A heat pipe has a sealed envelope. A primary wick extends along an inside surface of the envelope. A working fluid is contained within the envelope. The fluid is capable of undergoing a liquid/vapor phase change. An evaporator section is defined within the envelope for vaporizing the fluid. The evaporator section has at least one high heat flux area that is capable of being thermally coupled to an external heat source to be cooled by the heat pipe. A secondary wick is formed of mesh screens or sintered metal powders. The secondary wick is connected to the primary wick in the high heat flux area and connected to the primary wick at a location approximately opposite the high heat flux area, for transporting subcooled liquid to the high heat flux area. A condenser section is defined within the envelope for condensing the vaporized fluid.
