Though these new forms of heat pipes are able to transfer significant heat flows and can increase heat transport length, they remain very sensitive to spatial orientation relative to gravity. To extend the functional possibilities of two-phase systems to applications involving otherwise inoperable slopes in gravity, the advantages provided by the spatial separation of the transportation line and the usage of non-capillary arteries are combined in a loop scheme.
These new heat pipe designs can transfer significant amounts of heat but are sensitive to their orientation relative to gravity. To expand their use in applications where slopes are problematic, the advantages of separating the heat transport line and using non-capillary arteries are combined into a loop scheme.
