Description

Technical Field

[0001] The present invention relates to the cross - technical field of offshore wind power and subsea data centers, and specifically to a collaborative system and optimization method for offshore wind power and subsea data centers. Background Art

[0002] With the development of ocean engineering technology, ocean exploration and development work has gradually moved from shallow seas to deep seas. Subsea data centers can provide space for various circuit and electrical components and are a popular direction for future subsea resource development. The key factors affecting the cost and function of subsea data centers are energy consumption and heat dissipation efficiency.

[0003] On the one hand, subsea data centers generally are powered by mains electricity. For example, in the data center systems disclosed in the prior arts CN114123477A and CN118748400A, the power supply module converts the electrical energy from the mains power grid into the target electrical energy received by the data warehouse of the data center, and uses a diesel generator as a backup power source to achieve uninterrupted power supply for the data center. Further, it can also combine energy storage devices to assist in temporary power supply, ultimately achieving the effect of reducing energy consumption. However, the cost of mains electricity is still relatively high, and generally, mains electricity does not entirely utilize clean energy, which leads to insufficient environmental friendliness. To address this problem, the prior art US20240089322A1 discloses an underwater data center system and energy storage, which uses an offshore wind power generation device for power supply, solving the technical problem of energy supply. However, the prior arts cannot solve how to ensure the continuous and stable heat dissipation of the heat dissipation unit under the power supply of clean energy such as offshore wind power to ensure the stable operation of the subsea data center.

[0004] On the other hand, a large amount of heat will inevitably be generated during the data storage process of subsea data centers. If the heat cannot be transmitted out in time, it will damage the precious circuit components of the data center. To solve the heat dissipation problem of subsea data centers, the most common approach at present is to seal the data center in a chamber and use a pump to circulate the water in the pipeline to achieve the purpose of cooling the equipment. For example, the subsea data center disclosed in the prior art CN117082830A uses a pump to form a cycle and perform heat exchange on the refrigerant at the heat dissipation end. However, the power supply of these heat dissipation units will also consume a considerable amount of energy. In addition, for the dual - loop cooling system for subsea data centers applicable to shallow sea areas disclosed in the prior art CN119603938A, it directly extracts seawater for heat dissipation through a pump and sets a filter to avoid pipeline blockage. However, the existing filters still have problems such as low filtering efficiency and affecting the heat dissipation effect, and the heat dissipation methods in the prior art are relatively single, with insufficient heat dissipation efficiency.

[0005] In summary, in the prior art, there is a lack of a marine data center system that collaboratively solves energy consumption and heat dissipation efficiency. Therefore, it is particularly important to invent a collaborative system for offshore wind power and subsea data centers and a heat dissipation optimization device, enabling it to utilize clean energy and achieve efficient heat dissipation underwater. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the present invention provides a collaborative system for offshore wind power and subsea data centers and an optimization method, comprehensively utilizing the heat dissipation energy structure of offshore wind power and diesel power generation to overcome the problems of the prior art. Through improvements in water cooling, heat dissipation fins, and heat conduction tubes, the system can significantly improve the heat dissipation efficiency, has a low manufacturing cost, and has good applicability, which can solve the problems of insufficient heat dissipation energy, lack of cleanliness, and low heat dissipation efficiency, greatly saving manpower and material resources.

[0007] To achieve the above object, the present invention provides the following technical solutions: A collaborative system for offshore wind power and subsea data centers includes a wind power generation unit, a diesel power generation unit, an energy storage unit, a subsea data center, and a heat dissipation unit.

The heat dissipation unit is arranged in the subsea data center and is connected to the data cabin. The power transmission device transmits the electric energy stored in the energy storage device to the heat dissipation unit, used to drive the heat dissipation unit to dissipate heat from the data cabin.

[0008] Further, the wind power generation unit includes a floating offshore wind turbine; and / or, the diesel power generation unit includes a diesel generator, and the diesel generator is arranged on a floating platform.

[0009] Further, the data cabin has a housing. The heat dissipation unit includes a water inlet pipe, a drain pipe, an infusion pump, a connecting pipe, a heat conduction tube, and heat dissipation fins. Among them, one side nozzle of the water inlet pipe is communicated with seawater, and the other side of the water inlet pipe is sequentially connected with the connecting pipe and the drain pipe. The infusion pump is arranged between the water inlet pipe and the connecting pipe. The connecting pipe is arranged in the housing, and a plurality of the heat dissipation fins are arranged on the outer wall of the connecting pipe. The plurality of heat dissipation fins are arranged in a circumferential array centered on the connecting pipe. A plurality of the heat conduction tubes are welded on the inner and outer walls of the housing. Each heat conduction tube passes through both side walls of the housing to keep communication, and a refrigerant is arranged inside the heat conduction tube.

