Thermal oscillation systems

A thermal oscillator for managing heat content within a cycling liquid-vapor stream, the oscillator comprising:

• a condenser having a plurality of isobaric, heat-conductive cooling channels operative to release condensation heat from a vapor component of the cycling liquid-vapor fluid stream so as to form condensate at a first temperature and a first pressure;
• a condensate expansion arrangement configured to adiabatically or isenthapically cool the condensate to a second temperature less than the first temperature and a second pressure less than the first pressure, forming a cooled condensate;
• and
• an isochoric heater pump comprising:
• a plurality of constant-volume heating chambers heated by the condensation heat and/or an external heat;
• at least one intake port to form at least one combined stream from an oscillation stream comprising the cooled condensate and at least one expanded input stream;
• and
• at least one outlet port configured to split the combined stream into a first oscillation stream and at least one second stream segment;
• wherein the heater pump vaporizes the cooled condensate into vapor during conveyance within the pump and wherein the split first oscillation stream undergoes condensation.

A method of heat management within a cycling liquid-vapor stream, the method comprising:

• releasing condensation heat isobarically from vapor of a first stream segment of the cycling liquid-vapor stream thereby producing condensate at a first temperature and a first pressure;
• expanding a second stream segment of the cycling liquid-vapor stream thereby producing an expanded liquid-vapor stream;
• combining the expanded liquid-vapor stream isochorically with the condensate thereby producing a combined liquid-vapor stream;
• and
• vaporizing the combined liquid-vapor stream isochorically with the condensation heat and/or an external heat.
