1. A heat transfer system for a cyclical heat exchange system, the heat transfer system comprising:
- an evaporator comprising;
a heated wall configured to be coupled to a portion of the cyclical heat exchange system;
a primary wick coupled to the heated wall;
a liquid barrier wall, wherein the primary wick is positioned between the heated wall and the liquid barrier wall and wherein the heated wall and the liquid barrier wall are configured to contain a working fluid between adjacent sides of the heated wall and the liquid barrier wall;
a vapor removal channel located at an interface between the primary wick and the heated wall, the vapor removal channel extending to a vapor outlet;
a liquid flow channel located between the liquid barrier wall and the primary wick, the liquid flow channel receiving liquid from a liquid inlet;
a secondary wick between the liquid flow channel and the primary wick; and
a vapor vent channel at an interface between the secondary wick and the primary wick; and
a condenser coupled to the evaporator to form a closed loop that houses a working fluid.

20. A method of transferring heat for a cyclical heat exchange system, the method comprising:
-
vaporizing a liquid in an evaporator comprising; inputting heat energy onto an exterior heat-absorbing surface of a vapor barrier wall; flowing liquid through a liquid flow channel that is defined between a liquid barrier wall and a primary wick; pumping the liquid from the liquid flow channel through the primary wick positioned between the liquid barrier wall and the vapor barrier wall; removing vapor that has vaporized within the primary wick adjacent to the liquid barrier wall away from the primary wick through a vapor vent channel that is defined between the primary wick and a secondary wick located adjacent the liquid barrier wall; and evaporating at least some of the liquid forming a vapor at a vapor removal channel that is defined at an interface between the primary wick and the vapor barrier wall; delivering the vapor from the vapor removal channel to a condenser; condensing the vapor in a condenser forming a liquid; and delivering the liquid from the condenser to the evaporator. - View Dependent Claims (21, 22, 23)
