Lunar soil source thermoelectric generator

Abstract

The invention discloses a lunar soil source thermoelectric generator, which comprises a thermoelectric generation module and a power storage module, wherein the thermoelectric generation module is connected with the power storage module; the lunar soil source thermoelectric generator is characterized in that the thermoelectric generation module comprises a radiant cooling plate, a thermoelectric generation sheet and a self-circulating heat pipe; the radiant cooling plate for cooling is attached to a cold end surface of the thermoelectric generation sheet; a hot end surface of the thermoelectric generation sheet is connected with the self-circulating heat pipe; the self-circulating heat pipe is buried into lunar soil, absorbs heat of the lunar soil and transmits the heat to the hot end surface, in contact with the self-circulating heat pipe, of the thermoelectric generation sheet, so that the hot end surface of the thermoelectric generation sheet is kept at high temperature; and furthermore, due to the radiant heat transfer effect of the radiant cooling plate and the moon space, the cold end surface, attached to the radiant cooling plate, of the thermoelectric generation sheet is kept at low temperature, and a stable temperature difference is finally formed between the hot end surface and the cold end surface of the thermoelectric generation sheet and is stored into a storage battery through thermoelectric generation, thereby ensuring efficient lunar exploration activities at night.

Description

technical field [0001] The invention relates to a temperature difference power generation device, in particular to a lunar temperature difference power generation device, in particular to a lunar soil source temperature difference power generation device. Background technique [0002] The moon has a variety of unique resources that can be developed and utilized by humans. The unique minerals and energy on the moon are important supplements and reserves for the earth's resources. Returning to the moon, developing lunar resources, and establishing lunar bases have become inevitable for human spaceflight activities. Trends and competitive hotspots. For this reason, in 2004, China officially launched the lunar exploration project and named it "Chang'e Project". Regardless of the stage of the Chang'e project, whether energy can be supplied efficiently and in a timely manner will be the key to the success or failure of the Chang'e project. [0003] At present, the energy require...

AI Technical Summary

Problems solved by technology

[0003] At present, the energy required for the deep space exploration process mainly depends on solar power supply. However, in a month, the moon’s day and night time are as long as 14.75 days. Undoubtedly, it will greatly affect the efficiency of lunar exploration. Therefore, the development of other reliable and durable energy sources other than solar energy is of vital significance to the lunar exploration project
