To address this, technologies are placing data centers on the seabed, utilizing seawater as a natural cooling source to cool servers and reduce energy consumption. However, seawater can severely corrode and contaminate data centers, increasing the frequency of equipment maintenance.

[0003] Existing methods for seabed maintenance primarily involve sinking or surfacing. The sinking method involves underwater inspection and cleaning by divers, but this presents challenges such as limited operating space, difficulty accessing the data center, and significant risks.

[0037] To make the objectives, technical solutions, and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear herein are based solely on the accompanying drawings and are not intended to limit the present invention.

[0038] The sealed connection structure of the cabin-corridor provided by the present invention can facilitate the maintenance of equipment such as servers in the submarine data cabin 2, while effectively improving the corrosion resistance of the data cabin 2 and the submarine corridor 1.

[0039] In one embodiment of the present invention, Figures 1 to 4 As shown, the sealed connection structure of the cabin corridor includes a submarine corridor 1 and several data cabins 2. The submarine corridor 1 is formed into an integrated submarine pipe section 11 and a sea surface pipe section 12, and the submarine pipe section 11 is formed with several corridor docking parts 121. A cabin docking part 21 is formed at the end of each data cabin 2, and the cabin docking part 21 and the corridor docking part 121 are sealed and docked through a sealing joint 22; wherein the sealing joint 22 is located on the inner wall surface of the submarine pipe section 11, the through hole wall surface of the submarine pipe section 11, the outer wall surface of the submarine pipe section 11 and / or the end wall surface of the data cabin 2. The outer surface of the sealing joint 22 is provided with an anti-corrosion layer to improve the corrosion resistance of the sealing joint 22 and extend the service life of the sealing joint 22.

[0040] According to the sealed connection structure of the cabin corridor of this embodiment, the sea surface pipe section 12 is installed on land (such as the coast or island reef), and the submarine pipe section 11 extends from the land to the seabed, and the submarine pipe section 11 is in a sealed bottom state away from the bottom of the sea surface pipe section 12; at the same time, the cabin docking part 21 and the corridor docking part 121 are docked, so that the data cabin 2 and the submarine corridor 1 are docked to form a submarine data center. The internal passage of the submarine corridor 1 can provide technicians with a channel to enter and exit the submarine data cabin 2, so as to facilitate technicians to perform daily maintenance on servers and other equipment in the submarine data cabin 2.

[0041] The sealed connection between the data cube 2 and the submarine corridor 1 is achieved through the sealing joint 22, and an anti-corrosion layer is provided on the outer surface of the sealing joint 22 to improve the corrosion resistance of the sealing joint 22 in the seawater environment. Therefore, when the data cube 2 is placed in seawater for a long time, the docking position between the data cube 2 and the submarine corridor 1 can withstand the long-term erosion of seawater without destroying its sealing performance, thereby effectively preventing seawater from entering the interior of the submarine corridor 1 through the gap at the docking position, effectively improving the service life of the submarine data center in the seawater environment, and reducing the maintenance frequency of the data center by technicians.

[0042] In addition, since the sealing joint 22 can be arranged on the inner wall surface of the submarine pipe section 11, the through-hole wall surface of the submarine pipe section 11, the outer wall surface of the submarine pipe section 11 and / or the end of the cabin docking part 21, when the data cabin 2 and the submarine corridor 1 are docked, they can be combined at one or more positions to further improve the sealing performance of the docking position, thereby further improving the service life of the submarine data center.

[0043] It should be noted that the anti-corrosion layer is preferably a titanium coating 23, which utilizes the high corrosion resistance of titanium metal to improve the corrosion resistance of the sealing joint 22. Specifically, the sealing joint 22 can be made of titanium metal to ensure the service life of the sealing joint 22. Alternatively, the flange-type sealing joint 22 can be made by coating the outer wall of the titanium layer, but the titanium layer must completely coat the outer wall of the sealing joint 22 to ensure the corrosion resistance of the sealing joint 22 in a seawater environment.

[0044] It should also be noted that when the arrangement positions of the sealing joints 22 are different, the submarine corridor 1 is formed with corridor docking parts 121 at different positions to ensure the sealing performance of the sealing joints 22 when docking at various positions.

