Embodiment Construction

[0012] A specific embodiment is introduced below, and the specific implementation manner is not limited to this one example.

[0013] Suppose the working temperature range of the new heat engine is 300K~600K, the working medium is air, and the working pressure is: high pressure (inlet pressure of expander) 0.404MPa, low pressure (pressure after equal volume heat release) 0.105MPa, the airtight container is filled with air, the pressure is 0.202MPa.

[0014] The pressure of the working medium at the inlet of the expander is 0.404MPa, and the temperature is 600K. When the working medium flows through the expander, it is an isothermal endothermic expansion process. After the working medium flows through the expander, the pressure drops to 0.21MPa, and the temperature is 600K.

[0015] After leaving the expander, the working fluid enters an isothermal exothermic compression work cylinder. The cylinder is installed in a sealed container, and the steam inlet valve and the steam exh...

Abstract

The invention provides a novel stirling heat engine which takes air, hydrogen or a refrigerating agent as a working medium. The novel stirling heat engine comprises such main components as an expander, an engine, a cylinder and a sealed container. The novel stirling heat engine can do work by using ambient atmosphere pressure, so that the output power and the efficiency of the novel stirling heat engine are higher than those of a conventional heat engine.

Description

technical field [0001] The invention provides a novel Stirling heat engine using air, hydrogen or refrigerant as working fluid. This novel Stirling heat engine includes main components such as an expander, a motor, a cylinder, and a sealed container. This new type of Stirling heat engine can use ambient atmospheric pressure to do work, so its output work and efficiency are higher than conventional heat engines. Background technique [0002] We know that conventional heat engines consume more energy, and the world is facing the problems of global warming and the depletion of fossil fuels. Conventional Stirling heat engines cannot use ambient atmospheric pressure to do work. Contents of the invention [0003] In order to solve the above problems, the present invention provides a novel Stirling heat engine capable of using ambient atmospheric pressure to perform work. This new type of heat engine includes two or more isothermal exothermic compression working cylinders, expa...
