Embodiment Construction

[0014] The present invention will be explained in detail below with reference to the accompanying drawings.

[0015] refer to figure 1 and figure 2 , a Stirling engine with star-shaped connecting rod transmission, including an engine base 1, the engine base 1 is a hollow multi-faceted prism structure, and three radial stepped holes are processed on its side, and some holes are processed in the axial direction. Cooling hole; the power piston 7 is installed in the smallest part of the aperture of the engine substrate 1 stepped hole, and there is a gas sealing device on it, and the support column 11 is connected with the internal thread of the middle aperture part of the engine substrate 1 stepped hole through the external thread on its large end, There is a circle of through holes on the large end of the support column 11, so that the working medium can circulate through these holes. The largest part of the stepped hole diameter of the engine substrate 1 is processed with inte...

Abstract

The invention discloses a Stirling engine employing a star connecting rod transmission mode. An integrated substrate is adopted, each working cavity required by Stirling circulation is formed in the substrate in form of step hole, a plurality of pistons are driven by force generated by the heating expansion and the cooling shrinkage of a free piston type Stirling circulating working medium to reciprocally move, and are coupled together through a star crank-connecting rod mechanism to drive an output shaft to continuously rotate. According to the Stirling engine, the integrated engine substrate is adopted, so that the whole Stirling engine is stable in structure, and works reliably, and the arrangement of a radiation pipeline is facilitated; a plurality of Stirling working modules are connected in parallel in a star arrangement manner, so that the space is saved, and the power density of the whole engine is improved; all the moving parts are packaged between an upper end cover and a lower end cover, so that the service life of the whole engine is prolonged.

Description

technical field [0001] The invention relates to a Stirling engine, in particular to a Stirling engine driven by star-shaped connecting rods. Background technique [0002] The Stirling engine was invented in 1816 by Robert Stirling, a pastor in London. It is an external combustion engine that generates power by expanding the gas when it is heated and compressing it when it is cold. Its actual efficiency is almost equal to the theoretical one. The maximum efficiency (Carnot cycle efficiency), at the same time, there is no deflagration in the working process, and the noise is very small, so it has received extensive attention. However, due to the rapid development of internal combustion engines, the Stirling engine has faded out of the sight of industrial applications, and only a few There are applications in the military field. Until recent years, civil gas sealing technology has been developed, and the high-quality chemical energy required by internal combustion engines has ...
