REGENERATIVE HEAT EXCHANGER FOR MICRO GAS TURBINE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a high-performance regenerative heat exchanger for a micro gas turbine. SOLUTION: A passage 5 of an exhaust C of the turbine and a passage 6 of a compressed air D are formed into an adjoining layers, the respective passages 5 and 6 are filled with helical springs 8 as heat transmission members, and the passages 5 and 6 are annually formed about a virtual extension line of the rotation axis of the turbine.
