ABSTRACT:
A heater head for use in hot gas engine is formed using improved heat transfer structures. The heat transfer structures used in the heater head are formed of an oxidation resistant enclosure enclosing a tube of high strength, gas impermeable material. A chamber is formed between the enclosure and the tube, and filled with a metal or alloy which is liquid at the operating temperature of the heater head. The structure transfers combustion heat rapidly from the oxidation resistant metal to the strong, gas impermeable tube via the liquid metal. The strong gas impermeable tube is filled with working gas, such as hydrogen or helium maintained at a high pressure.
