An evaporative heat exchanger system, suitable for rejecting heat in a space environment, has been developed. The system is designed to use water as the evaporant, although other fluids are possible. The major components of the system include an evaporative heat exchanger, water spray nozzles, a back-pressure regulator, a pressurized water supply tank, and appropriate controls. The heat exchanger is a high-performance aircraft-type plate-fin design, with a proprietary hydrophilic coating applied to the evaporant-side flow passages. The hydrophilic coating promotes good contact between the evaporating water and the hot heat transfer surfaces.
