Description

Technical Field

[0001] The utility model belongs to the technical field of data center refrigeration, and specifically relates to a liquid cooling computing power system. Background Art

[0002] With the rapid development of information technology and the continued advancement of digitalization, data centers, as core infrastructure for information processing and storage, are becoming increasingly important and significant. However, as the number of devices and power density in data centers continue to increase, energy consumption and heat dissipation issues are becoming increasingly prominent. To address these challenges, efficient heat dissipation technologies such as cooling towers and coolant cooling units (CDUs) have emerged, becoming a key component in ensuring stable data center operations.

[0003] Existing cooling towers utilize water-cooled cooling towers, a crucial component of a data center's water cooling system. Their primary function is to effectively dissipate heat generated within the data center into the atmosphere through heat exchange between water and air. Compared to traditional air cooling systems, water-cooled systems offer higher heat dissipation efficiency and lower energy consumption. Water-cooled cooling towers utilize water's high specific heat capacity to remove heat generated by equipment through circulating water, completing the heat exchange process within the cooling tower. The coolant cooling unit (CDU) is a core component of data center liquid cooling technology. It is responsible for evenly dissipating coolant to various heat-generating components within the data center and dissipating heat through heat exchange. The CDU typically works in conjunction with other equipment, including water pumps, water tanks, and heat exchangers, to form a complete liquid cooling circulation system. Within a data center's water cooling system, the water-cooled cooling tower and CDU work together to achieve efficient heat dissipation. The water-cooled cooling tower dissipates heat generated within the data center into the atmosphere, while the CDU ensures precise heat transfer and dissipation within the data center. These two components work together to form a complete heat dissipation cycle, ensuring stable operation of data center equipment.

[0004] However, the water-cooled cooling tower in the existing technology faces high water resource consumption, and the heat dissipation effect of the water-cooled cooling tower cannot be well adapted to the power of the liquid-cooled cabinet in the computer room. Utility Model Content

[0022] To facilitate understanding of the present invention, a more comprehensive description will be provided below with reference to the accompanying drawings. It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element and integrated therewith, or there may be an intermediate element.

The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the relevant listed items.

[0024] Please refer to Figures 1 to 3 , provides a liquid-cooled computing power system, the liquid-cooled computing power system including a liquid-cooled cabinet a1, a CDU unit b1, a circulating pump b2, a temperature sensor, and a dry cooler c1. The liquid-cooled cabinet a1 is provided with electronic components to be cooled. The liquid outlet of the CDU unit b1 is connected to the liquid inlet of the liquid-cooled cabinet a1, the liquid inlet of the CDU unit b1 is connected to the liquid outlet of the liquid-cooled cabinet a1, and the liquid inlet and liquid outlet of the dry cooler c1 are respectively connected to the CDU unit b1;

[0025] Liquid-cooled cabinet a1 sequentially inputs coolant into dry cooler c1 through its liquid outlet, the liquid inlet of CDU unit b1, CDU unit b1, and the liquid inlet of dry cooler c1. Dry cooler c1 then exchanges heat with the input coolant. Dry cooler c1 then inputs the heat-exchanged coolant into the liquid cooler through its liquid outlet, CDU unit b1, the liquid outlet of CDU unit b1, and the liquid inlet of liquid-cooled cabinet a1.

[0026] The output and input ends of the circulation pump b2 are respectively connected to the liquid inlet and outlet ends of the liquid cooling cabinet a1. The circulation pump b2 is connected to the temperature sensor signal. The temperature sensor detects the temperature of the coolant. The circulation pump b2 adjusts the flow output by the output end according to the temperature detected by the temperature sensor.

[0027] The electronic components to be cooled include electronic components such as a memory bar, a CPU, and a motherboard, or a server a2 composed of these electronic components.

