Abstract

The simulation heat source comprises a shell, a supporting body, a radiator and a heating assembly, a containing groove is defined in the supporting body of the simulation heat source of the small-sized thermophotovoltaic system, and the supporting body and the shell are arranged and combined with a heating device to be arranged below the radiator. The lower side face of the radiator, the groove bottom of the containing groove and the groove wall of the containing groove can form a relatively-closed containing space in an enclosing mode, a heating device of the electric heating assembly is arranged in the containing space in a suspended mode, and by the adoption of the structural arrangement, contact between the heating device and other component materials is reduced, and the service life of the heating device is prolonged. According to the simulation heat source, mutual influence among parts of the simulation power source in the high-temperature stage can be reduced, unnecessary conduction heat leakage can be avoided, more heat energy can be supplied to the radiator, the simulation heat source can still have high energy density while being miniaturized, and the requirement for development of a related small-sized thermophotovoltaic power system is effectively met.
