Patent attributes
A nested dish-plate heat exchanger is disclosed wherein the heat exchanger core is comprised of a plurality of first and second heat exchanger plates arranged in alternating stacked relationship. The first and second heat exchanger plates each have a pair of openings formed in the base portion of the plates and a pair of upwardly protruding boss portions and a pair of downwardly protruding bosses each having a corresponding opening formed therein. The first and second heat exchanger plates are arranged in an alternating stacked relationship wherein each subsequent first or second heat exchanger plate is rotation 180 degrees with respect to the previous first or second heat exchanger plate in the stack, the arrangement providing a plurality of first, second and third fluid flow passages therebetween such that each of the second and third fluid flow passages are in heat transfer relationship with the first fluid flow passages.
