Description

Technical Field

[0001] The present invention relates to the technical field of comprehensive utilization of marine renewable energy, and in particular to an integrated power supply and cooling system for an offshore wind turbine server and a dynamic cooling method. Background Art

[0002] As coastal areas accelerate their energy transition, offshore renewable energy development has become a strategic priority. Offshore wind power, with its abundant resources and stable power generation, has become a core area of ​​development. However, the construction and operation of offshore wind farms currently face multiple systemic technical bottlenecks:

[0003] First, local energy consumption capacity is insufficient. Limited by the capacity of island power grids and technical bottlenecks in long-distance transmission, large-scale offshore wind power generation is difficult to efficiently utilize locally, forcing a significant amount of clean energy to be abandoned. In extreme weather conditions such as typhoons, periodic shutdowns are required to ensure grid security, further exacerbating energy waste and limiting the utilization of wind energy resources.

[0004] Second, the data management architecture is flawed. Traditional offshore wind farms rely on land-based servers for remote data collection and processing, resulting in high data transmission latency and poor reliability. This fails to meet the technical requirements of smart wind farms for real-time monitoring, fault warnings, and dynamic scheduling. Furthermore, the spatial separation of power generation units and data processing units increases the cost of laying submarine optical cables and makes data loss more likely due to transmission link failures.

[0005] Third, the equipment has poor adaptability to the operating environment. The harsh offshore environment of high humidity and high salt spray poses a severe challenge to the durability of electronic equipment. This is especially true for core equipment like servers, where the heat dissipation requirements and corrosion protection requirements are in stark conflict. Traditional compressor cooling solutions consume a lot of energy, which conflicts with the limited power supply capacity of offshore platforms. Natural convection cooling is inefficient, making it difficult to maintain stable equipment operation in high-temperature and high-humidity environments. This leads to frequent server failures due to overheating or corrosion, increasing maintenance costs and the risk of downtime.

[0006] Fourth, the system integration is low. In existing offshore energy systems, wind power generation facilities, data servers, energy storage equipment, and cooling systems are mostly distributed in a discrete layout, lacking organic integration. This not only occupies a large amount of offshore space, but also leads to poor equipment coordination and exponentially increased maintenance complexity, seriously restricting the intelligent and efficient operation of offshore wind farms.

[0007] Therefore, in order to address the problems of inefficient energy consumption, lagging data management, insufficient equipment environmental adaptability and low system integration in existing technologies, an innovative integrated solution is urgently needed to achieve stable power supply, efficient heat dissipation and efficient data management for offshore wind turbine servers, and improve the comprehensive utilization efficiency of marine renewable energy. Summary of the Invention

[0008] In view of this, the present invention provides an integrated power supply and cooling system for an offshore wind turbine server and a dynamic cooling method to solve the problems of inefficient energy consumption, lagging data management, insufficient equipment environmental adaptability and low system integration in the prior art.

[0009] In a first aspect, the present invention provides an integrated power supply and cooling system for an offshore wind turbine server, comprising:

[0010] A wind turbine tower, wherein a tower cabin with an enlarged inner diameter is provided at the bottom of the wind turbine tower;

[0011] A server assembly is arranged in the tower cabin, and the server assembly includes a server and a comprehensive energy storage device;

[0012] Dynamic response cooling device, including seawater circulation system and temperature monitoring unit;

[0013] The integrated energy storage device is connected to the wind turbine power supply system to store the surplus power generated by the wind turbine and to supply power to the server;

[0014] The seawater circulation system cools the server components by injecting or discharging seawater into the tower chamber.

