Description

Technical Field

[0001] The present invention belongs to the technical field of wind power and data centers, and relates to the technical field of integration of wind power and data centers, and specifically relates to a wind power tower-type data center and its power supply method, heat dissipation method, and heat dissipation device. Background Art

[0002] Cooling power consumption is the key factor affecting the PUE value of a data center.

[0003] In the information age, data is essential for everyday work and life. Internet data centers scattered across cities consume vast amounts of electricity and energy annually. By encouraging the development of high-end green data centers and gradually shutting down and converting smaller, outdated data centers, we can promote green data center development.

[0004] A recent research report states that with the rapid development of artificial intelligence, the demand for computing power has also led to a significant increase in electricity demand. As data centers continue to expand, the power grid must also expand, energy sources must be diversified, and infrastructure must be expanded to support the growing grid.

[0005] Data centers, as the primary computing infrastructure, face an increasingly significant conflict between their massive electricity demands and the inefficient and redundant traditional energy and power supply systems. The computing infrastructure industry is reaching a consensus on promoting "green DC" power consumption in data centers, transforming them from mere energy consumers into vital, flexible resources in new energy systems.

[0006] A large number of data center assets are facing idleness, and the energy supply system urgently needs to be restructured. Data centers need "green DC". The existing power supply model of data centers is facing problems such as stricter energy consumption indicators, continuously increasing electricity costs, high investment and low utilization rate of power facilities, and it is increasingly difficult for power expansion to match the rapid growth of computing power.

[0007] By building a green DC data center, creating an integrated source, grid, load and storage system, and providing various auxiliary services to the power grid through virtual power plants when necessary, we can promote the consumption of distributed new energy and meet the high-power electricity needs of super charging piles, ultimately achieving low-carbon, economical and efficient development, and becoming an important resource for the new power system.

[0008] There are three modes of “DCization” of data centers;

[0009] First, within existing data center campuses within cities, DC energy routers are used to connect buildings within the campus, which previously had separate power supply systems. This allows for resource sharing between buildings within the campus, also known as DC interconnection, thereby improving power allocation efficiency.

[0010] Second, build large-scale renewable energy power generation bases in base-type data centers around cities, creating an integrated power source, grid, load, and storage system. Using flexible direct current transmission technology, data centers can generate their own electricity for their own use, with surplus power fed back to the grid.

[0011] Third, use interconnected DC power grids to flexibly connect data centers with massive regulating resources within the city, such as distributed photovoltaics, energy storage, new energy vehicles, and charging pile and battery swap stations, to create a 100% green electricity-driven DC data center and use it as an important flexible regulating resource for the new energy system.

[0012] The first mode is medium-voltage direct current, which solves the problems of flexible interconnection, resource sharing, and safety and reliability of data centers in the power distribution link; the second mode is high-voltage direct current, which solves the green and low-carbon problems of data centers through green power supply and optimized transmission methods; the third mode can fully mobilize the enthusiasm of data centers and other surrounding users to spontaneously consume new energy, thereby improving the flexibility and safety of new power systems with a high proportion of renewable energy.

[0013] For high-energy-consuming data centers, lower temperatures are not always better. Cooling system energy consumption accounts for more than 1 / 3 of the total energy consumption of data centers, and many studies have talked about reducing cooling system energy consumption. The heated water then enters the chiller or goes through a natural cooling process and is recirculated back to the coil. The natural cooling process uses ambient air to cool the water and consumes much less energy. To save energy, data centers are usually built in cooler areas to achieve natural cooling. But due to advances in electronic technology, many IT servers are already allowed to operate at higher temperatures above 30°C. This means that in most climates, including those in hotter areas, data centers can also be expected to benefit from natural cooling. Researchers have built a model based on traditional cooling systems to simulate the operating status of the system under different climate conditions.

[0014] Before raising the temperature threshold, however, three things must be ensured. First, server reliability must be ensured; second, computing efficiency must remain unchanged; and third, server energy consumption must not increase due to the activation of built-in cooling mechanisms, such as fans. The next generation of servers may be able to operate at temperatures as high as 40°C without performance degradation. Data center operating temperatures of 41°C are achievable in the near future.

[0015] Data centers are "sea-connected" and "heat-averse," especially when large numbers of servers are clustered together. The heat generated must be dissipated promptly, otherwise the data center will experience operational failures due to heat dissipation issues. With the unbearable summer heat, ocean-based data center cooling has become a new approach.

