Near the end of the 20th century, increasing power levels became the primary challenge in system design, which triggered a complex response from electrical, mechanical and material engineers. The combination of thermal measurements and thermal simulation helped achieve thermally aware system designs. However, no real solution was known for the valid comparison of thermal design … [Read more...]

A previous Electronics Cooling article, which discussed the process for analyzing the thermal performance of cooling fans [1], mentioned the need of accounting for the increasing coolant temperature as air passes through a heat sink. That article used an ‘average’ air temperature, which was defined as the midpoint between the inlet and outlet air temperatures. This article … [Read more...]