[0015] The integrated tower nacelle design spatially aggregates power generation, storage, and consumption equipment, avoiding the space waste of traditional discrete layouts. It also reduces inter-device connectivity and facilitates maintenance. The integrated energy storage device's power buffering function addresses server power outages caused by unstable offshore wind power output, ensuring weather-independent data collection and processing, and enhancing the reliability of intelligent wind farm management. The dynamic response cooling system fully utilizes marine seawater resources. Compared to traditional compressor-based cooling solutions, it eliminates the need for significant additional power consumption, significantly reducing cooling system energy consumption and meeting the energy conservation needs of offshore platforms. Its closed-loop process of "temperature monitoring-seawater injection-heat exchange-seawater discharge" dynamically adjusts cooling intensity based on the server's real-time temperature, maintaining stable server operating temperatures in high-temperature and high-humidity marine environments. Its waterproof design also mitigates the risk of seawater corrosion, extending equipment life. The three elements work synergistically to create an integrated system of "energy generation-local consumption-equipment protection," enhancing the overall utilization efficiency of offshore wind energy while providing comprehensive assurance for stable server operation in harsh marine environments.

[0016] In an optional embodiment, the temperature monitoring unit includes:

[0017] A server temperature sensor is provided on one side of the server component to monitor the temperature of the server and the integrated energy storage device;

[0018] The seawater temperature monitor is arranged outside the wind turbine tower to monitor the external seawater temperature.

[0019] This dual-dimensional monitoring design not only enables direct status perception of the cooling object (server components), but also takes into account the environmental characteristics of the cooling medium (seawater), making the operation of the dynamic response cooling device more targeted and energy-efficient. While ensuring the temperature stability of the equipment, it minimizes the energy consumption of the cooling system and further improves the coordinated efficiency of the entire integrated power supply and cooling system.

[0020] In an optional embodiment, the seawater circulation system includes a water pump system and a drain outlet, the water pump system is arranged in the tower empty compartment, and the drain outlet is arranged at the bottom of the tower empty compartment;

[0021] When the server temperature sensor detects an abnormal temperature and the seawater temperature monitor detects a temperature lower than the server temperature, the water pump system is started to inject seawater;

[0022] When the server temperature returns to a safe threshold, the water pump system is started to discharge seawater.

[0023] The coordinated action of the water pump system and drain outlet enables automated closed-loop control of the cooling process, responding to equipment temperature changes without manual intervention. The startup logic based on temperature differential conditions (starting only when the seawater temperature is lower than the server temperature) avoids ineffective cooling energy consumption. For example, in the summer, when the seawater temperature approaches or exceeds the equipment safety threshold, the system automatically suspends seawater circulation to prevent cooling failure caused by insufficient heat exchange efficiency. The drain outlet is located at the bottom of the empty tank, utilizing gravity to assist drainage, shortening drainage time, reducing the period of seawater retention in the tank, and reducing the risk of salt spray corrosion.

[0024] Furthermore, the bidirectional operation of the water pump system (capable of both water intake and drainage) simplifies the piping structure, eliminating the need for an additional drainage pump and saving space within the empty tank. This precise, energy-efficient cooling cycle mechanism enables the servers to maintain optimal operating temperatures in the high temperature and humidity of the ocean, while minimizing cooling system energy consumption. This, in conjunction with the integrated energy storage device, further improves the overall system's energy efficiency.

[0025] In an optional embodiment, the server component is entirely encapsulated by a waterproof and heat-conductive material, and a seawater corrosion-resistant coating is sprayed on the surface.

[0026] This design enables server components to directly utilize seawater for efficient cooling while also being able to withstand the long-term erosion of the ocean's high-salt and high-humidity environment. This provides a core guarantee for the stable operation of the equipment, while reducing subsequent maintenance costs and improving the reliability and economy of the entire system.

[0027] In an optional embodiment, the integrated energy storage device has a built-in metal heat-conducting structure to absorb heat generated when the server is running and temporarily store the heat energy.

[0028] Metal thermal conductive structures (such as copper heat sink fins or aluminum thermal conductive brackets) are embedded in the integrated energy storage device and are tightly connected to the core heat-generating components of the server (such as the CPU and power module) through a heat conduction path. When the server generates heat during operation, the metal thermal conductive structure quickly absorbs the heat through direct contact. On the one hand, it transfers part of the heat to the external waterproof thermal conductive packaging layer to participate in the heat exchange with seawater; on the other hand, it uses the high thermal capacity characteristics of the metal material to temporarily store excess heat energy to form a "heat buffer pool." During low-load operation of the server or during the startup of the cooling system, the temporarily stored heat energy can be slowly released into the environment to avoid local high temperatures caused by instantaneous heat accumulation.

