Abstract
A method for making a heat exchanger includes machining a plate of material having a starting thickness and at least one alignment feature. The machining includes machining down the starting thickness to produce a heat exchanger plate having at least one flow passage segment and at least two ribs arranged extending along each side of the at least one flow segment. The at least one alignment feature is removed to provide a trimmed heat exchanger plate and to stack the trimmed heat exchanger plate with a further heat exchanger plate. The at least two ribs are interlocked with ribs of the further heat exchanger plate and the at least one flow segment is aligned with a flow segment of the further heat exchanger plate. The at least two ribs of the trimmed heat exchanger plate and the ribs of the further heat exchanger plate are joined together.
