Abstract
An impingement plate type heat exchanger for exchanging heat between first and second fluids in different paths. A stack of plates include impingement orifice plates and heat exchange orifice plates defining first and second tortuous flow paths generally parallel to each other and generally perpendicularly through the plates for the first and second fluids, respectively. The heat exchange orifice plates span both flow paths, and there are more impingement orifice plates in one flow path than the other to provide a more tortuous flow path for one fluid than the other. Partition plates have relatively large openings surrounding arrays of orifices in the impingement orifice plates and the heat exchange orifice plates to define the boundaries of the flow paths.
