Abstract
Abstract A stacked plate heat exchanger 10 which employs two types of finned plates for providing cross-flow of fluids, especially for cooling a hot liquid flow by a gas flow. The first plate 12 has a flat bottom 16 and a peripheral wall 26 on the top side. The central region of the plate 12 supports upstanding spaced fins 20 forming channels 22 the ends of which are contiguous with internal manifolds 24 at the end regions of the plate 12. A manifold port 28 is formed through the plate 12 in each end region. The second plate 14 has a flat bottom 34 and spaced fins 20' forming channels 22' in the central region extending downwardly from the top surface 36 of the plate 14. The end regions each have a manifold port 28' extending therethrough in the same locations as the manifold ports 28 of the first plate 12 so that interior manifolds are formed thereby when the plates are stacked. The top surfaces of the fins 20 and peripheral wall 26 of the first plate 12, and of the fins 20' and the end regions of the second plate 14, form flat planes.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
273 words
A plate stack assembly for a heat exchanger comprising: at least one first plate having a flat bottom and an upstanding peripheral wall on the top side thereof and upstanding spaced fins In the central region of said top side forming channels therebetween, the heights of the peripheral wall and fins being identical, the plate having opposed internal manifold regions between said fins and the peripheral wall at each end, each manifold region being formed with a manifold port therethrough from top to bottom of said plate, the axes of the fins being substantially in the same direction as a line connecting the manifold ports; and at least one second plate of the same shape and dimensions as the first plate except In the direction transverse to the plane of the plates, said second plate having a flat bottom and upstanding spaced fins In the central region of the top side thereof forming channels therebetween and having opposed end regions the heights of which are identical with the heights of said fins, each said end region being formed with a manifold port therethrough at the same location as the first-plate manifold port at the same end, the axes of the fins being substantially crosswise to a line connecting the manifold ports, so that when said first and second plates are stacked, said manifold ports coincide to form a different transverse manifold at each end and the bottom of one plate is in contact with the upper edge of the fins on the other plate below to form covered channels in said other plate, the flows of fluids through said plates being cross flows.
Claim 2
Dependent Claim
273 words
A plate stack assembly for a heat exchanger comprising: at least one first plate having a flat bottom and an upstanding peripheral wall on the top side thereof and upstanding spaced fins In the central region of said top side forming channels therebetween, the heights of the peripheral wall and fins being identical, the plate having opposed internal manifold regions between said fins and the peripheral wall at each end, each manifold region being formed with a manifold port therethrough from top to bottom of said plate, the axes of the fins being substantially in the same direction as a line connecting the manifold ports; and at least one second plate of the same shape and dimensions as the first plate except In the direction transverse to the plane of the plates, said second plate having a flat bottom and upstanding spaced fins In the central region of the top side thereof forming channels therebetween and having opposed end regions the heights of which are identical with the heights of said fins, each said end region being formed with a manifold port therethrough at the same location as the first-plate manifold port at the same end, the axes of the fins being substantially crosswise to a line connecting the manifold ports, so that when said first and second plates are stacked, said manifold ports coincide to form a different transverse manifold at each end and the bottom of one plate is in contact with the upper edge of the fins on the other plate below to form covered channels in said other plate, the flows of fluids through said plates being cross flows.
