摘要：

This paper presents a life prediction method based on several accelerated life test data for brazed plate heat exchanger. For this purpose, accelerated life tests were performed with pressure cycle and fluid temperature as accelerating stresses. Statistical analyses of the two test data sets and their combination were conducted. As a result, the shape parameter of Weibull distribution, the accelerating index of pressure cycle, the activation energy, and the life cycles under normal use conditions for the brazed plate heat exchanger were obtained.
