Abstract
A new user-friendliness multimedia thermal CAD system for thermal design of electronics multilayer structures integrated with a compact cold plate has been successfully developed on Microsoft Windows 98 system. New multimedia technologies, such as voice helper, graphical illustrations, and animated Graphics Interchange Format, employed in the present developed CAD system provide a very friendly and interactive interface for users. The fundamental design concepts for the developed pre-processor, thermal analyzer, and post-processor on Microsoft Windows 98 system are introduced. The developed pre-processor includes six options such as the selections of heat sources, multilayer structure, cold-plate core, working fluid, ambient conditions, and current data. In addition, an improved thermal analyzer has been successfully developed. It can deal with the thermal design problem for compact cold plates coupled with an N-layer structure (N > 4), which has arbitrary asymmetric heating loads. Based on an improved algorithm for drawing isotherms, an interactive post-processor has also been successfully developed on Microsoft Windows 98 system. Finally, the integration of multimedia thermal CAD system for multilayer structures with compact cold plates has been achieved. With the developed thermal CAD system, practical thermal design cases for multilayer structures integrated with compact cold plates have been performed. The superiority of the present developed CAD system has been demonstrated in the present study.
