ABSTRACT:
A heat exchange assembly and method for making same is disclosed which is useful for Stirling engine heater head constructions. The assembly is comprised entirely of a low cost extrudable material, such as silicon, which when fused in a carburizing furnace provides a rigid highly durable ceramic. Heater tubes are arranged within a chamber, the tubes carry ambient pressure high temperature combusted gases and the chamber containing high pressure lower temperature working gases about the exterior of each tube.
Heat exchange can additionally be improved by increasing the exterior surface area of each tube relative to the interior surface thereof.
