server rack, including the aforementioned blind insertion mechanism, and further including a rack body 7 and a liquid cooling circulation system;

[0065] The cabinet 7 is equipped with multiple blind insertion mechanisms to accommodate the server, and the server includes at least a liquid-cooled server 8;

[0066] The liquid cooling circulation system is fixed to the cabinet 7, and the first quick connector 4 and the second quick connector 5 are plugged in and connected to each other so that the liquid cooling circulation system is circulated and connected with the liquid cooling path in the liquid cooling server 8.

[0067] The liquid-cooled server 8 has a liquid inlet and a liquid outlet at its rear end. The liquid inlet and outlet are each connected to a second quick-connect fitting 5. After the liquid-cooled server 8 is inserted into the blind-fitting mechanism, the liquid inlet and outlet are connected to the liquid cooling circulation system via the second quick-connect fitting 5 and the first quick-connect fitting 4, respectively. The liquid cooling circulation system is used to cool the liquid-cooled server 8.

[0068] Before the liquid-cooled server 8 is racked, the blind-insertion mechanism is first installed inside the cabinet 7 using bolts and fasteners. When servers of different sizes are racked, the elastic element 3 is compressed, but the amount of compression varies, ensuring that the clamping element 2 always holds the server firmly. Simultaneously, there is a slide rail below the blind-insertion mechanism to fix the server's position. The lower part of the server has a protrusion that mates with the groove in the slide rail, achieving left-right positioning of the server and enabling precise blind insertion. The other side of the quick-connect female on the blind-insertion mechanism is connected to the liquid cooling circulation system via a flexible hose. The movable clamping element 2 and the slide rail align the blind-insertion connectors. The distance between the liquid inlet / outlet and the server frame is fixed for servers of different manufacturers and models, and the protrusion at the bottom mates with the groove in the slide rail, enabling racking and blind insertion of the server. This greatly increases the compatibility and flexibility of the cabinet, adapting to various servers that meet different requirements and achieving decoupling between the server and the cabinet.

[0069] It is understood that by setting up a blind insertion mechanism and a liquid cooling circulation system, the present invention can simultaneously mount servers of different sizes without adjusting the column spacing or installing fixing strips of different sizes.

[0070] Figure 3 This is a schematic diagram of the backend structure of the server mechanism provided by the present invention, as shown below. Figure 3 As shown, based on the above embodiments, as an optional embodiment, the liquid cooling circulation system includes a liquid distribution device 9, a liquid inlet main pipe 10, a liquid outlet main pipe 11, a liquid inlet branch pipe 12, and a liquid outlet branch pipe 13;

[0071] The cold liquid distribution device 9 is connected to the inlet main pipe 10 and the outlet main pipe 11; the inlet branch pipe 12 is connected to the inlet main pipe 10 through the first quick connector 4, and the outlet branch pipe 13 is connected to the outlet main pipe 11 through the first quick connector 4.

[0072] The coolant distribution device 9 is used to supply low-temperature coolant to the server through the main inlet pipe 10 and the branch inlet pipe 12, and to recover high-temperature coolant from inside the server through the main outlet pipe 11 and the branch outlet pipe 13, and to cool the high-temperature coolant.

[0073] The coolant is supplied and recycled in the cabinet 7 and the liquid-cooled server 8 through the inlet manifold 10 and the outlet manifold 11. The lower end of the manifold has a coolant inlet and an outlet, which are connected to the coolant distribution device 9. The coolant distribution device 9 can be a centralized device located outside the cabinet or a distributed device integrated inside the cabinet.

[0074] Cabinet 7 provides cooling and power to the liquid-cooled server 8. The server has a pre-installed liquid inlet 14, liquid outlet 15, and power interface. Before mounting the liquid-cooled server 8, the second quick-connect fitting 5 is installed on the liquid inlet 14 and liquid outlet 15. The blind-fitting mechanism on cabinet 7 is pre-installed with the first quick-connect fitting 4. The other side of the first quick-connect fitting 4 is connected to the main liquid inlet pipe 10 and the main liquid outlet pipe 11 via the liquid inlet branch pipe 12 and the liquid outlet branch pipe 13. Coolant circulation process: The low-temperature coolant flowing from the coolant distribution device 9 enters the liquid cooling main pipe through the inlet at the lower end of the main liquid inlet pipe 10. The coolant flows through the first quick-connect fitting 4, the second quick-connect fitting 5, and the liquid inlet 14 on the server into the server's interior. After absorbing heat from various server components, it becomes high-temperature coolant, thus cooling the heat-generating components. It then flows through the liquid outlet 15 into the main liquid outlet pipe 11, and finally returns to the coolant distribution device 9 for cooling, continuously cycling through this process.

