An annular heat exchanger assembly includes a plurality of low thermal growth ceramic heat exchange members with inlet and exit flow ports on distinct faces. A mounting member locates each ceramic member in a near-annular array and seals the flow ports on the distinct faces into the separate flow paths of the heat exchanger. The mounting member adjusts for the temperature gradient in the assembly and the different coefficients of thermal expansion of the members of the assembly during all operating temperatures.

A heat exchanger assembly for exchanging heat between different temperature fluids in first and second flow paths comprising: (a) at least one ceramic member having first fluid passages defining a heat exchange portion of said first flow path and second fluid passages defining a heat exchange portion of said second flow path, said ceramic member having a hexagonal cross-section such that the top and bottom of the ceramic member each have a pair of adjoining oblique faces which terminate in a squared-off portion forming a ridge therebetween, and each of said first and second fluid passages including inlet and exit flow ports disposed on said oblique faces; (b) sealing material surrounding each inlet and exit port, and (c) mounting and sealing means for mounting said ceramic member in said first and second flow paths and sealing said first and second fluid passages in said first and second flow paths respectively whereby said mounting and sealing means is operative to adjust for different coefficients of thermal expansion between said ceramic member and said mounting means, said mounting and sealing means including: (i) top and bottom compression members each having a portion adapted to define a channel of cross-section substantially the same as the pair of oblique faces of said ceramic member, said channel having a plurality of apertures therein ech disposed adjacent one of the inlet and exit flow ports with the sealing material therebetween whereby each flow port is sealed in flow communication with one of the apertures; and (ii) means for resiliently holding the channel portion of said compression member in compression against said pair of adjoining oblique faces of said ceramic member and the sealing material of each inlet and exit port thereof wherein said squared-off portion forming a ridge provides a clearance space between said ceramic member and said channel portion of said compression member during thermal expansion.
