Natural air-cooling needs neither a fan nor a blower. However, cooling capability of natural air-cooling is low, so the improvement of its capability is indispensable. In this study, the system box is inclined for the purpose to raise the capability of natural air-cooling, and the increase in natural circulation flux in the box is quantitatively proven by(More)
Nowadays, precise prediction of heat generation in semiconductor devices is important. An electro-thermal analysis is an attractive method to predict heat generation in devices. In this analysis, momentum and energy relaxation times are taken as the important parameters. Calculated heat generation density is dependent on the energy relaxation time.(More)
