Patent ID: 8191615

Claim:
A heat exchanger system, comprising: a first heat exchanger, comprising: a first module comprised of a first spaced apart plate, a second spaced apart plate, a first intermediate plate, a second intermediate plate and a first module fin, wherein said first and second intermediate plates are back-to-back, identical to one another and different from said spaced apart plates, which themselves are identical, each of said intermediate plates having a plurality of alternating ribs and grooves, wherein said ribs of said back-to-back plates together form a first fluid conduit for a first fluid and said grooves of said individual intermediate plates together with said first and second intermediate plates form a second fluid conduit for a second fluid, wherein said first and second fluid conduits share a common wall, wherein said first spaced apart plate supports said fin directly thereon, said fin transverse to said first and second fluid conduits, said fin and at least said first spaced apart plate forming a third fluid conduit for a third fluid, said third fluid conduit transverse to said first fluid conduit and said second fluid conduit, wherein said first, second and third fluids are in thermal communication with one another through said plates, but not in fluid communication with one another and said fluids are different from one another; at least a second module, said second module comprised of a second module fin, identical to said first module fin, in direct contact with said second spaced apart plate of said first module and a second module first spaced apart plate to form a second module fluid conduit for said third fluid, said second module first spaced apart plate in direct contact with a second module first intermediate plate, said second module first spaced apart plate and said second module first intermediate plate together forming a second module second fluid conduit for said second fluid, said second module first intermediate plate in direct contact with a second module second intermediate plate, said second module intermediate plates being back-to-back and identical, each of said second module intermediate plates having a plurality of alternating ribs and grooves, wherein said ribs of said back-to-back plates together form a second module first fluid conduit for said first fluid; and a second heat exchanger, comprising a plurality of stacked tubular members defining a first set of flow channels and a second set of flow channels, wherein at least one of said same fluids in said first heat exchanger flows through said second heat exchanger.
