Description

Technical Field

[0001] This invention relates to the field of data center technology, and more specifically to submarine data centers. Background Technology

[0002] Underwater data centers do not consume fresh water; they are cooled using seawater. Underwater phase-change liquid-cooled data centers do not require energy-intensive chillers or air conditioners, saving electricity and not occupying land resources. They are located near developed coastal cities, resulting in low data latency. Underwater phase-change liquid-cooled data centers are characterized by low heat dissipation energy consumption, short construction periods, and flexible layout.

[0003] In existing technologies, underwater data centers typically house servers and power distribution equipment within the same cylindrical tank. A water cooling pipe system is installed on top of the tank, and an integrated protective shield covers and protects it. By submerging the pipes underwater, the water is used to cool the heat-generating equipment inside the tank.

[0004] However, since underwater data centers are located underwater, the tanks must be sealed, which prevents maintenance personnel from directly entering the interior. Therefore, when repairing and maintaining underwater data centers, special engineering vessels such as floating cranes and barges are needed to lift the tanks out of the water before workers can enter the tanks to carry out their work. This process is time-consuming and inefficient. Summary of the Invention

[0005] In view of this, the present invention provides a subsea data center to solve the problems of long construction time and low efficiency in the maintenance and repair of underwater data centers.

[0006] This invention provides a subsea data center, which includes:

[0007] The containment channel extends from the sea to the seabed; the containment channel is equipped with a maintenance channel and a cable channel, and the cable channel is equipped with communication cables;

[0008] A data terminal is located at the bottom of the receiving channel; the data terminal is connected to the relay station on the road via the communication cable;

[0009] The cooling system includes a cooling end and a heat dissipation end; the heat dissipation end is located on the side wall inside the receiving channel and dissipates heat through convection with seawater; the cooling end is located on the data terminal and absorbs the heat from the data terminal.

[0010] Beneficial Effects: By placing the data terminal within the receiving channel, technicians can directly access the data terminal for repair and maintenance through the access channel, eliminating the need for specialized engineering vessels such as floating cranes or barges to lift the entire underwater data center out of the water for maintenance and repair. This simplifies the operation process, shortens construction time, and improves work efficiency. Therefore, this invention significantly improves the maintainability of subsea data centers, enhancing maintenance efficiency and convenience. Furthermore, subsea data centers do not require separate shore stations; they can draw power from nearby sources, resulting in minimal cable loss and effectively improving power utilization efficiency.

[0011] In one alternative implementation, the receiving channel includes:

[0012] A vertical passage extends vertically from the sea into the seabed; the vertical passage includes a maintenance passage and a cable passage.

[0013] A horizontal channel is located at the bottom of the vertical channel and communicates with the vertical channel; the data terminal is placed within the horizontal channel.

[0014] In one alternative implementation, with the vertical channel as the center, a plurality of horizontal channels are evenly distributed radially along the center.

[0015] Beneficial effects: When technicians maintain each data terminal, the distance between the maintenance channel and each data terminal is the same, which shortens the distance the technicians have to travel, makes it easier for them to move around, and improves their work efficiency.

[0016] In one alternative implementation, multiple horizontal channels are stacked vertically.

[0017] Beneficial effects: By adding horizontal channels to the existing structure, the number of data terminals that can be cooled can be increased, thus improving the capacity of the subsea data center. This layout maximizes the number of data terminals per unit volume while allowing for shared vertical channels, reducing system costs. Furthermore, it eliminates the need for separate subsea data centers, saving on construction costs.

[0018] In one alternative implementation, the receiving channel further includes:

[0019] A cooling channel is fitted around the outer periphery of the vertical channel; the cooling system is installed in the cooling channel.

