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.
