ABSTRACT:
The invention provides a protective casing for a cube-shaped modular ceramic heat exchanger core, in which the core can easily be installed without danger of leakage between the fluid paths of the core. To this end the core rests in the casing with the edges of one face engaged with a suitable ceramic fibre composition gasket; the opposite face of the same flow path is engaged by another such gasket and the gasket is in turn engaged by a gasket compression member. The compression member is urged into this engagement by strong springs which thereby hold the gaskets in the necessary sealing engagement. In one aspect of the invention the casing is readily changed to provide single or multi-pass of one of the flow paths through the core; such a casing consists of a central portion of the thickness dimension of the core and replaceable end portions which provide the inlet, outlet and respective plenums. In another aspect of the invention the casing provides a central trunk with which a plurality of cores can be used selectively to provide increased heat exchange capacity without substantial increase in pressure drop.
