| titleOfInvention | Intrinsically irreversible heat engine |
| abstract | INTRINSICALLY IRREVERSIBLE HEAT ENGINE ABSTRACT OF THE DISCLOSURE A class of heat engines based on an intrinsically irreversible heat transfer process is disclosed. In a typical embodiment the engine comprises a compressible fluid that is cyclically compressed and expanded while at the same time being driven in reciprocal motion by a posi-tive displacement drive means. A second thermodynamic medium is maintained in imperfect thermal contact with the fluid and bears a broken thermodynamic symmetry with respect to the fluid. The second thermodynamic medium is a structure adapted to have a low fluid flow impedance with respect to the compressible fluid, and which is fur-ther adapted to be in only moderate thermal contact with the fluid. In operation, thermal energy is pumped along the second medium due to a phase lag between the cyclical heating and cooling of the fluid and the resulting heat conduction between the fluid and the medium. In a prefer-red embodiment the engine comprises an acoustical drive and a housing containing a gas which is driven at a reso-nant frequency so as to be maintained in a standing wave. Operation of the engine at acoustic frequencies improves the power density and coefficient of performance. The second thermodynamic medium can be coupled to suitable heat exchangers to utilize the engine as a simple refrig-eration device having no mechanical moving parts. Alter-natively, the engine is reversible in function so as to be utilizable as a prime mover by coupling it to suitable sources and sinks of heat. |
