Abstract
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.
