composite heat exchanger with reinforced joints

摘要

A heat exchanger core includes a stack of fins, plates and closure bars. A first plurality of stiff fibers extend into contacting surfaces of the fins and plates, a second plurality of stiff fibers extend into contacting surfaces of the closure bars and plates, and a third plurality of stiff fibers extend into contacting surfaces of the closure bars and manifolds. The stiff fibers can strengthen the heat exchanger assembly and they can also increase thermal conductivity in their direction of orientation.
