5.2 Thermal circuit modeling

Previous Next

Description

March 26, 2021

In this lecture, we will learn:

Heat flow problems usually look just like resistor-capacitor circuits.
Thermal circuits are an intuitive way to understand heat flow.
Minimizing thermal resistance to a thermal sink keeps power-dissipating devices cool.
