The invention discloses a multipurpose dual-mode
nuclear reactor power supply. One ends of a plurality of heat pipes are inserted into a
heat pipe reactor core, the other ends of the heat pipes penetrate through a shielding body to be inserted into a
heat exchanger, the parts, inserted into the
heat pipe reactor core, of the heat pipes are coated with a thermal
ion converter, a hot end of a Stirling
thermoelectric conversion device is connected with the
heat exchanger, a cold end of the Stirling
thermoelectric conversion device is connected with a
water cooling jacket, and finally
waste heat is transmitted into cooling water in the
water cooling jacket. Heat generated by
nuclear fuel fission is conducted to the thermionic converter through the
heat pipe reactor core and then guided into the
heat exchanger through the heat pipes,
temperature difference is formed inside and outside the thermionic converter, and
electric energy is generated through static acting. The heat exchanger uniformly transmits the heat to the hot end of the Stirling
thermoelectric conversion device, the cold end is cooled by the water-cooling jacket, the heat exchanger and the water-cooling jacket form
temperature difference at the two ends of the Stirling thermoelectric conversion device, and
electric energy is generated through dynamic acting. A static thermoelectric conversion mode and a dynamic thermoelectric conversion mode are adopted, the reliability of the power supply is improved, the output power of the power supply is increased, and the power supply is used for multipurpose equipment and systems.
