Description

Technical Field

[0001] This invention relates to the field of combined technology of data centers and thermoelectric power generation, and specifically to a thermoelectric power generation system that combines the utilization of waste heat from data centers. Background Technology

[0002] In recent years, with the rapid increase in the number of data centers, the high energy consumption of data centers has become increasingly important. Data traffic will continue to expand in the future, and the number and scale of data centers will continue to grow rapidly. Therefore, it is essential to address the issues of high energy consumption and high carbon emissions in data centers. Currently, the two major challenges facing data centers are high energy consumption and difficulty in heat dissipation and cooling. Given the current reality of tight energy supply and unfavorable natural environment, it is necessary to consider combining green and new energy sources with the advantages of the natural environment to reduce the electricity and cooling costs of data centers. Research shows that 68% of the waste heat generated by data center electricity consumption can be recovered and utilized, indicating abundant waste heat resources. However, conventional applications such as building heating and heating domestic water require separate supporting facilities, are limited by seasonal application, and suffer from heat dissipation due to long-distance heat transfer. Furthermore, under current technological levels and natural environmental conditions, ocean thermal energy conversion (OTEC) has very low power generation efficiency due to the small temperature difference between the heat and cold sources, resulting in low economic benefits for single-system cycle power generation and lacking commercial development value. Therefore, it is urgent to research an OTEC power generation system that can utilize the waste heat from data centers. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a thermoelectric power generation system that combines the waste heat utilization of a data center. This system combines a data center system and a thermoelectric power generation system, which can generate electricity by utilizing the waste heat generated during the operation of the data center system while cooling the data center system.

[0006] A construction platform built on the sea surface is equipped with a data center system, a thermoelectric power generation system, and a central control system.

[0007] The thermoelectric power generation system is used to cool the data center system in operation and to generate electricity using the waste heat generated by the data center system during operation, with at least a portion of the generated electricity supplied to the data center system.

[0008] The central control system is communicatively connected to the thermoelectric power generation system and the data center system, and adjusts the cooling capacity and power generation of the thermoelectric power generation system according to the temperature during the operation of the data center system.

[0009] As described above, the combined data center waste heat utilization thermoelectric power generation system further includes multiple data warehouses, which are arranged in a matrix array extending in a three-dimensional direction on the construction platform to form multiple data warehouse groups. The thermoelectric power generation system and the central control system are placed on the platform at the top of the data warehouse groups. Cold water pipes for drawing deep-sea cold water are provided on the side of the data warehouse groups, and the deep-sea cold water drawn by the cold water pipes is used as the working fluid cold source of the thermoelectric power generation system.

[0010] The combined data center waste heat utilization thermoelectric power generation system described above further includes a turbine, a gas-liquid separator, and a condenser. The gaseous working fluid inlet of the gas-liquid separator is connected to the working fluid outlet of the data center system; the gaseous working fluid outlet of the gas-liquid separator is connected to the working fluid inlet of the turbine; the exhaust working fluid outlet of the turbine is connected to the inlet of the condenser; the chilled water pipe is connected to the condenser via a pipe equipped with a chilled water pump; and the liquid working fluid outlet of the condenser is connected to the working fluid inlet of the data center system.

[0011] As described above, the combined data center waste heat utilization thermoelectric power generation system further includes a liquid storage tank for temporarily storing the cooled and liquefied liquid working fluid. The liquid storage tank is installed on the pipeline connecting the liquid working fluid outlet of the condenser and the working fluid inlet of the data center system. A check valve is installed on the inlet pipeline of the liquid storage tank, and a working fluid pump is installed on the outlet pipeline of the liquid storage tank. A working fluid pump is also installed on the outlet pipeline of the condenser.

[0012] The thermoelectric power generation system for utilizing waste heat from a combined data center, as described above, further includes a gas tank for temporarily storing a gaseous working fluid. The gas tank is located on a pipeline connecting the gaseous working fluid inlet of the gas-liquid separator to the working fluid outlet of the data center system. The inlet pipeline of the gas tank is equipped with a one-way valve and a multiphase flow meter, and the outlet pipeline of the gas tank is equipped with a safety valve and a control valve.

