Abstract:
Exchanger devices include a plurality of fixed exchange ducts and a rotating valve assembly for directing flow to and from the plurality of exchange ducts. Methods of exchanging pressure between fluid streams may include directing fluids through an exchange device and pressurizing a fluid in the plurality of exchange ducts of the exchanger device.
Abstract:
A heat exchange tube, a heat exchanger using such a tube and a method of making such a tube. Additive manufacturing is used to form at least a portion of the tube. Augmented heat exchange features, such as external and internal lattice structure may be built up along with the remainder of the tube to form an enhanced heat exchange region with intermittent, repeating shapes. Such shapes maximize heat-dissipating surface area of the tube while reducing or eliminating large external dimensions associated with traditional tube manufacture.
