1. A heat engine body comprising:
- (a) a container defining a sealed region within which a working fluid is circulated when the heat engine body is in use, the sealed region having spaced apart 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 body is in use; and
, (b) a heat exchanger comprising at least one member defining a plurality of openings having associated louvres which are configured and arranged to cause at least a portion of a fluid to flow through the openings as the fluid flows through the heat exchanger.

18. A heat engine body 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) the heat engine having a plurality of fins which are prepared by stamping.

19. A heat exchanger means capable of being mounted in an fluid flow passage which is located between first and second walls, the walls having a first end and a spaced apart second end, the heat exchanger means comprising fin means having first and second opposed sides and first directing means for generating a main flow of fluid through the fin means as the fluid flows from the first end to the second end and secondary directing means for generating a secondary fluid flow which passes through at least some of the first directing means whereby the heat transfer between the fluid and the heat exchanger means is enhanced.

20. A heat engine body comprising:
-
(a) inner and outer spaced apart longitudinally extending walls, at least one of the inner and outer walls being of a thin walled construction, the inner wall surrounding a cavity, each of the inner and outer wall having longitudinally spaced apart first and second ends, the first end is at a different temperature than the second end when the heat engine is in use, the first and second ends in fluid flow communication via a passageway, the first and second ends and the passageway defining a sealed region within which a working fluid is circulated when the heat engine body is in use; and
,(b) positioning members for dimensionally stabilizing the one of the inner and outer wall which is of a thin walled construction.
