Detachable clamp for fixturing heat exchanger core assemblies for brazing in combination with the heat exchanger core
In combination, a heat exchanger core is described having reinforcements extending along opposite sides and headers at opposite ends, a detachable clip for separately fixturing each of the reinforcements to one of the headers during brazing of the core and the reinforcements to the headers at junctures. The reinforcements may be assembled prior to brazing with substantial air space at their junctures with the headers but not exceeding a prescribed limit, characterized by the clip being made of a material having a coefficient of thermal expansion substantially less than the reinforcements so as to draw the reinforcements and headers together during brazing through a distance at least equal to the prescribed air space limit to thereby assure contact at all the junctures between the reinforcements and headers during the brazing thereof.
