Abstract

A combined-natural-and-forced-convection heat sink system including a plurality of fins protruding from a first surface of a conductive material, a plurality of air channels formed between the first surface and an opposing second surface of the conductive material and at least one fan. The plurality of fins forms a natural-convection heat sink. The plurality of air channels forms a forced-convection heat sink. The natural-convection heat sink and the forced-convection heat sink form a combined-natural-and-forced-convection heat sink. Each air channel has an input end opening on an input surface of the conductive material and each air channel has an output end opening on an output surface of the conductive material. The at least one fan is configured to generate an air flow through the air channels when at least one of the fans is operating.
