Abstract: Arrangements for supporting a heat exchanger core within a steel frame structure by a hanger system utilizing flexible members pivotably coupled to overhead support beams. Balancing beams are employed to equalize the load transmitted through the system to the support beams. These support systems permit the heat exchanger core to expand in all directions from thermal growth without restraint relative to the frame structure, thereby minimizing thermal fatigue.

Abstract: A heat exchanger plate of single unitary structure and relatively thin material has a deep draw formed through one surface adjacent to each of the opposite ends to provide fluid openings and a lesser depth inner draw formed in the other surface to provide a fluid passage communicating with the fluid openings. The plate is adapted to oppose adjacent plates in a stacked configuration to provide heat transfer between separate fluids flowing through counterflow passages on opposite sides of the plate. The recessed area on one surface of the plate forms a fluid passage with its adjacent plate in the stacked array for flow of a first fluid through the stack from side to side of an enclosing housing. A collar formed around each plate opening by the deep draw is adapted to nest with a corresponding collar of an adjacent plate to provide manifold sections communicating with a second fluid passage.