[0016] Among the many data center cooling technologies being explored, submarine data centers are undoubtedly the most innovative. Subsea data centers are a new, green and low-carbon data center solution, offering a range of unique advantages in energy, land, and water conservation, low latency, high computing power, high security, high reliability, and rapid deployment. Subsea data centers can easily be combined with clean marine energy sources such as offshore wind power and wave power through intensive sea utilization, enabling the transformation of energy-intensive data centers into low-carbon or even zero-carbon ones.

[0017] In summary, the main problems faced by the existing technology are:

[0018] 1. Data centers consume a huge amount of electricity, consuming a large amount of electric energy and increasing a large amount of carbon emissions; 2. The instability of renewable energy power conflicts with the need for continuous, stable, reliable and safe power supply technology for data centers. As large electricity users, data centers face technical difficulties in using green electricity for power supply. Clean energy power supply is difficult to implement and realize, and there are great difficulties in building an "integrated source, grid, load and storage" power supply system; 3. The cooling and heat dissipation air conditioning of data centers consumes a lot of electricity and has low energy efficiency. The cooling and heat dissipation and energy-saving and emission reduction technologies are difficult; 4. The use of ocean cooling and heat dissipation for energy conservation and emission reduction faces the high pressure, sealing, and corrosion protection requirements of the data cabin of the submarine data center, high construction costs, and it is very difficult to enter and exit the submarine data cabin for operation and maintenance, resulting in extremely high operation and maintenance costs; 5. It is difficult to use wind power locally and export it externally, and the problem of wind abandonment has always been difficult to solve. In view of this, the present invention is proposed. Summary of the Invention

[0019] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a wind power tower data center, green energy storage power supply for data center, "source-grid-load-storage integration" of data center and wind power, energy-saving cooling and heat dissipation method and heat dissipation device.

[0020] To achieve the above object, the present invention provides the following technical solutions:

[0021] In one aspect, the present invention provides a wind turbine tower data center, comprising a multi-story data center computer room constructed from bottom to top in the interior space of a wind turbine pile foundation and / or tower using a modular prefabricated structure, wherein an elevator passage is provided in the center of the pile foundation and / or tower, connecting each floor of the data center computer room and allowing people and goods to pass through.

[0022] Each floor of the data center room is equipped with equipment racks and / or distributed energy storage cabins for installing data equipment and / or energy storage batteries and / or supercapacitors;

[0023] In each of the data center computer rooms, an air-cooled radiator is provided on the equipment rack and / or in the distributed energy storage cabin, and the data equipment and / or energy storage battery and / or supercapacitor may be equipped with a liquid cooling plate radiator.

[0024] Use wind power generation and / or energy storage batteries to provide stable and reliable power supply to data center equipment.

[0025] It should be noted that the energy storage batteries include centrally installed energy storage batteries and distributed installed energy storage batteries.

[0026] The internal space of the pile foundation and / or tower of the wind turbine is very large. By using the internal space to build a data center inside the pile foundation and / or tower, there is no need to build a data center site and factory building. It also isolates the data center equipment from the impact of pollution and corrosion from the external environment.

[0027] Specifically, the multi-story data center room formed by the layered installation of the modular preinstalled structure includes a room frame structure, and the room frame structure is composed of horizontal beams and columns supporting the horizontal beams, and the horizontal beams include radial beams (longitudinal) and arc beams (transverse) for fixing the radial beams (longitudinal); the modular preinstalled structure is installed and constructed in layers from bottom to top in the pile foundation and / or tower, and the beam segments and supporting column segments for building the data center room are sent in and out of the tower through the entrance and exit doors at the bottom of the tower, and the frame structure of the multi-story data center room is built in layers from the bottom to top in the tower, and the horizontal beams in the vertical direction between the lower and upper layers of the multi-story data center room of the frame structure are supported by columns; adjacent radial beams (longitudinal) are fixed by arc beams (transverse), and the radial beams (longitudinal) are abutted against the flexible support pads on the inner wall of the pile foundation and / or tower, and flexible pressure contact force is used to reduce the vibration of the tower and transmit vibration energy through the room frame to the layered room to affect the equipment in the data center.

