A modular distillation apparatus including at least one heat exchanger that preheats contaminated liquids; a heater that heats the contaminated liquid from the heat exchanger; an evaporator condenser adapted o boil the contaminated liquid coming out of the heater to produce water vapor and contaminant concentrate, and condenser the water vapor into distilled water; a vacuum chamber capable of operating at below atmospheric pressure, the vacuum chamber housing the evaporator condenser and including at least one partition to separate the distilled water from the contaminate concentrate; a vapor compressor operably associated with the vacuum chamber to receive water vapor from the evaporator condenser in the vacuum chamber and pump the water vapor at pressure back through the evaporator condenser, wherein the heat exchanger recovers sensible heat from outgoing condensed distilled water and contaminant concentrate recycled from the vacuum chamber.

Embodiments of the invention provide systems and methods for heat transfer systems at temperatures in the range of 20 C to 800 C. The systems consist of heat pipes configured such that they fit inside conventional heat exchangers, and more effectively transfer or recover heat from hot fluids, and that operate without user intervention over long periods of time.

A heat exchange device comprising phase change material-impregnated heat conductive foam disposed between fluid stream channels in a heat exchanger element.

A discontinuously operating desublimator for the recovery of products from gas mixtures is disclosed having a housing including an inner cooling line and a housing wall, inwardly directed lamellae arranged on an inside of the housing wall which can be cooled for the desublimation of the product by a cooling medium conducted through ducts on the housing wall. The housing is cylindrical and enables the product to be melted down by a change of pressure.

Apparatus for desubliming, condensing or evaporating a fluid. The apparatus includes a chamber and at least one tubular member for desubliming, condensing or evaporating the fluid on the outer surface of the at least one tubular member. The chamber is provided with at least one inlet for the fluid and at least one outlet for the condensate and/or evaporate, and at least one supply and at least one discharge for a cooling and/or heating fluid. The tubular member includes an outer member and an inner member enclosed within the outer member. The inner member is in communication with the supply at a first end. The outer member is in communication with the discharge at a first end. The outer member is closed at a second end. The inner member is open and mouths into the outer member at a second end.

Fins have a region not provided with a heat transfer promoting portion and a region other than the region provided with the heat transfer promoting portion, and the region not provided with the heat transfer promoting portion is set to a region between a lower end portion of a heat transfer tube and an upper end portion of a heat transfer tube.

The heat exchanger includes at least one tube array in which refrigerant flows, the tube array includes a plurality of tubes each having a channel formed therein, and connection members coupled to opposite ends of the tubes so as to interconnect the tubes, and the tubes are injection molded integrally with the connection members.

An end cover structure and a water chiller. The end cover structure includes: an end cover body; a water inlet pipe, provided on the end cover body; a water outlet pipe, provided on the end cover body, the water outlet pipe and the water inlet pipe being provided independent of each other; a bypass pipeline in which two cavities are formed, one of the two cavities being communicated with the water inlet pipe, and the other being communicated with the water outlet pipe; and an adjusting member, movably provided in the bypass pipeline. The adjusting member is movable to adjust the communication between the two cavities.

Embodiments of the invention provide systems and methods for heat transfer systems at temperatures in the range of 20 C to 800 C. The systems consist of heat pipes configured such that they fit inside conventional heat exchangers, and more effectively transfer or recover heat from hot fluids, and that operate without user intervention over long periods of time.

A laser weapon system is described. Particularly, embodiments describe subsystems of a laser weapon system including those necessary for laser generation, operational control, optical emission, and heat dissipation configured to provide a lightweight unit of reduced dimensions.
