Definitions

  • This invention relates to plate/fin-type heat exchangers, and more specifically, to a unibody open-faced plate for plate/fin-type heat exchangers using countercurrent or parallel flow.
  • the plate/fin-type 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. In that 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.
  • the gaskets in the Alfa-Laval system are cemented to the plates-in pressed tracks, and are generally made of elastomers like natural rubber, nitrile, butyl, neoprene,viton, etc.
  • the material selection depends upon the working conditions; however, the upper limits are about 360 PSI and about 400°F.
  • the present invention can be distinguished from that of Alfa-Laval in many ways, some of which include: (1) that the Alfa-Laval system requires gaskets which limit operating pressure and temperature; (2) that the Alfa-Laval system has no contact fins or essential flat plate bottoms for providing the plate-to-plate contact necessary to obtain the optimum heat transfer coefficient; (3) the fact that the inlets and outlets of the Alfa-Lavel system are positioned on opposite ends but on the same side of the plate results in a mal- distribution of flow across the plate and inefficient heat transfer; and (4) that Alfa-Laval provides no means for driving the incoming fluid across the face of the plate, thereby correcting for their inherent inefficiencies.
  • an open-faced internally manifolded unibody fin plate for use in a plate/fin-type heat exchanger.
  • Each open-faced internally manifolded unibody fin plate comprises a side port contiguous with an internal manifolding means and wherein the manifolding means is transverse to a plurality of channels, and wherein each channel is contiguous with an end port.
  • a plurality of the open-faced internally manifolded unibody fin plates can be stacked in an opposed manner in an alternating sequence. This internally manifolded plate stack can then be combined with external manifolds to yield an efficient low-cost countercurrent heat exchanger.
  • Another variation of the open-faced unibody internally manifolded plate would include integral auxiliary inlet and outlet manifolds, thereby eliminating the need for separate external manifolding.
  • Another object of the present invention is to provide a one-piece internall) manifolded fin plate for a plate/fin-type heat exchanger.
  • a second fluid of either higher or lower temperature is similarly introduced through the side ports 14 of the next alternating fin plate resulting in countercurrent flow.
  • this is the preferred direction of flow, it is within the scope of this invention to have flow in a reverse manner where in the fluid enters through end ports 24, flows down the channels 20 into'the internal manifold 16, and exits through side port 14.
  • the flow could also be parallel by introducing one fluid through the side port 14 and the other fluid through the end port 24 of the adjacent fin plate.
  • the first and second fluids may be the same or different and that depending upon thermodynamic requirements, more than two fluids may be used.
  • the internal manifolding feature allows for both a minimum flow entrance loss and the internal manifold design provides for heat exchange within the manifold section; thus providing for the highest efficiency in a given length design.
  • the proposed plate stack design, Fig. 12c, heat exchanger provides for the optimum counterflow design together with extended surface finned construction and no corrugations (if minimum pressure loss is desired).
  • a principal advantage is the intimate thermal joint provided by the plate stack which provides for thermal improvements for (almost) all circumstances.
  • the plate-to-plate contact will mean the benefit of the superior thermal conduction of the metal not only between two adjacent plates but from other plates far removed from the immediate thermal joint.
  • the added ability of the design to improve heat conduction results from the three-. dimensional thermal conduction within the plate stack.
  • the better 3-D thermal conduction in the design also reduces the peak thermal stresses by the proportionate reduction in peak surface temperatures within the exchanger.
  • Fig. 13 illustrates for the designs, the requirements of S' vs heat transfer coefficient. For all but the highest heat transfer rate conditions, a practical thickness can be found to use the IMPS plate stack approach.
  • the overall heat transfer rate q/A for the plate stack heat exchanger on a unit surface area basis between plates may be expressed as (approximately): with more detailed analyses performed by computer solution.
  • the cold side and hot side heat transfer coefficients (H h and H c ) become specified, and the wall heat flux can be optimized by the geometry and material selection.