[0010] Further, a plurality of the heat conduction tubes are arranged in a circumferential array centered on the connecting tube. The outer shell of the heat conduction tube is made of metallic copper, and the inner wall of the heat conduction tube is a sintered powdery tube core.

[0011] Further, the heat dissipation fins are made of metallic copper; and / or, the refrigerant is liquid ammonia as a liquid working medium; and / or, the surface of the housing is coated with a graphene heat dissipation film.

[0012] Further, a filtering mechanism is further included. The filtering mechanism is arranged on the side where the water inlet pipe is communicated with seawater. The filtering mechanism includes a front end cover, a filtering water tank, and a filtering conduit. One end of the filtering water tank is provided with a water inlet. The front end cover is arranged at the water inlet of the filtering water tank. The other end of the filtering water tank is provided with a water outlet, and the water outlet is communicated with the water inlet pipe. The front end cover is connected to one end of the filtering conduit, and the other end of the filtering conduit is a closed structure. The filtering conduit is arranged in the filtering water tank, and the filtering conduit is a tubular structure with fine annular gaps.

[0013] Further, both the front end cover and the filtering conduit are detachable structures.

[0014] Further, a bearing frame is further included, and the bearing frame is arranged between the filtering water tank and the water inlet pipe.

[0015] Further, the data cabin is arranged on the seabed near the land through a support structure. The support structure includes a support base placed on the seabed and support columns arranged on the support base, and the housing is installed on the support columns.

[0016] Further, the present invention also proposes an optimization method for a collaborative system of offshore wind power and undersea data centers, specifically including the following steps: S1: The wind power generation unit collects offshore wind power and transmits it to the energy storage device of the energy storage unit, and the energy storage unit converts the offshore wind power into stable electric energy; S2: According to the heat dissipation requirements of the data cabin, the power transmission device adjusts the output of the electric energy stored in the energy storage device and controls the power of the infusion pump in the heat dissipation unit, and the infusion pump controls the water flow rate of seawater flowing into the data cabin; S3: Under the action of the infusion pump, seawater is initially filtered through the front end cover of the filtering mechanism, then further filtered through the filtering conduit, and enters the filtering water tank; S4: The seawater in the filtering water tank enters the connecting pipe through the water inlet pipe, and the seawater exchanges heat with the heat generated in the data cabin through the heat dissipation fins; S5: The seawater after heat exchange is discharged from the heat dissipation unit through the drain pipe. In case of emergency, the diesel power generation unit is used to generate electricity and transmit the electric energy to the energy storage unit to ensure the stable supply of electric energy. The refrigerant in the heat conduction pipe inside the housing will always exchange heat with the heat inside the data cabin, and then the refrigerant flows to the heat conduction pipe outside the housing to exchange heat with seawater. After the refrigerant exchanges heat, it flows back into the heat conduction pipe inside the housing again for circulation.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) Through the wind power generation unit, the energy storage unit and the heat dissipation unit, the present invention converts offshore wind power into electric energy and maintains the power supply to the heat dissipation unit. On the one hand, the unstable offshore wind power can be converted into stable electric energy through the energy storage unit, realizing the stable supply of clean energy. On the other hand, the electric energy supplied to the energy storage unit by the wind power generation unit is directly used to supply the heat dissipation unit connected to the undersea data center, which can ensure the stable continuous heat dissipation of the heat dissipation unit. For emergencies, the diesel power generation unit is used as a backup power supply. In this way, the energy storage unit can always have the electric energy to ensure the stable operation of the heat dissipation unit, realizing a double insurance for the power supply of the heat dissipation unit, ensuring the stable operation of the heat dissipation unit, and further ensuring the stable and normal operation of the undersea data center.

[0018] (2) The present invention proposes the structural setting of the heat dissipation unit with multiple heat dissipation methods. First, through the setting of the infusion pump, the pumping of water can be controlled by electric energy, and the heat dissipation rate can be adjusted by controlling the water flow rate. Secondly, the cooling mechanism realizes the heat exchange between seawater and the data cabin inside the housing by setting a connecting pipe with heat dissipation fins inside the housing of the data cabin. Thirdly, the cooling mechanism also realizes the heat exchange between seawater outside the housing of the data cabin and the heat generated by the data cabin through the heat conduction pipe arranged outside the housing of the data cabin, that is, the present invention proposes an efficient heat dissipation structure for seawater to realize internal and external heat exchange in the data cabin at the same time. Moreover, not only the electric energy converted and supplied by offshore wind power realizes the energy supply to the infusion pump and the heat exchange of seawater, but also the evaporation cooling of the refrigerant in the heat conduction pipe can realize the heat dissipation method without electric energy supply. Therefore, even in case of emergency, the minimum heat dissipation requirement of the undersea data center can still be ensured.

