Abstract

The invention discloses a thermoelectric generating unit, a molten salt reactor and an operation method and application of the molten salt reactor. The thermoelectric generating unit is used for condensing ends of heat pipes, and comprises hot end sleeves and cold end sleeves; the hot end sleeves are used for sleeving the condensing ends of the heat pipes, the outer side walls of the hot end sleeves are flat, and the bottom of each hot end sleeve is connected with the bottom of the adjacent hot end sleeve to form a hot end sleeve body; the cold end sleeves provided with inner cavities and matched with the hot end sleeves sleeve each hot end sleeve, the bottom of each cold end sleeve communicates with the bottom of the adjacent cold end sleeve to form a cold end sleeve body with an inner cavity, and cooling medium inlets and cooling medium outlets are formed in the cold end sleeve bodies; thermoelectric generating plates are posted between the outer side walls of the hot end sleeve bodies and the inner side walls of the cold end sleeve bodies; and the outer side walls of the hot end sleeve bodies and the inner side walls of the cold end sleeve bodies are fitted at positions where the thermoelectric generating plates are not posted The thermoelectric generating unit can improve the heat transfer capacity.

Description

technical field [0001] The invention relates to a thermoelectric power generation unit, a molten salt reactor and its operation method and application. Background technique [0002] With the development of science and technology, people are accelerating the pace of exploration of special environments such as outer space and deep sea. Traditional energy systems are not adaptable to harsh working environments such as high and low temperature, vacuum, radiation, shock and vibration due to their large size, poor battery life, etc. Strong and other reasons, it is difficult to meet the long-term work needs of large-scale special equipment. The technical development of nuclear energy power sources that are not affected by the environment, have a long life, and are safe and reliable have been paid more and more attention. [0003] Reactors suitable for special environments currently considered in the world include gas-cooled reactors and liquid-cooled reactors. Gas-cooled reactors ...
