Description

Technical Field

[0001] This utility model relates to the field of liquid cooling technology, specifically to a containerized liquid cooling system. Background Technology

[0002] The demand for data center construction and operation is increasing year by year, and the energy consumption and heat dissipation requirements of data centers are becoming more and more important. Immersion liquid cooling technology has significantly improved heat dissipation efficiency with its high-efficiency cooling capacity and is gradually replacing air cooling solutions as the mainstream heat dissipation technology.

[0003] Existing immersion liquid-cooled data centers generally consist of immersion liquid-cooled cabinets, CDU (cooling distribution unit) modules, and piping systems. However, current liquid-cooled data center construction solutions mainly rely on civil engineering, pipeline laying, and equipment installation, resulting in long cycles and high costs. Even when using containerized data center installation, there are still unreasonable layouts, which increases the difficulty of installation, use, and maintenance.

[0004] Therefore, optimizing the design and deployment of immersion liquid-cooled container data centers to improve efficiency, reduce costs, and enhance system scalability and ease of operation and maintenance has become an urgent problem to be solved. Utility Model Content

[0006] To achieve the above objectives, this utility model discloses a containerized liquid cooling system, which includes: a container and a cooling system housed in the container. The cooling system includes multiple liquid cooling cabinets and multiple heat exchange units. Multiple liquid cooling cabinets are provided on both sides of the container, and at least one heat exchange unit is provided on both sides of the container.

[0007] The heat exchange unit is located in the middle of a plurality of liquid-cooled cabinets on the same side as the heat exchange unit, and the heat exchange unit is used to exchange heat for the plurality of liquid-cooled cabinets on the same side.

[0008] Furthermore, the cooling system also includes a secondary side pipeline, which is located in the middle of the housing. The heat exchange unit on the same side of the housing is connected to a plurality of liquid cooling cabinets on both sides of the heat exchange unit through the secondary side pipeline.

[0009] Furthermore, the liquid-cooled cabinet includes a first liquid-cooled cabinet and a second liquid-cooled cabinet. The first liquid-cooled cabinet is larger than the second liquid-cooled cabinet. The first liquid-cooled cabinet and the second liquid-cooled cabinet are located on different sides of the container. The heat exchange unit includes a first heat exchange unit and a second heat exchange unit. Both the first heat exchange unit and the second heat exchange unit include a liquid pump and a plate heat exchanger. The number of liquid pumps and plate heat exchangers in the first heat exchange unit is greater than that in the second heat exchange unit. The first heat exchange unit corresponds to the first liquid-cooled cabinet, and the second heat exchange unit corresponds to the second liquid-cooled cabinet.

[0010] Furthermore, the secondary side piping includes a type I secondary side piping and a type II secondary side piping. The type I secondary side piping connects the first heat exchanger unit to a plurality of first liquid-cooled cabinets located on one side of the first heat exchanger unit. The type II secondary side piping connects the second heat exchanger unit to a plurality of second liquid-cooled cabinets located on both sides of the second heat exchanger unit.

[0011] Furthermore, the housing is provided with multiple maintenance doors, including a first group of doors and a second group of doors. The first group of doors is located on the two end walls of the housing, and the second group of doors is located on the two side walls of the housing. The second group of doors corresponds to the heat exchange unit.

[0012] Furthermore, the maintenance door also includes an inspection door, which is located on the side wall of the enclosure and adjacent to the back of the liquid-cooled cabinet.

[0013] Furthermore, the enclosure also houses an anti-static floor, which is disposed at the bottom of the enclosure and spaced apart from the bottom of the enclosure to form a receiving space.

[0014] Furthermore, the accommodating space is provided with cable management channels and pipe supports. The cable management channels are used to accommodate cables, and the pipe supports are used to support cooling pipes.

[0015] Furthermore, the enclosure also houses a power supply and distribution system, which is located at one end of the enclosure. The power supply and distribution system includes a control cabinet and a power supply cabinet, which are arranged sequentially along the length of the enclosure. The control cabinet is adjacent to the liquid-cooled cabinet, while the power supply cabinet is located away from the liquid-cooled cabinet.

