Description

Technical Field

[0001] This invention belongs to the field of data center power transmission technology, and in particular to a clean energy superconducting power transmission and energy storage system for data centers. Background Technology

[0002] The rapid development of the big data industry, coupled with the support of 5G communication, has led to an ever-increasing demand for large-scale data centers. Data centers consume enormous amounts of energy, and even small improvements in efficiency can bring substantial economic and environmental benefits. Therefore, achieving energy-efficient design for stable data transmission presents a significant challenge in terms of energy conservation and consumption reduction.

[0003] Currently, data centers primarily use copper cable power transmission, air cooling, water cooling, and chemical batteries as their main construction framework for electrical transmission, cooling, and energy storage systems. However, cable losses, heat dissipation efficiency, and energy storage conversion rates impose additional burdens and instabilities on data center operations.

[0004] Specifically, data centers consume a large amount of electricity, and the Joule heat generated by traditional copper cable transmission reduces the efficiency of power energy utilization. Data center operation generates a lot of heat, which is usually dissipated by air conditioning or chiller units, but the heat transfer efficiency of air and water is not high. Chemical battery energy storage has low energy storage density per unit volume and low energy conversion efficiency. When the power line fails, the long-term power supply stability of chemical batteries is poor. The power transmission, heat dissipation and chemical battery energy storage devices have a large installed capacity and occupy a large space.

[0005] To address the above issues, there is an urgent need for a clean energy superconducting power transmission and storage system for data centers, which can achieve low power transmission loss, high heat dissipation efficiency, high energy storage conversion rate, and small footprint.

[0028] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0029] Example 1: As Figure 1As shown, a clean energy superconducting power transmission and storage system for data centers includes a superconducting cable and data transmission unit 1, a cooling and energy storage unit 2, and a data center and cold shield heat dissipation unit 3. The input end of the cooling and energy storage unit 2 is connected to the power grid via a transmission line 5, and an electrical control switch 7 is installed on the transmission line 5 between the power grid and the cooling and energy storage unit 2. The output end of the cooling and energy storage unit 2 is connected to the superconducting cable and data transmission unit 1 via a refrigerant delivery pipe 4. The input end of the superconducting cable and data transmission unit 1 is connected to a communication terminal via a data transmission line 6 and to the power grid via the transmission line 5. An electrical control switch 9 is installed on the transmission line 5 between the power grid end and the superconducting cable and data transmission unit 1. The output end of the superconducting cable and data transmission unit 1 is connected to the data center and cold screen heat dissipation unit 3. The output end of the data center and cold screen heat dissipation unit 3 is connected to the cooling and energy storage unit 2. The input end of the data center and cold screen heat dissipation unit 3 is connected to the electrical control switch 7 via the transmission line 5. An electrical control switch 8 is installed on the transmission line 5 between the data center and cold screen heat dissipation unit 3 and the electrical control switch 7. The electrical control switch 8 is connected to the superconducting cable and data transmission unit 1 via the transmission line 5. This invention utilizes the superconducting cable and data transmission unit 1 to transmit urban power and information data to the data center. The superconducting optoelectronic composite cable places the clean energy liquid 121 and the superconducting conductor 122 in the same pipe. It utilizes the cooling capacity of liquid hydrogen or liquefied natural gas to achieve a superconducting state. The clean energy liquid 121 is circulated by forced flow, enabling lossless power transmission and timely removal of heat load. This achieves efficient transmission of optical communication, electrical energy, and clean energy, while saving space.

