Description

Technical field [0001] The invention relates to the field of engineering thermophysics, in particular to an electric heating simulation heat source of a universal isotope heat source. Background technique [0002] Radioisotope Power System (RPS) is a system that converts the heat energy of isotope decay into electrical energy. At present, all systems based on the principle of static thermoelectric conversion (thermoelectric power generation) are collectively called Radioisotope Thermoelectric Generator (RTG). In academic exchanges and project implementation, my country usually refers to these devices as isotopic power sources, or nuclear power sources. Isotope power supply (heat source) has the characteristics of small size, high specific power, long service life, strong environmental applicability, and high reliability. It is suitable for special application scenarios such as deep space, deep sea, and remote land, and has an irreplaceable role. [0003] Isotope power source does...

Problems solved by technology

[0006] In general, the existing electric heating simulation heat source and the real isotope heat source are not equivalent to the real isotope heat source in terms of internal structure, heat distribution and temperature distribution.

In view of the above problems, in order to meet the equivalence requirements of the electric heating simulation heat source in the development and testing process of the isotope power source in my country's deep space exploration mission, keep the characteristics consistent with the real isotope heat source as far as possible, and meet the non-nuclear unit equivalent of the isotope power source system. In order to solve the problem of poor equivalence between the electric heating simulation heat source and the real isotope heat source existing in the prior art, it is imperative to develop an electric heating simulation heat source with high equivalence.
