[0002] With the rapid development of 5G communications, artificial intelligence, and data services, large-scale data computing has become a crucial need and essential requirement across various fields, and data centers bear a significant portion of these data computing tasks. In data center energy consumption, cooling systems account for the vast majority of the additional energy consumption.

[0003] To reduce the energy consumption of data center cooling, related technologies employ a bracket system to fix the condensing system to the top of the data container, placing the condensing system and the data center together on the seabed to utilize seawater as a natural cold source to cool the servers. However, the seabed environment causes severe corrosion and fouling to the data container and condensing system, and marine organisms such as barnacles easily attach to the exterior of the data container and the condensing system pipes, affecting heat exchange between the condensing system and the data container, thus reducing the cooling effect of the data container. Summary of the Invention

[0007] Several data cabins are arranged sequentially outside the seabed section, and each data cabin is docked to the seabed section. The data cabin has a compartment for placing server cabinets inside, and the compartment is connected to the walking passage.

[0008] A heat dissipation system is installed inside the walking passage. The heat dissipation system consists of a cooling section and a cooling section. The cooling section is adapted to be connected to the seawater environment. The cooling section is connected to the server cabinet and the cooling section is connected to the cooling section for heat exchange.

[0009] As an improvement to the above solution, the heat dissipation system includes a first drive pump, a heat exchanger and a second drive pump. The cooling section includes a first cold pipe and a first heat pipe that are connected to the seawater environment. The first drive pump is disposed on the first cold pipe, and the cold seawater inlet of the heat exchanger is connected to the first cold pipe.

[0010] The cooling section includes a second cold pipe and a second heat pipe. The second drive pump is disposed on the second cold pipe. The refrigerant outlet of the heat exchanger is connected to the server cabinet through the second cold pipe, and the refrigerant inlet of the heat exchanger is connected to the server cabinet through the second heat pipe.

[0011] As an improvement to the above solution, the walking channel is formed with an installation groove, the first drive pump, the heat exchanger and the second drive pump are installed in the installation groove, and the cooling section and the cooling section are pre-embedded in the installation groove.

[0012] As an improvement to the above scheme, the fluid flow rate of the cooling section is greater than that of the cooling section.

[0013] As an improvement to the above solution, a spiral tube is provided at the end of the cooling section away from the heat exchanger. The spiral tube is wound around the server cabinet. The outlet of the second cold pipe is connected to the inlet of the spiral tube, and the inlet of the second heat pipe is connected to the outlet of the spiral tube.

[0014] As an improvement to the above solution, a seawater filter is provided between the inlet of the first cold pipe and the first drive pump.

[0015] As an improvement to the above scheme, the sidewall of the seabed section is formed with several container docking interfaces, each data container is sealed and docked with one of the container docking interfaces, and the outer wall of the data container is provided with a titanium cladding.

[0016] As an improvement to the above solution, the inner wall of the seabed section is provided with a sealing joint, the data container is inserted into the container docking interface and sealed with the sealing joint, the outer wall of the sealing joint is provided with a titanium coating, and the data container is a steel pipe.

[0017] As an improvement to the above solution, the thickness of the titanium coating is 2mm-3mm.

[0018] Accordingly, the present invention also provides a method for arranging a subsea data center, the method being based on the corridor-type subsea data center described in any one of the above claims, comprising:

[0019] S1. Arrange the underwater corridor: Connect the segmented surface section and underwater section in sequence to form an integrated underwater corridor, and form a walking passage inside the underwater corridor.

This facilitates technicians' access to and from the data container and allows them to maintain the server cabinets inside the data container, solving the problem of difficult underwater maintenance and repair of existing data centers.

[0026] Meanwhile, by setting the heat dissipation system inside the walking passage and coordinating the cooling section and the cooling extraction section, seawater is used as a cold source to dissipate heat from the server cabinet, reducing the energy consumption of the data center. Furthermore, the heat dissipation system does not need to come into contact with the seawater environment, effectively avoiding corrosion of the heat dissipation system by the seawater environment and preventing marine organisms from attaching to the outside of the pipes in the cooling section, thus ensuring the heat exchange effect between the cooling section and the server cabinet, thereby ensuring the heat dissipation effect of the heat dissipation system on the server cabinet inside the data cabin.

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0035] The corridor-type seabed data center provided by the present invention can facilitate the maintenance of the seabed data container 2 while avoiding corrosion of the heat dissipation system 3 and ensuring the heat dissipation effect of the heat dissipation system 3 on the server cabinet 201.

[0036] In embodiments of the present invention, such as Figures 1 to 3 As shown, the connecting corridor-type subsea data center includes a subsea corridor 1, a heat dissipation system 3, and several data cabins 2. The subsea corridor 1 forms an integral surface section 11 and a seabed section 12, with a connecting walkway 13 between the surface section 11 and the seabed section 12. Several data cabins 2 are arranged sequentially outside the seabed section 12, and each data cabin 2 is connected to the seabed section 12. The data cabin 2 has a compartment 21 for housing server cabinets 201, and the compartment 21 is connected to the walkway 13. The heat dissipation system 3 is located inside the walkway 13 and has a cooling section 32. The cooling section 31 is adapted to communicate with the seawater environment, and the cooling section 32 is connected to the server cabinets 201, with the cooling section 32 and cooling section 31 connected for heat exchange.

[0037] According to the corridor-type submarine data center of this embodiment, by forming an integrated sea surface section 11 and seabed section 12 by connecting the underwater corridor 1, and connecting the walking passage 13 in the underwater corridor 1 with the cabin 21 of the data container 2, a corridor is provided for technicians to enter the underwater data container 2 from the sea surface, which facilitates technicians to enter and exit the data container 2 and maintain the server cabinet 201 in the data container 2, thus solving the problem of difficult maintenance and repair of existing data centers underwater.

[0038] Meanwhile, by setting the heat dissipation system 3 inside the walking passage 13, and through the cooperation of the cooling section 32 and the cooling section 31, the server cabinet 201 is cooled by seawater, reducing the heat dissipation energy consumption of the data center. Furthermore, the heat dissipation system 3 does not need to come into contact with the seawater environment, effectively avoiding corrosion of the heat dissipation system 3 by the seawater environment, and preventing marine organisms from attaching to the outside of the pipes of the cooling section 32, ensuring the heat exchange effect between the cooling section 32 and the server cabinet 201, thereby ensuring the heat dissipation effect of the heat dissipation system 3 on the server cabinet 201 inside the data cabin 2.

[0039] It should be noted that the underwater corridor 1 is preferably formed by concrete casting. The sea surface section 11 of the underwater corridor 1 is located on land above sea level (such as coast or islands and reefs). The bottom of the sea surface section 11 is sealed. The walking passage 13 inside the underwater corridor 1 is a tunnel-shaped structure. The walking passage 13 forms at least a two-way road to allow vehicles to travel back and forth, facilitating technicians to enter and exit to maintain the server and move related equipment.

[0040] Furthermore, the underwater connecting corridor 1 can adopt a segmented structure, so that it can be assembled in sections on land and then launched into the water as a whole after simulating the seawater environment for verification, thereby reducing the overall construction difficulty.

[0041] In one embodiment, the heat dissipation system 3 can be arranged in the following manner to achieve heat dissipation for the data center using seawater as a cold source. For example... Figure 6 and Figure 7 As shown, the heat dissipation system 3 includes a first drive pump 33, a heat exchanger 34, and a second drive pump 35. The cooling section 31 includes a first cold pipe 311 and a first heat pipe 312 connected to the seawater environment. The first drive pump 33 is disposed on the first cold pipe 311, and the cold seawater inlet of the heat exchanger 34 is connected to the first cold pipe 311. The cooling section 32 includes a second cold pipe 321 and a second heat pipe 322. The second drive pump 35 is disposed on the second cold pipe 321. The refrigerant outlet of the heat exchanger 34 is connected to the server cabinet 201 via the second cold pipe 321, and the refrigerant inlet of the heat exchanger 34 is connected to the server cabinet 201 via the second heat pipe 322.

[0042] Using the above arrangement, the first drive pump 33 pumps low-temperature seawater from the first cold pipe 311 into the heat exchanger 34. The seawater exchanges heat with the high-temperature refrigerant in the heat exchanger 34, lowering the refrigerant temperature. The heated seawater is then discharged from the seawater environment through the first heat pipe 312. The low-temperature refrigerant is then sent to the server cabinet 201 via the second drive pump 35 and the second cold pipe 321 to absorb the heat generated by the server cabinet 201, thus dissipating heat from the server cabinet 201. This utilizes seawater as a cold source to cool the data center, reducing its energy consumption, lowering operating costs, and achieving energy conservation and emission reduction.

[0043] The refrigerant in the heat exchanger 34 is preferably a circulating coolant, such as liquid water or ethylene glycol solution. The circulating coolant absorbs the heat from the server cabinet 201 through a cold plate or immersion cooling, and facilitates heat exchange with the low-temperature seawater supplied by the first cold pipe 311.

[0044] As a further improvement to the above embodiments, such as Figure 3As shown, the travel channel 13 has an installation groove 131. The first drive pump 33, heat exchanger 34, and second drive pump 35 are installed in the installation groove 131. The cooling section 31 and the cooling section 32 are pre-embedded in the installation groove 131 to utilize the space of the installation groove 131 to arrange the first drive pump 33, heat exchanger 34, and second drive pump 35, so that the heat dissipation system 3 in the travel channel 13 is neatly arranged, improving the space utilization rate of the heat dissipation system 3 in the travel channel 13. At the same time, pre-embedding the cooling section 31 and the cooling section 32 in the installation groove 131 reduces the length of each section of pipeline exposed in the travel channel 13, further avoiding clutter inside the travel channel 13 and interfering with the maintenance and repair work of technicians on the cooling section 31 and the cooling section 32.

[0045] Among them, such as Figure 7 As shown, the mounting groove 131 has a through hole (not shown in the figure). The inlet of the first cold pipe 311 and the outlet of the first hot pipe 312 are embedded in the through hole through a mechanical seal joint 132 (such as a compression sealing sleeve or a clamp-type waterproof joint) and connected to the external seawater environment. This seals the first cold pipe 311 with the through hole in the bottom wall of the mounting groove 131 and the first hot pipe 312 with the through hole in the bottom wall of the mounting groove 131, preventing seawater from seeping into the walking channel 13 through the through hole in the bottom wall of the first cold pipe 311, the first hot pipe 312 and the mounting groove 131, thus affecting the use of the walking channel 13.

[0046] It should also be noted that a cable tray is formed at the top of the walking channel 13. The cable tray is connected to a wiring tray that extends to the data cabin 2. Data cables and electrical cables are arranged in the cable tray and wiring tray to power the server cabinet 201 and transmit data.

[0047] In this embodiment, the fluid flow rate Q1 of the cooling section 31 is greater than the fluid flow rate Q2 of the cooling section 32 to ensure that the refrigerant in the cooling section 32 can fully exchange heat with the seawater in the cooling section 31, thus ensuring the heat exchange efficiency of the refrigerant and improving the heat exchange efficiency of the refrigerant on the server cabinet 201, and ensuring the heat dissipation effect of the heat dissipation system 3 on the server cabinet 201.

[0048] The flow rate ratio between the fluid flow rate Q1 in the cooling section 31 and the fluid flow rate Q2 in the cooling section 32 is 1.5-3.1. This ensures sufficient cooling of the refrigerant while preventing an increase in the power consumption of the first drive pump 33, and also prevents excessive seawater flow from accelerating the erosion rate of the first cold pipe 311. Preferably, the flow rate ratio between Q1 and Q2 is 2.6. For example, when the pipe diameters of both the cooling section 31 and the cooling section 32 are 40 mm, and the fluid flow rate of the cooling section 31 is 2.5 tons / h, the fluid flow rate of the cooling section 32 is 0.95 tons / h.

[0049] In another embodiment, a spiral tube (not shown in the figure) is provided at the end of the cooling section 32 away from the heat exchanger 34. The spiral tube is wound around the server cabinet 201. The outlet of the second cold pipe 321 is connected to the inlet of the spiral tube, and the inlet of the second heat pipe 322 is connected to the outlet of the spiral tube. By using the spiral tube to wrap around the server cabinet 201, the spiral tube is tightly fitted to the server cabinet 201, increasing the area through which the refrigerant flows through the server cabinet 201, improving the efficiency of the refrigerant in absorbing the heat dissipated by the server cabinet 201, and simultaneously achieving overall heat dissipation of the server cabinet 201, thus preventing localized overheating of the server cabinet 201.

[0050] In this embodiment, the winding tube is preferably an aluminum tube, which is coiled around the back panel of the server rack to absorb the heat emitted by the server rack. The winding distance between the winding tube and the server rack 201 can be adjusted adaptively according to the actual size of the server rack 201, and is not specifically limited here.

[0051] Of course, in other embodiments, when there is an air gap between the winding tube and the server cabinet 201, a forced convection device such as a cooling fan can be added to increase the airflow velocity between the server cabinet 201 and the winding tube, thereby further improving the heat exchange efficiency between the winding tube and the server cabinet 201.

[0052] Furthermore, since seawater contains impurities such as silt, shell fragments, algae, and microplastics, in order to ensure the service life of the first drive pump 33, such as... Figure 6 As shown, a seawater filter 36 is provided between the inlet of the first cold pipe 311 and the first drive pump 33 to filter impurities in the seawater, prevent impurities in the seawater from entering the first drive pump 33 and scratching the internal components of the first drive pump 33, thereby ensuring the stable operation of the first drive pump 33.

[0053] Specifically, the seawater filter 36 can form a two-layer filtration structure. The first layer is a large-particle filter, located at the inlet of the first cold pipe 311, which mainly intercepts and filters large particulate impurities (such as seaweed, plastic, or shell fragments). The large-particle filter can be a bar filter or a basket filter. The second layer is a small-particle filter, located at the inlet of the first drive pump 33, which mainly intercepts and filters small particulate impurities (such as sand or suspended solids). The small-particle filter can be a sand filter or a cartridge filter. Through the two-layer filtration structure, the seawater is filtered to a certain extent, preventing large and small particulate impurities in the seawater from entering the first drive pump 33 and affecting its operation.

[0054] Furthermore, such as Figure 6As shown, a flow meter 37 is arranged on the first cold pipe 311 between the first drive pump 33 and the heat exchanger 34. The flow meter 37 can be used to detect the flow rate of seawater pumped into the first cold pipe 311 by the first drive pump 33 and filtered. When the detection data of the flow meter 37 is less than a certain threshold, it indicates that the impurities filtered by the seawater filter 36 have reached a certain level, or the impurities in the first cold pipe 311 have reached a certain amount of deposition. This can remind technicians to inspect and maintain the seawater filter 36 and / or the first cold pipe 311.

[0055] In one embodiment, such as Figure 2 , Figure 3 and Figure 5 As shown, the sidewall of the seabed section 12 has several container docking interfaces 121. Each data container 2 is sealed and connected to one of the container docking interfaces 121. The outer wall of the data container 2 is provided with a titanium cladding 22, and the data container 2 is a steel pipe. The titanium cladding 22 and the data container 2 are combined to form a titanium-steel composite structure, which improves the corrosion resistance of the data container 2 in the seawater environment, ensures that the data container 2 can be placed on the seabed for a long time, and improves the service life of the data center on the seabed.

[0056] Furthermore, to ensure the airtightness when the modular shelter connects with the connecting corridor, such as Figure 3 and Figure 4 As shown, a sealing joint 23 is provided on the inner wall of the seabed section 12. The data container 2 is inserted into the container docking interface 121 and is sealed to the sealing joint 23. The sealing joint 23 is used to seal the connection gap between the data container 2 and the container docking interface 121 of the seabed section 12, thereby preventing seawater from seeping into the interior of the walking passage 13 from the connection gap between the two and affecting the use of the corridor.

[0057] To prevent the sealing joint 23 from being corroded by seawater during prolonged contact and thus damaging the sealing performance between the seabed corridor and the data container 2, a titanium cladding 22 is provided on the outer wall of the sealing joint 23. The titanium cladding 22 is used to improve the corrosion resistance of the sealing joint 23, prevent the sealing joint 23 from being corroded when in contact with seawater, and further improve the sealing performance between the seabed corridor and the data container 2.

[0058] It should be noted that the sealing joint 23 is located on the inner wall of the subsea section. A sealing ring is arranged on the end wall of the sealing joint 23 facing the docking interface 121. When the data container 2 is inserted into the docking interface 121, the end of the data container 2 can be flush with the inner wall of the subsea section 12. Then, the end of the data container 2 is connected to the sealing joint 23 by fasteners such as bolts or studs. At the same time, the sealing ring seals the connection gap between the end of the data container 2 and the end wall of the sealing joint 23, so as to achieve a sealed connection between the data container 2 and the subsea section 12.

[0059] Specifically, the thickness of the titanium cladding 22 is 2mm-3mm, with 2mm being the preferred thickness. This ensures a thin titanium cladding 22 is formed on the outer wall of the data cabin 2, reducing the processing difficulty of laminating the titanium cladding 22 onto the outer wall and minimizing titanium metal loss during its formation. Furthermore, compared to constructing a titanium alloy cabin, forming a thin titanium cladding 22 on the outer wall of the steel data cabin 2 effectively reduces construction costs and prevents limitations on its application.

[0060] Preferably, the titanium cladding 22 is applied by laser cladding to the outer wall of the data cabin 2 and the outer wall of the sealing joint 23.

[0061] Accordingly, the present invention also provides a method for arranging a subsea data center, which is based on the corridor-type subsea data center described in any of the above embodiments. The method for arranging a subsea data center includes the following steps:

[0062] Step S1: Arrange the underwater corridor 1: Connect the segmented sea surface section 11 and seabed section 12 in sequence to form an integrated underwater corridor 1, and form a walking passage 13 inside the underwater corridor 1 to facilitate technicians to enter and exit the seabed section 12 through the walking passage 13 to maintain the seabed section 12 and the heat dissipation system 3 of the seabed section 12, as well as enter and exit the container to maintain the server cabinet 201.

[0063] It should be noted that both the surface section 11 and the seabed section 12 are constructed of cast concrete. When connecting the segmented surface section 11 and seabed section 12, cast-in-place concrete can be used for connection to improve the structural strength of the seabed corridor 1. The walking passage 13 is a tunnel structure formed inside the seabed corridor 1.

[0064] It should also be noted that after the underwater corridor 1 is formed, an underwater environment simulation test can be conducted on the underwater corridor 1. The underwater environment simulation test includes, but is not limited to, simulation tests of temperature, salinity and pressure at the predetermined placement depth on the seabed, in order to verify the performance of the underwater corridor 1 in the predetermined placement environment.

[0065] Step S2, docking data container 2: Apply a composite titanium cladding 22 to the outer wall of the data container 2, and arrange several data containers 2 sequentially on both sides of the seabed section 12. Seal and dock each data container 2 with the corresponding container docking interface 121 to ensure the connection and sealing between the data container 2 and the seabed connecting corridor 1, while improving the corrosion resistance of the data container 2 in the seawater environment.

[0066] In this embodiment, the titanium cladding 22 can be coated onto the outer wall of the data cabin 2 by laser cladding. The thickness of the titanium cladding 22 is 2mm, so as to form a thin titanium cladding 22 on the outer wall of the data cabin 2, improve the corrosion resistance of the data cabin 2, reduce the construction difficulty of forming the titanium cladding 22 in the data cabin 2, and reduce the material loss of the titanium cladding 22.

[0067] It should also be noted that the number of data cabins 2 arranged on both sides of the seabed section 12 can be determined based on the sum of the length of the seabed section 12, the length of the data cabins 2 on both sides and the width of the seabed connecting corridor 1, the heat generation power of the data cabins 2, and the factors affecting heat dissipation in the seabed environment, so as to ensure the heat dissipation efficiency of the data cabins 2 while increasing the number of data cabins 2 arranged and improving the utilization rate of seawater cold source.

[0068] Step S3, Arrange the heat dissipation system 3: Install the first drive pump 33, heat exchanger 34 and second drive pump 35 inside the travel channel 13 respectively, and pre-embed the pipes of the cooling section 31 and the cooling section 32 in the bottom wall of the travel channel 13 so as to form a seawater circulation loop through the cooling section 31, the first drive pump 33 and the heat exchanger 34, and a refrigerant circulation loop through the cooling section 32, the second drive pump 35 and the heat exchanger 34, so as to realize the heat exchange between seawater and refrigerant in the heat exchanger 34.

[0069] S4. Arrange server cabinet 201: Place server cabinet 201 inside data cabin 2 and connect cooling section 32 to server cabinet 201. Then, heat dissipation system 3 can use seawater as a cold source to dissipate heat from the data center, reduce the heat dissipation energy consumption of the data center, and reduce the operating cost of the data center. At the same time, since the components of heat dissipation system 3 are installed inside the walking passage 13, it is convenient for technicians to maintain heat dissipation system 3.

[0070] S5. Arrange the seabed section 12 at the corresponding arrangement position on the seabed, and arrange the surface section 11 at the corresponding arrangement position on the sea surface. In some feasible embodiments, after clearing a suitable placement area on the seabed, a large ship can be used to transport the data center to the corresponding sea area. Then, a crane ship can be used to lift the seabed section 12 of the data center to the upper part of the corresponding sea area and sink the seabed section 12 to a predetermined seabed depth. The surface section 11 is placed at a land position on the sea surface (such as an island or coast) to facilitate technicians to enter the seabed section 12 via the surface section 11 and maintain the various components of the seabed section 12.

[0071] After the successful construction of this invention, data center operators can directly take a vehicle through the underwater corridor 1 to the data cabin 2 on the seabed section 12 to perform real-time operation and maintenance on the servers in the data cabin 2, thus solving the problem of difficult maintenance and repair when the data center is deployed underwater.

[0072] Meanwhile, the titanium-steel data cabin 2 with its titanium cladding 22 on the outside solves the corrosion problem of ordinary underwater data center shells, and the thinner titanium cladding does not increase costs excessively. The cabin can be prefabricated in the factory and then assembled in sections with the connecting corridor on the construction site before being launched as a whole, reducing construction difficulty.

[0073] The high-efficiency heat dissipation system 3 adjusts the circulation of coolant in the liquid-cooled cabinet and the rate of seawater pumping by the seawater heat exchange device according to the operating power of the servers in the cabin. It effectively utilizes the ocean as a natural cold source and uses only water pumps as a power source, solving the problem of huge energy consumption and high cost of heat dissipation in traditional data centers, and effectively reducing the operating cost of data centers.

[0074] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
