Heat Pipes and Heat Exchangers What is a heat pipe? A heat pipe is a heat transfer device with an extremely high effective thermal conductivity. Heat pipes are evacuated vessels, typically circular in cross section, which are back-filled with a small quantity of...
The Benefits of Components & Systems Designers sometimes oversize components in order to build in a margin of safety. However, this safety factor can add quite a bit to the cost of operating your system. What may be less obvious, perhaps, is how this safety factor...
Gathering Critical Device Data Finding how much heat your electronic device dissipates and how to calculate maximum case temperature can be difficult if you’re not sure what you’re looking for. But determining the amount of heat a device dissipates is one...
Heat Spreading Heat spreaders offer cost-effective, reliable high thermal conductivity and efficacy with almost no moving parts. A heat spreader is an effective solution for dealing with heat sources that have a high heat-flux density (high heat flow per unit area)...
The following is a brief overview of some fundamental heat transfer concepts. To learn more, the reader is encouraged to review the source publications and cited websites Introduction to Thermodynamics 1st and 2nd Laws of Thermodynamics The 1st Law of Thermodynamics...
Input Power versus Dissipated Power For those new to thermal management, most devices have two associated power values: input power and dissipated power. Input power is the product of electrical input current and voltage to the device. This is what electrical...
