Abstract: A plate type heat exchanger having a plurality of stacked plate pairs made up of first and second plates. Each plate pair has opposed manifold members that form respective inlet and outlet manifolds for the flow of a first fluid through a first set of fluid channels formed by the plate pairs. The manifold members space the plate pairs apart to form a second set of transverse flow channels for the flow of a second fluid. A protrusion member is formed at an end portion of the plates and proximal to each of the manifold members and has a mating surface, such that the protrusion members on the second plate of one plate pair align and abut with the protrusion members on the first plate of an adjacent plate pair thereby reinforcing and strengthening the manifold region of the heat exchanger to prevent deformation of the manifold under pressure.

Abstract: A plate type heat exchanger is disclosed having a plurality of stacked plate pairs made up of first and second plates. Each plate pair has opposed manifold members with respective inlet and outlet openings that are in registration to form respective inlet and outlet manifolds for the flow of a first fluid through a first set of fluid channels formed by the plate pairs, the manifold members spacing the plate pairs apart to form a second set of transverse flow channels for the flow of a second fluid. Each plate has a peripheral edge portion which seals the plates together to form the first set of fluid channels therebetween.

Abstract: A heat exchanger in which a heat exchanger core is disposed within a casing which includes a side wall formed by bending a plate into the form of a sleeve in which edges of the plate are in adjacent, confronting relationship with an inwardly projecting, transversely extending deformation, the deformation being disposed between a pair of press members with one of the press members being transversely inserted within the sleeve. The press members are moved together to remove the deformation with resultant pivoting of the edges into abutting contact or overlapping relationship. The heat exchanger core is formed of a plurality of stacked plate pairs each having a plate in inverted orientation. Outwardly projecting ribs of anticlastic form are so formed in each plate that the ribs on each plate of each plate pair are interengagingly intersect with the ribs on the adjacent plate of the adjacent plate pair accurately to align the plate pairs in the heat exchanger core.