[0013] In the aforementioned combined data center waste heat utilization thermoelectric power generation system, each of the data warehouses is further equipped with at least one working fluid flow pipe. The working fluid flow pipe is arranged for internal or external flow within the data warehouse, or for single-sided, combined, or local areas of the data warehouse. The working fluid flow pipe adopts a spiral, meandering, or hybrid spiral-meandering pipe arrangement.

[0014] In the aforementioned combined data center waste heat utilization thermoelectric power generation system, the data warehouse is further equipped with a temperature monitor and a humidity monitor, both of which are connected to the data center system control signals.

[0015] The combined data center waste heat utilization thermoelectric power generation system described above further includes a fixed support for fixing the construction platform, the top of which is connected to the construction platform and the bottom of which extends below the seabed mud surface.

[0016] As described above, the thermoelectric power generation system for utilizing waste heat from a combined data center further includes, as a working fluid, either a pure working fluid material or a non-azeotropic material.

[0017] Compared with existing technologies, the advantages of this invention are as follows: This invention combines data center systems and thermoelectric power generation systems to complement each other's strengths and weaknesses. On the one hand, it solves the problem of heat dissipation and cooling difficulties in data center systems; on the other hand, it addresses the problem of low power generation efficiency in thermoelectric power generation systems. Furthermore, it innovatively proposes using the liquid working fluid of the thermoelectric power generation system as the cooling material for the data center system. This can rapidly remove the high heat load of data center operations, maintaining the data center at a high-performance operating temperature. In addition, the waste heat removed during the data center cooling process is recovered and utilized in the thermoelectric power generation system, providing it with a high-temperature, stable heat source. This significantly increases the temperature difference between the cold and heat sources in the thermoelectric power generation system, increasing the system's power generation. The generated electricity can be directly used to meet the power supply needs of the data center, realizing the construction of a green, low-carbon integrated utilization system. This effectively expands the site selection range for the construction of such integrated utilization systems and promotes their commercial development. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] Example:

[0024] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, in the embodiments of this invention are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0025] It should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0026] In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. Furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0028] See Figures 1 to 2 This invention provides a thermoelectric power generation system 1 that utilizes waste heat from a data center. It may include: a construction platform 4 built on the sea surface, on which a data center system, a thermoelectric power generation system 1, and a central control system 2 are installed. The thermoelectric power generation system 1 is used to cool the operating data center system and utilizes the waste heat generated during operation to generate electricity, with at least a portion of the generated electricity supplied to the data center system. The central control system 2 is communicatively connected to the thermoelectric power generation system 1 and the data center system, and adjusts the cooling capacity and power generation of the thermoelectric power generation system 1 according to the operating temperature of the data center system.

[0029] Specifically, this embodiment utilizes the liquid working fluid of the thermoelectric power generation system 1 as the cooling material for the data center system. This fluid can rapidly remove the high heat load of the data center operation, maintaining the data center at a high-performance operating temperature. Simultaneously, the waste heat removed during the data center system's cooling process can be recovered and reused in the thermoelectric power generation system 1, providing it with a high-temperature, stable heat source. This significantly increases the temperature difference between the cold and heat sources in the thermoelectric power generation system 1, thereby increasing its power generation. The generated electricity can be directly applied to the data center's power supply needs, thus achieving the construction of a green, low-carbon integrated utilization system. This effectively expands the site selection range for the construction of such an integrated utilization system and accelerates its commercial development.

[0030] See you again Figure 1 , Figure 1 A thermoelectric power generation system 1 for the combined utilization of waste heat from a data center is demonstrated, which may include: a construction platform module 4, a data center module, and a thermoelectric power generation module.

