Description

Technical Field

[0001] The present invention belongs to the technical field of lunar-based thermovoltaic power generation, and in particular relates to a lunar-based in-situ photovoltaic-thermovoltaic power generation system with no external power source and continuous day and night operation. Background Art

[0002] The Moon, the closest natural celestial body to Earth, is a vital outpost for human exploration of the universe. Exploring the Moon is of great significance to scientific research, technological innovation, deep space exploration, and international cooperation, and can promote the progress and development of human society.

[0003] A sustained and stable energy supply is a key factor in establishing a lunar base and expanding the scale of lunar exploration. At the lunar equator, for example, a lunar day (approximately 27.3 Earth days) is divided equally by day and night (approximately 13.6 Earth days). As latitude increases, the duration of lunar night increases accordingly. To sustain lunar-based activities during the lunar night, new energy supply equipment and systems must be developed to ensure a continuous and stable energy supply. Currently, solar panels are a common energy source for lunar exploration, providing a stable energy supply for lunar-based activities during the lunar day. However, the energy collected and stored by solar panels during the lunar day is limited, making it difficult to maintain continuous exploration activities during the lunar night.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figures 1 to 3 The present invention discloses a photovoltaic-thermovoltaic day-night continuous lunar-based in-situ power generation system without external power, comprising a photovoltaic power generation unit for generating electricity during the lunar day and a thermovoltaic power generation unit for generating electricity during the lunar night. Both the photovoltaic power generation unit and the thermovoltaic power generation unit transmit electrical energy to the lunar base via an electrical energy transmission unit.

[0029] The thermovoltaic power generation unit includes a heat collecting device, a heat storage device, a hot-end heat transfer device, a thermoelectric module 6, and a cold-end heat transfer device. The thermoelectric module 6 is electrically connected to the power transmission unit.

[0030] The heat collection device collects heat during the lunar day and stores the heat in the heat storage device. During the lunar night, the hot-end heat transfer device transfers the heat stored in the heat storage device to the hot end of the thermoelectric module 6, and the cold-end heat transfer device transfers the heat from the cold end of the thermoelectric module 6 to the lunar surface, causing a temperature difference between the cold end and the hot end of the thermoelectric module 6, and the thermoelectric module 6 generates electricity.

[0031] In one feasible solution, the heat collecting device includes a tracking mirror 31 and a focusing mirror 34 arranged corresponding to the tracking mirror 31. A reflector 33 is arranged between the focusing mirror 34 and the tracking mirror 31. The reflector 33 is arranged corresponding to the focusing mirror 34, and the reflector 33 reflects solar radiation to the heat storage device.

[0032] In a feasible solution, a shutter 32 is provided between the tracking mirror 31 and the condensing mirror 34 . The shutter 32 is located between the reflective mirror 33 and the tracking mirror 31 . The shutter 32 is used to control the amount of radiation incident on the condensing mirror 34 .

[0033] In one feasible solution, the heat storage device includes a modified lunar rock heat storage layer 42, which is located on the radiation reflection path of the reflector 33. An in-situ lunar rock insulation layer 41 is provided on the outside of the modified lunar rock heat storage layer 42.

[0034] In a feasible solution, the hot end heat transfer device includes a heat pipe-heat storage block 51, which is arranged below the modified lunar rock heat storage layer 42, and the heat-taking end of the heat pipe-heat storage block 51 extends into the modified lunar rock heat storage layer 42. The heat-releasing end of the heat pipe-heat storage block 51 is in contact with a hot end heat spreader 52, and a number of hot end capillary heat pipes 53 are provided in the hot end heat spreader 52. A number of hot end heat transfer pipes 54 are buried in the hot end heat spreader 52, and the part of the hot end heat transfer pipe 54 extending out of the hot end heat spreader 52 is buried in the hot end heat spreader 55, and the hot end heat spreader 55 is arranged in contact with the hot end of the thermoelectric module 6.

[0035] Heat transfer path: The heat pipe-heat storage block 51 is in an ascending state. Its evaporation section is completely embedded in the modified lunar rock heat storage layer 42. Heat is transferred to the working fluid through the inner wall of the heat pipe, and the working fluid evaporates due to the heat. The gaseous working fluid liquefies and releases heat in the condensation section, and the heat is transferred to the heat storage block through the working fluid. When the temperature of the heat storage block reaches the set value, the heat pipe-heat storage block 51 descends and contacts the hot end heat spreader 52. The hot end heat spreader 52 relies on its own high thermal conductivity and the embedded hot end capillary heat pipe 53 to quickly and evenly transfer heat. The hot end heat transfer pipe 54 embedded in the hot end heat spreader 52 serves as the evaporation section, absorbing heat from the heat spreader and transferring heat to the condensation section above through the gas-liquid phase transition of the working fluid and capillary action. The condensation section is in close contact with the hot end heat spreader 55, achieving rapid and uniform heat transfer to the hot end heat spreader 55, providing a heat source for the thermoelectric module 6.