[0029] In an optional embodiment, the seawater circulation system is linked to the wind turbine blade signal, and seawater is injected as ballast when the wind speed exceeds a threshold.

[0030] This linkage design enables the seawater circulation system to have dynamic ballast adjustment capabilities in addition to its cooling function: the injected seawater can significantly lower the overall center of gravity of the wind turbine, enhancing its anti-overturning ability in strong wind environments. At the same time, there is no need to set up an additional independent ballast device, and the existing seawater circulation system can be used to achieve functional reuse, saving space in the tower compartment and equipment costs.

[0031] In an optional embodiment, a mesh support grid is provided in the tower cabin, and the mesh support grid divides the interior of the tower cabin into an upper cavity and a lower cavity;

[0032] The server assembly is located in the upper cavity and supported by the mesh support grid, and the seawater circulation system is located in the lower cavity.

[0033] The zoning design of the mesh support grid optimizes internal space utilization, prevents interference between server components and circulation system parts, and reduces the risk of equipment collisions. The grid's hollow structure ensures the free flow of seawater between the upper and lower cavities. In the event of an accidental leak in a server component, the grid quickly drains the leaked water to the lower cavity, minimizing the time it immerses electronic components.

[0034] In an optional embodiment, the tower nacelle is configured to lower the overall center of gravity of the wind turbine through an expanded diameter design, and its structure is suitable for a floating foundation or a fixed foundation.

[0035] This structural design not only breaks through the limitations of the traditional tower's "constant diameter or gradually decreasing diameter", achieves improved stability through morphological optimization, but also makes the system flexibly applicable to diverse offshore scenarios such as nearshore and offshore by being compatible with different foundation forms, providing structural support for the safe operation and functional integration of wind turbines in complex marine environments.

[0036] In an optional embodiment, the fixed foundation includes:

[0037] Transitional section foundation;

[0038] Pile foundation, the transition section foundation is connected between the tower cavity and the pile foundation, and the transition section foundation includes a hydraulic water storage cavity and a mechanical climbing device.

[0039] In a second aspect, the present invention further provides a dynamic cooling method for an offshore wind turbine server, which uses the integrated power supply and cooling system for an offshore wind turbine server, comprising the following steps:

[0040] Real-time acquisition of server component temperature and seawater temperature data;

[0041] When the server temperature exceeds a first threshold and the seawater temperature is lower than the server temperature, injecting seawater into the tower chamber;

[0042] When the server temperature drops to a second threshold, the seawater in the tower chamber is discharged.

[0043] This method achieves precision and energy saving in the cooling process through the closed-loop logic of "real-time monitoring-condition triggering-dynamic start and stop": based on the control strategy of dual temperature thresholds (the first threshold triggers cooling and the second threshold terminates cooling), it avoids equipment overheating caused by insufficient cooling or energy waste caused by excessive cooling; the starting condition that the seawater temperature is lower than the server temperature ensures that each cooling cycle can utilize the effective temperature difference to achieve efficient heat dissipation.

[0065] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0066] As coastal areas accelerate their energy transition, offshore renewable energy development has become a strategic priority. Offshore wind power, with its abundant resources and stable power generation, has become a core area of ​​development. However, the construction and operation of offshore wind farms currently face multiple systemic technical bottlenecks:

[0067] First, local energy consumption capacity is insufficient. Limited by the capacity of island power grids and technical bottlenecks in long-distance transmission, large-scale offshore wind power generation is difficult to efficiently utilize locally, forcing a significant amount of clean energy to be abandoned. In extreme weather conditions such as typhoons, periodic shutdowns are required to ensure grid security, further exacerbating energy waste and limiting the utilization of wind energy resources.

[0068] Second, the data management architecture is flawed. Traditional offshore wind farms rely on land-based servers for remote data collection and processing, resulting in high data transmission latency and poor reliability. This fails to meet the technical requirements of smart wind farms for real-time monitoring, fault warnings, and dynamic scheduling. Furthermore, the spatial separation of power generation units and data processing units increases the cost of laying submarine optical cables and makes data loss more likely due to transmission link failures.

