Abstract
A heat pipe with an improved wick design has an unheated section of greater wick wall thickness next to the evaporator section of the heat pipe and on the opposite side of the evaporator section from the condenser section. The greater wick wall thickness acts as a reservoir of liquid heat pipe working fluid to prevent dry out of the wick during pulsed high thermal energy transfer conditions and to eliminate the need to enforce quasisteady state heat input requirements during start-up operation.
