Heat exchanger for a Stirling engine

A heat exchanger for a Stirling engine comprising:

• a domed cylinder having a domed portion and a cylindrical portion, the domed cylinder serving as a high-temperature cylinder and a regenerator housing of said Stirling engine;
• a cylindrical inner liner which is coaxially disposed inside said domed cylinder and which divides the inside of said domed cylinder into an expansion space inside of said inner liner and a regenerator space between the outer surface of said inner liner and the inner surface of said cylindrical portion of said domed cylinder;
• a cylindrical regenerator which is coaxially disposed with respect to said inner liner inside said regenerator space;
• a cylindrical cooler which is coaxially disposed with respect to said inner liner below said cylindrical regenerator, said cooler having a cylindrical inner surface which forms the outer periphery of a compression space of said Stirling engine;
• and
• a heater tube which is mounted on said domed cylinder so as to communicate between the upper portion of said expansion space and said regenerator space.
