HEAT ENGINE REGENERATOR AND STIRLING ENGINE USING THE REGENERATOR

摘要

Provided is a regenerator (10), for use in a heat engine, configured to receive and store heat from a high-temperature gas flowing from a high-temperature space into the regenerator, and to provide the heat to a low-temperature fluid flowing from a low-temperature space into the regenerator. The regenerator includes a large number of layered metal meshes (11). Each metal mesh (11) includes a large number of mutually parallel longitudinal strands (13V) and a large number of mutually parallel lateral strands (13H) perpendicular to the longitudinal strands. The metal meshes (11) are layered such that each metal mesh is sequentially rotated in a same direction by a fixed angle with respect to an immediately previously layered metal mesh.
