Abstract

See full text

A Stirling engine includes a working cylinder defining a working cylinder chamber with a reciprocatingly-arranged working piston and a heater fluidly communicating with the working cylinder chamber through a working gas channel. The engine includes a first heat exchanger extending from a head of a displacer cylinder into the heater, a second heat exchanger formed by a regenerator arranged outside the heater, and a third heat exchanger formed by a cooler arranged between the regenerator and the working cylinder chamber. At any point along the working gas channel, as seen cross-wise to an assumed working gas flow direction through the working gas channel, the cross section area of the working gas channel defined by the first, second and third heat exchangers is within the range of the medium cross section area of the working gas channel +/−10%.