[0028] Specifically, fireproof shelves or bottom plates are provided between the floors of the multi-story data center rooms, and fireproof material plates or fireproof material cylinders are vertically provided at the center of the data center rooms to isolate and form elevator passages that run through from top to bottom. The elevator passages are provided with fire doors for entering and exiting the data center rooms on each floor, and the data center rooms on each floor can be reached through the elevators and the fire doors of the elevator passages.

[0029] On the other hand, the present invention provides a power supply method for a wind power tower data center, the specific method is as follows:

[0030] By utilizing the AC power generated by wind turbines on-site and converting it into DC power through AC / DC, the data center equipment is powered and the energy storage batteries are charged and stored. At the same time, energy storage batteries and / or supercapacitors are used to store wind power during abundant periods, and the DC power stored by wind power and / or energy storage batteries is used to provide stable, safe, continuous, reliable, green and carbon-free DC power supply to the data center. When the power of wind power generation and energy storage batteries is insufficient, the power transmission and transformation equipment of the large power grid is used to integrate wind power generation and send the power of the large power grid back to power the data center and charge the energy storage batteries. The large power grid provides support and backup power for the data center, ensuring that the power supply of the data center is stable, safe and reliable in the long term.

[0031] Preferably, the present invention converts the electricity generated by the wind turbine into AC / DC directly on-site in the pile foundation and / or tower, converting the green wind power into high-voltage direct current, and uses the high-voltage direct current to power the equipment in the data center and charge the energy storage battery.

[0032] Furthermore, the energy storage batteries can be distributedly installed in the energy storage cabins of the computer room on each floor of the data center, or they can be centrally installed in the space inside the pile foundation and / or the tower for centralized energy storage and battery power supply. The centrally installed energy storage batteries are also cooled and dissipated by air-cooled radiators and / or liquid-cooled plate radiators. The heat-conducting medium of the air-cooled radiator and / or liquid-cooled plate radiator also transfers the heat to the inner wall of the pile foundation and / or the tower, and the pile foundation and / or the tower transfer the heat to the seawater or air outside them.

[0033] In another aspect, the present invention provides a heat dissipation method for a wind power tower data center, the specific method is as follows:

[0034] The heat-conducting medium in the air-cooled radiator and / or liquid-cooled plate radiator transfers the heat generated by the data center equipment and / or energy storage batteries and / or supercapacitors to the inner wall of the pile foundation and / or tower, and conducts and dissipates the heat to the seawater and / or air outside the pile foundation and / or tower, thereby completing the cooling and heat dissipation of the data center equipment and / or energy storage batteries and / or supercapacitors; in offshore wind power, this cooling and heat dissipation method can achieve an "equivalent seawater" cooling and heat dissipation effect in an isolated marine environment and closed anti-corrosion state; the cooling and heat dissipation method of the present invention is energy-saving and environmentally friendly, saving the huge electricity consumption of air conditioning, refrigeration and heat dissipation in the data center (approximately 40% of the total energy consumption of the data center), can improve the energy efficiency of the data center, and is an important measure to achieve a green and carbon-free data center.

[0035] In another aspect, the present invention provides a cooling and heat dissipation device for a wind turbine tower-type data center, the cooling and heat dissipation device comprising a hollow body disposed within a pile foundation and / or a tower, an annular cylindrical interlayer formed between the exterior of the hollow body and the inner sidewall of the pile foundation and / or the tower, the upper and lower ends of the annular cylindrical interlayer being sealed by sealing bodies to form a closed space;

[0036] The heat dissipation device also includes a liquid collecting pipe with multiple inlets arranged around the lower end of the hollow body and extending into the annular cylindrical interlayer, and a spray pipe with multiple outlets arranged at the upper end of the hollow body; a submersible pump is provided between the liquid collecting pipe and the air-cooled radiator and / or the liquid-cooled plate radiator, and the heat dissipation device circulates heat through a heat-conducting medium to absorb and dissipate heat. After cooling in the annular cylindrical interlayer, the heat-conducting medium is pumped by the submersible pump and enters the air-cooled radiator and / or the liquid-cooled plate radiator from the liquid collecting pipe. After heat exchange, the heat-conducting medium whose temperature rises or evaporates and vaporizes is sprayed through the spray pipe to the corresponding pile foundation and / or the inner wall of the tower in the annular cylindrical interlayer for cooling, and the heat-conducting medium is cooled. The heat medium transfers the heat to the pile foundation and / or tower of the steel good thermal conductor. After the heat is transferred into the pile foundation and / or tower of the steel good thermal conductor, it will diffuse and transfer toward the upper and lower ends of the pile foundation and / or tower, thereby expanding the surface area of the pile foundation and / or tower for external heat dissipation. The pile foundation and / or tower acts as a radiator with a large surface area and can transfer a large amount of heat to the seawater or air outside. After the heat medium is cooled, condensed and dissipated by the pile foundation and / or tower, the temperature is reduced or it is condensed again into liquid, and is collected and stored in the liquid reservoir between the liquid collecting pipe and the submersible pump through the collecting pipe, thereby forming a continuous cycle of cooling and heat dissipation.

