PROCESS FOR COPARALLEL JOINING OF PLATE METAL BY BRAZING, IN PARTICULAR FOR PREPARING A PLATE-SHAPED HEAT EXCHANGER, AND HOLDING MEANS THEREFOR

摘要

A method of assembling in parallel by brazing together two metal plates at least each pierced with at least one hole, in particular for producing a plate heat exchanger which comprises brazing the plates in question in the now parallel to the other, the holes are held one facing the other by means of a fixing part bent at the edges of said holes. During brazing, the fastener secures the metal plates so as to provide very small interstices between the sides of the fastening part and the plates and between two consecutive plates. In addition, the fastener can be used to deposit the solder in the solder joint area.