[0028] The present invention can avoid water resource consumption through the CDU unit b1. At the same time, through the cooperation of the CDU unit b1, the circulating pump b2, the dry cooler c1 and the temperature sensor, on the one hand, the power of the liquid-cooled cabinet a1 in the computer room a3 can be adapted by changing the coolant flow input to the liquid-cooled cabinet a1 to adapt to the power changes of the liquid-cooled cabinet; on the other hand, since it can adapt to the power of the liquid-cooled cabinet a1 in the computer room a3, the overall energy efficiency of the dry cooler c1 is greatly improved; furthermore, the present invention can operate under extreme temperature conditions, and can maintain a stable heat dissipation effect in both high and low temperature environments, and is not affected by ambient humidity. At the same time, since the electronic equipment is enclosed in liquid, the impact of dust and other pollutants on the equipment is reduced. Therefore, the present invention can meet the needs of various places for edge computing power.

[0029] Please refer to Figure 1 In a preferred embodiment, circulating pump b2 is a variable frequency pump located between the liquid cooling cabinet a1 and the CDU unit b1. The output of circulating pump b2 is connected to the liquid inlet of the liquid cooling cabinet a1, and the input of circulating pump b2 is connected to the liquid outlet of the CDU unit b1. The circulating pump b2 and the liquid cooling cabinet a1 can be connected directly or indirectly through other means; in this embodiment, a direct connection is used.

[0030] The structure of the variable frequency pump is an existing technology. The variable frequency pump adjusts the flow of coolant input to the liquid cooling cabinet a1 by adjusting the speed. The use of the variable frequency pump to achieve coolant flow control can save equipment costs.

[0031] In a preferred embodiment, a circulation pump b2 is provided on the CDU unit b1. Further, the circulation pump b2 is provided inside the CDU unit b1 and is integrated with the CDU unit b1. The temperature sensor includes a first sensor, a second sensor and a controller. The first sensor and the second sensor respectively detect the coolant temperature of the input and output liquid cooling cabinet a1. A variable frequency fan is also provided outside the dry cooler c1. The variable frequency fan, the circulation pump b2, the first sensor, the second sensor and the controller are signal-connected.

[0032] The first and second sensors respectively detect the first and second temperatures of the coolant entering and exiting liquid-cooled cabinet a1. The controller controls circulating pump b2 based on the temperature difference between the first and second temperatures. The controller also controls the speed of the variable-frequency fan (not shown) based on the second temperature value. For example, in some embodiments, the controller sets a set value for the temperature difference. If the difference between the first and second temperatures exceeds the set value, the circulating pump flow rate increases; if the temperature difference is less than the set value, the circulating pump flow rate decreases. When controlling the variable-frequency fan, a higher second temperature value increases the speed of the variable-frequency fan, while a lower second temperature value decreases the speed of the variable-frequency fan. An increase in the flow rate of coolant pumped by circulating pump b2 enhances the cooling capacity of the liquid-cooled computing power system per unit time. A decrease in the flow rate of coolant pumped by circulating pump b2 reduces the cooling capacity of the liquid-cooled computing power system per unit time. This system can adapt to liquid-cooled cabinets a1 of different power sizes or liquid-cooled cabinets a1 in different states. Increasing the speed of the variable-frequency fan increases the heat dissipation capacity of the dry cooler c1; decreasing the speed of the variable-frequency fan reduces power consumption. The circulation pump B2 is frequency-controlled according to the temperature difference between the inlet and outlet liquids, and the dry cooler C1 fan is frequency-controlled according to the outlet liquid temperature, which greatly reduces the power consumption of the entire system.

[0033] Please refer to Figure 1 In a preferred embodiment, the liquid outlet of the liquid-cooling cabinet a1 is connected to the liquid inlet of the CDU unit b1 via a pipe, the CDU unit b1 is connected to the liquid inlet of the dry cooler c1 via a pipe, the liquid outlet of the dry cooler c1 is connected to the CDU unit b1 via a pipe, and the liquid outlet of the CDU unit b1 is connected to the liquid inlet of the liquid-cooling cabinet a1 via a pipe.

