Space-consuming heat dissipation refrigerant recovery method based on flexible and recyclable materials

Abstract

The invention provides a method for recovering space-consuming heat-dissipating working fluid based on flexible and recyclable materials. The specific process is: (1) According to the peak heat load, working time, working medium type and working temperature of the spacecraft thermal control system Estimate the quality of the required liquid working fluid; (2) Set the maximum working back pressure according to the demand of the consumable cooling device for working back pressure; Estimate the volume of the generated gaseous working medium; (3) select a flexible material to design a space-consuming heat dissipation working medium recovery device, so that the internal volume of the recovery device in a naturally extended state is greater than or equal to the volume of the gaseous working medium; (4) The working medium recovery device is used in conjunction with the space-consuming heat sink to realize the recovery and reuse of the space-consuming working medium. The invention provides indispensable technical support for the application of the space-consuming heat dissipation method in long-term space missions.

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. Background technique [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.
