Abstract
A heat transport device includes a heat pipe having a capillary container having a wick and a working fluid arranged therein. A first heat source is coupled to a first end of the capillary container to define an evaporator section and a cold sink is coupled to a second end of the capillary container to define a condenser section. A capillary pump includes an evaporator and a reservoir configured to store an additional supply of working fluid. A second heat source coupled to the evaporator is configured to vaporize the working fluid arranged therein. A fluid loop couples the capillary pump to the heat pipe. Upon detection of a predetermined condition indicative that a majority of the working fluid within the heat pipe is frozen, the capillary pump is configured to supply vaporized working fluid to the heat pipe.
