[0002] With the rapid development of information technology in the world, mankind has quickly entered the cloud era. The demand for data storage and computing resources is increasing, the scale of data centers is also increasing, and their energy consumption is also increasing at an alarming rate. In addition to a small part of the electricity consumed by computer equipment being dissipated in the form of electromagnetic radiation, most of the electricity is eventually converted into heat energy. Therefore, there is a huge demand for heat dissipation in data centers. Generally, data centers use circulating air cooling, and the cold air sent in by the refrigeration unit is used to cool servers and other equipment. With the development of the industry and the increase in power density, the cooling capacity of the circulating air cooling method is also approaching its limit, and it cannot meet the cooling needs of the high-power density computer room layout. In addition, as the performance of the server improves, the power consumption also increases, and the power consumption of the cabinet increases exponentially, which cannot meet the heat dissipation needs.

However, such data centers are building computer rooms with civil structures, which occupy a large area and cannot meet the needs of mobility and rapid deployment. At the same time, the manufacturing and installation costs are too high. Utility Model Content

The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

[0025] References in this specification to "one embodiment" or "an example" or "an example" mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment of the present patent disclosure. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0026] Example:

[0027] like Figure 1 and Figure 2 As shown, this embodiment provides a liquid-cooled data center, including electronic information equipment 1 and a container 2. Figure 3 As shown, a coolant distribution module 4 is provided in the container 2, and liquid pools 3 are provided at opposite ends of the container 2. The liquid pools 3 include multiple layers of liquid tanks 31. The liquid tanks 31 are connected to the coolant distribution module 4 to add coolant to the liquid tanks 31. At least one electronic information device 1 immersed in the coolant is provided in each layer of the liquid tank 31.

[0028] In this embodiment, a data center that uses liquid cooling to dissipate heat is provided. The data center in the related art is a building machine room with a civil structure, which has a long construction period, high investment cost and difficulty in subsequent expansion. The data center in the present application includes a container 2 and electronic information equipment 1 stored in a centralized box. The container 2 is the carrier of the entire liquid-cooled data center, which provides physical protection and isolation. The electronic information equipment 1 is placed in the container 2. Since the container 2 is convenient for transportation, installation and relocation, the data center can be quickly moved, transported and installed, that is, the rapid movement and rapid layout of the data center are realized, and no civil construction is required, and the installation cost is low. A coolant distribution module 4 is provided in the container 2, which can pump the coolant from the liquid storage device (such as a cooling tower or a liquid storage tank) to the liquid pool 3, so that the coolant exchanges heat with the electronic information equipment 1 in the container 2, thereby meeting the heat dissipation requirements of the electronic information equipment 1. Figure 2 and Figure 3 As shown, the liquid pool 3 is arranged at two opposite ends of the container 2 along the arrow direction. In this embodiment, the container 2 is a rectangular parallelepiped structure, and multiple liquid pools 3 are arranged at one end of the container 2 along the length direction of the container 2, and multiple liquid pools 3 are also arranged at the other opposite end. The liquid pool 3 is arranged near the end of the container 2 to reserve more space in the middle of the container 2 to place other components, so that the components inside the container 2 are arranged more orderly and compact. The liquid pool 3 includes multiple layers of liquid tanks 31 arranged up and down, and the electronic information equipment 1 immersed in the cooling liquid is placed in the liquid tank 31. The liquid tank 31 is configured as multiple layers, so that the container 2 can accommodate more electronic information equipment 1, the structure is more compact, and the space utilization rate of the container 2 is improved.

[0029] In summary, multiple electronic information devices 1 (such as servers) are integrated into the container 2 using a modular design, making the data center structure more compact, occupying a smaller area, and having lower installation costs. In addition, the container 2 has good sealing performance, high structural strength, and a small footprint, which can ensure the effective operation of the coolant circulation system and the safe operation of the electronic information devices 1.

