Abstract:
A miniaturized waste heat engine configured to recuperate waste energy from a heat source and convert said waste energy into useable energy, said engine comprising:at least one heat source, at least one thermal seal which separates cooled parts of said heat source from the hottest parts of said heat source, at least one liquid-to-liquid heat converter separating a cooling fluid of said cooled parts of said heat source from a low vapor pressure fluid of said miniaturized waste heat engine, at least one miniaturized heat converter using said heat source to evaporate a liquid into vapor, at least one expander converting said vapor into said useable energy, at least one oxygenator coupled to said expander including an air compressing wheel a first set of valves regulating the amount of said vapor into said expander, a second set of valves regulating the amount of said vapor into said expander, and into an imploding chamber, and into a radiator, at least one pump pressurizing said liquid, at least one fluid injector, at least one sub-controller system interfaced with at least a computerized control system regulating the opening and closing of both said sets of valves, at least one said imploding chamber condensing said vapor exiting said expander, at least one said radiator condensing said vapor exiting said expander, at least one pressure relief safety valve; and at least one thermally insulating vacuum jacket surrounding the body of a centrifugal gas nozzle.
