波纹管是高效换热器,特别是余热回收和地温差换热器中广泛使用的核心换热元件,其刚度特性对换热设备的寿命影响巨大。本文以波纹管的实际约束和受力状况为基础,采用限单元法分析其刚度情况,得到了波纹管的刚度分布规律,为工业应用提供了可靠的设计依据。
Bellows is a highly efficient heat exchanger, especially heat recovery and geothermal heat exchangers are widely used in the core of the heat exchange element, the stiffness characteristics of the life of heat exchange equipment has a huge impact. Based on the actual restraint and stress of the corrugated pipe, the finite element method is used to analyze the stiffness of the corrugated pipe. The stiffness distribution of the corrugated pipe is obtained, which provides a reliable design basis for industrial application.