[0031] Specifically, the function of the construction platform module 4 is to build a platform on the sea surface to house the data center system, the thermoelectric power generation system 1, and the central control system 2. The main structure of the construction platform module 4 includes the thermoelectric power generation system 1, the central control system 2, the data warehouse 3, the chilled water pipes 6, the construction platform 4, and the fixed support 5. The thermoelectric power generation system 1 cools the data center system and utilizes its waste heat. It uses a liquid working fluid to cool the data center system, absorbing the large amount of heat generated during the operation of the data center system. On the one hand, it maintains a suitable temperature for the high-performance operation of the data center equipment; on the other hand, the liquid working fluid vaporizes after being heated and is input into the turbine 38 to generate electricity. The central control system 2 regulates and monitors the overall system. By monitoring the operating temperature of the data center in real time, it rationally allocates the liquid working fluid input cooling rate, the gaseous working fluid output power generation rate, and the water pumping volume of the chilled water pipes 6, and receives the power generated by the thermoelectric power generation system 1 and distributes it to the data center applications. Furthermore, the data center system includes multiple data warehouses 3, each composed of several large data center racks. Each data warehouse 3 is an independent component, facilitating subsequent localized maintenance and replacement of aging parts. These warehouses are arranged in a matrix on the construction platform 4. The construction platform 4 is a frame structure housing the data center system, the thermoelectric power generation system 1, and the central control system 2. Located above sea level, the construction platform 4 resembles a rectangular frame structure, with multiple data warehouses 3 placed in the center. The thermoelectric power generation system and the central control system 2 are placed on the platform above the data warehouses, and cold water pipes 6 for drawing deep-sea cold water are located on the sides. Fixed supports 5 are used to secure the construction platform 4 and its mounted system structure. The fixed supports 5 extend below the seabed mud surface for stable support.

[0032] Understandably, the specific construction dimensions and scale of the platform 4 and fixed support 5 structures can be designed according to the actual needs of the project, and the tides, wave heights, seabed depths, geological characteristics, and other factors of the sea area where the construction site is located need to be taken into account.

[0033] The data center module serves as a specific network of devices for global collaboration in data processing, acceleration, computation, and storage. Its main structure includes multiple data bays (3), working fluid circulation pipes, and connecting and securing structures. Each data bay (3) is composed of multiple large data center racks, with each bay being an independent component for easy localized maintenance and replacement of aging parts. They are arranged in a matrix queue on the construction platform (4). Furthermore, the working fluid circulation pipes circulate liquid working fluid to each data bay (3) for equipment cooling. The connecting and securing structures securely mount the data bays (3) and working fluid circulation pipes, forming a compact matrix queue without affecting equipment operation, thus maximizing space efficiency.

[0034] Specifically, the number of server racks, rack layout, and dimensions of a single data warehouse 3 can be designed according to actual project requirements. Key parameters to consider include the optimal operating temperature of the data center, the heat generated by the server racks, the cooling effect of the liquid working fluid, and the working fluid vaporization rate, leading to a comprehensive system design. Each data warehouse 3 is equipped with temperature and humidity monitors for real-time monitoring of operating temperature and humidity. The working fluid circulation pipes can be installed inside or outside the data warehouse 3, and their specific placement can be on all six sides of the data warehouse 3, including single sides, combined sides, or localized areas. Specific considerations include the location of concentrated heat release, heat conversion efficiency, the flowability of liquid and gaseous working fluids, spatial layout design, and technological level. The data warehouse 3 can be arranged in a single column, single row, or multiple layers, or multiple columns, single rows, or multiple layers (e.g., multiple layers (height: Z), multiple rows (length: X), multiple columns (width: Y)). The arrangement is primarily determined by the temperature emitted by the data warehouse, the cooling capacity of the working fluid, and the degree of vaporization. A matrix arrangement extending in three dimensions is preferred, i.e., a matrix arrangement in the length, width, and height directions. The working fluid flow pipes can employ spiral, meandering, or hybrid spiral-meandering pipe layouts to extend the working fluid flow time and increase the heat exchange area, thereby maximizing heat transfer and ensuring that the liquid working fluid is completely vaporized into a gaseous state after flowing through the data warehouse 3.

