Flexible recyclable material-based space consumption type heat dissipation working medium recycling method

Abstract

The invention provides a flexible recyclable material-based space consumption type heat dissipation working medium recycling method. The method specifically comprises the steps of (1) estimating mass of a required liquid working medium according to a peak heat load, working time, an adopted working medium type and a working temperature of a spacecraft heat control system; (2) according to a demand of a consumption type heat dissipation apparatus on a working backpressure, setting a highest working backpressure; based on the estimation of the mass of the working medium and the highest working backpressure, estimating the volume of a gas working medium generated by evaporation in a working process of equipment; (3) selecting a flexible material to design a space consumption type heat dissipation working medium recycling apparatus, and enabling the internal volume of the recycling apparatus in a natural extension state to be greater than or equal to the volume of the gas working medium; and (4) recycling a space consumption working medium by combined use of the working medium recycling apparatus and the space consumption type heat dissipation apparatus. Necessary technical guarantee is provided for application of a space consumption type heat dissipation method to a long-term space navigation task.

Description

technical field [0001] The invention belongs to the technical field of spacecraft thermal control, and in particular relates to a method for recovering space-consuming heat-dissipating working fluid based on flexible and recyclable materials. technical background [0002] The heat dissipation of the spacecraft in the space environment will be realized through radiation heat dissipation or exhausting the consumption medium in a vacuum environment. Radiation heat dissipation is an ideal space heat dissipation measure for long-term space missions, and it is the most commonly used heat dissipation method for space vehicles. The radiation cooling capacity of the spacecraft is related to the temperature of the cooling surface, the size of the cooling area, the surface emissivity of the cooling surface, and the thermal environment of the cooling surface. In order to ensure a certain amount of heat dissipation, the spacecraft must provide a sufficient area of ​​heat dissipation sur...

[0005] In view of this, the present invention proposes a method for recovering space-consuming heat-dissipating working fluid based on flexible and recyclable materials. The method uses physical methods to collect and liquefy the gaseous working medium discharged from the space-consuming heat-dissipating device for recycling. Utilization can solve the problem that the current space-consuming heat dissipation working medium cannot be recycled and reused, and restricts the application of consumable heat dissipation in long-term space missions.
