Title: Methods of making plate-fin heat exchangers

Abstract: A method of making a heat exchanger includes assembling one or more heat exchange cells. Each heat exchange cell is assembled by providing a top plate having an inlet aperture at one end thereof, an outlet aperture at the other end thereof, a first surface, a second surface and peripheral edges; and providing a bottom plate having an inlet aperture at one end thereof, an outlet aperture at the other end thereof, a first surface, a second surface and peripheral edges. The second surfaces of the top and bottom plates are juxtaposed with one another so that the inlet and outlet apertures of the plates are in substantial alignment with one another. The peripheral edges of the top and bottom plates are attached to form a high pressure chamber between the second surfaces of the plates. After being assembled, each individual heat exchange cell is tested before being attached to other heat exchange cells. The testing may include pressure testing of the heat exchange cell. The testing of each individual cell improves the quality and reliability of the fully assembled heat exchanger because each level of the heat exchanger has been pre-tested for defects (e.g. leaks) prior to further assembly steps.
