Server liquid cooling structure and server

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to a Chinese patent application filed with the Patent Office of China on January 30, 2024, with application number 202410129900.X and application name “A Server Liquid Cooling Structure and Server,” the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present application relates to the technical field of server heat dissipation design, and in particular to a server liquid cooling structure and a server. Background Art

[0004] Heat dissipation is also a key issue in the current server design and development field, and will affect the development of data centers to a certain extent. Currently, the common server heat dissipation methods are air cooling and liquid cooling. Compared with air cooling, liquid cooling uses coolant as the refrigerant, and accurately cools the main high-power heating components such as CPU (central processing unit), GPU (graphics processing unit), memory, etc., with better heat dissipation effect and higher efficiency. It reduces noise pollution while reducing system energy consumption, and has good development prospects.

[0005] Common liquid-cooled servers generally choose to fix quick connectors on the rear window of the chassis. The server rear window is often equipped with related modules such as fans, power supplies, and I / O (input / output) interfaces. When the server is in the cabinet, it often needs to connect different external cables such as power cables, data cables, and network cables. As a result, the layout of the liquid cooling quick connector on the rear window will take up space, making the disassembly and assembly steps complicated.

For example, a detachable fixed connection refers to a state in which the positional relationship between at least two connected objects can be fixed in the installed state. Similarly, there are rotating connections, sliding connections, and the like.

[0061] 1 , a schematic diagram of the overall structure of a server liquid cooling structure provided by an embodiment of the present application is shown; the server liquid cooling structure may specifically include the following modules:

[0062] Chassis base 1, slide rail 2, cold plate quick connector module 3 and lever 4; cold plate quick connector module 3 includes cold plate quick connector first connector 31 and cold plate quick connector second connector 32;

[0063] The lever 4 is hingedly connected to the slide rail 2;

[0064] The slide rail 2 is located on the side of the chassis base 1;

[0065] The first cold plate quick-connect joint 31 is fixedly connected to the long arm end of the lever 4; the short arm end of the lever 4 is flush with the slide rail 2;

[0066] The second cold plate quick-connect joint 32 is fixedly connected to the side of the chassis base 1;

[0067] When the chassis base 1 slides along the slide rail 2 , the long arm end of the lever 4 rotates toward the chassis base 1 until the first cold plate quick-connect joint 31 is engaged with the second cold plate quick-connect joint 32 .

[0068] In this embodiment of the present application, a server liquid cooling structure includes a chassis base 1, slide rails 2, a cold plate quick-connector module 3, and a lever 4. The cold plate quick-connector module 3 includes a first cold plate quick-connector 31 and a second cold plate quick-connector 32. The first cold plate quick-connector 31 and the second cold plate quick-connector 32 are matching quick-connectors, and this embodiment of the present application does not limit the type of quick-connectors. The long arm end can be the first end, and the short arm end can be the second end.

[0069] Lever 4 is hingedly connected to slide rail 2. The hinge point of lever 4 can be connected to slide rail 2 via a pin or a connecting post. Slide rail 2 is located on the side of chassis base 1. When multiple slide rails 2 are provided, different slide rails 2 can be located on different sides of chassis base 1.

[0070] The first cold plate quick-connect joint 31 is fixedly connected to the long arm end of the lever 4; the short arm end of the lever 4 is flush with the slide rail 2; the second cold plate quick-connect joint 32 is fixedly connected to the side of the chassis base 1. When the chassis base 1 slides along the slide rail 2, the long arm end of the lever 4 rotates toward the chassis base 1 until the first cold plate quick-connect joint 31 and the second cold plate quick-connect joint 32 are engaged. That is, when the server is mounted on the rack and the chassis is pushed into the cabinet, the long rod end of the lever 4 contacts the rear end face of the chassis. As the chassis is pushed in, the lever 4 rotates around the rotation axis. Using the principle of leverage, the chassis pushes the long arm of the lever 4 outward, and the short arm of the lever 4 applies a force to one side of the first cold plate quick-connect joint 31 to assist in the insertion, thereby achieving the purpose of saving effort during the docking process.

