Multi-ring connected Stirling reversible heat engine

Abstract

The invention relates to a multi-ring connected Stirling reversible heat engine. Cylinders at the heat inflow end of the engine are communicated with cylinders at the heat outflow end of the engine, which correspond to piston groups arranged at intervals through heaters, heat exchange regenerators and radiators to form working cavities; the working cavities and the piston groups are connected alternately to form a plurality of closed connecting rings; the connecting directions of all the closed connecting rings are consistent; two working cavities with the phase difference pi are respectively communicated with two heat exchange channels of the same heat exchange regenerator; the whole engine is provided with at least two closed connecting rings; and each closed connecting ring is formed by connecting at least three piston groups and at least three working cavities alternately. By combining the heat exchange regenerators with the high-efficiency radiators, the output power of a single working cavity is increased; the inherent advantages of simple structure, high efficiency, low noise and the like of the Stirling heat engine are fully exerted; and manufacturing cost and using cost are lower than those of an internal combustion engine, a steam turbine and a gas turbine.

Description

Technical field [0001] The invention relates to a Stirling heat engine, in particular to a multi-ring connection type Stirling reversible heat engine. Background technique [0002] In 1995, the International Stirling Engine Conference held in Tokyo, Japan predicted that the 21st century would be the century of Stirling engines! There has been an upsurge in the study of Stirling heat engines all over the world, and the technology of Stirling heat engines is on the eve of a major breakthrough. [0003] In June 2011, the Stirling reversible heat engine obtained the Chinese invention patent, marking the emergence of a new type of Stirling heat engine. However, there are still many technical issues that need to be resolved. [0004] Each constant volume process and each constant temperature process of the four-cavity Stirling reversible heat engine occupy a phase angle of π / 2. This coincidence gives people the impression that the four-cavity Stirling reversible heat engine is ...

Problems solved by technology

The reason is that the volume of the working chamber connected by the double ring changes greatly, and the pressure fluctuation also increases accordingly.