[0035] See Figure 2The thermoelectric power generation module utilizes the waste heat of the data center system to generate electricity. The liquid working fluid is input into the data center system to cool it. The high-temperature gaseous working fluid after being heated and vaporized is input into the turbine 38 for power generation. The exhaust gas working fluid after power generation is condensed in the condenser 8 using cold seawater. The liquefied liquid working fluid after being cooled is reused as the coolant for the data center system in the next cycle.

[0036] A data center system may include multiple data warehouse groups; this embodiment uses three data warehouse groups as an example. Figure 2 As shown, the main structure of the thermoelectric power generation module includes a chilled water pipe 6, a chilled water pump 7, a condenser 8, a gas-liquid separator 37, a turbine 38, a fourth working fluid pump 9 connected to the condenser 8, a first check valve 10, a first liquid storage tank 13, a first multiphase flow meter 22, a first check valve 25, a first gas tank 28, a first safety valve 31, a first control valve 34, and a first working fluid pump 16 connected to the first data compartment group 19; a second check valve 11, a second liquid storage tank 14, a second multiphase flow meter 23, a second check valve 26, a second gas tank 29, a second safety valve 32, a second control valve 35, and a second working fluid pump 17 connected to the second data compartment group 20; and a third check valve 12, a third liquid storage tank 15, a third multiphase flow meter 24, a third check valve 27, a third gas tank 30, a third safety valve 33, a third control valve 36, and a third working fluid pump 18 connected to the third data compartment group 21.

[0037] Specifically, the cold water pipe 6 is used to draw deep cold seawater to provide a cold source for the thermoelectric power generation system 1. The cold water pipe 6 is attached to the outside of the construction platform 4 and lowered into the deep sea area. The specific depth needs to be determined based on the cold source temperature requirements and the seawater temperature. The cold water pump 7 is used to draw cold seawater and needs to be selected with a large power output that can meet the cold water supply requirements of the thermoelectric power generation system 1. The condenser 8 is used for heat exchange between the waste gas working fluid and the cold seawater, condensing the working fluid into a liquid state. The working fluid pump is used to transfer the liquid working fluid to the required equipment. The fourth working fluid pump 9, located between the condenser 8 and the storage tank, pumps the liquid working fluid into multiple storage tanks. The working fluid pump located on the connection path between the storage tanks and the data warehouse group pumps the liquid working fluid into multiple data warehouses 3. A check valve is used to limit the direction of liquid working fluid transmission, preventing backflow and ensuring that the liquid working fluid output from condenser 8 can be stably transmitted to multiple storage tanks. The check valve is located on the connection path between the working fluid pump and the storage tanks. The storage tanks store the cooled and liquefied liquid working fluid, further ensuring complete liquefaction and preventing the working fluid pump after the storage tank from running dry. This ensures that the pumping speed of the working fluid in each cooling route can be adjusted as needed. Data warehouse groups are used for cooling zoning. Multiple data warehouses 3 are grouped according to actual engineering design requirements to form multiple cooling lines, achieving reasonable allocation of equipment and energy. The number of data warehouse groups can be set as needed. Multiphase flow meters are used to measure the vaporization level of the liquid working fluid after the cooling process, monitoring the gas-liquid two-phase ratio at the output end of the working fluid flow pipe of the data warehouse group in real time, and appropriately adjusting the pumping rate of the liquid working fluid to ensure that the input liquid working fluid can be completely vaporized upon heating. A one-way valve controls the flow direction of the gaseous working fluid, ensuring its smooth flow. The one-way valve is located on the connection path between the data warehouse assembly and the gas tank. The gas tank temporarily stores the gaseous working fluid, facilitating subsequent control of its transmission rate and volume. A safety valve ensures system safety; if the gas tank pressure reaches its maximum set value, the safety valve automatically opens to release gas, reducing the pressure to a reasonable range. Control valves control the transmission rate and volume of the gaseous working fluid. By controlling multiple control valves on various lines, the designed amount of gaseous working fluid is transmitted to the turbine 38 for power generation as needed, ensuring the continuity and stability of the gaseous working fluid rate and volume input to the turbine. The control valves are located on the connection path between the gas tank and the gas-liquid separator 37. The gas-liquid separator 37 separates any liquid components that may be present in the gaseous working fluid, ensuring that the gas entering the turbine 38 for power generation is pure gaseous working fluid. Turbine 38 is used for the power generation process. Gaseous working fluid enters the hub of the turbine 38 to rotate and drive the generator to generate electricity. The electricity obtained from the power generation process enters the central control system 2 to provide power for the operation of the combined system itself.

