Description

Technical Field

[0001] The present invention relates to the field of submarine data center refrigeration technology, and in particular to an air-liquid homogenous system based on a submarine prefabricated modular data center and an implementation method thereof. Background Art

[0002] In the digital age, information technologies such as cloud computing, 5G, big data, and artificial intelligence are rapidly developing. Computing power has become a new productivity driver in the digital economy. This increase in computing power has led to a rapid increase in chip power consumption, making traditional air cooling difficult to meet the heat dissipation requirements of these high-power chips. Liquid cooling, however, utilizes liquids with high specific heat capacity as a refrigerant. Its cooling capacity is 1,000-3,000 times greater than that of air, and its thermal conductivity is 25 times greater. This effectively addresses the heat dissipation challenges faced by high-power chips, and the deployment of liquid cooling systems in intelligent computing centers to meet these requirements has become a trend.

[0003] Existing liquid cooling systems primarily use cold plate cooling. This involves placing liquid heat sinks close to the server's CPU and GPU. Low-temperature fluid within a plate heat exchanger removes heat from the server chips. However, due to the high heat dissipation of servers in intelligent computing centers, air cooling is still required to handle the remaining heat, beyond that provided by cold plate cooling.

[0004] With the construction of submarine prefabricated modular data centers, cooling of submarine prefabricated modular data centers has become a technical problem that needs to be solved urgently. If traditional cold plate liquid cooling cabins are used for cooling, two sets of cold sources need to be deployed at the same time, which is costly and difficult to deploy due to the limited space in the cabins. It is difficult to operate and difficult to achieve.

[0005] Therefore, how to use seawater as a cooling source to solve the traditional reliance on cooling towers or other outdoor cooling sources, save space, realize the cooling of submarine prefabricated modular data centers, use the same cooling source for liquid cooling and air cooling, and at the same time achieve the goal of reducing cooling costs is a technical problem that needs to be solved urgently. Summary of the Invention

[0020] Preferably, the system further includes a controller and a cabin temperature sensor arranged inside the submarine prefabricated modular data center cabin, and the controller is electrically connected to the primary side water supply temperature sensor, electric valve 1, electric valve 2, compressor and cabin temperature sensor respectively.

[0021] A method for achieving air-liquid homogenization based on a submarine prefabricated modular data center is described. The method is to place the prefabricated modular data center on the seabed, and the cold plate liquid cooling terminal and the air-cooled air conditioning terminal in the cabin use the same cooling source; the details are as follows:

[0022] During cold plate liquid cooling heat exchange, the primary side is connected to seawater through seawater inlet pipe 1 and seawater inlet pipe 2, and the secondary side is connected to the cold plate liquid cooling cabinet. Specifically, seawater inlet pipe 1 and seawater inlet pipe 2 introduce seawater into the primary side water supply ring pipe through the primary side circulating water pump. The primary side water supply ring pipe sends the seawater to the cooling distribution unit CDU through the primary side water supply branch pipe 3 for heat exchange. The cold plate liquid cooling cabinet is then cooled through the secondary side water supply pipe. The water is then circulated to the sea through the secondary side return pipe, the cooling distribution unit CDU, the primary side return branch pipe 3, the primary side return ring pipe, and the outlet pipe 1 and outlet pipe 2 in sequence.

[0023] During heat exchange at the air-cooled air conditioner terminal, different refrigeration cycle paths are selected according to the temperature of the primary side water supply branch pipe 1 detected by the primary side water supply temperature sensor and the temperature inside the cabin detected by the cabin temperature sensor.

[0024] Preferably, when the primary-side water supply temperature sensor detects that the temperature of the primary-side water supply branch pipe 1 is higher than 18°C, the controller automatically opens the electric valve 2, closes the electric valve 1, starts the compressor, and the seawater inlet pipe 1 and the seawater inlet pipe 2 introduce seawater into the primary-side water supply ring pipe through the primary-side circulating water pump. The primary-side water supply ring pipe exchanges heat with the water side of the water-fluorine heat exchanger through the primary-side water supply branch pipe 2, and the Freon side of the water-fluorine heat exchanger exchanges heat with the evaporator of the dual-cold-source terminal air conditioner through the refrigerant liquid pipe of the dual-cold-source terminal air conditioner, thus completing the entire refrigeration cycle process of compressor → water-fluorine heat exchanger → throttle valve → evaporator of the dual-cold-source terminal air conditioner → compressor, thereby realizing cooling of the other cabin and bearing the remaining heat outside the cold plate liquid cooling;

[0025] When the temperature sensor in the cabin detects that the temperature in the cabin is greater than the set upper temperature threshold, the controller manually opens the second electric valve, closes the first electric valve, starts the compressor, and the seawater inlet pipes one and two introduce seawater into the primary water supply ring pipe through the primary circulating water pump. The primary water supply ring pipe exchanges heat with the water side of the water-fluorine heat exchanger through the primary water supply branch pipe two. The Freon side of the water-fluorine heat exchanger exchanges heat with the evaporator of the dual-cold source terminal air conditioner through the refrigerant liquid pipe of the dual-cold source terminal air conditioner, completing the entire refrigeration cycle process of compressor → water-fluorine heat exchanger → throttle valve → evaporator of the dual-cold source terminal air conditioner → compressor, thereby cooling the cabin and assuming the remaining heat outside the cold plate liquid cooling. The value range of the upper temperature threshold is 25-30°C, preferably 28°C.

[0026] When the temperature sensor inside the cabin detects that the temperature inside the cabin is lower than the set lower temperature threshold, automatic control is performed according to the primary side water supply temperature sensor; wherein the value range of the lower temperature threshold is 18-25°C, preferably 22°C.