[0075] Optionally, the coolant distribution device can also be connected to the first detection switch circuit. After receiving the signal from the first detection switch circuit, it outputs coolant to the inlet branch corresponding to the first detection switch circuit, so that the coolant enters the liquid-cooled server and cools the liquid-cooled server.

[0076] Optionally, the coolant distribution device is also used to acquire the signal from the first detection switch circuit, determine the time when the liquid-cooled server is put into service and the total number of liquid-cooled servers put into service based on the received signal from the first detection switch circuit, and transmit coolant to the liquid-cooled server according to a preset coolant distribution strategy.

[0077] The coolant distribution strategy includes determining the coolant flow rate, transmission duration, and transmission gap of the coolant distribution device based on the number of liquid-cooled servers and their operating parameters.

[0078] Based on the number of liquid-cooled servers and their operating parameters, determine the coolant flow rate, transmission duration, and transmission interval of the coolant distribution device:

[0079] If the number of liquid-cooled servers reaches the first preset threshold, the heat output of each liquid-cooled server in the cabinet is determined according to the working parameters and heat output coefficient of the liquid-cooled servers. The heat output coefficient is a mapping function between the pre-determined working parameters of the liquid-cooled servers and the heat output of the liquid-cooled servers.

[0080] Based on the heat output of each liquid-cooled server in the cabinet, determine the total heat output of all liquid-cooled servers, and adjust the coolant flow rate, transmission time, and transmission gap of the coolant distribution device according to the total heat output.

[0081] Coolant flow rate and transmission time are positively correlated with total heat generation, while transmission gap is negatively correlated with total heat generation.

[0082] It is understood that by setting up a main inlet pipe 10, a main outlet pipe 11, an inlet branch pipe 12, and an outlet branch pipe 13, the present invention can achieve plug-and-play cooling of the liquid-cooled server 8. Through various bus interface connections, the server is decoupled from the cabinet 7. Before installing the server, only various quick connectors need to be installed on the server and the cabinet 7.

[0083] Figure 4 This is a schematic diagram of the front-end structure of the server mechanism provided by the present invention, as shown below. Figure 4 As shown, based on the above embodiments, as an optional embodiment, the server rack provided by the present invention further includes a power module 17 and a power bus 18, and the server is provided with a power connector;

[0084] The power module 17 is located inside the cabinet 7, and the power bus 18 is located on the cabinet 7. The power bus 18 is provided with at least one power socket corresponding to the power connector. The power plug is electrically connected to the power module and is used to supply power to the server.

[0085] Power module 17 connects to the cabinet head or small busbar via power interface 20 to power cabinet 7 and the server. The upper end of power bus 18 connects to power module 17, and the power cable connects to power module 17 via power interface 20 to achieve voltage and current conversion. After connection, power bus 18 has power supply capability. Liquid-cooled server 8 is equipped with a power connector, which connects to power bus 18 via blind plugging to power the server.

[0086] The power bus 18 is located in the middle of the rear of cabinet 7 and is fixed by the crossbeam of cabinet 7. Correspondingly, the power connector for the liquid-cooled server 8 should also be located in the middle of the server. The power connector should be installed on the server before it is mounted. The positions of the interfaces on the server correspond to the positions of the main boards on cabinet 7. The server is installed by inserting it from the front of cabinet 7. At the rear of cabinet 7, all interfaces on the server are connected to the interfaces on the bus of cabinet 7.

