Concept of modularity is useful to development of the product design for variety. Therefore, shortening the thermal design cost, we developed and applied an approach of modeling for reuse of design knowledge for switchgear based on modularity. First approach is Global-Local (Zooming) modeling approach. It is the approach that inner temperatures and air flows of switchgear are estimated approximately by Global model, details of them are obtained from Local models. Global and Local models are linked by the thermal interfaces for boundary condition used the thermal analysis results of Global model. Using this modeling approach, it is possible to study design parameters on module-based. Second approach is to establish the thermal design system by using design knowledge to reduce the cost of thermal design. And we verified that the thermal system using this approaches is available, thermal design cost is reduced by 80% at the case of 3module parameters.
