This slide presents the typical steps to select a heat sink. The first step is to identify the device to be cooled, followed by calculating the thermal resistance required based on the specifics of application. Proceed to www.aavidthermalloy.com and search for the section dedicated to this type of device. Review the results and compare the size, mounting direction, performance and options offered to what the calculated needs and parameters are. Once a heat sink is found which will meet the requirements, the part-specific page will show a representative photo, part description info, mechanical drawing, and the thermal curves for natural and forced convection.
