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.
Claims10
A method of fabricating a composite heat exchanger comprising the steps of:
- providing a plurality of substantially planar high-strength fiber-matrix composite plates;
- providing a plurality of high-strength fiber-matrix composite ribs;
- inserting the ribs in a transverse direction through the composite plates;
- wherein the composite ribs and/or the composite plates comprise thermally conductive fibers oriented so as to impart an anisotropic thermal conductivity to the composite ribs and/or the composite plates;
- separating the plates along the ribs to position the plates in spaced relation and thereby define first and second flow passageways therebetween;
- and
- bonding the plates and ribs to fixedly position the ribs relative to the plates whereby a free-standing composite heat exchanger structure is achieved.