[0069] Third, the equipment has poor adaptability to the operating environment. The harsh offshore environment of high humidity and high salt spray poses a severe challenge to the durability of electronic equipment. This is especially true for core equipment like servers, where the heat dissipation requirements and corrosion protection requirements are in stark conflict. Traditional compressor cooling solutions consume a lot of energy, which conflicts with the limited power supply capacity of offshore platforms. Natural convection cooling is inefficient, making it difficult to maintain stable equipment operation in high-temperature and high-humidity environments. This leads to frequent server failures due to overheating or corrosion, increasing maintenance costs and the risk of downtime.

[0070] Fourth, the system integration is low. In existing offshore energy systems, wind power generation facilities, data servers, energy storage equipment, and cooling systems are mostly distributed in a discrete layout, lacking organic integration. This not only occupies a large amount of offshore space, but also leads to poor equipment coordination and exponentially increased maintenance complexity, seriously restricting the intelligent and efficient operation of offshore wind farms.

[0071] Therefore, in order to address the problems of inefficient energy consumption, lagging data management, insufficient equipment environmental adaptability and low system integration in existing technologies, an innovative integrated solution is urgently needed to achieve stable power supply, efficient heat dissipation and efficient data management for offshore wind turbine servers, and improve the comprehensive utilization efficiency of marine renewable energy.

[0072] In view of this, the present invention provides an integrated power supply and cooling system for an offshore wind turbine server to solve the problems of inefficient energy consumption, lagging data management, insufficient equipment environment adaptability and low system integration in the prior art.

[0073] The following combination Figures 1 to 4 , describing embodiments of the present invention.

[0074] According to an embodiment of the present invention, on the one hand, an integrated power supply and cooling system for offshore wind turbine servers is provided, comprising a wind turbine tower 2, a server assembly, and a dynamic response cooling device. A tower cabin 3 with an enlarged inner diameter is provided at the bottom of the wind turbine tower 2; the server assembly is arranged in the tower cabin 3, and the server assembly includes a server 5 and an integrated energy storage device 6; the dynamic response cooling device includes a seawater circulation system and a temperature monitoring unit; wherein the integrated energy storage device 6 is connected to the wind turbine power supply system, and is used to store the surplus power generated by the wind turbine and supply power to the server 5; the seawater circulation system cools the server assembly by injecting or discharging seawater into the tower cabin 3.

[0075] The integrated power supply and cooling system for offshore wind turbine servers achieves on-site consumption of offshore wind power resources, stable power supply and efficient heat dissipation for the server 5 through the coordinated design of the wind turbine tower 2, server components and dynamic response cooling devices.

[0076] Specifically, the enlarged inner diameter of the wind turbine tower 2, creating a hollow tower chamber 3, provides integrated installation space for the server components. This not only utilizes the unused space in the tower structure, but also reduces the overall center of gravity of the wind turbine through the enlarged inner diameter design, improving the stability of the equipment in offshore environments. The integrated energy storage device 6 in the server component is directly connected to the wind turbine power supply system. When the wind turbine is generating electricity normally, it can store surplus energy. When extreme weather conditions such as calm or strong winds cause the wind turbine to shut down or generate insufficient power, the integrated energy storage device 6 can immediately power the server 5, ensuring its continued operation and the continuity of data recording.

[0077] The temperature monitoring unit of the dynamic response cooling device collects the operating temperature of the server 5 in real time. When the server 5 temperature exceeds a preset threshold, the seawater circulation system activates: a water pump injects seawater into the tower's empty compartment 3, removing heat through heat exchange between the seawater and the server components. Once the temperature monitoring unit detects that the server 5 temperature has dropped to a safe range, the seawater circulation system discharges the seawater from the empty compartment, completing the cooling cycle. During this process, the server components are encased in a waterproof, thermally conductive material, ensuring efficient heat transfer to the seawater while also protecting the electronic equipment from seawater corrosion.

