Description

Technical Field

[0001] This utility model relates to the field of liquid cooling technology, and in particular to a fully liquid cooling system for combining a liquid-cooled back door with a chiller. Background Technology

[0002] A data center is a physical location that centrally stores, manages, and processes data, and provides computing and network services. It integrates hardware such as servers, storage devices, network switches, cooling systems, and power supply equipment, along with software such as operating systems, databases, and middleware, to achieve core functions such as data storage and management, network interaction hubs, and business continuity assurance.

[0003] Data center cooling systems primarily consist of air cooling and liquid cooling. Air cooling is currently the most common and widely used cooling method in data centers. It uses fans to force airflow and remove heat generated by internal server components. Liquid cooling is divided into cold plate liquid cooling and immersion liquid cooling. Cold plate liquid cooling uses a metal cold plate in close contact with the heat-generating components, utilizing a heat-conducting medium to remove heat; it is suitable for high-power servers. Immersion liquid cooling completely immerses the server in a non-conductive coolant, using the liquid's boiling and vaporization to remove heat. However, existing data center liquid cooling systems are inconvenient to expand. When adding a rack, it is necessary to replan and lay coolant piping to ensure that the servers in the new rack can connect to the existing coolant circulation system. Utility Model Content

[0023] Specifically, multiple server racks 5 are arranged side-by-side in sequence. Each server rack 5 is identical in size and structure. The chiller unit 1 is independently installed with each server rack 5, providing a cooling source to enable liquid cooling. A liquid-cooled back door 2 is fixedly installed on the back of each server rack 5, allowing for heat dissipation. Supply and return liquid pipes 23 and 24 are installed on each server rack 5, extending along the width of the rack. Both supply and return liquid pipes 23 and 24 are located on the top of the server rack 5 and are fixedly installed on it. The end of 24 is provided with a connector, so that when each cabinet 5 is placed side by side, the liquid supply pipes 23 of each cabinet 5 are connected in sequence to form a connected liquid supply pipe 23. The connected liquid supply pipe 23 is connected to the liquid outlet of the chiller unit 1 through the liquid supply pipe. Similarly, the liquid return pipes 24 of each cabinet 5 are also connected in sequence to form a connected liquid return pipe 24. The connected liquid return pipe 24 is connected to the liquid return port of the chiller unit 1 through the liquid return pipe.

[0024] In this embodiment, each liquid-cooled back door 2 is provided with an open heat dissipation chamber 21, and a cooling pipe assembly 22 is provided inside the heat dissipation chamber 21. The side of the heat dissipation chamber 21 corresponding to the cabinet 5 is open, so that air can be delivered into the heat dissipation chamber 21 for heat exchange. The cooling pipe assembly 22 includes a cooling pipe 221 fixedly installed in the heat dissipation chamber 21. The cooling pipe 221 can adopt a serpentine structure or other shapes commonly used in the prior art. The top of the cooling pipe 221 has an inlet pipe 222 and an outlet pipe 223. The inlet pipe 222 is used to transport liquid refrigerant into the cooling pipe 221. After being transported along the cooling pipe 221, the liquid refrigerant is output from the outlet pipe 223. The inlet pipe 222 on the cooling pipe 221 is connected to the liquid supply line 23, and the outlet pipe 223 on the cooling pipe 221 is connected to the liquid return line 24.

Each cabinet 5 is equipped with a liquid supply pipe 23 and a liquid return pipe 24. The cooling pipe assemblies 22 are connected to the liquid supply pipe 23 and the liquid return pipe 24. Thus, during use, the liquid supply to each cabinet 5 is... Pipes 23 are connected in sequence to form a continuous liquid supply pipe 23. This continuous liquid supply pipe 23 is connected to the liquid outlet of the chiller unit 1 through the liquid supply pipe. The return liquid pipes 24 of each cabinet 5 are also connected in sequence to form a continuous return liquid pipe 24. This continuous return liquid pipe 24 is connected to the return liquid outlet of the chiller unit 1 through the return liquid pipe. In this way, adding or removing cabinets 5 is simple to operate and can be installed and connected quickly. The heat dissipation effect inside each cabinet 5 can be controlled through the chiller unit 1.

There are multiple air inlets 311 and they are arranged in one or two areas of the liquid cooling back door 2. Thus, in one or two air inlet hole 311 areas of the liquid cooling back door 2, the air inlet 312 can be a circular or rectangular structure. The air outlet structure 32 includes an air outlet hole 321 and an air outlet 321 disposed on the liquid cooling back door 2. There are also multiple air outlet holes 321 and they are arranged in one or two areas of the liquid cooling back door 2. Thus, in one or two air outlet hole 321 areas of the liquid cooling back door 2, the air outlet 321 can be a circular or rectangular structure.

[0030] In this embodiment, preferably, the movable adjustment plate 4 includes a first sliding plate 41 and a second sliding plate 43 that slide on the liquid-cooled back door 2. The first sliding plate 41 is correspondingly arranged with the air inlet structure 31 and is slidably connected to the liquid-cooled back door 2. A first driving component 42 is connected to the first sliding plate 41. The first driving component 42 may be a piston driving rod or other driving structure.

In this case, the length of the first sliding plate 41 and the second sliding plate 43 is less than the length of the liquid-cooled back door 2. The first sliding plate 41 and the second sliding plate 43 can also slide along the width direction of the liquid-cooled back door 2. In this case, the width of the first sliding plate 41 and the second sliding plate 43 is equal to half the width of the liquid-cooled back door 2. The following example illustrates that the first sliding plate 41 and the second sliding plate 43 can also slide along the width direction of the liquid-cooled back door 2.

At this time, airflow is achieved through the first air intake through-hole area 4111 and the second air intake through-hole area 4112, and the opening range of the air intake structure 31 is small. When the first sliding plate 41 moves to the second working position, the first sliding plate 41 is offset from the air intake structure 31, thereby fully exposing the air intake hole 311 area and the air intake 312. This allows the air intake hole 311 area and the air intake 312 to be fully opened, that is, airflow is achieved through the air intake hole 311 area and the air intake 312. At this time, the air intake structure 31 is opened to a large extent.

The second sliding plate 43 is driven by the second driving member 44 and has a first working position and a second working position.

At this time, the air outlet structure 32 is opened to a large extent.
