Abstract
The purpose of this study is to evaluate a structural integrity of plate type heat exchanger considering the behavior of the global structure and is to perform finite element analysis and code calculation as the way to verify the structural integrity.

Recently, the research on plate type heat exchanger has been focused on performance improvement considering the shape and size, however, this study is going to establish the criteria for the supporting structure of the plate type heat exchanger integrity.

Structures under internal pressure flat plate, fixed frame and maximum bolt load were evaluated a structural integrity by performing code calculation The advantages of the plate type heat exchanger is that it is easy to assemble and disassemble, which is up to 1.5 times the actual weight of the evaluation of the structural integrity in carrying bar of body part. The allowable bending stress of the beam type structures which carrying bar and support column is applied to 0.66Sy and flat type like a base plate is applied to 0.6Sy. In addition, the maximum deformation allows 6 inch per 100ft.

In this study, the pre-processing module using Visual Basic and ANSYS APDL has been proposed to save time in FE modeling and analysis to improve an accuracy.
