[0002] In the field of liquid-cooled servers, with the rapid growth of data processing demand, the heat density inside the server has significantly increased, and the demand for efficient heat dissipation solutions is increasingly urgent.

However, the installation of the cold plate and the wiring of the water pipe in the liquid cooling system often need to occupy the valuable space of the rear window or front window of the server, which poses a challenge to the layout of the fans.

[0003] In related technologies, in order to bypass the water pipe and avoid conflicts with other structural components, compromises have been made in the number and layout of fans, and fans are usually limited to being installed in the same horizontal plane, which not only limits the number of fans but also increases the number of fan power boards, usually requiring a separate power board for each row of fans, resulting in increased costs and reduced space utilization efficiency, and failing to maximize the efficiency of liquid cooling and air cooling heat dissipation. In addition, in order to adapt to the special needs of the liquid cooling system, additional complexity may be introduced into the structural design, such as the need for additional fan plates and fan frame structural components, which not only increases costs but also makes the design and operation of the server more complex.

[0044] The heat dissipation assembly of the present application enables different fan modules 4 to share the same fan power supply board 2 by staggered arrangement and rotational installation of the plurality of fan modules and bilateral arrangement of the plurality of fan connectors 20 on the fan power supply board 2, thereby maximizing the number of fan modules 4 in a limited space, solving the problems of limited number of fans and excessive number of fan power supply boards in the related art, and thereby significantly improving the heat dissipation efficiency of the server, especially when handling high-load tasks, effectively maintaining the internal temperature of the server stable, avoiding system performance degradation or failure caused by overheating, not only effectively avoiding the occupation of fan installation space by the water inlet and outlet pipes of the cold plate, but also greatly reducing the manufacturing cost of the server by simplifying the number of fan power supply boards 2 and maintaining the consistency of the structure of the fan modules 4, and facilitating disassembly and assembly, which is mainly used in high-performance servers and data centers, especially in occasions requiring air-liquid hybrid heat dissipation.

[0045] The heat dissipation assembly of the present application comprises five fan modules 4, which have consistent structures and only differ in installation position and direction, each fan module 4 having a height of 80mm, a width of 80mm, and a depth of 86mm, and being installable in the rear plug-in box module of a 5U architecture liquid-cooled server.

[0049] The fan handle 432 on the fan module 4 of the present application is provided to facilitate the installation and removal of the fan module 4, and the fan module 4 is pushed into or pulled out of the fan cavity 12 through the fan handle 432, ensuring that the foolproof gap and the stop nail are aligned, thereby realizing the quick disassembly of the fan module and improving the convenience of maintenance and operation of the fan module 4, simplifying the server maintenance process, and reducing the risk of incorrect installation of the fan module 4.

The application is mainly applied in the rear plug-in box module of the server and data center, especially in the occasion requiring high-density layout of fan and power module.

[0060] The principle of the plurality of fan cavities 12 of the present application being staggered is to adjust the height of the fan cavity, so that different fan modules 4 can be installed at different heights, thereby maximizing the use of the space in the plug-in box body 1, improving the heat dissipation efficiency of the server, even in the presence of multiple cold plate water inlets and outlets, the plug-in box body 1 can install a sufficient number of fan modules 4, solve the problem of limited number of fans and increased cost of the server caused by the layout of the liquid cooling system in the related art, thereby improving the overall heat dissipation performance of the server, mainly applied to the server rear window design which needs to install fan modules 4 and cold plate water inlets and outlets in high density, especially in the case of limited internal space of the server, which needs to be laid out in detail.

[0061] As shown in Figures 10 to 15 , the plurality of fan cavities 12 include a first fan cavity 121 and a plurality of second fan cavities 122, the first fan cavity 121 is located between two adjacent second fan cavities 122 in the plurality of second fan cavities 122; and / or the plug-in box body 1 is provided with a plurality of cavities 14, the plurality of cavities 14 are arranged one-to-one corresponding to the plurality of fan cavities 12, the plurality of cavities 14 include a first cavity 141 and a second cavity 142, the first cavity 141 is located below the first fan cavity 121 and the cavity bottom surface of the first cavity 141 is flush with the cavity bottom surface of the second fan cavity 122, the second cavity 142 is located above the second fan cavity 122 and the cavity top surface of the second cavity 142 is flush with the cavity top surface of the first fan cavity 121; and / or the plurality of fan cavities 12 include a first fan cavity 121 and a plurality of second fan cavities 122, the plug-in box body 1 is provided with at least one first cold plate water inlet and outlet 151 and at least two second cold plate water inlets and outlets 152, the first cold plate water inlet and outlet 151 is located below the first fan cavity 121, and the at least two second cold plate water inlets and outlets 152 are arranged one-to-one above the plurality of second fan cavities 122.

[0062] The layout scheme of the fan cavities 12 adopted in the present application is to arrange the plurality of fan cavities 12 to include one first fan cavity 121 and a plurality of second fan cavities 122, the first fan cavity 121 being located between two adjacent second fan cavities 122 in the plurality of second fan cavities 122, so as to realize staggered installation of the fan modules 4 at different heights, maximize the space in the box body 1, ensure that all the fan modules 4 can share the same fan power board 2, avoid the sacrifice of the number of fans, simplify the installation process and reduce the cost, provide an innovative and practical solution for efficient heat dissipation of high-density servers, and ensure the compatibility of air cooling and liquid cooling, thereby improving the heat dissipation efficiency and economy of the server system as a whole.

Specifically, based on the premise that the positions of the first cold plate water inlet and outlet 151 and the second cold plate water inlet and outlet 152 are inconvenient to change, the first cold plate water inlet and outlet 151 is arranged below the first fan cavity 121, and the second cold plate water inlet and outlet 152 is arranged above each second fan cavity 122.
