1. A heat exchanger for cooling a fluid comprising:
a plurality of phase change material modules mounted for rotation about a central axis to form a porous structure having a porosity of from 94% to 98%, each said phase change material module including a plurality of hollow structures and a phase change material housed within the hollow structures;
a first fluid inlet positioned to direct the fluid through the porous structure for contact between the first fluid and an outer surface of the hollow structures;
a first fluid outlet for removing the first fluid from the heat exchanger and located to receive the first fluid after contact with the hollow structures;
a second fluid inlet positioned to direct a second fluid through the porous structure for contact between the second fluid and the outer surface of the hollow structures; and
a second fluid outlet for removing the second fluid from the heat exchanger and located to receive the second fluid after contact with the hollow structures;
wherein rotation of the plurality of phase change material modules repeatedly circulates the porous structure of the modules into alignment with the first fluid inlet and the second fluid inlet, and the phase change material is selected to undergo a phase change as a result of heat exchange with each of the first and second fluids, and the outer surfaces of the hollow structures are formed from a hydrophobic material.