[0045] When the corridor docking portion 121 is a through hole formed on the side wall of the submarine pipe section 11 and the cabin docking portion 21 is the end wall of the data cabin 2, the sealing joint 22 can be arranged in the following ways:

[0046] The first arrangement, such as Figure 5As shown, the sealing joint 22 is located on the inner wall of the subsea pipe section 11, the shelter docking portion 21 is inserted into the corridor docking portion 121, and the bottom surface of the shelter docking portion 21 is sealed to the end wall of the sealing joint 22 via a seal. Furthermore, when the data shelter 2 and the subsea pipe section 11 are arranged, the seal can be used to seal the connection gap between the shelter docking portion 21 and the end wall of the sealing joint 22, thereby achieving a sealed connection between the data shelter 2 and the subsea pipe section 11.

[0047] The second arrangement, such as Figure 6 As shown, the sealing joint 22 is located on the through-hole wall of the submarine pipe section 11. The shelter docking portion 21 is inserted into the corridor docking portion 121. The side of the shelter docking portion 21 is sealed with the inner wall of the sealing joint 22 via a sealing member. When the shelter docking portion 21 is inserted into the corridor docking portion 121, the sealing member in the sealing joint 22 can be used to seal the connection gap between the side of the shelter docking portion 21 and the inner wall of the corridor docking portion 121, thereby achieving a sealed connection between the data shelter 2 and the submarine corridor 1.

[0048] When the corridor docking portion 121 is the outer wall of the submarine pipe section 11 and the cabin docking portion 21 is the end wall of the data cabin 2, the sealing joint 22 can be arranged in the following ways:

[0049] The third arrangement is as follows: Figure 7 As shown, the sealing joint 22 is located on the outer wall of the submarine pipe section 11, and the shelter docking portion 21 is fixedly connected to the outer wall of the submarine pipe section 11. The shelter docking portion 21 is sealed to the end wall of the sealing joint 22 facing away from the submarine pipe section 11 via a seal. When docking the data shelter 2 and the submarine pipe section 11, the shelter docking portion 21 can be connected to the end wall of the sealing joint 22 facing away from the submarine pipe section 11, and a seal can be arranged on the end wall of the sealing joint 22 facing away from the submarine pipe section 11. The seal can be used to seal the connection gap between the shelter docking portion 21 and the end wall of the sealing joint 22, thereby achieving a sealed docking between the data shelter 2 and the submarine corridor 1.

[0050] The fourth arrangement is as follows: Figure 8 As shown, the sealing joint 22 is located on the end wall of the data cube 2. The end wall of the sealing joint 22 facing the subsea pipe section 11 is sealedly connected to the outer wall of the subsea pipe section 11 via a seal. When docking the data cube 2 and the subsea pipe section 11, the end wall of the sealing joint 22 facing the subsea pipe section 11 can be connected to the outer wall of the subsea pipe section 11, and a seal can be arranged on the end wall of the sealing joint 22 facing the subsea pipe section 11 to achieve a sealed docking between the data cube 2 and the subsea gallery 1.

[0051] Of course, in the fourth arrangement, the sealing joint 22 may also be located on the outer wall surface of the cabin docking portion 21 and sealably abut against the hole wall surface of the corridor docking portion 121 .

[0052] In this embodiment, the sealing joint 22 is preferably arranged in the first arrangement, so that technicians can directly perform maintenance on the sealing joint 22 after entering the data cabin 2 from the corridor inside the submarine pipe section 11.

[0053] Furthermore, in order to further improve the sealing performance when the data cube 2 and the submarine corridor 1 are docked, a sealing layer is provided on the connection surface 221 between the corridor docking part 121 and the cube docking part 21. The sealing layer can further fill the connection gap between the connection surfaces 221 of the corridor docking part 121 and the cube docking part 21, and expand the sealing surface 222 area, so as to ensure that the data cube 2 and the submarine corridor 1 can be completely sealed when docked through the cooperation of the sealing part and the sealing layer, and further ensure the sealing performance of the docking between the data cube 2 and the submarine corridor 1.

