Heat storage system in moon-based extreme environment

Abstract

The invention provides a heat storage system in a moon-based extreme environment. The heat storage system is arranged at a constant zone of subsurface temperature of the moon, the temperature of the constant zone of subsurface temperature is maintained constant, the distance of the constant zone of subsurface temperature from a lunar surface is at least 1 meter, the heat storage system comprises aheat isolation layer, a heat storage layer and a switching assembly, sunlight irradiates the heat isolation layer, the heat isolation layer covers the heat storage layer, the heat conduction coefficient of the heat isolation layer is smaller than that of the heat storage layer, a passage is formed in the heat isolation layer, the heat storage layer communicates with outside by the passage so as to receive heat of the sunlight, and the switching assembly is arranged at the passage and is used for switching the heat storage layer between the state that the heat storage layer is in heat exchangewith the outside and the state that the heat storage layer is not in heat exchange with the outside. By the arrangement, the heat of the heat storage layer is isolated from the outside by the heat isolation layer, heat loss is reduced, the heat storage layer is controlled to absorb / dissipate heat by the switching assembly, the heat storage system is helped to do heat exchange inversing to relatively temperature difference, human activity in the moon extreme environment is facilitated, and deep space exploration by human is facilitated.

Description

technical field [0001] The invention belongs to the field of human activities in lunar-based extreme environments, and in particular relates to a heat storage system for lunar-based extreme environments. Background technique [0002] As the only satellite of the earth, the moon is an outpost for human deep space exploration. The intelligent use of the lunar underground space is an important measure to establish a lunar base and bring the moon into the scope of human activities. Due to the low thermal conductivity of the lunar soil, there is a constant temperature layer below the depth of 1 meter on the lunar surface, and the temperature is maintained at about 250K (-20°C). The Moon's rotation period is the same as its revolution period, which is 29.5 Earth days. The temperature of the lunar surface can reach 127°C during the day and the moon, and the time is 14.74 Earth days, and the moon night is also 14.75 Earth days. The long dark night has brought problems to the energy...
