Multipurpose small nuclear reactor power supply

Abstract

The invention discloses a multipurpose small nuclear reactor power supply comprising a reactor core, a heat pipe, a shielding body and a thermoelectric power generation device. One end of the heat pipe is inserted into the reactor core and the other end is inserted into the thermoelectric power generation device. The shielding body is arranged between the reactor core and the thermoelectric powergeneration device. The heat pipe penetrates through the shielding body and the shielding body protects the thermoelectric power generation device from serious radiation damage of the reactor core. Thethermoelectric power generation device comprises thermocouple conversion elements which are arranged at intervals and a cooling passage. The heat pipe is inserted into the thermoelectric power generation device and located on the outer side the thermocouple conversion elements on the two sides of the cooling passage so that the heat pipe is enabled to heat one side of the thermocouple conversionelements in the thermoelectric power generation device and the water in the cooling passage is enabled to cool the other side of the thermocouple conversion elements. The thermocouple conversion elements generates an electric potential by utilizing the temperature difference between the two ends to convert heat energy into electric energy to be used for the multipurpose equipment and system.

Description

technical field [0001] The invention relates to the technical field of reactor design, in particular to a multipurpose small nuclear reactor power supply. Background technique [0002] With the advancement of science and technology, the development of special equipment has put forward a major demand for high-power, long-life power supply systems. [0003] Currently, the power supply systems for small, mobile-deployed special equipment are mostly chemical power sources, such as batteries, fuel cells, heat engines, or solar energy. Long-life power sources also include isotope power sources, which are mainly used in spacecraft and the like. In the above-mentioned traditional power system, the chemical energy power supply has low output power and insufficient endurance, which is difficult to meet the long-term work needs of large special equipment; the solar power supply is large in size and size, and is not easy to deploy; although the isotope power supply has a lifespan of se...

AI Technical Summary

Problems solved by technology

In the above-mentioned traditional power system, the chemical energy power supply has low output power and insufficient endurance, which is difficult to meet the long-term work needs of large special equipment; the solar power supply is large in size and size, and is not easy to deploy; although the isotope power supply has a lifespan of several years above, but the output power is low, it is difficult to meet the demand

In addition, the traditional power supply environment adaptability is not strong, and it is difficult to adapt to harsh working environments, such as high and low temperature, vacuum, radiation, shock and vibration, etc.