[0087] The inlet manifold 10, outlet manifold 11, power bus 18, and blind-plug frame are all modular optional accessories, and their quantity and position can be flexibly adjusted according to the actual application scenario. The inlet manifold 10, outlet manifold 11, and power bus 18 are reliably connected to the upper beam of the cabinet 7 through positioning holes and fixing brackets, and the space at the rear of the cabinet 7 is used to install various buses.

[0088] It is understood that the present invention connects through various bus interfaces, decoupling the server from the cabinet 7. Before installing the server, only various quick connectors need to be installed on the server and the cabinet 7.

[0089] Figure 5 This is a circuit diagram of the first detection switch circuit and the second detection switch circuit provided by the present invention, as shown below. Figure 5 As shown, based on the above embodiments, as an optional embodiment, the server rack provided by the present invention further includes a second detection switch circuit for detecting the connectivity between the power connector and the power socket.

[0090] The second detection switch circuit can be constructed using a detection switch sensor.

[0091] The rack and server connection method considered in this invention is a blind-plug connection between the server's interfaces and each bus, eliminating the need for manual on-site wiring. To ensure and detect correct server installation and connectivity, detection switch sensors are installed at the quick-connect joint between the server and the blind-plug mechanism, and at the location between the server's power interface and power bus 18. After the server is mounted and installed correctly, the detection switches close once the inlet, power supply, and outlet are connected. Simultaneously, indicator lights for each bus connection are installed on the front side of the rack 7. When the indicator lights illuminate, it indicates that the corresponding interface is correctly connected; all three lights illuminating indicate that the server is correctly installed, serving as a reminder and for maintenance purposes.

[0092] It is understood that the present invention uses detection elements at each bus interface to form a detection circuit, which can detect whether each interface of the server is correctly connected.

[0093] Based on the above embodiments, as an optional embodiment, the cabinet 7 is further provided with a switch 19, which is electrically connected to the server.

[0094] The cabinet 7 involved in this invention adopts a modular design for all parts and components that can be disassembled. The blind insertion mechanism, liquid inlet manifold 10, liquid outlet manifold 11, power bus 18, cold liquid distribution device 9, power module 17, switch 19, etc. can all be configured and added or removed according to the actual needs of the business. Their positions in the cabinet 7 can also be adjusted at will according to the actual situation.

[0095] It is understood that the present invention has multiple modular optional parts, and the quantity and position can be flexibly adjusted according to the actual application scenario.

[0096] Based on the above embodiments, as an optional embodiment, the cabinet 7 is provided with multiple mounting positions, and the blind insertion mechanism is detachably fixed to the mounting positions. The mounting positions are used to fix the liquid-cooled server 8 or directly fix the air-cooled server through the blind insertion mechanism.

[0097] The mounting positions are U-shaped, and each mounting position inside cabinet 7 can be equipped with a blind insertion mechanism.

[0098] Cabinet 7 is used to house liquid-cooled servers 8, and can also house air-cooled servers to adapt to different network application scenarios.

[0099] This invention enhances the compatibility between cold plate liquid-cooled cabinets and servers, improves the flexibility of matching between the two, and enables the application of servers of different sizes on the same cabinet; it solves the problem of difficulty in blind-plugging servers of different sizes on the same cabinet, and enables blind-plugging connection of servers of different sizes in the cabinet through blind-plug connectors on movable clamps, while also enabling the mixed use of liquid-cooled servers 8 and air-cooled servers.

[0100] Specifically, the blind-mating mechanism allows for the mounting of servers of different sizes. Servers with liquid cooling interfaces that meet rack size requirements can be mounted, achieving decoupling between the server and the rack. A quick-connect connector, which moves with the clamping component 2, is installed at the rear of the blind-mating mechanism. This allows for blind-mating of servers of different sizes that meet interface size requirements without requiring adjustments to the quick-connect connector position, enhancing compatibility. Compared to manually plugging and unplugging liquid-cooled racks, the use of a bus and blind-mating quick-connect connectors achieves both modular rack design and simplifies server installation. The position and quantity of each module can be flexibly adjusted according to actual needs. A reasonable and feasible detection circuit and indicator lights are installed to check the correct connection of each server interface, providing guidance for later maintenance. Pre-installation of various buses greatly reduces on-site installation work and compatibility with multiple server sizes reduces the need for server repositioning.
