Abstract
Experiments were conducted to verify whether an oscillating heat pipe (OHP) with a liquid reservoir works as a temperature controllable thermal control device in space. We set an OHP which consisted of a capillary tube turned 20 times between a heating section and two cooling sections and of a liquid reservoir in a thermal vacuum space simulator. It is concluded that temperature of the heating section can be controlled by regulating the reservoir’s temperature even when the heat input and the ambient temperature changes, and that the OHP with the liquid reservoir works as a variable conductance heat pipe.
