Abstract
A closed two phase liquid-vapor heat transfer device is provided which is independent of orientation and requires no wick. A micro helix containment vessel contains liquid to form a coolant vapor phase. Heat input at the evaporator section results in evaporation of the liquid at the liquid-vapor interface. The vapor flows through the bellow and condenses on the opposite end where heat is rejected and liquid is replenished to the evaporator section by flow through capillary passages of helical form in the corrugations of the bellows.