[0037] Specifically, a liquid reservoir for collecting the heat-conducting medium after its temperature is reduced is provided between the liquid collecting pipe and the submersible pump.

[0038] Specifically, the hollow body and the sealing body are both made of flexible materials, which facilitates transportation and installation in the pile foundation and / or tower of an already operational wind turbine generator set.

[0039] Specifically, the sealing body is an annular bead, and gas or liquid with sufficient pressure is filled into the annular bead to achieve sealing of the upper end and the lower end of the annular cylindrical interlayer.

[0040] On the last aspect, the heat dissipation device includes a cooler, which is arranged in water at the bottom of the pile foundation. The cooler is connected to an air-cooled radiator and / or a liquid-cooled plate radiator through a submersible pump. The heat dissipation device circulates heat through a heat-conducting medium to absorb and dissipate heat. After the heat-conducting medium performs heat exchange (absorbs heat) in the air-cooled radiator and / or the liquid-cooled plate radiator, the heat is transferred to the cooler, and heat exchange (cooling) is performed again with the water at the bottom of the pile foundation through the cooler. The cooled heat-conducting medium continues to circulate to the air-cooled radiator and / or the liquid-cooled plate radiator through the submersible pump for heat exchange (absorbs heat); the water at the bottom of the pile foundation conducts heat to the inner wall of the pile foundation, and the pile foundation conducts and dissipates the heat to the sea water or air outside, thereby completing the cooling and heat dissipation of the equipment in the data center computer room.

[0041] It should also be noted that the pile foundation and / or tower are generally made of steel, and are large-diameter, thick-walled steel tube structures. The excellent thermal conductivity of steel is used to dissipate heat in the data center inside the pile foundation and / or tower.

[0042] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0043] 1. This invention combines the data center with the interior space of the pile foundation and / or tower, saving the construction cost and investment of the data center computer room and site. By combining wind power with the data center inside the wind turbine tower to power it, and combining it with seawater cooling and heat dissipation technology and new energy storage technology, it can effectively solve the problem of huge power consumption in data centers, large-scale consumption of electricity and energy, and increased carbon emissions. It also solves the contradiction between the instability of renewable energy and the need for continuous, stable, reliable and safe power supply technology for data centers, and solves the technical difficulties of using green electricity for data centers as large electricity users. It also solves the difficulties of local wind power consumption and the technical difficulties of deep integration of green power supply and computing load of data centers as large electricity users. It achieves local wind power consumption and realizes green power supply with zero carbon emissions for data centers.

[0044] 2. The present invention utilizes the pile foundation and / or tower of the wind turbine generator set, and transfers the heat generated by the heating equipment and energy storage batteries of the data center to the pile foundation and / or tower through a heat-conducting medium. The pile foundation and / or tower transfers the heat to the seawater or air outside, thereby cooling and dissipating the heat of the heating equipment and energy storage batteries of the data center. In offshore wind power, this cooling and heat dissipation method can achieve an "equivalent seawater" cooling and heat dissipation effect in an isolated marine environment and a closed anti-corrosion state. The cooling and heat dissipation method is energy-saving and environmentally friendly, saving the huge electricity consumption of air conditioning, refrigeration and heat dissipation in the data center (approximately 40% of the total energy consumption of the data center), and can improve the energy efficiency of the data center. It is an important measure to achieve a green and carbon-free data center.

[0045] 3. This invention solves the difficulties of constructing, installing, operating, and maintaining submarine data centers, reducing construction costs. Compared to submarine data centers, this invention eliminates the need for an underwater sealed cabin, saving on the construction cost of a pressure-sealed cabin and shortening the construction period. Maintenance, inspection, and operation do not require diving, making access to and from the data center more convenient.

