ABSTRACT
Research and optimization of cooling of electronic components using heat sinks becomes increasingly important in modern industry. Numerical methods with experimental real world verification are the main tools to evaluate efficiency of heat sinks or heat sink systems. In this research, the physical problems associated with heat removal of electronic systems at different scales were studied. Various electronic cooling system designs and specific cooling techniques to improve performance were discussed. Optimization procedures and suggestion for better design was proposed. Power dissipation performance must be well understood prior to integrating devices on a circuitboard to ensure that any given device is operated within its defined temperature limits. When adevice is running, it consumes electrical energy that is transformed into heat. Most of the heat is typicallygenerated by switching devices like FETs, ICs, etc. The relationship between the reliability and the operating temperature of a typical silicon semiconductor device shows that a reduction in the temperature corresponds to an exponential increase in the reliability and life expectancy of the device. Therefore, long life and reliable performance of a component may be achieved by effectively controlling the device operating temperature within the operating limits. This report discusses the thermal dissipation terminology and how to design a proper heat sink for a given dissipation limit.