[0020] Beneficial Effects: In practical applications, the cooling system can be fitted to the outer wall of the cooling channel, allowing the hotter cooling fluid in the system to exchange heat with the outer wall of the cooling channel. Heat is then dissipated through the convection between the outer wall of the cooling channel and the seawater, eliminating the need for additional heat dissipation devices. Compared to commonly used air cooling and backplate cooling, which can struggle to support high heat flux density chips (resulting in excessively high volumetric heat flux density in data center spaces), this embodiment, by implementing a cooling system, eliminates the need for additional heat dissipation devices, thereby improving heat exchange efficiency. This easily overcomes the heat dissipation bottlenecks of high-power, high-heat-flux-density chips, high-density servers, and high-power-density server racks, meeting heat dissipation requirements.

[0021] In one alternative implementation, the cooling system includes:

[0022] A cooling component is installed on the data terminal to absorb the heat of the data terminal;

[0023] A condenser assembly is disposed around the inner wall of the cooling channel; the condenser assembly and the cooling assembly are connected through a circulation pipeline.

[0024] Beneficial effects: In actual operation, the cooling components cool the data terminal. The absorbed heat is transferred to the inner wall of the cooling channel through the condensation components, and then dissipated through convection between the inner wall and seawater, thereby improving heat exchange efficiency. At the same time, air conditioning and other related equipment are no longer needed, saving a significant amount of space.

[0025] In one alternative embodiment, the cooling assembly includes a phase change cold plate connected in series and a circulation pump disposed on the circulation pipeline.

[0026] In one optional embodiment, the condensation assembly includes a condenser and a one-way valve connected in series. The condenser is disposed around the inner wall of the cooling channel. The other end of the condenser is connected to the phase change cold plate, and the other end of the one-way valve is connected to the circulation pump through the circulation pipeline.

[0027] In one alternative embodiment, the condenser is provided with an S-shaped channel or a V-shaped channel.

[0028] Beneficial effects: Compared with condensers of ordinary shape, by setting the condenser into an S-shaped or V-shaped channel, the heat exchange area of ​​the condenser can be increased, thereby enhancing condensation and improving the overall cooling efficiency of the system.

[0029] In one alternative embodiment, the condenser has a heat-conducting element on the side near the cooling channel, and the heat-conducting element is in contact with the cooling channel.

[0030] Beneficial effects: By incorporating heat-conducting components, heat can be directly dissipated into the seawater, preventing slow heat dissipation caused by poor adhesion between the condenser and the inner wall of the cooling channel. Furthermore, the addition of heat-conducting components further reduces thermal resistance, improves heat transfer efficiency, and enables timely heat dissipation, preventing heat loss within the cooling channel.

[0031] In one optional embodiment, the condensation assembly further includes:

[0032] A liquid storage tank is connected in series between the check valve and the circulation pump.

[0033] In one optional embodiment, the condensation assembly further includes:

[0034] A bypass pump, one end of which is connected between the condenser and the phase change cold plate, and the other end of which is connected to the liquid storage tank.

[0035] Beneficial effects: By setting up a bypass pump, a small portion of the two-phase fluid can be transported to the storage tank to release heat, causing it to condense into a liquid state and maintain the temperature inside the storage tank. Since temperature and pressure have a one-to-one correspondence during phase change, this indirectly achieves the goal of stabilizing the cooling system pressure.

[0036] In one alternative implementation, the seabed data center further includes:

[0037] The data acquisition module is communicatively connected to the relay station on the road; the data acquisition module is used to collect the operating parameters of the data terminal, the circulating pump, the bypass pump, and the liquid storage tank.

[0038] Beneficial effects: By setting up a data acquisition module, technicians can obtain the overall working status of the system in a timely manner, enabling them to perform timely maintenance on various system components, thereby improving work efficiency. Timely maintenance also extends the service life of each system component.

[0039] In one alternative implementation, the seabed data center further includes:

[0040] A solar power panel is installed on the sea surface; the solar power panel is suitable for covering all horizontal channels.

[0041] Beneficial effects: Since data centers need to draw power from the land-based power grid, the power cables need to be submerged in the seabed, increasing the difficulty of construction and the risk of leakage. Therefore, in addition to powering the underwater data center and avoiding construction and leakage risks, solar power panels can also prevent sunlight from radiating heat to the outer wall of the cooling channel, thereby improving the heat dissipation of the cooling system in the underwater data center.

