Abstract

A Stirling engine comprising: a crank case (1) with a crank shaft (2) arranged therein, a displacer cylinder (3) with a reciprocatingly arranged displacer piston (4) therein, said displacer piston (4) being connected to said crank shaft (2) via a connecting rod (5) extending through a first end of said displacer cylinder (3), and wherein the displacer cylinder (3) defines a hot chamber (6) and a cool chamber (7) separated by the displacer piston (4), a working cylinder (8) with a reciprocatingly arranged working piston (9) therein, said working piston (9) being connected to said crank shaft (2) via a connecting rod (10) extending through a first end of the working cylinder (8), a heater device (14), arranged at a second end of said displacer cylinder (3) opposite to said first end and configured to heat a working gas which is present in the hot chamber (6) of the displacer cylinder (3) and in fluid communication with the working cylinder chamber (11) through a working gas channel which comprises a first heat exchanger (16) extending from a head (19) of the displacer cylinder (3) into the heater device (14), and a second heat exchanger (17) formed by a regenerator arranged outside the heater device (14), wherein the first heat exchanger (16) comprises a plurality of tubes (18) which extend from the hot chamber (6) of the displacer cylinder (3) through the heater device (14) and further towards the regenerator (17). There is provided a transition flow element (21) between the first heat exchanger (16) and the regenerator (17), wherein the transition flow element (17) is configured to spread the flow of gas in at least one direction from each individual tube (18) of the first heat exchanger (16) to the regenerator (17), wherein the transition flow element (21) has a plurality of discrete outlet openings (26) that face the regenerator (17).
