<p>A heat exchanger plate block (10) is comprised of a stack of consecutive, spaced, parallel rectangular plates (11) mounted within an enclosing frame. The frame has end walls (12) parallel to the plates and corner posts (14) extending between and joining corners of the end walls. Resilient spacers (26) are included between the plates to render the stack of plates elastically compressible as a unit in a direction normal to the planes of the plates. Resilient corner spacers (23) are provided to space corners (34) of the plates from adjacent corner posts to accommodate growth of the plates due to thermal expansion in their planes. The plates of the plate stack hence float within resilient fixtures which accommodate thermal expansion parallel to and normal to the planes of the plates.</p> |