[0019] (3) The present invention also proposes a filtering mechanism. First, the larger impurities in the seawater pumped by the infusion pump are initially filtered by the front end cover, and then the more fine impurities in the seawater are secondarily filtered through the tubular structure with fine annular gaps of the filter conduit arranged in the filter water tank, so that the seawater entering the filter water tank has fewer impurities and will not block the pump body and pipeline for heat dissipation. Further, the impurities accumulated in the filter conduit can be cleaned through the detachable setting. Description of the Drawings

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 - 6, the present invention provides a technical solution: a collaborative system for offshore wind power and undersea data center, including a wind power generation unit 17, a diesel power generation unit 18, an energy storage unit 20, an undersea data center and a heat dissipation unit 2. The undersea data center includes a data cabin 21. The wind power generation unit 17 is used to collect offshore wind power and transmit it to the energy storage unit 20. The diesel power generation unit 18 is used to generate electricity in case of emergency and transmit it to the energy storage unit 20. The energy storage unit 20 includes an energy storage device and a power transmission device. The energy storage device is used to store the electric energy converted by the wind power generation unit 17 and the diesel power generation unit 18. The heat dissipation unit 2 is arranged in the undersea data center. The heat dissipation unit 2 is connected to the data cabin 21. The power transmission device transmits the electric energy stored in the energy storage device to the heat dissipation unit 2, for driving the heat dissipation unit 2 to dissipate heat from the data cabin 21.

[0023] Through the wind power generation unit, the energy storage unit and the heat dissipation unit, the present invention converts offshore wind power into electric energy and maintains the power supply to the heat dissipation unit. On the one hand, through the energy storage unit, offshore wind power can be converted into stable electric energy, realizing the stable supply of clean energy. On the other hand, the electric energy supplied from the wind power generation unit to the energy storage unit is directly used to supply the heat dissipation unit connected to the undersea data center, which can ensure the stable continuous heat dissipation of the heat dissipation unit. For emergencies, the diesel power generation unit is used as a backup power supply. In this way, there is always electric energy in the energy storage unit that can ensure the stable operation of the heat dissipation unit, realizing a double insurance for the power supply of the heat dissipation unit, ensuring the stable operation of the heat dissipation unit, and further ensuring the stable and normal operation of the undersea data center.

[0024] Further, the wind power generation unit 17 includes a floating offshore wind turbine; the diesel power generation unit 18 includes a diesel generator, and the diesel generator is arranged on a floating platform 19.

[0025] In order to further improve the heat dissipation performance of the collaborative system for offshore wind power and undersea data center, the present invention also proposes a specific structural setting of a heat dissipation unit integrating various heat dissipation methods. Specifically, the data cabin 21 has a housing 1 ( Figures 3 - 4For the convenience of showing the structural arrangement of the heat dissipation unit, mainly the two side parts of the housing are shown, and the part of the housing above for surrounding the connecting pipe 10 is not shown in the figure). The heat dissipation unit 2 includes a water inlet pipe 7, a drain pipe 8, an infusion pump 9, a connecting pipe 10, a heat conduction pipe 11 and heat dissipation fins 12. Among them, one side pipe orifice of the water inlet pipe 7 is communicated with seawater, and the other side of the water inlet pipe 7 is sequentially connected with a connecting pipe 10 and a drain pipe 8. An infusion pump 9 is arranged between the water inlet pipe 7 and the connecting pipe 10. The connecting pipe 10 is arranged in the housing 1, and a plurality of the heat dissipation fins 12 are arranged on the outer wall of the connecting pipe 10. The plurality of heat dissipation fins 12 are arranged in a circumferential array with the connecting pipe 10 as the center, and the material of the heat dissipation fins 12 is selected as metal copper with good heat conduction performance and corrosion resistance. A plurality of the heat conduction pipes 11 are welded on the inner and outer walls of the housing 1. Each heat conduction pipe 11 passes through the two side walls of the housing 1 and remains connected. A refrigerant is arranged inside the heat conduction pipe 11, and the refrigerant is liquid ammonia as a liquid working medium. When the liquid ammonia as the liquid working medium in the heat conduction pipe 11 inside the housing 1 absorbs the heat inside the data cabin 21, it will evaporate into a gas, and then the gas will flow to the heat conduction pipe 11 outside the housing 1. At this time, the gas is cooled again by the seawater and becomes a liquid, and then flows back into the heat conduction pipe 11 inside the housing 1 again. In this way, the cycle is repeated to achieve rapid heat conduction and heat dissipation.

