Abstract
A heat pipe which maintains a controlled temperature gradient over its length. An annular heat pipe is constructed to have a core area which is a working furnace and to have the heat input at one end and a heat sink at the other end of the annular structure. The core is surrounded by an annular vapor space with a restricted cross section. The reduced vapor space creates a temperature gradient over the length of the furnace, and this gradient is variable and controllable depending upon the quantity of heat being transferred from the heat source to the heat sink.
