空调系统零部件可靠性试验设计

摘要

空调系统中电子元器件的可靠性试验包括冷热冲击试验和加速寿命试验,本文以温度传感器和风机驱动电路板为例,介绍如何根据零部件的具体使用情况,设计其可靠性试验,进而对其失效形式及实际使用寿命进行有效评估.%The reliability tests on the electronic components in the air-conditioning sys-tem include the thermal shock test and accelerated life test.Taking the temperature sensor and fan drive board as the example,the reliability test design on the components based on their application environment is introduced,and the effective assessment on the failure mode and the actual life time is conducted.
