Abstract

The invention relates to a novel stirling engine comprising a center rotating shaft for outputting power and a starting mechanism arranged at the output end of the center rotating shaft, wherein a rotating wheel gas transferring mechanism is arranged at one end of the center rotating shaft and comprises a cylindrical casing, heat-insulating side pads at the front end and the rear end of the sealing casing, a work doing gas medium sealed in the casing cavity, a semi-cylindrical gas transfer wheel and a labyrinth sealing device for sealing various cavities of the casing; the casing consists of an upper semi-cylindrical heat cavity casing, a lower semi-cylindrical heat cavity casing and a semi-cylindrical cold cavity casing; central heat-insulating sealing pads are respectively connected between the upper heat cavity casing and the cold cavity casing and between the lower heat cavity casing and the cold cavity casing; the heat cavity casings are used for heating the work doing gas medium; the cold cavity casing is used for cooling the work doing gas medium; an air operated mechanism is arranged on the rotating wheel gas transferring mechanism of the center rotating shaft, which is close to the starting mechanism; and a heat energy regenerator set, an air guide pipe set and a one-way gas distribution valve bank which are communicated with the casing and the air operated mechanism are sequentially arranged between the rotating wheel gas transferring mechanism and the air operated mechanism.

Description

【Technical field】 [0001] The invention relates to engine equipment, in particular to a novel Stirling engine. 【Background technique】 [0002] The Stirling engine is a closed cycle developed by the Scottish pastor Robert Stirling based on the Carnot cycle theory in the early 19th century, in which the gas is periodically compressed and expanded at different temperatures by external heating. The external combustion engine is characterized in that one end of the cylinder of the engine is a hot chamber and the other end is a cold chamber, and a certain volume of working fluid is filled in the closed cylinder. During the working process, the fuel is continuously burned in the combustion chamber outside the cylinder. Through the heater, the working fluid is heated and expanded rapidly in the high-temperature hot chamber, and then flows into the low-temperature cold chamber for compression. The pressure difference generated by the working fluid in the process of continuous thermal ...