[0046] 4. The southeastern coastal urban clusters are developed and densely populated. Big data, cloud computing, smart cities, and digital lifestyles place enormous demands on data centers. Data centers are large electricity consumers, and due to power constraints, local development of data centers is impossible. Offshore wind power, with its short-distance transmission capacity and low cost, has developed rapidly in recent years. Offshore wind power is abundant, generating large amounts of wind power over a long period of time. This invention deeply integrates offshore wind power with data centers: data centers are built using the vast free space within wind turbine pile foundations and / or towers; data centers are powered by wind power and stored energy from energy storage batteries; and data centers are cooled and dissipated using the equivalent seawater cooling system of offshore wind turbine pile foundations and / or towers. This reduces data center site space and construction costs; reduces investment and operating costs for data center air conditioning and cooling; and achieves green, low-carbon, renewable energy power supply for data centers. By integrating data centers as large electricity consumers with green offshore wind power, this solves the problem of local offshore wind power consumption difficulties. This achieves local offshore wind power utilization and consumption, with data centers built and deployed close to users, green, low-carbon power supply, air conditioning-free seawater cooling, and energy-efficient and efficient operation.

The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present invention. Instead, they are merely examples consistent with some aspects of the present invention as detailed in the appended claims.

[0055] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0056] Example

[0057] This embodiment provides a wind turbine tower data center, which includes a multi-story data center computer room 3 formed by layered installation from bottom to top using a modular pre-assembled structure within the interior space of the wind turbine pile foundation and / or tower. An elevator passage is provided in the center of the pile foundation and / or tower, which runs through each floor of the data center computer room 3 and is used for the passage of people and goods.

[0058] Each floor of the data center room 3 is provided with equipment racks and / or distributed energy storage cabins for installing data equipment and / or energy storage batteries and / or supercapacitors;

[0059] Air-cooled radiators are installed in the data center computer room 3, equipment racks and / or distributed energy storage cabins on each floor, and the equipment and / or energy storage batteries and / or supercapacitors in the data center are equipped with liquid-cooled plate radiators; wind power generation and / or energy storage batteries are used to provide stable and reliable power supply to the equipment in the data center.

[0060] It should be noted that the energy storage batteries include centrally installed energy storage batteries and distributed installed energy storage batteries.

[0061] The internal space of the pile foundation and / or tower of the wind turbine is very large. By using the internal space to build a data center inside the pile foundation and / or tower, there is no need to build a data center site and factory building. It also isolates the data center equipment from the impact of pollution and corrosion from the external environment.

[0062] Specifically, the multi-story data center room 3 formed by the layered installation of the modular preassembled structure includes a room frame structure, which is composed of horizontal beams and columns supporting the horizontal beams. The horizontal beams include radial beams (longitudinal) and arc-shaped beams (transverse) for fixing the radial beams. The modular preassembled structure is installed and constructed in layers from bottom to top in the pile foundation and / or tower, and the beam segments and supporting column segments for constructing the data center room 3 are sent in and out of the tower through the entrance and exit doors at the bottom of the tower. The frame structure of the multi-story data center room 3 is built in layers from the bottom to the top in the tower. The horizontal beams in the vertical direction are supported by columns between the lower and upper layers of the multi-story data center room 3 of the frame structure. The radial beams (longitudinal) are evenly arranged toward the inner wall of the tower, avoiding the elevator passage. Adjacent radial beams are fixed by arc-shaped beams (transverse). The radial beams are in contact with the flexible support pads on the inner wall of the pile foundation and / or tower, and flexible pressure contact force is used to reduce the vibration of the tower from transmitting vibration energy through the room frame to the layered room to affect the equipment in the data center.

[0063] Specifically, the layers of the multi-layer data center room 3 are provided with fireproof layers or bottom plates, and the center position of the data center room 3 is vertically provided with a fireproof material plate or fireproof material cylinder to separate and form an elevator passage that runs through the upper and lower parts. The elevator passage is provided with a fire door for entering and exiting the data center room 3 on each floor. The data center room 3 on each floor can be reached through the fire doors of the elevator and the elevator passage. Figure 1 and 2 shown.