[0016] Furthermore, the housing also accommodates guide rails and hooks. The guide rails include length limiting rails and width limiting rails. The length limiting rails are disposed on both sides of the top of the housing along the length direction, and the width limiting rails are disposed between the two length limiting rails. The width limiting rails are movable along the length direction of the length limiting rails. The hooks are disposed on and connected to the width limiting rails, and the hooks are movable along the length direction of the width limiting rails.

[0017] The containerized liquid cooling system design presented in this application demonstrates significant advantages in multiple structural and layout aspects, meeting the requirements for efficient heat dissipation, space optimization, convenient operation and maintenance, and system reliability. The containerized design enables the entire liquid cooling system to achieve high integration and mobility, allowing for rapid deployment in various scenarios, such as data centers, edge computing rooms, or temporary high-performance computing environments. The container structure's independence and modularity facilitate overall transportation, installation, and expansion, reducing deployment costs and time. The liquid-cooled cabinets are positioned on both sides of the container, leaving a central passageway. This allows for efficient heat dissipation through the liquid cooling system, preventing heat accumulation inside the container. The side-mounted layout creates a uniform cooling load distribution, facilitating overall coolant flow and management, enhancing heat dissipation balance. Furthermore, the side-mounted installation facilitates maintenance and operation; maintenance personnel can easily access the liquid-cooled cabinets through the central passageway, simplifying equipment inspection and repair. The passageway along the length of the container forms an independent operation and maintenance area, facilitating unified cabling and piping layout for the cooling system. The central passageway design optimizes airflow paths, improving ventilation and facilitating heat dissipation. Placing the secondary side piping at the bottom of the channel shortens the coolant's transmission path, reduces flow resistance, improves cooling efficiency, and avoids pipe interference in equipment areas, increasing system neatness and wiring standardization. It also reduces the risk of pipeline leaks affecting critical equipment. Furthermore, the unified arrangement of the secondary side piping facilitates centralized management and monitoring of the coolant, aiding in the rapid detection and handling of piping anomalies. Crucially, placing the heat exchanger units in the middle of the same-side liquid-cooled cabinets allows them to directly supply coolant to both cabinets, significantly shortening the coolant transmission distance and effectively improving heat exchange efficiency. This central arrangement ensures uniform coolant supply, avoiding uneven cooling performance due to differences in pipe length, and allows for more heat exchange units within a limited space, enhancing system cooling capacity and scalability to meet high-density computing loads. The heat exchanger units connect directly to multiple liquid-cooled cabinets via secondary side piping, reducing pipe branches and bends, thereby improving system reliability and reducing the risk of leaks during operation. The deployment structure of this application forms an optimized cooling path, in which the coolant can be evenly distributed from the middle position by the heat exchange unit through the secondary side pipeline and reach the liquid-cooled cabinet more quickly, thereby achieving uniform and rapid temperature control and meeting the heat dissipation requirements of high-density computing scenarios.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain this utility model and should not be construed as limiting it.

[0036] The terms "an embodiment," "example," or "example" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this application. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0037] To achieve the above objectives, this utility model discloses a containerized liquid cooling system, such as... Figure 1 and Figure 3 As shown, the containerized liquid cooling system 1 includes: a container 11 and a cooling system housed within the container 11. The cooling system includes pipes, multiple liquid cooling cabinets 22, and heat exchange units 23. Multiple liquid cooling cabinets 22 are provided on both sides of the container 11, and a passage along the length of the container 11 is formed between the liquid cooling cabinets on both sides of the container to facilitate personnel to enter the container for installation or maintenance. At least one heat exchange unit 23 is provided on both sides of the container 11. The heat exchange unit 23 is located in the middle of the multiple liquid cooling cabinets 22 on the same side as the heat exchange unit 23, and the heat exchanger is used to exchange heat for the multiple liquid cooling cabinets on the same side.

[0038] The cooling system also includes a secondary side pipe 21, which is located in the middle of the housing 11. The heat exchanger unit on the same side of the housing 11 is connected to multiple liquid-cooled cabinets on both sides of the heat exchanger unit through the secondary side pipe.

