Method of forming reinforced plate-type heat exchanger

摘要

In brazed aluminum heat exchangers of plate type composed of piled heat exchanger units each comprising corrugated fin within the space defined by two sheets and side bars arranged at both ends of the plates, an improved heat exchanger comprising placing a thick bare member on the brazing sheet of the outer plate materials of the outermost units as a reinforcing member and brazing integrally by fluxless brazing procedure, thereby eliminating any special member.
