Claims
- 1. A fin plate for a plate/fin-type heat exchanger, which consists essentially of:
- an open-faced unibody plate, for channeling a fluid;
- one interior corner inlet oriented perpendicularly through the plane of said open-faced plate;
- one interior corner outlet oriented perpendicularly through the plane of said open faced plate and located at the opposite end from and on the same side as said interior corner inlet;
- one pair of interior corner manifolds comprising an interior corner inlet manifold contiguous with said interior corner inlet and an interior corner outlet manifold contiguous with said interior corner outlet;
- a plurality of contact fins and channels within the plane of said open-faced plate and interposed said pair of interior corner manifolds;
- a pair of transfer ports each perpendicularly oriented through the plane of said open-faced plate and positioned one each in the remaining two corners of said fin plate, closed to fluid flowing along said fin plate, for providing continuous flow passages through said open-faced plate; and
- a flat bottom for mating with said contact fins and said open face of an adjacent plate.
- 2. The plate of claim 1 wherein said means for internally manifolding comprises a tapered slot.
- 3. The plate of claim 1 wherein said means for internally manifolding further comprises at least one manifold fin.
- 4. The plate of claim 1 wherein said fins ae in line.
- 5. The plate of claim 1 wherein said fins are intermittent.
- 6. A heat exchanger, consisting essentially of:
- an internally manifolded plate stack, wherein said plate stack consists essentially of a cover plate, and a plurality of internally manifolded plates stacked in an opposed manner in alternating sequence and wherein each plate consists essentially of:
- an open-faced unibody plate, for channeling a fluid; one interior corner inlet oriented perpendicularly through the plane of said open-faced plate;
- one interior corner outlet oriented perpendicularly through the plane of said open faced plate and located at the opposite end from and on the same side as said interior corner inlet;
- one pair of interior corner manifolds comprising an interior corner inlet manifold contiguous with said interior corner inlet and an interior corner outlet manifold contiguous with said interior corner outlet;
- a plurality of contact fins and channels within the plane of said open-faced plate and interposed said pair of interior corner manifolds;
- a pair of transfer ports each perpendicularly oriented through the plane of said open-faced plate and positioned one each in the remaining two corners of said fin plate, closed to fluid flowing along said fin plate, for providing continuous flow passages through said open-faced plate; and
- a flat bottom for mating with said contact fins and said open face of an adjacent plate; and means for externally manifolding said corner inlets and outlets.
- 7. The heat exchanger of claim 6 wherein said means for internally manifolding comprises a tapered slot.
- 8. The heat exchanger of claim 6 wherein said means for internally manifolding further comprises at least one manifold fin.
- 9. The heat exchanger of claim 6 wherein said fins are in line.
- 10. The heat exchanger of claim 6 wherein said fins are intermittent.
