摘要： A heat exchanger for thermally coupling a first fluid and second fluid is disclosed. The heat exchanger comprises plates comprising cores of thermally conductive graphite foam. A plurality of conduits for conveying the first fluid is formed in each core. Each plate further comprises thermally conductive barriers that sandwich the core, wherein the barriers are substantially impervious to r the first fluid and second fluid. Plates are stacked in a frame such that the frame and plates collectively define a plurality of channels for conveying the second fluid. Heat is exchanged between the primary fluid and the secondary fluid through the graphite-foam cores and barriers.Heat exchangers in accordance with the present invention can be lighter, have improved ratio of heat transfer surface density to heat exchanger volume, be lower cost, and/or be smaller for a given heat transfer capability than prior-art heat exchangers.

摘要： A heat exchanger module for thermally coupling a first fluid and second fluid is disclosed. The heat exchanger module comprises a plurality of heat exchangers, each of which is fluidically coupled to a common seawater inlet and a common seawater outlet. The heat exchanger module is dimensioned and arranged for integrating with an OTEC system located on an offshore platform that is deployed in a body of water. The heat exchanger module physically and fluidically couples with ports included in pontoons attached to the offshore platform. The ports are individually controllable so that the module can be added or removed from the OTEC system without interrupting operation of other heat exchanger modules integrated with the OTEC system.

摘要： A hybrid plate-fin heat exchanger for exchanging heat between a first fluid and a second fluid is disclosed. The hybrid plate-fin heat exchanger comprises a plurality of plates, each of which comprises channels for conveying the first fluid. Fins are brazed onto each plate, wherein the fins define a plurality of flow channels for the second fluid. The plates are joined to one another via friction-stir welding in such a way that the brazed regions are fluidically isolated from the first fluid during operation. As a result, the heat exchanger is suitable for use in applications that use a first fluid, such as seawater or geothermal fluid, which is corrosive for the brazed regions.

摘要： A method for extracting fuel gases from an underwater plume emitted from an underwater hydrothermal vent includes the step of collecting via an underwater fluid collector an underwater plume emitted from the hydrothermal vent. The underwater plume includes methane and hydrogen. The method further includes a step of directing a first fluid containing the underwater plume into a first inlet of a first underwater heat exchanger and a second fluid into a second inlet of the first underwater heat exchanger. The second fluid at the second inlet is at a temperature sufficiently lower than the temperature of the first fluid to transfer sufficient heat therebetween to form methane hydrate and hydrogen-methane hydrate in the first fluid. The method further includes the step of conveying the methane hydrate and hydrogen-methane hydrate to the surface of the water body via a duct connected to a first outlet of the first heat exchanger.

摘要： A modular heat exchanger that can be submerged to great depths and then easily recovered in order to reduce the costs and disadvantages of the prior art. Because the heat exchanger is submergible and recoverable, it can be more easily maintained. This ease of maintenance allows the heat exchangers to be deployed at greater depths. This, in turn, allows for greater differences in temperatures, greater efficiency for the heat engine, and a more effective ocean thermal energy conversion system.