[0064] See also Figure 3 As shown, this embodiment also provides a power supply method for the wind power tower data center as described above, and the specific method is as follows:

[0065] By utilizing the AC power generated by wind turbines on-site and converting it into DC power through AC / DC, the data center equipment is powered and the energy storage batteries are charged and stored. At the same time, energy storage batteries and / or supercapacitors are used to store wind power during abundant periods, and the DC power stored by wind power and / or energy storage batteries is used to provide stable, safe, continuous, reliable, green and carbon-free DC power supply to the data center. When the power of wind power generation and energy storage batteries is insufficient, the power transmission and transformation equipment of the large power grid is used to integrate wind power generation and send the power of the large power grid back to power the data center and charge the energy storage batteries. The large power grid provides support and backup power for the data center, ensuring that the power supply of the data center is stable, safe and reliable in the long term.

[0066] Preferably, the present invention converts the electricity generated by the wind turbine directly into AC / DC on-site within the pile foundation and / or tower, converting the green wind power into high-voltage direct current, which is used to power the equipment in the data center and charge the energy storage battery.

[0067] Furthermore, the energy storage batteries can be distributedly installed in the energy storage cabins of the computer room 3 on each floor of the data center, or they can be centrally installed in the space inside the pile foundation and / or the tower for centralized energy storage and battery power supply. The centrally installed energy storage batteries are also cooled and dissipated by air-cooled radiators and / or liquid-cooled plate radiators. The heat-conducting medium of the air-cooled radiator and / or liquid-cooled plate radiator also conducts the heat to the pile foundation and / or the inner wall of the tower, and the pile foundation and / or the tower dissipates the conducted heat to the seawater or air outside them.

[0068] This embodiment also provides a heat dissipation method for a wind power tower-type data center, the specific method is as follows:

[0069] The heat generated by the equipment and / or energy storage batteries and / or supercapacitors in the data center is conducted to the inner wall of the pile foundation and / or tower through the heat-conducting medium in the air-cooled radiator and / or liquid-cooled plate radiator. The pile foundation and / or tower conducts and dissipates the heat to the seawater and / or air outside thereof, thereby completing the cooling and heat dissipation of the equipment and / or distributed energy storage batteries and / or supercapacitors in the data center. In offshore wind power, this cooling and heat dissipation method can achieve an "equivalent seawater" cooling and heat dissipation effect in an isolated marine environment and a closed anti-corrosion state; the cooling and heat dissipation method of the present invention is energy-saving and environmentally friendly, saving the huge electrical energy consumption of air conditioning, refrigeration and heat dissipation in the data center (approximately 40% of the total energy consumption of the data center), and can improve the energy efficiency of the data center. It is an important measure to achieve a green and carbon-free data center.

[0070] This embodiment further provides a heat dissipation device for a wind turbine tower-type data center, the heat dissipation device comprising a hollow body 401 disposed within a pile foundation and / or a tower, an annular cylindrical interlayer 4 being formed between the exterior of the hollow body 401 and the inner sidewall of the pile foundation and / or the tower, the upper and lower ends of the annular cylindrical interlayer 4 being sealed by sealing bodies 402 to form a closed space;

[0071] The heat dissipation device further comprises a collecting pipe 501 with multiple inlets arranged around the lower end of the hollow body 401 and extending into the annular cylindrical interlayer 4, and a spray pipe 601 with multiple outlets arranged at the upper end of the hollow body 404. An air-cooled radiator or a liquid-cooled plate radiator for heat exchange through a heat-conducting medium is provided between the collecting pipe 501 and the spray pipe 601. A submerged pump 7 is provided between the collecting pipe 501 and the air-cooled radiator and / or the liquid-cooled plate radiator. The heat dissipation device circulates heat through the heat-conducting medium to absorb and dissipate heat. After cooling in the annular cylindrical interlayer 4, the heat-conducting medium is pumped by the submerged pump 7 and enters the air-cooled radiator and / or the liquid-cooled plate radiator from the collecting pipe 501. After heat exchange, the heat-conducting medium whose temperature rises or evaporates and vaporizes is then discharged through the spray pipe 6. 01 is sprayed onto the inner wall of the corresponding pile foundation and / or tower in the annular cylindrical interlayer 4 to cool it down. The heat-conducting medium transfers the heat to the pile foundation and / or tower of the steel good thermal conductor. After the heat is transferred into the pile foundation and / or tower of the steel good thermal conductor, it will diffuse and transfer toward the upper and lower ends of the pile foundation and / or tower, thereby expanding the surface area of the pile foundation and / or tower for external heat dissipation. The pile foundation and / or tower acts as a radiator with a large surface area and can transfer a large amount of heat to the seawater or air outside it. After the heat-conducting medium is cooled, condensed and dissipated by the pile foundation and / or tower, its temperature is reduced or it is condensed again into liquid, and is collected and stored in the liquid reservoir between the liquid collecting pipe 501 and the submersible pump 7 through the collecting pipe 501, thereby forming a continuous cycle of cooling and heat dissipation.

