Temperature differential engine device

摘要

A temperature differential engine device includes a low-boiling-point medium steam turbine (1), a heat absorber (2), a thermal-insulating type low-temperature countercurrent heat exchanger (3), a circulating pump (4), and a refrigerating system (5) which are interconnected to constitute a closed circulating system filled with low-boiling-point medium fluid. The low-boiling-point medium steam turbine (1) and the heat absorber (2) constitute a low-density-medium heat-absorbing working system, and the circulating pump (4) and the refrigerating system (5) constitute a high-density-medium refrigerating-circulating system. The temperature differential engine device can transfer thermal energy into mechanical energy.

1. A temperature differential engine device, characterized in that, it includes a low-boiling-point medium steam turbine (1), a heat absorber (2), a thermal-insulating low-temperature countercurrent heat exchanger (3) coupled to the heat absorber, a circulating pump (4) coupled to the heat exchanger, and a refrigerating system (5) coupled to the heat exchanger, which are interconnected to constitute a closed circulating system for a low-boiling-point medium within, wherein:
a. the low-boiling-point medium steam turbine (1) and the heat absorber (2) constitute a low-density-medium heat-absorbing working system, and the circulating pump (4) and the refrigerating system (5) constitute a high-density-medium refrigerating-circulating system; transverse heat transfer is realized through the thermal-insulating low-temperature countercurrent heat exchanger (3); b. the thermal-insulating low-temperature countercurrent heat exchanger (3) comprises a high-temperature end (A) a low-temperature end (B), one or more heat-insulating layers, and a heat exchanger wall divided into a plurality of heat-insulated sections by the one or more heat-insulating layers within the heat exchanger; and the medium exchange heat transversely within each heat-insulated section with each other via the heat exchanger wall; c. the heat absorber (2) is connected to the low-boiling-point medium steam turbine (1) to compensate for thermal energy consumption by the low-boiling-point medium steam turbine (1).