[0034] Furthermore, the liquid outlet and liquid inlet of the dry cooler c1 are C liquid outlet c6 and C liquid inlet c5, respectively. C liquid outlet c6 and C liquid inlet c5 are connected to the CDU unit b1 through C liquid outlet pipe c3 and C liquid inlet pipe c4, respectively. The liquid outlet of the CDU unit b1 is connected to the liquid inlet of the liquid-cooling cabinet a1 through B liquid outlet pipe b4, and the liquid inlet of the CDU unit b1 is connected to the liquid outlet of the liquid-cooling cabinet a1 through B liquid inlet pipe b5.

[0035] Liquid cooling cabinet a1, CDU unit b1 and dry cooler c1 can be prefabricated in the factory, and only the pipelines need to be connected on site.

[0036] In a preferred embodiment, the liquid-cooled computing power system is further provided with a controller (not shown) and a solenoid valve c2. The solenoid valve c2 and the circulation pump b2 are both connected to the controller signal. The input and output ends of the solenoid valve c2 are respectively connected to the liquid outlet end of the dry cooler c1 and the CDU unit b1.

[0037] Solenoid valve C2 controls the connection and disconnection between the liquid outlet of dry cooler C1 and CDU unit B1. When solenoid valve C2 is open, dry cooler C1 delivers heat-exchanged coolant to CDU unit B1. A controller controls the opening and closing of solenoid valve C2 and circulating pump B2, respectively. To prevent system shutdown and the coolant in dry cooler C1 from flowing back into liquid-cooled cabinet A1, solenoid valve C2 is installed at the liquid outlet of dry cooler C1. When circulating pump B2 is turned off, solenoid valve C2 immediately closes.

[0038] Liquid-cooled dry cooler C1 (i.e. dry cooler) plays an important role in data centers, industrial cooling and other fields. Its role is mainly reflected in the following aspects:

[0039] 1. Efficient Heat Dissipation. 1. The liquid-cooled dry cooler C1 operates without direct water consumption. Instead, it cools the coolant (such as fluorinated liquid) through the tubes, while natural air flows outside the tubes to cool the coolant, lowering its temperature and achieving the desired cooling effect. 2. Utilizing the low freezing point and high thermal conductivity of refrigerants like coolant, the liquid-cooled dry cooler C1 efficiently exchanges heat with the cold outdoor air, dissipating heat into the environment.

[0040] 2. Energy saving and consumption reduction. 1. Liquid-cooled dry coolers (C1) utilize natural cooling sources. When the outdoor temperature is low, they can fully utilize natural cooling sources for cooling, reducing or replacing compressor cooling, thereby significantly reducing energy consumption. 2. Modern liquid-cooled dry cooler (C1) systems are typically equipped with a microcomputer control system that can automatically adjust the operating mode based on the temperature difference between the coolant temperature and the room temperature (A3), maximizing energy savings. For example, when the temperature difference reaches 7°C, natural cooling sources can be partially utilized; when the temperature difference reaches above 14°C, the dry cooler (C1) can completely replace compressor cooling.

[0041] 3. Environmentally Friendly. 1. Since the Liquid-Cooled Dry Cooler C1 does not directly consume water during operation, it helps reduce water demand and consumption in data centers and other locations. 2. Through its highly efficient and energy-saving cooling method, the Liquid-Cooled Dry Cooler C1 helps reduce energy consumption and carbon emissions in data centers, which is of great significance to environmental protection and sustainable development.

[0042] In the prior art, when liquid-cooled dry coolers c1 or cooling towers are combined with CDU units b1, system shutdowns are common, with coolant in dry cooler c1 backflowing into liquid-cooled cabinet a1. The present invention effectively addresses this issue by combining a controller, circulating pump b2, solenoid valve c2, and CDU units b1.

[0043] Please refer to Figures 1 to 3In a preferred embodiment, multiple CDU units b1 are interconnected via a parallelizer b3. Parallelizer b3 can utilize conventional pipes, connectors, or a combination thereof to interconnect the CDU units b1. Multiple liquid-cooled CDUs are connected via piping, providing backup and ensuring trouble-free system operation.

