Abstract

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.

Description

technical field [0001] The invention relates to the technical field of reactor design, in particular to a multi-purpose dual-mode nuclear reactor power supply Background technique [0002] With the development of space exploration, aerospace equipment systems have put forward a major demand for space nuclear reactor power. Reliable and safe space nuclear reactor power is the main direction of future space exploration. [0003] At present, the power supply of space nuclear reactors mostly uses static or dynamic conversion design. The static conversion efficiency is low and the mass specific power is high, which is difficult to meet the needs of future aerospace. Operation is prone to failure. Contents of the invention [0004] In order to overcome the above-mentioned problems in the prior art, the present invention proposes a multi-purpose dual-mode nuclear reactor power supply, which can be used by various equipment and systems. [0005] In order to achieve the above obj...
