| Outline of Final Research Achievements |
In anticipation of the sophistication and smartification of space missions, we proposed the concept of a thermo-fluid control network with a multi-evaporator type loop heat pipe which satisfies high heat flux, small size and light weight, and large thermal fluctuation response. We succeeded in constructing a high-performance multi-evaporator type loop heat pipe based on the fundamental academic findings of high heat flux on the evaporator and understanding of the elementary process of the condenser, and demonstrating high heat transport characteristics and autonomous heat control function in a simulated space environment.

| Academic Significance and Societal Importance of the Research Achievements |
宇宙機ミッションの高度化，小型化に伴い熱制御要求が厳しくなりつつあり，従来のヒータとラジエータによる制御だけでは熱設計が成立しにくくなっていた。そのような状況に対して，本提案では自律機能を有する無電力熱輸送技術ならびにその知能的制御特性を実証できており，宇宙機熱制御の高度化に資する成果である。また本成果は宇宙環境のみならず民生機器の熱マネージメントにも応用できるため極めて意義が高い。
