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.

A gravity independent heat pipe which can be rolled up comprising: two flexible heat conductive sheets bonded together at the edges of their facing surfaces to form an enclosed volume between them, said bonds forming crevices on the perimeter of the enclosed volume which serve as capillary channels; and heat exchange fluid, selected to vaporize and condense in the range of temperatures anticipated for operation of the heat pipe, contained within the enclosed volume.