[0054] Among them, when the sealing joint 22 is arranged in the first arrangement mode, in order to ensure the docking sealing and docking stability of the data cabin 2 and the submarine corridor, as shown in FIG. Figure 2 、 Figure 5 and Figure 9 As shown, the sealing joint 22 is formed with a connecting surface 221 and a sealing surface 222, and the sealing surface 222 is located inside the connecting surface 221. The connecting surface 221 is detachably connected to the inner side surface of the submarine pipe section 11. The cabin docking part 21 (i.e., the end wall surface of the data cabin 2) is flush with the inner wall surface of the submarine pipe section 11, and the end wall surface of the cabin docking part 21 is detachably connected to the sealing surface 222, so as to ensure the docking sealing between the submarine pipe section 11 and the data cabin 2 while improving the docking stability between the submarine pipe section 11 and the data cabin 2.

[0055] Moreover, since the end wall of the data cube 2 is flush with the inner wall of the submarine pipe section 11 after the data cube 2 is docked with the submarine pipe section 11, technicians can perform maintenance and repairs on the sealing structure of the data cube 2 and the submarine pipe section 11 directly inside the corridor of the submarine pipe section 11, effectively reducing the difficulty of maintaining the sealing structure.

[0056] Specifically, the sealing joint 22 is detachably connected to the corridor docking part 121 and the cabin docking part 21 through fasteners (such as bolts or studs, etc.) to improve the assembly prefabrication rate of the data cabin 2 and the submarine pipe section 11, and facilitate the assembly of the data cabin 2 and the submarine pipe section 11 on land, and then sink the entire data center to the seabed, effectively reducing the difficulty of assembly construction of the data center.

[0057] In some optional embodiments, the data cabin 2 is a metal tube, and the outer wall of the data cabin 2 and the outer wall of the submarine pipe section 11 are compounded with an anti-corrosion layer. The metal tube and the anti-corrosion layer are compounded to form the overall structure of the data cabin 2. The metal tube has excellent plasticity and strength, which can effectively improve the construction efficiency of the cabin; at the same time, the anti-corrosion layer can effectively improve the corrosion resistance of the outer wall of the data cabin 2 in seawater, ensuring that the data cabin 2 can be placed on the seabed for a long time, preventing seawater from corroding the data cabin 2, and further improving the service life of the data center on the seabed.

[0058] Among them, the anti-corrosion layer is a titanium coating 23, and the thickness of the titanium coating 23 is 2mm-3mm. Specifically, the thickness of the titanium coating 23 is preferably 2mm, so as to ensure that a thin titanium coating 23 is formed on the outer wall surface of the data cabin 2 and the outer wall surface of the submarine pipe section 11, while reducing the difficulty of processing the titanium coating 23 and compounding it on the outer wall surface of the steel structure, reducing the loss of the titanium coating 23 during the compounding process, and improving the utilization rate of titanium metal on the outer wall surface of the steel structure.

[0059] In addition, compared with building a titanium alloy shelter, forming a thin titanium coating 23 on the outer wall of a steel shelter can effectively reduce the cost of building the shelter and avoid restrictions on its application.

[0060] Preferably, the titanium coating 23 is coated on the outer wall surface of the data cube 2 and the outer wall surface of the submarine pipe section 11 by laser cladding.

[0061] It should also be noted that the submarine corridor 1 can be made of steel pipes or reinforced concrete immersed pipes. Figure 4 As shown, the cross-section of the submarine corridor 1 is rectangular, allowing technicians to enter the corridor by transport vehicles and providing space for other data center components. The corridor docking portion 121 is a through-hole formed in the side of the submarine pipe section 11. The cabin docking portion 21 is the entrance end of the data cabin 2. During docking, the end of the data cabin 2, equipped with server cabinets, is inserted into the through-hole on the side of the submarine pipe section 11, completing the docking between the cabin and the corridor.

[0062] Accordingly, the present invention further provides an anti-corrosion connection method for connecting a shelter and a corridor. The anti-corrosion connection method is based on any one of the above-mentioned shelter-corridor sealed connection structures, wherein the anti-corrosion connection method comprises the following steps:

[0063] S1. Arrange the submarine corridor 1: Connect the segmented submarine pipe sections 11 and the sea surface pipe sections 12 in sequence to form an integrated submarine corridor 1, and form a walking passage inside the submarine corridor 1 to provide access for technicians and facilitate routine maintenance of the submarine data cabin 2.