[0078] The integrated design of the tower nacelle 3 spatially aggregates the "power generation-storage-energy consumption" equipment, avoiding the space waste of traditional discrete layouts. It also reduces the complexity of inter-device connections, facilitating future maintenance. The integrated energy storage device 6 provides power buffering, resolving power outages in servers 5 caused by unstable offshore wind power output. This allows data collection and processing to be unaffected by weather, enhancing the reliability of intelligent wind farm management.

[0079] The dynamic response cooling device fully utilizes the seawater resources in the marine environment. Compared with traditional compressor refrigeration solutions, it does not require additional large amounts of electricity consumption, significantly reducing the energy consumption of the cooling system and meeting the energy-saving needs of offshore platforms. Its closed-loop process of "temperature monitoring-seawater injection-heat exchange-seawater discharge" can dynamically adjust the cooling intensity according to the real-time temperature of Server 5, maintaining a stable operating temperature of Server 5 in the high temperature and high humidity marine environment. At the same time, the waterproof design avoids the risk of seawater corrosion and extends the service life of the equipment. The three work together to build an integrated system of "energy production-on-site consumption-equipment protection", which not only improves the comprehensive utilization efficiency of offshore wind energy, but also provides all-round protection for the stable operation of Server 5 in the harsh marine environment.

[0080] In one embodiment, the temperature monitoring unit includes a server temperature sensor 7, located on one side of the server assembly, to monitor the temperature of the server 5 and the integrated energy storage device 6; and a seawater temperature monitor 11, located outside the wind turbine tower 2, to monitor the external seawater temperature. The combination of the server temperature sensor 7 and the seawater temperature monitor 11 in the temperature monitoring unit establishes a multi-dimensional temperature sensing system, providing data support for the precise regulation of the dynamic response cooling device. Its working method and effects are as follows:

[0081] The server temperature sensor 7 is installed on one side of the server component. It collects the operating temperature of the server 5 motherboard, chip and integrated energy storage device 6 battery pack in real time through direct contact or near-field sensing, forming a temperature data chain of the core heating components of the equipment. The seawater temperature monitor 11 is fixed in the underwater area outside the wind turbine tower 2, continuously monitoring the real-time temperature of the external seawater and establishing a reference value for the ocean environment temperature. The temperature data collected by both are synchronously transmitted to the control unit of the cooling system. The control unit dynamically determines whether to start the cooling cycle and determine the amount of seawater injection by comparing the real-time temperature of the server component with the preset safety threshold (such as 85°C for the server chip and 55°C for the energy storage battery), combined with the temperature difference between the seawater temperature and the equipment temperature.

[0082] Close-range monitoring by the server temperature sensor 7 ensures accurate detection of equipment heating conditions, enabling timely detection of localized overheating risks (such as transient chip overheating) and preventing equipment damage caused by the lag in overall cabin temperature monitoring. The ambient temperature parameters provided by the seawater temperature monitor 11 enable the control unit to dynamically optimize the cooling strategy based on the temperature difference. When the seawater temperature is below the equipment temperature threshold and the temperature difference is large (e.g., ≥15°C), the seawater injection rate can be reduced to reduce cycle energy consumption. When the seawater temperature is high (e.g., approaching the equipment safety threshold), the injection rate is increased and the cycle interval is shortened to ensure efficient cooling.

[0083] This dual-dimensional monitoring design not only enables direct status perception of the cooling object (server components), but also takes into account the environmental characteristics of the cooling medium (seawater), making the operation of the dynamic response cooling device more targeted and energy-efficient. While ensuring the temperature stability of the equipment, it minimizes the energy consumption of the cooling system and further improves the coordinated efficiency of the entire integrated power supply and cooling system.

[0084] Furthermore, the seawater circulation system includes a water pump system 10 and a drain outlet 9. The water pump system 10 is arranged in the tower compartment 3, and the drain outlet 9 is arranged at the bottom of the tower compartment 3. When the server temperature sensor 7 detects an abnormal temperature and the seawater temperature monitor 11 detects a temperature lower than the temperature of the server 5, the water pump system 10 is started to inject seawater; when the temperature of the server 5 returns to the safety threshold, the water pump system 10 is started to discharge the seawater.