[0042] In one optional embodiment, the covering portion of the solar power generation panel located above the maintenance passage is detached, and the covering portion has a folded state that exposes the maintenance passage and a closed state that covers the maintenance passage under the action of external force.

[0043] Beneficial effects: To facilitate access to the data terminal for maintenance from the maintenance channel, the solar power panels deployed on the sea surface are foldable. They can be partially folded during maintenance, making it easier to access the maintenance channel without the need for back panel doors or other equipment. This saves a lot of space while generating electricity. Attached Figure Description

[0053] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0055] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0056] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0057] Underwater data centers do not consume fresh water; they are cooled by seawater. Underwater phase-change liquid-cooled data centers do not require energy-intensive chillers or air conditioners, saving electricity and not occupying land resources. They are located near developed coastal cities, resulting in low data latency. Underwater phase-change liquid-cooled data centers feature low heat dissipation energy consumption, short construction cycles, and flexible layouts. In existing technologies, underwater data centers typically house servers and power distribution equipment within a single cylindrical tank, with a water-cooling piping system at the top of the tank, protected by an integrated shield. The pipes are submerged underwater, using water to cool the heat-generating equipment inside the tank. However, because underwater data centers are located underwater, the tanks must be sealed, preventing maintenance personnel from directly entering the interior. Therefore, maintenance and repair of underwater data centers require the use of specialized engineering vessels such as floating cranes and barges to lift the tanks out of the water before personnel can enter, resulting in lengthy and inefficient work.

[0058] In view of this, the present invention provides a subsea data center to solve the problems of long construction time and low efficiency in the maintenance and repair of underwater data centers.

[0059] The following is combined Figures 1 to 6 The following describes embodiments of the present invention.

[0060] According to an embodiment of the present invention, a submarine data center is provided, which includes a housing channel, a data terminal 3 and a cooling system 4.

[0061] Specifically, in this embodiment of the invention, the receiving channel can be a cylindrical structure with a sealed bottom, extending from the seabed. The receiving channel includes a maintenance channel 1 and a cable channel 5, with communication cables installed in the cable channel 5. Of course, this embodiment is merely an example illustrating a specific type of receiving channel, and is not intended to limit its use. Those skilled in the art can modify it according to actual conditions; for example, it could also be an inverted cone or other type, as long as the same technical effect is achieved.

[0062] Furthermore, the data terminal 3 is located at the bottom of the receiving channel, and is connected to the relay station on the road via the communication cable to ensure its normal operation. Further, in this embodiment of the invention, the cooling system 4 is provided with a cooling end and a heat dissipation end. The heat dissipation end is located on the side wall inside the receiving channel, allowing for convection cooling with the seawater. The cooling end is located on the data terminal 3 to absorb its heat.

[0063] With this configuration, by placing the data terminal 3 within the receiving channel, technicians can directly access the data terminal 3 through the inspection channel 1 for repair and maintenance. This eliminates the need for specialized engineering vessels such as floating cranes or barges to lift the entire underwater data center out of the water for maintenance and repair, thus simplifying the operation process, shortening construction time, and improving work efficiency. Therefore, this embodiment of the invention can significantly improve the maintainability of subsea data centers, increasing maintenance efficiency and convenience. Furthermore, the subsea data center does not require a separate shore station; it can draw power from nearby sources, resulting in minimal cable loss and effectively improving power utilization efficiency.

