Description

Technical Field

[0001] This utility model relates to a data center, and more particularly to a liquid-cooled, energy-saving integrated data center. Background Technology

[0002] A data center, also known as a server room, is a facility that provides an operating environment for computer systems, servers, network equipment, and storage systems. The main function of a data center is to store, process, and distribute data. It is an indispensable infrastructure in modern information society, used for internet services, cloud computing, and big data analytics, and has a wide range of applications. Currently, data centers generally use air-cooled air conditioning to meet cooling requirements. However, with increasingly stringent national energy-saving requirements for data centers, this existing air-cooled air conditioning solution suffers from high energy consumption, resulting in a high Power Usage Effectiveness (PUE), which cannot meet the energy-saving requirements of current applications. Power Usage Effectiveness = Total Energy Consumption (IT Energy Consumption + Air Conditioning Energy Consumption + Other) / IT Energy Consumption. Although data centers with liquid cooling systems are now being offered on the market, these existing data centers still require an outdoor unit for heat dissipation within their liquid cooling systems. At the same time, the air-cooled parts of the servers still require an air-cooled rack air conditioner, which also needs an outdoor unit for heat dissipation. Therefore, current liquid-cooled data centers still suffer from high power consumption, large installation workload, and less than ideal energy-saving effects. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a liquid-cooled energy-saving integrated data center, which aims to optimize the structure and heat dissipation scheme of the integrated data center in order to reduce its power consumption and installation workload, and improve its energy-saving effect.

The water collector is connected to the water pump and is circulated to the heat exchanger through the water pump. The coolant after heat exchange is distributed to each liquid cooling server through the water distributor, thereby forming a circulating heat exchange structure.

[0008] A further improvement of this invention is that the coolant includes deionized water.

[0009] A further improvement of this invention is that it also includes a hose, through which the water distributor and the water collector are respectively connected to each liquid-cooled server.

[0010] A further improvement of this utility model is that it also includes a monitoring host, which is connected to the liquid cooling distribution unit.

[0011] A further improvement of this utility model is that the second isolation plate is a movable baffle, which is disposed on the side of the server rack away from the water manifold and above the air intake side of the second area.

[0012] A further improvement of this invention is that a second cooling fan is provided on the top of the server rack.

[0013] A further improvement of this utility model is that it also includes an uninterruptible power supply and a power distribution module, wherein the uninterruptible power supply is connected to the liquid cooling distribution unit and the liquid cooling server respectively through the power distribution module.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: A first isolation plate and a second isolation plate are respectively set at both ends of the server rack, dividing the server rack into a first area and a second area from top to bottom through the first and second isolation plates; wherein, the first area is a liquid-cooled sealed area for housing liquid-cooled servers; the second area is an air-cooled area for housing the liquid-cooling distribution unit; and each liquid-cooled server is connected to the liquid-cooling distribution unit through the manifold, thereby achieving an optimized design of the integrated data center structure and heat dissipation scheme through the liquid-cooling distribution unit, the manifold, and the server rack including the first and second areas, effectively reducing its power consumption and improving its energy-saving effect; based on this, this utility model eliminates the need for air-cooled air conditioners and outdoor units, significantly reducing the required installation workload.

[0029] The preferred embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] like Figures 1 to 3 As shown, this embodiment provides a liquid-cooled energy-saving integrated data center, including: a server rack 1, a liquid-cooled distribution unit 2, and a manifold 3. A first isolation plate 101 and a second isolation plate 102 are respectively installed at both ends of the server rack 1. The first isolation plate 101 and the second isolation plate 102 divide the server rack 1 into a first area 103 and a second area 104 from top to bottom. The first area 103 is a liquid-cooled sealed area used to house liquid-cooled servers 4; the second area 104 is an air-cooled area used to house the liquid-cooled distribution unit 2. Each liquid-cooled server 4 is connected to the liquid-cooled distribution unit 2 through the manifold 3.

[0031] In this embodiment, a first isolation plate 101 and a second isolation plate 102 are respectively provided at both ends of the server rack 1. The two ends of the server rack 1 can be the front and rear ends of the server rack 1. The server rack 1 is divided into a first area 103 and a second area 104 from top to bottom by the first isolation plate 101 and the second isolation plate 102. The first area 103 is a liquid-cooled sealed area for housing liquid-cooled servers 4. The front and rear ends of this liquid-cooled sealed area can be sealed with sheet metal, providing a good sealed space foundation for ensuring the safety of important equipment. Optionally, in this server rack 1, the monitoring host 6, the uninterruptible power supply 7, and the power distribution module 8 are also located in the first area 103 to better meet the actual monitoring and power supply needs and facilitate wiring. The second area 104 is an air-cooled area for housing the liquid-cooled distribution unit 2, which refers to the Cooling Dispensing Unit, also known as a CDU or cold liquid distribution unit. Each liquid-cooled server 4 is connected to the liquid-cooled distribution unit 2 through the manifold 3. Therefore, this embodiment can optimize the structure and heat dissipation scheme of the integrated data center through the liquid cooling distribution unit 2, the water manifold 3, and the server rack 1 including the first area 103 and the second area 104, effectively reducing its power consumption and improving its energy-saving effect; on this basis, this embodiment does not require the use of air-cooled air conditioners and no longer needs to configure outdoor units, which can significantly reduce the required installation workload.