[0085] The coordinated design of the water pump system 10 and drain outlet 9 in the seawater circulation system incorporates precise cooling control logic based on temperature differential response. The water pump system 10 is integrated within the tower hollow chamber 3 and connected to the external seawater environment via piping. The drain outlet 9 is located at the bottom of the hollow chamber and equipped with a control valve. When the server temperature sensor 7 detects that the device temperature exceeds a safety threshold (e.g., 85°C for the server and 55°C for the energy storage device), and the seawater temperature monitor 11 indicates that the external seawater temperature is lower than the actual temperature of the server 5 (creating an effective heat dissipation temperature difference), the control system triggers the water pump system 10 to start, pumping low-temperature seawater into the tower hollow chamber 3 until the seawater submerges the heat-conducting housing of the server components but avoids contact with the electronic components. At this point, the seawater absorbs heat from the equipment through heat conduction, gradually lowering the temperature of the server 5. When the server temperature sensor 7 detects that the device temperature drops below the safety threshold (e.g., 60°C for the server and 40°C for the energy storage device), the control system closes the water inlet valve and opens the control valve at drain outlet 9. Simultaneously, the reverse drainage function of the water pump system 10 is activated to quickly discharge the absorbed heat seawater out of the hollow chamber, completing a cooling cycle.

[0086] The coordinated action of the water pump system 10 and the drain outlet 9 enables automated closed-loop control of the cooling process, responding to changes in device temperature without manual intervention. The temperature-differential activation logic (activating only when the seawater temperature is lower than that of the server 5) avoids ineffective cooling energy consumption. For example, in the summer, when the seawater temperature approaches or exceeds the device's safety threshold, the system automatically suspends seawater circulation to prevent cooling failure caused by insufficient heat exchange efficiency. The drain outlet 9, located at the bottom of the empty tank, utilizes gravity to assist drainage, shortening drainage time, reducing the period of seawater retention in the tank, and reducing the risk of salt spray corrosion.

[0087] Furthermore, the bidirectional operation of the water pump system 10 (capable of both water intake and drainage) simplifies the piping structure, eliminating the need for an additional drainage pump and saving space within the empty cabin. This precise, energy-efficient cooling cycle mechanism enables the server 5 to maintain an optimal operating temperature in the high-temperature and high-humidity environment at sea, while minimizing cooling system energy consumption. This, in conjunction with the integrated energy storage device 6, further improves the overall system's energy efficiency.

[0088] In one embodiment, the entire server component is encapsulated by a waterproof and heat-conductive material, and a seawater corrosion-resistant coating is sprayed on the surface.

[0089] The server components are encapsulated with waterproof thermal conductive materials and sprayed with a seawater corrosion-resistant coating, which not only ensures heat dissipation efficiency but also builds a reliable anti-corrosion barrier. The waterproof thermal conductive material (such as a silicone rubber composite material with added graphene) is used to wrap the server 5 and the integrated energy storage device 6 as a whole to form a closed packaging structure: on the one hand, the high thermal conductivity of the material can quickly transfer the heat generated by the operation of the server 5 to the outer surface, providing an efficient path for heat exchange with seawater; on the other hand, its dense molecular structure can block seawater penetration and prevent electronic components from coming into direct contact with seawater. The seawater corrosion-resistant coating (such as a polytetrafluoroethylene-based anti-corrosion coating) sprayed on the surface forms a secondary protection, resisting the erosion of seawater salt spray through its inert chemical properties and slowing down the aging of the packaging material. When seawater is injected into the seawater circulation system, the encapsulated server components can directly contact the seawater, and heat is efficiently transferred through the path of "server chip → waterproof thermal conductive packaging layer → seawater". At the same time, the double protection structure ensures that seawater cannot invade the interior of the equipment.

[0090] This design enables server components to directly utilize seawater for efficient cooling while also being able to withstand the long-term erosion of the ocean's high-salt and high-humidity environment. This provides a core guarantee for the stable operation of the equipment, while reducing subsequent maintenance costs and improving the reliability and economy of the entire system.

[0091] In one embodiment, the integrated energy storage device 6 has a built-in metal heat-conducting structure to absorb the heat generated by the server 5 during operation and temporarily store the heat energy.

