An apparatus having a heat transfer surface for transfer of heat from the apparatus to a liquid. The heat transfer surface includes at least two different materials and at least two of said materials have different thermal conductivities. A method of boiling at least one liquid which provides increased heat transfer from a heat transfer surface of an apparatus to a liquid comprising a step of boiling said liquid in contact with the apparatus, is also disclosed. Also described is a method of tuning a heat transfer surface by forming the heat transfer surface using at least two different materials having different thermal conductivities arranged in a predetermined spatial relationship including a spacing between the portions of one said material that is from about 0.1λto about 5λ, wherein λis a capillary length of a bubble of a predetermined liquid to be boiled using said heat transfer surface.

Phase change material modules for use in a heat exchanger are described. The phase change material module comprises two or more set of a plurality of substantially aligned hollow structures arranged to form a porous structure. A phase change material capable of undergoing a phase change as a result of heat exchange between it and a fluid is housed within the hollow tubes. Also described is a phase change material module with hollow tubes having a cross-sectional area through the phase change material selected from elliptical, rectangular, stadium-shaped, teardrop-shaped, airfoil-shaped, rounded rectangle and ovoid. A heat exchanger comprising a plurality of the phase change material modules, a first fluid inlet and outlet, and a second fluid inlet and outlet, wherein the phase change material modules are repeated circulated from alignment with the first fluid inlet and the second fluid inlet is also described.

Cooling systems and methods for cooling in a power plant using a phase change material. In one embodiment, a phase change material container includes at least one phase change material which may be in the form of a slurry; and at least one conduit for transporting the fluid through the phase change material when located in the phase change material container. The system may also comprise an air flow chamber; and a phase change material flow system including a pump for pumping phase change material from an outlet of phase change material container, to at least one phase change material spray nozzle. The phase change material flow system is configured to ensure that solidified phase change material is returned to the phase change material container.
