A heat-exchanger module that conveys a fluid through one or more heat exchangers with little or no pressure drop is presented. The heat-exchanger module comprises a first manifold that smoothly channels the fluid from a fluid source to each of the heat exchangers. The heat-exchanger module further comprises a second manifold that smoothly channels the fluid from the heat exchangers to a fluid sink. The manifolds are dimensioned and arranged to mitigate development of pressure drops in the fluid flow.

Manifolding arrangement for a modular heat-exchange apparatus

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.

Modular heat-exchange apparatus

An embodiment of a device for generating an acoustic signal in a fluid includes an engine operable to repeat a thermodynamic process to vibrate a membrane of the engine to generate an acoustic signal having more than one period. The thermodynamic process includes heating mass inside a chamber of an engine to generate pressure inside the chamber; in response to generating the pressure, moving in a first direction a portion of a membrane of the engine; removing mass from inside the chamber to decrease the pressure inside the chamber; and in response to decreasing the pressure inside the chamber, moving the membrane portion in a second direction. In an embodiment, because the engine repeats the thermodynamic process, the engine can generate and sustain an acoustic signal for a significant amount of time.
