Abstract
In the working process of the Nuclear Electric Propulsion, it will generate much waste heat by the power conversion system due to inefficiencies in the thermal-to-electric conversion process. Therefore, how to improve the heat discharge capacity of radiant heat exchanger has become an essential part of the research of space nuclear reactor. In this paper, the correctness of the Monte Carlo Method is verified by the theoretical solution and the Monte Carlo method to calculate the result of the Perpendicular rectangles with a common edge. Monte Carlo Method is used for calculating the radiation shape factor of the radiator and established the radiation heat exchange network between the multi-surfaces to figure out the distribution of heat dissipated on the panel. By analyzing the influence of different positions and temperature on the radiator, some opinion of improving the radiator panels are put forward. These results can serve as a reference for the design of heat rejection subsystem in space nuclear reactors.
