Design Optimization of Evaporator Clip by FEA (ANSYS)

Structural rigidity of refrigerator components is one of the important aspects of refrigerator’s structural design for its safe and efficient operation. Generally, the loading conditions are severe during the transportation of the product. To ensure safe transportation, design has to withstand transportation test. We were referred to a component, evaporator clip, which failed during a standard transportation test. Evaporator clip is an aluminum alloy component which holds the evaporator tube assembly in place. The two evaporator clips, shaped like “J” hooks, were getting straightened during the transportation test. A dimple in the hook was indenting the very tube where it was supported.