[0044] Please refer to Figures 1 to 3 In a preferred embodiment, the liquid-cooled computing power system is further provided with a machine room a3, in which a plurality of liquid-cooled cabinets a1 and a plurality of CDU units b1 are provided. The CDU units b1 are provided corresponding to the liquid-cooled cabinets a1, and the CDU units b1 are interconnected through the parallel connector b3.

[0045] Please refer to Figures 2 to 3 In a preferred embodiment, computer room a3 is equipped with an electrical control box a5 and a wiring rack a4. Wiring rack a4 is mounted on the liquid cooling cabinet a1 and the CDU b1. The electrical control box a5 is electrically connected to the liquid cooling cabinet a1 and the CDU b1 via wires routed through wiring rack a4. The wiring rack a4 facilitates wiring and enhances the aesthetics of computer room a3.

[0046] Please refer to Figures 1 to 3 In a preferred embodiment, the circulating pump is located within the CDU unit b1. A water distributor (not shown) and a water collector (not shown) are provided within the CDU unit b1. The water distributor and the water collector are conventional. The liquid outlet of the CDU unit b1 is connected to the liquid inlet of the liquid-cooling cabinet a1 via the water distributor, and the liquid inlet of the CDU unit b1 is connected to the liquid outlet of the liquid-cooling cabinet a1 via the water collector. The water distributor distributes the coolant output by the CDU unit b1 to each liquid-cooling cabinet a1, and then returns the collected coolant to the CDU unit b1 for cooling. The CDU unit b1 has a water distributor, and the CDU unit b1 can be connected to one, two, or more liquid-cooling cabinets a1 as needed. This embodiment is a one-to-two or one-to-three CDU unit b1, that is, the CDU unit b1 can be connected to multiple liquid-cooling cabinets. A single CDU unit b1 can simultaneously supply the cooling needs of multiple liquid cooling devices. This design improves the flexibility and efficiency of the liquid cooling system, reduces the number of devices and pipelines, and helps simplify system architecture and management. The main advantages of this solution are:

[0047] 1. Space saving: Connecting multiple liquid cooling cabinets a1 through a CDU unit b1 can reduce the number of devices in the system and the space occupied, thereby improving the device density and space utilization of the computing system.

[0048] 2. Reduce costs: Reducing the number of liquid-cooled CDU units (B1) can reduce system deployment and maintenance costs and improve overall economic benefits.

[0049] 3. Convenient management: When multiple liquid cooling cabinets a1 need to be run simultaneously, the one-to-many design can simplify system management, reduce the number of equipment interfaces and pipeline connections, and improve management efficiency.

[0050] 4. Flexibility: The one-to-two or one-to-three design provides greater flexibility, adapting to liquid cooling systems of different sizes and allowing for flexible expansion and reduction of connected devices based on actual needs.

[0051] In general, a one-to-two or one-to-three liquid-cooled CDU b1 system design helps optimize the layout and management of the liquid cooling system, improving system efficiency and reliability. By maximizing the cooling capacity of the CDU b1, it can meet the cooling needs of multiple liquid cooling devices, providing an efficient heat dissipation solution for the data center.

[0052] Please refer to Figures 1 to 3 During operation, liquid-cooled cabinet a1, its server a2, CDU b1, and dry cooler c1 begin operating. Driven by circulating pump b2, liquid-cooled cabinet a1 sequentially supplies coolant to dry cooler c1 through its liquid outlet, the liquid inlet of CDU b1, and the CDU b1 and liquid inlet of dry cooler c1. Dry cooler c1 then exchanges heat with the incoming coolant. Dry cooler c1 then supplies the heat-exchanged coolant to the liquid cooler through its liquid outlet, CDU b1, the liquid outlet of CDU b1, and the liquid inlet of liquid-cooled cabinet a1, thus achieving heat exchange. CDU b1 also distributes the coolant.
