A method of assessing the overall cooling performance in the thermal design of electronics is presented. The method is based on the optimization concept proposed by A. Bejan, whose original idea was related to the trade-off between heat transfer enhancement and pressure loss increase based on an assessment of entropy generation rate. The present report summarizes the research conducted to date and presents a study on the optimization of cooling systems.
