MCM marked the emergence of electronic assembly technology in high density, high speed, high performance into a higher level in the direction. However, with the improvement of MCM integrated and volume reduction, increasing power consumption in its unit volume, resulting in increased heat and temperature rising sharply, thus strengthening the formation of a component driven by internal heat mechanical, chemical and electrical, and other aspects of interaction. If the structure or design materials selection is unreasonable, MCM heat cannot be disseminated quickly while you work out, can lead to excessive temperature gradient inside and outside the MCM, in the formation of MCM internal overheating or hot spots makes components performance worse. Therefore, the MCMs thermal design and research on heat dissipation technology has a very important role. Currently, the MCM method of heat sink variety of cooling is more general, because cheap air cooling cost easy to use. This selection of air cooling radiator model, application of ANSYS software to the MCM thermal analysis you select. Choose a different material analysis and comparison of different models of heat sink thermal. Integrated fan motor, selecting optim
