Abstract: An environmental control system includes a primary heat exchanger operable to transfer heat from an air source to a refrigerant in a generator flow and output an air flow. An ejector is operable to produce an intermediate refrigerant flow based on receiving the generator flow as a motive fluid and drawing a vapor refrigerant flow as a suction fluid. A refrigerant condenser is operable to convert the intermediate refrigerant flow to a liquid refrigerant flow. A pump is operable to provide the refrigerant to the primary heat exchanger from a portion of the liquid refrigerant flow. An expansion device is operable to expand the liquid refrigerant flow prior to entering an evaporator. The evaporator is operable to convert the liquid refrigerant flow to the vapor refrigerant flow and produce a cooled evaporator air flow output based on the air flow.

Abstract: A heat exchanger includes a heat exchanger body. A first set of flow channels is defined in the heat exchanger body extending axially with respect to a first flow axis, wherein the first set of the flow channels forms a first flow circuit. A second set of flow channels is defined in the heat exchanger body extending axially with respect to a second flow axis. The second set of the flow channels forms a second flow circuit that is in fluid isolation from the first flow circuit. Each flow channel is fluidly isolated from the other flow channels. At least some of the flow channels have cross-sections that vary along their respective flow axis.

Abstract: An electronics enclosure has a blower and diffuser received within an enclosure. Electronic components are also received within the enclosure. The blower diffuser is positioned in contact with at least one of the electronic components. A shroud surrounds the blower diffuser and the at least one electronic component, and is spaced from an outer surface of the at least one electronic component. An opening is formed through the shroud, such that air can be driven within the shroud from the blower diffuser, and across at least one electronic component, and then outwardly of the opening. A heat exchanger is positioned in the path of air leaving the opening.