[0026] First, through the setting of the infusion pump, the pumping of water can be controlled by using electric energy, and the heat dissipation rate can be adjusted by controlling the water flow rate. Secondly, the cooling mechanism realizes the heat exchange between seawater and the data cabin inside the housing by arranging a connecting pipe with heat dissipation fins in the housing of the data cabin. Thirdly, the cooling mechanism also realizes the heat exchange between seawater and the heat generated by the data cabin outside the housing of the data cabin through the heat conduction pipe arranged outside the housing of the data cabin, that is, the present invention proposes an efficient heat dissipation structure for seawater to realize internal and external heat exchange in the data cabin at the same time. Moreover, not only the energy supply of the infusion pump is realized through the electric energy converted and supplied by the offshore wind power, and the heat exchange of seawater is realized, but also the heat dissipation method without electric energy supply can be realized through the evaporation cooling of the refrigerant in the heat conduction pipe. Therefore, even in an emergency, the minimum heat dissipation requirement of the undersea data center can still be guaranteed.

[0027] Furthermore, a plurality of the heat conduction pipes 11 are arranged in a circumferential array with the connecting pipe 10 as the center. The outer shell of the heat conduction pipe 11 is made of metal copper, and the inner wall of the heat conduction pipe 11 is a sintered powder-like pipe core, which has the ability of rapid heat conduction and can realize the efficient and rapid heat exchange between the heat of the data cabin 21 and the low-temperature seawater.

[0028] Furthermore, a graphene heat dissipation film 13 is coated on the surface of the housing 1, which can be further used to assist in accelerating heat dissipation, improving heat dissipation efficiency and saving energy.

[0029] In order to further ensure the heat dissipation performance of the offshore wind power and subsea data center collaborative system, the offshore wind power and subsea data center collaborative system further includes a filtering mechanism 3. The filtering mechanism 3 is arranged on the side where the water inlet pipe 7 is connected to seawater. The filtering mechanism 3 includes a front end cover 4, a filtering water tank 5 and a filtering conduit 6. One end of the filtering water tank 5 is provided with a water inlet, the front end cover 4 is arranged at the water inlet of the filtering water tank 5, the other end of the filtering water tank 5 is provided with a water outlet, and the water outlet is communicated with the water inlet pipe 7. When the front end cover 4 is used for the infusion pump 9 to suck seawater for heat dissipation, it initially filters larger impurities in the seawater. The front end cover 4 is connected to one end of the filtering conduit 6, and the other end of the filtering conduit 6 is a closed structure. The filtering conduit 6 is arranged in the filtering water tank 5. The filtering conduit 6 is a tubular structure with fine annular gaps. The seawater initially filtered by the front end cover 4 will enter the filtering conduit 6, and then through the fine annular gaps, the finer impurities in the seawater are filtered for the second time, and the impurities are accumulated in the filtering conduit 6, so that the seawater entering the filtering water tank 5 has fewer impurities and will not block the pump body and pipeline for heat dissipation.

[0030] Furthermore, both the front end cover 4 and the filtering conduit 6 are detachable structures. When too many impurities accumulate, they can be disassembled, repaired and replaced by a subsea robot or manual underwater operation.

[0031] Furthermore, it may further include a carrier frame 14. The carrier frame 14 is arranged between the filtering water tank 5 and the water inlet pipe 7, used to support the filtering water tank 5 and ensure the stable connection between the water inlet pipe 7 and the filtering water tank 5.

[0032] Furthermore, the data cabin 21 is arranged on the seabed 22 near the land 23 through a support structure. The support structure includes a support base 15 placed on the seabed 22 and support columns 16 arranged on the support base 15. The housing 1 is installed on the support columns 16.

[0033] In addition, the present invention also proposes an optimization method for the offshore wind power and subsea data center collaborative system, which specifically includes the following steps: S1: The wind power generation unit collects offshore wind power and transmits it to the energy storage device of the energy storage unit. The energy storage unit converts the offshore wind power into stable electric energy; S2: According to the heat dissipation requirements of the data cabin, the power transmission device adjusts the output of the electric energy stored in the energy storage device and controls the power of the infusion pump in the heat dissipation unit. The infusion pump controls the water flow rate of the seawater flowing into the data cabin; S3: Under the action of the infusion pump, the seawater is initially filtered through the front end cover of the filtering mechanism, then filtered for the second time through the filtering conduit, and enters the filtering water tank; S4: The seawater in the filtering water tank enters the connecting pipe through the water inlet pipe, and the seawater exchanges heat with the heat generated in the data cabin through the heat dissipation fins; S5: The seawater that has undergone heat exchange is discharged from the heat dissipation unit through the drain pipe; In case of emergency, the diesel power generation unit is used for power generation and transmits the electric energy to the energy storage unit to ensure stable power supply; The refrigerant in the heat conduction pipe inside the housing will always exchange heat with the heat inside the data cabin, and then the refrigerant flows to the heat conduction pipe outside the housing to exchange heat with seawater. After the refrigerant exchanges heat, it flows back into the heat conduction pipe inside the housing again for circulation, ensuring the heat dissipation requirements of the submarine cabin to the minimum extent.
