Abstract: An absorption chiller system includes a generator section, a condenser section, an evaporator section and an absorber section all in fluid communication with each other and which operate to circulate a refrigerant therethrough. The evaporator section includes a transport membrane heat exchanger. The transport membrane heat exchanger includes a first and a second flow path. The first flow path is operable to flow the refrigerant therethrough under a vacuum pressure that is low enough to vaporize the refrigerant within the first flow path. The second flow path is operable to pass a fluid having water therethrough. Both water and heat are transferred from the fluid in the second flow path to the refrigerant in the first flow path through a membrane-based material of the transport membrane heat exchanger, such that the fluid passing through the second flow path has at least a portion of its water removed and is cooled.

Abstract: A piston with a cooling gallery containing an open cell radiator is provided. The radiator has a large thermally conductive surface area that acts as a heat-sink to remove heat from the piston. Heat from the piston is transmitted from the radiator to cooling oil that enters the cooling gallery via an oil inlet formed in a floor of the cooling gallery and exits the cooling gallery via an oil outlet. The piston comprises a piston body including an upper part presenting an upper combustion surface and an undercrown surface. A ring belt depends from the upper combustion surface, and the cooling gallery extends around the piston body beneath the undercrown surface radially inwardly of the ring belt. The radiator includes a plurality of fins extending annularly around the cooling gallery. The fins of the radiator are spaced from one another by gaps extending annularly around the cooling gallery.

Abstract: Heat transfer in coolant circuits, as in an internal combustion engine for example, can be beneficially enhanced by maintaining the coolant in a nucleate boiling state, but undesirable transitions to a film boiling state are then possible. The disclosed coolant circuit has selected surface(s) that have a tendency to experience high heat flux in comparison to adjacent surfaces in the coolant circuit. These surfaces are provided with a surface configuration, such as a matrix of nucleation cavities, which has a tendency to inhibit a change in boiling state. The surface configuration can be provided on the parent coolant circuit surface or on a surface of an insert positioned in the coolant circuit. Thus, transitions to film boiling can be effectively avoided at locations in the coolant circuit that are susceptible to such transitions.