[0030] like Figure 1 and Figure 2 As shown, the refrigeration and energy storage unit 2 includes a gas generator set 21, a vaporizer 22, a superconducting energy storage and refrigerant tank 23, and a subcooling box 24. The subcooling box 24 is a stainless steel Dewar container, filled with clean energy liquid 121. The output end of the subcooling box 24 is connected to a refrigerant delivery pipe 4. The subcooling box 24 is connected to the superconducting energy storage and refrigerant tank 23. The output end of the superconducting energy storage and refrigerant tank 23 is connected to the vaporizer 22. The gas generator set 21 is connected to the vaporizer 22. The output end of the gas generator set 21 is connected to an electrical control switch 7. The electrical control switch 7 is connected to a superconducting magnet inside the superconducting energy storage and refrigerant tank 23 via a power transmission line 5. The superconducting energy storage and refrigerant tank 23 is made of stainless steel Dewar. On the one hand, it provides clean energy as refrigerant and fuel for the subcooled box 24 and the gas generator set 21. On the other hand, it cools the internal superconducting magnet and stores a large amount of electrical energy without damage. The vaporizer 22 converts the clean energy from liquid to gas. The gas generator set 21 converts the chemical energy of other clean energy fuels into electrical energy. Clean energy replenishment and fuel transportation are controlled by pipeline valves.

[0031] like Figure 1 and Figure 2 As shown, the clean energy liquid 121 in the subcooling chamber 24 is immersed without a chiller 241 and a cryogenic pump 242. The output end of the cryogenic pump 242 is connected to a refrigerant delivery pipe 4. The input ends of both the chiller 241 and the cryogenic pump 242 are connected to an electrical control switch 40. The electrical control switch 40 is connected to an electrical control switch 7 via a power transmission line 5. The chiller 241 is used to cool system heat leakage and the heat load generated by the data center, while the cryogenic pump 242 is used to provide the circulating power for the clean energy liquid system.

[0032] like Figure 1 and Figure 3 As shown, the superconducting cable and data transmission unit 1 includes electrical terminal 11, superconducting optoelectronic composite cable 12 and electrical terminal 2 13. Electrical terminal 11 and electrical terminal 2 13 are connected to both ends of the superconducting optoelectronic composite cable 12, respectively. Electrical terminal 11 is connected to electrical control switch 3 9, refrigerant conveying pipe 4 and data transmission line 6, respectively. Electrical terminal 2 13 is connected to electrical control switch 2 8 and data center and cold screen heat dissipation unit 3, respectively. The superconducting conductor 122 is cooled to a superconducting state by flowing clean energy liquid 121. It is connected by electrical terminal 11 and terminals (power and data). Both electrical terminal 11 and electrical terminal 2 13 are composed of cryogenic Dewars, realizing the connection transition between the room temperature conductor and the superconducting conductor 122, as well as the transition between room temperature and cryogenic temperature. Urban power is input on the power supply side. Electrical energy is input into the data center through electrical terminal 11, superconducting conductor 122, and electrical terminal 2 13. The optical signal of the data information is transmitted to the data center through the optical fiber bundle 123 in the superconducting optoelectronic composite cable 12. After storage and processing, the data information is returned to the outside through optical fiber. The clean energy liquid 121 flows from electrical terminal 11 to electrical terminal 2 13 and enters the data center and the cold screen heat dissipation unit 3.

[0033] like Figure 1 and Figure 6As shown, the data center and cold shield heat dissipation unit 3 includes a cold shield 31, a heat exchange coil 34, and a server 35. The cold shield 31 is installed outside the server 35, and the heat exchange coil 34 is installed on the cold shield 31. One end of the heat exchange coil 34 is connected to the refrigerant delivery pipe 4 on the electrical terminal 2 13, and the other end is connected to the subcooling box 24. The cold shield 31 is equipped with a power input terminal 32 and a data input terminal 33. The power input terminal 32 is connected to the electrical control switch 2 8 via a power transmission line 5, and the data input terminal 33 is connected to the electrical terminal 2 13 via a data transmission line 6. The space surrounding the data center server is enclosed by stainless steel to form the cold shield 31. The cold shield 31 is equipped with the power input terminal 32 and the data input terminal 33 for power supply and data information processing. Clean energy liquid 121 is arranged outside the cold shield 31 through the heat exchange coil 34. The heat load generated by the data center server is transferred to the cooling and energy storage unit 2 by the flowing clean energy liquid 121. The clean energy liquid 121 is either liquid hydrogen or liquefied natural gas.

