Heat Sinking to Improve Power Density (.PDF Download)

Read this article online.

Today’s electronic power architectures demand high power density even in the presence of increased heat generated by various devices in these designs. The challenge is to cool those devices with a cost-efficient component known as the heat sink. Creating an optimally designed heat sink will improve a power supply’s power density, device reliability, performance, and service life.

Power density is defined as the ratio of power-converter output power to converter volume. This is an important parameter characterizing the compactness of power electronic systems.