[0038] It is important to note that the sea area where the combined data center waste heat utilization thermoelectric power generation system 1 of this invention is constructed should possess characteristics such as stable seabed strata, low risk of marine disasters, and low seawater temperature. Furthermore, the configuration of the thermoelectric power generation system 1 and the cold water pipes 6 should be based on the actual engineering design and requirements, considering the number of data warehouse groups, the cooling and waste heat absorption capacity of the thermoelectric power generation system 1, and the temperature characteristics of the deep cold seawater in the sea area. Multiple separate thermoelectric power generation systems 1 should be set up as needed, and the data warehouse groups should be grouped accordingly. The specific number, pipe size, and lowering depth of the cold water pipes 6 should be rationally configured in conjunction with the thermoelectric power generation system 1 to maximize equipment and energy utilization, comprehensively considering the system's operating costs and power generation benefits. In addition, the working fluid of this power generation system should be selected from high-temperature application materials. This working fluid material should possess characteristics such as high calorific value per unit volume, non-toxicity and environmental friendliness, and good overall cycle performance, such as R245ca, R245fa, or other suitable pure working fluid materials and non-azeotropic materials.

[0039] In some embodiments, each system device and valve switch of the power generation system of the present invention is equipped with a corresponding sensor, and the data information can be remotely transmitted to the central control system 2, thereby ensuring that the central control system 2 can monitor the overall system operation status in real time and control the local area devices and valve switches in real time. In addition, the circulation lines of multiple data warehouse groups can be flexibly connected and disconnected to facilitate the daily maintenance and troubleshooting of the system.

[0040] To better understand the present invention, the implementation steps of the thermoelectric power generation system 1 for utilizing waste heat from a combined data center are described below.

[0041] First, a suitable sea area is selected as the construction area for the power generation system, and a stable system construction platform 4 and fixed support structure 5 are built. Multiple data warehouses 3 with the required matrix distribution are reasonably arranged in the middle area of ​​the construction platform 4, and are reasonably grouped according to the cooling and waste heat absorption capacity of the subsequent thermoelectric power generation system 1. The required thermoelectric power generation system 1 and central control system 2 are reasonably arranged in the upper platform area of ​​the construction platform 4, and a reasonable matching design is carried out according to the actual project. Cold water pipes 6 are laid on the side of the construction platform 4 to achieve structural fixation and stable lowering to the design depth.

[0042] The power generation system is then operated by injecting sufficient working fluid into the system and starting the cold water pump 7 to pump deep cold seawater into the condenser 8. The working fluid exchanges heat with the cold seawater, condensing into a liquid working fluid which is then pumped to storage tanks in multiple circuits. Check valves ensure the flow direction of the liquid working fluid. The liquid working fluid in the storage tanks is then pumped to the working fluid flow pipes in the data warehouse group for cooling the data center system. The liquid working fluid absorbs heat energy from the data warehouse 3, vaporizing into a gaseous working fluid which is then transported to a gas tank. A phase flow meter monitors the vaporization degree of the liquid working fluid in real time, and a one-way valve controls the flow direction of the gaseous working fluid. The gaseous working fluid in the gas tank is transferred to the gas-liquid separator 37 via a control valve for gas-liquid separation. The pure gaseous working fluid enters the turbine 38 for power generation, while the liquid working fluid is transferred to the waste gas working fluid circulation pipeline. A safety valve ensures the safety of the gas tank. After the turbine 38 performs the power generation process, the generated electricity is transmitted to the central control system 2 for system power supply. The waste gas working fluid output from the turbine 38 re-enters the condenser 8 for condensation and liquefaction, and then begins the next power generation cycle.