[0034] Example 2: As Figure 4 As shown, the superconducting optoelectronic composite cable 12 includes a superconducting conductor 122, an optical fiber bundle 123, and a frame 124. The frame 124 has a tubular structure and is filled with a clean energy liquid 121. The superconducting conductor 122 and the optical fiber bundle 123 are disposed within the clean energy liquid 121. The simple structure of the frame 124 results in low manufacturing cost for the superconducting optoelectronic composite cable 12.

[0035] Example 3: As Figure 5 As shown, the superconducting optoelectronic composite cable 12 includes a superconducting conductor 122, an optical fiber bundle 123, and a second frame 125. The second frame 125 has a double-layered tube structure. The inner tube of the second frame 125 is filled with clean energy liquid 121, and the superconducting conductor 122 is placed inside the clean energy liquid 121. The optical fiber bundle 123 is arranged between the inner and outer tubes of the second frame 125. The second frame 125 evenly distributes the optical fiber bundle 123 through ribs between the inner and outer tubes. The optical fiber bundle 123 is not placed inside the clean energy liquid 121, which makes the superconducting optoelectronic composite cable 12 structurally strong and separates power transmission and signal transmission, allowing for separate power and signal maintenance and avoiding mutual interference after a single function of the superconducting optoelectronic composite cable 12 fails.

[0036] Example 4: Figure 7 and Figure 8 As shown, when the system is running normally, the city power supply supplies power to the data center and the server 35 in the cold screen heat dissipation unit 3 through the superconducting cable and the superconducting optoelectronic composite cable 12 in the data transmission unit 1. At the same time, the city power supply supplies power to the cooling and energy storage unit 2, so that the supercooling box 24 cools the clean energy liquid 121 and circulates it in a forced flow, providing a medium for the superconductivity of the superconducting optoelectronic composite cable 12.

[0037] Example 5: Figure 9 and Figure 10 As shown, when the power supply to the subcooling box 24 fails, the electrical control switch 7 is switched on, and the power supply to the subcooling box 24 is connected by the superconducting energy storage and refrigerant storage tank 23. The subcooling box 24 operates normally, the clean energy liquid 121 resumes circulation, and the server 35 operates normally.

[0038] Example 6: As Figure 11 and Figure 12 As shown, when the city power supply fails, electrical control switch 28 cuts off the city power supply and connects to the superconducting energy storage and refrigerant storage tank 23. Electrical control switch 17 connects to the superconducting energy storage and refrigerant storage tank 23, providing instantaneous power to the supercooled box 24 and the superconducting optoelectronic composite cable 12. Electrical control switch 17 connects to the gas generator set 21 to generate electricity and provide power to the server 35 through the superconducting optoelectronic composite cable 12.

[0039] Example 7: As Figure 10 As shown, when the city power supply fails to supply power to the superconducting optoelectronic composite cable 12, electrical control switch 2 8 and electrical control switch 3 9 cut off the power supply to the superconducting optoelectronic composite cable 12. The city power supply directly supplies power to the server 35 through the conventional line, and the clean energy liquid 121 continues to circulate to dissipate heat from the server 35.

[0040] Example 8: As Figure 11 As shown, when a short circuit in the city power supply causes a power outage in the superconducting optoelectronic composite cable 12, electrical control switches 8 and 9 cut off the city power supply and the power supply to the superconducting optoelectronic composite cable 12. Electrical control switch 7 is then connected to the superconducting energy storage and refrigerant storage tank 23 to provide instantaneous power to the server 35 and the subcooling box 24, respectively. Electrical control switch 7 is connected to the gas generator set 21 to generate electricity and provide power to the server 35.