[0039] The containerized liquid cooling system 1 of this application demonstrates significant advantages in multiple structural and layout aspects to meet the requirements of efficient heat dissipation, space optimization, convenient operation and maintenance, and system reliability. The containerized design enables the entire liquid cooling system to achieve high integration and mobility, allowing for rapid deployment in various scenarios, such as data centers, edge computer rooms, or temporary high-performance computing environments. The container structure's independence and modularity facilitate overall transportation, installation, and expansion, reducing deployment costs and time. The liquid-cooled cabinets are positioned on both sides of the container 11, with a central passageway. This allows for efficient heat dissipation through the liquid cooling system, preventing heat accumulation inside the container 11. The side-mounted layout creates a uniform cooling load distribution, facilitating overall coolant flow and management, enhancing heat dissipation balance. Furthermore, the side-mounted installation facilitates maintenance and operation, and maintenance personnel can easily access the liquid-cooled cabinets through the central passageway, simplifying equipment inspection and repair. The passageway along the length of the container 11 forms an independent operation and maintenance area, facilitating unified cabling and piping layout for the cooling system. The central passageway design optimizes airflow paths, improving ventilation and facilitating heat dissipation. Placing the secondary side piping at the bottom of the channel shortens the coolant's transmission path, reduces flow resistance, improves cooling efficiency, and avoids pipe interference in equipment areas, increasing system neatness and wiring standardization. It also reduces the risk of pipeline leaks affecting critical equipment. Furthermore, the unified arrangement of the secondary side piping facilitates centralized management and monitoring of the coolant, aiding in the rapid detection and handling of piping anomalies. Crucially, placing the heat exchanger units in the middle of the same-side liquid-cooled cabinets allows them to directly supply coolant to both cabinets, significantly shortening the coolant transmission distance and effectively improving heat exchange efficiency. This central arrangement ensures uniform coolant supply, avoiding uneven cooling performance due to differences in pipe length, and allows for more heat exchange units within a limited space, enhancing system cooling capacity and scalability to meet high-density computing loads. The heat exchanger units connect directly to multiple liquid-cooled cabinets via secondary side piping, reducing pipe branches and bends, thereby improving system reliability and reducing the risk of leaks during operation. The deployment structure of this application forms an optimized cooling path, in which the coolant can be evenly distributed from the middle position by the heat exchange unit through the secondary side pipeline and reach the liquid-cooled cabinet more quickly, thereby achieving uniform and rapid temperature control and meeting the heat dissipation requirements of high-density computing scenarios.

[0040] The layout of liquid-cooled cabinets and heat exchanger units distributed on both sides, combined with a central aisle, makes full use of the container's internal space. Bottom-mounted piping reduces the footprint of pipelines in the operating area, resulting in a cleaner and more organized interior for container 11, while also improving overall space utilization. The centrally located heat exchanger units allow for flexible adjustments to the coolant supply route to adapt to dynamic changes in load. Furthermore, the modular layout of the central heat exchanger units can be easily expanded to support more liquid-cooled cabinets or higher cooling demands. The central aisle and bottom secondary piping arrangement centralizes the cooling system, allowing maintenance personnel to quickly perform equipment inspections and piping maintenance through a unified operating channel, reducing maintenance time and labor costs. The heat exchanger units' proximity to the liquid-cooled cabinets simplifies the coolant flow path, reducing pressure loss and potential failure points during liquid transport. The bottom piping layout reduces the risk of interference between the cabinets and pipes, further improving the overall system reliability.

[0041] The liquid-cooled cabinet includes a first liquid-cooled cabinet 22a and a second liquid-cooled cabinet 22b. The first liquid-cooled cabinet 22a is larger than the second liquid-cooled cabinet 22b. The first liquid-cooled cabinet 22a and the second liquid-cooled cabinet 22b are located on different sides of the container. The heat exchange unit includes a first heat exchange unit 23a and a second heat exchange unit 23b. Both the first heat exchange unit 23a and the second heat exchange unit 23b include a liquid pump and a plate heat exchanger. The first heat exchange unit 23a has a larger number of liquid pumps and plate heat exchangers than the second heat exchange unit 23b. The first heat exchange unit 23a corresponds to the first liquid-cooled cabinet 22a, and the second heat exchange unit 23b corresponds to the second liquid-cooled cabinet 22b.

[0042] The secondary side piping includes a type I secondary side piping 21a and a type II secondary side piping 21b. Type I secondary side piping 21a connects the first heat exchanger unit 23a to multiple liquid-cooled cabinets located on one side of the first heat exchanger unit 23a. Type II secondary side piping 21b connects the second heat exchanger unit 23b to multiple liquid-cooled cabinets located on both sides of the second heat exchanger unit 23b. This arrangement allows high-power liquid-cooled cabinets to be connected to the heat exchanger unit separately via secondary side piping, increasing heat exchange efficiency.

