Abstract:
A heat exchanger having a stack of parallel pockets each formed between superimposed plates each providing a set of ribs having parallel straight sections connected by parallel curved sections, each pocket having the ribs of one flanking plate slightly offset with respect to the ribs of the other flanking plate so that the ribs of one plate provide spacers holding the flanking plates apart while dividing the pockets into substantially parallel U-shaped flow gas flow paths which extend between a gas inlet, provided along one corner region of the stack, and a gas outlet provided along a different corner region of the stack, the ribs of alternate plates being in registration with one another and being almost in registration with the ribs of the remaining plates which are also in registration with one another so that the corresponding parallel U-shaped gas flow paths in all of the pockets are in substantial registration with one another over the greater part of their lengths.