[0064] It should be noted that the subsea pipe section 11 and the surface pipe section 12 can be cast in concrete, and the subsea pipe section 11 and the surface pipe section 12 can be connected using cast-in-place concrete to improve the structural strength of the subsea corridor 1. The walking passage inside the subsea corridor 1 is a tunnel-shaped structure, forming a two-way road for technicians to enter and exit the data cabin 2.

[0065] It should also be noted that after the submarine corridor 1 is formed, the submarine corridor 1 can be subjected to a submarine environment simulation test, wherein the submarine environment simulation test includes but is not limited to a simulation test of the temperature, salinity and pressure at the predetermined placement depth of the seabed to verify the performance of the submarine corridor 1 in the predetermined placement environment.

[0066] S2. Forming a titanium-steel composite cabin: A titanium coating 23 is formed on the outer wall of the formed data cabin 2. The thickness of the titanium coating 23 is 2mm-3mm. The titanium coating 23 is combined with the data cabin 2 to form a titanium-steel composite cabin, which improves the corrosion resistance of the data cabin 2 to seawater, ensures that the data cabin 2 and the submarine pipe section 11 can be placed on the seabed for a long time, and effectively increases the service life of the data center on the seabed.

[0067] It should be noted that the thickness of the titanium coating 23 is preferably 2 mm. The titanium coating 23 can be coated on the outer wall of the data cube 2 by laser cladding to form a titanium-steel composite cube. The 2 mm titanium coating 23 can form a thin titanium coating 23 on the outer wall of the data cube 2, thereby reducing the difficulty of composite processing of the titanium coating 23 on the outer wall of the data cube 2, effectively reducing the loss of the titanium coating 23, and improving the utilization rate of the titanium metal.

[0068] It should also be noted that the steel data cabin 2 and the titanium steel data cabin 2 were placed in the seawater environment at the same depth and for the same time (for example, they were placed in the seawater environment at a depth of 3500m in the South China Sea for 243 days). After the two sets of data cabins 2 with different structures were salvaged from the sea, the outer surface of the steel data cabin 2 had been severely corroded, while the outer surface of the titanium steel data cabin 2 did not show any corrosion phenomena such as pitting pits, indicating that the service life of the titanium steel composite data cabin 2 is significantly better than that of the steel data cabin 2.

[0069] S3. Cabin-corridor docking: Arrange several titanium-steel composite cabins on both sides of the submarine pipe section 11 in sequence, and dock the cabin docking portion 21 of the titanium-steel composite cabin with the corridor docking portion 121 of the submarine pipe section 11 through the sealing joint 22, so that the corridor docking portion 121 and the cabin docking portion 21 are tightly abutted by the sealing joint 22, thereby sealing the connection gap between the two and preventing seawater from seeping into the interior of the submarine corridor 1.

[0070] Preferably, the corridor docking portion 121 of the submarine pipe section 11 is a through hole, and the sealing joint 22 is located on the inner wall of the submarine pipe section 11. The shelter docking portion 21 is the end of the data shelter 2 facing the submarine pipe section 11. The shelter-corridor docking is completed by inserting the end of the data shelter 2 into the corridor docking portion 121 of the submarine pipe section 11. The sealing joint 22 uses a seal to seal the connection gap between the end of the data shelter 2 and the end face of the sealing joint 22, ensuring sealing performance during the shelter-corridor docking.

[0071] Specifically, before step S3, the method further includes:

[0072] S31, a titanium coating 23 is composited on the outer surface of the sealing joint 22. The thickness of the titanium coating 23 of the sealing joint 22 is also 2 mm to improve the corrosion resistance of the sealing joint 22 and prevent the sealing joint 22 from being corroded by seawater, which affects the sealing performance between the submarine corridor 1 and the data cabin 2.

[0073] Correspondingly, the present invention also provides an underwater data center, which includes a heat dissipation system, a cabinet, and a sealed connection structure of the cabin corridor as described in any one of the above items. The cabinet and the heat dissipation system are both arranged inside the data cabin 2, and the refrigerant pipeline of the heat dissipation system is connected to the cabinet.

[0074] The underwater data center has all the benefits of the aforementioned sealed connection structure for the shelter corridor, which will not be elaborated here. Furthermore, the internal corridor of submarine corridor 1 provides access for technicians to enter and exit the submarine corridor 1, facilitating routine maintenance of cabinets and cooling systems, and greatly reducing the risk of divers entering the water.

[0075] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
