Middle East Technical University Department of Metallurgical & Materials Engineering Heat Sink Design for Thermal Management of Electronics Uğur ALAKOÇ Lead Design Engineer Radar and Electronic Warfare Systems Sector EW Receiver/Transmitter Technologies Department Heat sinks are mechanical structures used to transfer heat efficiently. They are the main heat removal mechanisms for thermal management of electronics. As technology advances heat fluxes in integrated circuits are getting higher and the demand for advanced thermal control techniques are increasing. In order to decrease size, weight and power requirements of military systems and to cope with increasing hot spots, state of the art heat sinks and cooling methods need to be developed. In this presentation, heat sink design process from conceptual design to production will be discussed in detail. First of all, overview of heat sinks and thermal management methods will be presented. Then, design process of heat sinks will be given in preliminary design and detailed design phases. The detailed design phase will be focused on thermo-mechanical design, electronics cooling applications and how to do thermal simulations. Finally, the talk will conclude with a briefing of production and verification methods.
