ABSTRACT:
The invention contemplates an improved sandwich-type core construction for a heat exchanger, featuring light weight without sacrifice of the strength needed for handling elevated pressures. Passages of one set are interleaved with those of another set, using spaced parallel heat-transfer plates. Elongate parallel spacers extending in one direction establish, with their adjacent plates, flow passages of one system, while elongate parallel spacers extending in a different direction establish flow passage of a second system, between paired plates of the first system. The perimeter of the core at ends of at least one of the system passages establishes solid continuous seating for such system headers. Substantial weight saving, without sacrifice of strength, is achieved by depressed excavation of spacer material in regions thereof not involved in header-seating accommodation.
