STIRLING ENGINE

WIPO Patent Application WO/2011/070786

A1

Disclosed is a Stirling engine which can effectively recover heat from an exhaust gas flowing through a flue, and which can connect a heater (10) and a regenerator (5) by means of a working gas tube without providing a passage separation unit. A heater (10) is configured from a heater head (10a) and a heat transfer tube group (A). Provided in the heater head (10a) are a first through-hole group (30R) which communicates with a high-temperature space (3), and a second through-hole group (30S) which communicates with the regenerator (5). The first through-hole group (30R) is formed nearer to the center region of the heater head (10a) than the second through-hole group (30S). U-shaped tubes (11, 12, 13) constituting a heat transfer tube group (A) are mounted at one end in the through-holes constituting the first through-hole group (30R), and at the other end in the through-holes constituting the second through-hole group (30S). Parallel exhaust gas passages are formed between the U-shaped tubes (11, 12, 13) by arranging the U-shaped tubes (11, 12, 13) in a row direction.
