Abstract
A regenerative heat exchanger in which a compact arrangement of alternating thermally conductive and thermally insulating solid layers have an array of communicating passages therethrough. One of the outer thermally conductive layers is heated and the other is cooled. The intermediate thermally conductive layer(s) has a regenerative function when flow is alternated through the passages. Although each passage is preferably small, the total number of passages in the array is such as to give a large combined cross-sectional area for heat transfer providing improved overall performance and efficiency when incorporated in stirling and other heat engines without sacrificing structural integrity.
