Abstract

The invention discloses a self-circulating heat management and power generation system for a lunar base. Specifically, liquid saturated organic working media are sent to a cold plate or a directionalsolar collector by a working medium pump and are heated to a saturated or superheated steam state, then a turbine is pushed to rotate so as to drive generating load to generate power, gas working media flow into an ejector after going out of the turbine, gas on the outlet side of a refrigeration evaporator is injected into the ejector, the gas working media and the gas are mixed and diffused in the ejector and then enter a directional space radiator so as to release heat to the space and coagulate in a liquid state, a part of the liquid working media enter the working medium pump again so as to complete the power generating circulation, and the other part of the liquid working media are cooled and depressurized through a throttle valve and return to the refrigeration evaporator again so asto complete the refrigeration cycle. The self-circulating heat management and power generation system can be operated on the moon at daytime or polar day and at night or polar night, own power consumption is satisfied, additional power supply and cold supply are provided for the base, and the power demand of the lunar base is effectively saved.

Description

technical field [0001] The invention relates to a thermal management and power generation system in the aerospace field, in particular to a self-circulating thermal management and power generation system for a lunar base. Background technique [0002] Spacecraft thermal management is proposed along with the enlargement of space vehicles. It is a unified distribution and management of heat in large spacecraft from the perspective of the overall system, and completes the collection, transmission, utilization and dissipation of spacecraft heat. On the one hand, it ensures that its structural components, instruments and equipment are in a suitable temperature range in the space environment, so that they can work normally. On the other hand, ensure that the atmospheric environment in the cabin meets certain temperature conditions for the normal life of astronauts. In addition, the unified allocation and comprehensive utilization of the spacecraft's heat can reduce energy demand...
