Abstract:
1. A heater head assembly for a Stirling cycle system, the heater head assembly comprising: a body being of unitary construction, with a conically shaped body portion and a cylindrically shaped body portion being of one-piece construction and together defining an interior volume: the conically shaped body portion having a planar surface constructed to pass heat when the heater head assembly is coupled to a heat source, a domed shaped interior surface, and a plurality of passageways being formed at least in part in the conically shaped portion; and the cylindrically shaped body portion having first and second sections, the first section of the cylindrically shaped body portion having a cylindrical interior surface, and the second section of the cylindrically shaped body portion having rejector members extending radially inward into the interior volume with innermost portions thereof defining a cylindrical inward surface concentric with the cylindrical interior surface of the first section of the cylindrical shaped body portion; regenerator material having a first surface positioned against the cylindrical interior surface of the first section of the cylindrically shaped body portion, the regenerator material extending radially inward into the interior volume and having an cylindrical inward second surface in inward positional alignment with the cylindrical inward surface of the rejector members; and a cylindrical sleeve having an outer diameter sized to be adjacent to the cylindrical inward surface of the rejector members and to the cylindrical inward second surface of the regenerator material.
