ABSTRACT:
A heater head assembly of the type useful in a hot gas engine is disclosed. The assembly has a plurality of tubes or passages providing a communicating connection for the gas between high temperature working chambers and regenerators. In one embodiment, manifold extensions are provided for each of the working chambers and regenerators and between which banks of heater tubes extend. Each of said manifolds contain at least one blind flow turn-around or reverter structure whereby hot gases traversing between a working chamber and a regenerator must travel the spacing therebetween a minimum of three times. Each of said tube banks are formed by uniting two plys of sheet metal along spaced pairs of parallel lines of brazing, the zone within each pair of brazing lines being expanded to define gas passages for said tube bank and the zone between pairs of brazing lines being perforated to admit cross-flow of a surrounding heating medium.
