냉장고 캐비닛의 냉기유로 주변의 환경에 관한 연구

A cabinet of refrigerator is mainly composed of ASS copolymer, polyurethane(PU) foam and steel plate for insulation and support of structure. Outer plate is deformed in the circumference of duct which is interchanged between refrigerating room and freezing room as cold air stream and it is very difficult to prevent deformation because the reasons of deformation are not defined clearly. On this study finite element analysis of theoretical numerical analysis was applied to estimate deformation of cabinet and outer plate of duct region as constructing a finite element model and phenomenal analysis. The factors which affect deformation on outer plate of duct region were evaluated and the new design is also suggested to minimize deformation. It was suggested that the shape of flat duct which has rib at the end part of it can fill the empty space with PU-foam makes a smooth curved surface.
