具有中央加强循环管的换热器强度分析

Strength Analysis of Heat Exchanger with Consolidation and Circulation Central Tube

具有中央加强循环管的换热器，因其结构的复杂性，不易进行精确分析。本文对此进行了系统地分析，将中央加强循环管化为管板的弹性支座，而将其余的循环管化为管板的弹性基础。这样本文提出了一套弹性支座支承的弹性基础板的解法，使这一复杂结构的精确分析成为可能。

This paper analyses systematically the strength problem of heat exchanger with a consolidation and circulation central tube, which is considered as an elastic support of the tube plate, the others of the exchange as an elastic foundation of the tube plate. A kind of solution to elastic foundation plate supported by elastic support is discussed in detail.
