The present invention relates to a heat exchanger panel which has broad utility
in high temperature environments. The heat exchanger panel has a first panel, a
second panel, and at least one fluid containment device positioned intermediate
the first and second panels. At least one of the first panel and the second panel
have at least one feature on an interior surface to accommodate the at least one
fluid containment device. In a preferred embodiment, each of the first and second
panels is formed from a high conductivity, high temperature composite material.
Also, in a preferred embodiment, the first and second panels are joined together
by one or more composite fasteners.
