A heat engine is constructed from sheet metal and the like. The heat engine has an outer container and inner container which contains a displacer and a power piston. A plurality of positioning members are provided to dimensionally stabilize the inner and outer containers. By providing positioning members that extend between the inner and the outer containers, a sandwiched construction is obtained which allows the inner and outer containers to reinforce each other thus permitting the use of thin walled containers and improving the thermal efficiency of the heat engine and decreasing the weight of the heat engine.

[ I claim:] [1.]1. A heat engine body for a heat engine comprising:(a) a container defining a sealed region within which a working fluid is circulated when the heat engine is in use, the sealed region having first and second ends which are in fluid flow communication via a working fluid passageway,

[ I claim:] [1.]1. A heat engine body for a heat engine comprising:(a) a container defining a sealed region within which a working fluid is circulated when the heat engine is in use, the sealed region having first and second ends which are in fluid flow communication via a working fluid passageway, the first end is at a different temperature than the second end when the heat engine is in use; and,(b) a heat exchanger mounted in a portion of the sealed region through which the working fluid travels, the heat exchanger comprising at least one fin extending transversely to the longitudinal direction and having first and second opposed sides and openings there through whereby working fluid flows through the openings from the first opposed side to the second opposed side via the openings to enhance heat transfer between the working fluid and the heat exchanger, when the heat engine is in use.
