Description
Technical Field
[0001] The present invention relates to the technical field of servers, and particularly to a liquid cooling structure and a server. Background Art
[0002] With the continuous improvement of the performance requirements for servers, the heat dissipation problem of servers has become a key and difficult point. Due to the relatively complex system structure of servers, conventional air cooling can no longer meet its heat dissipation requirements, and the liquid cooling solution has better heat dissipation performance compared to the air cooling solution.
[0003] In the liquid cooling solution, the liquid cooling structure requires more space, resulting in a contradiction with the increasingly compact space layout of the current system design. Especially when there are fans, power supplies, and I / O interfaces and other related modules arranged at the rear window of the server, too many liquid cooling quick connectors will also occupy the layout space of other functional components. At the same time, the layout of the liquid cooling pipelines will also affect or reduce the performance of the server product.
[0004] In the prior art, the layout of the coolant pipelines usually adopts a front-to-back through type, that is, the coolant is introduced from the liquid inlet pipeline at the rear window, flows through modules with high heat dissipation requirements such as GPUs and CPUs, and then flows out from the rear window to achieve liquid cooling of the server. However, this method requires a large pipeline layout space inside the server from the front window to the rear window and no device obstruction. However, there are differences in the structures of some servers, and the middle backplane installed divides the server into front and back parts. In this case, the flow path of the coolant is cut off, and the direct front-to-back through structure layout of liquid cooling is difficult to apply. Summary of the Invention

[0044] To make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the attached drawings and specific implementation manners. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.
[0045] In the embodiment of the present invention, the coolant flows in from the rear window, flows through the external modular liquid cooling pipeline system, then flows into the CPU or GPU module respectively and flows out from their respective front windows, and then flows into the external modular liquid cooling management system and flows out from the rear window. Each pipeline converges in the pipeline tray module of the external modular liquid cooling pipeline system and is connected to the CDU (Coolant Distribution Units) or Mainfold (manifold) through the pipeline tray module to realize the import and export of the coolant.
[0046] Specifically, by utilizing the idle space on the upper layer of the GPU board, a separate pipe tray module is designed, and the CPU or GPU module is connected through a liquid cooling block connector. The liquid cooling system introduces the coolant from the rear window through the pipe tray module, and the coolant flows into the CPU / GPU module from the front window of the CPU or GPU module through the liquid cooling quick connector. After flowing through the related components of the CPU or GPU module, it flows out from the front window, flows into the pipe tray module, and then is guided back to the CDU or Mainfold from the rear window.
[0047] Through the embodiments of the present invention, when the space for arranging pipelines is extremely limited and the coolant pipeline cannot pass through the front and rear windows, a liquid cooling heat dissipation method in which liquid enters and exits the front windows of the CPU module and the GPU module is utilized, and the idle space of the chassis is utilized to design a pipeline tray module connected to the CDU or Mainfold, thereby providing liquid inlet and outlet paths for the CPU and GPU modules, thereby solving the problem of liquid cooling heat dissipation of the CPU and GPU modules.

After flowing through the CPU or GPU module, it flows back to the module's liquid outlet pipe at the front window, and then is guided back to the CDU or Mainfold at the rear window, providing liquid inlet and outlet pipelines for the GPU liquid cooling module and the CPU liquid cooling module, thereby maximizing the utilization of the server structure space.
[0051] 2. The GPU liquid cooling module and the CPU liquid cooling module both have liquid inlet through the front window.