[0092] The metal heat-conducting structure (such as copper heat sink fins or aluminum heat-conducting brackets) is embedded in the integrated energy storage device 6 and is tightly connected to the core heat-generating components of the server 5 (such as the CPU and power module) through a heat conduction path. When the server 5 generates heat during operation, the metal heat-conducting structure quickly absorbs the heat through direct contact. On the one hand, it transfers part of the heat to the external waterproof heat-conducting packaging layer to participate in the heat exchange of seawater; on the other hand, it uses the high heat capacity characteristics of the metal material to temporarily store excess heat energy to form a "heat buffer pool." During the low-load operation of the server 5 or the startup of the cooling system, the temporarily stored heat energy can be slowly released into the environment to avoid local high temperatures caused by instantaneous heat accumulation.

[0093] In one embodiment, the seawater circulation system is linked to the signal of the wind turbine blade 1, and seawater is injected as ballast when the wind speed exceeds a threshold.

[0094] The seawater circulation system establishes a signal connection with the wind speed monitoring module of the wind turbine blades 1 via sensors, receiving real-time wind speed data. When the wind speed exceeds a preset safety threshold, the control system triggers the seawater circulation system's pump system 10 to inject a large amount of seawater into the tower's plenum 3, using the seawater's weight to increase the tower's bottom ballast. Once the wind speed drops to a safe range, the pump system 10 then drains the seawater, restoring the turbine's original counterweight.

[0095] This linkage design enables the seawater circulation system to have dynamic ballast adjustment capabilities in addition to its cooling function: the injected seawater can significantly lower the overall center of gravity of the wind turbine, enhancing its anti-overturning ability in strong wind environments. At the same time, there is no need to set up an additional independent ballast device, and the existing seawater circulation system can be used to achieve functional reuse, saving space and equipment costs in the tower compartment 3.

[0096] In one embodiment, a mesh support grid 8 is provided in the tower cabin 3, which divides the interior of the tower cabin 3 into an upper cavity and a lower cavity; the server components are located in the upper cavity and supported by the mesh support grid 8, and the seawater circulation system is located in the lower cavity.

[0097] A mesh support grid 8 is horizontally installed within the tower compartment 3, dividing the compartment into two independent cavities, upper and lower. The server components are placed in the upper cavity, where they are stably supported by the grid structure, with their weight evenly distributed across the grid frame. The core components of the seawater circulation system, such as the pumps and piping, are installed in the lower cavity, physically separating them from the upper server components. When the seawater circulation system is activated, seawater is first injected into the lower cavity. As the water level rises, it flows over the grid into the upper cavity, where it contacts the waterproof and thermally conductive encapsulation layer of the server components, completing the heat exchange. During drainage, the seawater is quickly discharged from the drain port 9 in the lower cavity. The grid structure of the grid does not impede the flow of water, ensuring smooth circulation.

[0098] Effectively, the zoning design of the mesh support grid 8 optimizes internal space utilization, prevents interference between server components and circulatory system components, and reduces the risk of equipment collisions. The grid's hollow structure ensures the free flow of seawater between the upper and lower cavities. In the event of an accidental leak in a server component, the grid quickly drains the leaked water to the lower cavity, minimizing the time it immerses electronic components.

[0099] In one embodiment, the tower nacelle 3 is configured to lower the overall center of gravity of the wind turbine through an expanded diameter design, and its structure is adapted to a floating foundation 4 or a fixed foundation.

[0100] By expanding the bottom inner diameter of the tower nacelle 3, the nacelle has an overall "wide at the bottom, narrow at the top" structure. This, combined with the weight distribution of the internal server components and integrated energy storage device 6, shifts the turbine's center of gravity downward to the tower's base, lowering the overall center of gravity. For floating wind turbines, the expanded tower nacelle 3 is rigidly connected to a floating foundation 4 (such as a semi-submersible or column-type float). The weight of the nacelle balances the buoyancy of the float, enhancing the turbine's stability in waves. For fixed wind turbines, the expanded nacelle is secured to the pile foundation, increasing the bottom load-bearing area and more evenly transferring the upper load to the seabed, improving its anti-overturning capability.

