Patent Images
1. A heat engine body comprising:
- (a) a container defining a sealed region within which a working fluid is circulated when the heal engine is in use, the sealed region having a first chamber and a second chamber, the first and second chambers being in fluid flow communication via a working fluid passageway;
(b) at least one fin, having first and second opposed sides and positioned exterior of the second chamber; and
, (c) a fan mounted in fluid flow communication with the at least one fin.

Abstract
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.