[0071] In some embodiments of the present application, the lever 4 includes:

[0072] The lever body 41 is connected to the slide rail 2, and the first cold plate quick-connect joint 31 is fixedly connected to the long arm end of the lever body 41, and the short arm end of the lever body 41 is flush with the slide rail 2;

[0073] The elastic member is provided between the slide rail 2 and the lever body 41 ; it is used to push the first cold plate quick-connect joint 31 and the second cold plate quick-connect joint 32 to separate when the chassis base 1 is disengaged from the slide rail 2 .

[0074] In the embodiment of the present application, the lever 4 includes a lever body 41 and an elastic member. The lever body 41 is connected to the slide rail 2, and the first cold plate quick-connect joint 31 is fixedly connected to the long arm end of the lever body 41, while the short arm end of the lever body 41 is flush with the slide rail 2. Furthermore, the elastic member, the slide rail 2, and the lever body 41 are connected. When the elastic member is squeezed, it generates a certain elastic force on the slide rail 2 and the lever body 41. When the chassis base 1 is disengaged from the slide rail 2, it pushes the first cold plate quick-connect joint 31 and the second cold plate quick-connect joint 32 to separate.

[0075] In practice, when the chassis is pushed in, the lever body 41 rotates about the axis of rotation and compresses the elastic member. The chassis pushes the long arm of the lever body 41 outward, and the short arm of the lever 4 applies a force to one side of the first cold plate quick connector 31 to assist in insertion. Furthermore, when the chassis is pulled out, the elastic force of the elastic member quickly disengages the first cold plate quick connector 31 and the second cold plate quick connector 32, thereby achieving a quick-disconnect mechanism.

[0076] In some embodiments of the present application, the elastic member is a torsion spring.

[0077] One end of the torsion spring is connected to the slide rail 2 , and the other end is connected to the lever body 41 . The center line of the torsion spring is located at the hinge point where the lever 4 is hinged to the slide rail 2 .

[0078] When the torsion spring is compressed in the direction of rotation when the lever 4 rotates, the elastic force generated can better act on the first cold plate quick connector 31 and the second cold plate quick connector 32 when released, thereby improving the separation efficiency of the first cold plate quick connector 31 and the second cold plate quick connector 32.

The power backplane bracket 5 can be connected to a power supply to power the server. The mid-backplane 6 can be disposed inside the chassis base 1 and fixedly connected to the chassis base to isolate the liquid cooling water path and thus divide the hardware areas.

When the second cold plate quick-connect joint 21 is connected to the side of the chassis base 1, the connection and positioning are achieved through the first positioning hole and the first positioning pin.

[0092] In some embodiments of the present application, the cold plate quick connector module 3 further includes:

[0093] The guide module is located between the first cold plate quick connector 31 and the second cold plate quick connector 32 and is used to guide the movement of the first cold plate quick connector 31 and the second cold plate quick connector 32 when they are close to each other.

Through the cooperation of the male joint and the female joint, the first cold plate quick-connect joint 31 and the second cold plate quick-connect joint 32 can be quickly disassembled and assembled.

[0122] Based on the above, let's take an example to illustrate:

[0123] The server liquid cooling structure includes a chassis base 1, slide rails 2, a cold plate quick-connector module 3, a lever 4, a mid-backplane 6, a power supply backplane bracket 5, and a cold plate module. Lever 4 is fixed to the chassis slide rail 2. Lever 4 utilizes the principle of lever 4 to save effort and assist operators in installing and removing quick-connectors. A first cold plate quick-connector 31 is provided on the lever 4, and a second cold plate quick-connector 32 is provided on the side of the chassis to match it. A second guide 322 (a positioning groove) is provided on a second fixing block 323 on one side of the second cold plate quick-connector 32, corresponding to a first guide 312 (a positioning pin) on a first fixing block 313 on one side of the first cold plate quick-connector 31. The second cold plate quick-connector 32 is secured between the mid-backplane 6 and the power supply backplane bracket 5 with four side screws to ensure reliable insertion. The first cold plate quick-connector 31 is secured to the lever 4 via a first structural member 311. After the water channel is connected, a cold plate quick-connect first joint 31 is fixed to the end of the long arm of the lever 4 , and the end of the short arm of the lever 4 is flush with the rear end surface of the chassis base 1 .