[0036] In a feasible solution, the cold end heat transfer device includes a cold end heat equalizing block 76, which is arranged in contact with the cold end of the thermoelectric module 6. A plurality of cold end heat transfer tubes 75 are buried in the cold end heat equalizing block 76. The part of the cold end heat transfer tube 75 extending out of the cold end heat equalizing block 76 is buried in the cold end heat equalizing plate 73. A plurality of cold end capillary heat pipes 74 are opened in the cold end heat equalizing plate 73. A cold end gravity heat pipe 72 is buried in the cold end heat equalizing plate 73. The top end of the cold end gravity heat pipe 72 passes through the cold end heat equalizing plate 73 and is connected to a radiation heat exchanger 71. The radiation heat exchanger 71 is set on the lunar surface.

[0037] Heat is transferred from the hot end of the thermoelectric module 6 to its cold end in the form of heat conduction, and is transferred to the evaporation section of the cold end heat transfer tube 75 through the cold end heat equalizer block 76; the heat is transferred to the condensation section of the cold end heat transfer tube 75 through the gas-liquid phase transition of the working fluid and capillary action; the condensation section is in close contact with the cold end heat equalizer block 76, and the cold end heat equalizer plate 73 relies on its own high thermal conductivity and the cold end capillary heat pipe 74 embedded in the plate to quickly and evenly transfer heat; the heat is then transferred to the evaporation section of the cold end gravity heat pipe 72, and through the gas-liquid phase transition of the working fluid, the heat is transferred from the evaporation section to the condensation section; the heat in the condensation section is transferred to the radiation heat exchanger 71 by heat conduction, and the radiation heat exchanger 71 transfers the heat to deep space in the form of thermal radiation, causing its temperature to drop to minus 180 degrees Celsius or even lower.

[0038] The heat transfer method of the hot-end capillary heat pipe 53, the hot-end heat transfer pipe 54, the cold-end gravity heat pipe 72, the cold-end capillary heat pipe 74, and the cold-end heat transfer pipe 75 is mainly achieved through capillary action in the pipes and the gas-liquid phase transition of the working fluid. The heat pipe relies on capillary action to transport the liquid working fluid. The liquid working fluid absorbs heat and evaporates in the high-temperature section. The gaseous working fluid carries the heat and quickly moves to the low-temperature section, where it releases heat and condenses into a liquid working fluid. The liquid working fluid adheres to the capillary wall and flows back to the high-temperature section through capillary action, thus circulating heat. In addition to relying on capillary action and the gas-liquid phase transition of the working fluid, the hot-end heat transfer pipe 54 and the cold-end gravity heat pipe 72 also use gravity to accelerate the downward movement of the liquid working fluid. Although the gravity on the moon is only one-sixth of that on Earth, the gravity effect is relatively small, it can still improve the working fluid return efficiency in specific heat transfer paths. The heat transfer method of the hot end heat spreader 52, the hot end heat spreader block 55, the cold end heat spreader 73 and the cold end heat spreader block 76 mainly relies on their own high thermal conductivity and high specific heat capacity characteristics; at the same time, the embedded heat pipe further realizes rapid and uniform heat transfer through capillary action and gas-liquid phase transition of the working fluid.

[0039] The heat pipe-heat storage block 51 is tightly embedded in the heat storage block. Each heat pipe-heat storage block 51 unit consists of three rows of heat pipes arranged in a plum blossom pattern, with 5, 4, and 5 heat pipes in each row, respectively. When the heat pipe-heat storage block 51 is in an ascending state, multiple groups of heat pipes can quickly transfer heat from the modified lunar rock heat storage layer 42 to the heat pipe portion. The capillary action of the heat pipe inner wall moves the liquid working fluid. The heat pipe evaporation section transfers heat to the working fluid, causing it to evaporate. Under the action of gas pressure, the gaseous working fluid moves to the condensation section near the heat storage block, releasing heat and liquefying. The heat pipe condensation section absorbs heat and transfers it to the heat storage block. The heat storage block, relying on its high thermal conductivity and high specific heat capacity, heats up and absorbs heat until it reaches the set temperature. Subsequently, the heat pipe-heat storage block 51 descends, transferring heat to the hot end heat sink 52 below. Because the gravity on the moon is only one-sixth of that on Earth, the energy consumption during the ascending and descending process of the heat pipe-heat storage block 51 is relatively low.

[0040] The temperature difference between the hot end heat equalizing block 55 in the hot end heat transfer device and the cold end heat equalizing block 76 in the cold end heat transfer device at both ends of the thermoelectric module 6 is used to generate electricity. In order to ensure that heat is mainly conducted between the hot end heat equalizing block 55, the thermoelectric module 6 and the cold end heat equalizing block 76, a heat insulation design is adopted between the hot end heat equalizing plate 52 and the cold end heat equalizing plate 73 and the cold end heat equalizing block 76 to prevent heat loss; each temperature difference power generation unit adopts a "sandwich" structure, that is, a hot end heat equalizing block 55 is sandwiched between two cold end heat equalizing blocks 76, and a group of thermoelectric modules 6 are inserted between each two heat equalizing blocks; this structure can fully utilize the temperature difference between the hot end heat equalizing block 55 and the cold end heat equalizing block 76, thereby improving the power generation efficiency of the thermoelectric module 6.

