Claims

[Scope of utility model registration request]

It has a large number of heater tubes connecting the cylinder and the heat storage housing, and the cylinder side, the heat storage housing side, or both sides are connected via a manifold, and the manifold is integrally formed with the cylinder or the heat storage housing, and the By making the opening of the connection part wide and allowing the flow path of the working gas to smoothly expand from the inner diameter of the cylinder or heat storage housing without being constricted, the cross-sectional area of the working gas flow path can be changed smoothly. A heater head of a hot gas engine in which a fin is provided in the heater tube so as to divide the heater tube located within the inner diameter width of the cylinder or the inner diameter width of the regenerator housing into two chambers at the center. .
