摘要/Abstract

摘要： 介绍了板式换热器的工作原理；分析了其主要部件换热板片的微变形能力（该特性容易被忽视），即在换热器某侧的压力变化时，会影响板片形状，造成换热器内部两侧的容积发生变化，从而引起另一侧压力波动；讨论了该特性在实际应用中存在的案例，给出了处理对策。

Abstract: The operating principle of plate exchanger was introduced. The microdistortion characteristic of the heat exchange plate was analyzed which was ignored easily. The microdistortion means that the pressure variation on one side of exchanger will influence the shape of the heat exchange plate, and which causes the volume inside the exchanger between the both side to vary and the pressure on another side of the exchanger to fluctuate. The practical example of microdistortion was discussed, and relevant handling measure was given.

Key words: plate exchanger, heat exchange plate, micro-distortion characteristic, volume change, handling measure
