Abstract
Heat exchangers constructed of a plurality of composite ribbed sheets plates disposed and in a substantial parallel plate stacked relationship are disclosed. The sheets or plates can be spaced from each other by composite ribs or bars formed integral with or bonded to and between adjacent plates. The composite plates function as the fins of a conventional plate fin heat exchanger while the ribs form the passageways to separate adjacent fluids. The fins are specially constructed to maximize heat transfer between adjacent passageways formed by the ribs and the fluids flowing in these passageways.
Claims16
A heat exchanger comprising:
- first, second, and third carbon/carbon composite plates comprised of a high strength carbon fiber polymeric resin matrix including thermally conductive fibers oriented for providing anisotropic thermal conductivity in said composite plates, said plates being disposed in substantially parallel spaced relation, first and second plates defining a first fluid flow passageway therebetween and said second and third plates defining a second fluid flow passageway therebetween;
- a first plurality of corrugated carbon/carbon composite fins comprised of a high strength carbon fiber polymeric resin matrix including thermally conductive fibers oriented for providing anisotropic thermal conductivity in said fins, said fins being disposed between and bonded to said first and second plates of the first passageway for supporting said first and second plates in a stacked relation and to conduct heat from said first passageway to said second plate;
- and
- a second plurality of corrugated carbon/carbon composite fins comprised of a high strength carbon fiber polymeric resin matrix including thermally conductive fibers oriented for providing anisotropic thermal conductivity in said fins, said fins being disposed between and bonded to said second and third plates of the second passageway for supporting said second and third plates in a stacked relation and to conduct heat from said second plate to said second passageway.
A heat exchanger comprising:
- an assembly of a plurality of substantially planar anisotropic composite plates each comprised of a high strength carbon fiber polymeric resin matrix including thermally conductive fibers oriented for providing anisotropic thermal conductivity in said composite plates, said plates being having a plurality of unequally spaced ribs applied to at least one surface of each of said plates, said plates being disposed in substantially parallel spaced relation, and first and second ribs on a first plate being spaced from each other to define a first fluid flow passageway therebetween and second and third ribs on a said first plate being separated to define a second fluid flow passageway therebetween wherein said first and second passageways are separated by the second rib and the fluid flows in the first and second passageways are substantially parallel to said first plate.