[0072] Specifically, the submersible pump 7 is connected to the air-cooled radiator and / or the liquid-cooled plate radiator through a first pipe 5 , and the air-cooled radiator and / or the liquid-cooled plate radiator is connected to the spray pipe 601 through a second pipe 6 .

[0073] Specifically, the hollow body 401 and the sealing body 402 are both made of flexible materials, which facilitates transportation and installation in the pile foundation and / or tower of an already operational wind turbine.

[0074] Specifically, the sealing body 402 is an annular bead, and gas or liquid with sufficient pressure is filled into the annular bead to achieve sealing of the upper end and the lower end of the annular cylindrical interlayer 4.

[0075] This embodiment also provides a heat dissipation device for a wind turbine tower-type data center that is different from the above-mentioned heat dissipation device, including a cooler. The cooler is arranged in water at the bottom of the pile foundation. The cooler is connected to an air-cooled radiator and / or a liquid-cooled plate radiator through a submersible pump 7. The heat dissipation device circulates heat to absorb and dissipate heat through a heat-conducting medium. After the heat-conducting medium performs heat exchange (heat absorption) in the air-cooled radiator and / or the liquid-cooled plate radiator, it performs heat exchange (cooling and heat dissipation) with the water at the bottom of the pile foundation through the cooler. The cooled heat-conducting medium continues to circulate to the air-cooled radiator and / or the liquid-cooled plate radiator through the submersible pump 7 for heat exchange (heat absorption); the cooler at the bottom of the pile foundation transfers the heat generated by the equipment and / or energy storage battery of the data center to the water at the bottom of the pile foundation through the heat-conducting medium, and the water then transfers the heat generated to the inner wall of the pile foundation. The pile foundation then performs heat exchange with the seawater outside the pile foundation, thereby completing the cooling and heat dissipation of the equipment in the data center computer room 3.

[0076] It should also be noted that generally the pile foundation and / or tower are made of steel, and the excellent thermal conductivity of steel is used to achieve heat dissipation of the data center inside the pile foundation and / or tower.

[0077] The cooling and heat dissipation method of the present invention has multiple engineering implementation schemes. This embodiment can adopt two different heat dissipation methods, as follows:

[0078] The first method: high-temperature liquid or gaseous heat-conducting medium is sprayed around the inner wall of the pile foundation and / or tower through a multi-outlet spray pipe 601. The heat-conducting medium transfers the heat to the pile foundation and / or tower made of steel, which are good thermal conductors. After the heat is transferred into the interior of the pile foundation and / or tower made of steel, it diffuses and transfers toward the upper and lower ends of the pile foundation and / or tower, thereby expanding the surface area of the pile foundation and / or tower for external heat conduction and heat dissipation. The pile foundation and / or tower acts as a radiator with a large surface area, and can transfer and dissipate a large amount of heat to the seawater or air outside. After the heat-conducting medium is cooled, condensed, and dissipated through the pile foundation and / or tower, its temperature is lowered or it is recondensed into liquid. The liquid low-temperature heat-conducting medium is collected by a multi-inlet collecting pipe 501 around the inner wall of the pile foundation and / or tower below the spray pipe 601 and stored in a liquid reservoir (the multiple inlets of the collecting pipe 501 are distributed around the inner wall of the pile foundation and / or tower, and the position below the spray pipe 601 is convenient for collecting the heat-conducting medium). The liquid low-temperature heat-conducting medium is then returned to the air-cooled radiator and / or liquid-cooled plate radiator configured for various heating devices through its own gravity or by a submerged pump 7, for reciprocating cooling and heat dissipation. This achieves cooling and heat dissipation of various heating devices and energy storage batteries in the pile foundation and / or tower data center of the wind turbine.

[0079] In this embodiment, since the internal space of the pile foundation and / or the tower is too large, the heat-conducting medium for cooling and dissipating heat cannot contact the inner wall surface of the pile foundation and / or the tower over a large area for a long time, and the heat of the heat-conducting medium cannot be transferred to the pile foundation and / or the tower in time, which affects the cooling and heat dissipation effect.