[0064] In one alternative embodiment, such as Figure 2As shown, the accommodating channel includes a vertical channel and a horizontal channel 7. Specifically, in this embodiment of the invention, the vertical channel extends vertically from the seabed into the seabed, and a maintenance channel 1 and a cable channel 5 are provided within the vertical channel. Hereinafter, an example is given of a cylindrical structure for the vertical channel. The vertical channel can be divided into two parts, with one half used for the maintenance channel 1 and the other half used as the cable channel 5. Of course, this embodiment is merely an example of the proportional distribution of the maintenance channel 1 and the cable channel 5, and is not intended to limit the scope. Those skilled in the art can adjust the proportional distribution of the maintenance channel 1 and the cable channel 5 according to actual conditions. For example, if the maintenance channel 1 is considered too narrow during construction, and the cable in the cable channel 5 occupies less space, the radius of the maintenance channel 1 can be appropriately increased, and the radius of the cable channel 5 reduced. The maintenance channel 1 can occupy 3 / 5, and the cable channel 5 can occupy 2 / 5. The goal is to achieve the same technical effect.

[0065] Furthermore, a horizontal channel 7 is located at the bottom of the vertical channel and communicates with it. The horizontal channel 7 is suitable for housing the data terminal 3. In this embodiment of the invention, technicians can adjust the length and number of the horizontal channels 7 according to the actual number of data terminals 3, and can also adjust the setting angle and position of the horizontal channels 7 according to the seabed conditions. For example, one horizontal channel 7 can be set, perpendicular to the vertical channel; two horizontal channels 7 can be set, and the two horizontal channels 7 can be set side by side. To ensure the overall stability of the channel, during construction, the foundation of the horizontal channel 7 can be a gravity foundation, a steel pile foundation, or a suction anchor foundation.

[0066] Specifically, gravity foundations rely on the weight of the foundation and ballast to resist the overturning moment and sliding force generated by the loads from the upper wind turbine and the external environment, thus maintaining the stability of the foundation and the tower structure above it. Gravity foundations have high requirements for geological conditions; when the bearing capacity of the foundation does not meet the requirements, foundation reinforcement is necessary. Gravity foundations are suitable for hard clay, sand, and rock foundations, where the foundation must have sufficient bearing capacity to support the self-weight of the foundation structure, service loads, and wave and water loads. The foundation dimensions are determined based on the bearing capacity of the foundation and the resistance required to resist sliding and overturning. Circular structures with a bottom are called circular caisson structures, while those without a bottom are called cylindrical structures. Before placing a circular structure, a riprap foundation of a certain thickness must be laid on the foundation. This serves two purposes: leveling and dispersing the stress exerted on the foundation by the structure, thereby reducing foundation stress and mitigating uneven settlement.

[0067] For steel pile foundations, they can be implemented in coastal and inland alluvial plain areas. The soil in these areas is often a thick layer of soft soil. When the load of the superstructure is large, such foundations often cannot be directly used as the bearing layer. The low compressibility bearing layer is also very deep. If ordinary pile foundations are used, a pile hammer with a large impact force must be used when driving the piles. Conventional reinforced concrete and prestressed concrete piles will be difficult to adapt. Therefore, steel piles are often chosen to reinforce the foundation.

[0068] Further, in an optional embodiment, with the vertical channel as the center, a plurality of horizontal channels 7 are evenly distributed radially along the center. Specifically, as shown... Figure 3 As shown, five horizontal channels 7 can be set, each horizontal channel 7 being evenly distributed radially along the center of the circle, so that the interval angle between each horizontal channel 7 is the same. At the same time, the evenly distributed horizontal channels 7 can also improve the overall structural strength of the system, thereby ensuring the stability of the system during use.

[0069] With this setup, when technicians maintain each data terminal 3, the distance between the maintenance channel 1 and each data terminal 3 is the same, which shortens the distance the technicians need to travel, makes it easier for them to move around, and improves their work efficiency.

[0070] Furthermore, in an alternative embodiment, such as Figure 6 As shown, multiple horizontal channels 7 are stacked vertically. Specifically, when the number of data terminals 3 is large, the number of servers can be increased according to the actual situation. To ensure the overall stability and structural strength of the system, support components and buffer components can be placed between the stacked horizontal channels 7 to prevent the horizontal channels 7 from breaking. Furthermore, placing buffer components between the support components and the horizontal channels 7 can prevent friction between the horizontal channels 7 and the support components when slight displacement occurs, thereby avoiding wear on the support components and the horizontal channels 7 and extending the overall service life of the system.

