Problems solved by technology

When designed according to the traditional method, due to the artificial increase of the maximum heat load, the surface temperature of the radiator is too low when the heat load is low
At the same time, the operating temperature of the working fluid inside the radiator is too low, resulting in increased viscosity of the working fluid, increased operating resistance, increased power consumption of the circulating pump, and even freezing of the working fluid, resulting in the risk of radiator failure

Abstract

The invention relates to a multi-cabin-section spacecraft heat load analysis method. The multi-cabin-section spacecraft heat load analysis method comprises the steps that (a), the outer heat flow condition of a multi-cabin-section spacecraft under various work modes is analyzed; (b), according to the heat output and uncontrollable heat dissipating quantities in all cabin sections under all modes,the controllable heat dissipating quantities generated in all the cabin sections under all the modes is counted up; and (c), the heat dissipating capacity of all the cabin sections is determined, thecontrollable heat dissipating quantities of the all cabin sections are distributed according to the heat dissipating capacity, and heat dissipating components of all the cabin sections are designed. According to the multi-cabin-section spacecraft heat load analysis method, the weight of a heat management system can be effectively controlled, and the risk of invalid freezing of a radiator is avoided.

Description

technical field [0001] The invention relates to the technical field of overall design of spacecraft, in particular to a thermal load analysis method of a multi-cabin spacecraft. Background technique [0002] At present, the development trend of space stations is large-scale multi-chamber, scalability, and multi-mission missions. For example, the foreign Mir space station and the International Space Station are composed of multiple cabin sections. task, designed a variety of working modes. [0003] The thermal management system of the space station is to control the temperature of the air and equipment in the cabin, and generally uses radiators as heat dissipation components. During the orbital operation of the space station, the internal heat sources mainly include equipment heat production and energy system waste heat Q s , occupant metabolic heat production Q r , the external heat source is mainly the external heat flow Q from the sun and the earth w . After the space...
