ABSTRACT:
The several embodiments of a recuperator structure herein defines a matrix consisting of a multiplicity of elongated hollow tubes and solid rods formed of a glass ceramic material that is thermally crystallizable to a low expansion glass-ceramic. In one embodiment, each of the tubes is sealed at each end and contains an expansible fluid medium. Each of the tubes has a portion intermediate the ends thereof which is substantially straight. Pluralities of the multiplicity of tubes are tightly packed into a first plurality of layers with the axes of the intermediate portions of the tubes in each layer essentially parallel to each other. The first plurality of layers are arranged with the straight intermediate tube portions thereof in a stacked array with respect to each other, and with the axes of the intermediate portions of the tubes in each layer essentially parallel to the axes of the corresponding intermediate tube portions in the other first plurality of layers. This enables the formation of a first series of parallel passageways when the sealed ends of the tubes in the first plurality of layers are opened to receive a first fluid. Each layer of the first plurality of layers of tubes is spaced from at least one of the adjacent first plurality layers in the array by interposing spacer means between the layers being spaced.