[0041] In one feasible solution, the photovoltaic power generation unit includes a photovoltaic panel 1 disposed on the lunar surface, and the photovoltaic panel 1 is electrically connected to a photovoltaic cell 2 .

[0042] In one feasible solution, the power transmission unit includes an inverter 8 electrically connected to the photovoltaic cell 2 and the thermoelectric module 6. The inverter 8 is electrically connected to a high-voltage tower 9, which transmits electricity to the lunar base.

[0043] In one feasible solution, the hot end heat transfer tube 54 is configured to be L-shaped.

[0044] In one feasible solution, the cold end heat transfer tube 75 is configured to be L-shaped.

[0045] The hot end heat transfer tube 54 and the cold end heat transfer tube 75 are both set to be L-shaped, and the evaporation section of the cold end heat transfer tube 75 is embedded in the cold end heat soaking block 76, and the condensation section is embedded in the cold end heat soaking plate 73. The evaporation section of the hot end heat transfer tube 54 is embedded in the hot end heat soaking plate 52, and the condensation section is embedded in the hot end heat soaking block 55, so that the cold end heat transfer tube 75 has a larger contact area with the cold end heat soaking block 76 and the cold end heat soaking plate 73, and the hot end heat transfer tube 54 has a larger contact area with the hot end heat soaking plate 52 and the hot end heat soaking block 55, thereby achieving better heat transfer effect.

[0046] Specific workflow: During lunar daytime, solar radiation shines on photovoltaic panel 1, which generates electricity and transmits it to photovoltaic cell 2. This electricity is then converted by inverter 8 and transmitted to the lunar base via high-voltage tower 9 to provide power for the lunar base. At the same time, solar radiation shines on tracking mirror 31. Due to the rotation of the moon, the incident angle and altitude of the sunlight change over time. Tracking mirror 31 adjusts its angle in real time to ensure that the solar radiation always shines on concentrator 34. Concentrator 34 converges the solar radiation to a point and shines it on reflector 33. Reflector 33 reflects the solar radiation to modified lunar rock heat storage layer 42 for heat storage. At noon or other special periods, shade 32 can be moved up and down to adjust the intensity of the thermal radiation reflected from tracking mirror 31 to concentrator 34, thereby controlling the amount of heat stored.

[0047] The lunar rock and lunar soil on the lunar surface have extremely low thermal conductivity, making them a natural thermal insulation material. They can be used directly as an in-situ lunar rock thermal insulation layer 41, effectively reducing heat loss to the external environment. Physical or chemical modification can be used to increase the thermal conductivity and specific heat capacity of lunar rock, turning it into a modified lunar rock heat storage layer 42, which can store the accumulated heat.

[0048] During the moonlit night, the heat pipe-heat storage block 51 is in its ascending phase, with its evaporation section completely embedded in the modified lunar rock heat storage layer 42, absorbing heat and transferring it to the heat storage block. When the temperature of the heat storage block reaches the set value, the heat pipe-heat storage block 51 descends, contacts the hot-end soaking plate 52, and conducts heat to the hot-end soaking plate 52. The hot-end soaking plate 52 transfers heat quickly and evenly through its own thermal conductivity and the embedded hot-end capillary heat pipe 53. The evaporation section of the hot-end heat transfer pipe 54 is embedded in the hot-end soaking plate 52, and the condensation section is embedded in the hot-end soaking block 55. Through the gas-liquid phase transition of the working fluid and capillary action, heat is transferred to the hot-end soaking block 55, providing a heat source for the thermoelectric module 6.

[0049] The radiation heat exchanger 71 is activated, transferring heat to deep space through radiation heat dissipation, reducing its temperature to minus 180 degrees Celsius or even lower; the radiation heat exchanger 71 is tightly connected to the condensing section of the cold-end gravity heat pipe 72, and the evaporation section of the cold-end gravity heat pipe 72 is embedded in the cold-end heat spreader 73, transferring heat from the evaporation section to the condensing section through the working fluid; the cold-end heat spreader 73 is embedded with the cold-end capillary heat pipe 74, and the two work together to achieve rapid and uniform heat transfer; the evaporation section of the cold-end heat transfer pipe 75 is embedded in the cold-end heat spreader 76, and the condensation section is embedded in the cold-end heat spreader 73, and through capillary action and the gas-liquid phase transition of the working fluid, the heat in the cold-end heat spreader 76 is transferred to the cold-end heat spreader 73; the cold-end heat spreader 76 absorbs the heat from the cold end of the thermoelectric module 6, ensuring that the temperature of the cold end of the thermoelectric module 6 is stable at a low temperature, forming a temperature difference with the hot end to generate electricity; the generated electrical energy is converted into high-voltage electricity through the inverter 8, and then transmitted to the lunar base through the high-voltage tower 9.
