A heat engine using air, water or a refrigerant as a working medium, comprising two kinds of thermodynamic cycles, each kind of thermodynamic cycle can realize power output; a thermodynamic cycle 1 is similar to the stirling cycle and consists of four processes, including an isothermal exothermic compression process, an isovolumetric endothermic heating process, an isothermal endothermic expansion process and an isovolumetric exothermic cooling process; thermodynamic cycle 1 consists of two loops, and the structure of the thermodynamic cycle 1 comprises a cylinder #1, a cylinder #2, a cylinder #3, an expansion machine or a double-shaft double-acting cylinder and a sealing container; a thermodynamic cycle 2 consists of three processes, including an isothermal endothermic expansion work process, an isobaric exothermic compression process and an isovolumetric endothermic heating process; thermodynamic cycle 2 consists of two loops, and the structure of the thermodynamic cycle 2 comprises a heat insulating cylinder #1, a heat insulating cylinder #2, a condenser #1, a condenser #2, a cylinder #3, an expansion machine or a double-shaft double-acting cylinder and a sealing container. Such a heat engine can do work by means of the pressure inside the sealing container, and therefore the output work and efficiency of the heat engine are both higher than the output work and efficiency of conventional heat engines. |
