Abstract
A matrix structure for a rotary regenerator includes a hub and a plurality of matrix elements, each secured at one end to the outer periphery of the hub, and spirally wound in an involute configuration about the hub and fixed together, as by brazing, into a rigid, elastic structure. Each of the matrix elements includes, in series, a corrugated strip of predetermined length, an inner shim strip extending along one side of the corrugated strip for approximately half of the length thereof, the corrugated strip having a return bent portion and a folded back portion which extends along the opposite side of the inner shim strip and, an outer shim strip extending along the opposite side of the fold-back portion from the inner shim strip and around the return bent portion, the portion of the outer shim strip extending around the return bent portion serving as the means by which the matrix element is secured to the hub.