[0071] This configuration allows for the addition of horizontal channels 7 to the existing structure, thereby increasing the number of data terminals 3 that can be cooled and improving the capacity of the subsea data center. This layout maximizes the number of data terminals 3 per unit volume while also allowing for the sharing of vertical channels, reducing system costs. Furthermore, it eliminates the need for separate subsea data centers, thus saving on construction costs.

[0072] Furthermore, in an optional embodiment, the receiving channel further includes a cooling channel 2, which is sleeved on the outer periphery of the vertical channel. The cooling system 4 is disposed in the cooling channel 2. The cooling channel 2 can be directly connected to the horizontal channel 7, or a through hole can be opened on the horizontal channel 7 so that the pipe of the cooling system 4 extends into the through hole and is connected to the cooling end in the horizontal channel 7.

[0073] With this configuration, in practical applications, the cooling system 4 can fit snugly against the outer wall of the cooling channel 2, allowing the hotter cooling fluid in the cooling system 4 to exchange heat with the outer wall of the cooling channel 2. Heat is then dissipated through convection between the outer wall of the cooling channel 2 and the seawater, eliminating the need for additional heat dissipation devices. Compared to commonly used air cooling and backplate cooling, which can struggle to support high heat flux density chips (otherwise, the volumetric heat flux density of the data center space would be excessively high), this embodiment, by using cooling system 4, eliminates the need for additional heat dissipation devices, thus improving heat exchange efficiency. This easily overcomes the heat dissipation bottlenecks of high-power, high-heat-flux-density chips, high-density servers, and high-power-density server racks, meeting heat dissipation requirements.

[0074] Furthermore, in an optional embodiment, the cooling system 4 includes a cooling component and a condensation component. Specifically, the cooling component is disposed on the data terminal 3 to absorb heat from the data terminal 3. The cooling component can be a water-cooled device or an oil-cooled device. Of course, this embodiment is merely an example of a specific type of cooling component, but it is not a limitation. Those skilled in the art can make changes according to actual conditions, as long as the same technical effect is achieved.

[0075] The condenser assembly is disposed around the inner wall of the cooling channel 2, and the condenser assembly is connected to the cooling assembly via a circulation pipeline. With this configuration, during actual operation, the cooling assembly cools the data terminal 3, and the absorbed heat is transferred to the inner wall of the cooling channel 2 through the condenser assembly. Heat is then dissipated through convection between the inner wall and the seawater, thereby improving heat exchange efficiency. Simultaneously, air conditioning and related equipment are no longer needed, saving a significant amount of space.

[0076] Further, in an optional embodiment, the cooling assembly includes a phase change cold plate 45 connected in series and a circulation pump 44 disposed on the circulation pipeline. In an optional embodiment, the condensation assembly includes a condenser 43 connected in series and a one-way valve 42, the condenser 43 being disposed around the inner wall of the cooling channel 2. The other end of the condenser 43 is connected to the phase change cold plate 45, and the other end of the one-way valve 42 is connected to the circulation pump 44 through the circulation pipeline. That is, as... Figure 2 As shown, the phase change cold plate 45, condenser 43, one-way valve 42, and circulating pump 44 form a circulation loop.

[0077] Furthermore, in an alternative embodiment, such as Figure 5As shown, the condenser 43 is provided with an S-shaped channel or a V-shaped channel. This configuration, compared to a condenser 43 of a general shape, increases the heat exchange area of ​​the condenser 43 by using an S-shaped or V-shaped channel, thereby enhancing condensation and improving the overall cooling efficiency of the system. Alternatively, the condenser 43 can be configured as a condensing pipe, with the condensing pipe spirally coiled on the inner wall of the cooling channel 2. This embodiment is merely an example illustrating the specific shape of the condenser 43, and is not intended to limit it. Those skilled in the art can modify it according to actual conditions to achieve the same technical effect.