[0124] As shown in Figures 2-3, the lever 4 is fixed to the outside of the chassis slide rail 2 and is connected by a pin 42 to achieve rotation. The slide rail 2 is fixed to the cabinet rack. When the server is put on the rack, the chassis is pushed into the cabinet, and the long rod end of the lever 4 contacts the rear end surface of the chassis. As the chassis is pushed in, the lever 4 rotates around the rotation axis. Using the lever principle, the chassis pushes the long arm of the lever 4 to move outward, and the short arm of the lever 4 will apply a force to one side of the first quick-connect joint of the plate to assist in plugging in, thereby achieving the purpose of saving effort during the docking process. After the liquid cooling quick connector fixed inside the chassis and on the slide rail 2 is plugged in, the water channel is connected. During the process of pulling out the chassis, due to the elastic force of the elastic member, the first quick-connect joint 31 of the cold plate and the second quick-connect joint 32 of the cold plate are quickly disengaged to achieve separation. The entire operation process is convenient and quick. Using the lever 4, no large force is required during the plugging of the quick connectors, which is relatively convenient and can achieve quick plugging and unplugging.

[0125] As shown in Figure 5, two second guide members 322 are provided on the second fixing block 323, and two first guide members 312 are provided on the lever 44 to cooperate with them. The length of the second guide member 322 is sufficient to guide and position the second guide member 322 and the first guide member 312 before the first cold plate quick connector 31 and the second cold plate quick connector 32 are plugged into each other. As the chassis is pushed in, the two guide members cooperate with the first guide member 312 to allow the first cold plate quick connector 31 and the second cold plate quick connector 32 to be plugged into each other.

[0126] As shown in Figures 4-6, the liquid cooling system primarily consists of connecting pipes 324 and a cold plate module 7. The coolant in the cold plate module 7 is transferred via connecting pipes 324 to the cold plate quick-connect second connector 32, secured between the mid-backplane 6 and the power backplane bracket 5, completing the connection. The cold plate quick-connect second connector 32 is secured to the lever 4 of the chassis rail 2, allowing for rotational insertion. Once the chassis is inserted into the cabinet and the pipes are connected, during the inlet phase, the coolant distribution unit directs the coolant from the connecting pipes 324 on the chassis sidewalls to components requiring heat dissipation, such as the CPU or GPU liquid cooling modules. During the outlet phase, the coolant flowing out of the cold plate module flows back to the chassis sidewalls via the outlet connecting pipes 324 and ultimately back to the coolant distribution unit on the cabinet. By utilizing the space on the chassis sidewalls without occupying the space on the chassis rear window, the quick-connect connection is achieved using the principle of lever 4, achieving cooling and heat dissipation of the heat-generating components. The coolant flows through the liquid cooling quick connector, passes through the CPU or GPU module related devices, and then flows back from the side wall of the chassis to the CDU (coolant cooling unit) or Mainfold (collection box) to achieve heat dissipation.

[0127] The server liquid cooling structure in the embodiment of the present application can realize the connection of the liquid cooling water pipe from the side wall space of the server chassis. By utilizing the principle of lever 4, the two quick connectors are plugged into each other during the process of pushing the server into the cabinet when it is put on the rack, and the water circuit is connected. When the chassis is pulled out, the two quick connectors are quickly disengaged to achieve separation, thereby solving the problems of low space utilization of the pipe connector layout of the liquid cooling server, complex structural design, low operation and maintenance efficiency, and inconvenient operation, saving costs, improving work efficiency, and reducing the investment of manpower, financial resources, and material resources.
