Abstract

The invention relates to a nuclear power supply device, comprising a graphite substrate, a plurality of fuel rods, a plurality of heat pipes and a thermoelectric converter, the graphite substrate is provided with a plurality of first through holes and a plurality of second through holes, wherein the first through holes The channels are filled with liquid coolant, and each fuel rod is placed in each first through hole for generating heat energy and transferring the heat energy to the graphite substrate through the liquid coolant, and then the graphite substrate is transferred to the graphite substrate through the heat pipe built in the second through hole. The thermal energy is transferred to the thermoelectric converter for thermoelectric conversion, in which the liquid coolant acts as a buffer between the fuel rod and the graphite matrix, and plays a transition role in the heat energy transferred from the fuel rod to the graphite matrix, thus avoiding the temperature gradient And the impact of fuel rod swelling on the graphite matrix improves the safety of the nuclear reaction process.

Description

technical field [0001] The invention relates to the technical field of nuclear reaction power generation, in particular to a nuclear power supply device. Background technique [0002] Typical offshore and submarine observation equipment, such as offshore buoys, observation buoys, and submarine networks, have a strong demand for long-term stable supply of energy. Energy supply issues have become a bottleneck that restricts further understanding, exploration, and perception of the deep sea. For example, the submarine observation network is limited by the bottleneck problem that cable power supply is difficult to lay in a large area to the deep sea. It usually needs to be equipped with low-power equipment, which greatly limits the signal acquisition and transmission capabilities; huge influence. [0003] Compared with fossil energy and renewable energy, nuclear energy has the characteristics of high energy density, good stability, and low fuel supply requirements, and is an id...