[0078] Furthermore, in an alternative embodiment, such as Figure 4 As shown, the condenser 43 has a heat-conducting element 8 on one side near the cooling channel 2, and the heat-conducting element 8 is in close contact with the cooling channel 2. This arrangement allows heat to be directly dissipated into the seawater by the heat-conducting element 8, preventing slow heat dissipation due to poor contact between the condenser 43 and the inner wall of the cooling channel 2. Furthermore, the heat-conducting element 8 further reduces thermal resistance, improves heat transfer efficiency, and enables timely heat dissipation, preventing heat loss within the cooling channel 2.

[0079] Specifically, in this embodiment of the invention, the heat-conducting component 8 can be made of a heat-conducting metal or a non-metal. The key is to ensure high thermal conductivity and low cost. The heat-conducting component 8 can be a heat-conducting pad, which can be filled between the condenser 43 and the cooling channel 2. It is highly flexible, effectively covering uneven surfaces of components, and has a long service life, which is beneficial for the long-term use of the equipment. The main heat conduction principle is that during equipment use, pressure and temperature increase, causing the heat-conducting pad to soften and creep, thereby increasing the contact area.

[0080] The thermally conductive component 8 can also be thermally conductive adhesive, also known as thermally conductive silicone. Its main material is silicone, a polymer material with added components to aid heat dissipation. It has excellent thermal conductivity and electrical insulation properties, making it the most commonly used thermally conductive material in many electronic devices. Thermally conductive adhesive also has adhesive properties with high bonding strength, as well as impact and vibration resistance, making it widely used.

[0081] Of course, this embodiment is merely an example of the specific type of heat-conducting component 8, but it does not limit the scope of the embodiment. Those skilled in the art can make changes according to the actual situation, as long as the same technical effect can be achieved.

[0082] Further, in an optional embodiment, the condensation assembly further includes a liquid storage tank 41, which is connected in series between the one-way valve 42 and the circulating pump 44. In an optional embodiment, the condensation assembly further includes a bypass pump 46, one end of which is connected between the condenser 43 and the phase change cooling plate 45, and the other end of which is connected to the liquid storage tank 41. With this configuration, by using the bypass pump 46, a small portion of the two-phase fluid can be transported to the liquid storage tank 41 to release heat and condense it into a liquid state, thereby maintaining the internal temperature of the liquid storage tank 41. Since temperature and pressure have a one-to-one correspondence in the phase change state, this indirectly achieves the purpose of stabilizing the pressure of the cooling system 4.

[0083] Furthermore, in an optional embodiment, the subsea data center further includes a data acquisition module, which is communicatively connected to the land-based relay station. The data acquisition module is used to collect operating parameters of the data terminal 3, the circulating pump 44, the bypass pump 46, and the storage tank 41. These operating parameters may include the internal heat source temperature of the server, the PWM and speed of the circulating pump 44 and the bypass pump 46, and the liquid level, temperature, and pressure of the storage tank 41. Of course, this embodiment is merely an example illustrating the specific type of the heat-conducting component 8, and is not intended to limit its application. Those skilled in the art can modify it according to actual conditions, as long as the same technical effect is achieved.

[0084] This configuration, with its data acquisition module, allows technicians to obtain real-time information on the overall system operation, enabling timely maintenance of each component and thus improving work efficiency. Timely maintenance also extends the lifespan of each system component.

[0085] Of course, the data acquisition module can also be connected to a cloud server. The cloud server can communicate with technicians' terminals, such as mobile phones and computers. In this way, technicians can remotely view the specific operating parameters of each device. The data acquisition module can record the changes of operating parameters at various times in a log file. Technicians can then view the specific operating parameters of each device by reviewing the log file, thereby understanding the actual operating status of each device. Simultaneously, the cloud server can share information internally. If a technician is unable to obtain operating parameters or view log files due to environmental or equipment problems, the issue can be relayed to other technicians.

