A nested structure of nuclear fuel rods and heat-pressure conversion heat transfer devices

Abstract

The invention discloses a nested structure of a nuclear fuel rod and a heat transfer device for thermal pressure conversion. The linear section of the conversion heat transfer device, the heat insulation section of the first heat-pressure conversion heat transfer device, the heat insulation section of the second heat-pressure conversion heat transfer device, and the cooling section of the heat-pressure conversion heat transfer device. The heat-to-pressure conversion heat transfer device is a closed cycle loop, which ensures that the heat transfer medium at the heating end expands when heated, forming a pressure wave, which squeezes the heat transfer medium, drives the liquid working medium to circulate, and flows to the cooling end to dissipate heat Then flow to the heating end, and so on, so that the heat-pressure conversion effect continues to be maintained.

Description

technical field [0001] The invention belongs to the technical field of nuclear power energy, and in particular relates to a nested integrated structure of nuclear fuel rods and heat-pressure conversion heat transfer devices. Background technique [0002] With the development and implementation of deep space exploration programs of various countries in the world, the flight distance of spacecraft is getting farther and farther, and space power energy has become an important constraint factor for space activities. In space exploration, especially deep space exploration, spacecraft need high-power, long-life, and highly reliable space power supplies. The power and working life that solar energy and chemical energy can provide are limited. Compared with other energy sources, nuclear energy has the advantages of high power density, high specific power, long life, stable working performance, and strong environmental adaptability, making it an ideal energy source for space explora...

Problems solved by technology

However, due to the internal mechanism requirements of phase change and reflux, traditional heat pipes are difficult to make into more complex systems. They are greatly affected by gravity and acceleration and cannot operate under the condition of no gravity in space. The use of space nuclear reactors cannot achieve the same effect as on the ground.
