    • According to one embodiment, an apparatus includes a fluid coolant and structure which reduces a pressure of the fluid coolant through a subambient pressure at which the coolant has a cooling temperature less than a temperature of the heat-generating structure. The apparatus also includes structure that directs a flow of the fluid coolant in the form of a liquid at a subambient pressure in a manner causing the liquid coolant to be brought into thermal communication with the heat-generating structure. The heat from the heat-generating structure causes the liquid coolant to boil and vaporize so that the coolant absorbs heat from the heat-generating structure as the coolant changes state. The structure is configured to circulate the fluid coolant through a flow loop while maintaining the pressure of the fluid coolant within a range having an upper bound less than ambient pressure. The apparatus also includes a first heat exchanger for exchanging heat between the fluid coolant flowing through the loop and a second coolant in an intermediary loop so as to condense the fluid coolant flowing through the loop to a liquid. The apparatus also includes a second heat exchanger for exchanging heat between the second coolant in the intermediary cooling loop and a body of water on which the ship is disposed.

    • A heat exchanger extracts heat from a two-phase fluid coolant so that the coolant changes from a vapor state to a liquid state. Two valves have respective inlets which communicate with the coolant in the heat exchanger, and which are physically spaced from each other. Valve control structure responds to the presence of liquid at the inlet to either valve by opening that valve, so that the liquid coolant flows through the valve to a discharge section. A different feature involves a housing with a heat exchanger therein, the heat exchanger having a plurality of coolant conduits that are axially spaced. A flow of air travels axially within the housing, then flows transversely past the conduits to the other side thereof, and then resumes flowing axially on the other side of the conduits.
    • 热交换器从两相流体冷却剂中提取热量,使得冷却剂从蒸汽状态变为液态。 两个阀具有与热交换器中的冷却剂连通并且彼此物理间隔开的各自的入口。 阀控制结构通过打开该阀来响应在两个阀的入口处的液体的存在,使得液体冷却剂通过阀流到排出部分。 不同的特征涉及其中具有热交换器的壳体,热交换器具有轴向间隔开的多个冷却剂导管。 空气流在壳体内轴向移动,然后横向流过管道至其另一侧,然后在导管的另一侧沿轴向流动。

    • According to one embodiment of the invention, a cooling system for heat-generating structures comprises a plurality of heat exchangers, a structure which directs flow of the fluid coolant substantially in the form of a liquid to each of the plurality of heat exchangers, and a structure which reduces a pressure of the fluid coolant to a pressure at which the fluid coolant has a boiling temperature less than a temperature of the heat-generating structures. Each of the plurality of heat exchangers is in thermal communication with at least one of the heat-generating structures and has an inlet and an outlet. Thermal energy from the heat-generating structure causes the fluid coolant substantially in the form of a liquid to boil and vaporize in each of the plurality of heat exchangers so that the fluid coolant absorbs thermal energy from the heat-generating structure as the fluid coolant changes state.
