A stirling engine.

摘要

A heat exchanger for a Stirling engine has a domed cylinder (15) which serves as a high-temperature cylinder and a regenerator housing. The domed cylinder has a smoothly-changing cross-sectional shape so that stress concentrations will not develop therein. A thin inner liner (16) which is inserted into the domed cylinder divides the inside of the domed cylinder into an expansion space (1 a) and a regenerator space. A cylindrical regenerator - (5) is coaxially disposed inside the regenerator space. A cylindrical cooler (6) is coaxially disposed below the regenerator with its inner surface forming the outer periphery of the compression space (3a) of the engine. The expansion space (1a) and the regenerator space are connected to one another by a plurality of heater tubes (4) which are secured to the domed cylinder.
