Study on Parameters Influencing Heat Dissipation Performance of Body-Mounted Fluid Tube Radiators

Abstract

Body-mounted fluid tube radiators (BMFTR) serve as integral components in manned spacecraft and are crucial for effective heat dissipation. This study presents a comprehensive simulation analysis model for BMFTR, accounting for the errors in simulation accuracy resulting from assumptions of constant parameters. Through simulation analysis, this research investigates the multifaceted influences of parameters—such as spacecraft orbital [Formula: see text] angle, solar absorptivity of coating, fluid temperature, and fluid flow rate—on the heat dissipation performance of BMFTR. Quantitative assessments uncover distinct impacts of these parameters on radiator performance. The findings offer insights essential for optimizing the operating conditions of BMFTR, providing guidance for enhanced operational management during missions in orbit. This work contributes to advancing radiator technology and facilitating efficient heat management in space exploration.
