Thermal Resistance Measurement of Finned Heat Sinks
Modern electrical devices often use high- performance semiconductors whose operation is accompanied by a considerable amount of heat. Cooling of such semiconductors is usually carried out by aluminum heat sinks with or without forced airflow. It is very often necessary to determine the actual performance of the heat sink by measuring. Such cases may occur either when appropriate technical data are not available from the manufacturer, or if operating conditions change that were not foreseen by the manufacturer, or if heat sinks, which are available for use, are reused after recycling electronic products and hence technical data is unknown. In these cases, it is necessary to determine the thermal resistance of the heat sink by measuring. The measurement procedure should be simple, measurement equipment cheap, and the measurement results reliable. One such measurement procedure is shown in the paper. The paper presents a simple and reliable measuring technique for determining the thermal resistance of ribbed heat sinks. The presented measuring technique requires neither expensive equipment nor specific qualifications from the measurer. The theoretical framework and the corresponding mathematical foundations are presented in a simple, obvious and understandable way, and the application is shown on a practical example. The obtained measurement results are analyzed and interpreted.
