[0048] Along the downward direction of the height of the annular outer stepped column 105 , a wave-shaped groove is dug on the annular outer stepped column 105 , which is called the outer wave-shaped groove 1051 for short. The center line of groove symmetry of the outer corrugated groove 1051 is a wave line, the length of its major axis is equal to the height of the annular outer stepped column 105, and the length of its minor axis is equal to the fluctuation amplitude of the outer wave groove 1051. Excavating the outer corrugated groove 1051 on the annular outer stepped column 105, its minor axis intersects with the circumferential surface of the annular outer stepped column 105 diameter, the opening 1052 of the outer wave groove 1051 is positioned on the circumferential surface of the annular outer stepped column 105 diameter, it The depth is close to the inner diameter curved surface 109 of the annular outer step 102, and its wave surface is perpendicular to the circumferent...

[0050] Along the downward direction of the height of the annular inner stepped column 106 , a wave-shaped groove is dug on the annular inner stepped column 106 , which is called the inner wave-shaped groove 1061 for short. The groove symmetry center line of the inner wave groove 1061 is a wave line, the length of its major axis is equal to the height of the annular inner step column 106, and the length of its minor axis is equal to the fluctuation range of the inner wave groove 1061. The inner wave groove 1061 excavated on the annular inner stepped column 106, its short axis intersects with the circumferential surface of the inner diameter of the annular inner stepped column 106, the opening 1062 of the inner wave groove 1061 is located on the inner diameter curved surface 110 of the annular inner stepped column 106, its The depth is close to the circular inner step 103 diameter curved surface 112, and its wave surface is perpendicular to the circumferential surface of the inne...

Abstract

The invention discloses a stirling engine. Compared with the prior art, a heater 25 of the stirling engine consists of a hollow cylinder 1, a circular ring 16 and other circular rings, an inner circular ring 15 and other inner circular rings, a sleeve 15 and a semispherical shell 13, the composite force of the air pressure of the air as a working substance on the heater 25 points to an axial line of the heater 25 and a heat isolation tube 8 is added in a cylinder 3; the design lowers the requirements of the cylinder 3 and the heater 25 of the stirling engine on the mechanical strength of advanced heat resistance alloy at high temperature, and meanwhile lowers the heat loss and temperature of the cylinder 3 as well as stabilizes the temperature thereof. Therefore, cylinder 3 and heater 25 can be made of advanced heat resistance alloy of a lower level to attain the same effect as using the prior advanced heat resistance alloy of a higher level, thus reducing the manufacture cost of the stirling engine, improving the heat efficiency and service life of the stirling engine. The stirling engine can use the high temperature thermal energy produced by fuel of solid, liquid or gas state and focused solar power as well as liquid or gaseous fluid with high temperature thermal energy. The stirling engine has the characteristics of wide range of fuel and thermal sources, high heat efficiency and environmental protection, and is widely developed and applied in future social production practice.
