Question

Discuss important factors in selecting a heat sink.

Answer 1

Some of the key factors that should be considered in heat sink design include thermal resistance, material, fin configuration, fin size and shape, fin efficiency, heat sink attachment method, and thermal interface material.

Answer 2

Answer

The flow of the coolant medium is greatly impacted by the arrangement of fins on a heat sink. Optimizing the configuration helps to reduce fluid flow resistance thus allowing more air to go through a heat sink. Its performance is also determined by the shape and design of its fins.
