LOX HEAT SINK SYSTEM FOR UNDERWATER THERMAL PROPULSION SYSTEM

摘要

A closed thermal power system ideally suited for submersibles includes an internal combustion engine or turbine connected to feed its exhaust gases to a water cooled condenser for condensing and purging water from the system. Next, a cryogenic source of liquid oxygen receives the gases and carbon dioxide is sublimated to the solid state and stored at low pressure. As carbon dioxide is cooled, oxygen is boiled off and fed to the engine where it is mixed with fuel and recycled portions of the exhaust gases. Because the system is operated at near atmospheric pressures, heavy duty pressure lines and fittings are unnecessary. When the system is operated as an open system in the atmosphere, more liquid oxygen is generated to extend the system's operational range.
