Abstract
A composite parallel plate heat exchanger is provided constructed of a plurality of composite plates disposed in a substantial parallel stacked relationship and spaced from each other by composite ribs inserted through and bonded between adjacent plates. The composite plates and ribs are specially constructed to maximize heat transfer between adjacent passageways formed by the plates and the fluids flowing in these passageways.
Claims13
A composite heat exchanger comprising:
- a free-standing structure of first, second, and third high-strength fiber-matrix composite plates disposed in substantially parallel spaced relation, the first and second plates defining a first fluid flow passageway therebetween and the second and third plates defining a second fluid flow passageway therebetween;
- a plurality of high-strength fiber-matrix composite ribs inserted through and bonded to said first, second, and third plates supporting said plates in a stacked relation, and to conduct heat from said first passageway to said second passageway;
- said high strength fiber-matrix composite including thermally conductive fibers oriented so as to impart an anisotropic thermal conductivity to said composite plates and/or ribs;
- and
- a stacked array of alternating first and second passageways to form a durable, integrated heat exchanger.