[0030] The liquid pool 3 includes a frame 32 fixed to the side wall of the container 2, and the multi-layer liquid tanks 31 are sequentially installed on the frame 32.

[0031] In this embodiment, the liquid pool 3 also includes a rack 32 fixed to the side wall of the container 2. The rack 32 is a supporting structure for the liquid tank 31. The liquid tank 31 can be installed on the rack 32 in sequence to achieve a multi-layer arrangement. The rack 32 is directly fixed to the side wall of the container 2 by fasteners, and can provide stable and firm support for the liquid tank 31 and the electronic information equipment 1 in the liquid tank 31, preventing the vibration generated during the flow of coolant and the operation of the equipment from causing adverse effects on the liquid tank 31 and the electronic equipment. In this embodiment, each liquid pool 3 includes two layers of liquid tanks 31 arranged up and down. In other embodiments, the number of liquid tanks 31 can also be adjusted according to the internal size of the container 2, such as 4 layers, 5 layers, etc.

[0032] A partition plate 311 is disposed in the liquid tank 31 to divide the liquid tank 31 into a plurality of cooling spaces.

[0033] In this embodiment, the partition plate 311 can divide the entire liquid tank 31 into a plurality of relatively independent cooling spaces, reduce the thermal interference between different spaces, and improve the overall efficiency of the cooling system. Each space can be optimized for a specific electronic information device 1 to achieve more precise temperature control and more efficient cooling. Specifically, three partition plates 311 are provided in this embodiment. In other embodiments, the number of partition plates 311 can also be set to 4, 5, etc. according to the volume of the liquid tank 31.

[0034] The cooling liquid distribution module 4 includes a plurality of liquid pumps, and the liquid pumps correspond to the liquid pools 3 one by one.

[0035] In this embodiment, the coolant distribution module 4 drives the coolant to flow to the liquid pool 3 and the liquid tank 31 through a liquid pump. The number of liquid pumps corresponds to the number of liquid pools 3, that is, one liquid pump is used to drive the coolant to flow to one liquid pool 3. Each liquid pump corresponds to a liquid pool 3, and each liquid pool 3 can be independently controlled, making the distribution of the coolant more accurate and uniform, avoiding the problem of uneven flow that may occur in traditional centralized pumping systems. According to the heat dissipation requirements of the electronic information equipment 1 in each liquid pool 3 and the temperature change of the coolant, the flow and pressure of the corresponding liquid pump can be adjusted in real time to ensure that the coolant in each liquid tank 31 can maintain the best heat dissipation effect.

[0036] A liquid inlet 312 and a liquid outlet 313 are respectively formed at two ends of the liquid tank 31 , and the liquid inlet 312 is communicated with the outlet of the corresponding liquid pump.

[0037] In this embodiment, the circulation path of the coolant is clear. The coolant enters the liquid tank 31 from the liquid inlet 312 driven by the liquid pump. After heat exchange with the electronic information device 1 in the liquid tank 31, the coolant with increased temperature flows out from the liquid outlet 313. During the circulation of the coolant in the liquid tank 31, the heat generated by the electronic information device 1 is continuously absorbed and taken away. The liquid inlet 312 and the liquid outlet 313 are arranged at opposite ends of the liquid tank 31 along its own length direction, ensuring that the flow path of the coolant in the liquid tank 31 is as long and uniform as possible, thereby increasing the time and area of ​​heat exchange and improving the heat dissipation efficiency.

[0038] The container 2 is provided with a drain port 22 and a supply port 21 connected to the coolant distribution module 4 . The supply port 21 is connected to an external cold source to deliver coolant to the coolant distribution module 4 . The drain port 22 is selectively connected to the liquid tank 31 .

