Title:
STIRLING ENGINE THERMAL SYSTEM IMPROVEMENTS
Document Type and Number:
WIPO Patent Application WO2001065099
Kind Code:
A3
Abstract:
A thermal cycle engine (96) having a heat exchanger for transferring thermal energy across the heater head (100) from a heated external fluid to the working fluid. The heat exchanger has a set of heat transfer pins (124) each having an axis directed away from the cylindrical wall of the expansion cylinder (115), or, alternatively, a set of fins substantially aligned with the axis of the expansion cylinder. The height and density of the heat transfer pins (124) may vary with distance in the direction of the flow path, and the pin structure may be fabricated by stacking perforated rings in contact with a heater head. A ring burner supplements the main combustor for supplying additional fuel to cause additional combustion of the exhaust gas. A regenerator (134) for the thermal cycle engine (96) has a random network of fibers formed to fill a specified volume and a material for cross-linking the fibers at points of close contact between fibers of the network.