[0080] To improve cooling and heat dissipation, a hollow body 401 can be installed within the tower / pile foundation. An annular cylindrical interlayer 4 is formed between the outer wall of this hollow body 401 and the inner wall of the tower / pile foundation. The upper and lower ends of this annular cylindrical interlayer 4 are sealed by sealing bodies 402. Sealing bodies 402 utilize an annular bead inflated with air or hydraulic pressure, utilizing air or hydraulic pressure for flexible pressure contact, positioning, securing, sealing, and installation. The multiple inlets of the manifold 501 and the multiple outlets of the spray pipe 601 are both connected to the interior of the annular cylindrical interlayer 4. Through heat exchange, the heat generated by the data center's heat-generating devices and energy storage batteries during operation is transferred to the heat-conducting medium within the air-cooled radiator and / or liquid-cooled plate radiator. The heat-conducting medium is heated, causing it to heat up or evaporate and vaporize. The high-temperature liquid or gaseous heat-conducting medium is sprayed through the spray pipe 601 onto the inner wall of the pile foundation and / or tower corresponding to the annular cylindrical interlayer 4. The heat-conducting medium then transfers the heat to the pile foundation and / or tower, which are good thermal conductors. The pile foundation and / or tower, acting as a large-surface radiator, can transfer a large amount of heat to the seawater or air outside the pile foundation and / or tower. After the heat-conducting medium is cooled, condensed, and dissipated by the pile foundation and / or tower, its temperature drops or it condenses into a liquid state. The low-temperature liquid heat-conducting medium is collected by the liquid collecting pipe 501 and stored in a liquid reservoir. The low-temperature liquid heat-conducting medium is then pumped by the submersible pump 7 to the air-cooled radiator and / or liquid-cooled plate radiator configured for various heat-generating devices, performing continuous circulation cooling and heat dissipation. Cooling and dissipating heat from various heat-generating devices and energy storage batteries in the pile foundation / tower data center of the wind turbine. Heat dissipation and cooling of heat-generating devices within enclosed pile foundations and / or towers ensures long-term and safe operation of the equipment.

[0081] The second method: offshore wind turbines can also dredge and seal the basic sea mud layer in the pile foundation to isolate the marine sediments and the marine environment, purify the seawater in the pile foundation according to the requirements of water cooling and heat dissipation, use the purified water as the heat transfer medium, and use a submersible pump in the pile foundation to pump the heat transfer medium (water) to the air radiator and / or liquid cooling plate radiator configured for various heating equipment and energy storage batteries, etc. The heat transfer medium exchanges heat therein and then transfers the heat generated to the surrounding inner wall of the pile foundation. The pile foundation is used as a radiator to conduct and dissipate the heat to the seawater outside the pile foundation, thereby realizing the cooling and heat dissipation of various heating equipment with water.

[0082] Wind turbine pile foundations and / or towers are very tall, resulting in high lift and energy consumption for submersible pumps. Using water as a heat transfer medium for water cooling also presents some challenges. To save energy from submersible pumps and avoid the adverse effects of water cooling on air-cooled radiators and / or liquid-cooled plate radiators, a cooler can be placed in the water within the pile foundation. A heat transfer medium B, which is superior to water, can be used for heat exchange in the air-cooled radiators and / or liquid-cooled plate radiators installed in various heat-generating devices, transferring heat to heat transfer medium B. Heat transfer medium B then carries the heat through pipes to the cooler, which transfers the heat to the water within the pile foundation. Water, acting as heat transfer medium A, then transfers the heat to the inner wall of the pile foundation, using the pile foundation as a radiator to transfer the heat to the seawater outside the pile foundation. Heat transfer medium B is then returned from the cooler to the air-cooled radiator and / or liquid-cooled plate radiator, completing a closed circulation of heat transfer medium B, cooling and dissipating heat for the various heat-generating devices.

[0083] It should also be noted that Figure 4 It is a schematic diagram of the installation of the heat dissipation device in the tower 1; the pile foundation and / or tower includes the case where the internal space of the pile foundation is used alone, the interior of the tower alone, and the internal spaces of the pile foundation and the tower are used in combination; the radiator 2 includes an air-cooled radiator, a liquid-cooled plate radiator, and the case where the air-cooled radiator and the liquid-cooled plate radiator are used in combination.
