Definitions

  • This invention relates to plate-stack heat exchangers and especially to plate-stack heat exchangers with internal manifolding.
  • Finned-plate heat exchangers are mainly of the channel and rib-type construction. Countercurrent flow can be achieved; however, manifolding a plate stack which must separate the fluids at entry and exit becomes extremely complex. Since the manifolding of the crosscurrent heat exchangers is comparatively simple, this heat exchanger system is more widely used although it is less efficient than the countercurrent system and it induces serious thermal and mechanical stresses.
  • Campbell et al U.S. Patent No. 3,305,010.
  • Campbell et al teach a heat exchanger having superposed stacked plate and fin elements and complex manifolding means for introducing fluids of different temperatures into opposite ends of the assembly.
  • Campbell et al do not teach a plate which serves as both the plate and the fin, nor does Campbell et al teach means for internally manifolding the plate within the plate's plane.
  • One of the problems in the stacked plate type of heat exchanger is the blocking of a selected internal port at any stack level to prevent fluid flow from the selected port through the channels on that level and, thus, to force the fluid through the port to the next level where it is permitted to flow through the channels.
  • An object of the present invention is to provide a finned plate for an internally manifolded plate-stack heat exchanger.
  • Another object is to provide a simple means for blocking the flow from a fluid-inlet port at a given plate level in a plate-stack heat exchanger and for passing that fluid through to a fluid-inlet port in the next higher plate.
  • the invention comprises an internally manifolded, countercurrent, finned-plate- stack heat exchanger, each interior plate having manifold areas at opposite ends thereof.
  • Flow, or fluid entry, ports are excised through the plates, at least two at each manifold area.
  • the ports and the fins are formed so that the plates can be rotated 180° without the relative overall appearance being changed, i.e., the ports of the rotated plate will still be in mating position with the ports of an unrotated plate when the two plates are stacked.
  • Bushings of compressible, fluid-impervious material are inserted into two diagonally opposite ports in each plate and a gasket is inserted in a groove in the upper surface of the peripheral wall around the plate so that fluid does not flow between the contacting surfaces of the gasket and bushing with the bottom surface of the plate immediately above.
  • Fig. 1 shows a schematic view of two interior, adjacent, finned-channel plates 10 and 12 for a heat exchanger 50 (Figure 3) in accordance with the present Invention.
  • the lower and upper plates 10 and 12 are preferably rectangular and are formed with parallel, longitudinal, upstanding fins 16 which define longitudinal channels 18 between them.
  • the plates may be formed of metal by an extrusion process and areas 20 and 21 (see Fig. 2) can be formed later where the fins 16 are milled off at each end.
  • a pair of spaced fluid-entry ports 22 and 24 are drilled at one end toward the corners of the plates, and another pair of ports 26 and 28 are drilled similarly at the other end.
  • a frame 30 is placed upon and bonded to the periphery of the upper surface of each finned plate, thus forming a wall 31 around the plate and a well or manifold 32, 33 at each end where the fins 16 were milled off.
  • Two diagonally opposite ports on each plate are fitted with a bushing insert 34 which extends upwards as far as the top of the wall 31 of the frame 30 and the tops of the fins 16, the top surfaces of these members forming a flat plane.
  • the bushings 34 are preferably formed from a compressible material, such as a heat-resistant elastomer, in which case they may extend slightly above the aforementioned flat plane, or may be formed from a metal with a groove in the upper surface in which a circular gasket 36, or 0-ring, can be inserted.
  • the frame 30 is also preferably formed with a groove in its upper surface in which a gasket 38 is inserted.
  • the bottom surface of the interior plates 10 and 12, as well as that of the top plate 14, must be flat surfaces so that they make good contact with the gaskets 38 and 36 on the frames 30 and bushings 34 of the plates underneath the surfaces.
  • the gaskets 36 and 38 prevent the passage of fluids.
  • the bottom plate 10' (see Fig. 3) in the stack of plates is formed somewhat differently from the interior plates 10, 12, etc.
  • the bottom plate 10' is formed with only two ports 24' and 28', each in a different manifold area and each on the same longitudinal side of the plate.
  • One port 24' is the entry port for one fluid (B), e.g., cool air
  • the other port 28' is the entry port for a second fluid (A), e.g., hot oil which is to be cooled.
  • a bushing 34 is inserted through the entry port 24' for the fluid which is not to be circulated through the channels 18 in the bottom plate 10' thereby transforming this port into a non-dispersive port, i.e., a port through which the fluid flows only to the next plate 12 above the bottom plate 10'.
  • pressurized fluid A enters the bottom plate 10' through inlet port 28', fills the manifold 33 and a portion proceeds through the channels 18 between the fins 16 and up through the inlet port 22 in the second plate 12.
  • a second portion proceeds directly through the non-dispersive port 28 in the second plate 12 through the inlet port 28 in the third plate 10 where it provides the source of fluid flow to the left as in the first plate.
  • Pressurized fluid B enters the bottom plate 10' through non-dispersive port 24' and is prevented from flowing in the bottom plate 10' by the bushing 34. Fluid B goes through the inlet port 24 in the second plate 12 and fills the manifold 32 on the left side. A portion of the manifold fluid flows to the right through the channels 18 and then up through non-dispersive port 26 in plate 10 and port 26 in plate 11. It leaves the plate stack through the outlet duct 42 1n the top plate 14 which is formed with two outlet ducts, 42 for fluid B and 40 for fluid A. Fluid B always flows to the right in alternate plates, e.g., plates 12 and 11. For fluid B, the ports 24' and 24 1n each plate are inlet ports and the ports 26 diagonally opposite are outlet ports. For fluid A, the ports 28' and 28 are inlet ports and the ports 22 are outlet ports. The flows in the channels 18 for fluid A and B are counterflows.
  • Fig. 4 there is shown a unitary form of construction for a gasket 62 which may be inserted in a groove along the top of the peripheral wall and the circular gaskets 60 which may be put on the top of the bushings 34.
