Abstract

The invention relates to a modular electric heating simulation heat source for ETG. The modular electric heating simulation heat source comprises at least two stacked modules. The module comprises a module box and an electric heating unit arranged in the module box. The electric heating unit is wrapped with a heat insulation layer. The electric heating unit comprises a cladding, a coil holding threaded pipe and a resistance wire spiral coil. The coil holding threaded pipe is mounted in the cladding. The resistance wire spiral coil is installed in the coil maintaining threaded pipe, and the coil maintaining threaded pipe is provided with internal threads matched with the resistance wire spiral coil. The beneficial effects of the heat souorce are as follows: the spiral coil simulates the radioactive source for heating, it is guaranteed that the heat flow path of the electric heating unit and the heat flow path of the radioactive source fuel pellet single body are basically the same, surface temperature distribution is basically consistent, overall temperature distribution is also basically consistent, a radioactive source is replaced to test and verify the performance of the generator, early-stage research cost is greatly reduced, and the research progress is accelerated.

Description

technical field [0001] The invention belongs to the field of nuclear industry, and in particular relates to a modular electric heating simulation heat source for ETG. Background technique [0002] There is an urgent need for radioisotope thermoelectric generators in the field of deep space exploration. Among them, the radioactive isotope is the energy source of the generator. Among them, high-power generator sources require several thousand watts of radioactive sources. Such a large number of radioactive sources are designed as a modular structure, consisting of multiple modules stacked together. Since the radioisotope heat source is extremely expensive and extremely rare, there is not and cannot be enough radioisotope to serve it in the early stage of the generator research. Therefore, it is necessary to use a simulated heat source as a substitute for a radiation source to simulate its heat output to verify whether the design of the generator is reasonable and whether th...