[0086] Furthermore, in this embodiment of the invention, the data acquisition module can be disposed within the horizontal channel 7. The data acquisition module can be fixedly connected within the horizontal channel 7, or it can be detachably disposed within the horizontal channel 7.

[0087] For fixed connections, welding or bonding can be used. For detachable connections, screws and screw holes, clips and slots, or magnetic attraction can be used for fixing.

[0088] The following provides examples of detachable connection methods. For instance, additional fixing plates can be installed around the edges of the data acquisition module. Those skilled in the art can vary the number of fixing plates (1, 2, 3, 4, etc.) according to actual needs. Screw holes are then made on the fixing plates, and another screw hole is made on the horizontal channel 7 at the corresponding position. Screws are then passed through the screw holes on the fixing plates and the screw holes on the horizontal channel 7 in sequence to connect the data acquisition module to the horizontal channel 7. Alternatively, when using a snap-fit ​​and slot method for fixing, additional snap-fits can be installed around the edges of the data acquisition module. Those skilled in the art can vary the number of snap-fits (1, 2, 3, 4, etc.) according to actual needs. Slots that can cooperate with the snap-fits are then made on the horizontal channel 7 at the corresponding positions. The snap-fits on the data acquisition module are then directly embedded into the slots on the horizontal channel 7, thereby connecting the data acquisition module to the horizontal channel 7. When fixing by magnetic attraction, additional magnetic sheets can be set around the edge of the data acquisition module. Those skilled in the art can change the number of magnetic sheets according to the actual situation, such as 1, 2, 3, 4, etc. Then, opposite magnetic sheets that can attract the magnetic sheets are made on the horizontal channel 7 at the positions corresponding to the magnetic sheets. Then, the magnetic sheets on the data acquisition module are directly aligned with the opposite magnetic sheets embedded in the horizontal channel 7, thereby magnetically connecting the data acquisition module and the horizontal channel 7.

[0089] Of course, this embodiment is merely an example of fixed connection and detachable connection, but it does not limit the scope of the invention. Those skilled in the art can make changes according to the actual situation to achieve the same technical effect.

[0090] In an alternative embodiment, the seabed data center further includes a solar power panel 6 disposed on the sea surface, the solar power panel 6 being adapted to cover all horizontal channels 7.

[0091] With this setup, since the data center needs to draw power from the land-based power grid, a separate shore station needs to be built. The power supply cable needs to be submerged into the seabed, increasing the construction difficulty and the risk of leakage. Therefore, in addition to supplying power to the seabed data center and avoiding construction and leakage risks, the solar power panel 6 can also prevent sunlight from radiating heat to the outer wall of the cooling channel 2, thereby improving the heat dissipation of the cooling system 4 inside the seabed data center.

[0092] In one optional embodiment, the covering portion of the solar power generation panel 6 located above the maintenance channel 1 is separately configured. The covering portion has a folded state that exposes the maintenance channel 1 and a closed state that covers the maintenance channel 1 under the action of external force.

[0093] This design allows for easy access to the data terminal 3 from the maintenance access channel 1. The solar power generation panels 6 arranged on the sea surface are foldable and can be partially folded during maintenance, facilitating access to the maintenance access channel 1 without the need for back panel doors or other equipment. This design also saves a lot of space while generating electricity.

[0094] The driving force can be manual by a technician or automatically driven by a drive device. For manual operation, a handle can be installed on the cover, allowing the technician to open and close it directly. For automatic operation, it can be driven by a rotary motor or automatically opened and closed by an automatic hydraulic arm. Alternatively, the rotary motor and automatic hydraulic arm can be directly connected to a controller, allowing the technician to control the rotation of the cover by operating the controller. The rotary motor and automatic hydraulic arm can be operated by the controller. Of course, this embodiment is merely an example of the driving force for the cover and is not intended to limit it. Those skilled in the art can modify it according to actual conditions to achieve the same technical effect.

[0095] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
