▎ 摘　　要

NOVELTY - The device has a heat exchange mechanism (4) comprising multiple first heat exchange tubes (4-1) and multiple second heat exchange tubes (4-2). Heat exchange is performed between a nuclear reactor (1) and the Stirling thermoelectric conversion mechanism (2) through multiple first heat exchange tubes. A near field thermal photovoltaic mechanism (3) is set in a radiation radiator (5). Heat exchange is performed between cold end of the Stirling thermoelectric conversion mechanism and the near field thermal photovoltaic mechanism through multiple second heat exchange tubes. The waste heat of the second heat exchange tube is radiated by the radiation radiator. USE - Multi-effect space power supply device combined with near field thermal photovoltaic system. ADVANTAGE - The device maximizes the heat energy of the space nuclear power source into electric energy, so that the whole conversion efficiency is greatly improved. The combination of the near field thermal photovoltaic mechanism and the Stirling thermoelectric conversion mechanism realizes the multi-effect utilization of energy, thus improving the power generation efficiency of the device. The device uses two-dimensional metamaterial with excellent radiation transmission characteristics, so as to improve the output efficiency of space power supply device static conversion. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation method of graphene two-dimensional preparation metamaterial for multi-effect space power supply device. DESCRIPTION OF DRAWING(S) - The drawing shows a structure schematic diagram of the multi-effect space power supply device combined with near field thermal photovoltaic system. 1Nuclear reactor 2Stirling thermoelectric conversion mechanism 3Near field thermal photovoltaic mechanism 3-1Selective radiator 3-2Photovoltaic battery plate 4Heat exchange mechanism 4-1First heat exchange tubes 4-2Second heat exchange tubes 5Radiation radiator 6Annular supporting plate 9Reflecting layer 10Shielding body