[0101] This structural design not only breaks through the limitations of the traditional tower's "constant diameter or gradually decreasing diameter", achieves improved stability through morphological optimization, but also makes the system flexibly applicable to diverse offshore scenarios such as nearshore and offshore by being compatible with different foundation forms, providing structural support for the safe operation and functional integration of wind turbines in complex marine environments.

[0102] In one embodiment, the fixed foundation includes a transition section foundation 12 and a pile foundation 13 . The transition section foundation 12 is connected between the tower cavity 3 and the pile foundation 13 . The transition section foundation 12 includes a hydraulic water storage cavity 14 and a mechanical climbing device 15 .

[0103] The pile foundation 13 is fixed to the seabed, providing a solid support for the entire wind turbine. The transition section foundation 12 is connected between the tower chamber 3 and the pile foundation 13, serving as a connecting hub between the two. The hydraulic water storage chamber 14 is built into the transition section foundation 12, and can be injected and discharged with an external water pump. Figure 4 As shown, a hydraulic water storage tank 14 is mounted outside the upper end of the pile foundation 13. A mechanical climbing device 15, driven by hydraulics or a gear transmission mechanism, enables the tower tank 3 to be raised and lowered relative to the pile foundation 13. The hydraulic water storage tank 14 draws in and out seawater to assist the wind turbine in rising and sinking, while also providing seawater for cooling the tower tank 3, which houses the waterproofed servers 5 above. The transitional foundation 12 overcomes the rigid connection limitations of the tower tank 3 and pile foundation 13 in fixed wind turbines, enabling the tank to be raised and lowered.

[0104] According to another aspect of an embodiment of the present invention, a dynamic cooling method for an offshore wind turbine server is provided, which uses an integrated power supply and cooling system for an offshore wind turbine server and includes the following steps:

[0105] Real-time acquisition of server component temperature and seawater temperature data;

[0106] When the temperature of the server 5 exceeds the first threshold and the seawater temperature is lower than the temperature of the server 5, injecting seawater into the tower chamber 3;

[0107] When the temperature of the server 5 drops to a second threshold, the seawater in the tower chamber 3 is discharged.

[0108] The dynamic cooling method for the offshore wind turbine server is based on the integrated power supply and cooling system of the offshore wind turbine server, and achieves precise temperature control of the server 5 through real-time monitoring and dynamic regulation.

[0109] From a workflow perspective, the method begins with temperature monitoring: server temperature sensors 7 collect the operating temperatures of server 5 and integrated energy storage device 6 (e.g., chip temperature, battery pack temperature) in real time, while seawater temperature monitor 11 simultaneously acquires the external seawater temperature. Both types of data are continuously transmitted to the control system. When the control system determines that the server 5 temperature exceeds a first threshold (e.g., 80°C for server core components and 650°C for integrated energy storage devices), and the seawater temperature is lower than the current server 5 temperature (ensuring an effective heat dissipation temperature difference), the seawater circulation system is immediately triggered: the water pump system 10 is activated to inject seawater into the tower chamber 3. The seawater enters the upper cavity through the mesh support grid 8, comes into contact with the waterproof and thermally conductive material encapsulating the server components, and absorbs heat through heat exchange. When the server temperature sensor 7 detects that the temperature has dropped to a second threshold (e.g., 60°C for server core components and 40°C for integrated energy storage devices), the control system initiates the drainage process. The water pump system 10 operates in reverse, cooperating with the bottom drain port 9 to discharge the absorbed heat seawater out of the tower chamber 3, completing a cooling cycle.

[0110] This method achieves precision and energy saving in the cooling process through the closed-loop logic of "real-time monitoring-condition triggering-dynamic start and stop": based on the control strategy of dual temperature thresholds (the first threshold triggers cooling and the second threshold terminates cooling), it avoids equipment overheating caused by insufficient cooling or energy waste caused by excessive cooling; the starting condition that the seawater temperature is lower than the temperature of server 5 ensures that each cooling cycle can utilize the effective temperature difference to achieve efficient heat dissipation.

[0111] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention. Such modifications and variations are all within the scope defined by the appended claims.
