Embodiment Construction

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

[0013] Assume that the working temperature range of the 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, and 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...

Abstract

A novel Stirling heat engine taking air, water or a refrigerant as a working medium. The engine comprises such main components as two or more heat-releasing cylinders (1, 2), two or more heat-absorbing cylinders (3, 4), an expander (7) or a dual-use cylinder, a three-way valve (8) or a multi-way valve, a heat exchange system (6), and a sealed container (5). The engine utilizes pressure from inside the sealed container to do work. This novel Stirling heat engine can use the ambient atmospheric pressure to do work, so that the output work and efficiency are both higher than those of a conventional heat engine.

Description

technical field [0001] The invention provides a Stirling heat engine using air, hydrogen or refrigerant as working fluid. This Stirling heat engine includes main components such as an expander, a motor, a cylinder, and a sealed container. This 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 Stirling heat engine capable of using ambient atmospheric pressure to perform work. This heat engine includes two or more isothermal exothermic compression working cylinders, expanders or double-acting cylinders, three-wa...
