本文主要介绍钎焊板式换热器结构及其真空钎焊工艺参数的选择原则，以及由此得出的真空钎焊工艺参数曲线，并按此曲线进行钎焊工艺评定。通过试验完全满足ＡＳＭＥＢＰＶＣＯＤＥＳＥＣⅨ中有关验收标准。
This article mainly introduces the selection principle of brazing plate heat exchanger structure and vacuum brazing process parameters, and the resulting vacuum brazing process parameter curve, and brazing process evaluation based on this curve. Through the test fully meet the acceptance criteria ASMEBPVCODESECIX.
