System configured to control and power a vehicle or vessel
A system configured to power a vehicle or vessel. The system may include an enhanced power control system. The enhanced power control system having a distributed architecture such that power conversion and/or management is provided for individual energy supplies and/or system loads. The distributed architecture of the power control system may enhance the power efficiency of the vehicle or vessel. The distributed architecture of the power control system may enable a plurality of different energy supplies and/or system loads to be incorporated into the power system in a selectable, configurable manner. This may facilitate the addition and/or subtraction of energy supplies and/or system loads from the system to customize the vehicle or vessel for a specific use and/or mission without having to reconfigure the power control system as a whole.
1. A system configured to generate power within an underwater vessel, the system comprising:
a fuel cell;
a chamber that holds a liquid in proximity to the fuel cell such that during operation of the fuel cell waste heat generated by the fuel cell vaporizes the liquid;
a steam generator having one or more turbines that, when driven, cause power to be generated by the steam generator;
a first conduit that carries the vaporized liquid from the chamber to the one or more turbines such that the one or more turbines are driven by the flow of the vaporized liquid;
a cold plate that receives vaporized liquid that has passed through the one or more turbines, the cold plate having a shape that corresponds to the shape of a hull of the vessel and is in direct, conductive thermal communication with the hull such that by virtue of the direct, conductive thermal communication between the cold plate and the hull of the ship the hull of the ship acts as a heat sink for the cold plate; and
a second conduit that receives cooled liquid from the cold plate and guides the cooled liquid back into the chamber.
2. The system of claim 1 , wherein an inner surface of the hull of the vessel is substantially the same shape and size as an outer surface of the cold plate.
3. The system of claim 1 , wherein an inner surface of the hull of the vessel is cylindrical and has a first radius, and wherein an outer surface of the cold plate is cylindrical and has a second radius that is substantially the same as the first radius.
4. The system of claim 1 , further comprising an energy storage unit that is coupled to the fuel cell and the steam generator and one or more system loads associated with the underwater vessel, the energy storage unit being configured to selectively store power generated by the fuel cell and the steam generator, and to selectively power the one or more system loads.
5. The system of claim 4 , further comprising a power management system configured to determine whether power from the fuel cell, the steam generator, and/or the energy storage unit is used to power the one or more system loads at a given time based on one or more parameters of the fuel cell, the steam generator, and the energy storage unit, and based on one or more mission parameters.
6. The system of claim 1 , wherein the vessel is unmanned.