[0027] The air-liquid homogenization system and implementation method based on the submarine prefabricated modular data center of the present invention have the following advantages:

[0028] (1) This invention places a prefabricated modular data center on the seabed. The cold plate liquid cooling terminal and the air-cooled air conditioning terminal in the cabin use the same cooling source, solving the problem of traditional cold plate liquid cooling cabins requiring the simultaneous deployment of two cooling sources. By fully utilizing the seawater cooling source, it not only saves cooling costs but also reduces PUE (total data center energy consumption divided by IT equipment energy consumption).

[0029] (2) When it is detected that the temperature of the primary side water supply pipe is not higher than 18°C, the primary side supply and return water loop pipe is directly connected to the heat exchange coil of the dual cold source terminal air conditioner without passing through the water-fluorine heat exchanger; when it is detected that the temperature of the primary side water supply pipe is higher than 18°C, the primary side supply and return water loop pipe and the refrigerant liquid pipe of the dual cold source terminal air conditioner are heat exchanged through the water-fluorine heat exchanger; when it is detected that the temperature in the cabin is higher than 28°C, the controller is manually controlled to realize the heat exchange between the primary side supply and return water loop pipe and the refrigerant liquid pipe of the dual cold source terminal air conditioner through the water-fluorine heat exchanger; when it is detected that the temperature in the cabin is lower than 22°C, the controller is manually controlled to make the entire system automatically controlled according to the detected temperature of the primary side water supply pipe; it can be seen that the present invention can select different cooling paths according to different temperatures, which not only achieves the purpose of cooling the submarine prefabricated modular data center, but also ensures energy saving, avoids waste of cold sources, saves costs, and achieves the goals of energy saving, safety and reliability.

The method is to place the prefabricated modular data center on the seabed, and the cold plate liquid cooling terminal and the air-cooled air conditioning terminal in the cabin use the same cold source; the details are as follows:

[0050] Mode 1: During cold plate liquid cooling heat exchange, the primary side is connected to seawater via seawater inlet pipe 1 21 and seawater inlet pipe 2 22 , and the secondary side is connected to the cold plate liquid cooling cabinet 10 . Specifically, seawater inlet pipe 1 21 and seawater inlet pipe 2 22 introduce seawater into the primary side water supply ring pipe 2 via the primary side circulating water pump 1 . The primary side water supply ring pipe 2 delivers the seawater to the cold distribution unit CDU 8 via the primary side water supply branch pipe 3 25 for heat exchange.

The primary-side water supply ring pipe 2 exchanges heat with the water side of the water-fluorine heat exchanger 9 through the primary-side water supply branch pipe 2 24. The Freon side of the water-fluorine heat exchanger 9 exchanges heat with the evaporator 14 of the dual-cold-source terminal air conditioner through the refrigerant liquid pipe 11 of the dual-cold-source terminal air conditioner, thus completing the entire refrigeration cycle process of compressor 12 → water-fluorine heat exchanger 9 → throttle valve 13 → evaporator 14 of the dual-cold-source terminal air conditioner → compressor 12, thereby realizing cooling of the other cabin and bearing the remaining heat outside the cold plate liquid cooling.

The seawater inlet pipe 1 21 and the seawater inlet pipe 2 22 introduce seawater into the primary water supply ring pipe 2 through the primary circulating water pump 1. The primary water supply ring pipe 2 exchanges heat with the water side of the water-fluorine heat exchanger 9 through the primary water supply branch pipe 2 24.

The method for realizing air-liquid homogenization based on submarine prefabricated modular data center according to claim 9, characterized in that: When the primary side water supply temperature sensor detects that the temperature of the primary side water supply branch pipe 1 is higher than 18°C, the controller automatically opens the electric valve 2, closes the electric valve 1, starts the compressor, and the seawater inlet pipe 1 and the seawater inlet pipe 2 introduce seawater into the primary side water supply ring pipe through the primary side circulating water pump. The primary side water supply ring pipe exchanges heat with the water side of the water-fluorine heat exchanger through the primary side water supply branch pipe 2. The Freon side of the water-fluorine heat exchanger exchanges heat with the evaporator of the dual-cold source terminal air conditioner through the refrigerant liquid pipe of the dual-cold source terminal air conditioner, completing the entire refrigeration cycle process of compressor → water-fluorine heat exchanger → throttle valve → evaporator of the dual-cold source terminal air conditioner → compressor, realizing cooling of the other cabin and bearing the remaining heat outside the cold plate liquid cooling; When the temperature sensor in the cabin detects that the temperature inside the cabin is greater than the set upper temperature threshold, the controller manually opens electric valve 2, closes electric valve 1, and starts the compressor. Seawater inlet pipe 1 and seawater inlet pipe 2 introduce seawater into the primary water supply ring pipe through the primary circulating water pump. The primary water supply ring pipe exchanges heat with the water side of the water-fluorine heat exchanger through the primary water supply branch pipe 2. The Freon side of the water-fluorine heat exchanger exchanges heat with the evaporator of the dual-cold source terminal air conditioner through the refrigerant liquid pipe of the dual-cold source terminal air conditioner, completing the entire refrigeration cycle process of compressor → water-fluorine heat exchanger → throttle valve → evaporator of the dual-cold source terminal air conditioner → compressor, realizing cooling of the cabin and bearing the remaining heat outside the cold plate liquid cooling. Among them, the value range of the upper temperature threshold is 25-30℃; When the temperature sensor inside the cabin detects that the temperature inside the cabin is lower than the set lower temperature threshold, automatic control is performed according to the primary side water supply temperature sensor; the value range of the lower temperature threshold is 18-25℃.
