A method of improving the thermal shock resistance of a honeycombed structure through which fluids flow and formed by joining a plurality of cellular segments to one another along their peripheral walls, by providing discontinuities through the joints formed between the adjoining segments in the direction of the fluid flow through the structure so as to lessen temperature differences occurring in the joint area, to provide the structure with greater flexibility and to act as crack arrestors lessening the transmission of stresses between adjoining segments and through the joints. In two preferred embodiments, the invention is practiced in forming a heat recovery wheel by joining a plurality of cellular segments to one another with cement which is striped to the segments so as to form a plurality of hollow, straight walled, channels extending essentially axially through some or all of the joint areas of the resulting wheel.
In a method of making a honeycombed structure having a plurality of open-ended, hollow cells which allow the passage of fluids therethrough from a first to a second outer surface thereof, from a plurality of cellular segments each having a pair of opposing honeycombed surfaces formed from a plurality of open-ended, hollow cells extending therethrough and peripheral side walls therearound, comprising the steps of forming said cellular segments and joining a peripheral wall of each of said segments to a peripheral wall of another so as to form a joint therebetween, the improvement comprising the step of:
A heat recovery wheel having a pair of opposing outer annular faces and a central axis therebetween, comprising:
