CT: A new type of thermodynamic cycle originating from extended application of the heat pipe principle is proposed and its thermal cycle is discussed from the viewpoint of theoretical thermal efficiency and Coefficient of Performance (COP). An idealized structure that will meet the basic function for thermal systems is also suggested. A significant advantage of these systems is their use with low-temperature energy sources found in nature or heat rejected from industrial sites.

N:1. – thermodynamic (adj) 1849: thermo: from comb. form of Greek thermos “hot, warm,” therme “heat”.
dynamic: 1817 as a term in philosophy; 1827 in the sense “pertaining to force producing motion”, from French dynamique introduced by German mathematician Gottfried Leibnitz (1646-1716) in 1691 from Greek dynamikos “powerful,” from dynamis “power,” from dynasthai “to be able, to have power, be strong enough,” which is of unknown origin. The figurative sense of “active, potent, energetic” is from 1856 (in Emerson).
– cycle (n): late 14c., from Late Latin cyclus, from Greek kyklos “circle, wheel, any circular body, circular motion, cycle of events,”Avestan caraiti “applies himself,” c’axra “chariot, wagon;” Greek polos “a round axis”, polein “move around;” Latin colere “to frequent, dwell in, to cultivate, move around,” cultus “tended, cultivated,” hence also “polished,” colonus “husbandman, tenant farmer, settler, colonist;”.
2. A succession of processes in a substance which involve changes especially in temperature, pressure, density, and entropy, which result in the return of the substance to its original condition, and in which the substance acts in general as a means of transformation of energy.
3. In the field of Thermodynamics: A procedure or arrangement in which some material goes through a cyclic process and one form of energy, such as heat at an elevated temperature from combustion of a fuel, is in part converted to another form, such as mechanical energy of a shaft, the remainder being rejected to a lower temperature sink.
