| Abstract: |
| With the rapid advancement of aerospace technology and the intelligent upgrading of space-based information systems，the sharply increasing power consumption and heat flux density have become critical challenges constraining the performance and reliability of space-based computing systems.To assess the state of the art and future research directions in thermal management for space-based high-power payloads，the extreme thermal management challenges faced by such payloads and their core heat dissipation requirements are systematically analyzed.On this basis，the advantages and limitations of existing thermal management technologies and thermal materials for spacecraft electronic devices are reviewed.Finally，an in-depth analysis of the current technical challenges is provided，along with prospects for future directions for spacecraft high-heat-flux thermal management technologies，in hope of providing reference for their engineering application and subsequent development. |
