Extrusion Process Analysis and Evaluation of Integrity for Condenser Tube by Using CAE

CAE를 이용한 컨덴서 튜브의 직접압출공정 해석 및 튜브 건전성 평가

This paper describes the analysis of extrusion process and integrity for the condenser tube which is component of the heat exchanger in automobile and air conditioning apparatus. As development of the analysis method using computer, recently. It have been applied to the 3-dimensional hot extrusion process with complex section area of the non-steady statement and then results of the analysis have been applied to optimal die design and process design. As the result, this paper confirmed that used extrusion die of the research is satisfactorily designed to dimensional accuracy. And the stress point of view, condenser tube confirmed that it was influenced by the flow pressure of alternative regrigerants.
