Abstract:
A regenerator heat exchange device comprising:a rotatable frame having a rotation axis; andan energy transfer matrix comprising a plurality of removable, interchangeable heat exchange segments, said segments including at least two types, one type sized to provide an inner segment and the other type sized to provide an outer segment, the two types being shaped so as to cooperate with one another in said frame;wherein the frame includes:(a) a hub section;(b) a plurality of spokes extending from said hub section, each spoke having (i) a first spoke section having an I-beam cross-section adapted to receive on each side of the first spoke section an edge of a first of said types of segments as the segment is moved radially with respect to the axis of the frame so as to lock the segment in said frame, and (ii) a second spoke section having a T-bar cross section adapted to receive on each side of the second spoke section an edge of a second of said types of segments as the segment is moved axially with respect to the axis of the frame;(c) a rim assembly coupled to the plurality of spokes; and(d) a plurality of bars, constructed and arranged so as to secure the edge of adjacent ones of the second types of segments in the frame.
