Heat exchangers are important components in many industries, including power generation, petrochemical, and pulp and paper. These devices contain large numbers of tubes arranged in arrays. The purpose of these devices is to exchange heat between internal and external cooling and heating fluids. A great deal of energy is transported in the form of high pressure and heat. If a fraction of this energy is transformed into vibrations, a form of mechanical energy, the tube integrity will be compromised.

热交换器是许多行业的重要组成部分，包括发电，石化以及纸浆和纸张。这些设备包含在阵列中排列的大量试管。这些设备的目的是在内部和外部冷却和加热流体之间交换热量。以高压和热量的形式运输了大量能量。如果将此能量的一部分转化为振动，则一种机械能的形式，则管道完整性将受到损害。
