Nested structure of nuclear fuel rod and heat-pressure conversion heat transfer device

Abstract

The invention discloses a nested structure of a nuclear fuel rod and a heat-pressure conversion heat transfer device. The heat-pressure conversion heat transfer device is a pipeline forming a closed circulation loop, and comprises a heat-pressure conversion heat transfer device spiral arrangement section, a heat-pressure conversion heat transfer device linear section, a first heat-pressure conversion heat transfer device heat insulation section, a second heat-pressure conversion heat transfer device heat insulation section and a heat-pressure conversion heat transfer device cooling section. The heat-pressure conversion heat transfer device is a closed circulation loop, it is guaranteed that a heat transfer working medium at the heating end is heated to expand to form pressure waves, the pressure waves extrude the heat transfer working medium to drive a liquid working medium to circularly work, flow to the cooling end for heat dissipation and then flow to the heating end, and the heat-pressure conversion effect is continuously maintained through the circulation.

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 a nuclear fuel rod and a thermal pressure conversion heat transfer device. Background technique [0002] With the development and implementation of deep space exploration programs in various countries around the world, spacecraft fly farther and farther, and space power energy has become an important constraint on space activities. In space exploration, especially in deep space exploration, spacecraft require 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, and has become an ideal energy source for space exploration.

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.
