AI Technical Summary
The existing heat engine system is low in efficiency, mainly due to the low thermal efficiency during Rankine cycle and steam turbine power generation.
A completely closed and well-conductive heat machine is designed, using the liquid and saturated steam of a single working fluid, and the circulation process of the working fluid is realized through a special compressor and switching mechanism, thereby converting the thermal energy of the saturated steam into gravity potential energy. And absorb external heat through liquid vaporization.
The efficiency of the heat engine is improved. By converting the difference between the gravitational potential energy of the liquid and the initial kinetic energy of the piston into heat, the external heat is absorbed while the temperature remains unchanged, which significantly improves the energy utilization efficiency of the heat engine.

Abstract
Description
Technical Field
[0001] The invention relates to an energy mechanical device, in particular to a high-efficiency heat engine. Background Art
[0002] Most existing heat engine systems are Rankine cycles, which usually generate electricity through a steam turbine and dissipate heat through a condenser, and have low thermal efficiency. Summary of the invention
[0003] The purpose of the present invention is to improve the efficiency of current heat engines and to propose a heat engine design scheme.
[0004] There is a completely enclosed outer wall (5) with good thermal conductivity, inside which is a single working medium (6), with its liquid at the bottom and its saturated steam at the top, and there is also a special compressor (with four switches (1), (2), (3), (4)).
[0005] Take a special case to illustrate and prove that this heat engine may be more efficient than existing heat engines.
[0006] At the beginning, switches (1) and (2) are open, and (3) and (4) are closed. The system first gives the piston a very small force to make it move slowly to the right. Since the space on the right side of the piston is closed and the overall thermal conductivity is good, the temperature of the system is kept equal to the ambient temperature, so the pressure is the saturated vapor pressure of the working fluid at this temperature. The left side of the piston is connected to the large space inside the outer wall, and the pressure is also the saturated vapor pressure at this temperature. Therefore, under this ideal condition, the piston can move to the right. At this time, turn on switches (3) and (4), and the liquid flows out from (4). Close (1) and (2), and the process can be repeated. In this process, the thermal energy of the saturated steam is converted into its gravitational potential energy, while the overall temperature remains unchanged. The liquid vaporizes and absorbs heat, so it absorbs heat from the outside. The amount of heat is the difference between the gravitational potential energy of the liquid and the kinetic energy given to the piston at the beginning. Therefore, as long as the gravitational potential energy of the compressed gas is greater than the kinetic energy given to the piston at the beginning, it will inevitably absorb heat from the outside. Obviously, when the situation changes slightly, as long as the difference between the gravitational potential energy of the liquid and the kinetic energy initially given to the piston is satisfied, heat can be absorbed from the environment. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 It is a high efficiency heat engine diagram.
