Solar sterling generator

Abstract

The invention provides a solar sterling generator. A plurality of symmetrically-distributed rotor support frame mounting grooves are arranged on the inner wall of a generator body of the solar sterling generator, two rotor support frames are arranged in the generator body respectively from two ends of the generator body along the mounting grooves and fixed together by a plurality of groups of fastening screws, and the generator body, the rotor support frames and rotors are fixed together. Central lines of pin holes at two ends of a connecting rod of a piston group are perpendicular to each other, assembly clearances are arranged at a piston connection part and a guide block connection part, and the piston group has the functions of automatically compensating radial and tangential displacements of an air cylinder, therefore, the assembly difficulty in the production process is reduced, and the reliable degree in the operation process is improved. By comprehensively adopting latest technologies of a countercurrent heat exchanging type regenerator, an annular heat exchanger, and the like, the whole generator has a compact structure and small size. By adopting an air cooling manner for heat dissipation, the solar sterling generator can be widely applied to water-deficient areas.

Description

Technical field

[0001] The invention relates to a Stirling generator, in particular to a solar Stirling generator. Background technique

[0002] Energy problems plague countries all over the world, and efficient use of solar energy is an inevitable choice. At present, there are three types of solar thermal power generation: tower type, trough type, and dish type. The disc type has the highest thermal efficiency, the smallest footprint, and the most flexible layout. It is the most promising way for development, but it is subject to the lack of major breakthroughs in Stirling heat engine technology.

[0003] The Stirling reversible heat engine, which applied for a Chinese invention patent on December 19, 2007, solved the two major problems of complex structure and difficult sealing that hindered the development of Stirling heat engines; The heat exchanger greatly reduces the cost and improves the heat recovery efficiency; a ring heat exchanger for a Stirling heat engine desc...