[0039] In this embodiment, the liquid supply port 21 is an interface connecting an external cold source and the cooling liquid distribution module 4, which receives the cooling liquid after cooling treatment from the external cold source (such as a cooling tower, a chiller, etc.) and delivers it to the cooling liquid distribution module 4 to provide necessary heat dissipation support for the electronic information equipment 1 in the data center. The drain port 22 is used to discharge the cooling liquid whose temperature rises after the heat exchange is completed. The coolant with a lower temperature becomes a coolant with a higher temperature after heat exchange with the electronic information equipment 1 in the liquid tank 31, and is then delivered to the external cold source through the drain port 22 for cooling treatment, thereby forming a closed-loop cooling liquid circulation system. The drain port 22 is selectively connected to the liquid tank 31 so that the user can control whether the hot coolant is discharged from the container 2 or the timing of the hot coolant being discharged from the container 2.

[0040] Two liquid pools 3 are respectively arranged at two opposite ends of the container 2 , and a cooling liquid distribution module 4 for supplying liquid to the two liquid pools 3 is arranged between the two liquid pools 3 at the same end of the container 2 .

[0041] In this embodiment, two liquid pools 3 are respectively arranged at the two opposite ends of the container 2 in the width direction, that is, four liquid pools 3 are arranged in the container 2, and a cooling liquid distribution module 4 is arranged between the two liquid pools 3 located at the same end (front end or rear end), which can ensure that the two liquid pools 3 can receive cooling liquid at the same time and evenly, avoiding the problem of local overheating caused by uneven distribution of cooling liquid, thereby improving the heat dissipation efficiency of the entire data center. In addition, arranging the cooling liquid distribution module 4 between the two liquid pools 3 can make the structure of the entire liquid cooling system more compact, reduce the space occupied by the data center and reduce the construction cost, and the compact structure is also conducive to improving the stability and reliability of the system.

[0042] like Figure 4 As shown, a mounting frame 5 is provided in the middle of the container 2 , and the coolant distribution module 4 is installed on the mounting frame 5 .

[0043] In this embodiment, the container 2 is provided with a mounting frame 5, and the mounting frame 5 is arranged in the middle of the container 2 so that the coolant distribution module 4 is located at the center of the system, so as to achieve balanced distribution of the coolant among the multiple liquid pools 3 and reduce the problem of uneven flow caused by distance differences. The mounting frame 5 provides a more stable support for the coolant distribution module 4. The coolant distribution module 4 may be subjected to pressure and vibration from the liquid pump and the coolant flow during operation. The mounting frame 5 can more effectively disperse these forces and improve the overall stability of the system.

[0044] The liquid-cooled data center further includes a weak-current box 6 and a control box 7 , and both the weak-current box 6 and the control box 7 are installed on the mounting frame 5 .

[0045] In this embodiment, the weak current box 6 and the control box 7 are installed on the mounting frame 5, which can make full use of the vertical space in the container 2, reduce the ground occupation, and make the overall layout of the data center more compact and orderly. In addition, the control box 7 and the weak current box 6 are concentrated on the mounting frame 5, which is convenient for the operation and maintenance personnel to perform centralized management and maintenance. Once a failure occurs or adjustment is required, the operation and maintenance personnel can quickly locate the relevant equipment to improve maintenance efficiency.

[0046] A door 23 is formed on the front side wall and the rear side wall of the container 2 , and an openable and closable sealing door 24 is provided at the door 23 . The position of the sealing door 24 corresponds to the position of the liquid pool 3 .

[0047] In this embodiment, a door 23 is formed on the front side wall and the rear side wall of the container 2. The sealing door 24 is a sealing component used to close the door 23. The sealing door 24 can effectively isolate the external environment in a non-working state to prevent potential physical damage. In an emergency, the sealing door 24 can also serve as a safety barrier to prevent accidents such as coolant leakage from escalating. When the liquid cooling system needs to be maintained or repaired, the sealing door 24 can be easily opened, allowing the operation and maintenance personnel to directly access key components such as the liquid pool 3 and the coolant distribution module 4, thereby improving maintenance efficiency.
