Abstract: Loop Heat Pump (LHP) has great application potentiality in spacecraft thermal control field due to its high efficiency and long distance in heat transfer,good performance in thermal control and flexibility and convenience in installation.Pressure drop of working fluid in LHP is calculated and analyzed.The maximum heat transfer capacity based on LHP capillary structure is forecasted.And combined with experimental research,influence of the capillary structure on LHP characteristics is discussed.
