Abstract
A heat pipe which can be rolled up for storage and automatically deploys when heat is applied. Two highly flexible parallel sheets are bonded together at their edges, thus permitting compact rolled storage. The inside portions of the joined edges form creases which act as capillary channels to move the heat exchange liquid from the condenser to the evaporator. A further embodiment involves multiple longitudinal cells which yield many more capillary channels and increases the structural strength of the deployed heat pipe, while maintaining the large surface area for heat transfer.