[0043] As an optional implementation method, such as Figure 2 As shown, the containerized cooling system of this application also includes an inlet manifold 211 and an outlet manifold 212. The inlet manifold 211 and the outlet manifold 212 connect the coolant transferred from the heat exchange components on both sides of the container to the cooling tower or other cooling device outside the container for primary heat exchange. The inlet manifold 211 and the outlet manifold 212 are located between the two heat exchange components near the top of the container.

[0044] The enclosure 11 has multiple maintenance doors, including a first set of doors 31 and a second set of doors 32. The first set of doors 31 are located on the two end walls of the enclosure 11, and the second set of doors 32 are located on the two side walls of the enclosure 11. The second set of doors 32 corresponds to the heat exchange unit. The first set of doors is located on the end side and is used to maintain the liquid cooling cabinets on both sides. However, the heat exchange unit is usually large in size, and it is inconvenient to maintain it inside. As a preferred option, a second set of doors is added at the enclosure corresponding to the heat exchange unit, so that personnel can perform maintenance on the heat exchange unit from the outside of the enclosure.

[0045] In some embodiments, such as Figure 2 As shown, the maintenance door also includes an inspection door 33, which is located on the side wall of the enclosure 11 and adjacent to the back of the liquid-cooled cabinet. The back of the liquid-cooled cabinet is generally equipped with cables and sensors. The first set of doors and the second set of doors cannot easily access the back of the liquid-cooled cabinet for maintenance. The inspection door is opened on the outside of the cabinet to facilitate maintenance.

[0046] like Figure 1 and Figure 4 As shown, the enclosure 11 also houses an anti-static floor 4. The anti-static floor 4 is located at the bottom of the enclosure 11 and is spaced apart from the bottom of the enclosure 11 to form a storage space. Preferably, the storage space is equipped with cable trays 7 and pipe supports. The secondary pipes are placed on the pipe supports in the storage space, which makes the cable routing neat and tidy, easy to maintain, and places the coolant pipes under the floor, so that even if there is a leak, the coolant will not come into contact with the outside, reducing contamination.

[0047] The enclosure 11 also houses a power supply and distribution system 5, which is located at one end of the enclosure 11. The power supply and distribution system 5 includes a control cabinet 51 and a power supply cabinet 52, which are arranged sequentially along the length of the enclosure 11. The control cabinet 51 is adjacent to the liquid-cooled cabinet, while the power supply cabinet 52 is located away from the liquid-cooled cabinet. The control cabinet is used to connect to the power and data cables of the liquid-cooled cabinet; their adjacent arrangement reduces cable length and path.

[0048] The enclosure 11 also houses guide rails and a hook 62. The guide rails include length limiting rails 61a and width limiting rails 61b. The length limiting rails 61a are located on both sides of the top of the enclosure 11 along its length direction. The width limiting rails 61b are located between the two length limiting rails 61a and can move along the length direction of the length limiting rails 61a. The hook 62 is mounted on and connected to the width limiting rail 61b and can move along the length direction of the width limiting rail 61b. The guide rails and hook facilitate the transportation, installation, and placement of the server within the enclosure.

[0049] Preferably, the containerized liquid cooling system of this application can be deployed in containers between 20 feet and 40 feet.

[0050] As an optional implementation method, such as Figure 2 As shown, the containerized cooling system of this application also includes an outdoor air conditioning unit 8a and an indoor air conditioning unit 8b, which enables ventilation and heat dissipation inside the container, further enhancing the heat dissipation effect.

[0051] As an optional implementation method, such as Figure 2 As shown, the containerized cooling system of this application also includes a network cable tray 9, which is installed on both sides of the container near the top. The network cable tray is used to support and store some cables connected from the liquid cooling cabinet, which are generally optical fibers or data cables. It is installed on the upper side for easy installation and connection.

[0052] As an optional implementation method, such as Figure 2 As shown, the containerized cooling system of this application also includes lamps 10, which are spaced apart along the length of the container to provide illumination.

[0053] The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above.
