Abstract: In this paper, the WRe3 heater is used to radiantly heat the molybdenum emitter in the thermionic energy converter. Firstly, the power loss of the emitter is calculated using numerical simulation. Secondly, the curve relationship between the heat power and the temperature is tested experimentally. The surface load of the heater in the experiment is analyzed. Suggestions for reducing the heater deformation and optimizing the experiment are put forward. This research has certain guiding significance for future experiments.

Key words: thermionic converter, molybdenum emitter, heater, heat radiation
