Abstract: An isothermalized mirror assembly is a mirror structure that uses a heat pipe to isothermalize heat loads. The isothermalized mirror assembly includes at least one mirror unit and a quantity of thermally-convective fluid. The mirror unit includes a vacuum enclosure, a capillary medium, at least one reflector, and a plurality of cross supports. The vacuum enclosure is the structural base of the isothermalized mirror assembly and is used to retain a vacuum and the thermally-convective fluid. The cross supports are mounted within the vacuum enclosure and increases the structural integrity of the vacuum enclosure. The capillary medium is mounted across the interior of the vacuum enclosure and about each cross support. The capillary medium and the thermally-convective fluid work in conjunction to form a heat pipe within the vacuum enclosure. The reflector is externally mounted to the vacuum enclosure in order to redirect EM radiation.

The collector can be in fluid communication with the heat exchange chamber and configured to collect the liquid film after thermal energy exchange. The collector can be configured to direct at least some of the collected liquid film to the injector for subsequent use.

Abstract: The present invention relates to a portable water dispenser for dispensing cooling water to an overheated compressor of an ACU. The water dispenser includes a splash guard and a core that is installed inside the splash guard. The core includes a magnet that firmly but temporarily attaches the water dispenser to the outer surface with the compressor.
