Electronics Enclosures Thermal Issues

Electronics Enclosures Thermal Issues. Instructor: Prof. N. V. Chalapathi Rao, Department of Engineering Design, IISc Bangalore. Electronics Design is understood as analysis and implementation at various levels from large systems installation to chip design. One of the aspects is failure due to temperature effects is constantly under study. Theory of Heat transfer has been understood and explained way back in 1700. Rigor and precision has resulted in seemingly complicated equations. In the design of enclosures, managing heat is (relatively) well understood. Empirical results can be used to optimise the layout and reduce failure. Practices in use of heat management hardware are available from specialist manufacturers and can be used. This course is an attempt to familiarise the participating registrants with heat related issues in Design of Electronic Product enclosures. (from nptel.ac.in)
