A heat pipe has the usual central wick for transporting a liquid, such as a cryogenic liquid, from end to end. A secondary wick transports liquid radially between the central wick and the wall of the heat pipe. This secondary wick is formed with lobes for contacting the heat pipe walls. In this manner, much of the wall surface is free of any contact with the wick, thereby providing improved heat transfer characteristics.