[0032] like Figure 1 and Figure 3 As shown, in this embodiment, the front and rear ends of the second region 104 are respectively provided with ventilation mesh 105. The mesh 105 can be directly installed on the front and rear doors of the second region 104, allowing the second region 104 to communicate with the outside through the mesh 105, thus enabling heat dissipation of the liquid-cooled distribution unit 2. Optionally, in this embodiment, the second region 104 is provided with a first cooling fan 106 to improve the ventilation and heat dissipation effect of the second region 104. The first cooling fan 106 can be a blower, and its installation location is not limited, depending on the actual situation and requirements.

[0033] like Figure 3As shown, the liquid-cooled distribution unit 2 in this embodiment includes a water pump 201 and a heat exchanger 202. The water distribution manifold 3 includes a water distributor 301 and a water collector 302. In actual operation, coolant enters the water distributor 301 and is then distributed to each liquid-cooled server 4, carrying away the heat from each liquid-cooled server 4 to achieve heat exchange. At this time, the temperature of the coolant rises, becoming hot water. The cooled coolant (hot water) after heat exchange is then collected in the water collector 302, which is connected to the water pump 201. The collected coolant is then circulated by the water pump 201 to the heat exchanger 202, where it undergoes another heat exchange with the cold air entering the second region 104. At this time, the hot water becomes cold water, and the cold air becomes hot air. Finally, the cooled coolant (cold water) after the second heat exchange is redistributed to each liquid-cooled server 4 through the water distributor 301, thus forming a circulating heat exchange structure. Optionally, the heat exchanger 202 is a finned heat exchanger to improve heat exchange efficiency.

[0034] In this embodiment, a liquid cooling system replaces the traditional air-cooled air conditioner in the first region 103. Therefore, only a water pump 201 is needed to circulate the coolant. The power consumption of this water pump 201 is much lower than that of the compressor in a traditional air-cooled air conditioner, making the power consumption of this embodiment significantly lower than that of traditional air-cooled air conditioner solutions. The coolant in this embodiment includes deionized water. Using deionized water can prevent scaling and conductivity, thus better meeting practical application requirements.

[0035] like Figures 1 to 3 As shown, optionally, this embodiment also includes a hose 5, through which the water distributor 301 and the water collector 302 are respectively connected to each liquid-cooled server 4. The liquid-cooled distribution unit 2 uses a water pump 201 to evenly distribute the cooled deionized water to each liquid-cooled server 4 through the water distributor 301 and the hose 5. In the liquid-cooled server 4, the deionized water absorbs heat from heat-generating devices such as GPUs, causing the temperature of the deionized water to rise. Then, the water is collected through the hose 5 and the water collector 302 and returned to the liquid-cooled distribution unit 2 to quickly establish its connection and provide a basis for the even distribution and collection of deionized water.

[0036] Optional, such as Figure 1 and Figure 2As shown, this embodiment also includes a monitoring host 6, which is connected to the liquid-cooled distribution unit 2. The monitoring host 6 can optionally be located in the first area 103. This embodiment also includes an uninterruptible power supply (UPS) 7 and a power distribution module 8. The UPS 7 is connected to the liquid-cooled distribution unit 2 and the liquid-cooled server 4 respectively through the power distribution module 8, so as to provide uninterrupted power supply to the liquid-cooled distribution unit 2 and the liquid-cooled server 4. Through the above optimized design, this embodiment can provide a foundation for monitoring the liquid-cooled distribution unit 2, the UPS 7, the power distribution module 8, and the environment, so as to monitor the operating status of each basic device in real time.

[0037] Optional, such as Figure 2 As shown, in this embodiment, the second isolation plate 102 is a movable baffle. The movable baffle is located on the side of the server rack 1 away from the water manifold 3, and is positioned above the air intake side of the second area 104. Correspondingly, a second cooling fan 107 is provided on the top of the server rack 1 in this embodiment.

[0038] The movable baffle described in this embodiment can be controlled by the monitoring host 6. When the monitoring host 6 detects through the temperature sensor 108 that the temperature inside the server rack 1 exceeds a first preset threshold, the movable baffle is opened, and simultaneously the second cooling fan 107 located at the top of the server rack 1 is turned on, allowing cool outdoor air to enter through the movable baffle, dissipating heat from the liquid-cooled server 4 in the server rack 1, and exhausting from the second cooling fan 107 at the top of the server rack 1. When the temperature is lower than the second preset threshold, the movable baffle is closed, and the second cooling fan 107 is turned off. The first preset threshold refers to the temperature threshold for controlling the opening of the movable baffle of the server rack 1, and the second preset threshold refers to the temperature threshold for controlling the closing of the movable baffle of the server rack 1. Both temperature thresholds can be set and adjusted according to actual conditions and requirements.

[0039] The liquid-cooled energy-saving integrated data center described in this embodiment may include a server rack 1, a liquid-cooled distribution unit 2, a manifold 3, hoses 5, a monitoring host 6, an uninterruptible power supply 7, and a power distribution module 8. The liquid-cooled distribution unit 2, manifold 3, monitoring host 6, uninterruptible power supply 7, and power distribution module 8 can all be pre-assembled into the server rack 1. During on-site construction, only the liquid-cooled server 4 needs to be installed. The liquid-cooled server 4 is then connected to the hoses 5 of each branch on the manifold 3 via hose connectors, and the power supply is connected to enable the entire system to operate. Therefore, this embodiment is easy to install and maintain, has low construction difficulty, and effectively reduces the requirements for construction personnel.

[0040] The specific embodiments described above are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes, but is not limited to, these specific embodiments. All equivalent changes made in accordance with the shape and structure of this utility model are within the protection scope of this utility model.
