Abstract

The invention relates to the field of engineering thermophysics, in particular to a simulation space environment test platform of a thermophotovoltaic isotope power source model machine, which comprises a vacuum system, a water-cooling heat dissipation system, an electric power input system, a wafer output system and a temperature monitoring system, the vacuum system is provided with a cavity, and the cavity is used for installing a to-be-tested system; the vacuum system can vacuumize the cavity, so that a 0.03 m<3> vacuum environment is formed in the cavity; the water-cooling heat dissipation system is communicated with the vacuum system, and constant low temperature in the cavity can be ensured; the electric power input system is arranged on the side surface of the to-be-tested system; and the temperature monitoring system is in communication paste with the to-be-tested system and is used for detecting the temperature of the to-be-tested system. According to the invention, a stable 3*10<-3> Pa to 10<-5 > Pa high-vacuum environment of a 0.03 m<3> cavity can be maintained, various performance tests of existing and future isotope thermophotovoltaic isotope power supply systems are met, and various performance changes are measured in real time.

Description

technical field [0001] The invention relates to the field of engineering thermophysics, in particular to a simulated space environment test platform for a thermal photovoltaic isotope power source prototype. Background technique [0002] The isotope thermophotovoltaic power supply (RTPV) system is a system that converts isotope decay heat energy into electrical energy in the form of light energy. The isotope thermal photoelectric power supply (RTPV) system is suitable for special application scenarios such as deep space, deep sea, and remote land, and has an irreplaceable role due to its advantages of long life, high conversion efficiency, high specific power, stability and reliability. [0003] From the perspective of planning, the isotope power supply is one of the core elements of the future development of deep space exploration. According to my country's development plan for deep space exploration, the interplanetary traversal will reach Uranus or beyond. At that time, ...
